Description

Technical Field

[0001] The utility model relates to the technical field of blind plates, in particular to a quick-cut blind plate device. Background Art

[0002] In industries such as petroleum, chemical engineering, and offshore platforms, blind plates serve as a reliable isolation method, completely separating media and preventing production disruptions or even accidents caused by loose shut-off valves. Switching between blind plates is a complex, time-consuming, and labor-intensive process. Each switch requires loosening bolts, prying open the pipe, inserting and removing the blind plate, installing a spiral wound gasket, and tightening the bolts. Longer blind plate switching times result in increased downtime, resulting in lost production time and reduced profitability. When the medium in the pipeline is toxic, workers are at risk of poisoning, necessitating the fastest possible completion of the work.

[0003] Since the traditional technical solutions are faced with the above-mentioned deficiencies, it is urgent to develop a quick-cut blind plate device to solve the above-mentioned problems. Utility Model Content

[0004] The object of the utility model is to provide a quick-cut blind plate device, comprising a left valve body and a right valve body, wherein a blind plate is provided in the gap between the left valve body and the right valve body, a sealing seat is provided above the side of the left valve body close to the blind plate, a traction plate is provided above the sealing seat, the traction plate is connected to the guide wheel through a fastening bolt, a sealing ring is provided below the sealing seat where it contacts the guide wheel, a sealing ring pressure plate is provided on one side of the sealing ring, a cam one is provided on the side of the guide wheel away from the traction plate, the cam one is rotatably connected to the cam two, a guide plate is provided on the outer surface of the cam two, a sliding nut is provided at the corresponding position below the guide plate, the sliding nut is sleeved on the rotating valve stem, one side of the rotating valve stem passes through a locking plate provided on one side of the left valve body, and is connected to a handwheel, a locking disk is also provided on the rotating valve stem, and the locking disk cooperates with the locking plate.

[0005] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention sets a handwheel, a rotating valve stem, a sliding nut, a guide plate, cam one, and cam two. By rotating the handwheel, the handwheel rotation drives the rotating valve stem to rotate, and the rotating valve stem rotation drives the sliding nut to move, and then the guide plate drives the cam two to rotate, and the rotation of the cam two drives the cam one to rotate. At the same time, it can also perform axial linear motion, so that the sealing seat is close to or away from the flange of the left valve body, thereby achieving the purpose of quickly switching the open position or the closed position. The operation is simple, the time from open to closed or from closed to open of the blind plate device is short, and it is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
