Automatic plugging valve for pipeline bursting

Abstract

The invention relates to the technical field of pipeline protection equipment, in particular to an automatic plugging valve for pipeline bursting. Related workers are not needed for manual control operation, waste of a large number of manpower resources is not needed, the using boundedness is low, and the practicability is higher; position movement is facilitated, the using flexibility is higher,and therefore the using reliability of the automatic plugging valve is improved; the automatic plugging valve comprises two first flange connecting discs, a second flange connecting disc, two bolts, aspring and a sealing plate, and the bottom end of the spring is connected with the top end of the sealing plate; and the automatic plugging valve further comprises a base plate, two servo motors, twosupporting rods, two upper fixing supports, two lower fixing supports, two rotating rollers, a transmission belt, a fixing block, a tower, an engine room, an electric generator, a transmission mechanism and a power storage motor, the two first flange connecting discs are installed on the left side wall and the right side wall of the base plate correspondingly, the transmission belt is arranged onthe two rotating rollers in a sleeving manner, the top end of the spring is connected with the bottom end of the fixing block, the power storage motor is electrically connected with the output end ofthe electric generator, and four rollers are further included.

Description

technical field [0001] The invention relates to the technical field of pipeline protection equipment, in particular to an automatic sealing valve for pipeline burst. Background technique [0002] As we all know, the pipe burst sealing valve is a device that seals the crack of the burst pipe to prevent a large amount of leakage of related materials, thereby protecting the interests of related enterprises. It is widely used in the field of related product production; the existing pipeline The burst sealing valve includes two sets of first flange connecting plates, second flange connecting plates, two sets of bolts, body, fixing rod, two sets of buckles, springs and sealing plates, and the two sets of first flange connecting plates They are respectively installed on the left side wall and the right side wall of the machine body, and two sets of first threaded holes are respectively arranged on the two sets of first flange connection plates, and the left side wall and the right ...

[0002] As we all know, the pipe burst sealing valve is a device that seals the crack of the burst pipe to prevent a large amount of leakage of related materials, thereby protecting the interests of related enterprises. It is widely used in the field of related product production; the existing pipeline The burst sealing valve includes two sets of first flange connecting plates, second flange connecting plates, two sets of bolts, body, fixing rod, two sets of buckles, springs and sealing plates, and the two sets of first flange connecting plates They are respectively installed on the left side wall and the right side wall of the machine body, and two sets of first threaded holes are respectively arranged on the two sets of first flange connection plates, and the left side wall and the right side of the second flange connection plate are respectively There are two sets of second threaded holes, a working cavity is set in the body, and two sets of clamping plates are respectively set on the left side wall and the right side wall of the working cavity, the top of the spring and the fixing rod The bottom end is connected, the bottom end of the spring is connected with the top end of the sealing plate, and the fixing rod is located in the working chamber; when this kind of pipeline burst sealing valve is used, the second flange connection plate is placed under the working pipeline, and the two A set of bolts is screwed and passes through two sets of second threaded holes and two sets of first threaded holes to fix the position of the body. When the pipe bursts, the user moves the fixing rod downward to drive the spring and at the same time drives the sealing plate to move down to the pipe It is enough to block the burst, and rotate the fixed rod to drive the two sets of buckles to move to the bottom of the two sets of clamps; It consumes a lot of human resources, has high limitations of use, and low practicability; moreover, it is inconvenient to move the location, and the flexibility of use is low, resulting in low reliability of use
