Description

Technical Field

[0001] The present application relates to the field of valve technology, and in particular to a valve. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. They can be used to control the flow of various fluids such as air, water, mud, and liquid metal. Ball valves are a type of valve and are generally used in pipelines for switching or regulating media. Ball valves in the prior art generally use threaded connections or flanged pipes. Flange connections require bolts to connect, which is complicated to operate. Threaded connections are prone to wear of the threads due to the increase in the number of disassembly and assembly times, affecting the sealing effect. Utility Model Content

[0003] The present application provides a valve, which solves the problems of complex valve connection structure and inconvenient assembly and disassembly in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A valve comprising

[0006] A left valve seat, wherein a valve core is arranged in the left valve seat;

[0007] The right valve seat is disassembled and connected to the left valve seat to form a valve seat;

[0008] The valve stem is used to drive the valve core to rotate;

[0009] The invention is characterized in that: connecting pieces are provided on both the left valve seat and the right valve seat, and the connecting pieces are detachably connected to one end of the left valve seat and the right valve seat. By providing connecting pieces on the left valve seat and the right valve seat, the valve can be conveniently connected to the pipeline through the connecting pieces, or be disassembled from the pipeline, so that when the valve is replaced or repaired, there is no need to disassemble the entire pipeline system on a large scale, and only the connecting piece needs to be separated from the valve, which greatly improves the work efficiency, reduces the wear of the pipeline and the valve during disassembly, and increases the service life of the pipeline.

[0010] Furthermore, a threaded section is provided in the left valve seat, and a mating section is provided on the right valve seat. The threaded section and the mating section cooperate to realize a threaded connection between the left valve seat and the right valve seat. The threaded connection is easy to assemble and disassemble, and can provide strong tensile and torque bearing capabilities, ensuring that the valve will not loosen or leak during operation. At the same time, the disassembly and assembly connection between the left valve seat and the right valve seat can facilitate the assembly of the valve.

[0011] Furthermore, a positioning portion is provided on the surface of the connecting piece, and mounting portions are provided at both ends of the valve seat. The positioning portion and the mounting portion cooperate to achieve the connection between the connecting piece and the valve seat. The cooperation between the positioning portion and the mounting portion can form a stable connection structure, thereby enhancing the overall stability of the valve. At the same time, it ensures that the connecting piece and the valve seat can be accurately aligned during assembly, avoiding installation problems caused by misalignment.

[0012] Furthermore, the mounting portion includes a guide groove, a sealing groove and a positioning groove which are connected in sequence in a stepped manner. When the connecting piece cooperates with the valve seat, the positioning portion moves along the guide groove, the sealing groove and the positioning groove in sequence to achieve the connection between the valve seat and the connecting piece. The design of the guide groove enables the connecting piece to smoothly enter the correct position during assembly, avoiding deviation and misalignment during the installation process. The setting of the sealing groove ensures a close fit between the connecting piece and the valve seat, thereby improving the sealing performance of the valve and effectively preventing fluid leakage. The cooperation between the positioning groove and the positioning portion realizes a stable connection between the valve and the connecting piece, ensuring the stability and reliability of the valve during operation.

[0013] Furthermore, a limit surface is formed on the surface of the connector. When the connector cooperates with the valve seat, the limit surface abuts against the end surface of the valve seat. The existence of the limit surface enables the installer to intuitively determine whether the connector has been correctly installed, thereby simplifying the installation process and improving work efficiency.

[0014] Furthermore, a clamping portion is formed on the surface of the limiting surface, and a clamping groove cooperating with the clamping portion is provided on the valve seat. The clamping portion is clamped in the clamping groove. The cooperating design of the clamping portion and the clamping groove forms a firm clamping connection between the connecting piece and the valve seat, which effectively prevents the valve from loosening and falling off during operation. Through the clamping method, the installer can quickly complete the assembly of the connecting piece and the valve seat without using additional tools or performing complicated operations, thereby simplifying the installation steps and improving work efficiency.

[0015] Furthermore, a sealing member is provided in the clamping groove, and the sealing member abuts against the surface of the clamping portion. By providing the sealing member in the clamping groove, when the clamping portion is clamped in the clamping groove, the sealing member can fit tightly against the surface of the clamping portion, thereby effectively preventing fluid leakage from the connection, improving the sealing performance of the valve, and increasing the friction between the clamping portion and the clamping groove, making the connection more stable and not easy to loosen.

[0016] Furthermore, a positioning hole is provided on the valve seat, and a connecting hole matching the positioning hole is provided on the connecting piece. The positioning piece passes through the positioning hole and is snapped into the connecting hole to achieve the connection between the connecting piece and the valve seat. The positioning piece passes through the positioning hole and is snapped into the connecting hole, forming a stable mechanical connection, which effectively prevents the valve from loosening or falling off due to vibration or impact during operation. At the same time, it has the advantage of a simple connection method. The installer only needs to pass the positioning piece through the positioning hole and snap it into the connecting hole to complete the assembly without using complicated tools or performing cumbersome operations.

[0017] Furthermore, a pressure relief portion is provided on the connecting piece, and a pressure relief port is provided on the pressure relief portion. The pressure relief port is connected to the inner cavity of the valve seat. When the internal pressure of the valve rises abnormally, the excessive pressure can be released in time through the pressure relief port to prevent the valve or pipeline from rupturing or other safety accidents due to excessive pressure. When the valve needs to be inspected or maintained, the medium inside the valve can be easily discharged by opening the pressure relief port, thereby reducing the difficulty and danger of operation.

[0018] Furthermore, threads are provided on the surface of the pressure relief part, and a plug is threadedly connected to the pressure relief port. The pressure relief port is opened and closed by the plug, and the threaded connection ensures a tight fit between the plug and the pressure relief port. This connection method has a high sealing performance and can effectively prevent the medium from leaking from the pressure relief port when the valve is working, thereby ensuring the safe operation of the valve.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0033] like Figures 1 to 5 As shown, this is a valve of the utility model, the main function of which is to connect the pipeline and the valve through a connecting piece, so that when the valve is replaced or repaired, there is no need to dismantle the entire pipeline system on a large scale, and only the connecting piece and the valve need to be separated, which greatly improves work efficiency.

[0034] The utility model provides a valve, comprising a handle 18, a valve stem 19 connected to the handle 18, a valve core connected to the valve stem 19, a left valve seat 12 and a right valve seat 11 that are detachably connected. The left valve seat 12 is connected to the right valve seat 11 to form a valve seat. The valve stem 19 is connected to the valve core and extends out of the left valve seat 12. The handle 18 moves synchronously with the valve stem 19 through a nut. A protective pad 20 is provided on the surface of the handle 18 to improve the comfort of the handle 18. The valve stem 19 drives the valve core to rotate in the valve seat. A threaded section is provided in the left valve seat 12, and an internal thread is provided on the threaded section. A matching section is provided on the right valve seat 11, and an external thread is provided on the matching section. The thread parameters of the two are the same. The threaded section and the matching section cooperate to realize the threaded connection of the left valve seat 12 and the right valve seat 11. At the same time, the detachable connection of the left valve seat 12 and the right valve seat 11 can facilitate the assembly of the valve.

[0035] The two ends of the valve seat are connected with a connector 13, and the connector 13 includes a mounting section 132 and a connecting section 131. The mounting section 132 is provided with a positioning portion 25, and the positioning portion 25 is evenly arranged along the surface of the mounting section 132. The two ends of the valve seat connected to the connector 13 are provided with a mounting portion 22, and the mounting portion 22 includes a guide groove 221, a sealing groove 222 and a positioning groove 223 that are sequentially connected in a stepped manner. The sealing groove 222 and the positioning groove 223 are both provided with a sealing member 21 for improving the matching sealing performance. When the connector 13 is matched with the valve seat, the positioning portion 25 moves along the guide groove 221 to the sealing groove 22 2, then rotate the connector 13 to make the mounting portion 22 reach the positioning groove 223, and finally push the mounting portion 22 to abut against the bottom surface of the positioning groove 223 to achieve the connection between the valve seat and the connector 13. The design of the guide groove 221 enables the connector 13 to smoothly enter the correct position during assembly. The setting of the sealing groove 222 ensures the close fit between the connector 13 and the valve seat, thereby improving the sealing performance of the valve and effectively preventing fluid leakage. The cooperation of the positioning groove 223 and the positioning portion 25 realizes the stable connection between the valve and the connector 13, ensuring the stability and reliability of the valve during operation.

[0036] The mounting section 132 and the connecting section 131 form a limiting surface 24. The surface protrusion of the limiting surface 24 forms a clamping portion 23.
