Abstract
The invention relates to a reciprocating motion type air motor distributing valve which comprises a valve body, a valve rod and a seal ring. The reciprocating motion type air motor distributing valve further comprises a piece-type changeover valve block and a sealing cover. The valve body is provided with a changeover valve block cavity communicated with a valve rod cavity. The valve rod is provided with a clamping groove, wherein the width of the clamping groove is equal to the width of the piece-type changeover valve block which is of a rectangular structure. A cross section of the piece-type changeover valve block with the rectangular structure is the same with a cross section of the changeover valve block cavity. The piece-type changeover valve block is provided with a first rectangular face and a second rectangular face, wherein the first rectangular face is opposite to the second rectangular face. An air cavity is formed in a recessed mode in the second rectangular face which is opposite to the first rectangular face. The piece-type changeover valve block is arranged inside the changeover valve block cavity. The first rectangular face is clamped with the clamping groove in a matched mode. The sealing cover and an opening of the changeover valve block cavity are sealed with each other and are fixedly connected with each other. The sealing cover is provided with a guide hole and a screw thread hole, wherein the guide hole and the screw thread hole are communicated with the sealing cover. The reciprocating motion type air motor distributing valve has the advantage of being long in service life.
Description
Technical field
