Description
Technical field
The present invention relates to a kind of four-way valve, particularly a kind of idle call four-way valve.
Background technique
The refrigeration of air conditioner heat pump system, switch between heating and accomplish through four-way valve.When in general freezing; See accompanying drawing 1; Traditional four-way valve is through the electromagnetic coil on the power down pilot valve 24; Spring 5 on the pilot valve 2 is in relaxed state, and pilot valve 2 inner height pressure-driven four-way valve valve pieces 13 move to exhaust port 12 and are communicated with condenser port 9, and return-air port 10 is communicated with vaporizer port 11.And when heating, see accompanying drawing 2, the electromagnetic coil 4 of pilot valve 2 must be in "on" position always; Spring 5 on the pilot valve 2 is in contraction state; Pilot valve 2 inner height pressure-driven four-way valve valve pieces 13 move to exhaust port 12 and are communicated with for 11 sections with the vaporizer port, and return-air port 10 is communicated with condenser port 9, power on must for this moment electromagnetic coil 4 always; Make its spring 5 under the electromagnetic force effect, be in contraction state, to accomplish mode switching always.
Among the figure: 1 is pilot valve exhaust connecting tube, and 2 is pilot valve, and 3 is pilot valve valve piece, and 4 is electromagnetic coil; 5 is spring, and 6 is the right balance four-way valve of pilot valve pipe, and 7 is balance four-way valve pipe under the pilot valve, and 8 is the four-way valve shell; 9 is the condenser port, and 10 is the return-air port, and 11 is the vaporizer port; 12 is exhaust port, and 13 is four-way valve valve piece, and 14 is pilot valve left side balance four-way valve pipe.
Chinese patent document number CN 1372089A discloses a kind of bistable four-way selector valve of the switching-over back outage memory of switching on October 2nd, 2002; Have the control valve pocket of boring core through dress in two electromagnetic coils and two and control moving up and down of sliding spool in two valve pockets; The switching effect that reach refrigeration, heats need let one of them electromagnetic coil power at the switching-over initial stage, after commutating successfully; Can make power down process, keep power-failure memory.
This bistable four-way selector valve can solve traditional four-way valve and heat the problem that must always power on; But the time; Because the structure of bistable four-way selector valve is extremely complicated: comprise two electromagnetic coil assemblies, two operating valve block assemblies and four valve pieces etc., and the sealing requirements height between four valve pieces and the valve piece cavity; So have the risk of leaking, also will there be certain risk in the switching-over reliability of this bistable four-way selector valve.In addition; Because the component of bistable four-way selector valve relate to technologies such as welding in working process; And welding procedure causes that easily situations such as the action of slide block is bad take place, so the requirements of making of bistable four-way selector valve is very high, cause its fabricating cost quite high.
Summary of the invention
The object of the invention aim to provide a kind of simple and reasonable, component are few, fabricating cost is low, energy consumption is low, control idle call four-way valve simpler, applied widely, to overcome deficiency of the prior art.
A kind of idle call four-way valve by this purpose design; Comprise the four-way valve valve piece that is arranged in the four-way valve shell; The four-way valve shell is provided with four-way valve exhaust connecting tube, four-way valve vaporizer connecting tube, four-way valve return-air connecting tube and the four-way valve condenser connecting tube that communicates with its inner chamber; Its structure characteristic is that an end of four-way valve valve piece and an end of spring join; The inwall of the other end of this spring and four-way valve shell joins, and the four-way valve shell that is positioned at the spring position is provided with and is used for the flexible electromagnetic coil of control spring.
Said spring comprises left spring and right spring; Electromagnetic coil comprises left electromagnetic coil and right electromagnetic coil; The right ends of four-way valve valve piece is joined with an end of left spring and right spring respectively; The inwall in the left side of the other end of left spring and four-way valve shell joins; The other end of right spring joins with the inwall on the right side of four-way valve shell, is used to control the left side that left electromagnetic coil that left spring stretches is arranged on the four-way valve shell, and the right electromagnetic coil that is used to control right telescopic spring is arranged on the right side of four-way valve shell.
Said idle call four-way valve also comprises left balance tube, and an end of this left side balance tube runs through the inner left wall of four-way valve shell, and the other end of left balance tube was communicated on four-way valve condenser connecting tube.
Said idle call four-way valve also comprises right balance tube, and an end of this right side balance tube runs through the right side inwall of four-way valve shell, and the other end of right balance tube was communicated on four-way valve vaporizer connecting tube.
The present invention can be provided with spring and corresponding electromagnetic coil in the one or both ends of four-way valve valve piece as required, has bigger flexibility and adaptability.
When the right ends at four-way valve valve piece is respectively arranged with left spring and right spring and left electromagnetic coil and right electromagnetic coil; Assurance four-way valve valve piece is switched on respectively at left electromagnetic coil and right electromagnetic coil, and four-way valve valve piece can move left and right under the different elastic force effect of left spring and right spring.Left side balance tube and right balance tube make up pressure reduction by the left and right sides of four-way valve valve piece; Guaranteeing that at left electromagnetic coil or right electromagnetic coil pressure reduction makes up after energising a period of time, but just power down process; And not needing to let electromagnetic coil be in "on" position always, power consumption is low.
When only when an end of four-way valve valve piece is provided with spring and electromagnetic coil, when heating, electromagnetic coil does not have access to electricity; And when refrigeration has just begun; Electromagnetic coil powers on and drives four-way valve valve piece and move to an end, after pressure reduction makes up, but just power down process; And not needing to let electromagnetic coil be in "on" position always, power consumption is low.
The present invention has saved the pilot valve in the background technique; Overcome simultaneously and need let electromagnetic coil be in the drawback of power-up state when heating always; And only need in refrigeration, heat and all lead to once electricly under two kinds of patterns, utilize the left spring that left electromagnetic coil and right electromagnetic coil pair and four-way valve body on the idle call four-way valve join and the control respectively of right spring, and after pressure reduction is set up; Can carry out power down process to the four-way valve coil; Utilize system self pressure reduction to accomplish the hold mode of sliding fast position, thereby let four-way valve be in a steady state, reach more purpose of energy saving.
That the present invention has is simple and reasonable, component are few, fabricating cost is low, energy consumption is low, control is simpler, advantage of wide range of application.
