Novel control valve

Abstract

The invention relates to the field of valve bodies, and discloses a novel control valve. The control valve comprises a mounting seat, a first chamber, a second chamber and air storage equipment; the first chamber and the second chamber are mounted on the left and right sides of the top of the mounting seat respectively; the right side wall of the first chamber is fixedly connected with the left side wall of the second chamber; the right side wall of the air storage equipment is fixedly connected with an air inlet pipe; the right end of the air inlet pipe is fixedly connected with the left endof the first chamber; a separating plate is fixedly connected inside the first chamber; a stepped hole is formed in the middle of the separating plate; a stepped plug matched with the stepped hole isinserted in the stepped hole; and a fixing plate is fixedly connected with the right end of the stepped plug. According to the novel control valve, periodic air pumping and air exhausting of the wholeequipment can be realized through high-speed extension and retraction of an electric pushing rod, the ventilation efficiency can be guaranteed while the ventilation effect is guaranteed, the whole equipment is applicable to high-energy ventilation work, and the accuracy of the control valve during ventilation can also be guaranteed.

Description

technical field [0001] The invention relates to the field of valve bodies, in particular to a novel control valve. Background technique [0002] The impact test is generally a test method to determine the safety, reliability and effectiveness of the military and civilian equipment when they are subjected to external force impact or action. The impact test bench is mainly used for the mechanical environment test of the product, which can simulate the actual impact pulse and impact energy, to simulate the non-repetitive impact that the product is expected to suffer during use, loading and unloading, and transportation, so as to determine the adaptability of the product to various impact environments. [0003] Among the current shock test specifications, one is to specify the shock motion (such as half-sine pulse, rear-peak sawtooth pulse, etc.) and its tolerance requirements. The other is the shock response spectrum specification, which describes the damage caused by shock mo...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a new type of control valve, which solves the problem that the current control valve used in the impact test has a relatively slow ventilation efficiency, and it is difficult to realize precise control of the valve body and large energy exchange. Gas, unable to meet the needs of the impact test
