CN203757269U - Novel independent sealing corrugated pipe compensator - Google Patents

Abstract

The utility model provides a novel independent sealing corrugated pipe compensator. The novel independent sealing corrugated pipe compensator comprises a compensating pipe body, wherein the middle part of the compensating pipe body is provided with a corrugated pipe, an L-shaped rubber block is arranged on the compensating pipe body at each of two sides of the corrugated pipe, and the two L-shaped rubber blocks are arranged in a reverse mutual buckling way. According to the novel independent sealing corrugated pipe compensator provided by the utility model, the corresponding ends, which are provided with hooks, of the two L-shaped rubber blocks can be mutually buckled together through arranging the two L-shaped rubber blocks in the mutual buckling way, the corrugated pipe can be effectively sealed, dust, sandy soil particles and the like are prevented from falling in gaps of the corrugated pipe, and thus the stretching and the heat dissipation of the corrugated pipe are not influenced; meanwhile, through the flexible connecting arrangement of the novel independent sealing corrugated pipe compensator, when the corrugated pipe stretches, the sealing effect is ensured to be unchanged while the two L-shaped robber blocks move along with the stretching of the corrugated pipe; the integral structure is simple and reliable, the design is skillful, the cost is low, and direct upgrading and reconstructing can be carried out on the basis of an original corrugated pipe compensator, and the novel independent sealing corrugated pipe compensator is beneficial for being promoted and used in a large scale.

Description

A kind of novel independent sealed corrugated expansion joint

Technical field

The utility model relates to a kind of compensator, the novel independent sealed corrugated expansion joint of especially a kind of good sealing effect, long service life.

Background technique

In heating power heat supply ductwork, often need to carry out compensation of pipeline, conventional bellow type compensator and the slip-type expansion joint of mostly being.But because of work under bad environment, in the gap of bellow type compensator, tend to fall into the impurity such as sandy soil particle, affect the flexible and heat radiation of bellows.

Model utility content

For addressing the above problem, the utility model provide a kind of simple and reliable for structure, flexibly connect and the novel independent sealed corrugated expansion joint of good sealing effect, long service life.

Realize the novel independent sealed corrugated expansion joint of one of the utility model object, comprise expansion pipe body, described expansion pipe body middle part is provided with bellows, on the expansion pipe body of described bellows both sides, be respectively provided with a L shaped block rubber, described two L shaped block rubbers are reverse mutual button entry type setting.

The novel independent sealed corrugated expansion joint of one described in this patent, by two L shaped block rubbers are carried out to mutual button entry type setting, make one end of its buckle mutually close and be buckled together, bellows effective sealing can be got up, prevent that dust and sandy soil particle etc. from dropping in bellows crack, affect bellows and stretch and dispel the heat; Meanwhile, it flexibly connects setting, can ensure that bellows stretches time, when two L shaped block rubbers can follow-up shift, ensures that sealing effect is constant.

This patent overall structure is simple and reliable, designs ingeniously, with low cost, can on original basis, directly carry out upgrading, is conducive to large-scale promotion and uses.

Brief description of the drawings

Fig. 1 is the structural representation of a kind of novel independent sealed corrugated expansion joint of the present utility model.

Embodiment

As shown in Figure 1, the novel independent sealed corrugated expansion joint of one of the present utility model, comprise expansion pipe body 3, described expansion pipe body 3 middle parts are provided with bellows 2, on the expansion pipe body 3 of described bellows 2 both sides, be respectively provided with a L shaped block rubber 1, described two L shaped block rubbers 1 are reverse mutual button entry type setting.

The novel independent sealed corrugated expansion joint of one described in this patent, by two L shaped block rubbers 1 are carried out to mutual button entry type setting, make one end of its buckle mutually close and be buckled together, bellows 2 effective sealings can be got up, prevent that dust and sandy soil particle etc. from dropping in bellows 2 cracks, affect bellows 2 and stretch and heat radiation; Meanwhile, it flexibly connects setting, can ensure that bellows 2 is flexible time, when two L shaped block rubbers 1 can follow-up shift, ensures that sealing effect is constant.

This patent overall structure is simple and reliable, designs ingeniously, with low cost, can on original basis, directly carry out upgrading, is conducive to large-scale promotion and uses.

Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in related domain make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
