Technical Field

The invention relates to the technical field of wrench disassembly and assembly, in particular to a multifunctional PE valve wrench.

Background

In the processes of production ventilation replacement and emergency repair, the maintenance and emergency repair team and team can timely, quickly and efficiently close the valve of the PE valve well to cut off the air source, which is the most critical and important work, and the convenient, quick and practical wrench is an essential tool for opening and closing the valve.

At present, a common PE valve wrench is used in an extended version, but the PE valve wrench can only be used for opening a valve reluctantly, but the PE valve wrench is too long in length, so that the PE valve wrench is inconvenient to carry when being maintained by personnel, and an emergency vehicle cannot be carried at any time, so that when an emergency repair accident or ventilation replacement valve opening operation is required, professional maintenance personnel are required to go to a warehouse and pull to an emergency repair site for use, and time is wasted; the PE valve wrench needs to be operated by multiple persons in a matching way, and meanwhile, the valve well is difficult to take out deeply; because of too big self weight, it is comparatively hard when the personnel carry.

In order to change the problems, people start to adopt three sections of steel pipes with the length of 1 meter to be connected by screw threads and insert and fix pins by continuous improvement, and although the PE valve plate solves the problem of difficult carrying, the external wire part of the PE valve plate is easy to damage, so that the PE valve plate cannot be screwed and connected; the pins at the fixed positions are easy to lose; the opening position and the screw thread position cannot be unified, the first section and each subsequent section must be connected according to a specified sequence, otherwise, the pin cannot be inserted.

In summary, we propose a multifunctional PE valve wrench to solve the above problems.

Disclosure of Invention

The invention aims to provide a multifunctional PE valve wrench which is simple to operate and convenient to carry, so that each worker can smoothly and safely complete the work of a switch valve, the time for mounting and dismounting is further reduced, and the working efficiency is improved.

The embodiment of the invention is realized by the following steps:

the utility model provides a multi-functional PE valve spanner, includes handle, wrench end and first rod cover, and above-mentioned handle is equipped with first fourth of the twelve earthly branches piece, and above-mentioned wrench end is equipped with and is used for with the first mortise of above-mentioned first fourth of the twelve earthly branches piece matched with, and above-mentioned first rod cover is used for fixing the connection of above-mentioned first mortise and above-mentioned first fourth of the twelve earthly branches piece.

The first mortise, the first mortise and the first rod sleeve are matched to complete the disassembly and the assembly of the PE valve wrench, so that personnel can carry the PE valve wrench conveniently in the carrying process, the installation and the operation are simpler, smaller parts are abandoned, the problem of loss of parts and accessories is avoided, meanwhile, the exposed thread design is cancelled, and the phenomenon that the PE valve wrench cannot be connected due to thread desalination is prevented; when the personnel go out for maintenance, the PE valve wrench in the embodiment of the invention is used for splitting parts, when the personnel arrive at the site and need to be put into practical use, the first rod sleeve is sleeved from the wrench head, then the first mortise block and the first mortise are butted and installed, finally the handle and the wrench head are fixed by the practical first rod sleeve, and at the moment, the first rod sleeve is arranged at the butt joint of the first mortise block and the first mortise. This design mode operation only need not have specific skill to its first fourth of the twelve earthly branches piece and first tongue-and-groove, also need not carry out the installation of unnecessary part, and first rod cover is great for original pin volume, is difficult for losing relatively speaking more, and installation and dismantlement time all reduce to some extent.

In some embodiments of the present invention, the handle further includes a second rod sleeve having a structure identical to that of the first rod sleeve, an extension rod is disposed between the handle and the plate head, one end of the extension rod is provided with a second mortise, the other end of the extension rod is provided with a second mortise, the first mortise and the second mortise have a structure identical to each other, and the first mortise and the second mortise have a structure identical to each other.

The extension bar is additionally arranged to extend the whole length of the PE valve wrench, so that the operation is more convenient; in addition, the first rod sleeve and the second rod sleeve are universal and practical due to the consistent structure.

In some embodiments of the present invention, the number of the extension bars and the number of the second bar covers are both multiple and correspond to one another.
