FAQ

What is the wedge type gate valve wedge is what mean

According to the gate can be divided into the form of parallel wedge type. (1) wedge type gate. Wedge type gate the sealing surface of a certain angle with the vertical center line of the gate, the size of angle depends on the medium temperature and diameter size. General medium temperature is higher, and the greater the inclination angle is bigger, in order to prevent the temperature change when the gate is stuck, unable to open. Wedge gate sealing than the parallel well.

Internal screw current limiting gate valve (Tan Gang) PN5.0 DN15/ Phi 1 Rc1/2 what does that mean?

We did thatInternal thread current limiting gate valve (Tan Gang)Body material: carbon steelPressure rating: PN5.0 = 300LB American StandardNominal = DN15 = 1/2"Phi 1 = in the middle of the gate drilling a Phi 1 hole, so that in closing there will be a certain flow, that is, the minimum flow, that is, the current limit.Rc1/2 is thread, which is the connection

What's the difference between open rod gate and dark rod gate valve?

There are several differences between the open bar gate valve and the dark rod gate valve:1, the bright bar gate valve can see the screw rod, but the dark rod can not see the lead screw;2, clear shot valve is threaded through the drive rod and the steering wheel to raise or lower the valve; dark rod valve in the switch when the steering wheel is connected with the valve stem is relatively fixed, it is through the stem of a fixed point in the rotation to drive the valve to move up and down to complete the opening and closing of the;Drive screw

P work pressureP54 temperature at 540 degrees of work pressureThe pressure at P54 100 is 540 at the temperature of 100barV valve for chromium molybdenum vanadium steelP54 pressure 140V temperature at 540 DEG C for 140bar valve for chromium molybdenum vanadium steelP54 pressure 170V temperature at 540 DEG C for 170bar valve for chromium molybdenum vanadium steelFrom the JB/T4018 "valve type model preparation method"The standard unit is MPa, but it is usually used in bar

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

The main question is, what are the functional differences in which case?

The gate (gate valve) is a 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 valve. The 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 valve advantages: 1, fluid resistance is small,.2, opening and closing more labor-saving,.3, medium flow unrestricted, not disturbed flow, do not reduce pressure,.4, simple shape, structural length is short, manufacturing process is good, a wide range of applicationsValve shortcomings: 1, between the sealing surface is easy to cause erosion and abrasions, maintenance is more difficult,.2, big size, open need some space, opening and closing time is long,.3, the structure is more complex

What kind of valve is gate valve? Is it different from the cut-off valve?

Gate valve is applied to the big diameter pipeline valve, the valve is generally used in small pipe diameter pipeline, their internal structure is different, the valve can not regulate the flow of water, the valve can be. If you want to understand in detail, it is recommended to take a sample of valve manufacturers to see the internal structure.
