Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve testing, in particular to an automatic pressure-pressing device for valves of various models. Background Art
[0002] In industrial construction projects, valve pressure testing is a crucial link, and its quality is directly related to the safety and reliability of the entire project. National and industry specifications have strict standards for this. Especially in large-scale industrial projects, due to the large number of valves involved in various models, how to efficiently and quickly complete the valve pressure testing work, ensure that the valve quality meets the actual needs of the project, and thus avoid possible leakage and quality problems in the future, has become a key challenge in the project execution process.
[0003] At present, the valve pressure testing system generally adopts the traditional single valve pressure testing device, which can only test a single type of valve at a time. According to industry regulations, the pressure test needs to be maintained for a certain period of time after each pressure test, which makes the entire pressure testing process time-consuming. For the testing needs of large quantities of valves, the traditional pressure testing method will undoubtedly consume a lot of time.
[0004] To meet this challenge, some valve manufacturers have turned to automated pressure testing devices. The design idea of this type of device stems from the fact that production lines usually focus on producing a certain type of valve in a specific period of time. Therefore, these automatic pressure testing devices are mainly used to perform efficient pressure testing on a single type of valve to meet the needs of fast and continuous production on the production line. Different types of pressure testing devices are required for different types of valves, which is costly to use. Summary of the invention
[0005] In order to solve the above problems, the utility model provides a multi-model valve automatic pressure testing device, which can adapt to different types of valves for pressure testing and reduce costs.
[0006] The technical solution is as follows: an automatic pressure-pressing device for multiple types of valves, comprising a cylinder, characterized in that valve mounting ports of different sizes are arranged on the outer wall of the cylinder, a corresponding water collector is arranged in the cylinder, a blind plate is installed on the valve mounting port, one end of the cylinder is connected to one end of a pressure-pressing pump through a water inlet pipe, and the other end of the pressure-pressing pump is a water source inlet, a pressure sensor is installed at the other end of the cylinder, the pressure sensor is connected to the control system through a signal line, a drain pipe is arranged at the bottom of the cylinder, the control system comprises a frequency converter and a programmable controller, the pressure sensor and the frequency converter are both connected to the programmable controller, the frequency converter and the programmable controller are both connected to a three-phase power supply, and the pressure pump is connected to the frequency converter.
[0007] Further, the programmable controller is provided with an RJ45 interface and is connected to the control panel through a network cable.
[0008] After adopting the present utility model, valves to be pressure-tested are installed according to test requirements and docked to the valve installation ports. For models that are not needed, blind plates are used for plugging, and external water sources and power supplies are connected. Since a programmable controller is designed, the operation of the pressure pump can be controlled by using a preset test pressure value, and pressure holding tests can be performed according to the set time, achieving the pressure testing of different models of valves with one device and reducing costs. Description of the Drawings
[0009] Figure 1 is a schematic structural diagram of the present utility model;
[0010] Figure 2 is an electrical control schematic diagram of the present utility model. Detailed Embodiment
[0011] See Figure 1 , Figure 2 As shown, a multi-model valve automatic pressure testing device includes a cylinder body 1. Different-sized valve installation ports 2 are provided on the outer wall of the cylinder body 1. A blind plate 3 is installed on the valve installation port 2. The flange connection method is adopted, and the blind plate 3 can be disassembled. When a valve of the corresponding size needs to be tested, the corresponding blind plate 3 is removed and the valve is installed. The remaining blind plates 3 continue to achieve plugging. One end of the cylinder body 1 is connected to one end of a pressure pump 5 through a water inlet pipe 4. The other end of the pressure pump 5 is a water source inlet. Each, the other end of the cylinder body 1 is provided with a pressure sensor 6. The pressure sensor 6 is connected to a control system 7 through a signal line. A drain pipe 8 is provided at the bottom of the cylinder body.
[0012] In this embodiment, since four valve installation ports 2 are provided at the front, top, and back respectively, within the limited volume, it can simultaneously pressure-test 12 valves. This innovation mainly benefits from the installation of a water collector in the cylinder body 1, which can divide a water source entering the cylinder body into 12 paths and connect them to 12 valve installation ports respectively.
[0013] The control system includes an inverter 9 and a programmable controller 10. The pressure sensor 6 and the inverter 9 are both connected to the programmable controller 10. The inverter 9 and the programmable controller 10 are both connected to a three-phase power supply. The pressure pump 5 is connected to the inverter 9. The programmable controller 10 is provided with an RJ45 interface and is connected to the control panel 11 through a network cable.
[0014] Set the required test pressure value on the control panel 11 and press the start button to start working. Once the pressure in the pressure cylinder 1 reaches the preset value, the pressure pump 5 will stop running. At this time, maintain the pressure according to the set requirements and conduct a pressure holding test within the specified time. If the test is qualified, the device will automatically enter the next working cycle.
[0015] In practical applications, only one operator is required to complete the pressure test of the entire batch of valves, which greatly saves human resources and improves the accuracy and efficiency of the test.
