Abstract
The utility model discloses a kind of tubular heat exchanger leakage testing device, comprise housing, housing is connected by middle joint flange by long cylinder and short cylinder, long cylinder outer end has small end joint flange, short cylinder outer end has holds joint flange greatly, the large end tube sheet of heat interchanger is connected to outside large end joint flange, small end joint flange inside is the small end tube sheet of heat interchanger, small end joint flange outer end is connected to loose flange, in the middle part of loose flange, there is blind flange, blind flange is connected with small end tube sheet, oval barrel arranges the gingival cyst of mucous gland in the newborn joint with ball valve, each flange connections all arranges Graphite pad formation hermetically-sealed construction.Can be disposable by complete for whole for heat exchanger tube leak test, it is time saving and energy saving to use.
Description
Technical field
The utility model relates to a kind of tubular heat exchanger leakage testing device.
Background technology
If tubular heat exchanger leaks, the tubulation will found out in heat interchanger is which root or which root have crackle and cause dielectric leakage, heat exchanger tube quantity in heat interchanger is a lot (relatively large heat exchanger heat-exchanging tube is more than hundreds of roots), if the leak test that goes wanting one one is very time-consuming.
Summary of the invention
The purpose of this utility model is to provide a kind of tubular heat exchanger leakage testing device, can be disposable by complete for whole for heat exchanger tube leak test, and it is time saving and energy saving to use.
The purpose of this utility model realizes like this, a kind of tubular heat exchanger leakage testing device, comprise housing, housing is connected by middle joint flange by long cylinder and short cylinder, long cylinder outer end has small end joint flange, short cylinder outer end has holds joint flange greatly, the large end tube sheet of heat interchanger is connected to outside large end joint flange, small end joint flange inside is the small end tube sheet of heat interchanger, small end joint flange outer end is connected to loose flange, in the middle part of loose flange, there is blind flange, blind flange is connected with small end tube sheet, oval barrel arranges the gingival cyst of mucous gland in the newborn joint with ball valve, each flange connections all arranges Graphite pad formation hermetically-sealed construction.
When the utility model uses, heat interchanger is positioned in housing, connects.In order to leak test liquid is pressed into from the crack of heat exchanger tube, flow out from large end tube sheet, the opening of heat exchanger tube will be sealed at small end tube sheet place's blind flange and loose flange combination, simultaneously with high-strength graphite gasket by leak test medium-tight in the seal casinghousing be made up of length cylinder and flange, under pressure, just can observe easily is which heat exchanger tube is revealed, do mark, just can change, greatly enhance efficiency like this, can disposable by complete for whole for heat exchanger tube leak test, it be time saving and energy saving to use, save a large amount of working times.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
Embodiment
A kind of tubular heat exchanger leakage testing device, as shown in Figure 1, comprise housing, housing is connected by middle joint flange 9 by long cylinder 8 and short cylinder 10, long cylinder 8 outer end has small end joint flange 7, short cylinder 10 outer end has holds joint flange greatly, the large end tube sheet 11 of heat interchanger is connected to outside large end joint flange, small end joint flange inside is the small end tube sheet 5 of heat interchanger, small end joint flange 7 outer end is connected to loose flange 6, there is in the middle part of loose flange 6 blind flange 3, blind flange 3 is connected with small end tube sheet 5, oval barrel arranges the gingival cyst of mucous gland in the newborn joint 1 with ball valve 2, each flange connections all arranges Graphite pad 4 and forms hermetically-sealed construction.
