High-pressure material angle valve with turbulence blades

Abstract

The invention relates to a high-pressure material angle valve with turbulence blades, which comprises a valve body of the angle valve, wherein the valve body of the angle valve is right angle type, a valve seat is arranged at an outlet of the valve body of the angle valve, and a valve core is mounted in the valve seat; a valve rod is mounted in the valve body of the angle valve, the valve rod and the valve core constitute an integrated structure, and the top end of the valve rod penetrates out of the valve body of the angle valve; and the high-pressure material angle valve is characterized in that the turbulence blades are arranged on the wall of an inner cavity of the valve body of the angle valve. The turbulence blades are respectively arranged on the wall of the inner cavity which is just opposite to an inlet of the valve body of the angle valve, the wall of the inner cavity on the left side surface and the wall of the inner cavity on the right side surface. A sealing gasket is utilized for sealing between the valve seat and the outlet of the valve body of the angle valve. The high-pressure material angle valve has the advantages of simple structure, safety and reliability, and can greatly reduce the production cost.

Description

technical field

[0001] The invention relates to a high-pressure material angle valve, in particular to a high-pressure material angle valve with spoiler blades. Background technique

[0002] With the continuous improvement of the domestic industrial automation level, the control valve, as the most commonly used and most important terminal control element in process control, has a very fast overall development speed, but the development speed of material angle valves for harsh working conditions such as high temperature and high pressure difference However, it is relatively slow. Most of the internal parts of high-pressure material angle valves are severely worn due to the erosion of high-speed medium flow, which greatly reduces the service life of the product and brings huge economic losses. At present, the pressure reduction and noise reduction methods commonly used for high-pressure material angle valves generally adopt the installation of throttle sleeves, labyrinth group...
