Background technique
The one-way valve structures of prior art is simple, generally by valve casing and the check valve film Structure composing that is arranged in valve casing of a tubulose.The one-way valve that water purification machine with RO membrane cartridge uses not only requires that one-way valve should possess fluid check function, also require that one-way valve structures is simple, be convenient to assembling, be convenient to connect to the corresponding part on water purification machine, tubing, be beneficial to reduce product cost and labour cost.In addition, one-way valve is generally connected by its other parts of screw thread, and need on screw thread, wrap raw meal belt during installation and seal, troublesome poeration, manufacturing efficiency is low.
Summary of the invention
The object of the invention is: for the problem of prior art, propose a kind of one-way valve with rapid pipe joint simple and reasonable, easy to assembly.
For realizing the object of the present invention, be achieved by the following technical solutions: a kind of one-way valve, include the housing of tubulose, shell one end is water intake, the other end is water outlet, be provided with the valve plate of central opening near one end of water intake in housing, valve plate is provided with the valve head stoping fluid to flow to water intake from water outlet near water outlet one end, valve head is provided with positioning plate near water outlet one end, positioning plate is connected with the valve rod along housing axis, valve rod is arranged with spring, also be provided with in described housing and pass for the valve rod the other end and prop up the fixed block of spring, described water outlet one end is also provided with rapid pipe joint, and described rapid pipe joint includes tube end, seal ring, circular mounting head and snap close, and seal ring is arranged on inside tube end, and the mouth of pipe of tube end is the anticreep mouth that internal diameter reduces from the inside to the outside, circular mounting head is arranged on anticreep mouth, and namely the outer end of circular mounting head is in outside anticreep mouth, and inner end extends inside anticreep mouth, circular mounting head the inner is provided with the multiple arc dops corresponding with anticreep mouth, and multiple arc dop is in anticreep mouth to deviate from, and the madial wall of arc dop is provided with metal card article, snap close to be in outside anticreep mouth and to be stuck in the outer end of circular mounting head.
As preferably: described fixed block is evenly provided with multiple through hole.
Compared with prior art, the invention has the beneficial effects as follows: the one-way valve of this water purification machine only needs successively by after valve head, positioning plate, valve rod, the connection of coiling machine fixed block, fixed block is loaded in housing, the opening at valve head and valve plate center is offseted, again fixed block is fixedly connected with inner walls, easy to assembly, and sound construction.

Embodiment
With reference to the accompanying drawings the specific embodiment of the present invention is made a detailed explanation below.
According to Fig. 1, a kind of one-way valve of the present invention, include the housing 1 of tubulose, housing 1 one end is water intake 101, the other end is water outlet 103, be provided with the valve plate 102 of central opening near one end of water intake 101 in housing 1, valve plate 102 is provided with the valve head 9 stoping fluid to flow to water intake from water outlet near water outlet 103 one end, valve head 9 is provided with positioning plate 8 near water outlet 103 one end, positioning plate 8 is connected with the valve rod 6 along housing 1 axis, valve rod 6 is arranged with spring 7, also be provided with in described housing 1 and pass for valve rod 6 the other end and prop up the fixed block 5 of spring 7, described water outlet 103 one end is also provided with rapid pipe joint, described rapid pipe joint includes tube end 13, seal ring 12, circular mounting 10 and snap close 11, seal ring 12 is arranged on inside tube end 13, and the mouth of pipe of tube end 13 is anticreep mouths 131 that internal diameter reduces from the inside to the outside, circular mounting 10 is arranged on anticreep mouth 131, and namely the outer end of circular mounting 10 is in outside anticreep mouth 131, and inner end extends inside anticreep mouth 131, circular mounting 10 the inners are provided with the multiple arc dops corresponding with anticreep mouth 131, and multiple arc dop is in anticreep mouth 131 to deviate from, and the madial wall of arc dop is provided with metal card article, snap close 11 to be in outside anticreep mouth 131 and to be stuck in the outer end of circular mounting 10.
This one-way valve is generally used for the pure water outlet being connected to RO membrane cartridge bottle, arrives setting value, prevent the water of pressure bucket from completely blowing back into RO film when high-voltage switch gear disconnects at the tank pressure of water purification machine.
Described fixed block 5 is evenly provided with multiple through hole.Described fixed block 5 is circular, and described through hole is uniformly distributed along the center equal angles of fixed block 5.The size of through hole and the quantity of through hole can affect rate of flow of fluid during one-way valve conducting.
