Specific embodiment
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in accompanying drawing
The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here
The mode of applying is limited.Conversely, there is provided these implementation methods are able to be best understood from the disclosure, and can be by this public affairs
The scope opened it is complete convey to those skilled in the art.
According to implementation method of the present utility model, a kind of magnetic valve of integrated unidirectionally controlled function is proposed, as shown in Fig. 2
Including solenoid valve body 1, piston 2, back-moving spring 3, seal plug 4, sealing ring 5, back-up ring 6 and deflector 7, the solenoid valve body
1 includes input duct 8, drain pipe road 11 and cushion chamber 10, and cushion chamber 10 is located at input duct 8 and the lower section of drain pipe road 11, delays
Rush chamber 10 to be connected with input duct 8 by flow-guiding channel 9, cushion chamber 10 is connected through unidirectionally controlled structure with drain pipe road 11.
The cushion chamber 10 goes up greatly small truncated cone-shaped structure for lower, and the liquid into cushion chamber slows down fluid pressure through big round platform
After power, then flowed to through small round platform combing, be conducive to reducing direct impact of the fluid to piston, and keep the stability of flowing.
The flow-guiding channel 9 is made up of the deflector 7 in input duct 11 with the side wall of solenoid valve body 1, deflector 7
From the upper wall of input duct 11 down along at the big round platform for extending cushion chamber 10, the side of deflector 7 forms water conservancy diversion with solenoid valve body 1
Passage 9, its opposite side constitutes the small round platform side wall of cushion chamber 10 and the cavity wall of piston 2.
The unidirectionally controlled structure includes piston 2, back-moving spring 3, seal plug 4, sealing ring 5 and back-up ring 6, the afterbody of piston 2
With guide rod, back-moving spring 3 is set on guide rod, and is resisted against in the groove of seal plug 4, the embedded magnetic valve of the compression of seal plug 4
In the groove of body open end, and it is fixed in solenoid valve body with back-up ring 6, the side wall that seal plug 4 is contacted with solenoid valve body
It is provided with the seal groove for installing sealing ring 5.
Piston 2 is stainless steel, and adds guide rod, for controlling check valve body to be axially moved along back-moving spring 3.It is living
Plug head is sealed with solenoid valve body taper-face contact.Upper piston area is slotted, and is used for fixed reset spring, it is to avoid both move de-
From.
Back-moving spring 3 selects Low rigidity material, is easy to the check valve body can unlatching under the relatively low water flow pressure.
Seal plug 4 selects stainless steel, in the groove of the embedded electromagnetic valve body openend of compression, for fixed piston 2.
Sealing ring 5 selects quality of rubber materials, for sealing, prevents liquid leakage.
Back-up ring 6 selects stainless steel, for fixing seal stifled 5, it is to avoid slip, and conveniently open and inspect maintenance.
When magnetic valve is opened, liquid enters solenoid valve body 1 to the utility model by input duct 8, draws through flow-guiding channel 9
Lead into cushion chamber 10, after the big round platform of cushion chamber slows down Fluid pressure, in the small round platform combing flow direction in buffered chamber, liquid top
Piston 2 is opened, is flowed out from drain pipe road 11 by plunger shaft, the direction of motion of back-moving spring is vertical with magnetic valve inlet and outlet piping, keeps away
Exempt from the direct impact of fluid, better working stability, long service life.Enough in closed electromagnetic valve, liquid backflow can increase work
The lower pressure of plug, prevents liquid from flowing back.
In the case of reversed magnetic valve inlet and outlet connectors, the piston of unidirectionally controlled structure cannot be opened under water flow pressure,
Liquid cannot circulate, so as to avoid the magnetic valve normal open caused by reversed, and then the urea box heating drum caused by continuous heating
Swollen problem.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with
The scope of the claims is defined.
