Abstract
The utility model relates to the improvement on a tube clip valve of a rubber tube, and is characterized in that an original straight flexible tube in a valve is changed into a ripple-shaped tube, the shaft direction tension deformation of the rubber tube caused during the on-off process of the valve obtains effective compensation, and the damage of the tube clip valve caused by the tension fatigue of the rubber tube is avoided. A clip flat section and a growth-limited ring on the ripple-shaped tube further improve the service life of the ripple-shaped tube.
Description
Model utility is about the improvement to the sebific duct pipe clip valve.
Pipe clip valve is to rely on the interior flexible sebific duct of valve under external force pinching to be pressed sebific duct to be out of shape to reach to open and close to dam, and the flexible sebific duct that uses in the pipe clip valve is straight shape pipe usually.Because valve opens and closes frequent, open and close distortion big (especially heavy caliber valve), and the nose balance of straight shape pipe is limited in one's ability, therefore in use easily causes the sealed at both ends shirt rim of sebific duct fatigue damage and/or sebific duct root to pull, thereby this pipe clip valve operational safety is poor, the life-span short.
The purpose of model utility is to overcome the deficiency of above-mentioned prior art, provides a kind of and has larger axis to compensation, can avoid causing the pipe clip valve that sebific duct fatigue damage and sealing shirt rim root are pulled because of valve frequently opens and closes, is out of shape to stretch.
Another purpose of model utility be to provide a kind of to clip closure the time pipe clip valve of fragile ripple not.
The another purpose of model utility is to provide a kind of pipe clip valve of bellows contract radial expansion friction valve body can effectively prevent opening of valves the time.
The model utility purpose realizes, the main improvement is to make the straight shape flexible pipe in valve Central Plains into bellows, the flexible pipe that make overcurrent like this, dams has bigger nose balance ability, thereby the distortion that makes sebific duct in the valve opening-closing process stretches and is compensated, the generation of having avoided fatigue damage and having pulled has prolonged working life of pipe clip valve.
Model utility pipe clip valve sebific duct for reducing because of valve rod damages distortion and improves sealing effect folder position ripple the life of pinching Hair Fixer, can be provided with one than wide flat section of ripple to the folder position at bellows.Bellows-shaped can be rectangular wave, triangular wave, circular arc ripple.When preventing opening of valves, because of ripple axial shrinkage and tube fluid pressure.Cause that bellows radially expands, and make bellows and valve body friction, can on the bellows trough, overlap limited piston ring.
Below in conjunction with an indefiniteness embodiment's description, further specify model utility and advantage.
Fig. 1 is a model utility bellows pipe clip valve structural representation.
Fig. 2 is a model utility triangle ripple pipe schematic representation.
Fig. 3 is a model utility rectangle bellows schematic representation.
Embodiment: pipe clip valve mainly contains valve body 1 bellows 2 two parts and forms.Anchor clamps position, bellows middle part has one than wide flat section 4 of ripple, damages ripple when avoiding anchor clamps to folder, improves and blocks sealing effect.Flat section is provided with anchor clamps groove 5.Bellows radially expands and the valve body friction when preventing opening of valves, the limited piston ring 3 of cover on the bellows trough.When valve cut out, valve rod drove anchor clamps to folder, makes the bellows closure, reach the effect of damming, bellows closed cause that the axial tension of pipe is then compensated by ripple, during opening of valves, the bellows axial shrinkage is not because limit piston ring position-limiting action radially expands and can not produce bellows.
The model utility pipe clip valve makes that the axial tension of the sebific duct that valve causes is effectively compensated owing to adopt the corrugated flexible pipe when opening and closing, thereby has overcome straight tube easily because of opening and closing the damage that distortion stretches and causes.On the bellows to the limit piston ring on folder flat section of the position and the trough, the working life of having improved bellows especially.
For convenience of description, sebific duct and flexible pipe are synonym in the model utility specification.
