In order to which technical characteristic, purpose and effect to the present invention are more clearly understood from, now compare accompanying drawing and describe in detail
The embodiment of the present invention.
As shown in figure 1, the plate type heat exchanger of one embodiment of the invention suppresses test device, including panel seat 10, it is arranged on
Water inlet 20, exhaust outlet 30 and pressure gauge 40 on panel seat 10.Panel seat 10 is used to be arranged on plate type heat exchanger, water inlet 20
For the water-filling into plate type heat exchanger, exhaust outlet 30 is vented for plate type heat exchanger, and pressure gauge 40 is used to detect plate type heat exchanger
Internal pressure.
Wherein, the access port of the correspondence of panel seat 10 plate type heat exchanger is set, that can be sealed on access port.The present embodiment
In, panel seat 10 is circular slab, is made of steel, and intensity is high.
Panel seat 10 is provided with the connecting hole 11 worn for fastener, and connecting hole 11 and plate are screwed onto by fasteners such as bolts
On formula heat exchanger, panel seat 10 is fixed on plate type heat exchanger.Connecting hole 11 can correspond to plate type heat exchanger close to the edge of panel seat 10
The periphery of access port.
Preferably, connecting hole 11 is spaced apart provided with several along the periphery of panel seat 10.
Water inlet 20, exhaust outlet 30 and pressure gauge 40 are integrated on panel seat 10, and form entirety suppresses module.Enter
The mouth of a river 20 and exhaust outlet 30 are connected inside it through relative two surfaces of panel seat 10 on plate type heat exchanger.
Stop valve 21,31 is separately installed with water inlet 20, exhaust outlet 30, control water inlet 20 and exhaust outlet is respectively used to
30 opening and closing, meets the through-flow and pressurize requirement of cut-off.
Further, this, which suppresses test device, also includes the discharge outlet 50 for plate type heat exchanger draining, and discharge outlet 50 is set
Put on panel seat 10, drainage works are carried out after the completion of plate type heat exchanger water-filling is suppressed.
Stop valve 51 is installed, the opening and closing for controlling the discharge outlet 50 in discharge outlet 50.
Water inlet 20, exhaust outlet 30, discharge outlet 50 and pressure gauge 40 are spaced apart on panel seat 10, are met integration and are set
Also there is certain aesthetic property while meter.
In addition, this, which suppresses test device, may also include the blast pipe being connected on exhaust outlet 30, liquid level gauge etc., pass through liquid level
Filled water amount in meter detection plate type heat exchanger.Blast pipe can select flexible pipe, flexible deformation.
This, which suppresses test device, can also configure water inlet pipe and drainpipe as needed, be connected to water inlet 20 and draining
On mouth 50.
The plate type heat exchanger of the present invention suppresses method of testing, can suppress test device realization using above-mentioned.This is suppressed
Method of testing is used for suppressing after plate type heat exchanger Disintegration overhaul in nuclear power station, to verify the sealing property after maintenance.
With reference to Fig. 1,2, method of testing of suppressing of the invention comprises the following steps：
S1, the blind plate removed on plate type heat exchanger, panel seat 10 is arranged on plate type heat exchanger.
Panel seat 10 replaces blind plate on plate type heat exchanger to be arranged on the original position of blind plate.
In addition, related system is isolated with plate type heat exchanger in the nuclear power station of connecting plate type heat exchanger.
S2, by the water inlet 20 on panel seat 10 into plate type heat exchanger water-filling, while air in plate type heat exchanger leads to
The exhaust outlet 30 crossed on panel seat 10 is discharged.
Wherein, blast pipe and liquid level gauge can be connected on exhaust outlet 30, is judged by liquid level gauge in plate type heat exchanger
Filled water amount.
While step S2 is carried out, the discharge outlet 50 on panel seat 10 is closed.

30。
S4, continue the water-filling into plate type heat exchanger, until plate type heat exchanger internal pressure reaches detection pressure.
The detection pressure is the pressure that plate type heat exchanger is suppressed, the generally operating pressure of correspondence plate type heat exchanger, and compare plate
The operating pressure of formula heat exchanger is slightly larger.
Pressure is reached after detection pressure in plate type heat exchanger, closes water inlet 20, stops water-filling.Observation a period of time, such as
20th, 30 minutes etc..
S5, the sealing property for judging by the change of pressure gauge on panel seat 40 plate type heat exchanger.
When the pressure value detected on pressure gauge 40 keeps constant, then illustrate the good seal performance of plate type heat exchanger, meet
It is required that.When the pressure value detected on pressure gauge 40 declines, then illustrate that plate type heat exchanger has leakage, sealing property is not enough.
In addition, the water leakage situation combination pressure table 40 that can also combine on plate type heat exchanger judges its sealing property.There is leak,
Then pressure value declines.
Further, this to suppress method of testing further comprising the steps of：
S6, by the discharge outlet 50 on panel seat 10 by plate type heat exchanger water discharge.
By above-mentioned steps S1-S5, after completion is suppressed, then step S6 is performed.
Complete after draining, you can pull down panel seat 10 from plate type heat exchanger, blind plate is returned and is attached on plate type heat exchanger.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
