Embodiment Construction

[0025] For a specific implementation of a plug valve durability test fixture of the present invention, please refer to Figure 1 to Figure 3 , the fixture includes a mounting base 3 , a rotating rod assembly 4 and a driving mechanism 5 for driving the rotating rod assembly 4 to reciprocate up and down along the mounting base 3 . The driving mechanism 5 includes a servo motor 51 , a screw mandrel 52 , a screw mandrel nut 53 , a slide rail 54 and a slide plate 55 . The servo motor 51 is fixedly installed on one side of the mounting base 3, and the other side of the mounting base 3 is fixedly equipped with a slide rail 54. The output shaft of the servo motor 51 is fixedly connected to the screw rod 52, and the screw nut 53 is sleeved on the screw rod 52. Above, the screw nut 53 is fixedly connected with the slide plate 55 , the slide plate 55 is connected with the slide rail 54 , and the rotating rod assembly 4 is fixedly installed on the slide plate 55 . The transmission mode i...

Abstract

The invention relates to the technical field of plug valves, and particularly relates to a plug valve durability test fixture. The plug valve durability test fixture comprises a mounting rod assembly,a mounting seat, a rotating rod assembly and a driving mechanism for driving the rotating rod assembly to reciprocate up and down along the mounting seat, wherein the rotating rod assembly comprisesa rotatable transmission rod body, the mounting rod assembly comprises a mounting rod body with a bearing, the bottom of the mounting rod body with the bearing is fixedly connected with a sleeve head,and the top of the mounting rod body with the bearing is arranged at the bottom of the transmission rod body in a sleeving mode through an elastic mechanism; and the elastic mechanism comprises an elastic piece for driving the mounting rod assembly to move upwards. Compared with the prior art, the elastic mechanism is arranged to counteract the self-weight of the mounting rod assembly, so that the pressure value of the driving mechanism acting on the rotating rod assembly is an actual pressure value, the durability test data of the plug valve is more accurate and effective, and the problem ofthe influence of the self-weight in the past is solved.

Description

technical field [0001] The invention relates to the technical field of plug valves, in particular to a plug valve durability test fixture. Background technique [0002] The plug valve for gas appliances is a closing member or a plunger-shaped rotary valve. It is generally equipped with a child lock mechanism. When in use, the knob needs to be pressed down. A valve that is opened or closed by aligning or staggering the passage openings on the plug and the passage openings on the valve body. [0003] In the production of plug valves, the on-off performance or service life of plug valves must be tested. Generally, the life of plug valves that meet market demand is about 50,000 times. The testing steps include pressing down, rotating 45 degrees to a small fire gear position, then rotate to the high fire position, and turn to the close position, there are many detection actions, which must use the automatic detection device. The existing plug valve durability test device has a c...
