Description
Technical field
A kind of four-way valve is the utility model is related to, more particularly to a kind of four-way valve with filter effect.
Background technology
Four-way valve, hydraulic valve term, it is the control valve with four hydraulic fluid ports, four-way valve is indispensable in refrigeration plant
Part, its operation principle are that, when electromagnetic valve coil is in off-position, pilot slide valve moves to left under the driving of right side compression spring,
Gases at high pressure enter right-hand member plunger shaft after entering capillary, on the other hand, the gas discharge of left end plunger shaft, due to piston both ends
Pressure difference be present, piston and main slide valve move to left, and blast pipe is taken over outdoor unit and communicate, and another two piece-root graftings pipe communicates, and form refrigeration and follow
Ring, when electromagnetic valve coil is in "on" position, pilot slide valve overcomes compression spring under magneticaction caused by magnet coil
Tension force and move to right, gases at high pressure enter left end plunger shaft after entering capillary, and on the other hand, the gas of right-hand member plunger shaft is discharged,
Because piston both ends have pressure difference, piston and main slide valve move to right, and blast pipe is taken over indoor set and communicate, another two piece-root graftings pipe phase
It is logical, form heating circulation, by valve arrangement it is seen that, when main slide valve state in an intermediate position, as shown below, e, s, c
Three adapters mutually ventilation, produces middle flow, now, the refrigerant in compressor inner high voltage pipe can directly flow back to low-voltage tube.
The purpose of flow is when main slide valve is in centre position among design, can play a part of release, system is crushed from height
It is bad.But many four-way valves cause four-way valve to use because external cause causes pilot pipe deformed damaged, or because
Debris enters in four-way valve and causes to block, or causes inner body to become cause thermal damage because main valve temperature is too high.Therefore, we carry
Go out a kind of four-way valve with filter effect.

Compared with prior art, the utility model has the advantages that：
1. the utility model is by setting filter layer and active carbon layer, can by debris and the effective filtration, purification of gas,
Reach the effect of filtering and purification air, can effectively avoid the debris in air is excessive from entering in four-way valve, cause four
Port valve, which blocks, causes four-way valve to damage, and improves the service life of four-way valve, and can effectively by the peculiar smell in gas or
Person's toxic substance purifies, and enhances the degree with fresh air when equipment uses, and improves security when equipment uses.
2. the utility model reaches the reinforcement effect to No.1 pilot pipe and No. two pilot pipes, energy by setting back-up coat
There is effective avoid because pilot pipe deformation caused by extraneous factor, causes four-way valve not work normally, have influence on equipment
Normal operation, enhance the firmness degree of pilot pipe, improve the life-span that equipment uses, and back-up coat gather around it is good heat-resisting
The effect of insulation, there can be the effective working strength for improving equipment, improve the power of work.
3. the utility model has the function that radiating, by absorbing the heat on main valve surface, by heat by setting heat dissipating layer
It is vaporized after amount conversion, can effectively avoids, because overheat causes the part inside main valve to soften, causing four-way valve not work,
The operation of integral device is influenceed, avoids damaging, improves usage time, and can effectively strengthen the firmness degree of main valve,
Strengthen corrosion resistance and prevent the situation of aging from occurring.
