1.Structure of Gate Valve Description：
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. 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：
The sealing surface of valve seat and gate is overlaid (surfaced) with hard alloy, resistant to corrosion and abrasion.
Valve seat, gate and stem are sealed with imported lip-shaped combined seal structure, so they are safe and reliable, and the switching torque of valves is low.
Simple and safe design of valve gate and seat, makes it easy to change without special tools.
Non-rubber seal effectively protects valve chamber from mud, sand and rock, etc.
Stem sealing can be changed under pressure.
Stem is designed to be rising stem and non-rising stem, with a clear sign for valve opening.
Drive mode falls into manual, hydraulic and gear.
Combining type falls into flange, thread and hub.

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 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: Remove the handle and lever the stem rotation with a wrench,
- First you know what valve you need, or you know where to use the pipe material, so you do not need to understand the valve material.
- Q: What's the valve specification DN20?
- It's not clear what you want to ask
- Q: How about the valve?
- The British Hudson Valve Co. Ltd. (HUDDERSFIELD VALVES LIMITED), founded in 1964, its predecessor for the British metal parts company (ART METAL FABRICATION LTD AMF, referred to as LTD), located in the world famous one of the UK's Huddersfield valve production center (HUDDERSFIELD), the main production of various kinds of valve, valve cage valve and other valve manufacturers supporting. .
- Q: Where is the hydrant main valve?
- The fire hydrant generally has two sources, one is from the roof water tank, a water pump is from the housing, maintenance, should close the fire hydrant located on the riser inlet valve tube under the ring, generally located in the top and bottom, and then discharge, when the valve cannot be closed, the proposed closure of replenishment valve and the pressure stabilizing device of water tank, fire pump in manual state, drainage after maintenance. Watch out for fire.
- Q: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?
- Now the UF system is basically full automatic system, that is to choose automatic valve. As for the pneumatic valve or electric valve, depending on your investment and the scene.
- Q: How to quickly identify the types of valves?
- The "Practical Handbook" valve design on the valve structure, with precision, surface roughness and typical design standard, the valve has hundreds of models, and continue to have a new valve, see a written one, is shorthand.Valves: valves (Valve) control the flow of fluid medium flow, flow, pressure, temperature and other mechanical devices, valves are the basic components of the pipe system. Valve fittings are technically similar to pumps and are often discussed as a separate category. Valves can be operated by hand or hand wheel, handle or pedal, or by control to change the pressure, temperature and flow change of fluid medium. The valve can perform continuous or repeated operations on these changes, such as a safety valve installed in a hot water or steam boiler. In more complex control systems, automatic control valves are required depending on external inputs (i.e., regulating the flow through the pipe to the changing setting points). Automatic control valve without manual operation, according to its input and settings, so that the valve accurately control the requirements of fluid medium. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
- Q: How do I open the gas valve?
- Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all. 1, according to the routine, now the handle position shows that the valve is open. 2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
- Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?
- High pressure bypass valve DN254 * 800 belongs to bypass valve.Function of bypass systemThe turbine by-pass device mainly has three functions of starting and overflowing:1 in the cold, warm and hot, the bypass system can realize the optimal unit start-up and shut-down in turbine operating conditions, start and stop curve can meet the requirements, two types of automatic and manual operation, with the establishment of the boiler steam temperature and steam turbine components. To shorten the start-up time.2. when the turbine is tripped, the bypass system can operate at a high speed and reach full open position.3., when the turbine load changes, the by-pass system has the regulating function, and the safety valve action can be avoided and the operation stability of the boiler can be improved when the instantaneous change of the moving state.The function of the bypass control valve:The main function of steam turbine bypass system is high pressure steam adjusting throttling and superheated steam cooling. The bypass valve to perform these functions at the same time and in low noise, small vibration, valve resistance to achieve its goal of temperature and pressure loss under the condition of touch.
- Q: How do you understand the valve Z41X-16?
- This is a standard set, the landlord himself to check the JB/T308 standard, Baidu library, some, and is free to download:JB/T 308-2004 valve type method of preparation clear EditionZ = gate valve4 = connection: flange1 = structural form: open rod single gateX = sealing surface material: Rubber16 = nominal pressure: 1.6MPa16 there is no letter behind it indicates that the body is made of cast iron
- Q: someone else's home has valves, but also checked nothing, in addition to telephone repair, there are other ways? emergency
- That's a lie. Other people's homes do not necessarily have water.You need to keep on pressing the property.
