[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0036] Embodiment 1:

[0037] The utility model provides an automatic control device for a test manifold 3, which is used to solve the technical problem of inconvenient control of the test manifold 3. The automatic control device for the test manifold 3 comprises a box 1, a test manifold 3 and a controller 8, wherein:

[0038] The top of the box body 1 is open, and other components in the box body 1 are installed inside the box body 1 through the opening. A box cover 2 is connected to the opening, and the box cover 2 covers the opening. Opening and closing the box cover 2 facilitates the inspection of other components in the box body 1. More preferably, a locking structure is provided on the box cover 2 to prevent human damage to the components in the box body 1.

[0039] The test manifold 3 includes a four-way pipe 31, a liquid inlet pipe 32, and three liquid outlet pipes 33. A circular hole is provided on each of the four side walls of the box 1. The circular hole is used to pass the liquid inlet pipe 32 and the liquid outlet pipe 33, and the diameter of the circular hole is adapted to the diameter of the liquid inlet pipe 32 and the liquid outlet pipe 33. The four-way pipe 31 is installed in the box 1. The four-way pipe 31 is provided with four interfaces for connecting pipes. One end of the liquid inlet pipe 32 and the three liquid outlet pipes 33 is respectively connected to the four interfaces of the four-way pipe 31, and the other ends of the liquid inlet pipe 32 and the three liquid outlet pipes 33 are respectively connected to the four interfaces of the four-way pipe 31. The four circular holes extend out of the box body 1. The ends of the liquid inlet pipe 32 and the liquid outlet pipe 33 extending out of the box body 1 are each provided with a flange interface 34. The flange interface 34 facilitates the connection of other pipes with the liquid inlet pipe 32 and the liquid outlet pipe 33. The liquid inlet pipe 32 and the three liquid outlet pipes 33 are each provided with a flow meter 5, a pressure sensor 6 and a solenoid valve 7. The flow meter 5 is used to detect the flow rate of the liquid in the pipeline, the pressure sensor 6 is used to detect the pressure of the liquid in the pipeline in real time, and the solenoid valve 7 is used to control the on-off of the pipeline and adjust the flow in the pipeline.

[0040] The controller 8 is installed on the box cover 2, and the controller 8 is located inside the box body 1. In this way, the internal environment of the box body 1 is relatively stable, which is beneficial to extending the service life of the controller 8. At the same time, when the inside of the box body 1 is inspected, the controller 8 is opened with the box cover 2, avoiding the controller 8 affecting the operation of the inspector. The above-mentioned flow meter 5, the above-mentioned pressure sensor 6 and the above-mentioned solenoid valve 7 are all electrically connected to the controller 8. The data detected by the flow meter 5 and the pressure sensor 6 are transmitted to the controller 8. After analysis by the controller 8, the solenoid valve 7 is adjusted to adjust the internal pressure of each pipeline. Specifically, the controller 8 is a PLC.

[0041] Through the above structure, when the test manifold 3 automatic control device provided by the utility model is used, the pipe for discharging liquid is connected to the flange interface 34 on the oil inlet pipe, and the pipe for discharging liquid is connected to the flange interface 34 on the oil outlet pipe. The flow meter 5 and the pressure sensor 6 collect the flow and pressure data in the pipeline, and accurately adjust the opening and closing of the solenoid valve 7 through the controller 8, so as to smoothly adjust the pressure in each oil outlet pipe, and the adjustment is convenient. The real-time adjustment using the controller 8 makes the adjustment more sensitive and reliable, reduces the occurrence of drilling accidents, and is safer to use. Therefore, when the test manifold 3 automatic control device provided by the utility model is used, it only needs to connect the oil pipe to the oil inlet pipe and the oil outlet pipe through the flange interface 34 according to the use requirements, which is more convenient to use, and the pressure of each pipeline can be adjusted in real time by the controller 8, which is safer to use.

[0042] An optional implementation of this embodiment is as follows: a filter assembly 9 is also provided on the liquid inlet pipe 32, and the filter assembly 9 is used to filter the liquid in the pipeline to prevent impurities in the liquid from accumulating in the pipeline, so that the content of impurities in the liquid in the pipeline is reduced, thereby improving the quality of the liquid transported by the pipeline.

[0043] Specifically, the filter assembly 9 includes a filter cartridge 91, a first three-way valve 92, and a second three-way valve 93. One interface of the first three-way valve 92 and the second three-way valve 93 are both connected to the liquid inlet pipe 32. The number of filter cartridges 91 is two. The three interfaces of the first three-way valve 92 are respectively an A interface 921, a B interface 922, and a C interface 923. The three interfaces of the second three-way valve 93 are respectively a D interface 931, an E interface 932, and an F interface 933. The A interface 921 and the D interface 931 are respectively connected to the liquid inlet pipe 32, and the B interface 922 and the E interface A filter cartridge 91 is respectively connected between 932 and between the C interface 923 and the F interface 933. The liquid in the liquid inlet pipe 32 enters the filter cartridge 91 through the first three-way valve 92 for filtration and is then discharged from the second three-way valve 93. When replacing the filter cartridge 91, the two three-way valves are adjusted so that one of the filter cartridges 91 is in a conducting state and the other filter cartridge 91 is in a closed state. The closed filter cartridge 91 is removed and replaced. In this way, when replacing the filter cartridge 91, the oil inlet pipe is always in a conducting state, avoiding closing the valve when replacing the filter cartridge 91 to reduce the pipeline transportation efficiency.

[0044] An optional implementation of this embodiment is as follows: a manual regulating valve 10 is also provided on the above-mentioned liquid inlet pipe 32, and the manual regulating valve 10 is arranged outside the box body 1. When the controller 8 is damaged or the power is cut off, the manual regulating valve 10 is closed or the flow in the liquid inlet pipe 32 is changed by adjusting the manual regulating valve 10, so that the pressure in the pipeline is at a safe value, which is safer to use.

[0045] An optional implementation of this embodiment is as follows: a heat sink 4 is pasted on the above-mentioned box cover 2, and the controller 8 is installed on the heat sink 4. The heat sink is attached to the box cover 2. The controller 8 generates heat when receiving and analyzing the data transmitted by the flow meter 5 and the pressure sensor 6 in real time and adjusting the control valve. The heat sink 4 is used to absorb and transfer the heat generated by the controller 8 to the box body 1. The heat is dissipated through the outer wall of the box body 1, which has a better heat dissipation effect on the controller 8.

[0046] An optional implementation of the present embodiment is as follows: a square hole is provided on the outer wall of the above-mentioned box body 1, and a louvered heat sink 11 is provided in the square hole. The heat in the box body 1 can be dissipated through the gaps between the louvered heat sinks 11. At the same time, since the louvered heat sink 11 is a plurality of downwardly inclined plates, when liquid flows down on the box body 1, the liquid is repelled from the outside of the box body 1 by the plates, so that the inside of the box body 1 is relatively dry. More preferably, multiple groups of louvered heat sinks 11 are used, and multiple groups of louvered heat sinks 11 have a better heat dissipation effect on the inside of the box body 1 and a better use effect.

[0047] An optional implementation of this embodiment is as follows: the test manifold 3 automatic control equipment also includes an exhaust fan 12, the exhaust fan 12 is installed on the side wall of the box body 1, and a mounting frame 13 corresponding to the square hole is provided on the inner wall of the box body 1. The exhaust fan 12 is installed on the mounting frame 13, and the position of the exhaust fan 12 is directly opposite to the louver heat sink 11. The exhaust fan 12 is used to discharge the gas inside the box body 1 to the outside of the box body 1 to reduce the internal temperature of the box body 1. At the same time, since the liquid in the pipeline is oil, part of the oil and gas evaporates inside the box body 1 during maintenance or long-term use. The exhaust fan 12 reduces the temperature and discharges the oil and gas to the outside of the box body 1 at the same time, reducing the possibility of safety hazards during use.

[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
