Embodiment 1

[0026] Embodiment 1: see Figure 1 to Figure 6 , a testing device for ball valve airtightness and torque detection, comprising a square bench 1, a fixed sealing cover 4 is provided on the right side of the bench 1, and a movable sealing cover 3 is provided on the left side The movable sealing cover 3 is arranged opposite to the fixed sealing cover 4, and the movable sealing cover 3 can translate to the fixed sealing cover 4 for clamping the two ends of the sealing ball valve 21. The rear side of the movable sealing cover 3 is provided with a movable sealing cover 3 The translation driving mechanism 2, the translation driving mechanism 2 is an air cylinder or a hydraulic cylinder; the fixed sealing cover 4 and the movable sealing cover 3 are provided with test air holes 24 for the airtightness test of the ball valve 21.

[0027] The inside of the bench 1 is also provided with a torque testing mechanism 5, the torque testing mechanism 5 is located between the fixed sealing cover...

Embodiment 2

[0032] Example 2: see Figure 1 to Figure 4 ,as well as Figure 7 , Figure 8 , The difference between this embodiment and Embodiment 1 is that the structures of the fixed sealing cover 4 and the movable sealing cover 3 are changed, and the other contents are the same. The fixed sealing cover 4 and the movable sealing cover 3 described in this embodiment are planes, and the opposite inner surfaces of the two sealing covers are provided with annular wedge flanges 38, and the inner sides of the wedge flanges 38 are provided with silicone rubber. Seal ring 39. When the two sealing covers move toward the ball valve 21 and clamp and seal, the wedging flange 38 contacts the end face of the ball valve 21, and a certain sealing effect is achieved through extrusion and embedding, and then the sealing ring 39 on the inner side of the wedging flange 38 contacts with the end face of the ball valve 21. The end surface of the ball valve 21 is extruded to realize secondary sealing.

Abstract

The invention discloses a test device for ball valve airtightness and torque detection, which comprises a frame, a fixed sealing cover is provided on one side of the frame, and an opposite side of the fixed sealing cover is provided inside the frame. The side is provided with a movable sealing cover that can translate to the fixed sealing cover, and the rear side of the movable sealing cover is provided with a translation drive mechanism; at least one of the fixed sealing cover and the movable sealing cover is provided with a test air hole; There is also a torque testing mechanism inside the frame, the torque testing mechanism is located between the fixed sealing cover and the movable sealing cover, and the torque testing mechanism includes a slide table that can slide between the two sealing covers. In order to solve the problems of low air tightness test efficiency, inconvenient clamping, and inability to perform both air tightness test and torque test at the same time, the present invention proposes a test method with high test efficiency, convenient clamping, and simultaneous air tightness test and torque test. Ball valve test equipment for torque testing.

Description

technical field [0001] The invention relates to the field of ball valve testing machines, in particular to a testing device for ball valve air tightness and torque detection. Background technique [0002] Ball valves are commonly used opening and closing parts for gas or liquid circulation. They are generally used in two important industries: gas pipeline network and water conservancy transportation. Therefore, leak detection and torque testing are required before leaving the factory, otherwise there will be greater safety hazards. [0003] In the prior art, the test methods for ball valves are relatively traditional. When performing air tightness tests, gaskets or seal rings are usually placed outside the two ends of the ball valve, and at the same time, force-applying devices such as jacks or hydraulic cylinders are used to clamp both ends of the ball valve, thereby Make the gasket or sealing ring form a seal with the two ends of the ball valve, immerse the entire sealed b...
