Gas nozzle structure on field is through-type, when the big air-flow of pressure in gas circuit passes through valve, direct collision equipment, causes air to be disturbed
Move and form bigger noise.
Utility model content
For overcome the deficiencies in the prior art, set for the gas circuit in the medical rehabilitation apparatus of existing prevention phlebothrombosis
Meter, the utility model provide a kind of valve connector of buffering air pressure.The utility model uses the design of vortex structure, can be effective
Impact of the ground buffer gas to equipment, and reduce the frictional force of gas and equipment, while gas is also reduced in motion process
Caused noise.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
The valve connector of a kind of buffering air pressure, from top to bottom successively by intake interface, vortex structure, outlet interface group
Into, outside the vortex structure by a bottom down and lower ending opening cone form, inwall is provided with guiding gutter, described to lead
Gas can be flowed to form vortex from the top down, the intake interface is connected to vortex knot by chute in helical form along inwall
The side of structure, the outlet interface are connected to the bottom surface of vortex structure, and gas enters vortex structure and then from going out by intake interface
Gas interface flows out, and the junction of the outlet interface and vortex structure is additionally provided with annular fixed seat, and the annular fixed seat is set
It is equipped with neck.After the excessive gas of air pressure enters vortex structure from air inlet, according to the design of vortex structure, guiding gutter draws
Conductive gas forms unidirectional vortex, is gone out after buffer gas flow velocity from gas outlet, enters in the equipment being adapted with valve connector.
Further, the neck sets the both sides of annular fixed seat, the screens phase corresponding with external connection apparatus
Match somebody with somebody, the assembling for the equipment being adapted for valve connector with outside.
Further, sealing ring is provided with below the annular fixed seat, the sealing ring is close to annular fixed seat and gone out
Gas interface outer wall.Sealing ring plays a part of sealing in valve connector and other equipment connection procedure so that whole gas circuit
Air-tightness it is more preferable.
Further, the inwall of the cone at least three groups of identical guiding gutters are arranged side by side, and the guiding gutter is in
Helical form, the presence of multigroup guiding gutter have the formation for beneficial to water conservancy diversion to greatest extent, promoting vortex.
Further, the intake interface is cylindric in a ring, and the intake interface and vortex structure side are close to bottom surface
The angle of side is 55 ° ~ 85 °.
Further, the outlet interface is cylindric in a ring, connects completely with vortex structure bottom surface and perpendicular to vortex
The bottom surface inner ring radius of structure floor, its inner ring radius and vortex structure is essentially equal, ensures that linking is close.
Further, the inner ring radius of the outlet interface is more than the inner ring radius of the intake interface, further slow
The air pressure of gas is rushed.
The utility model is light compact, easy to operate, adapts in medical environment complicated and changeable, has good market
Prospect, following beneficial functional can be achieved：
Vortex is applied in valve connector by the utility model, and compressed gas carries out vortex structure, circle by air inlet
Cone structure makes air-flow flow to form vortex along centrum inwall, realizes the effect of buffer gas flow, reduces gas and connector
Noise caused by friction, the impact for the equipment that air-flow pair is connected with connector is reduced, reduce gas and the frictional force of the equipment, drop
The loss of the low equipment, extend the service life of the equipment.
