Angle-adjustable valve positioning mechanism

Abstract

The invention provides an angle-adjustable valve positioning mechanism. The angle-adjustable valve positioning mechanism comprises a base, a supporting plate and a pressing mechanism, wherein the base is provided with two oblique supporting blocks; the supporting plate is obliquely mounted on the supporting blocks in a manner that the front part is lower than the back part; regulating plates corresponding to the supporting blocks are arranged at the bottom of the supporting plate; the front part of each regulating plate is rotationally connected with the front part of each supporting block by a rotating shaft; the rear part of each regulating plate is provided with a locking hole; the rear part of each supporting block is provided with a plurality of height regulating holes; the regulating plates and the supporting blocks are fixed by positioning pin shafts which penetrate into the height regulating holes and the locking holes. During use of the angle-adjustable valve positioning mechanism disclosed by the invention, an oblique flange surface of an oblique valve body is supported on the supporting plate and is primarily positioned by a bolt and a positioning hole; the side surface of the valve body is shielded by a positioning block, and then the valve body is pressed by a pressing mechanism; the supporting plate can rotate about the rotating shaft by virtue of the regulating plates to regulate the angle so as to adapt to clamping of valve bodies at different inclination angles.

Description

technical field [0001] The invention belongs to the technical field of fixtures, in particular to an angle-adjustable valve positioning mechanism. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that allows the medium (liquid, gas, powder) in the piping and equipment to flow or stop and can control its flow. The processing accuracy of the valve directly affects the sealing performance of the entire pipeline. [0003] At present, most valves have horizontal flange surfaces at both ends, which are convenient for processing and positioning; with the demand of the market, there have been valve bodies with one end flange as a horizontal surface and the other end flange as an inclined surface, which cannot be achieved by using conventional tooling. Clamping and positioning are not convenient for processing horizontal flange surfaces, and traditional tooling cannot adapt to valve bodie...

[0003] At present, most valves have horizontal flange surfaces at both ends, which are convenient for processing and positioning; with the demand of the market, there have been valve bodies with one end flange as a horizontal surface and the other end flange as an inclined surface, which cannot be achieved by using conventional tooling. Clamping and positioning, it is not convenient to process the horizontal flange surface, and the traditional tooling cannot adapt to the valve body with different inclination angles, each type of valve body must make a separate tooling, which increases the cost
