Description

Technical Field

[0001] The utility model relates to the technical field of one-way valves, and more specifically to a quick-insertion spring one-way valve. Background Art

[0002] In the gas pipeline system of natural gas engines, the one-way valve plays a vital role. It is responsible for controlling the one-way flow of gas and preventing backflow. Traditionally, spring-loaded one-way valves are widely used in such systems, but in practical applications, they face a series of challenges.

[0003] After the one-way valve is assembled to the quick-insert nylon tube, it is connected to the counterpart, making the connection process with the counterpart complicated and cumbersome, which not only increases the assembly time and cost, but also easily introduces assembly errors, thus affecting the performance of the one-way valve; after the traditional spring-type one-way valve is assembled into the nylon tube, its performance test often needs to be carried out in the assembled state, which not only increases the complexity of the test, but also may lead to inaccurate test results, because in the assembled state, the performance of the one-way valve may be interfered or affected by other components, making the test results unable to truly reflect the actual performance of the one-way valve; furthermore, due to the complex assembly method of the traditional one-way valve and the nylon tube, and the existence of multiple intermediate links, the reliability of the entire production process is challenged, these intermediate links not only increase the uncertainty of production, but also may introduce new quality risks, such as scratches and deformation during the assembly process, which may lead to an increase in the scrap rate of the product, thereby increasing the processing cost. Therefore, we make improvements on this and propose a quick-insert spring one-way valve.

[0004] For example, a Chinese patent (publication number CN217784517U) discloses an integrated pipeline with a one-way ventilation function, including a nylon pipeline, a one-way valve, and a quick-connect plug. The one-way valve and the quick-connect plug are respectively sealed and pressed on both ends of the nylon pipeline; the one-way valve is a metal one-way valve; the quick-connect plug is a nylon material quick-connect plug; the one-way valve includes a valve body, a cover plate, a spring, and a dust cap. The valve body is clamped with the dust cap, and the spring abuts between the cover plate and the dust cap; the dust cap can rotate 60° circumferentially around the valve body; the quick-connect plug is a right-angle quick-connect plug, which is connected to the metal pipeline of the transmission system component through an internal thread section.

[0005] The technical problem to be solved by the embodiment of the utility model is that after the one-way valve is assembled into a quick-insert nylon tube and connected to the counterpart, the connection process with the counterpart is complicated and cumbersome, detection is difficult, product quality control is difficult and the processing cost is high.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A quick-insert spring one-way valve comprises: a valve body, one end of which is fixedly connected to a male connector, and the male connector and the valve body are integrally arranged. The present application integrates the valve body and the male connector together by manufacturing the valve body and the male connector as a whole, thereby greatly simplifying the assembly process and reducing the assembly man-hours. This not only speeds up the operation speed of the production line, but also reduces labor costs, thereby significantly improving manufacturing efficiency. The integrated design reduces intermediate links and assembly steps, thereby reducing assembly errors and defective product rates. At the same time, the performance of the one-way valve can be tested separately, which improves the accuracy and reliability of the test and further reduces quality risks.

[0008] As an improvement of the utility model, a limiting convex ring is fixedly provided on the outer surface of the male connector, and slopes are provided on both sides of the limiting convex ring and the end of the male connector away from the valve body. Through the provided limiting convex ring, when the limiting convex ring is assembled with the existing female connector, the limiting convex ring can limit the male connector during the assembly process, that is, when the limiting convex ring is blocked during the assembly process of the male connector, it has been installed in place, avoiding damage to the connection caused by excessive tightening.

[0009] As an improvement of the utility model, the interior of the valve body is sequentially provided with a first channel, a second channel and a third channel, the diameters of the first channel, the second channel and the third channel are increased successively, and the first channel is located between the male connector and the second channel.

[0015] As an improved manner of the utility model, a plurality of through holes are provided on the spacer.

[0016] As an improvement of the utility model, a riveted end is provided at one end of the valve body away from the male connector, a valve cover is provided between the third channel and the riveted end, one end of the valve cover contacts the riveted end, and the other end of the valve cover passes through the riveted end.

[0017] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:
