Valve is a opening and closing the gate assembly, perpendicular to the direction of movement and direction of flow of the gate, gate valve can be fully open and fully closed, discomfort door parameter varies, usually 5 degrees, the medium temperature is not high for 2 ~ 52 '. Improve the process, make up the sealing surface angle in the process of the deviation, which is called the gate.
Motion editing valve closed, the sealing surface can only rely on media pressure to seal, which only rely on media Z41h flange wedge gate valve pressure on the sealing surface of the disc to the other side of the valve seat to ensure the sealing surface, which is self sealing.
Most of the valve is forced to seal, that is, when the valve is closed, to rely on external force to force the gate to the seat, in order to ensure the sealing surface of the seal.
Movement: gate valve with the valve stem together for a straight line movement, also known as the gate valve.
Usually on the lifting rod with trapezoidal thread, through the valve on the top of the nut and the body of the guide slot, the rotating motion into a linear motion, that is, the operating torque into the operating thrust.
When the valve is opened, when the gate height is equal to 1:1 times the diameter of the valve, the fluid passage is completely free, but at the time of operation, the position can not be monitored.
Actual use, is the apex of the stem as a sign, that is, the open position, as its fully open position. In order to consider temperature changes occur locked phenomenon, usually open to the vertex position, and then rewind 1 / 2-1 circle, as a fully open valve position.
Therefore, the valve fully open position, according to the location of the gate (that is, the stroke.
Some gate valve stem nut is located on the gate, the hand wheel rotation to drive the valve stem rotation, and so that the gate to upgrade, this valve is called the rotating rod gate valve or called the dark bar gate valve.

- Q:The difference between cut-off valve and gate valve
- Structurally, the gate valve for the gate, down to the front and back seat seal; globe valve with spherical, taper and flat spool, down to the valve seat seal. Functional stop valves are generally used for pressure flow control. Gate valves are used for isolation.
- 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:The difference and use of gate valve and stop valve
- Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.
- Q:What is the size and length of the DN80 gate valve? 10 kg and 16 kg, respectively?
- Valve structure length standards are PN16, short series for 203mm, long series for 280mm, flange size by PN16.
- Q:Generally, how big is the diameter of the installation flange plate gate valve?
- Under normal circumstances:Flanged gate valves for piping over DN50,DN50 (below) can be made of wire or gate valves, or flanged gate valves (flanged valves or welded gate valves)
- Q: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
- Q:What are the working principles of the electric gate valve?
- We see you what type of electric valve, is integral or ordinary type, if the overall type Denso took power on the line, is generally 380V and 220V power supply, and then according to their own needs and then open the signal line, in place and closing in place and remote control line, valve position feedback signal the commonly used 4~20ma over torque protection fault signal.
- Q: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
- Q:What is the difference between gate valve 41h-16c and 41w-16p?
- The difference between 41h-16c and 41w-16p is that the material of the valve body and the material of the sealing surface are different.According to the provisions of the JB/T 308-2004 valve type programming method:H== sealing surface material: Cr13 stainless steelC== body material: carbon steelW== sealing surface material: body, that is, with the same material bodyP== body material: chrome nickel stainless steel
- Q:Yes, soft sealing gate valve can reach 25 kilograms, Fujian light valve company has this type of soft sealing gate valveAnonymous browsing | 28 times
- Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.
