Abstract
The utility model belongs to a buried spring support gate valve, wherein an extension rod is arranged between the upper end of valve rod and the lower end of open handle and is arranged in an extension outer sheath, while the extension rod and extension outer sheath are coupled through bearing and the upper end of valve rod is connected with the lower end of open handle; the lower end of the extension rod is connected with the upper end of the valve rod through a splicing north and the periphery of the upper end of the extension outer sheath is positioned in a valve pit, while the upper end of the valve pit is provided with a valve pit cover that is coupled with a valve pit wall through a cap shaft and a valve cover lock is arranged on the valve pit cover. The utility model applies the design proposal by extending the valve rod so as to deeply bury the valve and pipeline, reduce the dimension and manufacture cost of valve pit, facilitate operating the valve and have the advantages of preventing from theft and beautifying the road environment.
Description
Technical field
The utility model belongs to a kind of direct built-in elastic sluice valve with wedge-shaped sealing face.
Background technique
Various valves such as the gate valve that uses on the present pipeline, stop valve, ball valve are born the effect that pipeline was blocked and regulated in its sealing, and all buried usually underground about 2～10 meters of pipeline, valvular position is equipped with valve pit usually and communicates with ground in pipeline, in order to operated valve, when needing operated valve, operator must descend to the down-hole, make troubles to operation, the existence of pipeline valve pit has simultaneously strengthened difficulty of construction and cost, also cheats theft valve and pipeline goods and materials and provides convenience.
Summary of the invention
The purpose of this utility model provides a kind of direct built-in elastic sluice valve with wedge-shaped sealing face, adopt to prolong the design proposal of valve rod, and valve and pipeline with buried, dwindled and reduce valve pit size and cost, and the easy-to-operat valve has antitheft and advantage that beautify road environment.For this reason, the utility model adopts between valve rod upper end and the opening handle lower end and is provided with extension rod, extension rod is arranged in and prolongs overcoat, be coupling by bearing between extension rod and the prolongation overcoat, the upper end of extension rod connects the opening handle lower end, and the lower end of extension rod connects the valve rod upper end by the grafting notch, prolong outer set upper side periphery and be arranged in valve pit, the valve pit lid is established in the valve pit upper end, and the valve pit lid is coupling with the valve pit wall by the lid axle, and valve pit covers establishes the valve gap lock.The said structure design has realized the purpose of this utility model.
Advantage of the present utility model with buried, is dwindled valve and pipeline to have reduced valve pit size and cost, and the valve pit degree of depth dwindles 90%, and the valve pit width dimensions dwindles 70%, and the valve pit cost reduces by 85%.Operator can directly open valve pit on ground and operate, and operated valve is convenient, laborsaving.Also have antitheft and beautify road environment, easy to maintenance, anti-spreading, the advantage of avoiding well lid to lose.
Description of drawings
Figure is a structural representation of the present utility model
Embodiment
As shown in the figure, a kind of direct built-in elastic sluice valve with wedge-shaped sealing face is made up of valve pit 12, valve seat 6, valve rod 8 and valve body 7.Be provided with extension rod 11,110 between valve rod upper end and opening handle 3 lower ends, extension rod is arranged in and prolongs overcoat 10, is coupling by bearing 4,15 between extension rod and the prolongation overcoat, so that extension rod can rotate in prolonging overcoat.The upper end of extension rod connects the opening handle lower end, and opening handle can be traditional annular hand grip or square handle.The lower end of extension rod connects the valve rod upper end by grafting notch 9, grafting notch internal orifice shape should be corresponding with connection valve rod upper end shape, but all should be angular shape, as square, triangle, Hexagon etc., so that driving valve rod, the grafting notch that fuses with the extension rod lower end rotates, with opening/shutting valve.
Prolong outer set upper side periphery and be arranged in valve pit, all the other bottoms all use soil buried in underground together with valve, valve pit lid 1 is established in the valve pit upper end, the valve pit lid is coupling with valve pit wall 16 by lid axle 2, draw rotating valve well lid then like this, the open valve well lid simultaneously also can prevent that the valve pit lid from taking from the valve pit wall easily, prevents that it from losing.For preventing other people dig a well without authorization valve pit lid, valve pit covers establishes valve gap lock 13, and with the locking valve well lid, the structure of valve gap lock is a conventional construction.
Described extension rod can be pegged graft by two elongated segment bars and is linked to be.Obviously, when surpassing extension rod and prolonging the length of overcoat as if the distance on opening handle and the valve rod, available two extension rods and two extension rod overcoats grafting reach suitable length with prolongation.As shown in the figure, extension rod 110 lower ends and extension rod 11 upper ends and two prolong the joint 14 that forms between the overcoat, the corresponding connecting means that the joint of two elongated segment bars and two prolongs the joint between the overcoats are traditional connecting means, as welding, be spirally connected etc., so be not repeated.
Described prolongation overcoat lower end is affixed with corresponding valve body, as the welding etc.
The valve that the utility model is suitable for various control valve pipelines 5 uses, and during use, opens the valve pit lid, rotate opening handle, opening handle drives extension rod and rotates in prolonging overcoat, and grafting notch in extension rod lower end drives valve rod and rotates, open and close valve seat, the opening/shutting valve pipeline.
In a word, the utility model has valve and pipeline with buried, and dwindle and reduced valve pit size and cost, The valve pit degree of depth dwindles 90%, and the valve pit width dimensions dwindles 70%, and the valve pit cost reduces by 85%. Operating personnel can directly exist Ground is opened valve pit and is operated, and operated valve is convenient, laborsaving. Also have antitheft and beautify road environment, dimension Repair conveniently anti-spreading, the advantage of avoiding well lid to lose.
