Abstract
An axial flow type refrigerating circuit check valve comprises a valve body (12), a valve core (13), a spring (14) and a flow guide cover (15) and is characterized in that the valve body (12) partitions a refrigerating circuit into two accommodation cavities, the flow guide cover (15) provided with air outlets (19) is connected with the valve body (12) which is provided with an air inlet (11), the spring (14) sleeves the valve core (13), and a conical end of the valve core (13) is abutted against the conical inner end face of the air inlet (11) under the action of the spring (14), so that sealing is realized, and backflow of refrigerant in the refrigerating circuit when the pressure in the accommodation cavity at one end of the air inlet (11) is smaller than the sum of the pressure of the spring and the pressure of the accommodation cavity at the other end of the air inlet (11) can be prevented. The axial flow type refrigerating circuit check valve has the advantages of simple structure, capability of adaptive adjustment of the pressure of each air outlet, and evident reduction of noise and vibration.
Description
Technical field
The present invention relates to a kind of refrigeration technology, the one-way valve using in especially a kind of oblique tray type compressor, specifically a kind of axial flow dynamic formula refrigerating circuit one-way valve.
Background technique
Conventionally, compressor air-flow between air-breathing and exhaust conversion can produce pulsation, causes refrigeration system to produce noise.In refrigeration system, the sectional area difference of each circulation duct, the volume of each air storing cavity is also not quite similar simultaneously, and gas or liquid all can produce pulsation in the time flowing into and flow out these positions, produce noise, are accompanied by vibration.These noises and vibration can affect the travelling comfort that frame is taken advantage of, and cause user's complaint.For this reason, conventionally need to install additional in loop one-way valve, but because current one-way valve is mostly radially exhaust, this will need to change pipeline trend, cause pipeline complexity, inconvenience is installed, the one-way valve that therefore designs a kind of axial exhaust is the key that solves compressor operating balance.
Summary of the invention
The problem that the object of the invention is to affect for easily producing exhaust noise and vibration in existing compressor operation the travelling comfort that frame takes advantage of, designs a kind of vibration and the little axial flow dynamic formula refrigerating circuit one-way valve of noise.
Technological scheme of the present invention is:
A kind of axial flow dynamic formula refrigerating circuit one-way valve, comprise valve body 12, spool 13, spring 14 and air guide sleeve 15, it is characterized in that refrigerating circuit is divided into two cavity volumes by described valve body 12, air guide sleeve 15 is connected with valve body 12, valve body 12 is provided with suction port 11, air guide sleeve 15 is provided with air outlet 19, spring 14 is sleeved on spool 13, the tapered end of spool 13 offsets with the taper interior edge face of suction port 11 under the effect of spring 14, to play seal action, while preventing that pressure in the cavity volume of suction port 11 one end is less than the pressure of the other end cavity volume and spring pressure sum, refrigeration agent in refrigerating circuit flows backwards.
Described air outlet 19 is made up of jointly axially open on air guide sleeve 15 and refrigerating circuit tube wall.
Described valve body 12 and spool 13 are realized and being rotatably connected by a concavo-convex coupled structure 20, to ensure the dynamic balancing of each air outlet 19, reduce flow perturbation and noise.
Beneficial effect of the present invention:
The present invention, by being contained in the one-way valve of compressor inside, controls air-flow and flows to low voltage terminal from high voltage terminal.In mobile process, because the variation of aperture and volume causes the variation of pressure, produce vibration and noise.Air-flow by one-way valve must reach certain pressure on the one hand could close and the air-flow by valve port is carried out to damping by valve port and when the pressure surge, makes air-flow steady; Can enough allow again on the other hand air-flow change direction, make air-flow more steady.
One-way valve of the present invention has simple in structure, and energy self adaption is adjusted the pressure of each air outlet, obviously reduces noise and vibration.

Fig. 1 is sectional structure schematic diagram of the present invention.
Fig. 2 is the air-flow schematic diagram of one-way valve of the present invention.
Fig. 3 is form structure schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As Figure 1-3.
A kind of axial flow dynamic formula refrigerating circuit one-way valve, comprise valve body 12, spool 13, spring 14 and air guide sleeve 15, as shown in Figure 1, refrigerating circuit is divided into two cavity volumes by described valve body 12, air guide sleeve 15 and valve body 12 are realized and being rotatably connected by a concavo-convex coupled structure 20, to ensure the dynamic balancing of each air outlet 19, reduce flow perturbation and noise, valve body 12 is provided with suction port 11, air guide sleeve 15 is provided with air outlet 19, air outlet 19 is made up of jointly axially open on air guide sleeve 15 and refrigerating circuit tube wall, as shown in Figure 3, spring 14 is sleeved on spool 13, the tapered end of spool 13 offsets with the taper interior edge face of suction port 11 under the effect of spring 14, to play seal action, while preventing that pressure in the cavity volume of suction port 11 one end is less than the pressure of the other end cavity volume and spring pressure sum, refrigeration agent in refrigerating circuit flows backwards.
As shown in Figure 1, under free state, only have T1 end pressure to be less than or equal to making a concerted effort of T2 end pressure and spring force, in the time that T1 end pressure is greater than this and makes a concerted effort, will push valve port open, will again close or reduce as T1 end pressure is less than the valve port of making a concerted effort, maintain a transient equiliblium.Now will ensure whenever gas all can not flow to TI end from T2 end.Simultaneously the flow direction of air-flow as shown in Figure 2, is pushed valve port 16 open from T1 end 17 and is flowed to vertically T2 end 18 through air guide sleeves, through the water conservancy diversion of air guide sleeve, gas smoothness from axial outflow and can not reverse flow, ensured air-flow steadily, one-way flow.As shown in Figure 3, the necessary condition of valve work is that two ends T1 and the T2 end of valve port forms cavity volume separately, and cavity volume is blocked completely by valve.Therefore, this kind of valve must be assemblied on the air suction way and exhaust passageway of compressor, utilizes this valve to block gas circuit, allows the air-flow can only one-way flow.
Certainly, example of the present invention is to be assemblied on compressor, but is not limited to be assemblied on compressor, also can be assemblied in other positions of air-conditioning system, and under the prerequisite not departing from the scope of the present invention, those of skill in the art can modify and improve.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
