Description

Technical Field

[0001] This invention relates to the field of simulated factory technology, specifically to a wirelessly controlled simulated valve and its usage method. Background Technology

[0002] A simulated factory refers to a device used for operator training. It simulates chemical plant operations through simulated instruments, valves, factory models, operator skills training systems, and chemical simulation software. A type of simulated factory training device with a physical model is widely used in chemical vocational schools across China. The valves and pipelines are fixedly connected and then connected to the operator skills training system through a series of sensors such as valve position detectors. When trainees turn the valves, the operator skills training system receives the valve opening signal through a signal transmission module.

[0003] The simulated factory site has up to a hundred valves. Due to cost constraints, only the main valve positions are usually equipped with data transmission functions, numbering around a few dozen. However, the initial values ​​of each simulated valve cannot be set and recorded, and the demand for these valves is very high during the training process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a wirelessly controlled simulated valve and its usage method. A chip is mounted on the valve body, storing the corresponding valve body's tag number information. This tag number information can be read by a card reader located in the internal cavity of the valve cover and transmitted wirelessly to an operator skills training system. A sensor for detecting the valve stem rotation is also installed in the internal cavity of the valve cover. Similarly, the valve stem rotation can be transmitted wirelessly to the operator skills training system, enabling the system to record the tag number information and rotation amount of each valve.

[0005] The first aspect of this invention provides a wirelessly controlled simulated valve, comprising:

[0006] Valve body;

[0007] A valve seat, which is detachably mounted on the valve body;

[0008] A valve cover is mounted on the upper surface of the valve seat. The inside of the valve cover is a cavity, and a through hole communicating with the cavity is opened on the upper end face of the valve cover.

[0009] A valve stem, one end of which passes through the through hole and is rotatably mounted in the cavity;

[0010] A sensor, located within the cavity, is used to detect the amount of rotation of the valve stem;

[0011] A chip is disposed on the valve body, and the chip stores the reference number information of the valve body;

[0012] A card reader, located within the cavity, is used to read the tag information stored within the chip;

[0013] A wireless transmission module is located inside the cavity. The wireless transmission module is used to transmit the rotation information of the valve stem and the tag number information to the operator skills training system.

[0014] In one embodiment, the other end of the valve stem is located above the valve cover, and a handwheel is mounted on the other end of the valve stem.

[0015] In one embodiment, a limiting groove adapted to the shape and size of the outer wall of the valve seat is formed on the top of the valve body, and the valve seat is engaged in the limiting groove.

[0016] In one embodiment, the limiting groove is hexagonal.

[0017] In one embodiment, the chip is mounted in the limiting groove.

[0018] In one embodiment, a battery is provided inside the valve cover, which provides power to the sensor, the wireless transmission module, and the card reader.

[0019] In one embodiment, a circuit board is also provided inside the valve cover, and the battery, the sensor, the card reader and the wireless transmission module are all mounted on the circuit board.

[0020] In one embodiment, an opening communicating with the cavity is formed on the side wall of the valve cover. The simulated valve also includes a mounting component, which includes a horizontal base plate and a vertical side plate connected to one side of the horizontal base plate. The circuit board is mounted on the horizontal base plate, the horizontal base plate is inserted into the cavity, and the vertical side plate covers the opening.

[0021] In one embodiment, a handle is provided on the side of the vertical side plate opposite to the valve cover.

[0022] A second aspect of the present invention provides a method for using a wirelessly controlled simulated valve, applicable to the aforementioned wirelessly controlled simulated valve, the method comprising:

[0023] Step 1: Install the valve cover onto the valve body, and the card reader reads the tag information stored in the chip;

[0024] Step 2: Rotate the valve stem, and the sensor detects the amount of rotation of the valve stem;

[0025] Step 3: The rotation information of the valve stem detected by the sensor and the tag number information read by the card reader are transmitted to the operator skills training system through the wireless transmission module.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The wirelessly controlled simulated valve provided by this invention includes a valve body, a valve seat, a valve cover, and a valve stem. A chip is provided on the valve body, and the chip stores the corresponding valve position information, i.e., the valve position number at the corresponding position on the process flow diagram. The position information can be read by a card reader set in the cavity inside the valve cover and transmitted to the operator skills training system by a wireless transmission module. A sensor for detecting the rotation amount of the valve stem is also set in the cavity inside the valve cover. Similarly, the rotation amount of the valve stem can also be transmitted to the operator skills training system through the wireless transmission module, so that the system can record the position information of each simulated valve and their rotation amount.

[0028] 2. In the method of using the wirelessly controlled simulated valve provided by the present invention, the valve body with chip is fixed on the simulated pipeline. The operator only needs to hold the valve cover with sensor, card reader and wireless transmission module installed in hand, find the corresponding valve body, and insert the valve seat under the valve cover into the limiting groove on the top of the valve body to complete the connection between the simulated valve and the operator skills training system. The whole process is smooth and uninterrupted, which improves the efficiency of simulation training.

[0029] 3. In the wirelessly controlled simulation valve provided by this invention, only a few valve bodies need to be installed in the simulation factory. The operator only needs to hold the valve cover to complete the entire simulation training process, saving the cost of installing valves. In the past, there were many fixed valves. If a fault occurred, it was necessary to send people to the site for repair, which affected the customer's user experience. However, if the simulation valve of this invention is damaged, it can be immediately replaced with a spare valve without any installation and debugging operations, which can ensure that the customer can use it at any time.

[0030] 4. In the past, the opening value of fixed valves could not be set, and each valve could only be opened manually on site. Before the shutdown operation or emergency operation, the valve had to be started successfully. However, the initial opening of the wireless control simulation valve provided by this invention is set by the operator's skill training system, which is not limited by the site. The shutdown or emergency operation can be performed after the steady state of successful startup is loaded directly in the software. Attached Figure Description

[0035] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0036] Example

[0037] Reference Figure 1 and Figure 2 As shown, this embodiment provides a wirelessly controlled simulated valve comprising: a valve body 2, a valve seat 1, a valve cover 4, a valve stem, and a chip 3. The top of the valve body 2 has a limiting groove that matches the shape and dimensions of the outer wall of the valve seat 1. The valve seat 1 is detachably connected to the valve body 2 by being engaged within the limiting groove. This limiting groove is hexagonal, which not only limits and fixes the valve seat 1 but also limits the valve cover 4, preventing it from rotating along with the valve stem. The valve cover 4 is mounted on the upper surface of the valve seat 1, and the interior of the valve cover 4 is a hollow cavity. A through hole communicating with the cavity is opened on the upper end face of the valve cover 4. One end of the valve stem passes through the through hole and is rotatably installed in the cavity, while the other end of the valve stem is located above the valve cover 4. The chip 3 is set in the limiting groove, and the chip 3 stores the tag number information of the valve body 2. The cavity of the valve cover 4 is equipped with a sensor 7, a card reader 6, and a wireless transmission module. The sensor 7 is used to detect the rotation amount of the valve stem, the card reader 6 is used to read the tag number information stored in the chip 3, and the wireless transmission module is used to transmit the rotation amount of the valve stem and the tag number information to the operator skills training system. Through the coordinated action of the sensor 7, the card reader 6, and the wireless transmission module, the tag number information of the valve body 2 and the rotation amount information of the valve stem in each simulated valve can be transmitted and stored in the operator skills training system. This facilitates the knowledge and recording of the opening degree of the simulated valve, which is convenient for subsequent database retrieval and consultation. In turn, it allows each operator to understand the opening degree data of each simulated valve in a timely manner during the training process, thereby improving the training efficiency.

[0038] In this embodiment, the wireless transmission module is selected as the wireless network card 8. Other modules that can transmit the rotation amount information and tag number information of the valve stem to the system can replace the wireless network card 8, such as ZigBee module, LoRa module, NB-IoT module, etc., and are all within the protection scope of this invention.

[0039] In this embodiment, sensor 7 is an optical sensor. Other sensors 7 that can detect the amount of valve stem rotation can replace the optical sensor, such as magnetic sensors, torsion sensors, etc., and are all within the protection scope of this invention.

[0040] Reference Figure 1 As shown, the other end of the valve stem is located outside the valve cover 4. The other end of the valve stem is detachably mounted with a handwheel 9 via a valve stem nut. The valve stem is rotatably connected to the inner wall of the through hole on the valve cover 4 that communicates with the cavity. The operator rotates the handwheel 9 to drive the valve stem to rotate, and the amount of rotation is detected by the sensor 7.

[0041] In the simulated valve provided in this embodiment, the valve cover 4 is also equipped with a battery 5 and a circuit board. The battery 5 provides the power required for the normal operation of the sensor 7, the wireless network card 8 and the card reader 6. All components in the valve cover 4, namely the sensor 7, the card reader 6, the wireless network card 8 and the battery 5, are mounted on the circuit board. The circuit board can supply the power of the battery 5 to each component. At the same time, the tag information and the rotation amount information of the valve stem can also be transmitted to the wireless network card 8 through the circuit board.

[0042] Reference Figure 1 and Figure 2 As shown, the simulated valve provided in this embodiment also includes an installation component, which includes a horizontal base plate and a vertical side plate connected to one side of the horizontal base plate. An opening communicating with a cavity is provided on the side wall of the valve cover 4. The horizontal base plate is inserted into the cavity through the opening. The circuit board is installed on the horizontal base plate. The vertical side plate covers the opening. A handle is provided on the side of the vertical side plate away from the valve cover 4. By pushing and pulling the handle, the horizontal base plate can be easily removed from the cavity of the valve cover 4, which facilitates maintenance personnel to perform routine maintenance on the circuit board on the horizontal base plate and further ensures that the entire simulated valve can be repaired in a timely manner when damaged.

[0043] This embodiment also provides a method for using a wirelessly controlled simulated valve, specifically including the following steps:

[0044] Step 1: Install the valve cover 4 onto the valve body 2 via the valve seat 1, and the card reader 6 will then read the tag number information stored in the chip 3.

[0045] Step 2: Rotate handwheel 9, which is to rotate the valve stem. Sensor 7 detects the amount of rotation of the valve stem.

[0046] Step 3: The rotation information of the valve stem detected by sensor 7 and the tag number information read by card reader 6 are transmitted to the operator skills training system through wireless network card 8.

[0047] In the above-mentioned wireless control simulation valve usage method, the operator only needs to hold the valve cover 4 to complete the entire simulation training process, which can reduce the number of traditional valves to be installed. Only the valve body 2 with limit groove needs to be installed at the key nodes, saving the cost of valve installation.

[0048] Specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention.
