Abstract

The utility model relates to a ball expanding type plug which can dredge liquid pipelines and gas pipelines and is composed of a rubber expansion ball, a main rope penetrating through the rubber expansion ball, an auxiliary rope, a supporting claw, a cystoid elastic inner pipe, a tubular rubber inner pipe, an inner clamping plate, an outer clamping plate, an upper clamping plate, a lower clamping plate, a flexible pipe, etc. The utility model is characterized in that a gate valve is saved, the construction can be carried out without closing the gate valve; water for production and domestic water of each user can not be affected; the work efficiency is improved; the utility model which is convenient and reliable can be used repeatedly, and the ball expanding type plug without the tubular rubber inner pipe or the spring can be a simple expanding plug used for the maintenance of water pipelines, liquid pipelines and gas pipelines. The utility model can be applied to oil pipelines, water pipelines and gas pipelines of residents and enterprises.

Description

Ball expanding type plug for pipeline

The utility model relates to a kind of liquid, feed channel plug, particularly a kind of device that keeps in repair mediation transmission liquid, gas pipeline.

The screw end plug is all adopted in existing pipeline maintenance, mediation etc., its maintenance procedures is more, and when the bad pipeline of maintenance rust, tap and gate valve, all need turn off front end and divide gate valve, divide the gate valve rust dead as front end, shut total gate valve again, give building resident's life, the production of factory etc. is all made troubles and is lost.

The pipeline ball that the purpose of this utility model is exactly to design a kind of maintenance procedures for fear of above-mentioned the deficiencies in the prior art is few, easy to use, can be not related to gate valve during maintenance, the do not cut off the water plug that expands.

The purpose of this utility model realizes by following structure: the bloated plug of pipeline ball is by the bloated ball of rubber, pass the stay cord of the bloated ball of rubber, pipe and supporting claw are formed in the cryptomere elasticity, bolted pressing plate of one valve and the clamping plate top by the bloated ball of interior external compression rubber is arranged on the stay cord top, rubber is bloated, and the ball bottom is by the inner splint that is through on the stay cord, external splint is clamped, on the interior pipe of cryptomere elasticity, following two ends are fastened on respectively, on the die holder, supporting claw is fixed on the external splint by bearing pin, in elasticity, have in the pipe one the location spring tubular rubber in manage, on the interior pipe of tubular rubber, following two ends are fastened on respectively, die holder, retaining spring in it is fixed on the main rope, there is a kayser at the middle part of positioning spring, kayser cooperates with the snap ring that is withstood by spring in the external splint lower end, and secondary rope passes the snap ring spring and ties up on the snap ring.Certain air pressure and sealing are fully arranged in the bloated ball of rubber.

It is few that the utility model compared with prior art has maintenance procedures, easy to use, advantage such as closing gate valve not during maintenance, use when being fit to maintenance of building water supply water pipe and the maintenance of plant produced water water pipe.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

1 bolt, 2 arm-ties, 3 bolts, 4 pressing plates, 5 clamping plate, 6 bloated balls, the interior pipe of 7 cryptomere elasticity, 8 kaysers, 9 retaining springs, the interior pipe of 10 tubular rubbers, 11 stay cords, 12 supporting claws, 13 inner splints, 14 external splints, 15 snap rings, 16 snap ring springs, 17 secondary ropes, 18 clamping plate, 19 flexible pipes among the figure.

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in the figure: the bloated plug of pipeline ball is by bloated ball 6, pass the stay cord 11 of the ball that expands, pipe 7 and supporting claw 12 are formed in the cryptomere elasticity, have for 2 times by bolt 1 at stay cord top arm-tie, 3 pressing plate 4 and the clamping plate 5 that link, pressing plate 4 and clamping plate 5 clamp the bloated ball top of rubber inside and outside rubber expands ball, rubber is bloated, and the ball bottom is by the inner splint 13 that is through on the stay cord, external splint 14 is clamped, on the interior pipe of cryptomere elasticity, following two ends are fastened on respectively on clamping plate 5 and the inner splint 13, in expanding ball, rubber have one to be covered with in the tubular rubber of retaining spring 9 and to manage 10 on the main rope, the retaining spring middle part is fixed with a kayser 8, the snap ring 15 that is withstood by the snap ring spring is arranged below external splint, secondary rope passes spring and ties up on the snap ring, and snap ring is put kayser by snap ring spring and secondary rope control card, on external splint by bearing pin fixed support pawl.

When using the utility model, the master of leaving behind restricts, the gas that the ball sealing is advanced by unidirectional valve bolt owing to expand is compressed, the ball that expands is expanded to the two side, and stifled tight conduit pipeline, the ball that expands expand supporting claw are rotated, pawl is lived water pipe, spring on the main rope glides, and the kayser on it is stuck on the snap ring, and then can keep in repair water pipe this moment.When the secondary rope of pulling, compression snap ring spring, snap ring moves back kayser, and the bloated ball air pressure of portion and the effect of elastic force within it restores to the original state down, pulls out plug and then can from water pipe.As remove and manage in the cryptomere elasticity in the ball that expands etc., then can form simple and easy plug by bloated ball, the main rope at supporting claw etc.

Claims

1, a kind of pipeline ball plug that expands, it is characterized in that: it is ball 6 because rubber expands, pass the stay cord 11 of the bloated ball of rubber, pipe 7 in the elasticity, supporting blade tooth 12 forms, have by bolt 1 on the stay cord top, 3 pressing plates 4 that connect and clamping plate 5 clamp the top of the bloated ball of rubber, rubber in the stay cord bottom is bloated, and the ball bottom is to be clamped by inner splint 13 and external splint 14, on the interior pipe of elasticity, following two ends are fastened on respectively, on the die holder, supporting claw is fixed on the external splint by bearing pin, in elasticity, have one to be covered with in the tubular rubber of retaining spring and to manage in the pipe on main the rope, there is a kayser 8 at the middle part of retaining spring, the snap ring 15 that is withstood by spring is arranged in the external splint lower end, and secondary rope 17 passes snap ring spring 16 and ties up on the snap ring.

2, the bloated plug of pipeline ball as claimed in claim 1, it is characterized in that: bolt 3 is selected unidirectional valve bolt for use.
