Detailed implementation manners

[0026] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0027] A stainless steel angle valve, as Figures 1 to 7 shown, includes an angle valve body 1, a valve stem 2, a control member, a connecting head 3, a first connecting pipe 4 and a second connecting pipe 5. The first connecting pipe 4, the second connecting pipe 5 and the connecting head 3 are all connected to the angle valve body 1. Preferably, the angle valve body 1, the first connecting pipe 4 and the connecting head 3 are all made of stainless steel materials. It should be noted that this can not only effectively ensure the structural strength of the angle valve body 1, the first connecting pipe 4 and the connecting head 3, but also effectively avoid the release of heavy metal ions into the water, prevent pollution of the water quality, and ensure the health of water use.

[0028] Preferably, the first connecting pipe 4 is welded to the angle valve body 1, and the connecting head 3 is welded to the angle valve body 1, so as to effectively ensure the connection strength between the first connecting pipe 4 and the angle valve body 1 and the connection strength between the connecting head 3 and the angle valve body 1.

[0029] It should be noted that the second connecting pipe 5 is preferably made of stainless steel material, which can effectively prevent heavy metal ions from being released into the water, further prevent water quality pollution, and ensure the health of water use.

[0030] A connection port 14 is provided on the angle valve body 1. The first connecting pipe 4 has a connection portion 15. A first positioning step 13 is provided on the angle valve body 1. The end face of the connector 3 abuts against the step surface of the first positioning step 13, so as to ensure the relative stability between the angle valve body 1 and the connector 3, facilitate the operator to weld the two, make the welding work more efficient, and further improve the structural stability.

[0031] The first connecting pipe 4 and the connection portion 15 are integrally provided. The connection portion 15 is inserted into the connection port 14. A second positioning step 16 is provided on the first connecting pipe 4. The step surface of the second positioning step 16 abuts against the outer surface of the angle valve body 1, so as to ensure the relative stability between the angle valve body 1 and the first connecting pipe 4, facilitate the operator to weld the two, make the welding work more efficient, and further improve the structural stability.

[0032] The control member is arranged inside the angle valve body 1. The first connecting pipe 4 is provided with a water inlet 6, and the second connecting pipe 5 is provided with a water outlet 7. The valve rod 2 can control the on-off between the water inlet 6 and the water outlet 7 through the control member. In this embodiment, the control member includes a ball core 8. The ball core 8 is rotatably arranged inside the angle valve body 1. The valve rod 2 is rotatably arranged inside the connector 3, and the inner end of the valve rod 2 is connected to the ball core 8. A communication hole 9 is provided on the ball core 8. When the valve rod 2 is rotated to drive the ball core 8 to rotate, the communication hole 9 can communicate the water inlet 6 and the water outlet 7. Specifically, as the ball core 8 rotates, the ball core 8 can cut off the connection between the water inlet 6 and the water outlet 7.

[0033] As another solution, the control member includes a moving valve plate and a static valve plate. The static valve plate is arranged inside the angle valve body 1. The moving valve plate is rotatably arranged on the static valve plate. A first communication hole 9-1 is provided on the static valve plate, and the first communication hole 9-1 is communicated with the water inlet 6. A second communication hole 9-2 is provided on the moving valve plate, and the second communication hole 9-2 is communicated with the water outlet 7. The moving valve plate is connected to the valve rod 2. When the moving valve plate rotates, the first communication hole 9-1 and the second communication hole 9-2 are communicated, and at this time the water inlet 6 and the water outlet 7 are communicated. On the contrary, when the moving valve plate completely covers the first communication hole 9-1, the connection between the water inlet 6 and the water outlet 7 is cut off at this time.

[0034] An installation port 10 is provided on the angle valve body 1. The second connecting pipe 5 is threadedly connected to the installation port 10. The ball core 8 can pass through the installation port 10, that is, the second connecting pipe 5 can be disassembled and assembled by rotating the second connecting pipe 5.

[0035] The inner end of the second connecting pipe 5 is provided with a first valve seat 11. A second valve seat 12 is arranged inside the angle valve body 1. The first valve seat 11 and the second valve seat 12 cooperate to limit the ball core 8. The end face of the first valve seat 11 abuts against the outer side wall of the ball core 8, and the end face of the second valve seat 12 abuts against the outer side wall of the ball core 8, so as to ensure the stability of the ball core 8.

[0036] It should be noted that during installation, the second valve seat 12, the ball core 8 and the first valve seat 11 are sequentially placed into the angle valve body 1 from the installation port 10, and then the second connecting pipe 5 is threadedly connected to the installation port 10, so that the end face of the first valve seat 11 abuts against the outer side wall of the ball core 8, and the end face of the second valve seat 12 abuts against the outer side wall of the ball core 8, thus completing the installation.

[0037] The second connecting pipe 5 is provided with a third positioning step 17. The step surface of the third positioning step 17 abuts against the outer surface of the angle valve body 1, so as to ensure the relative stability between the second connecting pipe 5 and the angle valve body 1, facilitate the installation of the second connecting pipe 5, and further improve the structural stability.

[0038] The outer end of the valve stem 2 is connected with a handle 18. A limiting protrusion 19 is arranged on the outer side wall of the connecting head 3. At least two limiting protrusions 20 are arranged on the inner side wall of the handle 18, and the two limiting protrusions 20 are arranged oppositely. The limiting protrusion 19 is located between the two limiting protrusions 20. When the handle 18 is rotated, it will drive the two limiting protrusions 20 to rotate synchronously. The side wall of the limiting protrusion 19 is used to limit the two limiting protrusions 20. After one of the limiting protrusions 20 abuts against the limiting protrusion 19, the rotation of the handle 18 is restricted, that is, by restricting the rotation angle of the handle 18, the rotation angles of the valve stem 2 and the ball core 8 are further restricted, which is convenient for the user to control the opening and closing of the angle valve.

[0039] The valve stem 2 passes through the connecting head 3. A sealing ring 21 is arranged between the valve stem 2 and the connecting head 3. The sealing ring 21 is used to seal between the valve stem 2 and the connecting head 3, so as to ensure the sealing performance between the two.
