Q: What is a lift rod valve?: Lever valve stem nut in the valve plate, it with the disc (hand wheel) to open the turn, its stem pull the valve head and higher than the valve disk, also known as the bar valve. It is different from the dark rod valve, dark rod valve stem nut in the valve body, when the disc rotates, the stem will not rise.

Q: The difference between fire general valve and fire fighting special valve: Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.

Q: the valve to an electrical signal, with this signal to control other components, ask: what valve?: Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation

Q: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?: The difference between the three is as follows: pneumatic valve]: driven by compressed air valve. Operation principle: the pneumatic control valve is composed of actuating mechanism and regulating mechanism. The actuating mechanism is a thrust component of the regulating valve, which generates the corresponding thrust according to the pressure of the control signal, and drives the regulating mechanism to move. The valve body is the regulating component of the pneumatic control valve. It contacts the regulating medium directly and regulates the flow of the fluid. [hydraulic valve]: the use of oil and other liquid pressure driven valve. The working principle of the hydraulic valve control valve pressure control valve flow control valve control valve control valve to control the direction of hydraulic system oil flow direction or liquid flow through the valve two, the working principle of the valve core and the valve body and valve off valve two-way hydraulic lock check valve to make oil movement off or on, changing the direction of the oil flow, so as to realize the hydraulic actuator and its driving mechanism of starting and stopping or changing the direction of movement. [electric valve]: with electric actuators to control the valve, so as to achieve the valve opening and closing. The utility model can be divided into two parts, the upper part of which is an electric executor, and the lower half of which is a valve. Also called air conditioning valve. The electric valve is usually connected by the electric actuator and the valve, and it becomes an electric valve after installation and debugging. The electric valve uses the electric energy as the power to switch on the electric actuator to drive the valve and realize the valve switching and regulating action. So as to achieve the purpose of switching or regulating the pipeline medium.

Q: What courses in the University involve valves?: Fluid mechanics, "material mechanics", "mechanical design" and other courses on the design of the valve are helpful.

Q: How to check the quality of the valve?: First, visual inspection of the valve appearance, followed by a spectrometer to check the material, material, and then look at the hydraulic test pressure, whether there is leakage.

Q: What does "DN15" mean? What does "PN 16" mean?: DN15 refers to the diameter of the valve, that is to connect the caliber of the pipe.PN16 means pressure, that is, 16 kilograms (1.6MPa).

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.
