Abstract

The utility model belongs to the technical field of hydraulic means makes and specifically relates to a welding formula float tube connects, including a floating sleeve, this floating sleeve both sides tip do not sets up to stiff end and free end, the stiff end of floating sleeve and an oil pipe's tip welding are fixed, and the free end inner edge cartridge of this floating sleeve has a side end that floats the core, and should float the opposite side tip of core and wait with another that the oil pipe tip welding who is connected was fixed, an annular groove is made along the inner edge to the floating sleeve free end, the embedded outer ends who is equipped with a sealing washer of this annular groove, the inboard tip of this sealing washer and the superficial core outer fringe in close contact with who stretches into the floating sleeve, superficial core outer fringe cover between sealing washer and the floating sleeve free end is equipped with a guide ring, the outer fringe of this guide ring with the inner edge of floating sleeve inlays the dress mutually, the preceding terminal surface of sealing washer to the distance of floating the core chamfer be greater than connect oil pipe's harmomegathus volume.

Description

A kind of welding type float shoe

Technical field

This utility model is related to hydraulic means and manufactures field, especially a kind of welding type float shoe.

Background technology

Joint be hydraulic test pipeline arrangement one of significant components, its major function be by the bodys such as oil pipe and other Equipment connects, or the transition between body connects.Common pipe joint is arranged on Long travel pipeline, difference variation is larger or shakes During dynamic frequently region, affected because pipe fitting the factor such as is acted on by thermal expansion or external force, the axial dimension of oil pipe can be sent out Raw change, will produce stress to rigidly connected pipe joint therewith, this stress can cause not to the service behaviour of pipe joint Good impact, in some instances it may even be possible to lead to pipe fitting and the connection of pipe joint to be destroyed, leaks.

For the problems referred to above, common solution is that straight pipeline is deliberately bent one end, forms telescopic joint, works as pipe When line is acted on by thermal expansion or external force, the axial dimension change major part of pipe fitting is absorbed by telescopic joint, so to pipe joint Impact just substantially reduces.

But following shortcoming is had using above-mentioned solution: 1. the telescopic joint of pipeline not only increases pipe fitting This, also increase processing and the installation difficulty of pipe fitting；2. the telescopic joint of pipe fitting affects the attractive in appearance of pipeline；3. the telescopic joint of pipeline Stress can be reduced, but can not eliminate stress, if telescopic joint can not fully absorb stress, still pipeline can be caused with bad shadow Ring.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, absorption stress, sealing A kind of strong clevis mounting cylinder displacement transducer mounting structure of property.

This utility model adopts the technical scheme that:

A kind of welding type float shoe it is characterised in that: include an empty boasting, this empty boasting both side ends is set to solid respectively Fixed end and free end, the fixing end of described empty boasting is welded and fixed with the end of an oil pipe, and the free end inner edge of this empty boasting is fitted with One side end of one floating core, the end side of this floating core is welded and fixed with another oil pipe end to be connected, and described empty boasting is certainly One ring annular groove is made along inner edge by end, in this annular groove, is embedded with the outboard end of a sealing ring, this sealing ring interior Side end is in close contact with the floating core outer rim stretching into empty boasting.

And, the floating core outer rim between described sealing ring and empty boasting free end is set with a guide ring, outside this guide ring Edge is embedded in the inner edge phase of described empty boasting.

And, the front end face of described sealing ring is more than the harmomegathus amount of institute's connected pipes to the distance floating core chamfering.

Advantage of the present utility model and good effect are:

In this utility model, a side end of the fixing end of described empty boasting and floating core respectively with two oil pipe ends to be connected It is welded and fixed the assembling axiality it is ensured that between pipe joint and oil pipe, the sealing ring installed between floating core and empty boasting, can be effective Intercept fluid it is ensured that fluid does not flow out in the gap between empty boasting and floating core, between empty boasting and floating core, two can be ensured with guide ring The assembling axiality of person, during guaranteeing that empty boasting and floating core occur relative displacement, stable movement；The front end face of sealing ring falls to floating core The harmomegathus amount that the distance at angle is more than institute's connected pipes can ensure, in the course of the work, sealing ring is without departing from sealing surface, thus inhaling Receive stress, harmful effect pipeline being caused because of factors such as temperature change, external force effect and vibration effects of preventing.

Brief description

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

Specific embodiment

With reference to embodiment, this utility model is further illustrated, following embodiments are illustrative, be not limited It is impossible to limit protection domain of the present utility model with following embodiments.

A kind of welding type float shoe, innovation of the present utility model is, including an empty boasting 2, this empty boasting both side ends It is respectively set to fixing end and free end, the fixing end of described empty boasting is welded and fixed with the end of an oil pipe 1, the freedom of this empty boasting End inner edge is fitted with a side end of a floating core 5, and the end side of this floating core is solid with another oil pipe 6 end welding to be connected Fixed, described empty boasting free end makes a ring annular groove 7 along inner edge, is embedded with the outboard end of a sealing ring 3 in this annular groove Portion, the medial end of this sealing ring is in close contact with the floating core outer rim stretching into empty boasting, and the front end face of described sealing ring falls to floating core The distance at angle 8 is more than the harmomegathus amount of institute's connected pipes.

In this enforcement, the floating core outer rim between described sealing ring and empty boasting free end is set with a guide ring 4, this guide ring Outer rim and described empty boasting inner edge phase setting-in.

Work process of the present utility model is:

When this utility model uses, oil pipe end to be connected with two respectively for welding type float shoe is welded by operator Connect fixation, when the axial dimension of oil pipe can change, floating core can along empty boasting outer rim to free end one side shifting, but due to Sealing ring is inlaid in inside empty boasting, and therefore it is still in close contact, with floating core outer rim, the leakage that fluid will not occur, and can inhale simultaneously Receive the stress in axial direction.

Claims

1. a kind of welding type float shoe it is characterised in that: include an empty boasting, this empty boasting both side ends respectively be set to fix End and free end, the fixing end of described empty boasting is welded and fixed with the end of an oil pipe, and the free end inner edge of this empty boasting is fitted with one One side end of floating core, the end side of this floating core is welded and fixed with another oil pipe end to be connected, and described empty boasting is freely A ring annular groove is made along inner edge in end, is embedded with the outboard end of a sealing ring, the inner side of this sealing ring in this annular groove End is in close contact with the floating core outer rim stretching into empty boasting.
