AI Technical Summary

Problems solved by technology

The upper and lower shells of pressure vessels with welded diaphragm accumulators are formed by welding process. Since the diaphragm made of rubber material is on the inner wall of the shell, electron beam or laser welding is required for welding, and the cost of welding equipment is relatively high.
The upper and lower shells of the pressure vessel with threaded diaphragm accumulators are screwed and fixed by threads. Since the outer part of the high-pressure resistant shell is connected by ring threads, it is heavyweight, large in size, and inconvenient to carry.

Abstract

The present invention relates to auxiliary device for hydraulic system, is one kind of wound diaphragm type accumulator, and aims at providing accumulator with low cost and high production efficiency. The wound diaphragm type accumulator includes locking socket head cap screw, pressure container, diaphragm and valve seat, and the pressure container includes an upper casing and a lower casing. The present invention features the integral upper casing and the integral lower casing of several layers of wound belt. The upper casing and the lower casing are integral, firm, low in cost and high in production efficiency. The accumulator has no-pollution forming process and is suitable for hydraulic system in automobile, metallurgical, medicine, food product and chemical industry.

Description

technical field [0001] The present invention relates to the field of auxiliary devices for hydraulic systems, specifically, it is installed in the hydraulic system and mainly plays the role of storing energy, stabilizing pressure, absorbing impact, eliminating pulsation, and damping vibration. Background technique [0002] At present, there are many types of accumulators, one of the auxiliary devices in the hydraulic system. In addition to its function of storing and releasing pressure, it is also used as a device for eliminating pressure pulsation. Compared with piston type accumulator and air bag type accumulator, diaphragm type accumulator has the characteristics of small size, light weight and fast action response. Therefore, it is widely used in the field of hydraulic system auxiliary devices. The upper and lower shells of pressure vessels with welded diaphragm accumulators are formed by welding process. Since the diaphragm made of rubber material is on the inner wall...
