Problems solved by technology
[0002] When adjusting the pressure of the ultra-high pressure hydraulic end, it is usually necessary to adjust the pressure within the range of 0-150MPa. The pressure adjustment is controlled by a pressure regulating valve. There are errors in the manufacturing of the valve core. Under the same pressure, the opening size of the valve core and the valve seat will be different. With this pressure regulating structure using springs, the valve core will jump when the pressure regulating valve is in use, so that the plunger Pump has flow pulsation

The invention provides a 150 MPa ultrahigh pressure fluid pressure regulating valve, and belongs to the technical field of high pressure fluid end pressure regulating. The 150 MPa ultrahigh pressure fluid pressure regulating valve comprises a valve body, a valve seat is arranged in the valve body, a water return connector is spirally connected to the bottom of the valve body, a valve element inserted into the valve seat is arranged in the valve body, the bottom of the valve element is inserted into the valve seat, the bottom of the valve element is a taper face, and a pressure regulating nut is spirally connected to the top of the valve body and is pressed to the top of the valve element. According to the pressure regulating nut, the positions of the valve element and the valve seat are fixed unchanged, and plunger pump pulsation caused by bouncing of the valve element after pressure regulation can be prevented.
Description
technical field [0001] The invention belongs to the technical field of pressure regulation at a high pressure hydraulic end, and relates to a 150MPa ultrahigh pressure fluid pressure regulating valve. Background technique [0002] When adjusting the pressure of the ultra-high pressure hydraulic end, it is usually necessary to adjust the pressure within the range of 0-150MPa. The pressure adjustment is controlled by a pressure regulating valve. There are errors in the manufacturing of the valve core. Under the same pressure, the opening size of the valve core and the valve seat will be different. With this pressure regulating structure using springs, the valve core will jump when the pressure regulating valve is in use, so that the plunger Pump has flow pulsation. Contents of the invention [0003] The object of the present invention is to provide a 150MPa ultra-high pressure fluid pressure regulating valve to solve the above problems. [0004] In order to achieve the abo...
