Description
Technical field
The utility model is related to refrigerator part manufacturing technology field, specially a kind of freezer compressor shuttle valve.
Background technology
The valve body of shuttle valve has first and second entrance and one outlet.It is internal when compressed air by first entrance enters fashionable
Valve element seals second entrance, and compressed air is flowed to by first entrance and exported.Such as compressed air is entered by second entrance, and valve element will
First entrance is closed, and compressed air is flowed to by two entrances and exported.When compressed air makees reverse flow, such as pneumatic cylinder or flap row
Compressed air is put, due to pressure condition, valve element rests on original position.At present, the valve element of traditional shuttle valve is a circle
Steel ball ball, when gas is in flowing, not only sealed speed is slower when steel ball ball is sealed, and sealing is poor；Sometimes steel ball ball
During positioned at outlet, the whole gas process of circulation has some setbacks, and reduces operating efficiency.The pipeline of traditional compressor shuttle valve with
High temperature and high pressure gas are contacted, and the service life of shuttle valve is short.
Utility model content
The purpose of this utility model is to provide a kind of freezer compressor shuttle valve, it is ensured that suitable when gas circulates in pipeline
When smooth property and choked flow rapidly and efficiently, the service life of valve element is extended.
To achieve these goals, the utility model provides following technical scheme.
A kind of freezer compressor shuttle valve, including valve body and valve element, the valve body include stage casing pipeline and and stage casing
First and second air inlet pipeline of pipeline connection, the caliber of first and second air inlet pipeline is less than the caliber of stage casing pipeline, the valve
Core includes core body and two core prints positioned at core body end face, the wedge shaped shape of core print and in face of airintake direction, and described first and second
Air inlet pipeline is provided with stage with stage casing pipeline intersection.
In above-mentioned technical proposal, the wedge shaped shape of core print and in face of airintake direction, core print can at utmost reduce gas
The flow resistance of body, it is ensured that medium swimmingly can circulate in pipeline.The setting of stage, one side stage supplies core body against limit
Made valve element rollback, prevent core body obstruct pipeline, influence gas normal through；Another aspect core body is close to stage, it is ensured that
Valve element is by one end pipeline excellent sealing.The caliber of first and second air inlet pipeline is less than the caliber of stage casing pipeline, is so easy to
Valve element coordinates with stage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is schematic diagram when the utility model seals the first pipeline；
Fig. 3 is schematic diagram when the utility model seals the second pipeline；
Fig. 4 is the structural representation of the utility model valve element.
Embodiment
It is described in further detail with reference to Fig. 1 to 4 pairs of the utility model.
A kind of freezer compressor shuttle valve, including valve body 10 and valve element 20, the valve body 10 include stage casing pipeline C and
First and second air inlet pipeline A, B being connected with stage casing pipeline C, described first and second air inlet pipeline A, B caliber is less than stage casing pipeline C
Caliber, the valve element 20 include core body 21 and two core prints 22 positioned at the end face of core body 21, the wedge shaped shape of the core print 22 and
In face of airintake direction, described first and second air inlet pipeline A, B and stage casing pipeline C intersections are provided with stage 11.
The wedge shaped shape of the core print 22 and in face of airintake direction, core print 22 can at utmost reduce the flowing resistance of gas
Power, and Large Diameter Pipeline stage casing pipeline C increase gas flowing when pipeline sectional area, it is ensured that medium can be swimmingly in pipeline
Middle circulation.Described first and second air inlet pipeline A, B and stage casing pipeline C intersections are provided with stage 11, and one side stage 11 supplies core body
21 retract against valve element 20 is limited, and prevent that core body 21 from obstructing pipeline, influence gas normal through, another aspect core body 21 with
Stage 11 is close to, it is ensured that valve element 20 is by one end pipeline excellent sealing.During described first and second air inlet pipeline A, B caliber are less than
Duan Guanlu C caliber, is easy to valve element 20 to coordinate with stage 11.
The core body 21 is cylindrical and periphery wall on be provided with the edge of ball 231 set on wing plate 23, the wing plate 23
The groove set on the pipeline C of stage casing on the flute length direction movement of groove, the stage casing pipeline C is constituted with valve element 20 to be circumferentially rotated, axially
It is mobile to coordinate.
The groove set on the pipeline C of stage casing coordinates with wing plate 23, and the setting of wing plate 23 ensures valve element 20 all the time in fixation
On motion path, prevent valve element 20 from being rotated in the presence of cyclone, influence the air-tightness of shuttle valve.The ball set on wing plate 23
231 coordinate with the groove on pipeline C, reduce the resistance of groove on wing plate 23 and pipeline C, it is ensured that valve element 20 is when sealing one end pipeline
It is efficient quick.
Fluorubber is provided with the lozenges of the core print 22.During prolonged use, due to core print 22 and pipe
Frequently, the contact position on the end face of core print 22 with stage on pipeline 11 is most easy to wear for the ends contact of road 30, is set on the end face of core body 21
Fluorubber 24 and the ends contact of pipeline 30, not only reduce the consumption of fluorubber 24, reduce manufacturing cost, and fluorubber 24 has
Standby high temperature resistant, ageing-resistant and excellent mechanical performance, had both ensured the sealing of one end pipeline, making for valve element 20 are substantially prolongs again
Use the life-span.
Fluorubber is provided with described first and second air inlet pipeline A, B and stage casing pipeline C inner tubal wall, pipe is greatly strengthen
The decay resistance on road, extends the service life of pipeline.
Illustrate the motion process of valve element with reference to Fig. 1 to 3, when the first pipeline A of shuttle valve is in air-suction state, valve
Core 20 is moved to the second pipeline B direction, when core body 21 is contacted with stage 11, and valve element 20 stops mobile and seals the second pipeline B；
Similarly, when the second pipeline B is in air-suction state, valve element 20 is moved to the first pipeline A direction, and core body 21 is contacted with stage 11
When, valve element 20 stops mobile and seals the first pipeline B.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.And these belong to the obvious changes or variations that connotation of the present utility model extends out and still fall within this practicality
New protection domain.
