Embodiment Construction

[0009] As shown in the drawings, the ultra-high pressure seawater safety valve of the present invention includes a valve body 1, which is tubular, with a water inlet 8 at one end and a gland 5 fixed at the other end. The end of the gland 5 connected to the valve body 1 is respectively processed with an internal thread and an external thread, and the gland 5 is fixed with the valve body by means of the internal thread and the external thread.

[0010] The center of the cover bottom of the gland 5 is processed with a screw hole, and the screw hole is equipped with a pressure regulating screw 7. Between the water inlet 8 and the gland 5, a valve flap 3, a spring 4 and a spring seat 6 are sequentially arranged. The inner diameter of the water inlet 8 is smaller than the diameter of the inner cavity of the valve body 1, and the connection between the water inlet 8 and the inner cavity of the valve body 1 is processed into a conical surface, and a steel ball 2 is arranged between th...

Abstract

The invention discloses an ultra-high seawater pressure relief valve, comprising a valve body. The valve body is in a tubular shape, a water inlet is arranged at one end of the valve body, and a gland is arranged at the other end; a screw hole is arranged at the center of the bottom of the gland, and a regulating screw is arranged in the screw hole. A valve flap, a spring and a spring seat are successively arranged between the water inlet and the gland. The inner diameter of the water inlet is smaller than the intracavity diameter of the valve body, and the joint between the water inlet and the intracavity of the valve body is a taper plane; a steel ball is arranged between the taper plane and the valve flap; under non-working state, the steel ball is propped tightly against the taper plane by the regulating screw, the spring seat, the spring and the valve flap. The ultra-high seawater pressure relief valve can not only seal the hydraulic oil medium with relatively big viscosity, but also seal seawater medium with relatively low viscosity, and the scope of application is not limited. The invention is applicable to relieve the pressure of ultra high pressure seawater pumps under deep-ocean environment.

Description

technical field [0001] The invention relates to a safety valve. Specifically, it is an ultra-high pressure seawater safety valve that can relieve the pressure of an ultra-high pressure seawater pump in a deep sea environment. Background technique [0002] At present, the ultra-high-pressure seawater safety valves used to relieve the pressure of ultra-high-pressure seawater pumps in deep-sea environments are all hydraulic direct-acting safety valves. This hydraulic direct-acting safety valve adopts a slide valve structure, which can only seal the hydraulic oil medium with high viscosity, but cannot seal the seawater medium with low viscosity, so the scope of application is limited. Contents of the invention [0003] The problem to be solved by the present invention is to overcome the defects of the background technology and provide an ultra-high pressure seawater safety valve. This ultra-high pressure seawater safety valve can not only seal the hydraulic oil medium with h...
