Description
技术领域 technical field
本发明涉及一种气体切换柜，具体涉及一种定量式气体自动切换柜。 The invention relates to a gas switching cabinet, in particular to a quantitative gas automatic switching cabinet.
背景技术 Background technique
切换柜是专门用于气体供气的装置，该装置要保证气体供气的均匀性和连续性，还要保证输出气体是稳压状态的，且不会因为输出流量过大导致钢瓶里的气体气化量不足从而使钢瓶内的压力过低导致切换到另一路，使钢瓶内部的气体使用不净造成极大的浪费。为满足目前的使用需求，对切换柜的精度性和气体输出的稳定性和安全性提出了较高的要求，但是现有的切换柜在上述问题上均存在严重的缺陷，无法满足上述要求，在实际生产过程中，为了避免由于钢瓶气化量不足而影响生产，因钢瓶内的气体使用不净极大的提高了企业的支出，严重影响企业资金运转，需要改进。 The switching cabinet is a device specially used for gas supply. The device must ensure the uniformity and continuity of the gas supply, and also ensure that the output gas is in a stable state, and will not cause the gas in the cylinder to flow due to excessive output flow. Insufficient gasification volume makes the pressure in the steel cylinder too low, which leads to switching to another way, which makes the use of the gas inside the cylinder unclean and causes great waste. In order to meet the current use requirements, higher requirements are put forward for the accuracy of the switching cabinet and the stability and safety of the gas output. However, the existing switching cabinets have serious defects in the above problems and cannot meet the above requirements. In the actual production process, in order to avoid the impact of production due to insufficient gasification of steel cylinders, the unclean use of gas in steel cylinders greatly increases the company's expenditure and seriously affects the company's capital operation, which needs to be improved.

下面结合附图和具体实施方式对本发明作进一步详细的说明。 The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
附图是本发明的一种具体实施方式。该实施例包括主管路1和分别与主管路1连通的A管路系统2、B管路系统3和C管路系统4，所述主管路1上连接有电子质量流量计5；所述A管路系统2、B管路系统3和C管路系统4均包括通过管路依次连接的气体输入阀门7、压力变送器8和电磁阀10和单向止回阀9；A管路系统2、B管路系统3和C管路系统4分别在压力变送器8与主管路1之间设有旁通管路12，旁通管路12上设有旁通阀门11；所述电子质量流量计5与主管路1之间设有调压阀6；所述A管路系统2、B管路系统3和C管路系统4以及电子质量流量计5分别与PLC控制器连接。 Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises main pipeline 1 and A pipeline system 2, B pipeline system 3 and C pipeline system 4 that communicate with main pipeline 1 respectively, and described main pipeline 1 is connected with electronic mass flow meter 5; Piping system 2, B piping system 3 and C piping system 4 all include a gas input valve 7, a pressure transmitter 8, a solenoid valve 10 and a one-way check valve 9 connected sequentially through the pipeline; A piping system 2. The B pipeline system 3 and the C pipeline system 4 are respectively provided with a bypass pipeline 12 between the pressure transmitter 8 and the main pipeline 1, and the bypass pipeline 12 is provided with a bypass valve 11; A pressure regulating valve 6 is provided between the mass flowmeter 5 and the main pipeline 1; the A pipeline system 2, the B pipeline system 3 and the C pipeline system 4 and the electronic mass flowmeter 5 are respectively connected to the PLC controller.
本实施例通过A、B、C三路不同气体管路根据累计流量进行切换。 In this embodiment, three different gas pipelines A, B, and C are switched according to the cumulative flow.
首先使用A管路系统2送气，在正常情况下A管路系统2、B管路系统3和C管路系统4的旁通阀门11处于关闭状态，系统送电后，通过PLC控制器设定的程序，PLC可编程控制器通过A管路系统2的压力变送器8读取A路输入管路的压力数值，当A路输入管路的气体压力在满足使用压力要求的情况下PLC可编程控制器打开电磁阀10让A管路系统2首先供气，电子质量流量计5开始测量供气的瞬时流量，传输到PLC，PLC内部计算A管路系统2气体的供气累计流量，当累计流量≥50m3时，在B管路系统3的气体压力在满足使用压力要求的情况下PLC可编程控制器关闭A管路系统2的电磁阀10，打开B管路系统3的电磁阀10把A路气体切换到B路气体供气。 First, use A pipeline system 2 to supply air. Under normal circumstances, the bypass valves 11 of A pipeline system 2, B pipeline system 3 and C pipeline system 4 are closed. After the system is powered on, it is set by the PLC controller. Program, the PLC programmable controller reads the pressure value of the input pipeline of the A pipeline through the pressure transmitter 8 of the A pipeline system 2. When the gas pressure of the A pipeline input pipeline meets the operating pressure requirements, the PLC can The programming controller opens the solenoid valve 10 to let the A pipeline system 2 supply gas first, and the electronic mass flowmeter 5 starts to measure the instantaneous flow rate of the gas supply, and transmits it to the PLC. The PLC internally calculates the gas supply cumulative flow rate of the A pipeline system 2 gas. When the cumulative flow rate is ≥ 50m 3 , when the gas pressure of the B pipeline system 3 meets the operating pressure requirements, the PLC programmable controller closes the solenoid valve 10 of the A pipeline system 2 and opens the solenoid valve 10 of the B pipeline system 3 Switch the gas from channel A to the gas supply from channel B.
B管路系统3开始供气后，PLC自动切换到计算B管路系统3气体的供气累计流量，当累计流量≥50m3时，在C管路系统4的气体压力在满足使用压力要求的情况下PLC可编程控制器关闭B管路系统3的电磁阀10，打开C管路系统4的电磁阀10把B路气体切换到C路气体供气。 After the B pipeline system 3 starts to supply gas, the PLC automatically switches to calculate the gas supply cumulative flow of the B pipeline system 3 gas. When the cumulative flow rate is ≥ 50m 3 , the gas pressure in the C pipeline system 4 meets the operating pressure requirements. Under the circumstances, the PLC programmable controller closes the electromagnetic valve 10 of the B pipeline system 3, and opens the electromagnetic valve 10 of the C pipeline system 4 to switch the B-channel gas to the C-channel gas supply.
C管路系统4开始供气后，PLC自动切换到计算C管路系统4气体的供气累计流量，当累计流量≥50m3时，再次切换到A管路系统2供气，依次循环下去。 After C pipeline system 4 starts gas supply, PLC automatically switches to calculate the gas supply cumulative flow rate of C pipeline system 4 gas supply. When the cumulative flow rate is ≥ 50m3, it switches to A pipeline system 2 gas supply again, and the cycle continues in turn.
当在停电状态下，可手动打开旁通管路12上的旁通阀门11进行供气。单向止回阀9是防止供气中管路的气体通过主管路1进入到未供气管路中的止回装置，安装此装置后使电子质量流量计5更准确的记录每一路供气管路的流量值。 When in a power failure state, the bypass valve 11 on the bypass pipeline 12 can be manually opened for gas supply. The one-way check valve 9 is a check device that prevents the gas in the gas supply pipeline from entering the unsupplied pipeline through the main pipeline 1. After installing this device, the electronic mass flowmeter 5 can record each gas supply pipeline more accurately flow value.
