Abstract
The utility model relates to a pipe connector which is composed of a connector main body, a sealing end cover and a sealing rubber ring. In order to avoid the threading process of pipe connection, reduce the labor intensity, improve the efficiency and decrease the cost of the pipe connector, the utility model does not need to process screw threads on the pipe connector. The utility model is characterized in that two pairs of outward or inward clamping claws are respectively arranged on the pipe connector main body and the sealing end cover and are mutually fastened and are oppositely rotated for an angle of 45 DEG. The sealing rubber ring between the pipe connector main body and the sealing end cover is squeezed to deform so as to achieve the sealing connecting function. The pipe connector belongs to a flexible interface, and the anti-vibration performance is good. The pipe connector has a telescopic allowance from 20 mm to 30 mm, and can be widely used for fast connecting and rush to repair metal pipes, plastic pipes, glass pipes, etc.
Description
The utility model is about pipe joint, and particularly about clamp-press type rubber sealing pipe joint, this pipe fitting is by a main pipe body, two rubber rings, and two end covers combine.
Known traditional pipe connecting method is to use special tool to process screw thread at the two ends of metallic conduit, be equipped with the threaded pipe fitting of corresponding bore again, this threaded pipe fitting adopts flax silk or gives birth to mould to be with and is stuffing box packing when connecting, labor intensity is big in the construction, and leakage loss is corroded at the screw thread place easily; The plastic bonding technology is adopted in the connection of plastic pipe more, it is bonding to need special-purpose binder that pipeline and plastic pipe are carried out when bonding, general plastic adhesive contain more harmful material for the pipeline construction in the industries such as feedwater, food, pharmacy inapplicable and gluing of surfaces handle the seepage of not taking pains.
The purpose of this utility model be for a kind of good seal performance is provided, connect reliable, can reduce labor intensity and can significantly improve the novel pipe fitting of work efficiency, another purpose of the present utility model is that the cost of pipe fitting reduce to be made is easier, as long as have general casting and the machining ability just can be produced.
The utility model pipe fitting is when carrying out the pipeline connection, tubing is passed end cover in elder generation and O-ring seal inserts in the main pipe body again, with the relative 45 degree that rotates of end cover with main pipe body, make the distortion that is squeezed of sealing rubber ring between main pipe body and the end cover, promptly reached the effect of being tightly connected.
Fig. 1. be to use clamp-press type rubber sealing pipe collar connecting tube generalized section.
Fig. 2. be main pipe body upper clipping claw schematic representation.
Fig. 3. be the sealing rubber ring sectional schematic diagram.
From Fig. 1. as can be known, on the outer rim at main pipe body interface position, two ends 1., every end all have the outstanding outward claw of two subtends 4. with end cover interface position inner edge 3. on the inwardly outstanding claw of two couples 5. be interlocked, the distortion so that 2. sealing rubber ring is squeezed, be filled in main pipe body 1., end cover 3. and pipeline play seal action between 6..For making sealing effect better, prevent that the 6. interior material of pipeline from leaking outside, the sealing position of main pipe body inboard, interface position 1. is the inclined-plane at 30 ° of angles, the inclined-plane that the 3. inner trailing edge of end cover is 60 ° of angles, purpose are to make this inclined-plane 2. sealing rubber ring to be implemented the active force of both direction in spinning process.The one, axial force mainly plays the crush seal cushion rubber and 2. acts on, and the 2nd, radial force mainly is the frictional force raising join strength that 2. increases pipeline and pipe fitting by O-ring seal.
Fig. 2. the main pipe body that is shown in 1. the interface position claw 4. leading portion be designed to have 20 °~slideway on 30 ° of inclined-planes so that when rotation extruding cushion rubber more laborsaving and easy disassembling.At claw middle part 4., be provided with location groove and an end cap 3. the claw on the inner edge 5. the prominent muscle at middle part match, its effect is to prevent to be shaken the back dropout.
Fig. 3. shown in sealing rubber ring section configuration 2. be the irregular polygonal that double trapezoid is formed with six limits, wherein the number of degrees of four adjacent drift angles be respectively 30 °, 60 °, 120 ° and 90 ° corresponding to main pipe body 1. with the inclined-plane at end cover sealing position 3., tight to guarantee interface.
For the convenience on loading and unloading, the main body of this novel pipe fitting 1. with end cover 3. periphery make the prism of 16 limit shapes, be beneficial to use spanner or pipe wrench operation.
The utility model also has an advantage except removing mantle fiber technology from pipeline construction, namely the interface of this pipe fitting becomes to flexibly connect, overcome the defective that rigid interface can not corner, and the flexible surplus that has 20mm~30mm in the big situation of difference variation is more suitable for the needs of environment is poor, soil condition is bad field, mining area, interim mutability and operation in wartime. Feedwater, coal gas, heating power, oil, chemical industry, heating and ventilation etc. be can be widely used in and quick connection and the leakage loss repairing of metallic conduit, plastic conduit, glass pipe etc. used.
Claims (3)
1, pipe joint, a kind of by a main pipe body, two O-ring seals, two pipe joints that end cover combines, it is characterized in that claw outstanding outside two subtends being arranged in main pipe body interface position outer rim, its end cover interface position inner edge has two pairs of inwardly outstanding claws, one sealing rubber ring is arranged between its main pipe body and the end cover, and the section configuration of this rubber ring is an irregular polygon.
2, as the described pipe joint of claim 1., it is characterized in that the claw front portion on the outer rim of main pipe body interface position, inclined-plane with 20 °~30 °, there is a location groove at the claw middle part, claw on its end cap inner edge middle part have one with the main pipe body outer rim on the prominent muscle that matches of the groove at claw middle part, the section configuration of its sealing rubber ring is the Hexagon of double trapezoid composition.
3, as claim 1. or the described pipe joint of claim 2., it is characterized in that inner seal portion position, main pipe body interface position has the inclined-plane at 30 ° of angles, its end cover inside back sealing position has the inclined-plane at 60 ° of angles, and the section of its rubber seal is the number of degrees that four interior angles are arranged in the Hexagon and is respectively 30 °, 60 °, 120 ° and 90 °.
