Problems solved by technology

The traditional ultra-high pressure seawater pressure balance valve adopts a slide valve structure, which completely relies on the cooperation between the valve core and the metal surface of the valve seat to achieve sealing. The seawater in the environment is sealed, and the scope of application is limited

Embodiment Construction

[0012] As shown in the drawings, the ultra-high pressure seawater pressure balance valve of the present invention includes a valve seat 1 , a valve body 8 and a valve sleeve 7 . The valve body 8 is a T-shaped tee. Both the valve seat 1 and the valve sleeve 7 are tubular, and the outer diameter of a section of their inner end is smaller than that of the outer section, thereby forming a step in the middle of their outer circle, and they respectively extend into the two ends on the same axis of the valve body 8; Grooves are processed on their steps and on the outer circle inside the steps, and rubber sealing rings 21 and 22 are respectively embedded in the grooves. Through the sealing rings, the gap between the valve seat 1 and the valve body 8 and between the valve body 8 and the valve sleeve are realized. 7 between the seals. The inner end of the valve seat 1 and the end connected to the valve body 8 are respectively processed with external and internal threads, and the two ar...

Abstract

The invention discloses an ultra-high sea-water pressure balance valve, comprising a valve seat, a valve body and a valve pocket. The valve body is a tee joint. Both the valve seat and the valve pocket are in a tubular shape, the inner ends of the valve seat and the valve pocket are sealed, inserted into and fixed on the two ends sharing the same axial line with the valve body, and a segment inner hole of the inner end of the valve body is a taper hole. A valve flap and a spring are arranged inside the valve body. One end of the valve flap is arranged in the valve body, and the other end is inserted into the valve pocket. A taper head is arranged at one end of the valve flap, and the taper angle of the taper head is equal to the taper angle of the taper hole of the inner end of the valve seat; under non-working state, the taper head of the valve flap is arranged against the taper hole of the inner end of the valve seat. A spring is coated on the valve flap. Under non-working state, the taper head of the valve flap and the taper hole of the inner end of the valve seat closely match with each other by the seal ring. The invention can not only seal the hydraulic oil with relatively big viscosity, but also seal deep-ocean water, and the scope of application is not limited. The invention can be used to adjust the balance of the weight and buoyancy of a deep-ocean robot.

Description

technical field [0001] The present invention relates to a valve. Specifically, it is an ultra-high pressure seawater pressure balance valve used to adjust the weight and buoyancy balance of deep-sea robots. Background technique [0002] It is well known in the shipbuilding industry that when a deep-sea underwater robot is operating underwater, it needs to accurately adjust its weight and buoyancy balance according to each operation task and the number of loads. Therefore, the underwater robot is equipped with a buoyancy fine-tuning mechanism with a seawater pump and a pressure-resistant water tank, and the ultra-high pressure seawater pressure balance valve is an important part of the buoyancy fine-tuning mechanism. The traditional ultra-high pressure seawater pressure balance valve adopts a slide valve structure, which completely relies on the cooperation between the valve core and the metal surface of the valve seat to achieve sealing. The seawater in the environment is ...
