Description
Technical Field
The utility model relates to a special U-shaped relief pressure valve of integrated water route board relates to the commercial water dispenser of water treatment trade, the field of domestic water purifier. And more particularly to the application field of using the pressure reducing valve on the water supply system of city tap water and domestic water and the integral water board of the water purifier.
Background
The inside of traditional purifier is usually connected waterway system with PE pipe and various joints, adopts joint and PE union coupling between each filter core to install various controlling means as on rivers passageway: the water-way system comprises a pressure reducing valve, a water inlet electromagnetic valve, a waste water electromagnetic valve, a high-low pressure switch, a check valve and the like, thereby achieving the purpose of controlling the water-way system. With the continuous development of water purification equipment, the functions of the water purification equipment are more and more, and the water flow pipelines staggered with each other in the water purification equipment are more and more complex. Because the water route of traditional purifier is formed by water pipe and articulate, therefore there are two technical insufficiencies: firstly, the pipeline system is complex, and the assembly links are many; secondly, the pipeline has many connecting points, and the system is easy to cause the hidden trouble of water leakage.
The integrated water channel plate is a part integrating all inflow and outflow water channel pipelines of the water purifier as the name implies, and almost all pipelines are designed into a module which is integrally combined. The integrated water route board can reduce the pipeline quantity of water purifier by a wide margin, reduces the water leakage point, reduces the product volume, reduces the risk of leaking.
But the integrated waterway plate is difficult to develop: the technology relates to various technologies such as materials, moulds, hydromechanics, hydrochemistry, electrochemistry and the like, and the production and the manufacture of the material are difficult.
The application of the pressure reducing valve on the integrated waterway plate can stabilize water pressure and prevent water hammer impact, and can also reduce the design value of the compressive strength of the integrated waterway plate, reduce the manufacturing cost and prolong the service life of the whole machine. How to design a pressure reducing valve integrated with a waterway plate is a new subject faced by the pressure reducing valve.
The conventional pressure reducing valve has two types, and the two ends of the conventional pressure reducing valve are provided with a jaw quick-insertion structure, as shown in fig. 7 and 8, in detail, fig. 6 of a partial enlarged view of fig. 8, and the number 31 is a jaw. The traditional water purifier pressure reducing valve adopts a quick connection mode, and the structure of the traditional water purifier pressure reducing valve is mostly in the form that a clamping jaw 31 is matched with a sealing ring 33. The water pressure arrow 37 indicates the water pressure direction, the PE pipe 30 is pushed outwards by the water pressure, and the flange 36 on the claw 31 is clamped on the PE pipe 30 through the steel sheet barb 32 on the claw 31 under the action of the backstop inclined plane 34, so that the pipeline is prevented from being pulled out. In mass production of water purifiers, the pipe wall of the PE pipe 30 is easily scratched by the steel sheet barbs 32 on the claws 31 (there are micro scratches) to cause water leakage on the sealing surface of the sealing ring 33, which is why many water purifiers on the market are prone to have the problem of water leakage at the joint.
