Manifold Block hydraulic valve: what are the characteristics of ball valve

 

Manifold Block hydraulic valve: ball valve is mainly used to cut off, distribute and change the flow direction of pipeline intermediate. It only needs to be rotated 90 degrees, the rotation torque is small, can close tightly. What aspects of the characteristics of the ball valve, today Jinan Longli hydraulic small make up with you to understand:

 

1. The sealing parts with the lowest flow resistance can withstand the high pressure difference when sealing.

 

2.. Spherical blinds in position can be automatically positioned for the working medium on both sides indeed seal.

 

3. In the larger pressure and temperature range, can achieve 100% seal.

 

4. It can achieve super fast opening and closing, some structures of the opening and closing time is very short, so as to ensure that it can be used in the automation system of the test bed.

 

5. When the valve is fully open and closed, the sealing face of the ball and seat is isolated from the medium, so the medium passing through the valve at high speed will not cause corrosion of the sealing face.

 

6. Body is symmetrical, especially by welding body construction, can withstand the stress from piping.

 

7. Compact structure, light weight, suitable for low temperature medium system of the most reasonable valve structure.

 

8. Does not get stuck without lubricants and can be reliably applied to corrosive media and low boiling liquids.

 

The above is the information sharing brought by Manifold Block hydraulic valve manufacturers, to learn more about the introduction of relevant knowledge, welcome to pay attention to our official website.

 

Installation of Manifold Block hydraulic valve and pressure regulation

 

Today, the manufacturers of Manifold Block hydraulic valve have a look at the installation and pressure regulation of Manifold Block hydraulic valve with you.

 

Manifold block hydraulic valve

 

Manifold Block hydraulic valve is an automatic component operated by pressure oil in the process of use. The whole product is controlled by pressure valve oil. In the process of use, it is usually used in combination with electromagnetic pressure valve. When in use, it can be used for remote control of oil, gas and water pipe system of hydropower station. Often used for clamping, control, lubrication and other oil circuit. There are straight moving type and leading type of points, multi-purpose leading type.

 

Manifold block hydraulic valve is mainly used to control the flow direction of oil in the hydraulic system or to regulate the pressure and flow, so it can be effectively divided into pressure valve, flow valve and direction valve. In use, a valve with the same shape can have different functions due to different mechanisms of action.

 

The flow valve and pressure valve of Manifold block hydraulic valve control the pressure and flow of the system by the throttling action of the flow section, and the direction valve controls the flow direction of the oil by the replacement of the flow channel. That said, although there are a variety of different types of hydraulic valves, they still maintain some basic points in common.

 

The surface roughness of valve and flange installed on Manifold block hydraulic valve block should reach Ra0.4, and the surface roughness of sealing surface of end pipe joint should reach Ra3.2. In addition, the perpendicularity allowance between the screw hole where the pipe joint is installed and its outer fitting surface shall be at least grade 8.

 

All the valve blocks of Manifold Block hydraulic valve fail to meet the requirements of machining accuracy, and 7H is generally selected in use. The machining accuracy of mounting holes of threaded cartridge valve should meet the requirements of product samples, and the roughness of mounting holes of cartridge valve is Ra0.8. In addition, there are also dimensional tolerance and shape tolerance requirements. The surface roughness of groove of type 0 ring is Ra3.2, and that of general channel is Ra12.5.
