Abstract
The utility model relates to an automatic mine gas plugging device, comprising a pair of pipe joints, a connecting pipe, a spring leaf rubber sleeve, a tension sleeve and a locking clamp. The automatic mine gas plugging device is characterized in that the pair of pipe joints are connected with two ends of the connecting pipe respectively; the spring leaf rubber sleeve is sheathed outside the position where the upper pipe joint is connected with the upper end of the connecting pipe; the tension sleeve is sheathed outside the position where the lower pipe joint is connected with the lower end of the connecting pipe; and the locking clamp is clamped on an anti-rotation plate distributed on the pair of pipe joints and the connecting pipe. As the spring leaf rubber sleeve of the automatic mine gas plugging device is sheathed outside the position where the upper pipe joint is connected with the upper end of the connecting pipe, and the spring leaf rubber sleeve has sufficient elasticity and strength after being tensioned to open, good sealing effect is guaranteed, and the plugging depth range is large; as the tension sleeve is sheathed outside the position where the lower pipe joint is connected with the lower end of the connecting pipe, the tension sleeve plays the roles of self fastening and preventing the displacement of a pipeline, so that the self-sealing and self-fastening purposes are achieved; and the automatic mine gas plugging device is suitable for automatic plugging of mine gas of rock surfaces at various angle; and the automatic mine gas plugging device has reasonable design, is convenient to mount, and has low production cost.
Description
Technical field
The utility model relates to the gas plugging device, exactly is a kind of gas in mine automatic sealing device.
Technical background
The sealing of gas tube peripheries such as the gas in mine plugging device is mainly used under the coal mine, oil gas field, natural gas.The tradition sealer adopts air sac sealing, and the cost height is produced in the not only easy explosion of air bag, and because can not be from solid, the easy play of pipeline, so sealing effectiveness is poor, installation strength is big.
The utility model content
The utility model purpose is at the existing defective of gas plugging device, to people provide a kind of not only easy for installation, cost of production is low, plugging effect good, and seal depth bounds big, can be self-styled, solid certainly and be applicable to the scar gas in mine automatic sealing device of various angles.
The utility model comprises pair of pipes joint, tube connector, spring leaf rubber sleeve, tensioner cover and locking card, it is characterized in that: the pair of pipes joint is connected with the tube connector two ends respectively, the spring leaf rubber sleeve is placed in the outside that union is connected with the tube connector upper end, the tensioner cover is placed in the outside that lower pipe connection is connected with the tube connector lower end, and locking is stuck on the torsional stop that is arranged on pair of pipes joint, the tube connector.
The described union top of going up is provided with a boss, and a boss is arranged at the tube connector bottom, and the spring leaf rubber sleeve that interior periphery is embedded with spring leaf is placed between union and tube connector two boss.
Interior tensioner cover lower port has at least three gap.
A stay cord is equipped with in locking card upper end.
Effect of the present utility model
1, the utility model is because the spring leaf rubber sleeve is placed in the outside that union is connected with the tube connector upper end, has enough elasticity and intensity behind the spring leaf rubber sleeve spreading, thereby guaranteed good sealing effectiveness, and it is big to seal depth bounds, be placed in the outside that lower pipe connection is connected with the tube connector lower end because of the tensioner cover again, the tensioner cover plays from solid effect, prevents the pipeline play, thereby has realized self-styled, solid certainly and be applicable to the scar gas in mine automatic sealing of various angles.
2, the utility model is reasonable in design, and is easy for installation, and cost of production is low.

The specific embodiment
Embodiment 1:
(referring to Fig. 1～4) the utility model comprises the pair of pipes joint, tube connector 1, spring leaf rubber sleeve 2, tensioner cover 3 and locking card 4, the pair of pipes joint is connected with tube connector 1 two ends respectively, make by well behaved neoprene oil resistant rubber, interior periphery is embedded with the 65Mn spring leaf, can guarantee enough elasticity and intensity behind the spreading, the spring leaf rubber sleeve 2 that guarantees good sealing effectiveness is placed in the outside that union 5 is connected with the tube connector upper end, last union top is provided with a boss 8-1, one boss 8-2 is arranged at the tube connector bottom, and the spring leaf rubber sleeve is placed between union and tube connector two boss.Endoporus has tapering, the tensioner cover 3 that lower port has ten gap 9 is placed in the outside that lower pipe connection 6 is connected with the tube connector lower end, locking card 4 is stuck on the torsional stop 7 that is arranged on pair of pipes joint, the tube connector, so that when pipeline rotated, last union, lower pipe connection, tube connector did not relatively rotate.A stay cord 10 is equipped with in locking card upper end.
During use, put into gas in mine automatic sealing device under the coal mine that needs shutoff, gas tubes such as oil gas field, natural gas, spur wire rope again, the locking clamp comes off.Rotate pipeline, last union, lower pipe connection, tube connector relatively rotate, and screw thread screws, union, tube connector 6 pillow block extrusion spring sheet rubber sleeves on this moment, and spring leaf rubber sleeve spreading, contact surface can reach 200mm behind the spreading, effectively stops gas communication; Tensioner is enclosed within lower pipe connection extruding spreading down simultaneously, plays from solid effect, promptly finishes shutoff.
Claims (4)
1. gas in mine automatic sealing device, comprise pair of pipes joint, tube connector, spring leaf rubber sleeve, tensioner cover and locking card, it is characterized in that: the pair of pipes joint is connected with the tube connector two ends respectively, the spring leaf rubber sleeve is placed in the outside that union is connected with the tube connector upper end, the tensioner cover is placed in the outside that lower pipe connection is connected with the tube connector lower end, and locking is stuck on the torsional stop that is arranged on pair of pipes joint, the tube connector.
2. gas in mine automatic sealing device according to claim 1, it is characterized in that: the described union top of going up is provided with a boss, one boss is arranged at the tube connector bottom, and the spring leaf rubber sleeve that interior periphery is embedded with spring leaf is placed between union and tube connector two boss.
