Drawings
Fig. 1 is the tiling schematic diagram of the sealing gasket of the present invention.
Fig. 2 is a schematic view of the use structure of the present invention.
Detailed Description
As shown in fig. 1 or 2, the flat plate gasket 100 for repairing a drinking water pipe is provided with a sealing surface 120 on the inner surface 111 of the flat plate gasket 100, a grid-shaped sealing protrusion 121 is provided on the sealing surface 120, and a square sealing groove 122 is provided in the grid-shaped sealing protrusion 121.
The outer side 112 of the flat gasket 100 is provided with an anchor ear groove 130 for cooperating with the anchor ear 200, and the groove bottom 131 of the anchor ear groove 130 is a flat bottom or a convex arc bottom, and what kind of groove bottom 131 is specifically set, which can be determined according to the clamping requirement of the anchor ear 200.
An elliptical hole 101 is formed in the middle of the flat plate gasket 100, and a sealing strip 102 is arranged around the edge of the elliptical hole 101. The elliptical hole 101 in the middle of the flat plate sealing gasket 100 is specially designed for a three-way pipeline, and the sealing strip 102 protruding from the edge of the elliptical hole 101 is circular after being bent and just aims at the pipe orifice of the three-way pipeline, so that a good sealing effect is achieved.
After the sealing surface 120 of the flat gasket 100 is wrapped at the leakage or damage position of the pipeline 300, the anchor ear 200 is placed in the anchor ear groove 130 and then tightened, and the leakage or damage position of the pipeline 300 is sealed through a plurality of square sealing groove 122 structures of the sealing surface.
The anchor ear 200 may be mounted on the outer side of the plate gasket 100 by providing an adjustable locking means or a mating bolt or nut.
When the pipeline leaks or is damaged, the sealing surface 120 of the flat plate gasket 100 is wrapped at the leaking or damaged position of the pipeline, then the hoop 200 is placed in the hoop groove 130, the hoop 200 is contracted, and after the hoop is closed, a plurality of square sealing grooves 122 and latticed sealing convex strips 121 on the sealing surface 120 generate a plurality of water leakage prevention barriers between the inner side surface 111 of the gasket 100 and the surface of the pipeline 300, so that a good sealing effect is achieved.
The flexible circumferential repair hoop 200 may be formed of one or more sections of stainless steel bands, firmly connected to a cast locking member (not shown in the drawings), installed on the pipeline 300 by bolts and nuts (not shown in the drawings), and sealed in a unique tapered overlapping manner, providing continuous, uniform sealing for hoops 200 of all calibers, and being a quick, durable, and economical maintenance solution.
The stainless steel band is made of stainless steel and has the characteristics of corrosion resistance, high toughness, high strength and the like. (not shown) a stainless steel band is attached, provided with guide pieces (not shown) which support each other. Allowing maximum torque for the applicable bolt. The locking element design includes a self-tightening fastener, has no loose parts, and can be conveniently installed in adverse environments, thereby saving time.
When repairing the leakage or damage of the pipeline, the method is convenient and quick, saves cost, has the characteristics of high temperature resistance, high pressure resistance, corrosion resistance, long service life and the like, and is labor-saving, flexible and reliable in operation.
The flat plate gasket 100 for repairing drinking water pipes can provide a quick and economical repairing method for various damages such as fracture, perforation, crack, etc. of various pipes such as cast iron pipes, steel pipes, cement pipes, copper pipes, aluminum pipes, plastic pipes, glass fiber pipes, etc. The plurality of square seal grooves 122 and the plurality of latticed seal ridges 121 on the sealing surface 120 provide a large amount of water leakage prevention barriers between the inner surface 111 of the gasket 100 and the surface of the pipe 300, thereby achieving a good sealing effect.
The strength of the flat gasket 100 for repairing drinking water pipes is up to 6.8Mpa or more, and the compression set is 20%. Various indexes of the performance of the flat plate sealing gasket 100 for repairing the drinking water pipeline are reasonably optimized to achieve the best use quality.
The flat plate sealing gasket 100 for repairing the drinking water pipe is certified by international NSF, meets the drinking water standard of NSF61, and is specially used for repairing the fracture and leakage of the drinking water pipe.
