Abstract
The fast valve specially for fire fighting includes one right valve body, one left valve body, one valve seat inside the valve bodies, one valve plate matching the valve seat and one handle connected to the valve plate. The valve seat and the valve plate are set radically inside the valve bodies and fitted mutually via plates, and have through holes corresponding to each other. Normally, water flows through the through holes, and shifting the valve plate to stagger the through hole in the valve seat and that in the valve plate can cut off water flow. The shift stroke of the valve plate is equal to the diameter of hole or only 20-25 % shift stroke of common gate valve, so that the valve has fast operation. In addition, the valve may be operated conveniently through one long tool.
Description
Technical field
The present invention relates to a kind of valve, relate generally to a kind of immediate action valve of fire-fighting special use.
Background technique
The valve of installing in fire hydrant the place ahead is generally normally open, to guarantee that fire hydrant has water at any time.But when fire hydrant goes wrong, require this valve to close rapidly, block current, to shorten the repair time to greatest extent.At present, the valve that uses at this position often adopts hand sluice valve or butterfly valve, and its working principle is by the handwheel rotary screw valve plate to be moved, and often need rotate a few and valve plate could be moved a bit, so closing valve time is longer.In addition, because valve generally is installed in 2～3 meters dark valve wells, cause valve often not had by water logging, during closing valve, operator need dress under the rainwear and carry out underwater operation in valve well, and are very inconvenient, bother equally in the time of need opening again.
Summary of the invention
The purpose of this invention is to provide a kind of energy fast shut-off or connect fire hydrant special valve current, easy and simple to handle.
For reaching above-mentioned purpose, the technical solution used in the present invention is: this fast valve specially for fire flighting comprises left and right valve body, be arranged on valve seat in the valve body, the valve plate that matches with valve seat and the handle that is connected with valve plate, valve seat and valve plate are respectively and radially are arranged on flat board in the valve body, that work in coordination in its surface, are respectively arranged with at least one through hole in correspondence with each other on valve seat and valve plate.
Described valve seat is two flat boards, and radial symmetric is arranged on the inner chamber of left and right valve body respectively, and the surface of valve plate both sides is slidingly matched with the surface of two valve seats respectively, upper end at valve plate is provided with valve shaft, valve shaft is provided with tooth bar, and handle is provided with gear, and wheel and rack is meshed.
Valve plate is connected by pin with valve shaft, two valve seats respectively by dowel fixes on left and right valve body; Described be separately positioned on valve seat and the valve plate and through hole in correspondence with each other is 20, all through holes are regularly to be arranged, in the distance between every edge, adjacent two hole on the movement direction more than or equal to the diameter of through hole.
Valve body is provided with valve gap, and valve shaft is contained in the valve gap inner chamber, and valve gap is provided with gland, is provided with handle shaft in gland, and handle is fixed on the overhanging end of handle shaft, and gear is fixed on the handle shaft and is meshed with tooth bar on the valve shaft.
Both sides up and down at gland also are respectively arranged with limiting board, and limiting board is provided with stop nut, and the bottom end of stop nut contacts with handle.
Handle is connected with the handle shaft axle head by square opening, and by pad and screw on gland; On handle shaft, also be provided with seal ring; Be connected by screw respectively between the left and right valve body, between valve body and the valve gap and between valve gap and the gland.
Because valve seat and valve plate are set to the flat board of working in coordination in its plane, flat board is provided with a plurality of through holes in correspondence with each other, and water can be flowed out by through hole during normal state, when needing to cut off current, only need mobile valve plate, lead to the hole site on valve seat and the valve plate is staggered mutually fully get final product.Move valve plate by gear, rack structure, can shorten the operating time; Can guarantee in the shortest shift motion, to make the through hole of valve plate and valve seat to stagger fully or in correspondence with each other at the position-limit mechanism that is provided with on the valve body.Because the shift motion of valve plate is equivalent to the aperture of its through hole, make the valve plate stroke only be 20%25% of conventional gate valve, so the operation of this valve of switch is quick, easy.In addition, also can use the lengthening instrument to carry out the push-and-pull operation, thereby save the trouble that personnel go into the well.

Embodiment
Valve plate 2 that this fast valve specially for fire flighting comprises left valve barrel 1, right valve barrel 14, be arranged on valve seat 4 in the valve body, match with valve seat and the handle 10 that is connected with valve plate.In the present embodiment, described valve seat 4 is two flat boards of being made by stainless steel, and radial symmetric is arranged on the inner chamber of left and right valve body respectively, and two valve seats 4 are fixed on the left and right valve body by pin 5 respectively.Valve plate 2 is for being clipped in the flat board that two stainless steels between the valve seat are made, and the surface of valve plate 2 both sides is slidingly matched with the surface of two valve seats 4 respectively.On valve seat 4 and valve plate 2, be respectively arranged with at least one through hole 3 in correspondence with each other, in the present embodiment, described through hole is 20, all through holes are regularly to be arranged, can make the through hole complete closed for after moving at valve plate, in the distance between every edge, adjacent two hole on the movement direction more than or equal to the diameter of through hole.In addition, also can through hole be set to be less than or, get final product because the shift motion of valve plate only is equivalent to the aperture of its through hole, so the speed of switch valve can be accelerated in the small aperture more than 20.In addition, also can be staggered in the position, the left and right sides of the through hole of two rows, this moment is as long as the adjacent edge in every horizontal two holes apart from more than or equal to the aperture, can shorten the shift motion of valve plate 2 too.Be provided with pin-and-hole 20 in the lower end of valve shaft 7, valve plate 2 is connected with valve shaft 7 with pin-and-hole 20 by two pins 6.Be provided with tooth bar 19 on valve shaft 7 tops, handle 10 is provided with gear 16, and gear 16 is meshed with tooth bar 19.
Upper-end surface at two valve bodies also is provided with valve gap 9, valve gap 9 is housings, valve shaft 7 is contained in the inner chamber of valve gap 9, valve gap 9 is provided with gland 8, in gland 8, be provided with handle shaft 17, handle 10 is fixed on the overhanging end of handle shaft 17, and gear 16 is fixed on the handle shaft 17 and is meshed with tooth bar 19 on the valve shaft 7.In the present embodiment, handle 10 is connected by the square shaft of square opening with the handle shaft axle head, and is fixed on the handle shaft 17 by pad 11 and bolt 15.In addition, also can connect by alternate manners such as key or screws.For waterproof, on handle shaft 17, also be provided with seal ring 18.
In order to make valve can reach accurate position rapidly when the switch, also be respectively arranged with limiting board 13 on the both sides up and down of gland 9, limiting board 13 is provided with the stop nut 12 of adjustable length, and the bottom end of stop nut 12 can contact with handle 10.
