Description
Technical field
The utility model relates to pneumatic components and parts technical field, particularly relates to the Pneumatic pipe valve seals that a kind of resistance is little.
Background technique
Pneumatic pipe valve is the professional pneumatic joint being applied to numerical controlled machinery equipment, requirement can quick-replaceable joint, and sealing requirements is high, use in practice and prove rear discovery, existingly be applied to seal ring in pneumatic joint when tracheae carries out quick insertion, due to the reason that area of contact is excessive, larger resistance can be caused, and due to this resistance, rub large reason, and the situation of failing on earth when tracheae can be caused to insert, can produce the situation of micro-leakage, also can reduce the working life of seal ring and tracheae, improve cost of production.
Model utility content
The purpose of this utility model is the Pneumatic pipe valve seals providing a kind of resistance little, its have reduce resistance, reduce friction area thus improve tracheae insert smoothness and prevent leak gas feature.
For achieving the above object, the utility model adopts following technical proposals:
The Pneumatic pipe valve seals that a kind of resistance is little, comprise seal ring main body, described seal ring main body outer lower portion is provided with press-in flange collar, described seal ring main body inside upper part is provided with pressure ring groove, described seal ring main body lower inside is provided with sealing inclined-plane, the upper end on described sealing inclined-plane is connected with pressure ring groove bottom, and described seal ring bottom part body offers stressed groove, and described stressed groove is U-shaped.
Wherein, the angle of inclination on described sealing inclined-plane is 15 ~ 45 degree.
Wherein, the top on described sealing inclined-plane is concordant with tracheae socket inner side surface.
Wherein, described sealing beveled top end and pressure ring groove joint rounding.
The utility model beneficial effect: the utility model comprises seal ring main body, described seal ring main body outer lower portion is provided with press-in flange collar, described seal ring main body inside upper part is provided with pressure ring groove, described seal ring main body lower inside is provided with sealing inclined-plane, the upper end on described sealing inclined-plane is connected with pressure ring groove bottom, described seal ring bottom part body offers stressed groove, described stressed groove is U-shaped, the utility model is rational in infrastructure, by arranging U-type groove bottom seal ring, be convenient to the backward interior extruding of pressurized, in addition sealing beveled top end is set to and rounding concordant with air pipe inlet, be convenient to when tracheae inserts very smooth and easy, bottom can be rapidly inserted into, reach better sealing effect, prevent gas leakage.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, the Pneumatic pipe valve seals that a kind of resistance is little, comprise seal ring main body 1, described seal ring main body 1 outer lower portion is provided with press-in flange collar 2, described seal ring main body 1 inside upper part is provided with pressure ring groove 3, described seal ring main body 1 lower inside is provided with sealing inclined-plane 4, the upper end on described sealing inclined-plane 4 is connected with pressure ring groove 3 bottom, stressed groove 5 is offered bottom described seal ring main body 1, described stressed groove 5 is U-shaped, described top, sealing inclined-plane 4 and pressure ring groove 3 joint rounding, by arranging U-type groove bottom seal ring, be convenient to the backward interior extruding of pressurized, in addition top, sealing inclined-plane 4 is set to and rounding concordant with air pipe inlet, be convenient to when tracheae inserts very smooth and easy, bottom can be rapidly inserted into, reach better sealing effect, prevent gas leakage.
In the present embodiment, the angle of inclination on described sealing inclined-plane 4 is 15 ~ 45 degree, and choose reasonable is carried out according to actual conditions in the angle of inclination on described sealing inclined-plane 4.
In the present embodiment, the top on described sealing inclined-plane 4 is concordant with tracheae socket inner side surface, and the top internal diameter on described sealing inclined-plane 4 also can be greater than the internal diameter of tracheae socket, with the smoothness reached, specifically selects according to actual conditions.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
