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.

 

2. Main Features of the Gate Valve:

• Valve body cavity using non-toxic epoxy resin,both inside and outside flashboard completely is coated with rubber

•  Free of water pollution

• High manufacturing accuracy

• High strength

• Environmental protection and energy saving

• Good visual effect

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 is the difference between Z41X gate valve and Z45X gate valve?
There is no difference in function. The two models are mainly made of different sealing materials,
Q:What does gate z41t-10 150 mean?
According to JB/T308-2004 "valve type programming method"Z gate valve4 flange connection1 Ming wedge single gateT sealing cover material is copper alloy10 nominal pressure PN10PN16 below no marked valve body code, body material is gray cast iron150 nominal size DN150
Q:What are the working principles of the electric gate valve?
Ordinary type electric valve should be equipped with the control box, the motor is the true story and the inversion, and in general to a trip signal signal is normally open and normally closed, closed in place are normally open and normally closed two points according to their own needs wiring, three lines and then open and close control of the line of control there are also 4 lines to control some manufacturers, as well as the valve position, some three lines connected with the potentiometer, some installed valve position transmitter is connected with two lines, and over torque protection fault signal.
Q:Please tell the specific specifications and specifications of the gate valve and advise the principle of management cooperation Thank you

Q:What's the difference between open rod gate and dark rod gate valve?
3, dark rod valve is located inside of the body, in the process of opening and closing, stem only rotation move, the gate in the valve body lifting; the valve stem rod driven gate valve with the valve stem of the lifting drive thread in the external body, according to the direction of movement of the stem and the position of judge the gate opening and closing and position;
Q:What is a protective gate valve? What is gate valve knowledge?
Explosion-proof valve products, is a kind of safety valve can eliminate the shock wave which can stop the water hammer shock wave, it is a product composed of multiple sets of safety,
Q:What's the meaning of the gate valve model z41x 16Q?
According to the provisions of the JB/T 308-2004 valve type programming method:Z = gate valve4 = flange connection1 = structural form: wedge type single gateX = sealing surface material: Rubber16== pressure rating: 1.6MPaQ== body material: ductile iron
Q:What are the meaning of the cast rigid gate valves z41h-16c?
According to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== flange connection1== rigid single gateH== sealing surface material: Cr13 stainless steel16== pressure rating: 1.6MPaC== body material: carbon steel
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?
the valve before the pressure measuring point, distance of valve straight pipe length is 5 times the diameter of the valve after the pressure valve, the distance is 10 times the diameter of straight pipe length.
Q:What is the difference between gate valve and gate valve? Is it the same valve?
Gate valve and gate valve are 2 kinds of valves, do not feel like a long name is the same kind, please look at Baidu maps introduced manufacturers.
