An automatic continuous pressure test device for a water distributor

Abstract

The present invention relates to a water distributor automatic and continuous pressure test device. The device comprises a mounting rack and a control system, the mounting rack is provided with a pressure test barrel, a hydraulic cylinder distributed with the pressure test barrel in a coaxial line mode and configured to push a water distributer into the pressure test barrel and an electromagnet locating the pose of the water distributer, two ends, perpendicular to the axis direction of the pressure test barrel, of the electromagnet is are respectively provided with slant rails, the lower sideof the mounting rack is provided with a plate turnover device configured to push the water distributer out of the slant rails, a barrel port, far away from the mounting rack, of the pressure test barrel is connected with a seal head, the pressure test barrel is provided with an outer pressure test port, an upper seal head is provided with an inner pressure test port, the mounting rack is providedwith an electric torquemeter connected with a measurement and regulation drive rod, and the output end of the hydraulic cylinder is connected with a valving fishing grip and a lower seal seat. The water distributor automatic and continuous pressure test device can automatically dismount the pressure test joint to reduce the damaging and quality risk for the water distributer and reduce the safetyrisk of workers, is high in automatic degree of the whole device, facilitates reduction of worker workload and time and improves working efficiency.

Description

technical field [0001] The invention relates to the technical field of water distributor testing machinery, in particular to an automatic continuous pressure test device for a water distributor. Background technique [0002] At present, the current status of the pressure test inspection of the concentric water distributor by the enterprise is as follows: 1. Manually install and disassemble the upper and lower pressure test joints, and conduct the internal pressure static sealing test; 2. Manually detect the torque of the water distributor under pressure (25MPa); 3. , Manually put the water distributor into the pressure test cylinder, and carry out the external pressure static sealing test. To carry out the above three operations, it is necessary for the test personnel to repeatedly enter and exit the pressure test room. [0003] However, the potential safety and quality risks of disassembling and assembling the pressure test tooling are as follows: [0004] 1. Due to the n...

Problems solved by technology

[0003] However, the potential safety and quality risks of disassembling and assembling the pressure test tooling are as follows:

[0004] 1. Due to the need to repeatedly disassemble and assemble the pressure test joint, due to different assembly personnel or the use of different assembly tools, the tightening torque generated when assembling the pressure test joint is different, and the taper thread of the upper and lower joints of the water distributor will be squeezed and damaged Each is different, there is a quality risk

[0005] 2. Due to the need to detect the switching torque of the water distributor under the working condition of 25MPa internal pressure, the tester needs to use the torque meter to test the torque under the working condition with pressure, which has a safety risk

[0006] 3. At present, the average time to complete the inspection of a single water distributor is about 50 minutes. During this period, the operator needs to enter the pressure test workshop for 4 disassembly and test work. When inspecting water distributors in batches, there is a large workload and a lot of labor time. High, but the work efficiency can not reflect the problem
