With regard to the development of Sanitary Ware market and the continuous development of sanitary ware, in recent years, with the rise of the richest groups in the country, especially the elites of the society, it has taken the lead in realizing the taste of life, and the sanitary ware industry has caused some middle and high-end consumers in large and medium cities in China. The concern is that sanitary products represented by steam rooms, massage bathtubs, shower rooms (screens), ceramic toilets, washbasins, and bathroom cabinets are driven by high-end consumers and have infiltrated from the rich class to civil servants, teachers and white-collar workers in varying degrees. Such consumer groups, that is to say, advocating a "poetic dwelling" lifestyle has become a fashion demand for home culture. Undoubtedly, this industry is in a regional market where domestic economic development is unbalanced, and it is in the market leading or growing stage. Consumers need a longer period of cultivation and awareness of product design aesthetic style, water culture, and bathing culture. As people have already abandoned the idea that the original bathroom only meets a single function, the bathroom has become a place where people enjoy relaxation, warmth and romance. French famous industrial design master. Piano made an alliance with domestic Herbalife Electric to promote the “Kitchen**†with a French style. Its brand core information is “French art lifeâ€. This includes both the clear differences in the brand and the clear delivery of the brand's core values ​​to target consumers. After all, brands are actually humanized products. After clarifying what kind of person the brand is, then as a basic composition (idea), line (behavior), and appearance (vision) of the person will be clear and consistent, and the brand image will be three-dimensional. And how to sell the core value of the bathroom brand, online marketing is a good way. As more and more people begin to use the Internet to understand related product knowledge, more and more sanitary companies pay more attention to network promotion. How to display their own product information to the target consumer's eyes through the online channels has become a topic of concern for many companies. It is dangerous to begin blindly promoting without the analysis of the user population of the product. This will not only take a lot of time and effort, but will not achieve the desired results. To carry out network promotion, first of all, it is necessary to analyze the product-specific user population, to understand well where the user population is concentrated, and to find the right place. The promotion effect achieved is naturally good. After clarifying where the user population and user population often gather, the next step is to develop a targeted network promotion program. When formulating a plan, it is necessary to integrate some promotion methods that are conducive to obtaining the best results. For example, as a sanitary ware manufacturer, you want to use the Internet to promote yourself, so as to achieve the purpose of investment promotion, promotion, etc. The most effective method is of course to choose the largest and most professional e-commerce website in the sanitary ware industry for promotion. Finally, execution capability is also the key to becoming a good promotion. Execution ability, that is, doing things seriously or not, the size of the ability to do things. Doing things is not only serious, but also learn to sum up experience in practical work. This will help to achieve better results in future promotion. Sanitary companies must pay attention to using the most direct and effective methods to promote sanitary ware brands, and they have a distinct development effect and a sense of improvement. A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a spherical ball. In some ball check Valves, the ball is spring-loaded to help keep it shut. For those designs without a spring, reverse flow is required to move the ball toward the seat and create a seal. The interior surface of the main seats of ball check valves are more or less conically-tapered to guide the ball into the seat and form a positive seal when stopping reverse flow.

Ball check valves are often very small, simple, and cheap. They are commonly used in liquid or gel minipump dispenser spigots, spray devices, some rubber bulbs for pumping air, etc., manual air pumps and some other pumps, and refillable dispensing syringes. Although the balls are most often made of metal, they can be made of other materials, or in some specialized cases out of artificial ruby. High pressure HPLC pumps and similar applications commonly use small inlet and outlet ball check valves with both balls and seats made of artificial ruby, for both hardness and chemical resistance. After prolonged use, such check valves can eventually wear out or the seat can develop a crack, requiring replacement. Therefore, such valves are made to be replaceable, sometimes placed in a small plastic body tightly-fitted inside a metal fitting which can withstand high pressure and which is screwed into the pump head.
There are similar check valves where the disc is not a ball, but some other shape, such as a poppet energized by a spring. Ball check valves should not be confused with Ball Valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow.
A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve. Pressure on the upstream side must be greater than the pressure on the downstream side by a certain amount, known as the pressure differential, for the check valve to open allowing flow. Once positive pressure stops, the diaphragm automatically flexes back to its original closed position.
A swing check valve or tilting disc check valve is check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle. Although swing check valves can come in various sizes, large check valves are often swing check valves. The flapper valve in a flush-toilet mechanism is an example of this type of valve. Tank pressure holding it closed is overcome by manual lift of the flapper. It then remains open until the tank Drains and the flapper falls due to gravity. Another variation of this mechanism is the clapper valve, used in applications such firefighting and fire life safety systems. A hinged gate only remains open in the inflowing direction. The clapper valve often also has a spring that keeps the gate shut when there is no forward pressure. Another example is the backwater valve (for sanitary drainage system) that protects against flooding caused by return flow of sewage waters. Such risk occurs most often in sanitary drainage systems connected to combined sewerage systems and in rainwater drainage systems. It may be caused by intense rainfall, thaw or flood.
A stop-check valve is a check valve with override control to stop flow regardless of flow direction or pressure. In addition to closing in response to backflow or insufficient forward pressure (normal check-valve behavior), it can also be deliberately shut by an external mechanism, thereby preventing any flow regardless of forward pressure.
A lift-check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.
An in-line check valve is a check valve similar to the lift check valve. However, this valve generally has a spring that will 'lift' when there is pressure on the upstream side of the valve. The pressure needed on the upstream side of the valve to overcome the spring tension is called the 'cracking pressure'. When the pressure going through the valve goes below the cracking pressure, the spring will close the valve to prevent back-flow in the process.
A duckbill valve is a check valve in which flow proceeds through a soft tube that protrudes into the downstream side. Back-pressure collapses this tube, cutting off flow.
A pneumatic non-return valve.
Multiple check valves can be connected in series. For example, a double check valve is often used as a backflow prevention device to keep potentially contaminated water from siphoning back into municipal water supply lines. There are also double ball check valves in which there are two ball/seat combinations sequentially in the same body to ensure positive leak-tight shutoff when blocking reverse flow; and piston check valves, wafer check valves, and ball-and-cone check valves.
