Description
Technical field
The utility model relates to jetting machine technical fields more particularly to a kind of jetting machine overflow valve overflow to shut down
Structure.
Background technique
Jetting machine is that high-pressure plunger pump is made to generate high pressure water to rinse the machine of body surface by power device.
It can remove dirt, wash away, and achieve the purpose that cleaning object surface.It is high when overflow valve works in existing jetting machine
Pressure water flow acts directly on spool, and spring has to be larger than water flow to the power of spool to the power of spool, is easy to influence the stabilization of spool
Property.
Utility model content
(1) technical problems to be solved
The purpose of this utility model seeks to overcome disadvantages mentioned above, it is desirable to provide a kind of jetting machine overflow valve overflow stops
Machine structure.
(2) technical solution
In order to achieve the above objectives, structure, including overflow valve sheet are shut down in the jetting machine overflow valve overflow of the utility model
Body, and the switching mechanism with overflow valve body fits；
It further include total valve module, total valve module includes the shell connecting with overflow valve body, and the shell center is set
It is equipped with main valve core assembly, is provided with reset spring between main valve core assembly end and shell；
Relief valve spool component, relief valve spool component one end and total valve core are provided in the overflow valve body
The end of component is corresponding, and the other end of relief valve spool component is provided with push-rod assembly, and the relief valve spool component is along overflow
Valve body inner wall transverse shifting, and push-rod assembly is driven to be acted accordingly.
Further, the push-rod assembly includes push rod fixing end, and the mandril across the push rod fixing end；The mandril
It is socketed push rod spring.
Further, the switching mechanism includes switch housing, and microswitch, the microswitch are provided in switch housing
Triggering end one sliding block is set, the end of the sliding block is corresponding to the end of the mandril.
Further, sliding block one end opposite with mandril is wedge surface.
Further, the end of the main valve core assembly is in boss-shaped, and the relief valve spool component is provided with convex with this
The corresponding inclined surface in the end of mesa-shaped.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has the advantage that the jetting machine of the application overflows
It flows valve overflow and shuts down structure, the movement of overflow valve internal structure is realized using the variation of hydraulic pressure, rather than it is directly straight using water flow
Dynamic microswitch is contacted, thus, it shuts down and reacts more accurate, improve the stability of overflow valve, will not be asked because of external water pressure
The case where topic causes microswitch shake accidentally to touch.
Detailed description of the invention
Fig. 1 is that the cross-sectional view under the open state of structure is shut down in the jetting machine overflow valve overflow of the utility model；
Fig. 2 is that the cross-sectional view under the shutdown status of structure is shut down in the jetting machine overflow valve overflow of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As depicted in figs. 1 and 2, structure, including overflow valve sheet are shut down in the jetting machine overflow valve overflow of the utility model
Body 1, and the switching mechanism 2 cooperated with overflow valve body 1；It further include total valve module 3, total valve module 3 includes and overflow valve sheet
The shell 4 that body 1 connects, 4 center of shell is provided with main valve core assembly 5, is arranged between 5 end of main valve core assembly and shell 4
There is reset spring 6；Relief valve spool component 7,7 one end of relief valve spool component and total valve core are provided in overflow valve body 1
The end of component 5 is corresponding, and the other end of relief valve spool component 7 is provided with push-rod assembly 8, and relief valve spool component 7 is along overflow
1 inner wall transverse shifting of valve body, and push-rod assembly 8 is driven to be acted accordingly.When Fig. 1 is that jetting machine works, overflow
Valve state, water flow flow to water outlet from water inlet and carries out normal water outlet work, at this point, the upper end of total valve module 3 and overflow valve
Core assembly 7 is to be detached from.
Push-rod assembly 8 includes push rod fixing end 9, and the mandril 10 across the push rod fixing end 9；Mandril 10 is socketed push rod
Spring 11, switching mechanism 2 include switch housing 12, are provided with microswitch 13, the triggering of microswitch 13 in switch housing 12
One sliding block 14 of end setting, the end of sliding block 14 are corresponding to the end of mandril 10.Push rod spring 11 applies the elastic force of reset, water outlet
State lower push rod 10 and sliding block 14 are discontiguous.
The one end opposite with mandril 10 of sliding block 14 be wedge surface, when offseting convenient for mandril 10 and sliding block 14 can triggered as normal it is micro-
Dynamic switch 13.
The end of main valve core assembly 5 is in boss-shaped, and relief valve spool component 7 is provided with corresponding to the end of the boss-shaped
Inclined surface 16.The end of main valve core assembly 5 also has sealing ring 17, plays sealing function.
Working principle: effluent state does not repeat, because open state is technical solution well known to those skilled in the art.?
When closing rifle shutdown, the water outlet end pressure of total valve module rises, so that reset spring above pushes away total valve core until on total valve module
It holds and offsets below relief valve spool component, and then relief valve spool component also moves up, push push-rod assembly top to sliding block, it is sliding
The traversing triggering microswitch of block, microswitch keep power-off condition, have the function that overflow is shut down.Shutdown status can be found in
Fig. 2
The utility model has the advantages that structure is shut down in the jetting machine overflow valve overflow of the application, overflow is realized using the variation of hydraulic pressure
The movement of valve internal structure, rather than microswitch is directly directly touched using water flow, thus, it shuts down and reacts more accurate, mention
The high stability of overflow valve, the case where microswitch shake will not be caused accidentally to touch because of external water pressure problem.
In conclusion above embodiment is not the restricted embodiment for being the utility model, the technology of all this fields
The modification or equivalent deformation that personnel are carried out on the basis of the substantive content of the utility model, in the skill of the utility model
Art scope.
