Abstract

The utility model provides a connecting device for end-sealed diameter-fixed hose and rigid pipe, comprising a connecting head of the hose and rigid pipe with inner step and a rigid pipe diameter chock which is connected with the connecting head of the hose and rigid pipe by a screw. The end face of the inner step of the connecting head of the hose and rigid pipe is provided with a sealing ring, and the side wall of the rigid pipe diameter chock is provided with a bolt hole on which a set screw is screw connected. The utility model has the advantages of simple structure, low cost, convenient assembly and disassembly, time saving, high reliability and strong versatility. The utility model is used in the connection of the hose and the straight barrel shaped inlet and outlet of the pump which is arranged and dismounted frequently and requires the reliable sealing or the connection of the rigid pipe and the hose with various specification.

Description

Connecting device for hose and rigid pipe

The utility model relates to a kind ofly be used for normal dress, need the straight tubular of pump class of reliable sealing import and export with flexible pipe connect or the hard tube of all size seals with the end that connects of flexible pipe and directly decides the soft or hard pipe connector.

Now generally be used in normal mounting or dismounting, need the soft or hard pipe of reliable sealing to be connected with three kinds, be i.e. flange-type connection or scyewed joint or directly connection.The hard tube that flange-type connects needs special making flange plate, and must combine as a whole with hard tube.Because flange plate need cast or weld, increase processing charges and changed the reset condition of hard tube, because of two flange plate when the connection are that the plane joins, no guidance quality, installation acquires a certain degree of difficulty.The Thread Machining Process of scyewed joint is difficult, and metal end is also very easily got rusty, and sealing reliability is poor, if there is not the sheath buckle type inipple, when mounted, flexible pipe produces distortion along with screw thread together rotates, and makes installation more inconvenient.When directly connecting, because sealing, requirement such as fastening mount and dismount all very difficult.Iron wire after tying up is unrenewable, pricks bad flexible pipe and need cut away etc. thereby go back waste material.

The purpose of this utility model be used for normal mounting or dismounting in order to provide a kind of, need the straight tubular of pump class of reliable sealing import and export with flexible pipe connect or the hard tube of all size and flexible pipe connect, mounting or dismounting are convenient, pilot seal is reliable, material-saving when highly versatile, joint, end simple in structure seal and directly decide the soft or hard pipe connector.

The utility model is achieved like this: the utility model is by the soft or hard pipe coupling head of ladder in the band, form with the hard tube footpath price fixing of soft or hard pipe coupling head scyewed joint, on the interior ladder end face of soft or hard pipe coupling head, seal ring is housed, on the sidewall of hard tube footpath price fixing, screw is arranged, scyewed joint has Cock screw (referring to Fig. 1 on the screw, Fig. 2), during the utility model work, the soft or hard pipe coupling head of adorning firm flexible pipe is enclosed within on the hard tube of the smooth mouth of pipe, make the seal ring on the ladder end face in the coupling head of soft or hard pipe be close to the end face of hard tube, imposing radial force to the hard tube radial transmission line then is fixed on the hard tube, and by passing the tension of soft or hard pipe joint bolt parallel to an axis, make the seal ring that is positioned at end face be subjected to the effect of axial force and extrusion-deformation reaches sealing effect.

The groove of dress seal ring is arranged on the interior ladder end face of the soft or hard pipe coupling head in the utility model, and seal ring is " O " RunddichtringO (referring to Fig. 2), and sealing effect is better.

In the screw on the sidewall of the hard tube footpath price fixing in the utility model tightening rubber column (referring to Fig. 2) is housed.Cock screw passes screw and pushes down the tightening rubber column and tightly suppress hard tube, strengthens sealing effect.

Between Cock screw in the screw-in screw on the hard tube footpath price fixing in the utility model and tightening rubber column plain cushion (referring to Fig. 2) is housed, avoids Cock screw directly to contact, can protect the tightening rubber column with the tightening rubber column.

The head inclination of the soft or hard pipe coupling head in the utility model is in its end face, with the needs (referring to Fig. 3) that adapt to varying environment.

The utlity model has advantages such as simple in structure, that cost is low, mounting or dismounting are easy to use, the material-saving that saves time, pilot seal reliable, highly versatile, and is applied widely.Can be used for normal mounting or dismounting, need the straight tubular import and export of pump class of reliable sealing and connecting or the hard tube of all size and connecting of flexible pipe of flexible pipe.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1: the utility model structural representation

Fig. 2: A-A sectional view among Fig. 1

Fig. 3: another implements illustration the utility model

The explanation of each sequence number among the above figure:

1 interior ladder 2 hose-rigid pipe coupling heads 3 hard tubes footpath price fixing 4 grooves 5 sealing rings 6 heads 7 end faces 8 nipple orifice 9 screws 10 screws 11 screws 12 tightening rubber columns 13 plain cushions 14 holding screws 15 flexible pipes 16 hard tubes

The utility model is by the soft or hard pipe coupling head 2 of ladder 1 in the band, and hard tube footpath price fixing 3 is formed.Fluted 4 on the end face of the interior ladder 1 of soft or hard pipe coupling head 2, " O " RunddichtringO 5 is housed in the groove 4, on the protuberance of four symmetries on the end face 7 of soft or hard pipe coupling head 2, be drilled with nipple orifice 8.On the end face of hard tube footpath price fixing 3 with the end face 7 of soft or hard pipe coupling head 2 on the corresponding position of nipple orifice 8 on screw 9 is arranged.Screw 10 passes and makes soft or hard coupling head 2 and hard tube footpath price fixing 3 scyewed joint in the nipple orifice 8 screw-in screws 9.Be arranged with two screws 11 on the sidewall of hard tube footpath price fixing 3, the tightening rubber column 12 of packing into successively in the screw 11, plain cushion 13, Cock screw 14 screw in the screws 11 and compress tightening rubber column 12 by plain cushion 13.

Head 6 tiltables of the soft or hard pipe coupling head 2 in the utility model are in its end face 7, and its inclination is 25 ° (referring to Fig. 3).

Using method of the present utility model is as follows:

The soft or hard pipe coupling head 2 of the flexible pipe made from plastics or rubber material 15 that installed is enclosed within on the hard tube made from metallic material 16 of the smooth mouth of pipe, and make the seal ring 5 on ladder 1 end faces in the soft or hard pipe coupling head 2 be close to the end face of hard tube 16, make hard tube footpath price fixing 3 end faces and soft or hard pipe coupling head 2 end faces that gap more than 3 millimeters is arranged then, screw Cock screw 14 on the price fixing 3 of hard tube footpath and make it have good fasteningly with hard tube 16, symmetry screws the screw 10 on soft or hard pipe coupling head 2 and the hard tube footpath price fixing 3 again.When seal ring 5 is subjected to certain extruding and after reaching sealing, can drops into normal use.
