Description
Technical field:
The utility model relates to valve technology field, relates in particular to a kind of refrigerant system and turns to three-way valve.
Background technique:
Three-way solenoid valve, four-way valve are a kind of flow directions that heat pump type air conditioner changes refrigerated medium that is used for, to realize the product that is converted to purpose of refrigeration mode and heating mode.It mainly is made up of electromagnetic coil, pilot valve, main valve three parts.Electromagnetic coil is contained on the pilot valve, energising by electromagnetic coil and outage realize the commutation to pilot valve, realize the commutation of main valve by the commutation of pilot valve, and by the switching of main valve to pipeline, realize the change of refrigerant flow direction, thus the purpose of the dual-use that makes air-conditioning realize freezing summer to heat winter.But solenoid valve is because of the electromagnetic attraction deficiency, and valve promotes dumb, not first-class phenomenon often occurs fitting badly, closing, turns to reliability low, influences the operation of system; And when using under high-temperature gas refrigerant state, as long-term use or frequently turn to, damage ratio is very high.
The model utility content:
The purpose of this utility model is exactly the deficiency that exists at prior art and provide a kind of and four-way valve is changed system into three-way valve, valve promote smooth and easy flexibly, the reliable refrigerant of steering safety system and turn to three-way valve.
To achieve these goals, the technical solution adopted in the utility model is:
The refrigerant system turns to three-way valve, it includes pilot valve, main valve and electromagnetic coil, main valve inside is provided with piston, the main valve upper end is connected with G interface, the main valve lower end is connected with H interface arranged side by side, K interface, I interface in turn, electromagnetic coil is connected on the pilot valve, and the lower end of pilot valve is communicated with the K interface plug for seal of main valve respectively by E capillary tube, C capillary tube with the piston cavity of the main valve left and right sides.
Described K interface is by the capping plug for seal.
The upper end of described pilot valve connects the compressor air-discharging end by the D capillary tube, and the lower end of pilot valve connects the compressor air suction end by the S capillary tube, and the S capillary tube is between E capillary tube and C capillary tube.
Described pilot valve inside is provided with pressure spring.
The utility model beneficial effect is: the utility model includes pilot valve, main valve and electromagnetic coil, main valve inside is provided with piston, the main valve upper end is connected with G interface, the main valve lower end is connected with H interface arranged side by side, K interface, I interface in turn, electromagnetic coil is connected on the pilot valve, the lower end of pilot valve is communicated with the piston cavity of the main valve left and right sides respectively by E capillary tube, C capillary tube, the K interface plug for seal of main valve, the utility model is transformed into the refrigerant system with the refrigerant four-way valve of maturation and turns to three-way valve, has the following advantages:
1, relies on the pressure difference of refrigerant, promote smooth and easy, safe and reliable flexibly the turning to of valve, do not influence the operation of system; Unfavorable phenomenons such as big electromagnetic attraction, back pressure deficiency can not appear;
2, do not need as four-way valve, connect four pipes, only need connect three pipes, save material, easy for installation;
3, only flow to can be from the interface of main valve upper end toward two interfaces in lower end any interface flow, with this mode that high back pressure is arranged, the sealing force of increase valve, the system that more can guarantee can gas blowby;
4, fill with the four way valve after this improvement and do three-way magnetic valve, not only can be used on the gaseous coolant pipeline of high temperature, also can be used on the liquid refrigerants pipeline of high temperature.
Description of drawings:
Fig. 1 is the structural representation of the utility model "on" position;
Fig. 2 is the structural representation of the utility model off-position.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1～2, the refrigerant system turns to three-way valve, it includes pilot valve 1, main valve 2 and electromagnetic coil 3, main valve 2 inside are provided with piston 21, main valve 2 upper ends are connected with G interface, main valve 2 lower ends are connected with H interface arranged side by side, K interface, I interface in turn, electromagnetic coil 3 is connected on the pilot valve 1, the lower end of pilot valve 1 is communicated with the piston cavity of main valve 2 left and right sides respectively by E capillary tube, C capillary tube, and the K interface of main valve 2 is by capping 4 plugs for seal.
The upper end of pilot valve 1 connects the compressor air-discharging end by the D capillary tube, and the lower end of pilot valve 1 connects the compressor air suction end by the S capillary tube, and the S capillary tube is between E capillary tube and C capillary tube.Pilot valve 1 inside is provided with pressure spring 5.
Working principle of the present utility model is:
When electromagnetic coil 3 is in "on" position, pilot valve 1 overcomes the tension force of pressure spring 5 and moves to right under the magnetic force that electromagnetic coil 3 produces, and pressurized gas enter the left hand piston chamber by the E capillary tube.On the other hand, the gas in right hand piston chamber is discharged, because there is pressure reduction in piston 21 two ends, piston 21 and main valve 2 move to right, and G interface, H interface are communicated.
When electromagnetic coil 3 is in off-position, pilot valve 1 moves to left under pressure spring 5 drives, and pressurized gas enter the right hand piston chamber by the C capillary tube.On the other hand, the gas in left hand piston chamber is discharged, because there is pressure reduction in piston 21 two ends, piston 21 and main slide valve move to left, and G interface, I interface are communicated.
The utility model is transformed into the refrigerant system with the refrigerant four-way valve of maturation and turns to three-way valve, relies on the pressure difference of refrigerant, promotes smooth and easy, safe and reliable flexibly the turning to of valve, does not influence the operation of system; Unfavorable phenomenons such as big electromagnetic attraction, back pressure deficiency can not appear; Do not need as four-way valve, connect four pipes, only need connect three pipes, save material, easy for installation; Only flow to can be from the interface of main valve 2 upper ends toward two interfaces in lower end any interface flow, with this mode that high back pressure is arranged, the sealing force of increase valve, the system that more can guarantee can gas blowby; Fill with the four way valve after this improvement and to do three-way magnetic valve, not only can be used on the gaseous coolant pipeline of high temperature, also can be used on the liquid refrigerants pipeline of high temperature.
