Technical field:
The utility model relates to and is used to detect that pressure-resistant pipeline is withstand voltage, the device of sealing property, more particularly especially a kind of quick pressure testing device that is used for the performances such as withstand voltage and sealing of detected pressures container heat exchanger tube.
Background technology:
In the manufacture process of pressure vessel, before the exchange heat pipe assembly welding, exchange heat pipe usually and pursue root pressure testing detection, could use after pressure testing is qualified, to guarantee the quality and the production work efficiency of pressure vessel.Heat exchanger tube is a pipe that seals, and exchanges the method that heat pipe carries out pressure testing at present to be, the mouth of pipe of heat exchanger tube opening is welded on the connector of pressure testing equipment, and pressure testing equipment injects gases at high pressure or water under high pressure in pipe, prescind after pressure testing is finished again.This pressure testing mode is time-consuming, effort and work efficiency are low.
Summary of the invention:
The utility model is to be the quick pressure testing device of avoiding above-mentioned existing in prior technology weak point, provide a kind of saving time, pipeline is detected in the labour-saving.
Design feature of the present utility model is to constitute L type fixed mount by a riser and a flat board, and the riser of fixed mount is provided with the packoff that is used to seal the heat exchanger tube mouth of pipe; Packoff constitutes by sealing screw rod and sealing slide block, and wherein, the riser of sealing screw rod and fixed mount seals the front end that slide block is positioned at the sealing screw rod to be threaded, and sealing slide block is the column staving of droping to the ground, and it is provided with the pressure source input hole that connects pressure source; The flat board of fixed mount is provided with the hold down gag that is used to compress heat exchanger tube.
Design feature of the present utility model also is:
Hold down gag is made of clam member, clamping frame and clamping screw, wherein, clamping frame and fixed mount dull and stereotyped affixed, clamping frame and clamping screw are threaded, the lower end loose joint clam member of clamping screw.
In sealing the sidewall of slide block, tensimeter is set.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Using the utility model is after heat exchanger tube with pressure testing is placed on the fixed mount, easily it to be fastened on the fixed mount rapidly by hold down gag, easily the mouth of pipe is sealed with packoff again, can begin pressure testing.Operating process is simple, has improved work efficiency greatly, has saved time and expense.
