[0017] The present invention will be described in further detail below with reference to the accompanying drawings.
[0018] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this description, those skilled in the art may make creative modifications to the embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
[0019] The utility model is a ball valve with a locking function and a male and female threaded joint, which solves the technical problems in the prior art. The overall idea is as follows:
[0020] Example 1:
[0021] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4A ball valve with a locking function and an internal and external threaded joint includes a pipe body 1, a valve ball 3 and a valve stem 9. The pipe body 1 is made of copper. The valve ball 3 is rotatably embedded in the pipe body 1. The valve stem 9 is arranged on the top of the valve ball 3 and extends out of the pipe body 1. A connecting cover is integrally formed above the outer wall of the valve stem 9. The connecting cover can be rotatably covered at the interface at the top of the pipe body 1. A locking screw 12 is screwed on the interface at the top of the pipe body 1, and the locking screw 12 extends to the upper surface of the connecting cover. A handle is provided on the top of the valve stem 9. 10. The upper surface of the connecting cover of the outer wall of the valve stem 9 is provided with a rotating cover 11 through a damping shaft. The rotating cover 11 blocks the locking screw 12 exposed on the upper surface of the connecting cover. With the cooperation of the locking screw 12, the connecting cover can be limited so that it and the valve stem 9 and the handle 10 cannot rotate. When the locking screw 12 is removed from the connecting cover and the pipe body 1, the valve stem 9 and the handle 10 can be rotated. The locking screw 12 needs to be locked with a special hexagonal wrench, and the rotating cover 11 is ensured to prevent accidental opening by non-related personnel.
[0022] In a specific implementation, a through hole is formed at one end of the handle 10 away from the valve stem 9 for tying an iron wire therein to further fix the handle 10 .
[0023] In specific implementation, sealing gasket 1 2 and sealing gasket 2 4 are provided on both sides of the valve ball 3 to match its outer wall and the inner wall of the pipe body 1 to prevent the medium from leaking at the contact point between the valve ball 3 and the pipe body 1, thereby ensuring the sealing effect on both sides of the valve ball 3.
[0024] During specific implementation, a union end 5 is provided at one end of the pipe fitting body 1, and a union cap 7 is provided at the end of the union end 5 away from the pipe fitting body 1. The union end 5 and the union cap 7 can be quickly assembled or disassembled with other pipes or pipe fittings by means of threaded connection, etc., making it convenient to select union caps 7 of different specifications to adapt to pipes of different diameters.
[0025] During specific implementation, an O-ring 1 6 is provided between the union end 5 and the pipe body 1, and an O-ring 2 8 is provided at the interface between the outer wall of the valve stem 9 and the top of the inner wall of the pipe body 1. The O-ring 1 6 prevents the medium from leaking from the connection gap between the union end 5 and the pipe body 1, and the O-ring 2 8 is used to seal the gap between the valve stem 9 and the pipe body 1.
[0026] During specific implementation, the handle 10 and the valve stem 9 are connected by a one-way dovetail groove structure to prevent the product structure from being damaged by violent disassembly by non-professionals.
[0027] The above description of the embodiments is to facilitate ordinary technicians in this technical field to understand and use the present invention. It is obvious that those familiar with the technology in this field can easily make various modifications to the embodiments and apply the general principles described herein to other embodiments without having to engage in creative work. Therefore, the present invention is not limited to the above embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
