Heat exchanger is owing to need to bear the pressure of intrasystem oil, gas, water etc., so need product is carried out pressure test in manufacture process, the inside cavity of heat exchanger can pour pressurized gas and measure.Because gas pressure is larger, because relatively more dangerous in operating process, so joint may occur, adapter waits the danger of plug explosion again.Therefore need a kind of special frock to solve this problem.
The model utility content
In order to solve the above problem, the utility model provides a kind of explosion-proof action pressure-testing joint, for preventing in the heat exchanger pressure testing process, explosion may occur at the pipe joint place, this joint can clamp heat exchange manifold, chuck strength is higher than general securing means, makes the heat exchanger can be safer in the process of pressure testing, and can release pressure.
For solving above technical problem, the utility model provides following technological scheme: a kind of explosion-proof action pressure-testing joint, and this joint is used to the heat exchanger pressure testing, and described joint comprises blast ring, sealing gasket, steel basket and gland;
Described blast ring is a fastening piece;
Described steel basket is tubular structure, and an end opening has elasticity during the hand of this opening end barrel both sides, and Tube Sheet of Heat Exchanger connects this opening end by blast ring;
Have the hole in the middle of the described sealing gasket, this hole communicates with described Tube Sheet of Heat Exchanger, and the sealing gasket top set is in heat exchanger mouth of pipe end;
Described gland top set is in the sealing gasket place, and the centre has the hole, communicates with the sealing gasket hole, and communicates with atmosphere, and both sides have the structure of bulging steel basket barrel, and this structure can strut steel basket sidewall.
Further, an end opening of described steel basket, the other end are the supporting base of semi-enclosed fixedly barrel, and barrel is opening barrel, and this barrel is comprised of the blade of several circumferential arrangements, have the slit that can make the blade activity between each blade.
Further, have tapped hole in the middle of the supporting base of described steel basket barrel, this tapped hole is used for being connected with gland, and produces relative movement.
Further, described steel basket blade inwall has domatic projection.
Further, the opening end of described steel basket has the clamping pressure ring, and after opening end connected blast ring, this clamping pressure ring played the increase fastening effect; This open end also is provided with outside projection, prevents blast ring generation vibration.
Further, described gland is T shape structure, and cross bar partly has the shoulder side slope, and this is domatic to match with the domatic projection of steel basket, is used for bulging steel basket barrel, and vertical pole partly has screw thread, and this screw thread is used for connecting steel basket supporting base.
Further, described gland vertical pole bottom has square handle, and square handle place has tapped hole, and square handle is convenient to rotary gland.
This explosion-proof action pressure-testing joint that the utility model relates to, simple in structure, can effectively address the deficiencies of the prior art, the clamping force of this joint and Tube Sheet of Heat Exchanger is higher than general joint, is placed on the excessive joint explosion that causes of heat exchanger pressure testing course pressure.
