Abstract
A kind of water pressure test special flange lid, including blind flange body；Mounting hole, the mounting hole are arranged on the blind flange body, and one end of connecting tube is arranged in the mounting hole；The diameter of wherein described mounting hole is bigger 1 millimeter than the external diameter of the connecting tube；The distance L at the center of the mounting hole and the center of the blind flange body=（Φ1‑ΦA）/2；Wherein, Φ 1 is the diameter of heat exchanger corner apertures bushing, and Φ A are the diameter of the mounting hole.The utility model water pressure test special flange is covered in water pressure test water filling, can be by maximizing the air discharge rate inside heat exchanger in the connecting tube close to blind flange upper part.So so that residual quantity of the air inside heat exchanger minimizes, and in pressure maintaining period, its pressure no longer declines because of residual air；Also, because air residual quantity very little, the damage of rubber cushion is also minimum, improves water pressure test percent of pass to a certain extent, improves the quality of heat exchanger.
Description
Technical field
Mechanical field, more particularly to hot swapping are the utility model is related to, particularly a kind of hydraulic pressure of plate type heat exchanger
Test special flange lid.
Background technology
At present, the blind flange used in the water pressure test, from blind flange center spud, then pressure gauge is connect；In the water pressure test
Cheng Zhong, when institute's water injection rate covers the adapter, adapter mouth will form fluid-tight, and the air inside heat exchanger can not will discharge again；It is residual
The air stayed in inside heat exchanger is more, and pressure decline is may result in pressurize；Separately because rubber cushion is to gas seal property
It is poor, rubber cushion may be damaged so that heat exchanger water pressure test percent of pass reduces, and reduces the quality of heat exchanger.
Utility model content
The purpose of this utility model is to provide a kind of water pressure test special flange lid less to rubber cushion damage.
In order to solve the above technical problems, the utility model water pressure test special flange lid, including blind flange body；Installation
Hole, the mounting hole are arranged on the blind flange body, and one end of connecting tube is arranged in the mounting hole；Wherein described peace
The diameter for filling hole is bigger 1 millimeter than the external diameter of the connecting tube；The center of the mounting hole and the center of the blind flange body
Distance L=（Φ1-ΦA）/2；Wherein, Φ 1 is the diameter of heat exchanger corner apertures bushing, and Φ A are the diameter of the mounting hole.
The bolt hole of two or more number is provided with the blind flange body, the bolt hole of two or more number encloses
It is evenly arranged around the center of the blind flange body.
The utility model water pressure test special flange is covered in water pressure test water filling, can be by close to blind flange upper part
Connecting tube by inside heat exchanger air discharge rate maximize.So so that residual quantity of the air inside heat exchanger is minimum
Change, in pressure maintaining period, its pressure no longer declines because of residual air；Also, because air residual quantity very little, the damage of rubber cushion
Wound is also minimum, improves water pressure test percent of pass to a certain extent, improves the quality of heat exchanger.
Brief description of the drawings
Fig. 1 is the utility model water pressure test special flange lid structural representation；
Fig. 2 is Fig. 1 B-B sectional views.
Embodiment
The utility model water pressure test special flange lid is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model water pressure test special flange lid, including blind flange body 1；Mounting hole 2, peace
Dress hole 2 is arranged on blind flange body 1, and one end of connecting tube is arranged in mounting hole 2；Wherein the diameter of mounting hole 2 is than connection
The external diameter of pipe it is big 1 millimeter；The distance L at the center of mounting hole 2 and the center of blind flange body 1=（Φ1-ΦA）/2；Wherein, Φ
1 is the diameter of heat exchanger corner apertures bushing, and Φ A are the diameter of mounting hole 2.
The bolt hole 3 of two or more number is provided with blind flange body 1, the bolt hole 3 of two or more number surrounds method
The center of blue lid body 1 is evenly arranged.
The utility model water pressure test special flange is covered in water pressure test water filling, can be by close to blind flange upper part
Connecting tube by inside heat exchanger air discharge rate maximize.So so that residual quantity of the air inside heat exchanger is minimum
Change, in pressure maintaining period, its pressure no longer declines because of residual air；Also, because air residual quantity very little, the damage of rubber cushion
Wound is also minimum, improves water pressure test percent of pass to a certain extent, improves the quality of heat exchanger.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is limited to the embodiment, those skilled in the art can also make on the premise of without prejudice to the utility model creative spirit
A variety of equivalent modifications or replacement, these equivalent modifications or replacement are all contained in the application claim limited range
It is interior.
