Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a detachable valve pipe fitting. Background Art

[0002] Valves are control components in fluid delivery systems, performing functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow and pressure relief. Valves typically consist of a valve body, bonnet, seat, opening and closing components, actuating mechanisms, seals, and fasteners. The valve's control function is achieved by the actuating mechanism or fluid driving the opening and closing components to rise, fall, slide, rotate, or rotate, thereby changing the flow area.

[0003] In the prior art, existing valve pipe fittings are usually installed by bolt connection or plug-in connection when they are connected, so that the valve pipe fittings are easy to disassemble when they need to be replaced or repaired. However, when the valve pipe fittings are installed by plug-in connection, the connection of the valve pipe fittings is not firmly connected, which leads to a poor seal at the connection of the valve pipe fittings. After being impacted by water flow for a long time, the connection of the valve pipe fittings will become loose, resulting in water leakage. When the valve pipe fittings are connected by bolts, supporting tools are required to assist in disassembly and assembly, which has great limitations and reduces the convenience of disassembly and assembly. To this end, we propose a detachable valve pipe fitting to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when the valve pipe fitting is installed by plugging, the connection of the valve pipe fitting is not firmly connected, which leads to the valve pipe fitting connection being not tightly sealed.

When the valve pipe fitting is connected by bolts, supporting tools need to be used to assist in disassembly and assembly, which has great limitations and reduces the convenience of disassembly and assembly.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example

[0030] Reference Figures 1-4 , a detachable valve pipe fitting, comprising:

[0031] Valve body 1;

[0032] There are two pipes 5, and the ends of the two pipes 5 close to each other are respectively plugged into the left and right ends of the valve body 1;

[0033] There are two sealing rings 6, which are fixedly bonded to the ends of the two pipes 5 that are close to each other;

[0034] Two limiting inner rings 7 are provided, and the limiting inner rings 7 are fixedly sleeved on the corresponding pipes 5;

[0035] The locking assembly is provided in two pieces, and the locking assembly includes: a limiting outer ring 9 and a locking ring 10. The limiting outer ring 9 is sleeved on the corresponding pipe 5, and the limiting outer ring 9 cooperates with the corresponding limiting inner ring 7. One end of the locking ring 10 is rotatably connected to one end of the limiting outer ring 9. The locking ring 10 is sleeved on one end of the valve body 1, and the locking ring 10 is threadedly connected to one end of the valve body 1.

[0036] By means of the above structure: by setting a locking assembly, the valve body 1 and the two pipes 5 can be quickly connected and fixed, and the stability after connection is high, no supporting tools are required for auxiliary operation, the limitations are small, the operation is convenient and fast, and the disassembly and assembly efficiency between the pipe 5 and the valve body 1 is improved, and the practicality is strong.

[0037] As a preferred solution of the present invention, slots 3 are provided at the left and right ends of the valve body 1. The ends of the two pipes 5 close to each other can be detached and inserted into the two slots 3 respectively, and one side of the sealing ring 6 is in contact with the inner wall of the corresponding slot 3. By providing the slots 3, the pipes 5 and the valve body 1 can be quickly and accurately connected.

[0038] As a preferred solution of the present invention, a positioning rod 8 is welded to one side of the limiting inner ring 7, and a positioning groove 4 is provided on the top inner wall of the two slots 3. One end of the positioning rod 8 can be detached and inserted into the corresponding positioning groove 4. By inserting the positioning rod 8 into the positioning groove 4, the pipe 5 can be restricted from rotating after being inserted between the pipe 5 and the valve body 1.

[0039] As a preferred solution of the present invention, the left and right ends of the valve body 1 are both provided with external threads 2, and the inner walls of the two locking rings 10 are both provided with internal threads 11. The external threads 2 are threadedly connected to the corresponding internal threads 11. Through the threaded connection between the external threads 2 and the internal threads 11, the locking ring 10 and the valve body 1 can be quickly locked and fixed.

[0040] As a preferred solution of the present invention, multiple force handles 12 are welded at equal intervals on the outside of the locking ring 10. By providing the force handles 12, it is convenient for personnel to operate the locking ring 10 to rotate, and it can ensure that the locking ring 10 locks and fixes the valve body 1 and the pipeline 5, and ensures the installation sealing of the valve body 1 and the pipeline 5.

[0041] As a preferred solution of the present invention, multiple T-shaped sliders are welded on one side of the locking ring 10, and an annular groove is opened on one side of the limiting outer ring 9. The multiple T-shaped sliders are all slidably connected in the annular groove. Through the sliding limiting cooperation between the T-shaped sliders and the annular groove, stable rotation between the locking ring 10 and the limiting outer ring 9 can be achieved.

[0042] The working principle of the present invention is as follows: when in use, first connect the two pipes 5 with the slots 3 at both ends of the valve body 1, and at the same time, connect the positioning rod 8 with the positioning groove 4 to limit the position, and then operate the force-adding handle 12 to rotate the locking ring 10. At this time, through the threaded connection between the external thread 2 and the internal thread 11, the locking ring 10 can drive the limiting outer ring 9 to be locked and fixed on the valve body 1. When the limiting outer ring 9 moves, it can contact the limiting inner ring 7 and drive the pipe 5 to approach the valve body 1. At this time, the pipe 5 and the valve body 1 will squeeze the sealing ring 6, and finally the valve body 1 and the pipe 5 can be quickly installed and fixed. The valve body 1 and the pipe 5 are highly stable after connection, and no supporting tools are required for auxiliary operation. The limitation is small, the operation is convenient and quick, and the disassembly and assembly efficiency between the pipe 5 and the valve body 1 is improved, and the practicality is strong.
