Example Embodiment

[0012] Reference Figure 1 ~ Figure 4 It can be seen that the stainless steel ball valve of the present invention is composed of a valve seat 1, a valve core 2, a pin 3, a fixed nut 32, a hexagonal bolt 5 and an opening and closing handle 4. The valve seat 1 is a stainless steel cylindrical tube cavity. A round hole is provided on the central body wall, the valve core 2 is installed in the middle of the cavity of the valve seat 1, and there are wear-resistant washers 7, 8 on the left and right sides. A stainless steel washer 6 is also provided between the wear-resistant washer 7 and the hexagonal bolt 5. Then use the hexagonal bolt 5 to screw and squeeze the spool 11 to control the valve core 2 so that the valve core 2 cannot move left and right, and the groove 22 on the valve core 2 is aligned with the hole in the valve seat 1, and then the pin The pin 3 is inserted into the groove 22 on the valve core 2, and the pin 3 is controlled on the valve seat 1 with a fixed nut 32. A w...

Abstract

The invention discloses a ball valve, comprising a valve seat, a valve core, a pin, a fixed nut, a hexagonal bolt and an opening and closing handle. In the groove, there is an opening and closing handle at the upper end. The pin is fixed on the valve seat through a fixing nut. The upper and lower ends of the pin are set flat and at right angles to each other. There is a wear-resistant washer in the middle. A rim is provided under the washer. The beneficial effects of the invention are as follows: it has good sealing performance, can effectively prevent water leakage and prolong the service life.

Description

technical field [0001] The invention relates to a valve, especially a ball valve. Background technique [0002] The sealing performance of various ball valves currently in use is not good. After a period of use, not only air leakage, but also water leakage is caused. On the one hand, water resources are wasted. Rust traces bring a lot of inconvenience to use. Contents of the invention [0003] The object of the present invention is to provide a stainless steel ball valve with good sealing performance and no water leakage. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a stainless steel ball valve, including a valve seat, a valve core, a pin, a fixed nut, a hexagonal bolt and an opening and closing handle, and the valve core is arranged in the lumen of the valve seat, The lower end of the pin is inserted into the groove in the valve core, and there is an opening and closing handle at the upper end. The pin is fix...
