The purpose of this utility model is just to provide to solve the problem the bottom valve that a kind of operation stability is higher.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of bottom valve, comprise valve seat, first vertical masonry joint pipe crimping, second vertical masonry joint pipe crimping, 3rd vertical masonry joint pipe crimping, valve rod and the valve block be enclosed within described valve rod, the first guide ring is provided with in described first vertical masonry joint pipe crimping, described first vertical masonry joint pipe crimping is fixedly connected on the left part of described valve seat, described 3rd vertical masonry joint pipe crimping is arranged on the sidewall of described second vertical masonry joint pipe crimping, the right part of described valve seat is connected with the 4th vertical masonry joint pipe crimping by the first reducer fitting, described second vertical masonry joint pipe crimping is connected with the 5th vertical masonry joint pipe crimping by the second reducer fitting, described 4th vertical masonry joint pipe crimping docks with described 5th vertical masonry joint pipe crimping, the second guide ring is provided with in described 5th vertical masonry joint pipe crimping, one end of described valve rod is arranged in described first guide ring, the other end is arranged in described second guide ring, described valve block is between described valve seat and described second guide ring.
Further, described 3rd vertical masonry joint pipe crimping is mutually vertical with described second vertical masonry joint pipe crimping.
Further, one end of described second vertical masonry joint pipe crimping is connected with described 5th vertical masonry joint pipe crimping by described second reducer fitting, and the other end is provided with the top board of band stiffening rib.
Further, described 4th vertical masonry joint pipe crimping is fixedly docked by welded flange with described 5th vertical masonry joint pipe crimping.
Further, described 4th vertical masonry joint pipe crimping is consistent with the size specification of described 5th vertical masonry joint pipe crimping.
Further, described first reducer fitting and described second reducer fitting are taper joint pipe.
The beneficial effects of the utility model are:
The utility model is by valve block design in water-dilution channel, and when clear water refluxes, momentum effect, at valve block upper surface, adds Action of Gravity Field, makes it following current and returns seat in time, stops time delay and stuck phenomenon; Shorten shaft length, reduce the stroke of valve block, reduce its eccentric stuck probability in running; Profile is less, reduces Flange joint, reduces and reveals probability, installation difficulty and manufacture cost, be more suitable for installing under water.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises valve seat 3, first vertical masonry joint pipe crimping 2, second vertical masonry joint pipe crimping 9, 3rd vertical masonry joint pipe crimping 12, valve rod 15 and the valve block 13 be enclosed within valve rod 15, the first guide ring 1 is provided with in first vertical masonry joint pipe crimping 2, first vertical masonry joint pipe crimping 2 is fixedly connected on the left part of valve seat 3, 3rd vertical masonry joint pipe crimping 12 is arranged on the sidewall of the second vertical masonry joint pipe crimping 9, the right part of valve seat 3 is connected with the 4th vertical masonry joint pipe crimping 5 by the first reducer fitting 4, second vertical masonry joint pipe crimping 9 is connected with the 5th vertical masonry joint pipe crimping 16 by the second reducer fitting 8, 4th vertical masonry joint pipe crimping 5 docks with the 5th vertical masonry joint pipe crimping 16, the second guide ring 7 is provided with in 5th vertical masonry joint pipe crimping 16, one end of valve rod 15 is arranged in the first guide ring 1, the other end is arranged in the second guide ring 7, valve block 13 is between valve seat 3 and the second guide ring 7.
In the present embodiment, the 3rd vertical masonry joint pipe crimping 12 is mutually vertical with the second vertical masonry joint pipe crimping 9, is convenient to welding.One end of second vertical masonry joint pipe crimping 9 is connected with the 5th vertical masonry joint pipe crimping 16 by the second reducer fitting 8, and the other end is provided with the top board 10 of band stiffening rib 11, makes total more stable, reliably.4th vertical masonry joint pipe crimping 5 is fixedly docked by welded flange 6 with the 5th vertical masonry joint pipe crimping 16, and docking structure is simple.4th vertical masonry joint pipe crimping 5 is consistent with the size specification of the 5th vertical masonry joint pipe crimping 16, to guarantee seamless docking.First reducer fitting 4 and the second reducer fitting 8 are taper joint pipe, thus can be docked and connected between the pipe crimping that can realize different-diameter.
Bottom valve described in the utility model, the distance a shown in figure is the range of valve block 13 along valve rod 15.In original technology, valve block 13 is only subject to Action of Gravity Field, if valve rod 15 is eccentric or card, valve block 13 can not return seat in time, and in runner of the present utility model, and valve block 13 is that seat is returned in fluid impulse force and gravity double-action when being subject to refluxing, valve can not be in long term open state, there will not be the situation blocking valve block 13, the stroke of valve rod 15 and valve block 13 shortens, and is not easy to break down in frequent movement process; In original bottom valve structure, tie point is many, and the adpting flange of setting has six, install with maintenance difficulty large, easily leak, and only have two welded flanges 6 in the utility model for connecting, manufacture cost is lower, installs with maintenance difficulty little, is not easy to leak.
