Abstract

The invention discloses an air flow penetrating type regulating valve which comprises a valve sleeve and a partition plate. The partition plate is arranged in the valve sleeve, an inner cavity of the valve sleeve is divided into a main controlling cavity and a regulating cavity by the partition plate, an air inlet groove is formed in the middle of the outer wall of the valve sleeve, a left air groove and a right air groove which are symmetrical with each other are formed in the two sides of the air inlet groove, the left air groove and the right air groove are respectively communicated with air chambers of corresponding lateral edges, and a left air exhausting groove and a right air exhausting groove which are symmetrical with each other are respectively formed in the outmost side. Air holes communicated with the main control cavity are respectively formed in the bottoms of the air inlet grooves, the left air groove, the right air groove, the left air exhausting groove and the right air exhausting groove; a central venting hole communicated with the main control cavity and the regulating cavity is formed in the middle of the partition plate; and a third venting hole and a fourth venting hole which are symmetric with each other are respectively formed in the two sides of the central venting hole.

Description

Technical field [0001] The invention relates to an airflow penetrating control valve of a pneumatic diaphragm pump. Background technique [0002] Through searching, the applicant found a pneumatic diaphragm pump (patent number: 2012101329572) applied by the applicant Anhui Lechang Pneumatic Fluid Equipment Technology Co., Ltd., which discloses a product similar to the oxygenator of the present invention, which uses air source to generate The air pressure is used as power to drive the left and right reciprocating movement of the diaphragm; it sleeves the spool shaft (equivalent to the control shaft of the present invention) in the central spool. Both ends of the central spool are provided with step cavities, and the end spools The inner end surface is provided with a secondary annular step; the structure of the center valve core and the end valve core is complicated, which increases the production cost. Summary of the invention [0003] The technical problem to be solved by the pr...
