Abstract
The utility model relates to a water block of pipe. The water block of pipe comprises a gasbag, a gasket, an air valve and a nut. One end of the gasbag is blocked, and the other end is installed with the air valve which is glued with the gasbag. The utility model is characterized in that the inner wall at one end of gasbag is installed with a gasket. The air valve can be blocked. The air valve does not break off in inflation. The service lifetime of water block is prolonged. The gasbag has the advantages of smooth transition, no dead space, strong compression resistance and no easy cracking after pressurizing and inflation. The gasbag is installed with a reinforcing band for increasing the compressive strength of gasbag. The water block is installed with a novel gasket with good sealing property and the gas is not easily leaked after inflation. The specification sizes are serialized. The water block of pipe is easily jointed with the inner wall of pipe and can be widely used for blocking water and realizing pipe blocking of pipes of domestic water pipe, fire-demand water pipe, draining pipe, sewage pipe, etc. in pressure testing, water closing experiment, maintenance or desilting operation. The water block of pipe can be also used for blocking air pipe in emergency dealing of gas pipe and thermal pipe.
Description
Technical field
The utility model belongs to, drainage pipe construction tool, relates to a kind of pipeline water flow stop.
Background technique
Give, in the drainage pipe construction operation, usually to block current, realize blocking pipe, now widely used is the rubber pneumatic bag water flow stop, plugging effect is pretty good, but also exist some shortcomings: because ubiquity dead angle, air sac two ends, the position, dead angle is easy to ftracture when the pressurization inflation; Because the general wall thickness of air sac of blow molding is thinner, blasting phenomena can occur during pressurization; Because valve cock position design is unreasonable, when inflating valve cock through regular meeting because of gas pressure cause greatly bang go out to come off to make the water flow stop newspaper to decrease; Because the poor sealing at valve cock position has leakage during gas.
Summary of the invention
The purpose of this utility model is to provide a kind of compression resistance strong, valve cock difficult drop-off, the pipeline water flow stop of good airproof performance.
The technical solution adopted in the utility model: a kind of pipeline water flow stop, comprise air sac, packing ring, valve cock, nut, an end back cover of its air sac, the other end is provided with valve cock, valve cock and air sac are glued together, and described air sac one end inwall is provided with liner.
Described valve cock outer end is provided with sealed cap, sealing cover, the outer nut that is spirally connected, and the air sac inner chamber is stretched in the inner, passes liner, is provided with packing ring, and inner nut is spirally connected.
The one side that described packing ring contacts with liner is an arc, and the one side that contacts with inner nut is the plane.
Described liner diameter is equivalent to the 1/2-1/3 of air sac diameter.
Described liner is with the arc surface parcel of air sac one end.
Described air sac outer surface is provided with cross or spirality reinforcing strip.
Described air sac intermediate section is a cylindrical shape, and two ends are circular arc.
Described air sac is cylindrical, tubular, sphere, cydariform, Pear Shaped, vase-shaped, each position rounding off, no dead angle.
The positive beneficial effect that the utility model had:
1. the air sac two ends are rounding off, no dead angle, and compression resistance is strong, and is not easy to crack after the pressurization inflation;
2. air sac is provided with reinforcing strip, improves the compressive strength of air sac, avoids the air sac explosion;
3. be provided with liner in the air sac, can stop valve cock, make when inflating the valve cock can bang falling out, the working life of improving water flow stop;
4. be provided with the novel seal pad, good airproof performance, inflation back gas is difficult for revealing;
5. specification seriation is easy to fit with inner-walls of duct, can be widely used in pressure testings such as domestic water pipeline, fire-fighting water pipeline, drainage pipeline, sewage conduct, block current when closing water experiment, maintenance or dredging operation, realizes blocking pipe; Also can be used for coal gas, the shutoff airflow line used when heat distribution pipeline was speedily carried out rescue work operation.
