Abstract
The utility model discloses a hand-operated quick opening and closing gate valve. The gate valve comprises a valve body, a gate plate arranged in the valve body, and a valve rod connected with the gate plate. The upper end of the valve body is provided with valve deck. The valve rod penetrates through the valve deck to be connected with T-shaped screw threads of the gate plate. A sealing structure is arranged in the place between the upper end of the gate plate and the valve body. Packing is arranged between the upper part of the valve deck and the valve rod. A packing gland is arranged on the packing. The packing gland and the valve deck are fixedly connected through a cotter pin and a hexagonal nut. The top end of the valve rod is connected with a hand wheel. The beneficial effects of the utility model reside in that the gate valve is simple in production technology and convenient to assemble; as the T-shape screw thread segment of the valve rod shortens half of the stroke, the corresponding valve deck support structure is also shortened in the same ratio so that the hand-operated opening and closing are quick, the cost of the gate valve is reduced, and the gate valve is compacter in structure and more convenient to use; and a traditional sealing structure on the valve rod is changed into a sealing structure on the gate plate, so that the sealing performance is good, the service life is long, and the stability is good.
Description
Technical field
The utility model relates to a kind of pipeline field, particularly a kind of manual fast opening and closing gate valve.
Background technique
In pipeline neighborhood system, the application of gate valve is more extensive, the feature of the open-shut device of traditional gate valve, basic for valve rod and nut turn realize keying, its valve rod and nut turn are one end stroke open-close on-off, and rotating distance is long, keying speed is slow, and sealing is good not.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of manual fast opening and closing gate valve is provided.
To achieve these goals, the measure that the utility model is taked:
A kind of manual fast opening and closing gate valve, comprise valve body, the valve rod of being located at the flashboard in valve body and being connected with flashboard, described valve body upper end close-fitting has valve gap, valve rod is threaded with flashboard through valve gap, described flashboard upper end and the position between valve body are provided with sealing configuration, between valve gap top and valve rod, be provided with filler, filler top is provided with Gland, between Gland 7 and valve gap, by cotter pin, be fixedly connected with hexagon nut, described valve stem tip is connected with handwheel, flashboard is hollow-core construction, the inner side edge of the joint of valve body and valve gap is along being provided with groove, in groove, be placed with lubricant oil, the through hole inside edge of passing for valve rod on valve gap is provided with the seal ring of horizontal strip.
Flashboard is wedge shape.
The top of described valve gap is provided with handle.
Handwheel is provided with hook, is also provided with hook on valve body, by two locked by hooks valves.
Valve rod is connected with electric actuator by driving mechanism, and electric actuator is electrically connected to wireless controller.
The beneficial effects of the utility model: the utility model production technology is simple, easy to assembly, because the T-shaped thread section of valve rod shortens two/one stroke, corresponding valve gap supporting structure also shortens on year-on-year basis, manual opening-closing speed is fast, reduced cost, more compact structure, it is more convenient to use, change sealing configuration on traditional valve rod on flashboard sealing configuration, good seal performance, long service life, good stability.
Accompanying drawing explanation
The structural representation of Fig. 1, the utility model structure.
Embodiment
A kind of manual fast opening and closing gate valve as shown in Figure 1, comprise valve body 1, the valve rod 4 of being located at the flashboard 5 in valve body 1 and being connected with flashboard 5, described valve body 1 upper end is connected with valve gap 2, valve rod 4 is threaded with the T-shaped of flashboard 5 through valve gap 2, the described T-shaped worm structure of valve rod 4 hypomere is for shortening 1/2nd spiral stroke structure, this structure opening speed is fast, materials'use is few, more compact structure, described flashboard 5 upper ends and the position between valve body 1 are provided with sealing configuration, good airproof performance, between valve gap 2 tops and valve rod, be provided with filler 6, filler 6 tops are provided with Gland 7, between Gland 7 and valve gap 2, by cotter pin 8, be fixedly connected with hexagon nut 9, described valve rod 4 tops are connected with handwheel 3, it is convenient to open, the top of described valve gap 2 is provided with handle 10, the gate valve of conveniently taking.
