Abstract
The utility model relates to the technical field of a heat exchanger pressure test device and particularly relates to a novel floating head heat exchanger pressure test tool. The novel floating head heat exchanger pressure test tool comprises a pressure cover, a bolt, a nut, a sealing ring sleeve, a sealing ring, a short circuit part, a connection tube, a tube cap, a flange and a connection lug, wherein the pressure cover is connected with the sealing ring sleeve through the nut, one end of the nut is provided with the bolt, a bottom portion of the sealing ring sleeve is provided with the sealing ring, a top end of the sealing ring sleeve is provided with the connection tube, the connection tube is connected with the tube cap, one end of the sealing ring sleeve is connected with the flange through short circuit part, and the flange is provided with the connection lug. According to the novel floating head heat exchanger pressure test tool, by employing the automatic-contact-force-compensation contact sealing technology and the adjustable structure technology, the pressure test tool can solves a problem that a traditional floating head heat exchanger pressure test tool has a single model and requires two heat exchanger in matching with two pressure test tools and further solves problems of poor sealing effect, long pressure test time and inconvenient mounting in the test tool in the prior art, heat exchangers having equal nominal diameters and different pressure grades can utilize one same test tool, so the novel floating head heat exchanger pressure test tool has excellent practical values.
Description
Technical field
The utility model relates to heat interchanger pressure testing device technical field, refers in particular to a kind of novel float head heat-exchanger pressure test tool.
Background technology
Because heat exchanger core and the housing of movable tube sheets heat exchanger floating end are open form, do not form the cavity of sealing holding liquid, a special pressure test tool must be installed when pressure testing makes it airtight, in the past in movable tube sheets heat exchanger work pressure test, the structure for pressure test adopting is steel components, size is larger, difficulty is installed, and because hermetically-sealed construction exists defect, sealing effectiveness is undesirable, in movable tube sheets heat exchanger maintenance process, the most of the time that almost accounts for whole heat interchanger maintenance process due to pressure testing process, so the performance quality of heat interchanger structure for pressure test will directly affect pressure testing efficiency, existing pressure test tool also exists sealing effectiveness poor, the pressure testing time is long, the defects such as not convenient are installed.
Therefore, design pressure testing good sealing effect for overcoming the deficiency of above-mentioned technology, the pressure testing time is short, and a kind of novel float head heat-exchanger pressure test tool, just inventor's problem to be solved are easily installed.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel float head heat-exchanger pressure test tool, and it is simple in structure, easy to use, pressure testing good sealing effect, and the pressure testing time is short, and it is convenient to install, and has extraordinary practical value.
The utility model solves the technical scheme that its technical matters adopts: a kind of novel float head heat-exchanger pressure test tool, it is characterized in that: frock comprises gland, bolt, nut, seal ring set, O-ring seal, short circuit, adapter, pipe cap, flange, connection journal stirrup, gland is connected with seal ring set by nut, nut one end is provided with bolt, seal ring set bottom is provided with O-ring seal, seal ring set top is provided with adapter, take over and be connected with pipe cap, seal ring set one end is connected with flange by short circuit, is provided with connection journal stirrup on flange.
The utility model is compared and is had obvious advantage and beneficial effect in prior art, particularly, and as shown from the above technical solution:
1, the utility model is by adopting contact Sealing Technology and the adjustable structure technology of contact force auto-compensation, pressure test tool can overcome the problem that single and two heat interchanger of traditional movable tube sheets heat exchanger pressure test tool model are joined two pressure test tools, solved pressure test tool sealing effectiveness poor simultaneously, the pressure testing time is long, the defects such as not convenient are installed, the effect that the general pressure test tool of nominal diameter different pressures grade heat interchanger such as reaches, has extraordinary practical value.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Accompanying drawing explanation: 1-gland; 2-bolt; 3-nut; 4-seal ring set; 5-O-ring seal; 6-short circuit; 7-takes over; 8-pipe cap; 9-flange; 10-connects journal stirrup.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 is a kind of novel float head heat-exchanger pressure test tool structural representation of the utility model, frock comprises gland 1, bolt 2, nut 3, seal ring set 4, O-ring seal 5, short circuit 6, adapter 7, pipe cap 8, flange 9, connects journal stirrup 10, gland 1 is connected with seal ring set 4 by nut 3, nut 3 one end are provided with bolt 2, seal ring set 4 bottoms are provided with O-ring seal 5, seal ring set 4 tops are provided with takes over 7, taking over 7 is connected with pipe cap 8, seal ring set 4 one end are connected with flange 9 by short circuit 6, be provided with and connect journal stirrup 10 on flange 9.
The gland 1 of the utility model structure for pressure test employing activity, with the flange arrangement of movable tube sheets heat exchanger connecting portion employing seal boss band tongue-and-groove, object is to guarantee sealing and certain intensity, prevents compressive deformation; Adopt the moving of gap to coordinate with floating tube sheet connecting portion, seal ring set width, object is reduce distortion and realize tube sheet depth adjustment.Between joint flange and seal ring set 4, be connected with rolling cylinder, with weight reduction, reduce difficulty of processing, structure for pressure test main body adopts bolt 2 to be connected with gland 1, structure for pressure test hermetically-sealed construction, for the design feature of movable tube sheets heat exchanger, adopts the structure for pressure test with the O-ring seal 5 of O type.O-ring seal 5 self-tightening sealings of O type, required pretightning force is little, and therefore sealing property is better; The O-ring seal 5 of O type seals and compares with C type with packing, and O type ring can repeatedly use and be with low cost.
The utility model is by the float head heat-exchanger pressure test tool of new structure, heat interchanger pressure test tool can overcome the problem that single and two heat interchanger of traditional movable tube sheets heat exchanger pressure test tool model are joined two pressure test tools, solved pressure test tool sealing effectiveness poor simultaneously, the pressure testing time is long, the defects such as not convenient are installed, the effect that the general pressure test tool of nominal diameter different pressures grade heat interchanger such as reaches, has extraordinary practical value.
