The leakage blocking cover plate with pressure comprises a leakage blocking cover plate, a ball valve, a drainage tube and a quick-mounting press plate; the quick-mounting press plate is sleeved and covered on the leakage blocking cover plate; the ball valve is in spiral connection with a drainage through hole on the leakage blocking cover plate; the drainage tube is connected with the ball valve; and the quick-mounting press plate is provided with a device for fixing the quick-mounting press plate on the steel pipeline. The utility model has the following advantages: 1, the mounting is convenient and quick and the labor intensity is low; 2, the overflow through diameter is large, the pressure in a cavity is low and the welding construction on the outer edge of the cover plate is facilitated; and 3, the sealing effect is good and the performance is safe and reliable.

Description

Steel pipe pressure sealing cover plate
Technical field: the utility model relates to the utensil of using, particularly a kind of steel pipe pressure sealing cover plate in safeguarding repairing steel conveyance conduit seepage fault.
Background technique: existing domestic steel burning line is more and more, and because of the seepage of constructing and corrosion causes happens occasionally, the very first time is finished the important duty that the repairing task is pipeline management work.Have now and be used to safeguard that the utensil of repairing steel conveyance conduit seepage fault is mainly the pressure sealing holding tube, it mainly is made up of upper and lower two semicircle volts of breathing out, first circular volt of breathing out is provided with conduction hole and supporting ball valve, and upper and lower two semicircle volts of breathing out are fixed in the pipe leakage place by the screw of screw rod by its both sides.The deficiency that the pressure sealing holding tube in use exists is: 1, product has the many places seal point in design, has stayed the hidden danger of gas leakage; 2, operability is not strong, and operation is prepared loaded down with trivial details, and the cleaning pipeline area is big, and labor strength is big; 3, press via hole little in the product drainage, effect of easing stress is bad, is unfavorable for that welding waits follow-up work to carry out.
Summary of the invention: the purpose of this utility model is, the deficiency that in use exists at existing pressure sealing holding tube, and propose that a kind of product specification science, strong operability, drainage are unobstructed, the steel pipe pressure sealing cover plate of good sealing effect.
Can realize the purpose of this utility model by following technical proposals, a kind of steel pipe pressure sealing cover plate, it is characterized in that, it is made up of leak stopping cover plate, ball valve, drainage tube, fast-assembling pressing plate, fast-assembling pressing plate upper shield is on the leak stopping cover plate, ball valve is connected with drainage through hole spiral on the leak stopping cover plate, and drainage tube is connected with ball valve, and the fast-assembling pressing plate is provided with the device that is fixed on the steel pipe.
For making the leak stopping cover plate that good withstand voltage properties and a pressure Free up Memory be arranged, leak stopping cover plate middle part is made as the circular arch of epirelief.
For making device that good sealing be arranged, be provided with sealing plug to be opened/closed in the inner port of leak stopping cover plate drainage through hole.
Sealing plug is connected with the inner port spiral of leak stopping cover plate drainage through hole, and the cross section of sealing plug through hole is a square, can sealing plug be moved up and down in rotation by inserting cubic bar rotation.
The set device that is fixed on the steel pipe is meant on the fast-assembling pressing plate: a flexible steel band, an end are fixed on the leak stopping cover plate, and the other end is provided with screw thread and is furnished with tightening nut.
The external port of leak stopping cover plate drainage through hole is provided with the pipe thread plug, and it is loaded onto after ball valve and drainage tube unload.
Effect of the present utility model is: 1, easy for installation, quick, labor intensity is low, this is that mainly the fixing device on the fast-assembling pressing plate is the flexible steel band of being furnished with nut, during installation, only need the flexible steel band mounting end is passed mounting hole on the fast-assembling pressing plate, put tightening nut and tighten and get final product; 2, the overcurrent latus rectum is big, cavity pressure is low, help welding procedure is carried out in the cover plate outer, this is that leak stopping cover plate middle part has been made as the circular arch of epirelief, the approach of direction of flow drainage through hole is unimpeded, and the circular arch of epirelief provides a pressure Free up Memory, so can make cavity pressure low, is beneficial to welding.3, good sealing effect, this is that this device is provided with double seal, the one, and the set sealing plug to be opened/closed of inner port of leak stopping cover plate drainage through hole, the 2nd, the set pipe thread plug of external port of leak stopping cover plate drainage through hole, this double seal secret emissary must seal effective, and performance is safe and reliable.
Below in conjunction with drawings and Examples the utility model is further set forth:
Description of drawings:
Accompanying drawing 1 is a sectional structure schematic representation of the present utility model;
Accompanying drawing 2 is an A place structure for amplifying schematic representation in the accompanying drawing 1.
Embodiment:
Referring to accompanying drawing 1,2, a kind of steel pipe pressure sealing cover plate, it mainly is made up of leak stopping cover plate 1, ball valve 2, drainage tube 3, fast-assembling pressing plate 4, fast-assembling pressing plate 4 upper shields are on leak stopping cover plate 1, and ball valve 2 is connected with drainage through hole spiral on the leak stopping cover plate 1, and drainage tube 3 is connected with ball valve 2, fast-assembling pressing plate 4 is provided with the device that is fixed on the steel pipe 5, this device is a flexible steel band 41, and its end is fixed on the fast-assembling pressing plate 4, and the other end is provided with screw thread and is furnished with tightening nut.For making leak stopping cover plate 1 that good withstand voltage properties be arranged, leak stopping cover plate 1 middle part is made as the circular arch of epirelief.For making device that good sealing be arranged, be provided with sealing plug 11 to be opened/closed in the inner port of leak stopping cover plate 1 drainage through hole, be the spiral connection between them, the through hole cross section of sealing plug 11 is square.The external port of leak stopping cover plate 1 drainage through hole is provided with the screw thread that is connected with pipe thread plug 12 spirals, and pipe thread plug 12 is loaded onto after ball valve 2 and drainage tube 3 unload.
The operation procedure of this device is: the sealing plug to be opened/closed on the leak stopping cover plate 1 11 is opened, fast-assembling pressing plate 4 upper shields are on leak stopping cover plate 1, flexible steel band 41 encircled steel pipe 5 and pass mounting hole on the fast-assembling pressing plate 4, put tightening nut and tighten and fast-assembling pressing plate 4 can be fixed on the steel pipe 5.Ball valve 2 is connected with drainage through hole spiral on the leak stopping cover plate 1, and drainage tube 3 is connected with ball valve 2.Implement the step-down drainage, behind cleaning leak stopping cover plate 1 periphery,, close ball valve 2 again and realize leak stopping along the welding of cover plate outer.Remove drainage tube, close sealing plug 11 to be opened/closed with the cubic bar of interior operation by ball valve 2, tear ball valve 2 again open, remove fast-assembling pressing plate 4, screw on pipe thread plug 12, leak stopping work is finished.
