Description

Rubber gasket for pipeline joint

Technical Field

The utility model relates to a rubber gasket for pipe connection department.

Background

The rubber gasket is a sealing part, and the common pipeline, the equipment route that are used for all kinds of existence fluids of being arranged in, like daily work, life for be used for between connecting device valve or water pump and other parts being used for the pipeline that forms the direction to the fluid, the pipeline including outer tube, inner tube, the joint is spacing between outer tube and the inner tube, two adjacent inner tube opposite end walls between be provided with the rubber gasket, two adjacent outer tubes between be provided with radial extension's journal stirrup, wear to establish the bolt through between two journal stirrups, form the fastening between two pipelines to form by the rubber gasket with two inner tube end wall butts and seal, the clearance that exists on two inner tube end walls is filled through the rubber gasket pressurized deformation back to specific sealed principle. However, during prior art's pipeline and rubber gasket cooperate, on the one hand often need set up protruding muscle or recess on the inner tube end wall, guarantee the location to the rubber gasket in installation and the later stage use, on the other hand when the pump body or the valve in fields such as specifically being applied to blowdown, because fibre and solid impurity often exist in the fluid of this type of equipment processing, equipment is at the moving in-process, lead to the pipeline to produce great vibration easily for the bolt of outer tube journal stirrup department is not hard up, produce and reveal and damage.

SUMMERY OF THE UTILITY MODEL

The utility model provides a be convenient for install the location, and can prevent the not hard up rubber gasket that is used for the pipe connection department of pipe connection department.

In order to achieve the purpose, the utility model provides a rubber gasket for pipe connection department, including the gasket body, the periphery wall department of gasket body is provided with a plurality of radially extending's connecting portion, a plurality of connecting portions correspond the screw position extension setting of outer tube respectively, and be provided with the opening that can supply the bolt to wear to establish on the connecting portion.

The technical scheme has the advantages that: through a plurality of connecting portions that extend to the screw position of outer tube by the gasket body, and be provided with the opening that supplies the bolt to wear to establish on the connecting portion, when installation or use, can pass through the cooperation relation between connecting portion and the bolt, form the location of gasket body, be convenient for install the location, need not to set up on the end wall of inner tube and form spacing protruding muscle or recess to the gasket body, and be located connecting portion between the adjacent outer tube behind the outer tube spiro union location, can provide the reverse elastic force of two outer tubes of impelling because self deformation, make outer tube screw and screw thread both's flank tightly butt, prevent because pipeline vibration, make the bolt not hard up, guarantee pipeline connection's stability.

The utility model discloses can further set up to: connecting portion be the arc setting that diminishes towards its extending direction, be formed with the interval section between the adjacent connecting portion, and the thickness of two pipeline directions of orientation of connecting portion is greater than the gasket body.

Through further setting, be the gradually little arc shape of its extending direction with connecting portion setting, and adjacent connecting portion interval sets up, reduces the use of material, reduce cost to thicken connecting portion, guarantee that it can provide sufficient elastic force, guarantee that the outer tube passes through bolted connection back, outer tube screw and screw thread both's flank of thread can tightly the butt.

The utility model discloses can further set up to: the radius of the opening is larger than that of the screw hole.

Through further setting up, avoid in the installation, the condition of mutual interference takes place between connecting portion and the bolt, the holistic installation of pipeline of being convenient for.

The utility model discloses can further set up to: the gasket body is provided with a plurality of upper concave parts and lower concave parts towards two adjacent pipelines at two ends respectively, and the inner walls of the upper concave parts and the lower concave parts can deform and abut against the end walls of the inner pipes when the two inner pipes are tightly pressed with the gasket body.

Through further setting up, at piping erection's in-process, two inner tubes compress tightly on the gasket, promote go up concave part and lower concave part inside air of discharging and butt on the end wall of inner tube for even the pipeline produces great vibration, the last concave part and the lower concave part of gasket body also can be far away from external atmospheric pressure because self inside atmospheric pressure, and be difficult for two duct separation, avoid the interior fluid of pipeline to ooze, guarantee the waterproof performance of gasket body.

The utility model discloses can further set up to: the upper concave parts and the lower concave parts are uniformly distributed along the circumferential direction of the gasket body, and the distance from the upper concave parts to the axis of the pipeline is greater than that of the lower concave parts.

Through further setting up for go up the concave part and all be the annular with the concave part down, the protection is even, and the distance of going up the concave part to pipeline axle center is greater than the concave part down, avoids producing the interference between the two.
