Abstract

The utility model discloses a pressure application tooling for a pipe. The tooling comprises a pressure application joint (1), an O-ring I (2), a locknut (3), a Yx axial sealing ring (4), a pipe joint (5), and an O-ring II (6), wherein the O-ring I (2) and the Yx axial sealing ring are arranged on the end surface of the right end of the pressure application joint and at a position of the inner side of the pressure application joint, the O-ring II is arranged at a position of the inner side of the pressure application joint, one end of the pressure application joint is docked with the pipe joint, and the right end of the pressure application joint and the pipe joint are firmly locked through the locknut; and the pressure application joint (1) is divided into a pressure application joint with one closed end, and a pressure application joint with one threaded end. In addition, the pressure application tooling is also provided with a fixing support so as to ensure that workers can operate the tooling conveniently; and the pressure application tooling is pressure-tolerant and leak-free, is high in pulling resistance, can be quickly assembled and disassembled, and is convenient to use.

Description

A kind of tubing stamping tooling

Technical field

The utility model relates to the matching tooling in the industry heat exchanger processes such as the matching tooling in the tubing manufacture process in the materials processing industry and chemical industry, drugs manufacture equipment manufacturing, is a kind of simple and easy tubing hydraulic pressure air pressure dual purpose test tool specifically.

Background technology

In tubing processing and manufacturing process, the tubing after the moulding is carried out air pressure and the hydraulic testing is one of them critical step, be directly connected to the quality of a whole pipe and even the safety and stability of the equipment that this pipe is applied to.In addition, in the industry heat exchanger processes such as chemical industry, drugs manufacture equipment manufacturing, advance promoting the circulation of qi pressure, the hydraulic testing of the heat exchanger tube assembly welding in the heat exchanger also is one of them critical step, is directly connected to whole heat exchange equipment safety and stability.

Traditional approach to tubing air pressure or hydraulic pressure usually by means of complicated cover tubing pressure testing machine, price is more expensive, and virtually increased operation and the cost of upkeep of equipment, in addition, usually exchange the method that heat pipe carries out air pressure and the hydraulic testing and be: the pipe two ends hold out against or are welded with block.Top-closed structure only is adapted to lower pressure, existence is cut operation with weld bond again though the two ends welded type adapts to elevated pressures, the use of two kinds of forms exists respectively that adaptive faculty is low and pressure testing efficient is low, time-consuming takes a lot of work, and is not suitable for especially the work pressure tests of the fast and reliable of hundreds and thousands of pipes of many medium-and-large-sized heat interchanger of amount.

Summary of the invention

The purpose of this utility model is the deficiency that overcomes traditional pressure testing mode, provides a kind of novel easy to be convenient and practical tubing structure for pressure test, i.e. the pipe joint arrangement of tubing pressure testing.

Technical solutions of the utility model are: A kind of tubing stamping tooling,Comprise and suppress joint 1, O-ring seals I 2, set nut 3, Yx axial sealing ring 4, pipe adapter 5, O-ring seals II 6, O-ring seals I 2 and Yx axial sealing ring pack into the end face of suppressing the joint right-hand member with suppress the joint inner side, the O-ring seals II pipe adapter inner side of packing into, suppress joint and dock with pipe adapter, will be suppressed right-hand member and the pipe adapter locking of joint by set nut.Wherein suppress the joint other end and be closed or the end screw-type, two each other a cover seal respectively pipe two, the end that screw thread picks out is in order to connect valve or water nozzle.Different size according to pipe can match with it with the stamping tooling of dimension.

Be provided with fixed support, fixed support comprises that fixed beam 8, fixed block 9, hex bolts I 10, perpendicular version 11 and pipe clamp 12 consist of; Perpendicular version and pipe clamp are connected on the fixed beam by hex bolts, and stamping tooling is contained on the pipe clamp.

The utility model beneficial effect is: the utility model stamping tooling is detachable, is convenient to install inner Yx axle with O-ring seal and O-ring seals.Whole makes as main material take titanium, greatly alleviated weight, not only lightly but also corrosion-resistant, do not worry using or leaving unused for a long time and get rusty and even scrap for a long time.In addition, this stamping tooling also is furnished with fixed support to make things convenient for the workman to operate, and fixed support comprises fixed beam, fixed block, hex bolts I, hex bolts II, perpendicular version, as being used for water pressure generation, also can be equipped with leg support.

The utility model is withstand voltage, without leak, that tension is taken off ability is strong, fills, tears open rapidly, easy to use.

Suppress joint 1, O-ring seals I 2, set nut 3, Yx axial sealing ring 4, pipe adapter 5, O-ring seals II 6, the support 7 of beam, fixed beam 8, fixed block 9, hex bolts I 10, hex bolts web member 11, perpendicular version 12, leg support 13.

Embodiment

Using method of the present utility model is as follows:

At first choose the stamping tooling of appropriate size according to the pipe specification, such as the need air pressure, then need be equipped with fixed support, such as the need water pressure generation, then on the support bracket fastened basis of outfit, also should be equipped with leg support.

When doing gas pressure test, at first fixed support is sunk in the tank, the workman divides and is seated at pipe two, and a termination gas is enclosed within respectively pipe two with stamping tooling, firmly hold out against, make pipe end head into the inner Yx axle of frock O-ring seal lip, reach the effect of abundant sealing, then immerse tank, suppress the U-lag that joint snaps in the tank inner fixed support, fix and namely finish the whole step of suppressing.

When doing the hydraulic testing, at first fixed support is fixed by bolts on the leg support, fill a pipe clamp assembly every a segment distance on the fixed support, unclamp the pipe clamp assembly nut, pipe is penetrated by the centre, stamping tooling is loaded onto at two, put into again support bracket fastened U-lag, tight pipe clamp assembly top nut, strike tight two U-lag base, pipe is completely fixed extremely, then enter water nozzle by a termination, the beginning water pressure generation, wait be raised to relevant pressure and hunt leak complete after, unclamp pipe and repeat again above-mentioned steps, suppress next root pipe.
