Description
Technical field
This utility model relates to spanner, particularly to a kind of union spanner.
Background technology
Union is a kind of conduit coupling facilitating installing/dismounting, it is widely used in corrosive liquid conducting pipes, main use during under discharge pipe, intake pipeline, temporary fluid pipeline and other operating mode, the pipeline of conveyance fluid connects, can motionless pipe and by two pipes separately.At present, it is that outer power is tightened onto and seals the most afterwards that known union seals, and under the occasion of high-low pressure test, during operation, ratio is relatively hazardous.
Owing to the three-jaw volume of union is big, so it is relatively difficult with common wrench clamping workpiece, the operating efficiency making installing/dismounting reduces, the instrument that currently available technology is installed, dismounting union uses is iron hammer, but iron hammer is the heaviest, not readily portable, and iron hammer can produce bigger impulsive force to union, cause union fracture or deformation, particularly speedily carry out rescue work scene in blowout, owing to blowout scene is full of natural gas, it is impossible to use hammer union, in order to avoid causing spark to cause the accident expansion, the connection causing pipeline is the most difficult.Therefore it provides the union spanner of a kind of portable construction has important function.
Utility model content
In order to solve, union provision for disengagement of the prior art is excessively heavy, cause union fracture or the problem of deformation, and this utility model provides a kind of union spanner.
In order to solve above-mentioned technical problem, this utility model by the following technical solutions:
A kind of union spanner, including long handle, short handle and pull pawl, one end and the long handle of short handle removably connect, the other end of short handle and pull pawl and removably connect；Pulling pawl is arc component, pulls and arranges the locating slot suitable with union boss on pawl.
Short handle and long handle and short handle use, with pulling pawl, the mode that removably connects, this movable connection method can be that pin connects, can realize short handle and long handle and short handle and pull pawl detachably, for the union of different sizes, that changes different size locating slot pulls pawl；Long handle or the short handle of damage can also be changed.
Because the volume of union is bigger, if pulling pawl to fix the periphery of union, pull pawl and need large-sized setting, of the present utility model pulling arranges the locating slot suitable with union boss on pawl, being arranged such and can avoid pulling pawl and be arranged to large scale, the boss that only need to pull the locating slot of pawl and union is suitable；Additionally, if pulled, the locating slot suitable with boss is only set on pawl, spanner screws the when of unscrewing union, if strength is excessive, it is easily caused the boss fracture of union or deformation so that the dismounting task of union can not complete, and damages union and can increase cost, therefore, pawl of pulling of the present utility model is designed to arcuate structure, while locating slot clasps union boss, pulls pawl and can also agree with very well with the portion perimeter of union.The pawl of pulling of union spanner that this utility model provides is arc component, and arranges on pawl and locating slot that union boss is suitable pulling, can complete union screw unscrew while prevent the fracture of union boss or deformation.
As preferably, if the end of long handle arranges arterial highway gusset.What short handle directly contacted with long handle is that the terminal surface of gusset rather than long handle, long handle and short handle are all not easy to be compromised.
As preferably, the short handle that this utility model provides is with to pull one end that pawl is connected be U-shaped connection post, and the end face of U-shaped connection post is spill, and suitable with the curved end pulling pawl；If using plane contact of the prior art, contact surface straight line discontinuity, cause the unbalance stress pulling between pawl and union, during spanner uses, if mechanical force is very big, short handle and pull pawl serious wear, the union spanner that this utility model provides, the end face of the U-shaped connection post of its short handle and the curved end pulling pawl can well agree with, and while mechanical force can well be transmitted, the degree of wear of spanner is also preferably minimized.
As preferably, the U-shaped connection post of the short handle that this utility model provides arranges one group of through hole.
As preferably, the pawl two side of pulling that this utility model provides arranges two groups of through holes, installs lining in through hole, and the material of lining is different with the material pulling pawl, uses the material such as tin bronze or cast iron to be prepared from；The one of which pulled in the through hole of pawl two side is connected by pin with one group of through hole on U-shaped connection post, according to needs of production, pulls the through hole on pawl two side and suitable one group can be selected to be connected with the U-shaped through hole being connected post；Abrasion in order to avoid equipment, through hole with U-shaped connection post again is installed after lining in the through hole pulled on pawl sidewall be connected, lining uses hard rigid material to be prepared from, be not easy abrasion, it is to avoid pull contact between pawl through hole and short handle through hole and produce abrasion, lining damage after direct more resleeve, short handle need not be changed and pull pawl, while making spanner meet required mechanical strength, save raw materials for production, reduce cost.
This utility model provides a kind of union spanner, this spanner long handle, short handle and pull pawl, and one end and the long handle of short handle removably connect, the other end of short handle and pull pawl and removably connect；Pulling pawl is arc component, pulls and arranges the locating slot suitable with union boss on pawl.This spanner be capable of complete union screw unscrew while prevent union boss fracture or deformation；While making spanner meet required mechanical strength, save raw materials for production, reduce cost；Simple in construction is light and handy, be difficult to infringement, smoothly completes the dismounting task of union.
