Abstract
The utility model discloses an antibiotic stop valve. The antibiotic stop valve comprises a valve body, a valve clack, a valve rod, a valve deck, and a hand wheel. A resilient pad is padded between the valve body and the valve deck. The valve rod and the valve clack are fixedly connected through a valve clack nut. The valve clack is an exhaust valve clack having an exhaust slot. The bottom part of the valve clack is equipped with a sealing ring and a pad pressing plate. The sealing ring, the pad pressing plate, and the valve clack are fixed through a hexagon nut, a spring pad, and a flat washer. The valve rod is sleeved with a valve rod nut. The valve rod nut and the valve deck are fixed through a fastening screw. The top part of the valve rod is provided with the hand wheel. The hand wheel and the valve rod are fixedly connected through another flat washer and another hexagon nut. An upper cover is provided with a packing gland. The packing gland is internally provided with packing. The packing gland and the valve deck are fixedly connected through a split pin, a pin shaft, and an eyelet bolt. The valve body is internally provided with an arc-shaped channel. The valve rod is a screw threaded rod. The beneficial effects of the utility model are that the bottom part of the valve rod is fixedly connected with the valve clack through the valve clack nut so that the working stroke of the valve clack is greatly shortened and the opening and closing time is reduced.
Description
Technical field
The utility model relates to a kind of stop valve, relates in particular to a kind of antibiotic stop valve.
Background technique
The kind of stop valve is divided by the position of threaded stem external thread type, I.S.S; By the flow direction of medium, divide have straight-through type, direct current type and angie type (Three way type).The open-shut device of known stop valve (stop valve, Globe Valve) is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of fluid.The fully open position of stop valve and contract fully, should be decided by the stroke of flap, yet existing stop valve stroke is large, makes time of closing and opening long; Tradition break valve cover and valve seal poor performance, be easy to like this waste resource, and working life is shorter, has increased cost; Common stop valve dismounting is not easy, and has increased the difficulty of maintenance, can not be anticorrosion, on flap, there is no exhaust port.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of antibiotic stop valve.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of antibiotic stop valve, comprise valve body, flap, valve rod, valve gap and handwheel, between valve body and valve gap, be lined with a resilient pad, valve rod is fixedly connected with by flap nut with flap, flap is the exhaust flap with air vent, flap bottom is provided with seal ring and pad pressing plate, and seal ring, pad pressing plate and flap are fixed by the first hexagon nut, spring pad, plain washer; On valve rod, cover has a Stem Mut, and Stem Mut and valve gap are fixed by Cock screw; Valve rod top is provided with handwheel, handwheel is fixedly connected with by plain washer, the second hexagon nut with valve rod, on cover and be provided with Gland, in Gland, be provided with filler, Gland is fixedly connected with by cotter pin, bearing pin, swing bolt with valve gap, in valve body, be provided with the passage of arc, valve rod is threaded screw rod.
Described valve body and valve gap are fixed by stud, the 3rd hexagon nut.
On described swing bolt, cover has plain washer and the 4th hexagon nut.
On flap, be coated with anticorrosive PTFE layer.
Valve body bottom is provided with outfall.
On handwheel, be evenly equipped with pit.
Cotter pin is U-shaped.
The beneficial effects of the utility model: this model utility is fixedly connected with flap in the bottom of valve rod by flap nut, has greatly reduced the working stroke of flap, have reduced the time of entirely opening and closing of valve; Valve body is to be all connected with screw fastening by bolt with valve gap, valve rod and handwheel, and between be lined with pad, make easy removal, more easily maintenance, reduced cost; Seal ring is installed in valve body, has improved sealability, reduced energy consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of antibiotic stop valve, comprise valve body 1, flap 7, valve rod 9, valve gap 13 and handwheel 23, between valve body 1 and valve gap 13, be lined with a resilient pad 10, valve rod 9 is fixedly connected with by flap nut 8 with flap 7, and flap is the exhaust flap with air vent, when closing, tightr, flap 7 bottoms are provided with seal ring 6 and pad pressing plate 5, and seal ring 6, pad pressing plate 5 and flap are fixed by the first hexagon nut 2, spring pad, plain washer; On valve rod 9, cover has a Stem Mut 21, and Stem Mut 21 and valve gap 13 are fixing by Cock screw 22; Valve rod 9 tops are provided with handwheel 23, handwheel 23 is fixedly connected with by plain washer, the second hexagon nut 25 with valve rod 9, on cover and be provided with Gland, in Gland, be provided with filler 14, Gland is fixedly connected with by cotter pin, bearing pin 17, swing bolt 18 with valve gap 13, in valve body 1, be provided with the passage of arc, valve rod is threaded screw rod, rises so more steady.Described valve body 1 and valve gap 13 are fixing by stud 11, the 3rd hexagon nut 12.On described swing bolt 18, cover has plain washer and the 4th hexagon nut 20.On flap 7, be coated with anticorrosive PTFE layer, can be anticorrosion.Valve body 1 bottom is provided with outfall, can drain impurity etc.On handwheel 23, be evenly equipped with pit, conveniently hold.Cotter pin is U-shaped, fixes so more convenient.Handwheel 23 outer surfaces are provided with nameplate.During use, user is only with the handwheel 23 that turns clockwise, handwheel 23 will be with ovable valve stem 9 rotations, valve rod 9 will move upward with the flap 7 of ovable valve stem 9 bottoms, reach the valve body of unlatching, when needs valve body, only with being rotated counterclockwise handwheel 23, flap 7 will, along with the moving downward of valve rod 9, reach the object of valve body.The beneficial effects of the utility model: this model utility is fixedly connected with flap in the bottom of valve rod by flap nut, has greatly reduced the working stroke of flap, have reduced the time of entirely opening and closing of valve; Valve body is to be all connected with screw fastening by bolt with valve gap, valve rod and handwheel, and between be lined with pad, make easy removal, more easily maintenance, reduced cost; Seal ring is installed in valve body, has improved sealability, reduced energy consumption.
