A super high pressure relief system

Abstract

The invention discloses an ultrahigh pressure relief system. The ultrahigh pressure relief system comprises a double-acting piston type pressure relief cylinder and pressure relief pipelines. The double-acting piston type pressure relief cylinder comprises a cylinder barrel and a piston, wherein the cylinder barrel comprises a first pressure relief chamber, a second pressure relief chamber and a third pressure relief chamber. The second and third pressure relief chambers are correspondingly arranged on the left and right sides of the first pressure relief chamber, and communicate with the first pressure relief chamber. The diameter of the first pressure relief chamber is larger than the diameter of the second and third pressure relief chambers. The piston comprises a first piston and two second pistons, wherein the first piston is arranged in the first pressure relief chamber and the second pistons are correspondingly arranged in the second and third pressure relief chambers. The firstpiston and the second pistons are integrally arranged. The pressure relief pipelines comprise ultrahigh pressure pipelines and high pressure pipe lines. Compared with the prior art, the ultrahigh pressure relief system not only has controllable pressure relief quantitative value and adjustable rate, but also can realize continuous pressure relief for an ultrahigh pressure device. The ultrahigh pressure relief system has the advantages of having simple operation and high repeating control accuracy.

Description

technical field [0001] The invention relates to the field of fluid transmission and pressure control, in particular to an ultra-high pressure relief system. Background technique [0002] The ultra-high pressure relief system is an important part of each ultra-high pressure test device, and its function is to relieve the system pressure at a certain rate according to the parameters and indicators of the system. [0003] The ultra-high pressure relief system generally forms a complete pressure control system together with the ultra-high pressure booster system. At present, more and more enterprises have strict parameter index requirements for the pressurization rate and pressure release rate of the pressure control system, that is, the pressure release rate is required to be the same as the pressurization rate, and the value is controllable and the rate is adjustable to verify the equipment. Pressure resistance under alternating stress. Existing ultra-high pressure relief sy...
