Embodiment 1

[0011] Such as figure 1 As shown, the pressure-adjustable pressure relief valve of this embodiment includes a valve body 2 with one end closed and the other end provided with a water inlet 1. The side wall of the valve body 2 is provided with three pressure relief ports 3, 4, 5, The closed end of the valve body 2 is provided with a spring 6 and a valve core 7, one end of the spring 6 is against the inner wall of the end of the valve body 2, and the other end is against the valve core 7; the key is that the pressure relief port 3 has multiple , the pressure relief port 3 is fitted with a leakage prevention bolt 8 through thread fit.

[0012] The plurality of pressure relief ports 3 are arranged in a straight line, and the length of the valve core 7 is less than the distance between any two adjacent pressure relief ports 3, so that the valve core 7 can only open the pressure relief port each time during the moving process One of 3, 4, 5, so the relief pressure is easier to cont...

Abstract

The object of the invention is to provide a pressure-adjustable pressure release valve to enlarge the application scope of the pressure release valve. The pressure-adjustable pressure release valve comprises a valve body with one closed end and one water inlet at the other end, the side wall of the valve body is provided with pressure release ports, the closed end of the valve body is provide with a spring and a valve core, one end of the spring is butted against the end portion of the inner wall of the valve body, and the other end of spring is butted against the valve core. The pressure release valve is characterized in that a plurality of pressure release ports are arranged to match with the release resistive bolt through the screw thread. During use, the inlet pressure can push the valve core to overcome the force of the spring to move towards the closed end of the valve body without confronting the pressure release ports, so that the liquid in the inlet can be released from the pressure release ports to achieve the purpose of the pressure releasing. The distances between the pressure release ports and the closed end of the valve body are different due to the different positions of the pressure release ports, so that users can adjust the pressure of the pressure relief by screwing off the release resistive bolt of one of the pressure release ports.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a pressure relief valve with adjustable pressure. Background technique [0002] The pressure relief valve can automatically open and close according to the working pressure of the system, and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the pressure relief valve, it will automatically open the pressure relief to ensure that the medium pressure in the equipment and pipeline is below the set pressure, protect the equipment and pipeline, and prevent accidents. The setting pressure of the current pressure relief valve is fixed and cannot be adjusted at will, so the scope of application is limited. Contents of the invention [0003] The purpose of the present invention is to propose a pressure relief valve with adjustable pressure, s...
