Description

Technical Field

[0001] The utility model belongs to the technical field of valve selection, and specifically relates to a device for valve selection, customization and research and development. Background Art

[0002] As a conveying device for fluids such as water, slurry, and gas, valves play a decisive role in flow control and fluid cutoff. From a structural perspective, there are many types of valves, and the commonly used ones are gate valves, butterfly valves, ball valves, pipe clamp valves, cone valves, etc. When choosing a suitable valve, there is a detailed manual as a reference. The pressure selection of the valve often leaves a certain margin, and the diameter and form selection are usually selected according to the properties of the fluid. However, the slight differences between different fluids often affect the selection and service life of the valve. Therefore, it is necessary to develop a valve selection device to select or customize valves for materials of different properties.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a device for valve selection, customization and research and development. To solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0005] A device for valve selection, customization and development, comprising a pipeline, a plurality of valves, a sensor, and a thermal imager. The valves at least comprise a gate valve, a ball valve, an airbag valve, and a butterfly valve which are sequentially connected in series on the pipeline. The pipeline and the valves are both made of transparent materials.

[0006] The sensors include pressure sensors and flow sensors. There are several pressure sensors connected in series on the pipelines between the valves and on the upstream and downstream pipelines of the start and end valves. There are two flow sensors connected in series between the first upstream pressure sensor and the gate valve, and between the butterfly valve and the last downstream pressure sensor.

[0007] There are at least four thermal imagers, which are respectively aligned with the gate valve, the ball valve, the airbag valve and the butterfly valve for monitoring, and the sensors and thermal imagers are electrically connected to the controller.

[0008] Furthermore, the sensor also includes a temperature sensor and a pH sensor, which are sequentially connected in series at the upstream initial end of the pipeline and are electrically connected to the controller.

[0009] Furthermore, the pipe and the valve are both made of transparent PU material.

[0010] Furthermore, there are six thermal imagers, four of which monitor each valve one by one, and the other two monitor the inlet section of the gate valve and the outlet section of the butterfly valve respectively.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0012] The utility model integrates gate valves, butterfly valves, ball valves, etc., and connects pressure sensors, flow sensors, temperature sensors, PH sensors and other instruments in series for data collection. Thermal imaging is used to monitor the fluid passing through the valve, which can provide basic data for valve selection. In addition, due to the use of transparent materials, it is also convenient to observe the characteristics of the fluid. On this basis, the best valve form can be selected, or local improvement measures for the valve and customized valve production can be proposed.

[0021] like Figure 1 As shown, a device for valve selection, customization and development described in this embodiment includes a pipeline, a plurality of valves, a sensor, and a thermal imager 9. Among them, the pipeline and the valve are made of transparent PU material, which is convenient for observing the flow of fluid. Combined with the accompanying drawings, the valves in this example include a gate valve 1, a ball valve 2, an airbag valve 3, and a butterfly valve 4 connected in series on the pipeline in sequence, and the sensors include five pressure sensors 5, two flow sensors 6, a temperature sensor 7, and a pH sensor 8.

[0022] Three of the pressure sensors 5 are connected in series on the pipelines between the valves, i.e. one is connected in series between the gate valve 1, the ball valve 2, the airbag valve 3, and the butterfly valve 4, and the other two are located upstream of the gate valve 1 and downstream of the butterfly valve 4. Two flow sensors 6 are used to monitor the flow on both sides of the valve, so one flow sensor 6 is connected in series between the first upstream pressure sensor 5 and the gate valve 1, and the other flow sensor 6 is connected in series between the butterfly valve 4 and the last downstream pressure sensor 5, as shown in the attached diagram. The temperature sensor 7 and the pH sensor 8 are connected in series in sequence at the upstream initial end of the pipeline, i.e. the temperature sensor 7 and the pH sensor 8 are located before the first upstream pressure sensor 5, and can monitor the inlet and outlet temperature and pH of the fluid.

[0023] There are six thermal imagers 9, four of which are aligned with each valve for monitoring, and the other two are respectively aligned with the inlet section of the gate valve 1 and the outlet section of the butterfly valve 4. See the attached diagram for a schematic diagram. The thermal imager 9 can be used to perform thermal imaging monitoring on the fluid passing through the valve. The pressure sensor 5, flow sensor 6, temperature sensor 7, pH sensor 8, and thermal imager 9 are all connected to the controller, which is mainly used to collect sensor data.

[0024] During the test, the utility model selects different valves, takes actions such as adjustment and interception on the medium, visually observes the conveying characteristics of the internal fluid, records the easily worn parts of various types of valves, collects the changes of the pressure between various parts of different valves with the flow rate and flow velocity through various sensors, and observes the laminar flow, turbulent flow, particle distribution and other conditions of the fluid passing through different valves through a thermal imaging device. After the above data are collected by the controller, they are processed by a professional valve selection plug-in developed based on software such as CARSAR II, OpenFoam or Fluent. According to the characteristics of the fluid, the best valve form is selected, and local improvement measures for the valve are proposed. Customized production of valves is carried out according to the results of the development software.
