Abstract
The utility model relates to a leakage testing device of a heat exchanger pipe bundle. The leakage testing device of the heat exchanger pipe bundle is formed by sequentially connecting a gun head, a gun rod, a control valve and a gun tail, wherein the front end of the gun rod is in threaded connection with the gun head; the rear end of the gun rod is in the threaded connection with an outlet of the control valve; an inlet of the control valve is in the threaded connection with the gun tail; the gun rod is communicated with the gun head; the gun rod is further communicated with the control valve; the control valve is further communicated with the gun tail; a pressure gauge seat is mounted on the gun rod and a pressure gauge is mounted on the pressure gauge seat; the front end of the gun head is conical and the rear end of the gun tail is conical; a valve body of the control valve is a cavity; an inlet is arranged at one end of the valve body and an outlet is arranged at the other end of the valve body; the valve body is internally provided with a valve core with a cross-shaped structure; and a gasket is arranged in the middle of the valve core. The leakage testing device disclosed by the utility model can be used for conveniently, rapidly and accurately carrying out leakage-testing and plug-checking detection on the heat exchanger pipe bundle of a petrochemical plant, so that the labor intensity of an operator can be reduced.
Description
Technical field
The utility model belongs to the instrument that the heat exchanging device carries out the leak test detection in the petroleum chemical industry, and what be specifically related to is the heat exchanger tube leakage testing device.
Background technology
Heat interchanger is to use heat-exchange apparatus widely in the petroleum chemical industry, and heat interchanger is the part heat transferred cold fluid with hot fluid, makes fluid temperature (F.T.) reach the exchange heat equipment of technological process set quota, claims heat exchanger again.Heat interchanger is requisite visual plant in the petrochemical unit production run, runs well for guaranteeing petrochemical unit, needs the heat exchanging device to carry out leak test when device annual overhaul or ordinary maintenance and detects.At present, when carrying out the detection of heat exchanger tube leak test, normally with the whole extraction of the tube bank in the heat exchanger shell, restraining two ends orifice plate difference blank off and be connected end socket then, whether water is suppressed in injection, leak to observe to restrain.Also have a kind of way to be, whether the heat interchanger two ends end socket of dismantling exports shell-side blind dead, injects from entrance and to suppress water, observe tube bank and leak.Above leak testing process complicated operation, the leak test DeGrain is especially leaking under the slight situation, more difficult judgement, finds leak source accurately.
Summary of the invention
The purpose of this utility model provides the heat exchanger tube leakage testing device, and this heat exchanger tube leakage testing device is used for solving existing heat exchanger tube leak test detection method complicated operation, the problem that the leak test effect is bad.
The technical scheme that its technical matters that solves the utility model adopts is: this heat exchanger tube leakage testing device is connected and composed successively by rifle head, barral of a gun, operation valve, gun breech, the front end of barral of a gun is connected with the rifle head thread, the rear end of barral of a gun is threaded with the outlet of operation valve, the entrance of operation valve is threaded with gun breech, barral of a gun communicates with the rifle head, barral of a gun also communicates with operation valve, and operation valve also communicates with gun breech; The pressure gauge stand is installed on the barral of a gun, and tensimeter is installed on the pressure gauge stand; It is conical that the front end of rifle head is, and it is conical that the rear end of gun breech also is; The valve inner of operation valve is a cavity, and an end of valve body is entrance, and the other end of valve body is outlet, and the spool of cross structure is installed in the valve body, and there is pad at the spool middle part.
Beneficial effect:
The utility model can carry out leak test convenient, fast to the petrochemical unit heat exchanger tube, exactly and find out and stop detection, can reduce labor intensity of operating personnel, raises labour efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of operation valve in the utility model;
Fig. 3 is the structural representation of spool in the utility model.
10 outlets of 1 rifle head, 2 barrals of a gun, 3 operation valves, 4 gun breeches, 5 pressure gauge stands, 6 tensimeters, 7 spools, 8 pads, 9 entrances.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, this heat exchanger tube leakage testing device is connected and composed successively by rifle head 1, barral of a gun 2, operation valve 3, gun breech 4, the front end of barral of a gun 2 is threaded with rifle head 1, the rear end of barral of a gun 2 is threaded with the outlet of operation valve 3, the entrance of operation valve 3 is threaded with gun breech 4, barral of a gun 2 communicates with rifle head 1, and barral of a gun 2 also communicates with operation valve 3, and operation valve 3 also communicates with gun breech 4; Pressure gauge stand 5 is installed on the barral of a gun 2, and tensimeter 6 is installed on the pressure gauge stand 5.
As Fig. 2, shown in Figure 3, the valve inner of operation valve 3 is a cavity, and an end of valve body is entrance 9, the other end of valve body is for going out 10, the spool 7 of cross structure is installed in the valve body, and there is pad 8 at the spool middle part, when medium enters from entrance, medium pushes up spool 7 from entrance 9, medium can pass through operation valve, when medium from exporting 10 when entering, spool 7 is withstood on the porch, entrance 9 is shut, and medium cannot pass through operation valve.
Rifle head 1 is the nipple that diameter and barral of a gun 2 match, and it is conical that front end is; Barral of a gun 2 is pipe, and gun breech 4 is the nipple that diameter and operation valve 3 match, and it is conical that the rear end of gun breech also is; Outside rifle head 1 and the gun breech 4 variable plug can also be housed, variable plug is made of rubber.
When using the utility model heat exchanging organ pipe bundle leak test to detect, two heat exchanger tube leakage testing devices are inserted the two ends of heat interchanger leak test tube bank respectively, be specially, rifle head sealing with one of them heat exchanger tube leakage testing device, gun breech inserts the tube bank of heat interchanger leak test, the rifle head of another heat exchanger tube leakage testing device inserts the tube bank of heat interchanger leak test, and gun breech 4 connects a flexible pipe, and this flexible pipe is used for the leak test medium is introduced gun breech 4 and entered the heat exchanger tube leakage testing device; Firmly push down barral of a gun 2, when tensimeter 6 is indicated to the leak test pressure of requirement, stop to feed the leak test medium; If two heat exchanger tube leakage testing device pressure are consistent and do not fall for 10 seconds, show then that this pipe does not have to leak, otherwise for leaking, if the pressure of the leakage testing device of heat exchanger tube front is zero, then show the tube bank obstruction.The leak test medium can adopt the fire water in device district.
