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.

4.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:How big valves are used in a DN159 pipe?
Nominal diameter DN150 corresponds to the outer diameter of De159To say DN159 is wrong, because DN is the nominal diameter (diameter in the middle of the tube wall)De159 refers to the outside diameter (outside the diameter of the wall)DN39 should be DN32. Nominal diameter 32, outer diameter 39.
Q:Signal butterfly valve installation or other valve installation
The installation of the signal valve is in accordance with GB50261-2005The 5.4.6 signal valve shall be installed on the pipe in front of the flow indicator, and shall not be less than 300mm from the flow indicator.The other valve control valve installation, specification, type and location of installation shall comply with the design requirements, the installation direction should be correct, control valve should be clean, no blockage, no leakage; the main control valve should be added headstock logo, the control valve cover shall be provided to indicate position of the mark in the position.1. The installation of the exhaust valve shall be carried out after the pressure test and the flushing of the system pipe. The exhaust valve shall be installed at the top of the water distribution dry pipe and the end of the distribution pipe, and no leakage shall be ensured.2, the valve flow direction should be consistent with the direction of flow in the water supply pipe, water inlet side of the filter is installed, and should be installed in the control valve; the adjustable valve should be installed horizontally, the valve cover should be upward; the proportional valve should be installed vertically: when the level of installation, the valve orifice hole single breath we should double down, breathing valve whose orifice should be in a horizontal position.3 other control valve should be installed to keep a certain distance, to facilitate maintenance and management, installation of multifunctional pump control valve itself with pressure gauge, pressure gauge should be installed in the adjacent parts; import should be prevented in the back before the installation or use of the filter with filter backflow preventer, backflow preventer at both ends the valve should be installed separately, and at least one end of the flexible joint should be installed;
Q:Where is the Hefei valve market?
On the valve network to find the best, you can find the valve business in Anhui
Q:What are mine valves?
In fact, much, no matter what the industry, with many types of valves. You want to see what works on the use of what media, in the choice of what type of valve is more appropriate.
Q:What is valve packing used for?
Main stem to prevent leakage, there are PTFE and graphite and so on. There are no other good products to replace.
Q:I want to act as a proxy valve
Many of them are now in Fujian valve valve agent many manufacturers are now seeking cooperation in the valve and pump after all or many different places to the other industries also need a process to proxy depends on your targeted customer base is better than the brand also has the advantage of brand price comparison
Q:Pump, valve, these belong to the material?
In the stainless steel industry category: sheet only belongs to the material! In the mechanical and electrical equipment categories: valves in the screws, gaskets, nuts are materials! This is relative!
Q:What's the sewage treatment valve with?
Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective.
Q:What is the term "Z41H-16C" on the line?
The ram of the Z41H-16C is linear with the stem, called (also known as the bar gate valve). Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust.
Q:Is the heat jacketed valve fitted with flanged flanges?
Insulation valve is the standard valve, just in order to ensure the link bolt flange to super space, usually a large ball than normal level, such as the use of the path is DN80 flange, flange is DN100, so is the standard, but the size of flange connecting with other valves are not the same.
