Abstract
The utility model relates to a butt clamped expansion water flow stop used for blocking a pipeline, which is composed of a water closing conic table, a stop conic table, a rubber water closing ring, a bolt, and a nut, wherein, the axis of the water closing conic table is drilled and is threaded, the axis of the stop conic table is perforated, the head end of the bolt and the water closing conic table are in screw connection, the tail end passes through the stop conic table and is matched with the nut, and the rubber water closing ring is butted and clamped between the two conic tables. The utility model has the advantages of convenient operation, simple structure, and tight water closure.
Description
The utility model relates to a kind of butt clamped expansion water flow stop that is used for bolt plugging road.
In the construction of construction engineering sewerage system, the instrument in bolt plugging road is absolutely necessary.Usually adopt the plug mud drum in the prior art, beat methods such as timber is stifled, rubber pneumatic bag.The plug mud drum, to beat the stifled workload of timber big, mounting or dismounting inconvenience, and waste material, and rubber pneumatic bag more need be equipped with pump, and the damage cost of use is also higher because rubber pneumatic bag easily leaks gas.
The purpose of this utility model provides a kind of simple in structure, and it is tight to close water, butt clamped expansion water flow stop easy to loading and unloading.
In order to achieve the above object, the utility model closes water ring, bolt and nut and forms by closing water frustum, stop frustum, rubber, close water frustum axle center drilling and tapping, the perforation of stop frustum axle center, the bolt head end with close the water frustum and be threaded, tail end passes the stop frustum and cooperates with nut, in the middle of two frustums folder rubber is closed water ring.
Below in conjunction with specific embodiment technical characteristics of the present utility model is described in further detail.
Fig. 1 is the sectional view of the utility model butt clamped expansion water flow stop.
With reference to figure 1, the utility model butt clamped expansion water flow stop closes water frustum (3) by control breathing, the stop frustum (6) of control friction, and rubber-like rubber closes water ring (4), and bolt (5) and nut (8) are formed.Close water frustum (3) axle center drilling and tapping, the perforation of stop frustum (6) axle center, bolt (5) head end with close water frustum (3) and be threaded, tail end passes stop frustum (6) and cooperates with nut (8), in the middle of two frustums folder rubber is closed water ring (4), bolt (5) head and closing uses filler (2) sealing between the water frustum (3), use packing ring (7) fastening between nut (8) and the stop frustum (6), bolt (5) afterbody is provided with anti-rotation cushion cap (9), anti-rotation cushion cap (9) have two single file planes or with bolt axis to vertical anti-rotation jack.
During use, the butt clamped expansion water flow stop that is in loosening state fully is placed on installation to finish and waits in the hidden tube chamber (1), the butt clamped expansion water flow stop close water frustum (3) one ends towards closing water piping system, stop frustum (6) one ends are towards the sluicing mouth of pipe, and make stop frustum (6) and close water pipe and hold level with both hands together, slightly firmly clockwise direction turns the nut (8) on the bolt (5), for preventing that bolt (5) from rotating with nut (8), use the another spanner to block anti-rotation cushion cap (9) counterclockwise, or use inserted link to insert the anti-rotation jack, when closing water frustum (3), stop frustum (6) and rubber close water ring (4) and are in when being with the power state slightly, ajust intraluminal butt clamped expansion water flow stop, continue to turn nut (8) then, make and close water frustum (3) and stop frustum (6) and draw close mutually, force rubber to close water ring (4) and compress also expansion towards periphery vertically, up to being crowded with the two frustum conical surface and luminal spaces, because rubber closes the expansion of water ring (4) and has blocked the space of crossing water, closes the tight purpose of water thereby reach.Again because rubber closes frictional force that the expansion of water ring (4) produces greater than the hydrostatic pressure in the tube chamber (1), thereby guaranteed the fixing of butt clamped expansion water flow stop position.Finish using, can make after water slowly releases in the pipe, take out the butt clamped expansion water flow stop, finish the use overall process of butt clamped expansion water flow stop by loose nut (8).
This butt clamped expansion water flow stop is very easy to use, and simple in structure, and it is tight to close water, is that pipeline closes tool on the first-selection of water.
Claims (1)
1, a kind of butt clamped expansion water flow stop, it is characterized in that closing water ring, bolt and nut and forming by closing water frustum, stop frustum, rubber, close water frustum axle center drilling and tapping, the perforation of stop frustum axle center, the bolt head end with close the water frustum and be threaded, tail end passes the stop frustum and cooperates with nut, in the middle of two frustums folder rubber is closed water ring.
