Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a natural gas valve capable of being replaced under pressure, which includes a valve 1, a nut 2, a first pipeline 3, a screw rod 4, a sealing ring 5, a fixing block 6, a spring 7, a natural gas channel 8, a supporting plate 9, a connecting barrel 10, a second pipeline 11, a sliding block 12, a fixing rod 13, a U-shaped groove 14, a fixing iron block 15, a bolt 16 and a rotating shaft 17.

One side welding of valve 1 has screw rod 4, the internally mounted of screw rod 4 has first pipeline 3, the outer wall connection of screw rod 4 has nut 2, the welding of one side of first pipeline 3 has natural gas channel 8, the outer wall connection of first pipeline 3 has sealing washer 5, the outer wall connection of sealing washer 5 has fixed block 6, spring 7 is installed to one side of fixed block 6, one side of spring 7 is connected with backup pad 9, one side of screw rod 4 is connected with connecting bucket 10, the internally mounted of connecting bucket 10 has second pipeline 11, the outer wall welding of nut 2 has fixed iron plate 15, the mid-mounting of fixed iron plate 15 has pivot 17, the outer wall connection of pivot 17 has dead lever 13, one side of dead lever 13 is connected with slider 12, one side threaded connection of slider 12 has bolt 16, one side of slider 12 is connected with U type.

Be swing joint between nut 2 and the screw rod 4, be fixed connection between screw rod 4 and the first pipeline 3, rotate nut 2 at screw rod 4 for both keep away from the motion each other, make nut 2 and screw rod 4 separation, but so quick replacement natural gas valve.

The backup pad 9 passes through spring 7 and fixed block 6 constitution active structure, and the width of backup pad 9 is greater than the width of first pipeline 3, and backup pad 9 covers on sealing washer 5 under the effect of spring 7 for when dismantling, prevent that the natural gas from leaking, cause danger.

Be fixed connection between first pipeline 3 and the natural gas passageway 8, natural gas passageway 8 is the dense poroid, and natural gas passageway 8 is the dense poroid, so natural gas accessible natural gas passageway 8 enters into in the first pipeline 3.

The fixing rod 13 and the U-shaped groove 14 form a movable structure through the sliding block 12, and the U-shaped groove 14 is annular, so that the fixing rod 13 slides on the U-shaped groove 14 through the sliding block 12, and the connecting barrel 10 is fixed when the nut 2 is fixed in a rotating mode.
