Adopt flange joint's mode between current valve and the pipeline, operating personnel locks fixedly through 6 ~ 10 bolts and lock mother with the flange on valve and the pipeline, and this kind of mounting means's shortcoming lies in, needs two operating personnel to operate, simultaneously, needs operating personnel to carry out single bolt and passes the through-hole on the flange and fix a position, and its installation effectiveness is lower.
The invention content is as follows:
the utility model discloses the technical problem that will solve is: the valve flange structure for the quick connection of the pipelines is high in installation efficiency.
In order to solve the technical problems, the invention is realized by the following technical scheme: a valve flange structure for fast connection of pipelines comprises a valve main body, a first flange, a guide ring, a screw rod, a pushing ring, a stop ring, a locking nut, a pipeline and a second flange, the first flange is integrally arranged at two connecting ends of the valve main body, the second flange is integrally arranged on the pipeline, the guide ring is fixedly arranged on the connecting end of the valve main body, a plurality of screw rods are distributed in an annular array and are slidably arranged on the guide ring, the first flange and the second flange are correspondingly provided with through holes matched with the screw rod, the stop ring is fixedly arranged on the screw rod in an integrated forming way, and the stop ring is positioned at the left side of the guide ring, the push ring is arranged at the right side of the guide ring, the screw rod left end slides and passes the through-hole that sets up on first flange and the second flange, lock nut spiro union fixed mounting is at the left end of screw rod.
Preferably, the pushing ring is annularly provided with a positioning blind hole matched with the right end of the screw rod.
Preferably, the right end of the screw is provided with a bevel structure.
Preferably, the pushing ring is screwed with a pressing bolt for pressing and fixing the pushing ring on the connecting end of the valve body.
Preferably, the stop ring is arranged in a regular hexagonal structure, and a limit groove matched with the stop ring structure is arranged on the inner side of the first flange.
Preferably, the first flange and the second flange are respectively and fixedly provided with a sealing ring which is matched with the first flange and the second flange.
Compared with the prior art, the utility model discloses an useful part is: when operating personnel is connected first flange on to the valve main part and the second flange of pipeline, at first adjust well the through-hole on first flange and the second flange, then operating personnel promotes to impel the ring once only can with all screw rods in the through-hole on first flange and the second flange, operating personnel will lock the nut one by one fasten the screw rod on can, this flange structure has the advantage that simple operation and installation effectiveness are high.
Description of the drawings:
the present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention.
