Description

Technical Field

[0001] This utility model relates to the field of one-way valve technology, specifically a durable one-way valve. Background Technology

[0002] A check valve is a device that allows fluid to flow only through the inlet, but prevents the medium from flowing back through the outlet. Check valves come in two types: straight-through and right-angle. The choice depends on the management requirements. Right-angle check valves are easy to install and remove because the valve core can be installed at a corner.

[0003] The current one-way valve CN201520416613.3 has the following drawbacks: when water enters the inlet, the one-way valve core experiences unbalanced forces, which may cause the end face to tilt. In this case, the one-way valve core abuts against the guide flap, which provides support to the one-way valve core, preventing further tilting. Water then flows out through the gap between the guide flaps. When water no longer enters the inlet, the guide flap guides the one-way valve core back to its original position, ensuring that the spring force can guide the one-way valve core to cover the one-way valve port again. However, this design has shortcomings: the existing equipment has poor protection and poor installation stability. Furthermore, the piston positioning single-spring structure has poor durability and is prone to damage. Therefore, a more durable one-way valve is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a durable one-way valve to solve the problems mentioned in the background art, such as poor protection of one-way valves, poor installation stability, poor durability of piston positioning single spring structure, and easy damage.

[0006] Preferably, the connecting sleeve is installed in a rotating threaded connection with the splicing pipe via a rotating ring, the movable collar is fixedly connected to the connecting sleeve via a locking knob, and the support frame is distributed perpendicularly to the movable collar.

[0007] Preferably, the movable collar is slidably connected to the connecting sleeve via a ball bearing, and the support frame is elastically connected to the support rod via a second spring.

[0008] Preferably, the protective sleeve is made of a mesh-wrapped rubber material, and the protective sleeve is positioned to wrap around the main pipe.

[0009] Preferably, one end of the piston block has an arc-shaped structure, and the piston block is elastically telescopically connected to the main pipe through a first spring and a telescopic rod, wherein the first spring and the telescopic rod are distributed in a ring position on the piston block.

[0010] Preferably, the liquid inlet is distributed in a ring position on the piston block, and the liquid inlet is sealed to the main pipe by a sealing gasket, the sealing gasket being a funnel structure.

[0011] Compared with the prior art, the advantages of this utility model are: the durable one-way valve can be protected by wrapping the main pipe with a protective sleeve, which provides excellent protection.
