Embodiment Construction

[0007] Attached below figure 1 Describe the specific implementation;

[0008] attached figure 1 The middle cylinder 11 promotes the piston 12 to move to the left, and the spool 14 blocks the upper and lower through holes of the spool cover 2 to close the sand valve. Cylinder 12 pulls piston 12 to move to the right, and the upper and lower through holes of valve core cover 2 are exposed, and sand valve is opened. The handle 4 rotates the valve core sleeve 2 radially through the adjusting claw 6, and radially adjusts the opening and closing size of the upper and lower through holes and the inner hole of the valve body to adjust the sand amount. figure 2 It is the situation when the sand valve partially closes the valve core sleeve and the inner hole of the valve does not overlap, and the amount of sand decreases. attached image 3 It is the view of the coincidence of the valve core sleeve and the inner hole of the valve, and the situation when the amount of sand is the larg...

Abstract

Most of the existing sandblasting valves only plays a role of switching and the sandblasting valves which can regulate the sand quantity have short operation life, which is a problem troubling the sandblasting operation for a long term. The invention divides the working cylinder and the plug of the sand valve into two independent parts, thus not only utilizing the existing finished cylinders but also avoiding that sand channeling from the plug to the cylinder causes early damage. In particular, the invention ingeniously utilizes the body and the plug housing of the sand valve and regulates the sand quantity through radial rotation of the valve plug housing, and being sprayed with hard alloys, the valve body, the valve plug and the valve plug housing are convenient and practical and greatly prolong the operation life of the sand valve.

Description

technical field [0001] A radially adjustable long-life sandblasting valve belongs to the technical field of surface spraying. Background technique [0002] Most of the existing sandblasting valves can only function as switches, and the sandblasting valves that can adjust the amount of sand have a short working life, which is a long-term problem in sandblasting operations. Contents of the invention [0003] The invention divides the working cylinder of the sand valve and the valve core of the sand valve into two independent parts, which can not only utilize the existing finished cylinder, but also avoid the early damage caused by the valve core moving sand to the cylinder. Especially in the present invention, the sand valve body and the valve core sleeve are skillfully utilized, and the radial rotation of the valve core sleeve is used to adjust the amount of sand. It is practical and greatly prolongs the working life of the sand valve. Description of drawings [0004] a...
