Description

Angle valve assembly with elbow

Technical Field

The utility model belongs to the technical field of the valve, a angle valve is related to, especially, relate to an angle valve subassembly of area return bend.

Background

An angle valve is a valve widely used in industry and civil, and is also called a triangular valve, an angular valve or a dog-angle water valve. In the design of pipelines, due to the problem of pipeline arrangement, a bent pipe is often required to be connected with an angle valve. The traditional connection mode of the angle valve and the elbow is that the angle valve and the elbow are directly connected by threads, and raw material is required to be wound at the threaded connection part to ensure the sealing performance. The connection mode can obtain good connection firmness, is not easy to be randomly disassembled by other people, has higher safety, is more troublesome to operate, and is particularly inconvenient to screw by using a wrench in a narrow place. To connecting inconvenient problem, appear on the market and adopt the rand of taking the jack catch to carry out the mode of high-speed joint, insert the back when the pipe fitting, sting on the lateral wall of pipe fitting by the jack catch on the rand, and make the pipe fitting can't be extracted.

Although the quick connection of the elbow can be realized by adopting the quick-insertion structure, the risk that the elbow can be easily detached by other people by using a tool also exists. The utility model discloses a withdrawal tool of quick connector for chinese patent application No. 201720082997.9, it includes the tool body, and the tool body is made by hard material, and the tool body is including being massive connecting portion, has two convex clamping parts that set up relatively on the connecting portion, forms the holding tank between two clamping parts, has convex dog one and dog two that set up relatively on two liang of opposite one sides of clamping part. The tool body is mounted on the joint, the first stop block and the second stop block enable the clamping teeth on the gear ring to be kept in a spread state, and a user can rapidly finish the disassembly of the joint and the connecting pipe by respectively holding the joint and the connecting pipe with two hands. That is, the structure using the quick-insertion type is inferior in safety compared to the threaded connection.

Disclosure of Invention

The utility model aims at the above-mentioned problem that prior art exists, provide a take angle valve subassembly of return bend, solved the not enough problem of security when return bend high-speed joint.

The purpose of the utility model can be realized by the following technical proposal:

In the angle valve assembly with the bent pipe, the two convex blocks are symmetrically distributed on the outer peripheral surface of the ring body, and the two convex blocks are provided with grooves.

Two lugs are symmetrically distributed on the outer peripheral surface of the ring body, grooves are formed in the lugs, the locking ring can be connected with other corresponding accessories when the pipeline is connected, the function of preventing the bent pipe from being detached from the valve body by other tools can be achieved through the locking ring, and the dual-purpose function of one object is achieved.

In the angle valve assembly with the bent pipe, the outer peripheral surface of the ring body is further provided with an installation identification part, and the installation identification part is positioned between the two convex blocks.

Because the locking ring can be connected with other corresponding accessories by arranging the convex block with the groove on the ring body, the angle between the two convex blocks and the valve body is also required when the elbow is inserted into the water inlet, therefore, the installation identification part is arranged on the outer peripheral surface of the ring body, and the installation identification part is aligned with the corresponding position on the valve body to be used as the reference when the elbow is inserted into the water inlet, thereby ensuring that the angle between the two convex blocks and the valve body can be used when being connected with other corresponding accessories.

In the angle valve assembly with the bent pipe, the sealing element is made of rubber, the sealing element is of a sleeve-shaped structure embedded in the water inlet, and the outer peripheral surface of the sealing element is abutted against the inner peripheral wall of the water inlet.

Compared with the prior art, the angle valve assembly with the elbow pipe realizes the quick connection of the elbow pipe and the angle valve through the arrangement of the clamping ring; and the lock ring sleeved on the elbow abuts against the annular shoulder on the nut, so that the elbow cannot be detached by tools by others, and the safety in use is well improved. In addition, the groove structure on the locking ring can be connected with other corresponding accessories, so that the dual-purpose function of one object is realized, the structure is optimized, and the production cost is low.
