Description

Technical Field

[0001] This utility model relates to the field of pipeline valve testing technology, and in particular to a valve testing device for pipeline valve processing. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. They are control components in pipeline fluid transport systems, used to change the cross-sectional area of ​​the passage and the direction of medium flow. The main function of valves is to control the fluid in the pipeline. In the case of large transport pipelines, it is necessary to ensure the quality of valves to avoid property damage. Therefore, in order to ensure the quality of valves, a sealing test is required after the valve is manufactured.

[0003] When testing valves, they need to be fixed in place first. Existing valve testing devices require valve calibration before fixing the valve using connectors. This fixing method is cumbersome and can only test valves of a single size, limiting its applicability. Utility Model Content

[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a valve testing device for pipeline valve processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a valve testing device for pipeline valve processing, including a base, an mounting seat fixedly installed at the upper middle part of the base, a gantry frame fixedly installed on the front and rear sides of the upper end of the base, a cylinder fixedly installed at the upper end of the gantry frame, a set of mounting seats identical to those at the upper end of the base fixedly installed at the telescopic end of the cylinder, a sealing gasket detachably installed at the middle of the surface of the mounting seat, an air tightness tester connected to the lower end of the mounting seat through an air inlet pipe, and a testing and determination mechanism connected to the upper end of the mounting seat through an air outlet pipe.

[0006] Furthermore, a threaded groove is provided in the middle of the surface of the mounting base, and a threaded portion is provided on the outer side of the lower end of the sealing gasket, the threaded portion being installed in conjunction with the threaded groove.

[0007] Furthermore, a vent is provided on the lower side of the interior of the mounting base. An air outlet pipe is connected to the vent of the upper end of the mounting base, and an air inlet pipe is connected to the vent of the lower end of the mounting base.

[0008] Furthermore, a connecting hole is provided in the middle of the sealing gasket, and the connecting hole is connected and communicates with the vent hole.

[0009] Furthermore, the detection and determination mechanism includes a water tank filled with clean water. An end cap is provided at the upper end of the water tank, and an air outlet pipe is fixedly installed on the upper end of the end cap. A detection and analysis camera is fixedly installed on the lower right side of the end cap. The detection and analysis camera is used to photograph whether air bubbles appear in the clean water and transmit the signal to the airtightness detector.

[0010] The beneficial effects of this utility model are as follows: Different specifications of sealing gaskets are replaced according to the diameter of the pipeline valve to be tested. Then, the pipeline valve to be tested is placed on the sealing gasket on the mounting base. Next, the cylinder is activated to press down the upper mounting base, causing the upper and lower sets of sealing gaskets to clamp and seal the pipeline valve. Then, the air tightness tester is activated to supply air into the pipeline valve. According to the detection and analysis camera, if air bubbles appear in the water tank, it indicates that the air tightness test is unqualified. Attached Figure Description
