Problems solved by technology

However, in recent years, the development of ultra-high pressure and high-flow pressure reducing valves has gradually emerged. Some ultra-high pressure pressure reducing valves have an inlet pressure as high as 60MPa. The flow rate of the pressure valve is large enough and has high reliability. The above requirements bring difficulties to the development of the pressure relief valve. The development of the ultra-high pressure pressure relief valve is one of the key technologies for the development of the extrusion servo system.

Abstract

The invention relates to a superhigh-pressure pressure-reducing valve performance testing bench. The structure is as follows: in a casing, a filter is connected with the inflation port of a gas cylinder through a pipeline; the inflation port of the gas cylinder is connected with the air inlet of a pressure-reducing valve through the pipeline; the air outlet of the pressure-reducing valve is connected with a gas flowmeter; and the gas flowmeter is connected with a damping orifice plate through a pneumatic valve. The superhigh-pressure pressure-reducing valve performance testing bench solves the problems of designing, manufacturing and installing of a testing bench in a large-flow pressure-reducing valve performance testing system with gas medium pressure reaching superhigh pressure of 60 MPa and a pressure-reducing valve maximum flow being 120 L / min.

Description

technical field [0001] The invention relates to a device for testing the performance of a pressure reducing valve, in particular to a performance test bench for an ultrahigh pressure pressure reducing valve, which belongs to the field of pneumatics. Background technique [0002] At present, the pressure reducing valve comprehensive performance test bench in the market generally has a rated pressure of 0-32MPa, and can only test the performance of high pressure reducing valves with medium and low pressure and inlet pressure ≤ 32MPa. However, in recent years, the development of ultra-high pressure and high-flow pressure reducing valves has gradually emerged. Some ultra-high pressure pressure reducing valves have an inlet pressure as high as 60MPa. The flow rate of the pressure relief valve is large enough and has high reliability. The above requirements bring difficulties to the development of the pressure relief valve. The development of the ultra-high pressure pressure relie...
