Abstract
The invention discloses a kind of flow regulators with back flow protection function, including the valve pipe that one end is closed, the valve pipe are internally provided with mandrel；The same side of valve pipe one end is arranged at intervals with first outlet and the first import, the other side of valve pipe one end is correspondingly arranged on the second import and second outlet, and the first outlet and the joining place of the second import are provided with and the matched core axle hole of mandrel head end.The present invention is small, and cost is relatively low, can adjust using flow and easy to operate, improve the comfort of human body.
Description
Technical field
The present invention relates to mini-refrigerator system fields, more specifically to a kind of flow with back flow protection function
Regulating device.
Background technology
Currently, mini-refrigerator system can only persistently export refrigerating capacity, the fluid delivery pump in system at a temperature of setting
Do not have back flow protection function yet.Part user of service feels " colder " when environment changes, and needs to human body requirements
Fluid Volume carries out adjusting appropriate, and common valve can change the output pressure of delivery pump, when serious when adjusting piping flow
Pump " being suppressed dead " can be caused to lead to system-down；In addition the output pressure pumped can also change the fluid of other users of service when changing
Amount, to influence the normal use of other staff.
Invention content
The technical problem to be solved in the present invention is, provides a kind of flow regulator with back flow protection function.
The technical solution adopted by the present invention to solve the technical problems is：Construct a kind of flow with back flow protection function
Regulating device, includes the valve pipe of one end closure, and the valve pipe is internally provided with mandrel；The same side interval of valve pipe one end is set
It is equipped with first outlet and the first import, the other side of valve pipe one end is correspondingly arranged on the second import and second outlet, described
First outlet and the joining place of the second import are provided with and the matched core axle hole of mandrel head end.
In the above scheme, it is provided with sealing ring between the valve inside pipe wall and mandrel.
In the above scheme, the valve pipe other end is circumscribed with adjusting knob, the tail end company of the adjusting knob and mandrel
It connects.
Implementing the present invention has the flow regulator of back flow protection function, has the advantages that：
The present invention has the small of the flow regulator of back flow protection function, and easy to adjust, cost is relatively low, can adjust
Section uses flow, improves the comfort of human body.When being reduced using flow, the not used fluid in part has back through the invention
The flow regulator of stream defencive function directly flows back, and does not influence the normal operation of pump, and protective effect is played to pump and pipeline,
Other users of service will not be had an impact.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples, in attached drawing：
Fig. 1 is the structural schematic diagram for the flow regulator that the present invention has back flow protection function；
Fig. 2 is flow regulator of the present invention with back flow protection function fluid circulation direction schematic diagram when adjusting.
In figure：First import 1, first outlet 2, the second import 3, second outlet 4, core axle hole 5, mandrel 6, adjusting knob 7,
Sealing ring 8, valve pipe 9.
Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control attached drawing is described in detail
The specific implementation mode of the present invention.
As shown in Figs. 1-2, the present invention has the flow regulator of back flow protection function, including the valve pipe 9 that one end is closed.
Valve pipe 9 is internally provided with mandrel 6, and sealing ring 8 is provided between 9 inner wall of valve pipe and mandrel 6.
The same side of 9 one end of valve pipe is arranged at intervals with first outlet 2 and the first import 1, and the other side of 9 one end of valve pipe corresponds to
It is provided with the second import 3 and second outlet 4, first outlet 1 is provided with the joining place of the second import 4 and is matched with 6 head end of mandrel
Core axle hole 5.9 other end of valve pipe is circumscribed with adjusting knob 7, and adjusting knob 7 is connect with the tail end of mandrel 6.
Working principle of the present invention is as follows：The flow regulator with back flow protection function is mounted on the two-tube of conveying
On the road, inlet and outlet corresponding with pipeline are connected respectively for the first import 1, first outlet 2, the second import 3, second outlet 4, refrigeration system
System exports fluid by pump, the first import 1 is reached by the road, into the flow regulator with back flow protection function.
It when human body sensory is comfortable, need not adjust, mandrel 6 is in position as shown in Figure 1, and fluid passes through the first import 1, second at this time
Outlet 4, user of service and the second import 3, first outlet 2, refrigeration system, are recycled.When use environment changes (such as from
Ground is raised to high-altitude, and environment temperature is lower by height), when human body sensory is cool or cold, need to using flow to be adjusted, it is right at this time
Adjusting knob 7 is revolved, mandrel 6 is in position as shown in Figure 2 at this time, opens reflux, and a part of fluid to human body carries out heat exchange, separately
A part of then be passed straight back to first outlet 2 by core axle hole 5, loop direction is as shown in Figure 2.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited in above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make very much
Form, all of these belong to the protection of the present invention.
