Description
Technical field
The utility model belongs to a kind of solenoid valve, relates in particular to a kind of solenoid valve that two-way circulates.
Technical background
In many applications, need on two-way, there be fluid to flow on the circulation duct, simultaneously, under certain situation, need to make runner to end.For example, in the refrigeration system of freezing and heating two states need be arranged simultaneously, just need allow the refrigeration agent two-way flow on the pipeline in refrigeration system, simultaneously, on two flow directions, all should end.In the prior art,, usually adopt as shown in Figure 1 two expansion valves and double check valve, or employing four one-way valves and the structural design of the complexity of an expansion valve as shown in Figure 2 realizes the switching of freezing or heating for heat pump.These two kinds of structures all make the parts of system increase, and cost rises, and because such structure increases the welding part of refrigeration system, the possibility of system leak increases.
Along with the development of technology, adopt the more simple system that two-way circulates just becoming new technological development direction.Be illustrated in figure 3 as the solenoid valve that two-way circulates 2 that on the pipeline of refrigeration system, is arranged on expansion valve 1 next door.It is by resisting the pressure of fluid and do not make freezing medium leakage under the effect of elastic component with the armature attached seal when the needs refrigeration system is ended.The solenoid valve of this structure for be suitable in refrigeration, guaranteeing by the time do not leak, the elastic component of larger volume is set, this just makes the structure of solenoid valve very big.In addition, the structure of existing this class solenoid valve is more complicated all, simultaneously, needs to cooperate high-precision processing, so its price is also high.
Summary of the invention
The purpose of this utility model is to improve the deficiencies in the prior art, and providing a kind of can be communicated with on two-way, can guarantee not leak and the small and exquisite solenoid valve that two-way circulates simple in structure when requiring to end simultaneously on any one two-way direction.
For achieving the above object, the utility model is taked following design proposal:
The solenoid valve that two-way circulates that the utility model relates to, it comprises valve body, valve gap, armature sleeve, armature and coil, described valve gap is fixedly arranged on and makes valve inner have a valve pocket on the described valve body; On described valve body, be provided with liquid entering hole and liquid outlet, on the valve body between described liquid entering hole and the liquid outlet, be provided with the reversible passage that is connected respectively with described liquid in-out mouth, on the termination of described reversible passage, respectively be provided with a through flow hole, in the valve pocket that described valve body forms, also be provided with the common cavity that described two through flow holes are communicated with, on described valve gap that is provided with above the described common cavity of described valve body or valve body wall, establish the hole, be provided with two armature sleeves in the hole, be provided with described coil in the outside of described armature sleeve, described two armature sleeves can be made one, and the armature sleeve also can be structure as a whole with valve gap; The nozzle of described armature sleeve is corresponding with described through flow hole, in described armature sleeve, be provided with the armature that can in described armature sleeve, move, between the barrel of described armature sleeve and armature, be provided with elastic component, external part at described armature is provided with Sealing, be switched on or switched off power supply and make described armature leave and fall within on the through flow hole, being provided with between described armature and armature sleeve can be with the guiding gutter of liquid by adjacent with described through flow hole one side directed opposite side to armature of armature.
The solenoid valve that two-way circulates that the utility model provides is work like this:
When described coil was connected electricity, armature was moved by acting in the armature sleeve of electric current in the coil, and the Sealing on it leaves described through flow hole, and this solenoid valve is opened.When this solenoid valve was in the refrigeration system of refrigerating state, refrigeration agent was entered by the liquid entering hole of valve body, by the runner that is communicated with it, arrive the through flow hole of this side, arrive described common cavity again, enter another through flow hole and runner then, discharge valve body from described liquid outlet at last.When the refrigeration system passage is ended, coil blackout, two armature are all fallen on each self-corresponding through flow hole, but, refrigeration agent in the refrigeration system has certain pressure, enter valve body by liquid entering hole, and revolt described elastic component and make the Sealing on the armature of this side leave through flow hole, refrigeration agent is come common cavity, owing between armature sleeve and armature, be provided with described guiding gutter, part of refrigerant is just come the opposite side of armature in the armature sleeve by guiding gutter, this just makes the both sides of this armature have a pressure reduction, and this pressure reduction makes the Sealing on the armature termination more compress its corresponding through flow hole, and refrigeration agent just can not flow to liquid outlet by through flow hole, so, this solenoid valve is ended reliably.When heating, its working procedure is with above-mentioned opposite.
For guarantee refrigeration and when heating refrigeration system all under same operating mode, move, the difference because of the structure of the runner of the both direction of this solenoid valve does not make its operating mode difference, described double flow channel is the equal symmetry of its shape, size and structure preferably.Described double flow channel is when inlet outlet pressure differential (being the forward working state) and exit port pressure reduction (being the reverse operation state) are identical, and its shape, size and structure be symmetry all; And described double flow channel when inlet outlet pressure differential and exit port pressure reduction are inequality its shape, size can be different with structure, also can make under positive and negative two kinds of working staties residing operating mode identical.
Described through flow hole can be vertical with double flow channel, can make compact structure like this.
If two armature sleeves are made integral piece, can make elliptical shape in cross-section, and the described coil that is sheathed on outside it also is the ellipse that is complementary.
The solenoid valve that two-way circulates that the utility model provides is by being provided with reversible passage in valve body, the so simple structure of armature that through flow hole and common cavity and the armature sleeve that has guiding gutter that is complementary and being used to seals through flow hole has realized and can be communicated with on two-way, on any one two-way direction, require simultaneously by the time can guarantee the purpose of design of not ending with leaking, because the pressure reduction of the opposite side that refrigeration agent is come armature by guiding gutter when ending by these armature both sides compresses the through flow hole of correspondence and seals up, so, do not need the large scale elastic component to resist the pressure of refrigeration agent, therefore, this solenoid valve is not only simple in structure, reliable performance, simultaneously on volume, can do finely, the utmost point is suitable for being used in the two-way system cooling system in the bypass defrost system, or is used as the feed flow stop valve in the two-way system cooling system.
