Description

[0001] The present invention relates to a safety valve popping test apparatus for a power plant and a chemical plant,

The present invention relates to a safety flapping test apparatus for a power plant and a chemical plant, and more particularly, to a flapping test apparatus for a safety flap test apparatus for a power plant and a chemical plant, The present invention relates to a flapping test apparatus for safety.

In general, safety valves are installed in pressure vessels and piping of industrial facilities such as power plants, chemical plants, refineries, incinerators, etc., to safeguard devices and facilities even if abnormal pressure occurs in each component.

Such a safety valve is used in various industrial fields such as a power plant operated by high-pressure and low-pressure gas, a high-pressure gas production facility, a petrochemical facility, a boiler and the like. It is stipulated to install mandatory by high pressure gas related regulations in order to prevent explosion or cracking of device or equipment in advance to protect devices and equipment.

On the other hand, a large-scale plant facility includes a large number of valves for controlling and blocking the amount of fluid, and the valves used in the power plant are usually designed to reduce or broaden the cross- A gate valve and a glove valve to prevent backflow of fluid and a check valve to flow only in one direction and a valve that limits the maximum pressure. (Safety Vent) to prevent damage to the equipment or piping by lowering the pressure to below the set pressure. When the pressure of the circuit reaches the set pressure, part or all of the fluid is discharged to keep the pressure in the circuit below the set pressure. And a relief valve (Relief Valve) which is a pressure control valve.

In order to confirm whether or not the safety valve that plays an important role in the operation of the large-scale facility is popping, it is necessary to confirm whether or not the valve is periodically popped. And then tested.

In this case, when the safety test is performed on the safety side, there is a problem that the safety side is separated from the site and the test side is transported to another test site equipped with the test equipment, and then the test is carried again.

As a matter of course, a device capable of directly testing in situ without separating such a safety valve has been proposed in, for example, Japanese Patent Application No. 10-0864273 (Reference 1), Registration No. 10-0898318 (Reference 2) and the like.

The set pressure test apparatus of the safety valve proposed in Reference 1 above is a structure for manually applying a pressure or a load to the hydraulic pump constituting the pressurizing means so that the pressure applied through the hydraulic pump is constantly increased in proportion to the time The waveform of the data output to the display unit of the recorder is not constant and the vibration or the atmospheric pressure of the field can not be reflected.

The safety valve ejection test apparatus proposed in Reference 2 above uses a reciprocating hydraulic cylinder of a piston rod instead of a conventional diaphragm hydraulic jack as an actuator for forcibly opening a safety valve and, immediately after opening the safety valve within a predetermined range, It is impossible to reflect the vibration or the atmospheric pressure in the field even if the vibration exceeds the set value or the set pressure range is not suitable for the test in the workplace where the safety valve is installed as in Reference 1, There is a problem of low reliability.

In the case of References 1 and 2 above, when sudden vibration and atmospheric pressure rise or fall occur in a workplace equipped with a safety valve or a safety valve, there is a high risk of distortion of the waveform of the graph on the pressure.

Furthermore, even though the test apparatuses proposed in the above References 1 and 2 obtain information on the operating pressure of the equipments installed in the test in advance, the actual applied pressure changes in real time, And there is a problem that the reliability of the safety test is lowered. In addition, if the inspector does not stop the operation of the hydraulic pump even after the operation rod has been operated, the hydraulic pump is continuously driven. Therefore, the safety valve, the load cell or the hydraulic pump is also likely to be broken when the pressure is applied.

Accordingly, in order to solve the problems of the conventional art as described above, a popping test is carried out on-line for a safety valve installed and operated in a facility or an apparatus of a power plant or a chemical plant, , And to provide a safety flapping test device for power plants and chemical plants that can stop the test when vibration and atmospheric pressure changes, which can affect the flapping test, to provide reliability in the flapping test.

In addition, the present invention tests whether or not the safety valve is set at a predetermined pressure without separating the safety valve from a facility or an apparatus of a power plant or a chemical plant, and controls the hydraulic pump so as to linearly induce the applied pressure. And a safety flapping test apparatus for a power plant and a chemical plant for stopping the driving of the hydraulic pump.

In order to solve such a technical problem,

When a load signal of the load cell is input, To calculate a measured pressure and display it as a graph; And the data processing means displays vibration and atmospheric pressure information of the vibration sensor and the atmospheric pressure sensor.

The data processing means stores the measured pressure in a memory at a preset time interval, compares the measured pressures in order, and when a maximum value is found, it determines that the measured pressure is a fapping pressure, and the fapping pressure is output together with the graph .

The data processing means sequentially compares the measured pressures stored in the memory, selects a large value as the temporary pumping pressure, finalizes the final temporary pumping pressure as the pumping pressure, and displays the numerical value together with the graph.

The data processing means controls the hydraulic pump by setting a value obtained by subtracting the operation pressure from a set pressure at which the safety valve is popped, when the operation pressure of the facility or the apparatus equipped with the safety valve is inputted.

The safety flapping test apparatus according to the present invention can control the discharge pressure of the hydraulic pump linearly while performing the flapping test without separating the safety valve installed at the power plant and the chemical plant from the facility or the apparatus in the field, Or when the atmospheric pressure is out of the set range, the driving is stopped to prevent the flapping test in an unstable environment, thereby improving the reliability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. It is to be understood, however, that the invention is not intended to be limited to the particular forms disclosed, but on the contrary, is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

1 and 2, the safety flap testing device for a safety valve for a power plant and a chemical factory according to the present invention is provided with a safety valve 1 for preventing the safety valve 1 from being detached from a facility or an apparatus of a power plant and a chemical plant. When the vibration within the work area exceeds the set value or when the atmospheric pressure is out of the set range when testing whether popping occurs at the set pressure, the driving of the hydraulic pump 10 is stopped to prevent the flapping test in an unstable environment, The application pressure of the hydraulic pump 10 for inducing the set pressure is linearly increased in proportion to the time and the safety valve 1 is tested. When the flapping is sensed, the operation of the hydraulic pump 10 is stopped, It is possible to prevent the failure of the safety valve 1, the load cell or the hydraulic pump 10 due to the failure.

The safety flapping test apparatus for a power plant and a chemical plant according to the present invention is for testing whether a safety valve 1 installed in a facility such as a pressure vessel or a piping or a piping of a power plant and a chemical plant is popped at a set pressure, A hydraulic pump (10) having a control valve (10a) for transmitting hydraulic pressure to a hydraulic jack (12) for raising an operating rod (2) of a safety valve (1) installed in a workshop of a chemical plant and controlling the flow rate; A pressure sensor (20) for measuring the discharge pressure of the hydraulic pump (10); A load cell 30 for converting a load applied between the operating rod 2 and the hydraulic jack 12 of the safety valve 1 into an electrical load signal; A vibration sensor (37) for detecting vibration in the work space; An atmospheric pressure sensor 39 for measuring the atmospheric pressure inside the workplace; The control unit controls the hydraulic pump 10 such that the discharge pressure sensed by the pressure sensor 20 linearly reaches a predetermined applied pressure, and when a load signal is input from the load cell 30, And data processing means (40) for stopping the operation of the hydraulic pump (10) when the vibration of the vibration sensor (37) exceeds the set value or the atmospheric pressure is out of the setting range.

At this time, the safety flapping test apparatus according to the present invention can be applied to a power plant or selectively applied to a chemical plant, and even if it is not separately described in the claims, it can be applied to various industries such as a power plant, a chemical plant, It is to be understood that the present invention is also applicable to a facility.

Hereinafter, the constitution of each part of the present invention will be described in detail.

First, the safety valve 1 is installed in a facility or an apparatus of a power plant and a chemical plant. In order to test the safety valve 1, a valve cap (not shown) is disassembled and then an operation The adapter 3 is mounted on the rod 2 and the jig 4 provided with the hydraulic jack 12 is installed on the safety valve 1 and the load cell 30 is mounted on the hydraulic jack 12 and the adapter 3.

The hydraulic pump 10 for supplying the hydraulic pressure to the hydraulic jack 12 can control the discharge pressure of the hydraulic pump 10, that is, the hydraulic pressure transmitted to the hydraulic jack 12, in accordance with the control signal of the data processing means 40 .

To this end, the hydraulic pump 10 is provided with a control valve 10a to control the flow rate in accordance with the control signal of the data processing means 40. [

The pressure sensor 20 is installed on the hydraulic line 11 connecting the hydraulic pump 10 and the hydraulic jack 12 to measure the discharge pressure of the hydraulic pump 10 and the pressure sensor 20 ) Is input to the data processing device 40. The data processing device 40 is connected to the data processing device 40,

The load cell 30 converts a load applied between the actuating rod 2 and the hydraulic jack 12 of the safety valve 1 into an electrical load signal and the load signal is input to the data processing means 40.

At this time, the control signal of the hydraulic pump 10 output from the data processing means 40 is converted into an analog signal through the interface means 50 as a digital signal to control the hydraulic pump 10 The discharge pressure sensed by the pressure sensor 20 and the electrical load signal of the load cell 30 are converted into a digital signal through the interface means 50 as an analog signal and input to the data processing means 40 do.

Therefore, the interface means 50 includes an A / D converter for converting an analog signal into a digital signal and a D / A converter for converting a digital signal into an analog signal, and also performs a function of signal distribution.

The interface means 50 is connected to the data processing means 40. The data processing means 40 may be a laptop computer or a tablet PC which can be carried on the field as well as a normal industrial computer. In particular, when the interface means 40 is a notebook or a tablet PC, the data processing means 40 can be connected by a USB cable and can be easily connected by a plug and play (P & P) method.

A limit switch which is an operating rod sensing means 35 is installed on the jig 4 provided with the hydraulic jack 12 so as to detect when the operating rod 2 rises above a predetermined height, So that a signal is generated. Of course, the limit switch may be provided separately on the upper side of the safety valve 1 located on the lower side of the load cell 30, or may be provided with a limit switch as the working rod sensing means 35 on one side of the working rod 2 Do.

Therefore, when the operating rod 2 rises above the set height, the operating rod sensing means 35 directly senses it, and it can be determined as the time of the papping. This means that if the operation sensing signal is inputted from the working load sensing means 35 in the data processing means 40, it is judged that the flapping has occurred and the driving of the hydraulic pump 10 is stopped.

On the other hand, the vibration and atmospheric pressure inside the workplace where the safety valve (1) of the power plant and the chemical plant are installed may affect the pumping test, so if the vibration in the workplace exceeds the set value or the atmospheric pressure is out of the set range, Measurement is also very important.

Accordingly, the present invention further includes a vibration sensor 37 for detecting vibration in the workplace and an atmospheric pressure sensor 39 for measuring the atmospheric pressure inside the workplace. This makes it possible to test more reliably by monitoring the test environment in which the test is performed (1).

In this case, the vibration sensor 37 and the atmospheric pressure sensor 39 are converted into digital data through the interface means 50 in the case of the analog system and input to the data processing means 40, ). ≪ / RTI >

The vibration and atmospheric pressure information of the surroundings equipped with such a safety valve is displayed together with the pressure graph.

At this time, the vibration sensor 37 may be attached to the safety valve 1 to measure the vibration applied to the safety valve 1. The atmospheric pressure sensor 39 may be installed separately from the safety valve 1 to measure the atmospheric pressure It is possible to reduce the time difference, and if necessary, it can be attached to a notebook computer such as the data processing means 40.

The data processing means 40 controls the hydraulic pump 10 so that the discharge pressure sensed by the pressure sensor 20 linearly reaches the set applied pressure, The operation of the hydraulic pump 10 is stopped when the detected vibration exceeds the set value or the atmospheric pressure is out of the set range. To this end, the memory 42 of the data processing means 40 stores information about the vibration set value and the atmospheric pressure setting range.

In this case, the vibration setting value may be 60 dB (V), which is an evaluation vibration level according to a factory noise and vibration emission allowance standard. Therefore, when the vibration processing value is 60 dB (V) or less, , And when it exceeds 60 dB (V), it is determined that the abnormal situation is present and the driving of the hydraulic pump 10 is stopped.

If the data processing means 40 determines that the pressure is within the range of 0.8 to 1.2 atmospheres, the data processing means 40 determines that the pressure is outside of the range of 0.8 to 1.2 atmospheres. If the pressure is less than 0.8 atmospheres or exceeds 1.2 atmospheres And stops the driving of the hydraulic pump 10. [

Hereinafter, the operation of the safety flapping test apparatus for a power plant and a chemical plant according to the present invention will be described with reference to FIGS. 1 to 3. FIG.

According to the above configuration, the inspector inputs the set pressure of the facility or equipment in which the safety valve 1 is installed and safety-side information such as the installation position, model name, and cross-sectional area of the safety valve 1 by using the notebook computer as the data processing means 40 , The control signal is applied to drive the hydraulic pump 10.

In this case, when the discharge pressure of the hydraulic pump 10 sensed through the pressure sensor 20 is input, the data processing means 40 controls the hydraulic pump 10 to linearly reach a predetermined applied pressure .

At this time, for example, when the set applied pressure is 100 kg / cm 2, the discharge pressure of 10 kg / cm 2 can be controlled to be outputted so that the operation pressure can be set to reach the set pressure set at 10 seconds. In this way, by operating the discharge pressure to linearly increase in proportion with time, it is possible to test a plurality of safety valves (1) under the same conditions. It goes without saying that the setting of the applied pressure and the adjustment of the discharge pressure can be set and adjusted under various conditions.

The hydraulic pressure is applied to the hydraulic jack 12 so that the load is applied in the direction in which the operation rod 2 of the safety valve 1 is to be elevated. The load cell 30 is connected to the operation rod 2 of the safety valve 1, And outputs the converted electric load signal to the data processing means 40. The data processing means 40 receives the electric load signal and outputs the electric load signal.

When the load signal of the load cell 30 is input, the data processing unit 40 divides the load signal by the area of the corresponding safety valve 1 to calculate the measured pressure and displays the measured pressure on a graph.

At this time, the graph of the measured pressure is stored in the memory 42 of the data processing means 40, which can be used as test data by extracting the puffing test data of a certain safety level through data back-up. In this case, it can be judged as normal when the measurement pressure is within the tolerance range (for example, ± 5% range of the set pressure) based on the set pressure, which is the pressure that the safety valve (1) In this case, the measured pressure is lowered after obtaining the peak value immediately before the pumping.

On the other hand, there is a large error in confirming the graph with the naked eye and securing the numerical value of the popping pressure. The data processing means 40 stores the measured pressure in the memory 42 at a set time interval (for example, 1/1000 second), compares the measured pressures in order, and when the maximum value is found, And outputs it along with the graph. That is, for example, assuming that measured pressures P1 to P5 are measured in units of 1/1000 second, if P1 and P2 are compared, if P2 is larger, P2 is judged to be a temporary popping pressure and P2 and P3 are compared. If it is larger, P3 is judged as a temporary popping pressure. Thereafter, P3 and P4 are compared in the same manner, and if P3 is larger, P3 is still judged as a temporary pumping pressure and compared with P5. That is, the plurality of measured pressures are sequentially compared to calculate the temporary flapping pressure, and finally the remaining temporary flapping pressure is determined as the flapping pressure. By displaying the above-described flapping pressure numerically and displaying it together with the graph, objectivity and accuracy can be secured as compared with the naked eye checking of the flapping pressure.

The operating pressure may be input to the data processing means 40 beforehand so as to reflect the operation pressure of the facility or the apparatus provided with the safety valve 1, It is possible to control the hydraulic pump 10 by setting a value obtained by subtracting the operating pressure of the equipment or the apparatus provided with the safety valve 1 from the set pressure at which the valve 1 is popped. This makes it possible to set the applied pressure automatically according to the situation of the site, and to perform more accurate pumping test. For example, if the set pressure is 200 kg / cm 2 and the operating pressure of the equipment or apparatus equipped with the safety valve 1 is 90 kg / cm 2, the applied pressure is 110 kg / cm 2, Cm < 2 >.

On the other hand, the data processing means 40 analyzes the extracted test data to calculate the tapping pressure. At this time, when the load signal of the load cell 30 is inputted, the data processing unit 40 divides the load signal by the area of the corresponding safety valve 1 to calculate the measured pressure and displays the measured pressure on a graph.

If the vibration sensed by the vibration sensor 37 monitoring the surrounding environment 1 is less than or equal to the set value of 60 dB (V), it is determined as normal. If the vibration exceeds 60 dB (V) If the atmospheric pressure sensed by the atmospheric pressure sensor 39 is within the range of 0.8 to 1.2 atmospheres, it is determined to be normal. If the atmospheric pressure is out of the range, it is less than 0.8 atmospheres or exceeds 1.2 atmospheres. The driving of the hydraulic pump 10 is stopped, and such vibration and atmospheric pressure information is also displayed together with the graph.

The measured pressure calculated through the data processing means 40 is output as a graph of time as shown in FIG. As shown in FIG. 3, the pressures measured in the set time intervals are sequentially compared, and when the maximum value is found, the pressure is determined as the papping pressure (P). During such pressure measurement, for example, the pressure graph is stopped from time point B when the vibration or atmospheric pressure information measured by the vibration sensor 37 or the atmospheric pressure sensor 39 exceeds the vibration set value or out of the atmospheric pressure setting range.

Of course, after a set time of, for example, 2 to 3 seconds after this point, a message window requesting remeasure is popped up to correspond.
