Q:What is the difference between the cut-off valve and the gate valve?
What is the difference between gate valve and stop valve?:Gate valve and globe valve structure is different, the valve structure for hand wheel, with the stem rotating together to do the opening and closing movement. Valve structure is rotating handwheel, stem do lifting movement. The flow is different, the gate valve requires full open or full closed state, the cut-off valve does not need. The valve has the flow direction requirements, and the gate valve has no inlet and outlet requirements!Sealing performance comparison:Valve length is shorter than the cut-off valve, higher than the cut-off valve, the valve should pay attention to the installation of high elevation. The gate valve can be tightly closed with the sealing surface by the pressure of the medium so as to achieve the effect of not leaking.
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:Function of signal butterfly valve and gate valve
The signal butterfly valve applies to petroleum, chemical, food, medicine, papermaking, water and electricity, ships, water supply and drainage, smelting, energy and other system pipelines. Available in a variety of corrosive, non corrosive gases, liquids, semi fluids, and solid powders.
Q:What is gate well?
Explanation:Valve wells also called valve wells, underground pipelines and underground pipelines (such as tap water, oil, natural gas pipeline valve etc.) in order to facilitate the opening and closing part of network operation or overhaul when needed, a pit is a similar small room (or well), the valve installation in the pit where, for regular inspection, cleaning and dredging pipeline, to prevent the blockage of the pipeline project. The pit is called a well. There are valves, wells must have valves, but there is not necessarily a valve valve wells.
Q:What do you mean by gate valve type RVHX-0150-10 and Z45X-16Q?
Z45x-16q, Z means gate valve, 4 means flange connection, 5 refers to dark rod gate valve, X means rubber seal, 16 refers to nominal pressure 1.6MpaRVHX means manual gate valve, 150 refers to the caliber of DN150, and 10 indicates nominal pressure of 1.0MPa
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 the gate valve SZ45X-1.0 stand for?
Z- stands for gate valves, 4 for flange connections, 5 for wedge wedge single gate, X for rubber seals, and 1.0- for PN1.0MP
Q:Analysis of the advantages of elastic seat sealing gate valve?
General valve on the market for a long time there is Water Leakage or rusting, overcome the valve seal bad, rust and other defects, using the elastic elastic valve seat seal gate produce small quantities of elastic deformation of the compensation function to achieve a good sealing effect, with a switch to lighter and reliable sealing, good elastic memory and life and other significant advantages. The utility model can be widely used as an adjusting and intercepting device for pipelines such as water supply, sewage, building, petroleum, chemical industry, food, medicine, light industry, electric power, ship, metallurgy, energy system, etc.. This is the advantage and advantage of an elastic seat seal gate valve.
Q:What is the difference between a flanged gate valve and a wire gate valve?
Threaded valve is via the wire or wire is connected with the pipeline, a small general air for the air valve, all belong to this
Q:What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
