Description

An expansion-sealed ceramic spool universal angle valve

technical field

The utility model belongs to the technical field of angle valves, in particular to an expansion-sealed ceramic valve core universal angle valve.

Background technique

Angle valve is an important product in plumbing equipment. In the tap water pipeline, the angle valve is usually arranged between the water pipe and the faucet, and is used to open or close the water source inflow of the faucet. At the same time, when the water tap is damaged, the angle valve can be closed to facilitate the repair or replacement of the water tap. When the existing angle valve is installed on the water pipe, it is often necessary to tie a waterproof tape on the water inlet end of the angle valve to prevent water leakage at the connection, or to have high requirements for the sealing of the connection of the angle valve. It can provide a good sealing angle valve. When the angle valve is connected to the water pipe, the water inlet of the angle valve is fixed, and the outlet of the same angle valve is also fixed, which makes the use of the angle valve very rigid. Reinstallation is required to get the spout in the correct position.

Contents of the invention

Aiming at the above problems, the utility model provides a universal angle valve with simple structure and good sealing performance.

The purpose of this utility model is achieved in that:

An expansion-sealed ceramic spool universal angle valve, comprising a spool, a valve stem, a hand wheel, and a valve body with a water inlet and a water outlet. Hole 1, one end of the valve rod extends into the valve body and connects with the valve core, and the other end extends out of the valve body to connect with the hand wheel; the valve body at one end of the water inlet extends outward to form a sealing part, which is sealed The edge of the part is formed with a limiting protrusion, and the outer periphery of the sealing part is covered with a plastic king ring, and the plastic king ring is limited on the sealing part by the limiting protrusion.

One side of the lower tile is bonded with an upper tile that controls the opening or closing of the liquid inlet, the upper tile is connected to the valve stem, and the other side of the lower tile is connected with a silicone pad and a card in turn. Pad, the card pad is embedded inside the valve body, and limits the axial movement of the silicone pad, the lower ceramic piece and the upper ceramic piece. .

In the above expansion-sealed ceramic valve core universal angle valve, the valve body includes a water inlet valve body and a water outlet valve body. The inside of the valve body is formed with a conductive liquid outlet hole. The water outlet valve body is rotatably sleeved on the connection part of the water inlet valve body, and one end is against the side of the step part one, and the other end is used to push the outlet water through the circlip. The valve body is defined at the connecting portion.

In the above-mentioned expansion-sealed ceramic spool universal angle valve, a plurality of annular grooves 1 are formed on the outer wall of the water inlet valve body, and O-rings 1 are arranged in the annular grooves 1 .

In the expansion-sealed ceramic spool universal angle valve described above, a step part 2 is formed inside the water inlet valve body, and a limit protrusion 2 is formed on the valve stem, and the valve stem is installed on the water inlet valve. Inside the body, the step part 2 of the water inlet valve body limits the axial movement of the valve stem in the water inlet valve body through the limiting protrusion 2 of the valve stem.

In the expansion-sealed ceramic spool universal angle valve described above, a gasket is also provided between the limiting protrusion 2 and the step portion 2 .

In the above-mentioned expansion-sealed ceramic spool universal angle valve, several annular grooves 2 are formed on the valve stem, and O-rings 2 are arranged in the annular grooves 2.

In the expansion-sealed ceramic spool universal angle valve described above, a filter tip is connected in the body of the water outlet valve.

Compared with the prior art, the utility model has outstanding and beneficial technical effects as follows:

1. The utility model increases the sealing performance of the angle valve by connecting a plastic king ring at the valve body of the water inlet. When the water inlet end of the angle valve is connected to the water pipe, the side of the plastic king ring and the water pipe thread The walls are squeezed against each other, and the plastic ring swells to seal all the gaps at the connection, thus improving the sealing performance of the connection between the water inlet end and the water pipe.

2. The spool of the utility model is a ceramic spool, and the ceramic spool can still operate smoothly and labor-saving after being subjected to more than 500,000 switching operations, and can be used for a long time. The ceramic valve core is anti-aging, wear-resistant, and maintenance-free, which ensures the stability of operation, saves maintenance costs and labor intensity, and so on. At the same time, the aging resistance and wear resistance also make the service life of the ceramic valve core far exceed the service life of other valve cores.

3. The valve body of the utility model is divided into a water inlet valve body and a water outlet valve body. The water inlet valve body can rotate 360 degrees relative to the water outlet valve body. Since the angle of the water inlet valve body cannot be determined each time it is installed on the water pipe, the The corresponding angle can be adjusted by rotating the water outlet valve body, so that the angle of the water outlet can be corrected.

4. The angle valve of the utility model makes the installation of the angle valve more convenient by enhancing the sealing of the water inlet valve body and the function of 360-degree rotation of the water outlet valve body.
