Combined throttling valve debugging tool

Abstract

The invention discloses a combined throttling valve debugging tool. The combined throttling valve debugging tool comprises throttling valve cores, shut-off plugs, a throttling seat, a shunting cover and a fastener, wherein the throttling seat comprises a connecting part and a shut-off plug mounting part, a plurality of first assembling holes are formed in the connecting part in the direction parallel to the axis of the connecting part, and the first assembling holes are provided with the throttling valve cores; a plurality of second assembling holes are formed in the shut-off plug mounting part in the radial direction, and the shut-off plugs are arranged in the second assembling holes; a plurality of throttling flow channels and a converging flow channel are formed in the shut-off plug mounting part, one ends of the throttling flow channels communicate with the second assembling holes in a one-to-one correspondence mode and the other ends of the throttling flow channels converge on the converging flow channel, and the converging flow channel penetrates through the shut-off plug mounting part in the direction away from the connecting part; the throttling valve cores communicate with the throttling flow channels in a one-to-one correspondence mode; the shunting cover is fixedly connected with the connecting part, a plurality of shunting channels penetrating through the shunting cover are formed in the shunting cover, one ends of the shunting channels communicate with the throttling valve cores in a one-to-one correspondence mode, and the other ends of the shunting channels converge integrally; and the fastener is used for fastening the shunting cover to the throttling seat.

Description

technical field [0001] The invention relates to a throttle valve debugging tool, in particular to a combined throttle valve debugging tool used in the debugging test of an air-conditioning and refrigeration system. Background technique [0002] For the air-conditioning and refrigeration system with the throttle valve as the throttling component, in the process of research and development, it is necessary to determine the required matching throttle valve through multiple debugging tests, which means that the entire debugging test process needs to replace the throttle valve many times. valve, and replacing the throttle valve is a very cumbersome job. It is necessary to evacuate the refrigerant first, then remove the unused throttle valve, then install another throttle valve with a different spool, and then vacuumize. Filling refrigerant is time-consuming and labor-intensive. [0003] In order to improve this situation, the single tooling of the throttle valve has been put int...
