Abstract

The utility model relates to the technical field of a pipeline connecting piece, in particular to a novel air pipe connector which comprises a body pipe and a sealing ring, wherein a reversed hook groove and a containing groove are molded on the head of the body pipe, and the containing groove is internally provided with the elastic sealing ring. The novel air pipe connector has simple structure and design, and no air leakage under the condition of thermal expansion and contraction, and does not easily have faults.

Description

A kind of novel tracheae connecting head

Technical field:

The utility model relates to the pipe joint technical field, refers in particular to a kind of novel tracheae connecting head.

Background technique:

At present, can be commonly used in chiller plant to the tracheae connecting head, the tracheae connecting head is connected on the pipe, main rising transferred, the effect of shunting, there is certain problem in existing tracheae connecting head in the design of connection mouth, the connection mouth of tracheae connecting head (1A) all is to be designed to barb-shaped groove (2A), as shown in Figure 1, because the external stability of tracheae connecting head has pipe, tube exterior is provided with anchor ear and fixes, pipe generally is a rubber pipe, because the existence of expanding with heat and contract with cold, pipe can produce the space with connection mouth during shrinkage, the situation that has gas leakage takes place, internal gas can not seal fully, will allow machine works undesired like this, influences machine and runs well.

The model utility content:

The purpose of this utility model is to provide a kind of novel tracheae connecting head at the deficiencies in the prior art, and its structural design is simple, and the situation that can not leak air under the situation of expanding with heat and contract with cold is not easy to break down, and can solve the sealing problem of pressurized gas.

For achieving the above object, the utility model adopts following technological scheme: it comprises body tube, seal ring, and the head of body tube is formed with barb groove, containing groove, is provided with the rubber-like seal ring in the containing groove.

Described body tube is a hollow tube.

Described seal ring is a rubber ring.

Described body tube is the above body of at least one connecting head.

The utility model beneficial effect is: the head of body tube is formed with barb groove, containing groove, be provided with the rubber-like seal ring in the containing groove, tube inner wall can seal with seal ring, there is not the space to produce, the situation that does not have gas leakage takes place, will allow machine works normal like this, not influence machine and run well stable performance.

Fig. 2 is a sectional view of the present utility model;

Fig. 3 is the sectional view that the utility model removes seal ring;

Fig. 4 is a structural representation of the present utility model;

Fig. 5 is a decomposition texture schematic representation of the present utility model;

Fig. 6 is the structural representation of the another kind of mode of execution of the utility model.

Embodiment:

See that Fig. 1 is to shown in Figure 6: the utility model comprises body tube 1, seal ring 4, and the head of body tube 1 is formed with barb groove 2, containing groove 3, is provided with rubber-like seal ring 4 in the containing groove 3.

Described body tube 1 is a hollow tube.

Described seal ring 4 is a rubber ring.

Described body tube 1 is the above body of at least one connecting head, as shown in Figure 6.

The utility model is connected wants (as the tracheae of idle call) on the machine pipes, be fixed on the outside of pipe with anchor ear, because seal ring 4 be rubber ring, seal ring 4 and tube inner wall be by elastic strain, is close to mutually and seals, tube inner wall can seal with seal ring, do not have the space to produce, the situation that does not have gas leakage takes place, and will allow machine works normal like this, do not influence machine and run well stable performance.

The utility model can be widely used in various, on the gas transfer tube of chiller plant, air compressor, can guarantee the normally unimpeded of gas.

The above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
