Abstract

The invention discloses a multi-connected integrated assembling valve seat. The multi-connected integrated assembling valve seat comprises a valve seat body, wherein multiple air grooves I, multiple air grooves II, multiple valve nozzle installation holes I and multiple valve nozzle installation holes II are formed in the valve seat body; valve nozzles I and valve nozzles II are arranged in the valve nozzle installation holes I and the valve nozzle installation holes II; one side of each valve nozzle installation hole I is provided with an air inlet passage I which is connected with the corresponding air groove I; the air inlet passages I are connected with input openings I; the valve seat body is provided with an air inlet passage II and an air inlet passage III; the air inlet passage II is connected with an air passage I; an air output opening I of the air passage I is formed in the front end surface of the valve seat body; an air output opening II is formed in the valve seat body; the valve nozzle installation holes I are connected with the air passage I; the air inlet passage III is connected with an input opening II; the air inlet passage III is connected with the air grooves II. According to the multi-connected integrated assembling valve seat disclosed by the invention, by changing a pilot valve seat which is in dispersed installation into an integrated installation structure, the assembling number and the installation space of parts are reduced, the difficulty of a machining technology is reduced, the problems of an existing pilot valve seat that the occupied space is large and the whole weight is heavy are solved, and the multi-connected integrated assembling valve seat is particularly suitable for scale production.

Description

technical field

[0001] The invention relates to the technical field of pneumatic equipment, in particular to a multi-connected manifold valve seat. Background technique

[0002] Pneumatic equipment in the prior art widely uses the pilot valve structure. There are many problems in the prior art pilot valve structure. For example, multiple pilot valves need to be used in the same equipment or system at the same time. Pilot valve seat, so multiple pilot valve seats occupy a large installation space, the structure is heavy, and not compact. At the same time, due to the large number of parts to be processed, the sealing and matching surfaces between parts are processed with high precision, the process is complicated, and the quality is not easy. control, the processing quality is prone to fluctuations, and the production efficiency is low. Contents of the invention

[0003] The purpose of the present invention is to provide a multi-connected manifold valve seat to solve the ab...
