Background technology
Existing valve detection method is by pressure test, i.e. the mainly casing rigidity test of valve and sealing examination
Test.For a long time, pressure test method both domestic and external is all carried out at normal temperatures, very big with the temperature difference under actual condition, because
This cannot accurately record the quality condition under valve actual condition, and valve is under the working environment of High Temperature High Pressure, and its material is very
It is susceptible to creep, after the valve leading to some qualified in cold test applies to actual working environment, the feelings such as leakage occur
Condition.
Content of the invention
For the shortcoming overcoming existing valve pressure test can only carry out at normal temperatures, the present invention provides one kind can simulate
The valve Hot Test of operating mode.
The technical solution adopted for the present invention to solve the technical problems is a kind of valve Hot Test, including tested
Valve, water pump, vacuum tank, pressure regulator valve, pressure transducer A, pressure transducer B, stop valve A, stop valve B and water tank, water pump with steady
Pressure tank connect, be connected with pressure regulator valve, stop valve A, pressure transducer A and tested valve after vacuum tank in turn, after tested valve according to
Secondary be connected to pressure transducer B, stop valve B, water tank, water tank is connected with water pump, is all connected by pipeline, voltage stabilizing between above-mentioned each part
Equipped with pressure gauge and relief valve on tank, thermometer A is installed between pressure transducer A and stop valve A, pressure transducer B with cut
Thermometer B is installed between disconnected valve B, on the pipeline between thermometer A and stop valve A install electric heater A, thermometer B with cut
Electric heater B is installed on the pipeline between disconnected valve B.
Thermometer A and thermometer B is thermocouple temperature measurement instrument.
Electric heater A and electric heater B is tube electric heater.
The invention has the beneficial effects as follows：
1st, actual condition can be simulated, such that it is able to accurately record quality condition under actual condition for the valve；
2nd, this test device is Open architecture, goes for polymorphic type, the valve of many specifications；
3rd, temperature is automatically controlled by thermocouple temperature measurement instrument, temperature stabilization and easy to adjust.

Specific embodiment
As shown in figure 1, a kind of valve Hot Test, including tested valve 9, water pump 1, vacuum tank 15, pressure regulator valve 4,
Pressure transducer A8, pressure transducer B10, stop valve A5, stop valve B13 and water tank 14, water pump 1 is connected with vacuum tank 15, surely
It is connected with pressure regulator valve 4, stop valve A5, pressure transducer A8 and tested valve 9 in turn after pressure tank 15, connect successively after tested valve 9
There are pressure transducer B10, stop valve B13, water tank 14, water tank 14 is connected with water pump 1, between above-mentioned each part all by pipeline even
Connect, equipped with pressure gauge 2 and relief valve 3 on vacuum tank 15, thermometer A7 is installed between pressure transducer A8 and stop valve A5, pressure
Thermometer B11 is installed between force transducer B10 and stop valve B13, the pipeline between thermometer A7 and stop valve A5 is installed
Electric heater A6, the pipeline between thermometer B11 and stop valve B13 is installed electric heater B12, thermometer A7 and thermometer
B11 can from thermocouple temperature measurement instrument and other can measurement temperature instrument, electric heater A6 and electric heater B12 can select
With tube electric heater and other can heat the heater of pipeline.
Original state, tested valve 9 is accessed in pipeline, the Shell test pressure of adjustment pressure regulator valve 4 outlet pressure to regulation
Power, stop valve A5 is closed, and stop valve B13 is in opening, and electric heater A6 and electric heater B12 connects electricity
Source.
Casing rigidity is tested：Open stop valve A5, make whole pipeline close stop valve B13 after being full of medium, system is boosted,
Electric heater A6 and electric heater B12 begins to warm up simultaneously, when pressure reaches setting, closes stop valve A5, temperature is by temperature
Degree meter A7 and thermometer B11 controls, and selects thermocouple temperature measurement instrument, therefore thermocouple signals are controlled automatically at certain model in the present embodiment
In enclosing, after pressurize terminates, check whether housing has leakage or the phenomenon of visible deformation.
Leakage test：After casing rigidity test inspection is without exception, leakage test can be carried out, close tested valve 9, unlatching is cut
Disconnected valve B13, observes pressure transducer A8 and pressure transducer B10, and within the dwell time, pressure value keeps constant as qualified.
