Description
Technical field
The utility model 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 purpose of this utility model is the problem that affects the travelling comfort that frame takes advantage of for easily producing exhaust noise and vibration in existing compressor operation, designs a kind of vibration and the little axial flow dynamic formula refrigerating circuit one-way valve of noise.
The technical solution of the utility model 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.
The beneficial effects of the utility model:
The utility model, by being contained in the one-way valve of compressor inside, is controlled air-flow and is flowed 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 utility model has simple in structure, and energy self adaption is adjusted the pressure of each air outlet, obviously reduces noise and vibration.
Brief description of the drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
Fig. 2 is the air-flow schematic diagram of one-way valve of the present utility model.
Fig. 3 is form structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
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 described in the utility model 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, do not departing under the prerequisite of scope of the present utility model, those of skill in the art can modify and improve.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
