Q: What is the difference between the copper gate valve and the ordinary material gate valve?!: The material of general gate valve is cast iron, and the copper gate valve should be used in special requirement.

Q: The difference between flanged gate valve and common gate valve: Flange valve: English name; Flange Gate Valve is the gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface to form a wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52'. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate.Ordinary gate valve: mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Gate valve applies to pressure, temperature and caliber range is great, especially for medium, large diameter pipesThe most important difference: flange gate valve and ordinary gate valve is different, flange gate valve quality, durable, easy to install, but higher prices, generally used for large pipelines. Ordinary gate valves are used for small caliber, easy to change places.

Q: Why is gate valve or butterfly valve used for water pump?: General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment

Q: What kind of gate valve is Z6CS-H102?: Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr

Q: Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?: In the standard JB/T5296-1991 "universal valve flow coefficient and the flow resistance coefficient test method",

Q: What is the allowable leakage rate of the gate valve D?: In GB/T 13927, the leakage rate of the valve is divided into 10 grades, namely: A, AA, B, C, CC, D, E, EE, F, G class. And stipulates that when the order contract does not specify, the metal sealing valve according to D requirements.

Q: What is the difference between gate valve and gate valve? Is it the same valve?: The same, very few people call gate valve, all call gate valve.

Q: Which is the most expensive, check valve and gate valve?: In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124

Q: Notes on flat gate valves: internal structureThe 1 seat O ring seal and preload floating seat structure, so that import and export of two-way valve seal plate; and the structure of the normal valve opening and closing torque only 1/2, can easily open and close valves2. when fully open, the channel is smooth and straight, the flow resistance coefficient is extremely small, and there is no pressure loss. The pipeline can be cleaned through the hair bulb3 the packing structure with the ability of self sealing, without frequent adjustment, opening and closing very lightweight, and reliable seal, the stuffing box is arranged at the auxiliary seal oil into the structure, absolutely reliable sealing performance, thereby achieving zero leakage; solve the shortcomings of the general valve packing leakage of the most vulnerable4., when the flat gate valve is closed, it can automatically unload the inner cavity high pressure, and ensure the safe use5., fully enclosed structure, good protection performance, can adapt to all-weather requirements6., the valve seat sealing structure should be elastic, preload, upper and lower sealing seat at the same time sealed structure. The valve seat and the seal are always face to face sealed.The 7. seat has self-cleaning function and is free of direct airflow during valve opening or closing. The seat shall be made of lubricated, non wearing material.8. valve actuator failure will not affect the other parts of the valve, maintenance and replacement work can be carried out without removing the valve.9. yoke sleeve aluminum bronze yoke sleeve with pin type thrust bearing to minimize operation torque.10. stem - thread length until bracket; dowel and spot welding; stability.11. pressure seal - simple construction, with sectional retaining rings and silver plated low carbon steel gaskets, helps to remove and achieve the best bonnet seal.12. seat ring - welded seat ring is perpendicular to the flow channel and is easy to maintain.

Q: What does "Z45W-10T" mean?What does each letter stand for?: W is the seal material or lining material code, the valve sealing material is the valve body material, the valve sealing surface material code with "W" said, here stands for brass;The 10 is the pressure code, which stands for PN10, which is often called 1.0MPa;
