Abstract
The utility model discloses an improved sealing structure for an air exchange chamber. An irregular-shaped sealing groove is positioned outside a pneumatic oil pump air exchange chamber, an irregular-shaped sealing ring and a three-hole gasket are sequentially cushioned on the irregular-shaped sealing groove from inside to outside, the irregular-shaped sealing ring is a round shape, a round hole is arranged in the center of the irregular-shaped sealing ring, the three-hole gasket is in a round shape, and three same round holes are arranged on the three-hole gasket. The irregular-shaped sealing ring is arranged between the pneumatic oil pump air exchange chamber and the three-hole gasket, so that the improved sealing structure is reliable in sealing and can bear frequent air exchange and vibration for a long time. The improved sealing structure can guarantee good sealing effects under the situation where the air exchange chamber works for a long time.
Description
Technical field
The utility model relates to the Pneumatic oil pump equipment technical field, is specially a kind of improvement structure of air-exchanging chamber sealing.
Background technique
Be sealed into asbestos-packing gasket between the pump head air-exchanging chamber of existing Pneumatic oil pump and three hole pads, in frequent ventilation and vibration processes, the asbestos rubber pad easily produces breakage and leaks gas.
The model utility content
The purpose of this utility model is to overcome the shortcoming and defect of prior art, and a kind of improvement structure of air-exchanging chamber sealing is provided, and adopts safe and reliable seal form, prevents that air-exchanging chamber from leaking air, to reduce maintenance.
The improvement structure of a kind of air-exchanging chamber sealing of the present utility model is achieved through the following technical solutions:
A kind of improvement structure of air-exchanging chamber sealing has a profiled seal ring recess outside the Pneumatic oil pump air-exchanging chamber, be lined with successively from inside to outside special-shaped seal ring and three hole pads on this profiled seal ring recess.
As preferably, described special-shaped seal ring is that circular central has a circular hole.
As preferably, described three hole pads are circular, and the above has three identical circular holes of size.
Compared with prior art, the beneficial effect of the improvement structure of a kind of air-exchanging chamber sealing of the present utility model is: adopt the special-shaped seal ring sealing between Pneumatic oil pump air-exchanging chamber and three hole pads, thereby guarantee the reliability of sealing and can stand long-time frequent ventilation and vibration, guarantee that air-exchanging chamber still can have good sealing effect in the situation that work long hours.
Description of drawings
Below by embodiment, by reference to the accompanying drawings the utility model is further described.
Fig. 1 is the cross-sectional view of pump head;
Fig. 2 is the structural representation of profiled seal ring recess of the present utility model;
Fig. 3 is the structural representation of special-shaped seal ring of the present utility model;
Fig. 4 is the structural representation of three hole pads of the present utility model;
1 is the Pneumatic oil pump air-exchanging chamber, and 2 is the profiled seal ring recess, and 3 is special-shaped seal ring, and 4 is three hole pads.
Embodiment
As shown in Fig. 1-4, a kind of improvement structure of air-exchanging chamber sealing has a profiled seal ring recess 2 outside Pneumatic oil pump air-exchanging chamber 1, be lined with successively from inside to outside special-shaped seal ring 3 and three hole pads 4 on this profiled seal ring recess 2.Described special-shaped seal ring 3 is circular, and there is a circular hole at the center.Described three hole pads 4 are circular, and the above has three identical circular holes of size.
Adopt special-shaped seal ring 3 sealings between Pneumatic oil pump air-exchanging chamber 1 and three hole pads 4, thereby guarantee the reliability of sealing and can stand long-time frequent ventilation and vibration, guarantee that air-exchanging chamber still can have good sealing effect in the situation that work long hours.
Above-described embodiment; it is an example of the present utility model; be not to limit enforcement of the present utility model and interest field, all or technological schemes of being equal to identical with the described content of the utility model claim all should be included in the utility model protection domain.
