1.Structure of Gate Valve Description

A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. For extremely thick fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On opening the gate valve, the flow path is enlarged in a highly nonlinear manner with respect to percent of opening. This means that flow rate does not change evenly with stem travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be fully opened or closed.When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low friction loss.

5.FAQ

1. What's are the characteristics of gate valve?

The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel. 

2. What is the work principle of gate valve

 The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.

Q:What does valve qz45x - 10q mean?
Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
Q:Pump adapter generally includes what accessories?
Generally do not require safety valve, just install exhaust valve in individual places.
Q:What is the difference between a flanged gate valve and a wire gate valve?
This is very simple, flanged gate valve is the valve with both ends of the flange, the installation of the pipe to weld the reverse flange, bolt with the pipe flange and valve flange connection. Valve is the valve ends with wire wire, a wire and wire points, and pipeline installation, connecting part with joint or head of the screw and the valve directly on the pipe screw connection.
Q:Installation and operation instructions of knife gate valve
5., when installing the valve, users must reserve the necessary space for valve actuation;The wiring of the 6. driving device shall be carried out according to the wiring diagram;7. knife gate valve must be regularly maintained, shall not be arbitrarily collision and extrusion, so as not to affect the seal.
Q:Valve flange drawing n- up to what
A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size
Q:What's the meaning of flexible z45x-10q door valve?
Crown valve pressModel Z45X-10QZ refers to gate valve4 finger flange connection5 refers to the dark bar driveX refers to rubber seals10 refers to 10 kg pressureQ refers to the body material, ductile ironFull bore flange soft sealed gate valve
Q:Will the water supply and drainage to wear civil air defense gate valve, the use of bright rod or dark rod?
2, soft sealing gate valve at the bottom of the pit. No accumulation of slag material, valve opening and closing of the failure rate is low;
Q:What is the soft seal gate valve?
Cautions for installation and maintenance of soft sealing gate valve:For double gate valves, the direction of installation shall be in the vertical position of the valve stem, and the handwheel at the top.The installation of the soft gate valve shall be carried out in strict accordance with the installation environment, installation conditions and installation procedures on the factory manual.After installation, the soft seal gate shall be periodically checked for performance and killed in the cradle before any undesirable conditions occur.
Q:How about the model of stainless steel gate valve?
Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.
Q:Gate valve Z41H-16Q generally used for what place?
Gate valve is one of the most commonly used cut-off valve, mainly used to connect or cut off the medium in the pipeline, not applicable to regulating medium flow. Suitable for medium and large diameter pipelines.
