Description

Butt clamp formula check valve dismouting appurtenance

Technical Field

The utility model relates to the technical field of chemical pipeline maintenance, in particular to a butt-clamping type check valve dismounting auxiliary tool.

Background

The opposite clamping check valve is one kind of automatic valve and has the main functions of preventing medium from flowing back, preventing the reverse rotation of the pump and the driving motor, and preventing the medium from leaking from the container. The butt-clip check valve may also be used on a line that supplies auxiliary systems in which the pressure may rise above the system pressure.

In the petrochemical industry field, the butt-clamp type check valve adopts butt-clamp type connection, so that a connecting flange or a threaded pipe, of which two ends are matched with a flange or a threaded pipe on a fluid process pipeline, is omitted, the flange on the fluid process pipeline is directly utilized, the valve body is connected in the fluid process pipeline in a butt-clamp manner through bolts, and meanwhile, a manhole at the top of the valve body is omitted. Therefore, the structure of the check valve is greatly simplified, the processing and the manufacturing are easier, and the overhaul and the assembly are more convenient. However, when the butt-clamp type check valve is installed, because the positions of the pipelines are fixed, workers can hardly put the butt-clamp type check valve between the two flanges, even if the butt-clamp type check valve is successfully put between the two flanges of the pipelines, screw holes on the flanges cannot be accurately positioned, and a great deal of time is wasted for the workers due to continuous adjustment and installation, and the working efficiency is affected; when the butt-clamp type check valve is disassembled, after the fastening bolts on the flange are disassembled, the flanges of the pipelines at the two sides still clamp the butt-clamp type check valve tightly and are difficult to take out, and when the butt-clamp type check valve is forcibly taken out by tools such as a hammer, the butt-clamp type check valve can be damaged.

Detailed Description

For a better understanding of the objects, structures and functions of the present utility model, a further detailed description of an auxiliary tool for assembling and disassembling a clip-on check valve will be provided with reference to the accompanying drawings.

As shown in fig. 1 to 4, an auxiliary tool for dismounting a butt-clamp check valve comprises a support stud 1, wherein an external thread is arranged on the outer side wall of the support stud 1, a hand-held handle 2 is fixedly connected to the middle part of the support stud 1, the hand-held handle 2 is convenient for a worker to hold the auxiliary tool, a support table 7 is fixedly arranged at the lower end of the hand-held handle 2, the whole support table 7 is in a horn shape, extension studs 4 are detachably connected to the left end and the right end of the support stud 1, internal threads are arranged at the inner sides of the left end and the right end of the support stud 1, a connecting stud 3 is fixedly connected to the joint of the extension studs 4 and the support stud 1, external threads are arranged on the outer side wall of the connecting stud 3, the connecting stud 3 is matched with the internal threads of the support stud 1, the extension studs 4 are in threaded connection with the support stud 1 through the connecting stud 3, a threaded hole is formed in the inner side of one end of the extension stud 4 far away from the support stud 1, and the size of the extension stud 4 is matched with the connecting stud 3. The left side and the right side of the support stud 1 are provided with support nuts 5 matched with external threads of the support stud 1, ratchet wrenches 6 are fixedly connected to the outer sides of the support nuts 5, the thickness of the support nuts 5 is larger than that of the ratchet wrenches 6, and the ratchet wrenches 6 control the support nuts 5 to move left and right on the support stud 1.

When the butt-clamp check valve is installed or disassembled, a worker firstly selects whether the lengthening stud 4 is connected according to the distance between the two pipeline flanges, if the distance between the two pipeline flanges is short, the lengthening stud 4 is connected, then the two ends of the lengthening stud 4 are connected with the supporting nuts 5 in a threaded manner, the outer sides of the supporting nuts 5 are aligned with the outer sides of the lengthening stud 4, the lengthening stud 4 is rotated, the distance between the lengthening stud 4 and the supporting stud 1 is adjusted through the connecting stud 3, and the lengths of the supporting stud 1 and the lengthening stud 4 are just clamped between the two pipeline flanges. The staff holds the handle 2 by one hand and rotates the ratchet wrench 6 by the other hand, the supporting nuts 5 in the ratchet wrench 6 move to two sides, and the supporting nuts 5 expand the distance between the end faces of the two pipeline flanges. The worker uses another set of the utility model to prop open the end faces of the flanges of the two pipelines according to the operation. If the two pipeline flanges are not fully spread, a third set of the utility model can be adopted for spreading operation. After the end faces of the two pipeline flanges are completely spread, workers can easily detach or install the butt-clamp check valve.
