1.Structure of  Ball Valve Description

Threaded ball valve is closed is a ball, ball around the center line of the body as a rotation to achieve a kind of open and close the valve.
Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium. Two type ball valve, three type ball valve, is widely used in recent years a new type of valve, the valve average installation. And ball valve is a kind of ball valves, threaded pipe connection is screwed connection, and flanged ball valves, welded ball valve, etc.

2. Main Features of the Ball Valve

• Small flow resistance;

•  Simple structure

• Small volume, light weigh

• Small volume, light weigh

•  Easy to operate, open and close quickly, facilitate remote contro

• Easy maintenance, sealing ring, which generally remove easy to change

• Full open or full close, sphere and valve seat sealing surface and the dielectric isolation, medium through does not cause the valve sealing surface erosion.

5.FAQ

1. What's are the characteristics of ball valve?

The distinct feature of a ball valve is the sealing surfaces between the gate and seats are planar, so ball valves are often used when a straight-line flow of fluid and minimum restriction is desired. The ball valve faces can form a wedge shape or they can be parallel. 

2. What is the work principle of ball valve

 The ball valve faces can form a wedge shape or they can be parallel. Ball valves are primarily used to permit or prevent the flow of liquids, but typical ball valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, ball valves are often used in the petroleum industry. 

3.  What is the structure?

Bonnets provide leakproof closure for the valve body. Ball 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: I would like to ask how the valve entry, for a new pair, really difficult, what cutaway view, there are other, just contact the valve less than a week, and sometimes it is really difficult to understand. Forget the experienced teacher can be generous with your criticism to later, indebted forever, learn the valve Comrades some help.In a company CAD to relatives as soon as possible to a company, and then slowly improve, I do not know what is the request of the novice, and how to start as soon as possible, I am learning routine is: give me a set of valve design drawings, and then I paint it on, do not understand the structure and workshop look. I wonder if you have any good learning methods that can be referred to and supplemented by younger brother
Valve range can be very wide, each company to do valve products are not the same;According to the company's production capacity and technology,Valve parameters to:1, valve spool material,2, connection mode (thread, welding, flange, clamp, socket welding, fast loading, etc.),3 caliber,4, medium (water, steam, oil, gas, liquid, etc.),5, temperature (medium temperature, environmental temperature),6, pressure (MPa, LB, K, etc.),7, configuration (executor and its accessories);A lot of valve requirements and this almost. Can also be selected according to the ideal valve function of customers.Switching type:Ball valve, butterfly valve, globe valve, gate valve, needle valve, etc.Regulatory type:Pneumatic valve, electric valve (adjustable type can be divided into: regulating temperature, regulating pressure, regulating flow), and so on
Q: What kind of valve is it? How do you see the status of the switch?
Globe valve, not ball valveClockwise (Bell) needle to reduce the flow to the end of the shutdown, the counter clockwise to open. You can turn the multi circle plate will also lift up and down. The spindle, to the top is open, down to the edge off.The ball valve has a strip handle, the line is connected, and the cross is turned off
Q: What is the difference between the valve before the pump and the valve after the pump?
Pump in front of the gate valve + one-way valve, after the pump connected valve, so that in the regulation can be clearly aware of the actual pump lift is large, without the impact of system pressure.Valve is the general name of pumps and valves.A valve that is not used in a pump or with a pump.Pump and valve are often associated with the use of the occasion. In other words, where there is a pump, there is usually a valve, where a valve is often required. They are all used for liquid delivery.
Q: What does the valve specification "3/4CL150" mean?
3/4 is the caliber, that is, DN20, CL150 is the pound, American Standard, and Kg is 16-20Kg.
Q: What does the RF of the valve mean?
The flange flange can be applied to the HG/T flange standard, or any other flange standard. HG/T will be more detailed
Q: How to check if the gas valve is open?
Method 1: gas valve has a handle, the handle is parallel to the pipe, that is open, vertical is closed. If there is no handle, there is a rectangular main handle on the valve, the handle is parallel to the pipe, that is, the open state, vertical is closed.Method two: the valve handle and pipe to "one" word proved to come, into "ten" word is off. Also, turn the handle clockwise and turn counterclockwise.
Q: What should be checked before using the valve?
The valve must be visually checked before installation1, valve opening and closing position should meet the following requirementsThe valve, the cut-off valve, throttle valve, regulating valve, butterfly valve, foot valve, the valve is in full closed positionPlug valves and ball valves should be in full open position? diaphragm valve should be in the closed position, and can not be too tight to prevent damage to the diaphragmCheck valves shall be closed and secured2, the valve shall not be damaged, missing parts, corrosion, nameplate shedding and other phenomena, and the valve body shall not be dirty3, both ends of the valve should be protected. Handle or handwheel should be flexible and light, and must not be stuck4, valve body casting, the surface should be smooth, no cracks, blisters, lock, pores, burrs and other defects; outside valve forging, the surface should be free of cracks, interlayer, double skin, scar defect
Q: What does the ZH41 valve ZH41 mean, and what other specifications?
Is the model wrong? The correct one should be Z41HGate valve, hand flange connection name, rod type single gate, sealing surface is alloy steel
Q: How to carry out the valve strength test and air tightness test?
All the factory must go through the valve pressure test, strength test for 1.5 times the nominal pressure, closed at both ends of the valve import and export, fully open the valve test pressure for 1 - 5 minutes, see the specific situation, also called low pressure seal test seal test pressure seal test, 0.6MPa. Also 1.1 times the seal hydrostatic test, specific, you see, JB/T9092 standard, very detailed
