Abstract
The utility model relates to a one-way valve, in particular to a bi-directional free transform one-way valve. The bi-directional free transform one-way valve comprises a stator and a rotor, wherein a sealed channel is arranged in the outer portion of the stator, and the one-way valve is arranged in the inner portion of the rotor. Through an organic integration of the outer stator, the inner rotor and the one-way valve which comprises a round ball and a spring in the inner portion of the rotor. In the meantime of achieving one-way ventilation, a one-way ventilating direction transformation and a starting function and a closed function of the valve can be achieved through rotation of the rotator. And therefore redundancy of using two one-way valves can be avoided, cost can be saved, size of a device can be reduced, structure can be simplified, installing time can be saved and unnecessary disassembling can be avoided.
Description
Technical field
The utility model relates to one-way cock, specifically a kind of valving with one-way ventilating function that can freely change on both direction.
Background technique
In existing one-way cock, can only realize gas or the flow of fluid of a direction, want to flow in the opposite direction, valve must be unloaded above relevant match equipment, and then carry out rightabout installation, can realize the one-way flow of reciprocal gas or liquid.Such as practical novel C N95209095.3, CN2309466Y and CN98221870.2 etc., these structures can solve the problem of the one way flow of control gas or liquid to a certain extent, but can exist structure comparatively complicated, and by the gas backstreaming throttle down, tightness is not strong, can not realize at same valve in addition the transformation of gas or liquid one-way flowing direction.
The model utility content
The purpose of this utility model is to design a kind of valving, make it when realizing the valve one-way ventilating, can realize by the rotation of its rotor the transformation of one-way ventilating direction, also can select the unlatching of ventilatory function or close, thereby the redundancy of avoiding two one-way cocks to use is cost-saved, reduces the volume of device, simplify structure, save the installation time and avoid unnecessary dismounting.
For achieving the above object, this practical new technological scheme is:
The two-way one-way cock of freely changing, the described two-way one-way cock of freely changing is comprised of with inner rotor with one-way cock the stator of outside with closed channel.Wherein be provided with two ports that connect the inlet, outlet pipeline above the stator, port connects the passage of quadrant in stator.Rotor is the round pie of a sealing, and the diameter place is that two ends are narrower, the pipeline of wide middle, and an end is put a ball in the pipeline, and the diameter of this ball is placed a spring below the ball between wide pipeline and thin pipe diameter.By the combination of the ball in stator, rotor and the rotor and spring, when realizing one-way ventilating, can realize by the rotation of rotor the transformation of one-way ventilating direction and closing and opening of valve.
When the rotation by rotor makes one-way cock and upper and lower port point-blank, air-flow promotes ball and Compress Spring, make air flow energy flow to lower end mouth from upper end-hole, when the rotor counter-rotating was vertical with upper and lower port to one-way cock, ball was blocked pipeline under the elastic reaction of spring, make air-flow flow to lower end mouth from upper end-hole, when if air-flow enters from lower end mouth, gas will promote the ball Compress Spring, make air-flow flow to upper end-hole from lower end mouth, realize the reverse of airflow direction.
When realizing the valve one-way ventilating, can realize by the rotation of its rotor the transformation of one-way ventilating direction.
When rotor to the suction port of one-way cock and air outlet all blocked by the enclosure portion of stator, the ventilatory function of valve was closed.

Embodiment
The below further specifies the utility model by reference to the accompanying drawings.
Description of reference numerals:
1---upper end-hole
2---lower end mouth
3---the enclosure portion of inner rotator
4---the enclosure portion of outer stator
5---arrow represents the control gas flow direction of one-way cock
6---the ball of one-way cock inside
7---the spring of one-way cock inside
8---the sense of rotation of rotor
Referring to accompanying drawing.When two-way when freely changing one-way cock and being in position shown in Figure 1, one-way cock and upper and lower port 1,2 are point-blank, when not having gas flow or gas to flow to upper end-hole 1 from lower end mouth 2, spring 7 is pushed into pipe end by the elasticity of self with ball 6, thereby close epitrochanterian passage, so that gas can not flow.When gas flowed to lower end mouth 2 from upper end-hole 1, gas push ball 6 moved down, thereby Compress Spring 7 is shown in dotted line, thereby gas can flow to lower end mouth 2 from upper end-hole 1.
When the rotor of inside rotated to as shown in Figure 2 the position in the counterclockwise direction, the suction port of internal rotor one-way cock and air outlet were all blocked by the enclosure portion 4 of stator, the ventilatory function of throttle down.
When the rotor of inside rotates to as shown in Figure 3 the position in the counterclockwise direction, if gas enters from upper end-hole 1, ball 6 will be blocked pipeline under the elastic reaction of spring 7, so that gas can not flow to lower end mouth 2 from upper end-hole 1.When gas enters from lower end mouth 2, gas will promote ball 6 Compress Springs 7 to dotted line position, and the air-flow port one direction that makes progress flows.Thereby realize the one-way ventilating of lower end mouth 2 supreme port one directions.
The organic combination of the one-way cock that is comprised of ball and spring by outer stator, inner rotator and internal rotor when realizing one-way ventilating, can be realized by the rotation of rotor the transformation of one-way ventilating direction and the closing function of valve.Thereby the redundancy of avoiding two one-way cocks to use is cost-saved, reduces the volume of device, simplifies structure, saves the installation time and avoids unnecessary dismounting.
The utility model not only is confined to Fig. 1,2,3 structure, and the two-way one-way cock of freely changing both can be done glomeration, also can make pie, and inner one-way cock also can make other constructional device into, may not be that ball adds this device of spring.Above 26S Proteasome Structure and Function etc. all is considered as extension of the present utility model, as long as the technological scheme similar to the utility model 26S Proteasome Structure and Function, all at protection domain of the present utility model.
