Abstract
A gas conduit service connector comprises a connector, a service inlet tube, a pressing cover, a support ring and a seal ring, wherein a service connecting tube is disposed on the connector. The outer wall of the service connecting tube is provided with external threads and the inner wall of the service connecting tube is provided with internal threads. An outwards inclined flare groove is disposed on the edge of the inner wall of the service connecting tube. The seal ring is built in the flare groove. The support ring is disposed in the pressing cover. The pressing cover threads is connected with the outer wall of the service connecting tube, and the service inlet tube is sequentially penetrated in the pressing cover, the support ring and the seal ring. The threads is connected with the inner wall of the service connecting tube, and the pressing cover is twisted tightly for leading the support ring to tightly press the seal ring thereby forming the gas conduit service connector. The utility model is convenient to install and repair, is uneasy to leak due to the duplicate seal of the flare seal ring and the elastic pressing support ring, can hide screw thread, can promote the corrosion resisting property and can prolong the service life.
Description
Technical field
The utility model relates to pipe joint, particularly relates to gas pipe line house lead in link.
Background technique
In the gas pipe line construction at present, constantly employ new technology, improved the Security of pipe-line system operation greatly, but also had unsafe factor in the part, especially accident to leak the coal gas takes place in link in garden pipeline and house lead in inlet tube joint easily.Garden pipeline and the connecting means of house lead in inlet tube now: be to be split into a vent, go up pipe clamp in the encapsulation of vent place again and be connected, or connect garden pipeline and house lead in inlet tube by the three-way pipe of house lead in the house lead in inlet tube in garden pipeline house lead in place.Be connected between above-mentioned garden pipeline and the house lead in inlet tube to adopt usually and be threaded, it is threaded in the process, often make the tight spiral shell button in school move back button when registering one's residence the position and can cause leakage for adjustment, the length of screw thread cover is difficult for again grasping in the construction, destroyed and the screw thread portion of long its zinc-plated anticorrosive coat of hitch is exposed to is very easily corroded outward, and tube wall attenuate mechanical strength weakens, in variation of ambient temperature and being subjected under the effect of external force, the screwed connection position is returned and is subjected to push-and-pull again, cause stress to concentrate, cause rupturing, bring dangerous greatly to resident family.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of good sealing effect, is difficult for leaking, and screwed connection place is difficult for rupturing, and is easy for installation, guarantees the gas pipe line house lead in link of safety.
The technological scheme that adopts is:
Gas pipe line house lead in link comprises link body, house lead in inlet tube, gland, bracing ring and seal ring.Described link body is provided with house lead in and takes over, house lead in is taken over outer wall and is provided with outside thread, the house lead in nozzle inner wall is provided with internal thread, house lead in nozzle inner wall edge is provided with outward-dipping flare groove, the flare groove embedded seal ring, gland built-in hold support ring, gland is threaded in the house lead in of link body and takes on the outer wall, the house lead in inlet tube is installed in gland, bracing ring and the seal ring successively, be threaded on the house lead in nozzle inner wall of link body, screw gland bracing ring is pressed on the seal ring, constitute gas pipe line house lead in link.
The outer ring of above-mentioned seal ring is set as tubaeform inclined-plane, and the outward-dipping flare groove that its tubaeform inclined-plane and house lead in nozzle inner wall edge are provided with is complementary.
The outer ring of above-mentioned bracing ring is set as tubaeform inclined-plane, bracing ring vertically be provided with a gap, but constitute the bracing ring of elastic compression.
Be provided with outward-dipping flare groove in the above-mentioned gland, the tubaeform inclined-plane that its flare groove and bracing ring outer ring are set as is complementary.
The utility model installation, maintenance is convenient, adopts the flared structure seal ring tighter with the bracing ring two seals with elastic compression, is difficult for leaking, and screw thread does not expose, and has improved corrosion resistance, increases service life.
