Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of linkage structure for bleeding device and gas pipeline be provided, solve existing diffuse channel and be connected on gas pipeline, install loaded down with trivial details, the defect that sealing effect is poor.
The present invention is achieved through the following technical solutions: for the linkage structure of bleeding device and gas pipeline, comprise the bypass duct that connects gas pipeline and the mounting head that is connected bleeding device, described mounting head comprises connecting tube, the stage casing of connecting tube is provided with an annular protrusion, on connecting tube, also cover has a threaded pipe, the external diameter of threaded pipe is greater than the external diameter of annular protrusion, wherein one end of threaded pipe is provided with catch ring, the internal diameter of catch ring is consistent with the external diameter of connecting tube, the both sides of annular protrusion are respectively arranged with a rubber ring, the external diameter of connecting tube coordinates with the internal diameter of bypass duct, connecting tube injects bypass duct, until stopped by annular protrusion, in bypass duct, be provided with the outside thread coordinating with threaded pipe, in bypass duct, be provided with one around the bypass duct barrier plate of a week, barrier plate is provided with rubber sleeve towards a side of mounting head.This device mounting type is: bypass duct one end is communicated with gas pipeline, leave a mouth of pipe, in general bypass duct, be provided with a valve, in the time not diffusing, valve closes, connecting tube one end is inserted in the mouth of pipe of bypass duct, the other end is connected to bleeding device, threaded tube is on connecting tube, catch ring is between annular protrusion and bleeding device, rotation threaded pipe, threaded pipe is threaded in bypass duct, the length of threaded pipe needs moderate, together with catch ring and annular protrusion, oppress the rubber ring between them, together with annular protrusion and bypass duct, oppress the rubber ring between them, at this moment, threaded pipe and barrier plate can together be urged to rubber sleeve, very good of sealing like this, first, connecting tube is inserted into bypass duct, both mate, determine sealing effect so another, then be the rubber ring between annular protrusion and bypass duct, it is second sealing, rubber ring between last catch ring and annular protrusion, rubber sleeve between threaded pipe and barrier plate, form three seals, the installation of this device is also very convenient, be threaded fixing.
Further, on above-mentioned threaded pipe, be provided with the anti-slip veins along its bearing of trend, facilitate staff to rotate threaded pipe, while preventing that the palm of the hand from having sweat, constantly skid, thereby twist not tight threaded pipe, have influence on sealing.
Further, above-mentioned catch ring is connected with threaded pipe is integrated; Annular protrusion is connected with connecting tube is integrated, has ensured join strength, be not easy to damage, and sealability is also best.
The invention has the beneficial effects as follows: this device is for the linkage structure of bleeding device and blast tube, and not only easy for installation, sealability is also very good.
