Detailed Description

The features and principles of the present invention will be described in detail below with reference to the accompanying drawings, and the illustrated embodiments are only for explaining the present invention, and do not limit the scope of the present invention.

The pipe clamp for connecting the PE pipe and the groove valve/groove steel pipe comprises a clamp main body, wherein a PE loop 2 is arranged on one side of a clamp 1, as shown in figures 1-3. The checkpost includes that the main part of two butt joints is the card body of semicircular structure, and two card body cooperations are connected two card body butt joints together through two bolt 3. The butt joint clamp body connects the PE loop and the groove valve/groove steel pipe 13 together.

Specifically, bayonets 4 connected with the steel pipe groove and the PE loop are respectively arranged on two sides of the clamping body. The two sides of the semi-circular structure of the clamp body main body are respectively provided with a boss 5, and the bosses 5 are provided with bolt holes convenient for bolt connection. After the two clamping bodies are butted, bosses on two sides of the two clamping bodies are also in corresponding positions, bolts penetrate through bolt holes in the bosses 5, and are screwed and fixed by nuts 6. Need not to use the lap joint flange, reduced the bolt use amount, only tighten 2 bolts just can realize the connection of PE pipe and slot valve/slot steel pipe 13.

The inner wall of the clamp body is provided with a semicircular clamping groove 7 matched with a loop head of the PE loop and a sealing ring groove 8 matched with a steel pipe groove, and a sealing ring 9 is arranged in the sealing ring groove. The shape of the clamping groove corresponds to the loop head of the PE loop, and the end part of the semicircular clamping groove matched with the loop head of the PE loop is provided with a slope 10. The ramp 10 is inclined outwards, and the design is firstly to make the assembly with the PE loop easier; and secondly, the end face is compressed, and acts on the sealing ring to axially seal the rubber ring.

The vertical wall 11 and the side wall 12 of the sealing ring groove matched with the steel pipe groove are also provided with slopes, an included angle larger than 90 degrees is formed between the vertical wall and the side wall, and the sealing ring is axially compressed. During connection, one side of the sealing ring is pressed on the valve and the outer wall of the steel pipe by virtue of pretightening force, and the other side of the sealing ring is pressed by virtue of radial pressing force, so that the inclined surface is tightly attached to the inner wall of the connecting clamp; when rivers pass through, water pressure can press the sealing washer on checkpost inner wall and valve, steel pipe outer wall, plays self sealss effect.

The PE loop is used for a universal loose flange in the market and is made of PE materials, and the PE loop is hot-melted with a pipeline when in use.

Checkpost, bolt, sealing washer and PE loop adopt preassembling to dispatch from the factory, just slot end bayonet joint adopts the fast-assembling structure, and the rubber coating is handled in the bolt outer end when dispatching from the factory, prevents that the pre-installation bolt from droing.

As shown in figures 4 and 5, when the device is used, the PE loop is connected with a pipeline, then the groove valve/groove steel pipe is directly inserted into the groove end of the pipe clamp to realize quick assembly, finally, the bolt is tightened, the loop plane can be tightened through the pipe clamp to be connected with the groove valve/groove steel pipe, and the rubber ring is used for sealing.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements of the present invention may be made by those skilled in the art without departing from the spirit of the present invention, which is defined by the appended claims.
