Description

Technical Field

[0001] The utility model relates to the technical field of grooved pipe connectors, in particular to a high-pressure resistant grooved pipe connector. Background Art

[0002] Grooved pipe fittings are a new type of steel pipe connection fittings, also called clamp connections. Pipe connectors are a type of equipment that uses stainless steel and rubber to form a component combination device to achieve a sealing and pressure-bearing function. The structure is very compact. Put the connecting sleeve on the two ends of the pipe to be connected, tighten the side bolts, and the connecting sleeve is fixed on the surface of the pipe end to achieve limit fixation.

[0003] Common groove pipe connectors are generally installed on the end face of the groove pipe through a connecting sleeve, the pipe mouths of the groove pipe are connected, and then the connecting sleeve is installed at the connection of the pipe. The bolts are rotated to make the connecting sleeve and the connection of the pipe closely contact, so as to connect the pipes. However, since the groove pipe is generally installed below the ground and is under high pressure for a long time, the connection of the groove pipe is easily squeezed and bent, and the connecting sleeve will be difficult to stably seal the groove pipe.

[0012] Preferably, a limiting plate is installed on the upper surface of the connecting sleeve, and limiting openings are opened on both sides of the pressure plate. The limiting openings are sleeved on the surface of the limiting plate. The limiting plate and the limiting opening cooperate to limit the pressure plate so that the pressure plate can move vertically.

[0013] Preferably, slide plates are installed on both sides of the pressing block, and slide grooves are opened on the inner walls of both sides of the limiting frame. The slide plates are embedded in the inner cavity of the slide grooves. The slide plates cooperate with the slide grooves to limit the pressing block so that the pressing block can move vertically.

The pressing block and the extrusion head are both trapezoidal in design, so that the pressing block can squeeze the extrusion head when moving downward, thereby squeezing the connecting sleeve.

[0015] Preferably, a limiting block is installed on the upper part of the inner cavity of the limiting frame, and the limiting blocks are in close contact with the pressing blocks at the corresponding positions. The limiting blocks can limit the pressing blocks so that the pressing blocks can only move in the direction of the extrusion head to extrude the extrusion head.

When the groove pipe is subjected to pressure, the pressure plate will be squeezed, and the pressure plate will bend downward to drive the moving block to move downward. The pressing block will also move downward due to the limitation of the limit frame to squeeze the extrusion head. The extrusion head will be squeezed toward the side of the connecting sleeve, so that the side of the connecting sleeve can still be tightly attached to the surface of the groove pipe, the connecting sleeve will not be easily deformed, and can effectively seal the connection of the groove pipe, so that the groove pipes are not easy to separate.

The connecting sleeve 1 is installed at the connection of the groove pipe. The rotating threaded rod 3 can drive the mounting plate 2 to be connected, so that the connecting sleeve 1 can be stably installed on the surface of the groove pipe to connect the groove pipe. When the groove pipe is under pressure, the pressure plate 4 will be squeezed, and the pressure plate 4 will bend downward to drive the moving block 5 to move downward. The pressing block 6 will also move downward due to the limitation of the limit frame 7 to squeeze the extrusion head 8. The extrusion head 8 will be squeezed toward the side of the connecting sleeve 1, so that the side of the connecting sleeve 1 can still be in close contact with the surface of the groove pipe. The connecting sleeve 1 will not be easily deformed, and can effectively seal the connection of the groove pipe, so that the groove pipes are not easy to separate;

[0031] See also Figure 3 , the upper surface of the connecting sleeve 1 is equipped with a limit plate 9, please refer to Figure 4 , both sides of the pressing plate 4 are provided with limiting openings 10, and the limiting openings 10 are sleeved on the surface of the limiting plate 9. The limiting plate 9 cooperates with the limiting openings 10 to limit the pressing plate 4, so that the pressing plate 4 can move vertically;
