Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a valve with a locking device. Background Art

[0002] A valve is a mechanical device that controls the flow, direction, pressure, temperature, etc. of a flowing fluid medium. A valve is a basic component in a piping system. Valve fittings are technically the same as pumps and are often discussed as a separate category. Valves can be operated manually or with a handwheel, handle, or pedal, and can also be controlled to change the pressure, temperature, and flow of the fluid medium. Valves can operate these changes continuously or repeatedly.

[0003] According to a valve with a locking device disclosed (publication number: CN 2610192Y): it includes a valve body and a valve stem, and the valve stem is composed of an upper valve stem and a lower valve stem. An electromagnetic clutch device is provided between the upper valve stem and the lower valve stem, and the electromagnetic clutch device is composed of a power supply, an electronic switch, a floating iron core, and an electromagnetic coil. The electromagnetic coil is arranged on the outside of the floating iron core. In the above application, the electromagnetic clutch device is composed of a power supply, an electronic switch, a floating iron core, and an electromagnetic coil. When the locking device is working, the valve cannot be fixedly connected, which needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a valve with a locking device, which can effectively fix the valve during operation through the fixing device. When the hand wheel is turned, the hand wheel drives the connecting block to rotate, and the rotation of the connecting block drives the baffle to rotate. At this time, the baffle leaves the front end of the rock grabber, so the rock grabber is not blocked by the baffle, and the second spring extends outward to enter the wall to achieve the fixing effect, thereby solving the existing problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a valve with a locking device, comprising a valve body, a water inlet is provided on one side of the valve body, a water outlet is provided on the other side of the valve body, and a connecting port is provided on the top of the valve body;

[0007] A locking device is provided inside the valve body, and the locking device includes a ball valve, the circumferential surface of the ball valve is rotatably connected to the inner wall of the valve body, the ball valve is provided with a connecting groove, a valve stem is fixedly connected inside the connecting groove, the circumferential surface of the valve stem is rotatably connected to the inside of the connecting port, a fixing block is fixedly connected to the top of the valve stem, a handwheel is fixedly connected to the side of the fixing block, a fixing groove is provided on the circumferential surface of the valve stem, a fixing pin is slidably connected to the inner wall of the fixing groove, and a pin hole is provided on the side of the connecting port.

The function of the elastic connection of one end of the fixing pin to the inner wall of the valve stem via the first spring is to cause the valve stem to rotate when the hand wheel is rotated, so that the fixing pin enters the pin hole through the first spring to achieve a locking effect.

[0009] Furthermore, a threaded rod is fixedly connected to the top of the valve stem, a gasket is threadedly connected to the circumferential surface of the threaded rod, a nut is threadedly fixed to the circumferential surface of the threaded rod, and a sealing ring is rotatably connected to the circumferential surface of the ball valve. The function of the gasket and the nut is to fix the handwheel when it is connected to the fixed block to prevent the handwheel from falling off in the event of a worker's misoperation, thereby achieving a safety effect.

[0010] Furthermore, the shape of the fixing block is set to be diamond-shaped, the gasket is located below the nut, the number of the pin holes is set to eight, and is arranged in a circular array along the vertical axis of the connecting port, the gasket is located below the nut to prevent wear between the nut and the handwheel, which is beneficial to extending the service life of the nut, and the number of the pin holes is set to eight to achieve multi-directional locking and change the flow rate of the ball valve at different angles.

[0011] Furthermore, a fixing device is provided on the top of the valve body, and the fixing device includes a connecting block, the side of the connecting block is fixedly connected to the circumferential surface of the handwheel, the bottom of the connecting block is fixedly connected to a baffle, the top of the valve body is fixedly connected to a support plate, the side of the support plate is fixedly connected to a second spring, one end of the second spring is fixedly connected to a rock grabber, the rock grabber is elastically connected to the side of the support plate through the second spring, the bottom of the connecting block is fixedly connected with the baffle for limiting the rock grabber from extending forward, the rock grabber is elastically connected to the side of the support plate through the second spring for the baffle to leave when the handwheel is rotated, and the rock grabber pops up forward through the elasticity of the second spring and enters the wall, thereby achieving a fixing effect.

[0012] Furthermore, the side of the support plate is fixedly connected to a limiting plate, and the role of the side of the support plate being fixedly connected to the limiting plate is to prevent the rock grabber from popping out to the side when it pops out forward through the elasticity of the second spring, thereby achieving the effect of limiting the displacement direction of the rock grabber.

[0013] Furthermore, the number of the limit plates is set to two groups, and they are symmetrical to each other along the vertical center axis of the support plate. The purpose of setting the number of the limit plates to two groups is to limit the two sides of the rock grabber at the same time.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model realizes flow control of the ball valve through the cooperation between the hand wheel of the locking device, the valve body, the ball valve and other components. At the same time, the rotation of the valve stem drives the fixed pin inside the fixed groove to rotate. When the fixed pin rotates and passes through the latch hole, the fixed pin extends into the latch hole through the first spring to lock the valve stem. The sealing ring between the valve stem and the ball valve is to prevent leakage when the valve is working. Because eight latch holes are provided on the circumferential surface of the connecting port, the fixed pin can achieve both quantitative water output and multiple locking effects.

[0016] 2. The fixing device of the utility model, when the valve is installed, in order to prevent the valve from shaking due to instability during operation, the fixing device is used to effectively fix the valve during operation. When the hand wheel is turned, the hand wheel drives the connecting block to rotate, and the rotation of the connecting block drives the baffle to rotate. At this time, the baffle leaves the front end of the rock grabber, so the rock grabber is not blocked by the baffle and extends outward through the second spring to enter the wall to achieve the fixing effect.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
