detailed description

In order to make the technical means, creative features, purpose and effect of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

As shown in Figures 1 to 3, a super-durable angle valve that is easy to maintain includes: a hand wheel 1, a switch valve core 3, and a valve body 18. The hand wheel 1 is mounted on the switch valve core 3 through fastening screws. The switch spool 3 is installed in the valve body 18, the valve body 18 is a cross-shaped structure, the right end of the valve body 18 is the valve body water inlet 14, the upper end of the valve body 18 is the water outlet 13, the switch spool 3 One end connected with the handwheel 1 and the valve body 18 are connected with a valve core cap 4 and a valve stem sealing ring 5, and the valve core water inlet 15 of the switch valve core 3 is inserted into the valve body water inlet 14 of the valve body 18. The water outlet 16 of the switch valve core 3 and the water outlet 13 of the valve body 18 are on the same straight line, the lower end of the valve body 18 is provided with a maintenance port 12, and the connection between the maintenance port 12 and the valve body 18 is provided with a spherical water-stop seal 10 , The lower end of the spherical water-stop seal 10 is equipped with a sealing adjustment plug 11 .

The upper end of the connection between the switch spool 3 and the water inlet 14 of the valve body 18 is provided with a 90° switch positioning lug 7 in the inner cavity of the main body, and a 90° switch lug 17 is provided at the lower end of the valve core, and the 90° switch in the inner cavity of the main body Positioning lug 7, spool 90 ° switch lug groove 17 side switch spool 3 and the water inlet 14 end of valve body 18 are connected to be provided with spool water inlet outer sealing ring 8,

The outside of the water outlet 13 is provided with a water outlet threaded head 6, and a water outlet head is installed on the water outlet threaded head 6.

The outside of the valve body water inlet 14 is provided with a valve body water inlet threaded head 9, and the valve body 18 is installed on the pipeline water inlet pipe through the valve body water inlet threaded head 9.

The working principle of the utility model is:

By rotating the hand wheel 1 to control the airtightness and separation between the valve core water outlet 16 of the switch valve core 3 and the spherical water-stop seal 10, the water outlet and water-stop functions of the water outlet 13 of the angle valve are realized. The threaded head of the water inlet of the valve body 9 is connected with the pipeline water pipe, and water enters the valve core water inlet through the valve body water inlet 14. When the handwheel 1 is rotated so that the valve core water outlet 16 of the switch valve core 3 is tightly closed with the spherical water-stop seal 10 on the sealing adjustment plug 11, the water cannot flow out, thereby realizing the water-stop function; 1. When the water outlet 16 on the switch spool 3 is separated from the spherical water-stop seal 10, water will flow out from the water outlet 16 of the spool, and flow out of the main body water outlet 13 through the inner cavity of the main body to realize the function of boiling water.

After N years and N times of use, once the wear between the valve core water outlet 16 on the valve core spherical surface and the spherical water-stop seal 10 increases and water leaks, just use an ordinary small screwdriver or an ordinary coin , by screwing in the seal to adjust the position of the plug 11 and reducing the sealing gap of the spherical surface, the angle valve can be repaired well. There is no need for professionals and professional tools, nor to disassemble the angle valve, nor to replace accessories. The operation is simple and convenient, and saves money. If after many adjustments and maintenances for many years, the sealing gasket is severely worn and can no longer be sealed, only need to easily turn out the maintenance sealing adjustment plug 11, and replace the spherical water-stop seal piece 10 (the spherical water-stop seal 10 is provided as a gift) It can be used continuously, and the angle valve is as good as new, which really achieves the effects of simplicity, convenience, energy saving and saving.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments.
