The invention provides an explosion-proof pressure testing joint, which is used for testing the pressure of a heat exchanger, wherein the joint comprises an explosion-proof ring, a sealing pad, a steel basket and a pressing cover; the explosion-proof ring is a fastener; the steel basket is of a cylinder-shaped structure with one end formed with an opening; two sides of the cylinder wall of the opening end are elastic when the two sides are pressed by hands, and a heat exchanger pipe is connected with the opening end through the explosion-proof ring; a hole which is communicated with the heat exchanger pipe is formed in the middle of the sealing pad; the sealing pad is arranged at the port end of the heat exchanger pipe; the pressing cover which is formed with a hole in the middle to communicate with the hole of the sealing pad and the atmosphere is arranged on the sealing pad; structures for expanding and pressing the cylinder walls of the steel basket are arranged at two sides of the pressing cover, and the structures can expand the sidewalls of the steel basket. The explosion-proof pressure testing joint is simply structured and is capable of effectively overcoming the shortcomings of the prior art; the clamping force of the joint with the heat exchanger pipe is greater than the clamping force of the normal joint, to prevent the explosion in case of excessive pressure in the process of testing the pressure of the heat exchanger.
Description
Technical field
The present invention relates to a kind of explosion-proof pressure testing joint, for the heat exchanger pressure testing used.
Technical background
Heat exchanger is owing to need bear the pressure of intrasystem oil, gas, water etc., so in manufacture process, need carry out pressure test to product, the inside cavity of heat exchanger can pour pressurized gas and measure.Because gas pressure is bigger, again because of hazardous in operating process, so joint may take place, adapter waits the danger of plug explosion.Therefore need a kind of special frock to solve this problem.
Summary of the invention
In order to solve the above problem; The present invention provides a kind of explosion-proof pressure testing joint, for preventing at the pipe joint place explosion may to take place in the heat exchanger pressure testing process; 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 present invention provides following technological scheme: a kind of explosion-proof pressure testing joint, and this joint is used to the heat exchanger pressure testing, and said joint comprises blast ring, sealing gasket, steel basket and gland;
Said blast ring is a fastening piece;
Said steel basket is a 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 through blast ring;
Have the hole in the middle of the said sealing gasket, this hole communicates with said Tube Sheet of Heat Exchanger, and sealing gasket is put and peaked at heat exchanger mouth of pipe end;
Said gland is put and is peaked at the sealing gasket place, and the centre has the hole, communicate with the sealing gasket hole, and and atmosphere, both sides have the structure of support compressed steel basket barrel, and this structure can strut steel basket sidewall.
Further, an end opening of said steel basket, the other end are the supporting base of semi-enclosed fixedly barrel, and barrel is opening barrel, and this barrel is made up of the blade of several circumferential arrangements, have the slit that can make blade movable between each blade.
Further, have tapped hole in the middle of the supporting base of said steel basket barrel, this tapped hole is used for being connected with gland, and produces relative movement.
Further, said steel basket blade inwall has domatic convexity.
Further, the opening end of said steel basket has the clamping pressure ring, and after opening end connected blast ring, this pressure ring of screwing plays increased fastening effect; This open end also is provided with outside convexity, and it is moving to prevent that blast ring from string taking place.
Further, said gland is a T shape structure, and cross bar partly has the shoulder side slope, and this is domatic to match with the domatic convexity of steel basket, is used to support compressed steel basket barrel, and vertical pole partly has screw thread, and this screw thread is used to connect steel basket supporting base.
Further, said gland vertical pole bottom has square handle, and square handle place has tapped hole, and square handle is convenient to rotate gland.
This explosion-proof pressure testing joint that the present invention 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 pressure in the heat exchanger pressure testing process.
