Description

Leak-proof stainless steel corrugated connecting pipe for gas conveying

Technical Field

The utility model belongs to the technical field of the technique of corrugated connection pipe and specifically relates to indicate a gas is carried and is used leak protection stainless steel corrugated connection pipe.

Background

At present, the bellows has widely been used in municipal administration, building engineering as a novel tubular product, often because of the particularity of its material, and the requirement for pipe end incision clearance is higher among the mouth of pipe connecting process, accomplishes closely the butt joint as far as possible, reduces the port clearance. In the construction, the corrugated pipe has large volume and heavy weight, so that the time for opening the pipeline is long and the difficulty is high. In addition, the slot is narrow in butt joint operation space, long-time hoisting matching of hoisting machinery is needed in pipeline butt joint operation, the butt joint precision is low, the construction safety risk is high, and the cost is high.

Bellows connecting pipe among the prior art generally only rotates tightly through rubber and screw ring, and such connected mode pine takes off easily, in case loosen easily the gas and reveal.

Disclosure of Invention

The utility model aims at providing a gas is carried and is used leak protection stainless steel ripple connecting pipe, it has the better effect that prevents that the gas from revealing and preventing to drop.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a gas is carried and is used leak protection stainless steel corrugated connection pipe, includes the connecting pipe body, the extension pipe has been stretched out at connecting pipe body both ends, extension pipeline and connecting pipe body integrated into one piece, a plurality of slots have been seted up on the both ends terminal surface that the extension pipe deviates from the connecting pipe, be provided with the rubber circle on the extension inside pipe wall, extension outside pipe wall threaded connection has the screw ring, the connecting pipe inner wall is provided with ring baffle, ring baffle and rubber circle and connecting pipe body inner wall are formed with the cavity in addition between the bellows outer wall, the cavity top is provided with the perforation.

Preferably, a rubber ring is clamped on one surface of the baffle, which is opposite to the corrugated pipe.

Preferably, the connecting pipe between the through hole and the cavity is provided with a ring groove on the inner wall of the connecting pipe, and the ring groove is coaxial with the connecting pipe body.

Preferably, the ring groove includes a plurality of grooves.

Preferably, the perforations are located at the top and bottom of the cavity, respectively.

Preferably, the inner wall of the threaded ring and the outer wall of the extension pipe are both wedge-shaped, and an included angle formed between the cross section of the threaded ring and the corrugated pipe is larger than an included angle formed between the cross section of the outer wall of the extension pipe and the corrugated pipe.

To sum up, the utility model has the advantages that:

at first when connecting, expose the bellows earlier, then put into this internal both ends of connecting pipe with the bellows and make its and baffle butt, then install the outer wall at the extension pipe with the screw thread of threaded pipe, then make the rubber circle of extension pipe inner wall press from both sides tight the bellows outer wall to fix the bellows at this internal arm of connecting pipe, then pour the cavity inside, thereby can make even the screw ring drops also can play the effect that prevents that the gas from revealing and fix equally.

Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a leak protection stainless steel corrugated connection pipe for gas is carried, including connecting pipe body 1, connecting pipe body 1 both ends are stretched out and are had extension pipe 11, extension pipe 11 and connecting pipe body integrated into one piece, a plurality of slots 111 have been seted up on the both ends terminal surface that extension pipe 11 deviates from the connecting pipe, be provided with rubber circle 112 on the extension pipe 11 inner wall, extension pipe 11 outer wall threaded connection has threaded ring 12, the connecting pipe inner wall is provided with ring baffle 13, be formed with cavity 14 between ring baffle 13 and rubber circle 112 and connecting pipe body 1 inner wall and the bellows outer wall in addition, cavity 14 top is provided with perforation 15.

The working principle is as follows: firstly, when connecting, expose the bellows earlier, then put into connecting pipe body 1 with the bellows both ends make it and baffle butt, then install the screwed pipe screw thread at the outer wall of extension pipe 11, then make the rubber circle 112 of extension inside pipe wall press from both sides tight the bellows outer wall to fixing the bellows at connecting pipe body 1 inner arm, then pour cavity 14 inside, thereby can make even the screw ring 12 drops also can play the effect that prevents that the gas from revealing and fix equally.

The baffle has rubber ring 131 to the centre gripping on the one side of bellows, adopts such structure can make the bellows can produce certain sealing performance when butt baffle, can produce comparatively sealed space.

The annular groove 16 is formed in the inner wall of the connecting pipe between the through hole 15 and the cavity 14, the annular groove 16 is coaxial with the connecting pipe body 1, and the structure can enable the interior of the cavity 14 to be poured so as to achieve a better waterproof function.

The ring groove 16 includes a plurality of grooves.

The perforations 15 are located at the top and bottom of the cavity 14, respectively, and are configured so that air bubbles are less likely to form inside the cavity 14 during casting.

The inner wall of the threaded ring 12 and the outer wall of the extension pipe are both wedge-shaped, and meanwhile, an included angle formed between the cross section of the threaded ring 12 and the corrugated pipe is larger than an included angle formed between the cross section of the outer wall of the extension pipe 11 and the corrugated pipe, so that the threaded ring 12 can clamp the rubber ring 112 more tightly by adopting the structure.

The above description is only for the preferred embodiment of the present invention, and the present invention is not limited to the above description, and although the present invention is disclosed in the preferred embodiment, it is not limited to the above description, and any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, but all the technical solutions of the present invention are within the scope of the present invention.
