What is the basic structure of Manifold Block hydraulic valve and how much is the machining accuracy of the screw hole? Next, Shandong hydraulic valve manufacturers and we have a brief introduction.

 

Manifold Block hydraulic valve is an automatic component commonly used in industry by pressure control in operation. In the process of operation, its equipment is mainly controlled by internal pressure oil. In use, it can be used to control the water and electricity pipeline at a distance by cooperating with the pressure distribution valve.

The basic structure of Manifold Block hydraulic valve includes the valve core, the valve body and the control device that drives the valve core to do relative movement in the valve body. The main forms of the valve core are slide valve, cone valve and ball valve. In addition to the valve body hole or valve seat hole with the valve core, there are external tubing inlet, outlet and outlet.

 

The device that drives the valve core to do relative movement in the valve body can be a hand regulating mechanism, or a spring or electromagnet, and some occasions also use hydraulic pressure drive. In principle of operation, hydraulic valve is the use of the relative movement of the spool in the valve body to control the size of the valve port on and off and the opening, in order to achieve pressure, flow and direction control.

The Manifold block hydraulic valve block is best made of 35 forged steel, and the general valve block is made of A3 steel or ductile iron. Enough machining allowance should be left when cutting the valve block material from the plate by gas cutting, and the blank of the valve block should be forged and then processed. The material for processing the valve block shall ensure the internal structure is dense, and shall not have any defects such as interlayer and tracoma. If necessary, the blank shall be tested.

 

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 screw holes on Manifold Block hydraulic valve should be required for machining accuracy. Generally, 7h will be selected. 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. The surface roughness of groove of type 0 ring is Ra3.2, and that of general channel is Ra12.5.

 

The above is the sharing of the structure and screw hole accuracy of the hydraulic valve brought by the Manifold Block hydraulic valve manufacturer. To know more about the Manifold Block hydraulic valve, please pay attention to the official website of our company.
