Abstract
The utility model provides an underwater airtightness testing device, which comprises a water tank and a flange. The flange is located in the water tank and provided with an air nozzle which is connected with an air tube. The flange is arranged in the water tank and provided with the air nozzle, when a radiant tube needs to be in airtightness testing, the flange in the water tank is hermetically connected with a flange end of the radiant tube, compressed air is filled in the radiant tube via the air tube, if the radiant tube leaks air, bubbles can be generated in the water tank so that the radiant tube can be in airtightness testing accurately and comprehensively, and accordingly reliability of airtightness testing of the radiant tube is improved by the aid of the underwater airtightness testing device.
Description
Technical field
The utility model relates to mechanical hook-up, relates in particular to a kind of device of tightness test under water.
Background technology
At present, in the various heating furnaces that metallurgy and heat treatment industry use, need earlier radiant tube to be heated through combustion gas or resistance wire with various forms of radiant tubes heating furnace temperature, radiant tube is radiated furnace chamber with heat energy again, and then workpiece is heated to the temperature of requirement.Press manufacturing technique requirent, radiant tube must be airtight, and the negative pressure of bearing 0.1MPa.In order to detect the air-tightness of radiant tube, prior art is airtight with the flange end of radiant tube with special tooling usually, in radiant tube, fills the compression air through taking over, and when gauge hand rises to 0.4MPa, sprays or the brushing suds to the radiant tube outside surface.By on can know, carry out air-tightness and detect through on radiant tube, smearing suds in the prior art, occur suds easily and smear inhomogeneous and the situation of omission occurs, cause the reliability that the radiant tube impermeability detects in the prior art lower.
Summary of the invention
The utility model technical matters to be solved is: a kind of device of tightness test under water is provided; Solve the lower defective of reliability that the radiant tube impermeability detects in the prior art, realize the reliability that detects through the radiant tube of tightness test device raising under water impermeability.
The technical scheme that the utility model provides is, a kind of device of tightness test under water comprises water tank and flange, and said flange is arranged in said water tank, and said flange is provided with valve, and said valve is connected with tracheae.
The device of tightness test under water that the utility model provides; Through flange is set in water tank; And flange is provided with valve, and when needs carried out airtight test to radiant tube, the flange in the water tank and the flange end of radiant tube were tightly connected; Pressure gas fills in the radiant tube through tracheae; If radiant tube has the position of gas leakage, then can in water tank, produce bubble and just can accurately comprehensively carry out impermeability and detect, thereby realize having improved the reliability of radiant tube impermeability detection through tightness test device under water to radiant tube.
The aforesaid device of tightness test under water also comprises air compressor, and the gas outlet of said air compressor is connected with said tracheae.
The aforesaid device of tightness test under water supports radiant tube for ease, also is provided with bracing frame in the said water tank.
The aforesaid device of tightness test under water, the said device of tightness test under water comprises a plurality of said flanges.
The aforesaid device of tightness test under water, the top of said water tank is provided with water inlet, and the bottom is provided with water delivering orifice.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do one to the accompanying drawing of required use in embodiment or the description of the Prior Art below introduces simply; Obviously, the accompanying drawing in describing below is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work property, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model structural representation of tightness test device embodiment under water;
Fig. 2 is the utility model working state figure of tightness test device embodiment under water.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the utility model structural representation of tightness test device embodiment under water, and Fig. 2 is the utility model working state figure of tightness test device embodiment under water.As depicted in figs. 1 and 2, present embodiment is the tightness test device under water, comprises water tank 1 and flange 2, and flange 2 is arranged in water tank 1, and flange 2 is provided with valve 21, and valve 21 is connected with tracheae 22.
Particularly, present embodiment tightness test device under water injects water in water tank 1, flange 2 be used to the to be tightly connected flange end 51 of radiant tube 5, and the valve 21 on the flange 2 will be identical in radiant tube 5, just can pressure gas be filled in the radiant tube 5 through tracheae 22.The radiant tube 5 that is full of pressure gas is immersed in the water in the water tank 1, if the place of gas leakage is arranged on the radiant tube 5, just can in water, produce bubble, the testing staff just can comprehensive and accurately carry out impermeability to radiant tube 5 and detect.Wherein, present embodiment tightness test device under water can also comprise air compressor 3, and the gas outlet of air compressor 3 is connected with tracheae 22.The pressure gas that air compressor 3 produces is transported in the radiant tube 55 through tracheae 22.
Further, radiant tube being carried out support radiant tube 5 for ease in the process of air tightness test, can also be provided with bracing frame 4 in the water tank 1.Radiant tube 5 can be placed on bracing frame 4 in the process of carrying out air tightness test, the flange end 51 of being convenient to flange 2 and radiant tube 5 on the one hand is tightly connected, and the opposing party's potbellied is observed the place whether radiant tube 5 has gas leakage in the testing staff.
A nearlyer step, present embodiment tightness test device under water can comprise a plurality of flanges 2, can realize that through a plurality of flanges 2 are set in water tank 1 simultaneously a plurality of radiant tubes 5 being carried out impermeability detects.In addition, the top of the water tank 1 in the present embodiment can be provided with water inlet 11, and the bottom can be provided with water delivering orifice 12.Can easily water be injected in the water tank 1 through water inlet 11, and water delivering orifice 12 can be easily with the water emptying in the water tank 1.
Present embodiment is the tightness test device under water; Through flange is set in water tank; And flange is provided with valve, and when needs carried out airtight test to radiant tube, the flange in the water tank and the flange end of radiant tube were tightly connected; Pressure gas fills in the radiant tube through tracheae; If radiant tube has the position of gas leakage, then can in water tank, produce bubble and just can accurately comprehensively carry out impermeability and detect, thereby realize having improved the reliability of radiant tube impermeability detection through tightness test device under water to radiant tube.
