Abstract

The invention belongs to the technical field of valve machining, especially relates to a leakage-proof detection device for valve machining. For the problem of the detection accuracy, the following solution is presented: the device comprises a transparent detection box motors are arranged on the two sides of the outer wall of the bottom of the transparent detection box, output shafts of the motorsare connected with rotating rods through couplers, stirring rods distributed at equal intervals are arranged on the two sides of the outer wall of each rotating rod, the specifications and sizes of the stirring rods are different, the sizes of the stirring rods are gradually reduced from top to bottom, and an inverted horn-shaped structure is formed. According to the invention, the motors, the rotating rods, the stirring rods and the stirring blades are arranged; the sizes of the stirring rods are gradually reduced from top to bottom, the inverted horn-shaped structure is formed, the uneven stirring rods can form vortexes and water waves with different sizes, water flow impact with different sizes can be conducted on the valve, the situation that the valve is impacted by water flow can besimulated, and leakage-proof detection can be conducted on the valve more accurately.

Description

technical field [0001] The invention relates to the technical field of valve processing, in particular to a leak-proof detection device for valve processing. Background technique [0002] The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters of the conveying medium. 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 makes or stops the flow of media (liquid, gas, powder) in piping and equipment and controls its flow. [0003] In the production process of valves, the last process is to carry out leak-proof testing on valves, but there are still the following deficiencies in the current leak-proof testing of valves: the valve will be hit by a large water flow in actual use, but the current The detection device does not simulate a suitable water flow impact detection, and cannot accurately detect the leakage of the valve, which redu...
