Abstract
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 action pressure-testing joint, for heat exchanger pressure testing is used.
Technical background
Heat exchanger is owing to needing the pressure bearing intrasystem oil, gas, water etc., so need in the fabrication process to carry out pressure test to product, the inside cavity of heat exchanger can pour pressurized gas and measure.Because gas pressure is larger, again because more dangerous in operation, so may there is joint, adapter waits the danger of plug explosion.Therefore a kind of special frock is needed to solve this problem.
Summary of the invention
In order to solve the above problem, the invention provides a kind of explosion-proof action pressure-testing joint, for preventing in heat exchanger pressure testing process, may burst at pipe joint place, this joint can clamp heat exchange manifold, chuck strength, higher than general securing means, makes heat exchanger can be safer in the process of pressure testing, and can release pressure.
For solving above technical problem, the invention provides following technological scheme: a kind of explosion-proof action pressure-testing joint, this joint is used for for 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, one end open, and have elasticity during this opening end barrel both sides hand, Tube Sheet of Heat Exchanger connects this opening end by blast ring;
Have hole in the middle of described sealing gasket, this hole communicates with described Tube Sheet of Heat Exchanger, and sealing gasket top set is in heat exchanger mouth of pipe end;
Described gland top set is in sealing gasket place, and centre has hole, and communicate with sealing pad holes, and communicate with air, both sides have the structure of bulging steel basket barrel, and steel basket barrel can strut by this structure.
Further, the one end open of described steel basket, the other end is the supporting base of semi-enclosed fixing barrel, and barrel is opening barrel, and this barrel is made up of the blade of several circumferential arrangements, has the gap that can make 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 blade inwall has domatic projection.
Further, the opening end of described steel basket has clamping pressure ring, and after opening end connects blast ring, this clamping pressure ring rises
Increase fastening effect; This open end is also provided with outside projection, prevents blast ring generation vibration.
Further, described gland is T-shaped structure, and crossbar sections has shoulder side slope, and this domatic and domatic projection matches, and for bulging steel basket barrel, lever part has screw thread, and this screw thread is for connecting steel basket supporting base.
Further, have square handle bottom described gland vertical pole, square handle place has tapped hole, and square handle is convenient to rotary gland.
This explosion-proof action pressure-testing joint that the present invention relates to, structure is simple, can effectively address the deficiencies of the prior art, and the clamping force of this joint and Tube Sheet of Heat Exchanger, higher than general joint, is placed on the excessive joint explosion caused of pressure in heat exchanger pressure testing process.
