Action sensitive Action sensitive stainless steel 304 what is sluice valve ductile iron valve

Function Description:

Gate valve is a valve that the valve plate moves along the vertical direction in the pipeline

Advantages of gate valve:

1. Small fluid resistance

2. The torque for opening and closing is small, so it is easy to open and close.

3. The medium flowing direction is not restricted, and it doesn't disturb flowing and reduce the pressure of pipeline.

4. Short length structure

5. Good sealing performance

6. Simple shape, good casting process, widely used

Q: What does the "PN" mark on the valve mean?: The valve will usually be marked with "DN.PN." these two signs,DN refers to the valve path, and PN refers to the pressure levelFor example: DN25, PN16Refers to the valve diameter of 25mm valve, the pressure is 16 kg (1.6Mpa)

Q: Valve category can fill the trunk door, branch valve Mody?: Valve category refers to the type of valve, the big species are divided into: butterfly valve, gate valve, globe valve, ball valve, check valve, control valve, trap and electric valve,

Q: What is the difference between the valve before the pump and the valve after the pump?: Pump in front of the gate valve + one-way valve, after the pump connected valve, so that in the regulation can be clearly aware of the actual pump lift is large, without the impact of system pressure.Valve is the general name of pumps and valves.A valve that is not used in a pump or with a pump.Pump and valve are often associated with the use of the occasion. In other words, where there is a pump, there is usually a valve, where a valve is often required. They are all used for liquid delivery.

Q: How to quickly identify the types of valves?: You can look through shapes, signs, or buy a valve manual

Q: Which valves are used in the power station?: Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.

Q: I would like to ask commonly used water valve what kind of? What are the characteristics?: Valve is used as cut-off media, the flow through the fully open, then the pressure medium to run minimal loss. Usually does not require frequent valve for opening and closing, and maintain the gate fully open or fully closed condition. Not suitable for use as a regulator or throttle. For high-speed flow of medium, the gate conditions can cause vibration of the gate in the partial opening, and the vibration may damage gate and valve seat sealing surface, and the throttle gate will suffer erosion media. From the structural form, the main difference is that the sealing elements form. According to the form of seals, often divided into several different types of valve, such as: wedge gate valves parallel gate valve, parallel gate valve, wedge gate valve. The most commonly used form of wedge gate valve and parallel valve

Q: What does valve 41F-40C mean?: Incomplete model4 is the flange1 is the formF is seat material, fluoroplastic, ptfe,40 nominal pressure 40 kgC body material carbon steelFront also have to add valve category code, such as manual ball valve, Q41F-40C manual code is 0, but this 0 we don't write out, so only written Q41F-40C electric ball valve, Q941F-40C 9 represents electricGate valve is Z41F-40C

Q: What kind of valves are best used for sand drain valves?: Refinement of the Chinese market demand for the valve, like a Pyramid structure. Spire for all imported products, quality, precision, high prices, small amount of monopoly high-end users. The central part of the tower is a wholly foreign-owned and joint venture site, which corresponds to medium and high-end customers who require high quality valves and moderate prices. As for domestic enterprises, they are basically hovering at the bottom of the tower, vying for low-end users in the form of quantity and price. With the increasing rationalization of user purchasing behavior in China, more and more attention has been paid to brand and quality, and the products of sole proprietorship and joint ventures are becoming more and more popular. At the same time, the sole proprietorship and the joint venture enterprises have gradually eroded the market share of the imported products by improving the quality and reducing the cost.

Q: How can the material be checked by valve approach? What experiments do you need?: May refer to the valve pressure test principle and the pressure test matters needing attention.(1) in general, the valve shall not be subject to strength test, but the body and bonnet shall be subjected to strength tests after the repair of the valve body and bonnet or corrosion damage. For the relief valve, the constant pressure and seat return pressure and other tests shall be in accordance with the specifications and the relevant regulations.(2) the installation of the valve should be done for strength and tightness test. Low pressure valve sampling 20%, if not qualified should be 100% of the inspection; medium and high pressure valve should be 100% of the inspection.(3) the installation position of the valve shall be in the direction of easy inspection during the test.(4) welding connection valve, not with blind plate pressure test can be used when the cone seal or O ring seal pressure test.(5) when hydraulic test, the valve air will be excluded as much as possible.(6) the pressure should be increased gradually during the test, and the pressure will not be sudden and sudden.(7) strength test and sealed test duration is generally 2~3min, important and special valves should last 5min. Small caliber valve test time can be a little shorter, large caliber valve test time can be longer. During the test, the test time can be extended if in doubt. Strength test, does not allow the body and bonnet sweating or leakage. Sealing test, the general rotor valve only once, the safety valve, high pressure valve and other raw valve to be carried out two times. When testing for the low pressure, large diameter valve is not important and there are provisions to allow leakage of the valve, allowing a small amount of leakage; the common valve, power station valve, marine valves and other valve requirements vary on leakage requirements according to relevant regulations.
