Abstract

A special tool for installing a blowback valve belongs to the technical field of coal gasification equipment. The tool comprises a split nut, transverse plates and an ejector rod screw, the aperture of a screw hole in the middle of the split nut is matched with the outer diameter of a corrugated pipe in the blowback valve, the transverse plates are symmetrically and transversely fixed to the outer side of the split nut, the split nut is opened, closed and fixed through a transversely-through fastening screw, and the ejector rod screw is vertically arranged at the end, close to the split nut, of each transverse plate in a penetrating mode. Double nuts are arranged on the upper side and the lower side of the transverse plate to fix the ejector rod screw. The tool is convenient to machine and use, and can play a role in protecting equipment parts so as to achieve the purposes that the equipment parts are not damaged during overhauling and can be repeatedly used for multiple times.

Description

TECHNICAL FIELD

[0001] The utility model belongs to coal gasification equipment technical field, specifically relates to a special tool for installing back blow valve. BACKGROUND

[0002] Coal gasification S1501 back blow valve is important equipment of coal chemical industry device, is expensive, when maintaining and installing back blow valve, the control of installation size, inclination and valve stroke requirement are extremely high when installing corrugated pipe and cylinder piston disc, once installation is unbalanced or valve core installation is not in place, corrugated pipe is extremely easy to slide or valve core is not closed in place to produce internal leakage in the process of valve use, greatly shorten the service life of corrugated pipe, increase maintenance cost, influence normal production of device. SUMMARY

[0003] The utility model provides a special tool for installing back blow valve, the purpose is in view of the special structure of back blow valve corrugated pipe and cylinder, fixes and adjusts the pre-tightening force of corrugated pipe, prevents the deviation and valve core stroke not in place when installing corrugated pipe.

[0004] A special tool for installing back blow valve, characterized by: including open-close nut, horizontal plate and top rod screw, the hole diameter of the screw hole in the middle of the open-close nut matches the outer diameter of the corrugated pipe in the back blow valve, the horizontal plate is fixed symmetrically transversely on the outside of the open-close nut, the open-close nut is opened and fixed through the fastening screw arranged transversely, the top rod screw is arranged vertically through one end of the horizontal plate close to the open-close nut, and the double nuts on the horizontal plate are arranged to fix the top rod screw.

[0005] Further, the width of the open-close nut is 45mm, the length is 70mm, the height is 20mm, and the hole diameter of the screw hole in the middle is 22mm.

[0006] Further, the diameter of the top rod screw is 12mm, and the length is 120mm.

[0007] Further, the fastening screw is a hexagonal socket head cap screw with a diameter of 8mm.

[0008] The utility model has the advantages that after installing the corrugated pipe, the open-close nut of the tool is used to lock the corrugated pipe, the fastening screw is used for fixation, the double nuts of the top rod screw are adjusted to compress the corrugated pipe to the standard installation height, the cylinder piston disc and the open-close nut of the valve are installed, then the tool is removed, the pre-tightening force of the corrugated pipe is released, and the installation of the valve main part is completed.

[0013] Example 1: A special tool for installing a backwash valve, including open and close nut 1, horizontal plate 2 and top rod screw 3, the width of open and close nut 1 is 45mm, the length is 70mm, the height is 20mm, the middle screw hole diameter is 22mm. Open and close nut 1 is symmetrically fixed horizontally on the outside of horizontal plate 2, open and close nut 1 is opened and fixed by fastening screw 4 which is set horizontally, fastening screw 4 is a 8mm diameter internal hexagonal screw. Top rod screw 3 is vertically set through the end of horizontal plate 2 close to open and close nut 1, the diameter of top rod screw 3 is 12mm, the length is 120mm, and double nuts are set on horizontal plate 2 to fix top rod screw 3.

[0014] After the installation of the corrugated pipe, the open and close nut 1 of the tool is used to lock the corrugated pipe, and the fastening screw 4 is used for fixation. By adjusting the double nuts of top rod screw 3, the corrugated pipe is first adjusted to a vertical state, and then the corrugated pipe is compressed downward to the standard installation height, so that the cylinder piston disc and the fastening valve open and close nut can be installed. After that, the tool is removed, the pre-tightening force of the corrugated pipe is released, and the installation work of the valve main part is completed.
