Product Description:

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 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:HVAC design, why is less than DN50 of pipe gate valve and cut-off valve,
Have not heard of this requirement, before the ball valve and butterfly valve quality is rarely used now are good, can be used, but not easy to control the flow valve butterfly valve can close more time-saving, fluid resistance of small. HVAC branch pipe, to flow control, so the choice of gate valve and cut-off valve is more reasonable, and now choose a ball valve is also a lot.
Q:What are the main types of gate valves?
According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;
Q:What is the difference between cut-off valve and gate valve?
Simply put, the cut-off valve is one-way, only into, do not give up, the valve is two-way
Q:The difference between flanged gate valve and common gate valve
Flange gate valve and ordinary gate valve difference is that the flange gate valve of good quality, durable and easy to install, but the price is a little high, generally used for large pipelines. Common, also available, such as small caliber, easy to change places.
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:What is the standard length of GB steel gate valve?
1, product standardsGeneral purpose valves, flanged connections, iron gate valves, GB/T 12232-2005General requirements for steel valves GB/T 12224-2005"Steel flat gate valves for pipelines" JB/T 5298-91Inspection and test of valves. JB/T 9092-1999Standard for safety evaluation of drinking water distribution equipment and protective materials GB/T 17219-1998
Q:What kind of gate valve is Z6CS-H102?
Z== valve type: gate valve6== pressure rating: 800LB, API602C== structure: bolt connection, valve cover, bolt connection gland, bright rod support typeS== connection form: socket welding, that is, SWH1== body material: A10502== inner material: seat sealing surface STL, gate sealing surface STL, valve stem 13Cr
Q:What is gate well?
Technical requirement:1: the valve itself can not seep, it must ensure its tightness;2: water supply pipeline during use, pipeline will be pressure from different aspects, which will produce different degrees of jitter or settlement, which requires the connection of water supply pipes and valves in the well to be reliable, able to adapt to a certain degree of jitter and settlement, and to prevent water infiltration into the well chamber in the pipeline valve wells; deep, slightly larger are generally made of cast iron valve (such as the cut-off valve, butterfly valve) iron valves long-term immersion in water, will affect the service life or cause fracture, so the sealing requirements are higher;3: valve shaft, shaft and well body, manhole cover way of connection should be reliable, not because of heavy rain or water seepage water into the well room.4: valve well is buried in the ground, to bear from different directions of different pressure, and different chemical substances corrosion and damage, and requirements of its pressure capacity and acid and alkali corrosion is better.
Q:What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve
Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.
