Abstract
Four-way-two-way electromagnetic inverting valve slide block parts relate to the cooling technique. The deficiency that the resistance of a gliding block is big and the engaging relation with the big-bowl valve bottom is not good exists in the current technique. The utility model comprises a gliding block body, the bottom of the gliding body forms a first sealing face, a communicating cavity is arranged from the bottom of the body to the inner portion of the body, and one side of the communicating cavity on the body extends a swallowtail portion. The utility model is characterized in that the swallowtail portion is provided with a second sealing face which is on the same plane with the bottom of the body and a blind hole is arranged from the second sealing face to the inner portion of the swallowtail, the blind hole is used for reducing the bottom area of the swallowtail portion, thereby the friction force is reduced when the gliding block is moving.
Description
Technical field
The utility model relates to refrigeration technology, and the solenoid valve that is used for compressor, air-conditioning, refrigerating machine, water heater control gaseous or flow direction specifically is the slider part of four-way change-over valve especially.
Background technique
Now need a kind of four-way valve, a kind of mode of operation is a four-way, and a kind of mode of operation is two logical, can switch between logical at four-way, two, to be applicable to the air-conditioning variable conpacitance compressor.Because design and process aspect, the concrete structure of the slider part of this valve is typing never.ZL200520043958.5 number Chinese utility model patent specification discloses the technological scheme of a kind of " four-way-two energising magnetic selector valve ", it be by " jorum valve (32) one sides are provided with one can be on a position; and the valve bowl tongue (32a) of the 3rd passage that only in blocking-up jorum valve seat (30) on this position, be not covered " technical measures to reach a kind of mode of operation be four-way, another kind of mode of operation is two logical technical purposes.Yet this jorum valve (32) that is provided with valve bowl tongue (32a) structure only is a kind of initial imagination, remains in actual applications in some defectives to cause its technological scheme to be difficult to carry out:
The bottom surface of valve bowl tongue (32a) is a continuous plane, when it slides on jorum valve seat (30) with jorum valve (32), bigger with the area of contact of jorum valve seat (30), except meeting increases slip resistance, also, it has increased difficulty for reaching sealing effect.
Valve bowl tongue (32a) is " cantilever " shape as the structure that extends out from jorum valve (32) one sides, therefore easily produces distortion in its working procedure and destroys the relation of being sealed and matched between itself and the jorum valve seat (30).
In use indeformable in order to guarantee jorum valve (32), so process with metal construction more than the jorum valve (32) of prior art, the difficulty of sealing between jorum valve (32) and the jorum valve seat (30) increased thus again.
The model utility content
The technical assignment of the technical problems to be solved in the utility model and proposition be overcome the slip resistance that the jorum valve of prior art exists big, with the not good defective of jorum valve base sealing matching relationship, a kind of four-way-two energising magnetic selector valve slider part is provided.For this reason, the utility model is by the following technical solutions:
Four-way-two energising magnetic selector valve slider part, comprise a slide block body, the bottom surface of this body forms primary sealing area, bottom surface from body is provided with communicated cavity to body interior, a side of communicated cavity is extended dovetail portion on body, it is characterized in that the bottom surface that described dovetail portion has with body is positioned at conplane secondary sealing area, and to dovetail portion inside blind hole is set from secondary sealing area.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described primary sealing area and secondary sealing area are provided with continuously.
The cross section of described communicated cavity is a U-shaped.
The position of the corresponding blind hole of described dovetail portion is provided with stiffening rib.
Be supported with support stick in the described communicated cavity.
Described slide block body and dovetail portion are by making with the injection moulding of PPS material, and described support stick is that two ends are that conical intermediate section is columniform stainless steel bar.
The beneficial effects of the utility model are:
Be positioned at conplane secondary sealing area by the bottom surface that is provided with in described dovetail portion with body, and to dovetail portion inside blind hole be set, be used for reducing the basal area of dovetail portion from secondary sealing area, thus the frictional force when reducing slide block movement; In addition, stiffening rib the intensity that has improved dovetail portion is set, guarantee that it is indeformable under certain pressure, eliminated " cantilever " state; And the support stick that supports in the communicated cavity has been realized the change of slide block manufactured materials guaranteeing the sealing between slide block and the valve seat thus, and guarantees that by support stick slide block is indeformable; The cross section of described communicated cavity is a U-shaped, and chamber is the arc roof construction, and inner wall smooth effectively reduces flow resistance.
Description of drawings
Fig. 1 is the schematic bottom view (worm's eye view) of the utility model slider part.
Fig. 2 is that the K-K of Fig. 1 is to sectional view.
The tool present embodiment
As shown in Figure 1, this slider part is made of slide block body, dovetail portion and a support stick:
Body 1 is made integral structure with the 2 usefulness PPS material injection mouldings of dovetail portion, the bottom surface of this body 1 forms primary sealing area 4, bottom surface from body 1 is provided with communicated cavity 5 to body interior, dovetail portion 2 extends in a side of communicated cavity 5 on the body 1, and the bottom surface that dovetail portion 2 has with body 1 is positioned at conplane secondary sealing area 6, and to dovetail portion 2 inside blind hole 7 is set from secondary sealing area 6.
More specifically, primary sealing area 4 is provided with continuously with secondary sealing area 6, thereby guarantees that the slider part volume is little.
The cross section of communicated cavity 5 is a U-shaped, and the U die cavity is a smooth indent runner, in order to realizing the connection between two or more runners, and with runner in the U die cavity and the outer runner blocking-up of U die cavity, forms the chamber of two relative closures.The U die cavity is outside for cooperating driving parts, is designed to step-like; Inside is " U " shape that Open Side Down, and chamber is the arc roof construction, and inner wall smooth effectively reduces flow resistance.
Support stick 3 is supported in the communicated cavity 5; Support stick 3 is that two ends are that conical intermediate section is columniform stainless steel bar.
