Abstract
The utility model relates to a pressure testing device, in particular to a pressure testing device for a single component of a water cooled wall of a blast furnace suitable for metallurgical industry. The pressure testing device comprises a jackscrew connected with a pressure testing instrument system and provided with a central through hole, and a sleeve connected with a pressure testing pipeline, wherein the jackscrew and the central through hole of an end cover of the sleeve are in threaded connection; the sleeve is sleeved on a mouth of the pressure testing pipeline through a bolt ejector rod on the wall of the sleeve; and the bottom end face of the jackscrew is compressed on the mouth of the pressure testing pipeline sequentially through a gland and a wear-resistant and pressure-resistant sealing gasket arranged in the sleeve. The pressure testing device is convenient to assemble and disassemble during the pressure test; a plurality of sets of the pressure testing devices can be connected in series; the pressure testing efficiency is obviously improved; the machining cost of respective components constituting the device is low, and the comprehensive utilization ratio and practical field recycling rate are high; the device has less wear; and proper protective oil can be coated on the device for storage after use.
Description
Technical field
The utility model relates to pressure testing device, specifically is a kind of blast furnace water-cooling wall monomer members pressure testing device that is applicable to metallurgy industry.
Background technique
Need to carry out the monomer pressure testing after cooling equipments such as metallurgy industry blast furnace are marched into the arena, traditional pressure testing mode is loaded down with trivial details relatively, and it is bigger to drop into human and material resources.And the material after each use once, how all can't use for the second time, recycling rate of waterused is low, causes waste.
Summary of the invention
The utility model is intended to solve the problems referred to above that traditional pressure testing mode exists, and provide a kind of simple in structure, be convenient to install, can improve the blast furnace water-cooling wall monomer members pressure testing device of pressure testing material recycling rate of waterused.
The technological scheme that the described problem that solves the utility model adopts is: a kind of blast furnace water-cooling wall monomer members pressure testing device, comprise a jackscrew that connects the pressure testing instrument system, has central through bore, a sleeve pipe that connects the pressure testing pipeline, described jackscrew is threaded with described sleeve pipe end cap central through bore, this sleeve pipe is contained on the pressure testing pipeline opening by the bolt top stem casing on its tube wall, and this jackscrew bottom end is successively by placing gland and wear-resisting pressure-resistant seal pad in this sleeve pipe to be pressed on this pressure testing pipeline opening.
Compared with prior art, the loading and unloading facility can be organized series connection more during the utility model pressure testing, and pressure testing efficient obviously improves; Each member processing cost of component devices is low, and comprehensive utilization ratio and on-the-spot actual recycling rate of waterused be high, and the device wearing and tearing are little, finishes using can be coated with due care oil and deposit.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the jackscrew structural representation.
Among the figure: jackscrew 1, gland 2, sleeve pipe 3, pressure testing pipeline 4, bolt push rod 5, wear-resisting pressure- resistant seal pad 6 and 7, wear-resistant seal pad 8, high pressure rubber pipe joint 9, planar slot 10, axial central through hole 11.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2, its jackscrew 1 of the pressure testing device of present embodiment is added by common bar machine and forms, top is processed with high pressure rubber pipe joint 9 that connects the pressure testing instrument system and the planar slot 10 that is used to tighten, the bottom surface is a working surface, being used as when turning planar slot 10 makes jackscrew 1 hold out against gland 2 downwards, outer rim is processed with outside thread, and the centre is processed with axial central through hole 11.The common weldless tube blank off of its sleeve pipe 3 usefulness end cap is welded, and the end cap center is processed with interior threaded hole, and circumference is even on sleeve pipe 3 outer walls is furnished with three bolt push rods 5.
During use, sleeve pipe 3 is sleeved on the oral area of pressure testing pipeline 4, and turn bolt push rod 5 holds out against pressure testing pipeline 4.Jackscrew 1 passes sleeve pipe 3 end cap central through bores and is threaded with sleeve pipe 3, and both surface of contact are equipped with wear-resistant seal pad 8, to seal and to protect both screw threads.Set gradually wear-resisting pressure-resistant seal pad 7, gland 2 and wear-resisting pressure-resistant seal pad 6 between 4 mouthfuls in jackscrew 1 bottom surface and the pressure testing pipeline, when the planar slot 10 by jackscrew 1 turned jackscrew 1, jackscrew 1 bottom surface then was pressed on wear-resisting pressure-resistant seal pad 7, gland 2 and wear-resisting pressure-resistant seal pad 6 downwards on the mouth of pressure testing pipeline 4.After fixing this pressure testing device, carry out pressure testing by the high pressure rubber pipe joint 9 on jackscrew 1 top and the pressure gauge of high-pressure rubber hose connection pressure testing system etc.
