Description

Technical Field

[0001] The invention relates to the technical field of valves, in particular to a special leak-proof sealing component for valves. 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. The valve 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. The valve can operate these changes continuously or repeatedly, such as the safety valve installed in a hot water system or steam boiler. In more complex control systems, automatic control valves are used according to the needs of external inputs (i.e., adjusting the constantly changing set points of the flow through the pipeline). Automatic control valves do not require manual operation, and according to their inputs and settings, the valve accurately controls the various requirements of the fluid medium.

[0003] However, the sealing effect of the valve opening in the prior art is not ideal, which makes the valve complicated to install, and the sealing between the sealing rings is not tight enough, resulting in dripping due to loose sealing during use. Summary of the invention

[0007] A connector is provided on the right side of the connecting port, a sealing layer is fixedly connected to the rear end of the connector, a second screw hole is fixedly connected in an array on the upper surface of the sealing layer, and a flow port is fixedly connected to the front end of the connector, a sealing body is provided on the right side of the connector, a sealing ring is fixedly connected to the front end of the sealing body, a screw hole one is fixedly connected in an array on the upper surface of the sealing ring, the sealing ring is symmetrically fixedly connected to a fixing block, a locking groove is fixedly connected to the front end of the fixing block, and a plug is fixedly connected to the rear end of the sealing body.

[0008] As a further solution of the present invention: a hollow groove is fixedly connected to the inner wall of the connector, and an inner cavity is provided inside the connector to facilitate the outflow of liquid in the valve to prevent blockage during use.

[0009] As a further solution of the present invention: the top end of the engaging seat is fixedly connected to a base, and the upper end of the base is fixedly connected to a rotating member, which is convenient for clamping and loosening of the wrench.

[0010] As a further solution of the present invention: a wrench is fixedly connected to the left side of the rotating member, and a snap rod is fixedly connected to the right side of the rotating member, so that the snap rod can be used to lock the sealing body.

[0011] As a further solution of the present invention: a connecting port is fixedly connected to the right side of the valve tube, and a thread is fixedly provided in the connecting port, so that the screw rod can be used to fix other objects conveniently and quickly.

[0012] As a further solution of the present invention: a screw is meshedly connected within the thread, and a rotating nut is fixedly connected to one end of the screw far from the thread, so as to facilitate the adjustment of the sealing tightness of the device.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention blocks the flow hole in the connecting body by a plugging head, and cooperates with the screw rod, the rotating nut and the screw hole on the sealing body to make the valve tube tightly sealed when not in use without leakage. The tight connection has a good technical effect, and the cost is low and easy to implement, so it has a good promotion prospect.

[0015] 2. The present invention uses the interaction between the rotating part arranged at the top of the locking seat and the wrench and the movable rod to make the movable rod locking groove further reinforce the structure at the sealing port, thereby improving the sealing effect. At the same time, the device is easy to install and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
