Description

Expandable pigging valve and pressure regulating valve combination device Technical Field

[0001] This utility model relates to the field of pigging valve technology, specifically to an expandable pigging valve and pressure regulating valve combination device. Background Technology

[0002] A pipeline cleaning valve is a new type of valve used as a launching or receiving device for pipeline cleaning tools (such as pigging balls, cup pigs, and foam pigs). It also functions as a general-purpose two-position shut-off ball valve. Widely used in long-distance pipelines for water, oil, and natural gas, it is an indispensable piece of specialized equipment for pipeline construction, cleaning, maintenance, inspection, and management. Using a cleaning valve in conjunction with appropriate cleaning tools makes pipeline cleaning, emptying, cleaning, and sequential transport of media much easier.

[0003] Chinese Patent CN218031669U discloses a cantilevered quick-opening pigging valve. The key technical features include a valve body, a pressure ring located on one side of the valve body, a cantilever connected to the outer wall of the valve body, a connecting rod connected to the cantilever, and a quick-opening valve hinged to one end of the connecting rod. The quick-opening valve has multiple protrusions evenly distributed around its center on its peripheral wall, and multiple stops corresponding to these protrusions are provided on the inner wall of the pressure ring. An annular groove is formed on the end face of the quick-opening valve facing the valve body. A soft and elastic sealing ring is installed inside the annular groove. The end faces of multiple protrusions facing the pressure ring are all raised relative to the end face of the quick-opening door and are inclined relative to the end face of the quick-opening door. The distance from the inclined end faces of the multiple protrusions to the end face of the quick-opening door gradually decreases as the quick-opening door rotates the protrusions between the stop and the valve body. The end faces of the multiple stop are all inclined and can fit against the end faces of the protrusions, which solves the problem of media leakage caused by the inability of the quick-opening door and the valve body to fit tightly in the prior art.

[0004] However, the above technical solution has the following shortcomings: to limit the quick-opening door by simultaneously inserting the limiting component into the pin hole and the limiting hole, it is necessary to ensure that the quick-opening door is just sealed when the limiting component is inserted into the pin hole and the limiting hole at the same time. On the one hand, the processing accuracy requirement is high. On the other hand, after long-term use, after the contact surface wears down, the quick-opening door cannot be effectively sealed when the limiting component is inserted into the pin hole and the limiting hole at the same time. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an expandable combination device for a pigging valve and a pressure regulating valve.

[0006] The technical solution of this utility model: an expandable combination device for a pigging valve and a pressure regulating valve, comprising:

[0007] The main body of the pigging valve has a pressure regulating valve connected to one end;

[0008] The mounting ring seat is connected to the pigging valve body, and a quick-release cover is provided inside the mounting ring seat to seal the pigging valve body;

[0009] A support frame is mounted on a mounting ring seat, with one end of the support frame connected to a quick-release cover.

[0010] A connector, part of which is disposed on the mounting ring seat, and another part of which is disposed on the quick-release cover for connection between the quick-release cover and the mounting ring seat;

[0011] An adjusting component is mounted on a support frame, with one end of the adjusting component connected to a quick-release cover.

[0012] The locking mechanism, which is located on the adjusting part, is used to prevent the quick-release cover from loosening.

[0013] Preferably, the support frame includes a first cantilever and a second cantilever; one end of the first cantilever is rotatably connected to the mounting ring seat, one end of the second cantilever is rotatably connected to the first cantilever, and the other end of the second cantilever is connected to the adjusting member.

[0014] Preferably, the adjusting component includes a mounting cylinder and an adjusting rod; the mounting cylinder is fixedly connected to the second cantilever, the adjusting rod passes through the mounting cylinder and is rotatably connected to the mounting cylinder, one end of the adjusting rod is fixedly connected to the quick-release cover, and the other end of the adjusting rod is fixedly connected to an adjusting handwheel.

[0015] Preferably, the locking mechanism includes a limiting ratchet, a limiting pawl, and a contact spring; the limiting ratchet is fixedly connected to the adjusting rod, the limiting pawl is fixedly connected to the mounting cylinder, one end of the contact spring is fixedly connected to the mounting cylinder, and the other end of the contact spring is fixedly connected to the limiting pawl; the limiting pawl engages with the ratchet teeth of the limiting ratchet under the action of the contact spring.

[0016] Preferably, each set of connectors includes a limiting block and a connecting block; the limiting block is fixedly connected to the inner wall of the mounting ring seat, the connecting block is fixedly connected to the quick-release cover, and the limiting block and the connecting block are compatible.

[0017] Preferably, a sealing ring is connected to the side of the quick-release cap near the main body of the pigging valve, and a sealing groove adapted to the sealing ring is provided in the mounting ring seat.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0019] This utility model, through the cooperative arrangement of the adjusting component and the locking mechanism, achieves two objectives. On the one hand, for applications with relatively low machining precision, rotating the adjusting handwheel drives the quick-release cover and the connecting block to rotate together via the adjusting rod. The rotating connecting block engages with the limiting block, thus completing the seal between the quick-release cover and the pigging valve body. On the other hand, the limiting pawl, under the action of the contact spring, engages with the ratchet teeth of the limiting ratchet wheel to prevent the quick-release cover from rotating in the opposite direction, thereby ensuring the seal between the quick-release cover and the pigging valve body.
