Abstract
The utility model relates to purging for a gas pipeline, and particularly relates to a purging target plate for a gas pipeline. A built-in purging target plate is installed on a purging pipe, and comprises two parts, namely, a target plate and a target plate sleeve, wherein one end of the target plate sleeve is closed and the other end thereof is provided with a connection flange; the target plate sleeve is provided with nicks along a length direction, and inserted into the purged pipeline along the radial direction of the purging pipe by means of enabling the nicks to face the position of the coming direction of a purging gas; all the nicks of the target plate sleeve are located in the purging pipe; and the purging target plate is arranged in the target plate sleeve, and arranged by means of enabling the nicks of the target plate sleeve to face the coming direction of the purging gas. The purging target plate disclosed by the utility model is simple in material selection and use, low in production difficulty, strong in practicability, high in safety factor, and suitable for purging test for medium pipelines with high temperature, high pressure and large gas pipe diameter.
Description
Technical field
The utility model relates to gas pipeline and purges, and especially gas pipeline is with purging target plate.
Background technology
Carry out in the purge at the gas medium pipeline of constructing complete, at pipe interior the target plate that check purges effect is set.Traditional external target plate need to be arranged on that to purge interim diffusion mouth outside, and it is fixed, if check temperature, pressure, gas medium pipeline that flow velocity is very high, then external target plate need to be made sufficiently solid support.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and provides a kind of gas pipeline with built-in purging target plate.The utility model material selection is simple, and manufacture difficulty is low, and is practical, and safety coefficient is high, be applicable to high temperature, high pressure, medium pipeline that the gas caliber is larger purge test and use.
For addressing the above problem, a kind of gas pipeline is with built-in purging target plate, it is installed on the scavenging duct, it comprises target plate and target plate sleeve, described target plate sleeve one end seals an end and is provided with joint flange, it alongst has breach, and radially insert this jet chimney towards purge gas arriving direction position along described scavenging duct with this breach, described breach all is positioned at scavenging duct, described target plate is arranged in the target plate sleeve, and arranges towards purge gas arriving direction by the breach of target plate sleeve.
Described gas pipeline is with built-in purging target plate, described target plate comprises that an outer internal diameter is less than the sleeve pipe of target plate sleeve diameter, its upper end is provided with the shutoff of blind plate lower end, blind plate is provided with handle, and the flange of being connected with the target plate sleeve connects with bolt, described sleeve pipe and target plate sleeve correspondence have the breach of length direction, and breach is embedded in and is provided with channel-section steel, is provided with the galvanized iron sheet with plank in the channel-section steel.
Described gas pipeline is with built-in purging target plate, described target plate length sleeve is for purging pipe diameter+200mm, and caliber≤1/2 purges pipe diameter, and the breach that dissects along the length sleeve direction is positioned at the sleeve center, length is for being not more than the purging pipe diameter, and width is 1/2 target plate sleeve caliber.
The utility model designs (DN1000＞caliber 〉=DN200) during mainly for the higher gas medium blowing pipeline test of temperature, pressure, flow velocity, built-in target plate is mounted in the test target plate of pipe interior, by on-the-spot practical operation, verify that its test effect is up to standard, and workable, safety coefficient is high.Relatively traditional, the material more simple to the blowing pipeline verifying attachment form of elevated pressures of the utility model popularized, and makes things convenient for installation and removal, can be used repeatedly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model synoptic diagram;
Fig. 2 is described target plate equipment synoptic diagram.
Embodiment
The below comes the utility model is described in detail with manufacturing process of the present utility model:
See also Fig. 1 and Fig. 2, the utility model blowing pipeline mainly is comprised of target plate sleeve 1 and built-in target plate 2 two parts with built-in target plate.
The making of target plate sleeve 1: at first select one section steel pipe, length is for purging pipe diameter+200mm, caliber≤1/2 purges pipeline 3 calibers, dissect along the length sleeve direction, be positioned at the sleeve center, the length of dissecing part must not be greater than purging pipe diameter, and width is 1/2 target plate sleeve, 1 pipe diameter, target plate sleeve 1 one ends weld interim flange 4, one ends and use the steel plate shutoff.The sleeve of having made is run through on the temporary pipeline that closes on diffusion mouth that is welded on the purging pipeline 3.Dissect the arriving direction of partly meeting to purge gas.
The making of target plate 2: sleeve pipe 5 materials that target plate is selected are than the little specification of sleeve pipeline, the making form is consistent with target plate sleeve 1, the size of dissecing according to the target plate sleeve pipe is simultaneously carried out opening, one end welding blind plate 9 and handle, the close channel-section steel of specification 6, plank 7 and galvanized iron sheet 8 are selected in other end shutoff, and galvanized iron sheet is fixed on the plank, subsequently plank and galvanized iron sheet are embedded in the channel-section steel, subsequently with above-mentioned three's the Combination Welding indentation, there at the target plate sleeve pipe 5 that completes.
The pattern that target plate 2 is similar to as " drawer " is inserted in the target plate sleeve 1, is inlaid with galvanized iron sheet 8 one sides and meets arriving direction to purge gas, selects suitable pad, uses bolts to fix blind plate 9 and interim flange 4.
