Description
Technical field
The present invention relates to air-conditioning technical fields, specifically, being to be related to a kind of idle call four-way valve.
Background technique
Four-way valve is indispensable component in air conditioner, can be with by the switching to four port on-off of four-way valve
Realize the switching of the refrigeration and heating circulation of air conditioner.
Idle call four-way valve arrangement in the prior art is as shown in Figure 1, include main valve body (01), formation in main valve body (01)
Have valve chamber (02), four connecting tubes being connected to valve chamber (02) are offered on main valve body (01), is respectively as follows: the D being located above and connects
It takes over (03), is located below the E connecting tube (04), S connecting tube (05) and C connecting tube (06) being arranged successively, is set in valve chamber (02)
Having sliding block (07), sliding block (07) has the cavity (08) of opening downward, and sliding block (07) can be slided along valve chamber (02) inner wall, and
Sliding block (07) and valve chamber (02) inner wall keep sealing.In general, the compressor outlet of D connecting tube (03) and air conditioner of four-way valve
Connection, C connecting tube (06) are connected to the outdoor heat exchanger of air conditioner, and S connecting tube (05) is connected to the compressor inlet of air conditioner,
E connecting tube (04) is connected to the indoor heat exchanger of air conditioner.The working principle of four-way valve are as follows: when four-way valve no power, sliding block
(07) it is located at first position (such as Fig. 1 a), D connecting tube (03) is connected with C connecting tube (06), E connecting tube (04) and S connecting tube
(05) it is connected, realizes to indoor refrigeration；When four-way valve is powered, sliding block (07) is slid into the third place (such as Fig. 1 c), and D connects
Adapter tube (03) is connected with E connecting tube (04), and C connecting tube (06) is connected with S connecting tube (05), realizes to indoor heating.
The primary condition of four-way valve commutation is the pressure difference (F at piston (09) both ends1-F2) it is greater than frictional resistance f；When left and right
When the pressure difference of plunger shaft is greater than frictional resistance f, four-way valve commutation starts, still, when sliding block (07) moves to middle position
(such as Fig. 1 b), (06) three adapter tube mutual conduction of E connecting tube (04), S connecting tube (05), C connecting tube of four-way valve, compressor are high
The refrigerant being discharged in pressure pipe directly can flow to S connecting tube through E connecting tube (04), C connecting tube (06) from four-way valve D connecting tube (03)
(05) (compressor return air mouth), causes pressure difference quickly to reduce, and the capacity of compressor is less than four-way valve under the instantaneous state
Intermediate flow, minimum movements pressure difference needed for commutation is not achieved in the pressure difference at four-way valve piston both ends, i.e. F1-F2< f, at this time
Four-way valve cannot continue to commutate and be parked in middle position, and formation is collaborated.It collaborates relatively to be also easy to produce during forming rear operation of air conditioner and make an uproar
Sound, and collaborate and easily cause four-way valve commutation bad, it is unfavorable for the stabilization of air-conditioning system overall performance.Meanwhile existing four-way valve changes

Valve.For the generation for avoiding this phenomenon, the present invention is provided with pressure release component (40).
Preferably, pressure release component (40) includes pressure release valve block (41), valve guard (42), fixed device
(43)；Pressure release valve block (41) is mounted on other fluid channel (202) side of relief hole (203), and tight note sliding block (20) blocks relief hole
(203), pressure release valve block (41) one end is fixed on the other valve seat i.e. sliding block (20) of relief hole (203), and one end is free；Valve block
Lift limiter (42) is on the outside of pressure release valve block (41), and one end is pressed pressure release valve block (41), the other end and pressure release valve block (41) phase
Every 3 to 5 millimeters of distances；Relief hole (203) side is arranged on sliding block (20) in fixed device (43), by pressure release valve block (41) and valve block
The tight note end of lift limiter (42) is fixed on sliding block (20).
Preferably, pressure release valve block (41) is leaf valve, material is elastic stalloy；It is solid that fixed device (43) can be bolt
Determine, rivet is fixed or other fixed forms.
When four-way valve works normally, as shown in Figure 6, pressure release component (40) will not be acted, and pressure release valve block (41) has in itself
Certain elasticity, tight note valve seat, that is, sliding block (20), blocks relief hole (203), by down space, that is, separate cavities (201) on sliding block (20)
Separate with fluid channel (202).It, as shown in Figure 4, may be by but when sliding block (20) is located at the second position middle position Shi Ji
Lead to increased pressure in separate cavities (201) in certain cause specifics, when pressure release valve block (41) pressure at both sides difference is big to a certain extent
When more than valve block elasticity, for valve block under the action of high pressure gas physical strength, free end pushed away from valve seat i.e. sliding block (20), is tightly posted on valve block
On lift limiter (42), gas, by entering fluid channel (202), high pressure is released, to avoid damaging from valve block sideshake
Sliding block (20) and four-way valve, as shown in Figure 7.When pressure release valve block (41) pressure at both sides difference disappears, work of the valve block in elastic force itself
Under, closed position is returned to, four-way valve works normally.
Preferably, be provided on the main valve body (10) be connected to first valve chamber (15) first opening and with institute
State second opening of the second valve chamber (16) connection.
As can be seen from the above description, the above embodiments of the present invention realized the following chievements: working as four-way valve
When sliding block (20) is in an intermediate position when commutation, (14) three root canal road phase of E connecting tube (12) and S connecting tube (13) and C connecting tube
Connection, but D connecting tube (11) are blocked and are allowed to not be connected to tri- connecting tubes of ESC by sliding block (20) and separate cavities (201), Bu Huicun
In the situation that tetra- root canal of ESCD is interconnected, so as to avoid the appearance for phenomenon of collaborating.At this time since D connecting tube (11) is blocked
Or other reasons may be such that the pressure in valve chamber steeply rises, then pressure release component (40) works, at pressure release valve block (41) opening
It in vent position, carries out stablizing pressure release, prevents pressure superelevation in four-way valve and damage sliding block (20) and four-way valve.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention, all in the present invention
In design spirit and principle, any modification, equivalent substitution, improvement and etc. done to technical solution of the present invention should be included in this
In the protection scope of invention.
