Specific implementation mode
Embodiment 1
High-temperature heat-exchanging bidirection press regulating device provided in this embodiment is connected in height by Tube Sheet of Heat Exchanger pipeline joint 5
After warm exhaust gas heat exchanger heat transferring medium heat absorption in the pipeline of outflow end, as shown in Figure 1, including the interior cylindrical portion for setting accommodating cavity,
The inner cavity of cylindrical portion is equipped with the partition board that it is divided into two separate chambers along axis, and partition board is equipped at least two unilaterally connecteds
The one-way cock of two chambers is specially：Pressure-difference valve A and pressure-difference valve B, the cavity bottom close to cylindrical portion bottom are set
Have along the reciprocal reciprocating part of cylindrical portion axis, which is divided into the front chamber 2 of two size dynamic changes with after by reciprocating part
Chamber 3, is equipped with the spring 4 for providing it resilient support between reciprocating part and cavity bottom, the operating pressure of spring 4 is more than unidirectionally
The operating pressure of valve, cylindrical portion bottom are equipped with connection rear chamber and extraneous gas vent.It is radially opened in the outside wall surface of reciprocating part
There is seal channel, in seal channel, the other end of sealing element abuts the internal face of cylindrical portion for one end of sealing element 6.
The operation principle of the product is described as follows：
High-temperature heat-exchanging bidirection press regulating device is connected to by Tube Sheet of Heat Exchanger pipeline joint 5 with heat exchanger tube, normal
Under working condition, the pressure in front chamber 2 and heat exchanger tube is essentially identical or slightly higher, in 4.0-6.0MPa or so, front chamber 2
Volume is 5-8 liters.Pressure-difference valve A and pressure-difference valve B is opened in the case where pressure difference is more than 2MPa, and front chamber compares heat exchanger tube
When the high 2MPa or more of road pressure, pressure-difference valve A is opened, and is released stress from front chamber to heat exchange pipeline, before heat exchange pipeline ratio
When the high 2MPa or more of chamber pressure, pressure-difference valve B is opened, and is released stress from heat exchange pipeline to front chamber.Since heat exchanger exists
In the course of work, the temperature of exhaust gas changes at any time, therefore the pressure in heat exchanger tube is also variation, if do not pressed
Differential regulating valve is controlled, then heat exchanger pressure-regulating device frequently shakes, and influences its service life, and in order to alleviate in time
Heat exchanger pressure, this device are installed on steam side, and inside has partial condensation water, if the not barrier of pressure-difference valve,
Heat exchange efficiency can be reduced, this pressure-difference valve is bidirection press adjustment structure, simple in structure.
Rear chamber is spring buffer structure, and spring starts to compress at a certain pressure, and this product positions 7MPa, rear chamber
It is the important supplement of front chamber, this is also second key component of the present invention, rear chamber and atmosphere, but and front chamber
It is sealed by hard sealing ring, ensures that the liquid of front chamber will not penetrate into rear chamber.
Back cavity building volume size should ensure that heat exchanger in the case that limiting temperature can ensure heat exchanger safe pressure with
Under, it is generally the case that the liquid in heat exchanger tube is no more than 100 liters, when exhaust gas temperature reaches highest limit value, generally requires
Buffering 20% volume, be 15-20 liters, therefore by calculate, should ensure that rear chamber spring-compressed on earth when, can be ante-chamber
Room buffers out maximum 20 liters of volume.
When exhaust gas temperature transfinites（Close to 400 DEG C）, pressure rise in heat exchanger tube at this time, pressure can reach 9-
10MPa, since pressure is more than ante-chamber chamber pressure 2MPa or more in heat exchanger tube, pressure-difference valve B is opened, heat exchanger tube to
Front chamber releases stress, if manifold pressure is 9MPa at this time, front chamber is up to 7MPa.If exhaust gas temperature not under
Drop, then manifold pressure persistently reaches 9MPa or more, then continues to release stress to front chamber, due to the pressure of rear chamber's spring-compressed
Power is 7MPa, then spring starts to compress at this time, is front chamber's cushion space, until heat exchanger tube and front chamber reach pressure difference and put down
It weighs, pressure no longer rises in heat exchanger tube.
It is not continued case that exhaust gas temperature, which transfinites, when exhaust gas temperature is reduced to normal temperature, heat exchanger tube pressure at this time
It is reduced to 5.0MPa or more, since ante-chamber room pressure is 7.0MPa, spring is compressive state.
Ante-chamber room pressure is bigger 2MPa or more than pressure in heat exchanger tube at this time, and pressure-difference valve A is opened, front chamber to
Heat exchanger tube releases stress, and since spring is in compressive state, front chamber keeps pressure in 7.0MPa, until spring is extensive
It is multiple, therefore original heat exchanger tube is buffered to the indoor medium of ante-chamber under pressure difference promotion, is pushed back in heat exchanger tube again,
It ensure that the normal work of heat exchanger.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection domain of the requires of the utility model is all fallen within.
