Description
Technical field
The utility model relates to a kind of cross valve, specifically refers to a kind of cross valve with filter.
Background technology
Four-way change-over valve is the important devices of heat pump type air conditioner, is applicable to the refrigeration plants such as central authorities, split, window air conditioner.As Fig. 1, cross valve generally comprises main valve 1, pilot valve 2, four adapter and four capillaries, main valve 1 is connected with four adapters: D connection, E adapter, S adapter and C adapter.The D connection other end connects compressor air outlet, and the S adapter other end connects compressor air inlet, and the E adapter other end connects indoor units, the outer unit of C adapter other end junction chamber.Pilot valve 2 comprises pilot slide valve 21, spring 22 and solenoid 23.When no power, pilot slide valve 21 is positioned at the left end of pilot valve 2 under the effect of spring 22, and main valve 1 right-hand member pressure is higher than left end pressure, and spool 11 slides to main valve left end, and cross valve is in kind of refrigeration cycle state.When being energized, pilot slide valve 21 is positioned at the right-hand member of pilot valve 2 under the effect of solenoid 23, and main valve 1 left end pressure is higher than right-hand member pressure, and spool 11 slides to main valve 1 right-hand member, and cross valve is in and heats recurrent state.
The pressure differential that cross valve commutation depends on main valve about 1 two ends drives spool about 11 slippage, and pressure differential is provided by the coolant media of air-conditioning system inside.All be full of coolant media at main valve inner chamber and pilot valve inner chamber, if include impurity in coolant media, then likely the fault that capillary blocks and spool 11 is stuck occur.
Utility model content
The purpose of this utility model is to provide a kind of cross valve with filter, reduces the fault of the blocking of cross valve capillary and spool jam.
The technical scheme realizing the utility model object is: a kind of cross valve, comprises main valve, pilot valve, four capillaries and four adapters; Four capillaries connect main valve and pilot valve, and four adapters are respectively: D connection, E adapter, S adapter and C adapter; One end of four adapters is all communicated with main valve, and the D connection other end connects compressor air outlet, and the S adapter other end connects compressor air inlet, and the E adapter other end connects indoor units, the outer unit of C adapter other end junction chamber; Filter is provided with in the D connection be connected with compressor outlet.
The middle part of described D connection is provided with one section of expansion arc, and the radial dimension of expansion arc is greater than the radial dimension at other positions of D connection, and described filter is positioned at the expansion arc of D connection.
Described filter is a filter net sheet.
Described filter net sheet is semi-spherical shape, and the one side of protrusion is windward side.
The utility model has positive effect: (1) cross valve of the present utility model is provided with filter, prevents the impurity in air-conditioning system coolant media from entering cross valve, decreases the fault rate of the blocking of cross valve capillary and spool jam.
(2) middle part of the D connection of the utility model cross valve is provided with the expansion arc of one section of accommodation filter, the radial dimension of expansion arc is greater than the radial dimension at other positions of D connection, this expansion arc can prevent the continuous accumulated plugging D connection of the impurity at cross valve filter place in Long-Time Service process, reduces the maintenance times of air-conditioning equipment.
(3) filter of the present utility model is a filter net sheet, with low cost.
(4) filter net sheet of the present utility model is semi-spherical shape, and the one side of protrusion is windward side, and first the impurity leached be piled up in the border of D connection expansion arc, and the pipeline not affecting cross valve is unobstructed.
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is cross valve schematic diagram.
Fig. 2 is the cross valve structural representation of band filter.
Label in accompanying drawing is:
Main valve 1, spool 11, pilot valve 2, pilot slide valve 21, spring 22, solenoid 23, filter 3, expansion arc 4.
Detailed description of the invention
(embodiment 1)
See Fig. 2, the present embodiment cross valve, comprise main valve 1, pilot valve 2, four capillary and four adapters, four capillaries are communicated with main valve 1 and pilot valve 2; Four adapters are respectively: D connection, E adapter, S adapter and C adapter; One end of four adapters is all communicated with main valve 1, and the D connection other end connects compressor air outlet, and the S adapter other end connects compressor air inlet, and the E adapter other end connects indoor units, the outer unit of C adapter other end junction chamber.
The middle part of the described D connection be connected with compressor outlet is provided with one section of expansion arc 4, and the radial dimension of expansion arc 4 is greater than the radial dimension at other positions of D connection, and filter 3 is positioned at the expansion arc 4 of D connection.Described filter 3 is the filter net sheet of semi-sphere shape, and the one side of protrusion is windward side.
When air-conditioning equipment is opened, intrasystem coolant media enters cross valve by D connection under the effect of compressor, and the oxide skin in coolant media, foreign material and deteriorated grease filtrating are out deposited in the expansion arc 4 of D connection by the filter net sheet in D connection.The semi-spherical shape of the larger and filter net sheet of the radial dimension due to expansion arc 4, first the impurity being filtered out be piled up in the border of expansion arc 4, do not affect the regular path of D connection.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
