Description

Technical Field

[0001] The utility model relates to the technical field of stop valves, in particular to a copper stop valve which is easy to replace. Background Art

[0002] Globe valves are commonly used to control the flow of fluids in pipelines, either closing or opening the passage of fluids. They are widely used in industrial, domestic, and commercial applications, and are commonly found in water and gas pipelines, as well as in the chemical industry. Globe valves control the flow of fluids by moving a valve core or rotating a valve disc up and down, thereby closing or opening the pipeline.

[0003] When the existing stop valve is connected to the pipeline, it is necessary to use several bolts to connect the stop valve connection end and the flange at the pipeline connection end, which is troublesome to install. When the stop valve needs to be replaced, many bolts need to be removed, which is time-consuming and labor-intensive. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing stop valve needs to be installed or disassembled with several bolts during installation and replacement, which is time-consuming and labor-intensive.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is a copper stop valve that is easy to replace, including a stop valve body, the stop valve body includes a valve body, and pipe connecting ends are provided at both ends of the valve body. A hexagonal boss is fixed on the outside of the pipe connecting end, and a connecting sleeve is slidably provided on the outside of the pipe connecting end. A hexagonal limiting groove is provided on one side of the connecting sleeve, and a threaded groove is provided on the inside of the connecting sleeve. One end of the pipe connecting end is located in the connecting sleeve and a delivery pipe is provided. A flange is fixed at one end of the delivery pipe. A pair of clamping structures are provided between the delivery pipe and the pipe connecting end, and a threaded tooth structure is fixed on the outside of one end of the clamping structure.

[0006] As a further solution of the present invention, the thread teeth on the outer side of the pressing structure and the thread grooves on the inner side of the connecting sleeve are engaged with each other.

[0007] As a further solution of the present invention: a flange is clamped between the pipe connection end and the pressing structure to fix the position of the delivery pipe.

[0008] As a further solution of the utility model: a valve cover is fixed to the top of the valve body by bolts, a valve stem is provided on the middle of the valve cover by a threaded rotation, a hand wheel is fixed to the top bolt of the valve stem, and a pressure cap is provided in the middle of the valve stem.

[0009] As a further solution of the present invention: a communication port is provided inside the valve body, and a valve core is provided on the bottom end of the valve stem which is located in the communication port and is rotatable therein.

[0010] As a further solution of the present invention: the inner radius of the compression structure is equal to the outer radius of the delivery pipe, and a handle is fixed to the side of one end of the compression structure to facilitate the rotation of the compression structure.

[0011] As a further solution of the present invention, the length of the connecting sleeve is smaller than the length of the hexagonal boss, so that when the delivery pipe is disassembled, one end of the connecting sleeve will not exceed one end of the pipe connection end.

[0012] Compared with the prior art, the advantages of the present invention are as follows: the present patent adds a connecting sleeve and a clamping structure. When disassembling the valve body, it is only necessary to rotate the clamping structure to separate it from the connecting sleeve, and then slide the connecting sleeve to remove the delivery pipe, which makes replacing the stop valve simple and quick; and through this structure, the installation time of the delivery pipe can be saved.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides a technical solution for solving the existing problems raised in the background technology.

[0022] Combined with attachment Figure 1-4 It can be known that the device includes a stop valve body, which includes a valve body 1. Both ends of the valve body 1 are provided with pipe connecting ends 1.1. A hexagonal boss 1.2 is fixed on the outside of the pipe connecting end 1.1. A connecting sleeve 2 is slidably provided on the outside of the pipe connecting end 1.1 to cooperate with a clamping structure 4. A hexagonal limiting groove 2.1 is provided on one side of the connecting sleeve 2 to prevent the connecting sleeve 2 from rotating. A threaded groove is provided on the inside of the connecting sleeve 2. One end of the pipe connecting end 1.1 is located in the connecting sleeve 2 and is provided with a delivery pipe 3. A flange 3.1 is fixed at one end of the delivery pipe 3. A pair of clamping structures 4 are provided between the delivery pipe 3 and the pipe connecting end 1.1 to fix the position of the delivery pipe 3. A threaded tooth structure is fixed on the outside of one end of the clamping structure 4.

[0023] The threaded teeth on the outside of the clamping structure 4 are engaged with the threaded grooves on the inside of the connecting sleeve 2; the flange 3.1 is clamped between the pipe connecting end 1.1 and the clamping structure 4 to fix the position of the delivery pipe 3; a valve cover 5 is fixed to the top of the valve body 1 by bolts, and a valve stem 6 is provided on the middle part of the valve cover 5 for rotation by thread, and a handwheel 7 is fixed to the top bolt of the valve stem 6, and a pressure cap 8 is provided in the middle of the valve stem 6; a connecting port 1.3 is provided inside the valve body 1, and a valve core 9 is provided for rotation at the bottom end of the valve stem 6 located in the connecting port 1.3; the inner radius of the clamping structure 4 is equal to the outer radius of the delivery pipe 3, and a handle 4.1 is fixed to the side of one end of the clamping structure 4 to facilitate the rotation of the clamping structure 4; the length of the connecting sleeve 2 is less than the length of the hexagonal boss 1.2, so that when the delivery pipe 3 is disassembled, one end of the connecting sleeve 2 will not exceed one end of the pipe connecting end 1.1.

[0024] The working principle of this application is: when installing the stop valve, first align one end of the delivery pipe 3 with the pipe connecting end 1.1, then slide the connecting sleeve 2 so that the connecting sleeve 2 is located outside one end of the delivery pipe 3, and then clamp a pair of clamping structures 4 on the outside of the delivery pipe 3, and then rotate it so that the threaded teeth on the outside of the clamping structure 4 can engage with the threaded grooves on the inside of the connecting sleeve 2. During the rotation process, the pipe connecting end 1.1 and the clamping structure 4 will squeeze the flange 3.1, thereby fixing the position of the delivery pipe 3. When disassembling, you only need to rotate and unscrew the clamping structure 4, and then slide the connecting sleeve 2 so that one end of the connecting sleeve 2 does not exceed one end of the pipe connecting end 1.1, and then directly remove the stop valve body.

[0025] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
