The first pipeline 51 and the second pipeline 52; the first oxygen shut-off valve 1 is located at the inlet end of the first pipeline 51; the front end of the filter 2 is connected to the first oxygen shut-off valve 1; The rear end of the filter 2 is connected to the front end of the pressure regulating valve 3; the rear end of the pressure regulating valve 3 is connected to the second oxygen shut-off valve 4;
其中，所述第一氧气截止阀1的入口端与所述第一管道51的入口端连接，所述第一氧气截止阀1的出口端与所述过滤器2的前端连接，当氧气高进低出时，第一氧气截止阀1的氧气的作用力与阀杆的作用力之和大于0，可保证第一管道51保持密封；所述第二氧气截止阀4的入口端与所述第二管道52的出口端连接，所述第二氧气截止阀4的出口端与所述调压阀3的后端连接，当氧气低进高出时，第二氧气截止阀4的氧气的作用力与阀杆的作用力之和大于0，可保证第二管道52的出口端保持密封。Wherein, the inlet port of the first oxygen shut-off valve 1 is connected to the inlet port of the first pipeline 51, and the outlet port of the first oxygen shut-off valve 1 is connected to the front end of the filter 2. When it is low, the sum of the oxygen force of the first oxygen stop valve 1 and the force of the valve stem is greater than 0, which can ensure that the first pipeline 51 remains sealed; the inlet port of the second oxygen stop valve 4 is connected to the first The outlet ends of the two pipelines 52 are connected, and the outlet end of the second oxygen shut-off valve 4 is connected to the rear end of the pressure regulating valve 3. The sum of the acting forces with the valve stem is greater than 0, which can ensure that the outlet end of the second pipe 52 remains sealed.
为了保证密封效果，所述第一氧气截止阀为大口径截止阀,口径大于等于DN250；所述第二氧气截止阀为大口径截止阀,口径大于等于DN250。In order to ensure the sealing effect, the first oxygen shut-off valve is a large-diameter shut-off valve with a diameter greater than or equal to DN250; the second oxygen shut-off valve is a large-diameter shut-off valve with a diameter greater than or equal to DN250.
进一步地，氧气送管网装置的送出压力在10bar以上。Further, the delivery pressure of the oxygen supply pipe network device is above 10 bar.
本实施例中氧气送管网装置的工作流程如下：The workflow of the oxygen delivery pipe network device in this embodiment is as follows:
氧气从第一管道51的入口端进入氧气送管网装置，打开第一氧气截止阀1，氧气通过第一氧气截止阀1进入第一管道51，再经过过滤器2将氧气中的杂质清除，通过调压阀3调节第二管道52中的压力，再经第二氧气截止阀通往第二管道52的出口端，从而完成氧气的送出流程，其中第一氧气截止阀为DN350口径氧气截止阀，第二氧气截止阀为DN500口径氧气截止阀，本实施例中氧气管网压力为30bar，可计算得出DN500口径的截止阀4的氧气的第一作用力F1为58.875吨，阀杆的第二作用力F2为3.06吨，密封所需要的第三作用力F3为0.345吨，若不采用本氧气送管网装置，当氧气低进高出时，F2与F1之差远小于密封所需要的力，所以不能保证密封；而本实施例提供的氧气送管网装置中，当调压阀3发生故障时，可以关闭第一氧气截止阀1和第二氧气截止阀4,，并将调压阀3处于泄压状态，根据氧气截止阀自身密封原理，由于第二氧气截止阀4的入口端与所述第二管道52的出口端连接，第二氧气截止阀4的出口端与所述调压阀3的后端连接，第二氧气截止阀4连接的第二管道52中的氧气为高进低处，F1与F2作用力之和远大于密封所需要的力，因此第二氧气截止阀4能保证第二管道52的密封，则第二氧气截止阀4连接的第二管道52中的氧气不会泄漏，有效地保证了第一管道51和第二管道52的密封，保证了空分稳定运行。Oxygen enters the oxygen supply pipe network device from the inlet end of the first pipeline 51, opens the first oxygen shut-off valve 1, oxygen enters the first pipeline 51 through the first oxygen shut-off valve 1, and then passes through the filter 2 to remove impurities in the oxygen, Adjust the pressure in the second pipeline 52 through the pressure regulating valve 3, and then lead to the outlet end of the second pipeline 52 through the second oxygen shut-off valve, so as to complete the sending process of oxygen, wherein the first oxygen shut-off valve is an oxygen shut-off valve with a diameter of DN350 , the second oxygen shut-off valve is DN500 caliber oxygen shut-off valve. In this embodiment, the pressure of the oxygen pipe network is 30 bar. It can be calculated that the first force F1 of oxygen in the DN500 caliber shut-off valve 4 is 58.875 tons, and the first action force F1 of the valve stem is 58.875 tons. The second force F2 is 3.06 tons, and the third force F3 required for sealing is 0.345 tons. If this oxygen delivery pipe network device is not used, when the oxygen is low in and high out, the difference between F2 and F1 is much smaller than that required for sealing Therefore, the sealing cannot be guaranteed; and in the oxygen supply pipe network device provided in this embodiment, when the pressure regulating valve 3 fails, the first oxygen shut-off valve 1 and the second oxygen shut-off valve 4 can be closed, and the pressure can be adjusted The valve 3 is in a pressure relief state. According to the self-sealing principle of the oxygen shut-off valve, since the inlet end of the second oxygen shut-off valve 4 is connected to the outlet end of the second pipeline 52, the outlet end of the second oxygen shut-off valve 4 is connected to the outlet port of the regulating valve 4. The rear end of the pressure valve 3 is connected, and the oxygen in the second pipeline 52 connected to the second oxygen shut-off valve 4 is high and low, and the sum of the forces of F1 and F2 is much greater than the force required for sealing, so the second oxygen shut-off valve 4 can ensure the sealing of the second pipeline 52, then the oxygen in the second pipeline 52 connected with the second oxygen shut-off valve 4 will not leak, effectively ensuring the sealing of the first pipeline 51 and the second pipeline 52, and ensuring air separation Stable operation.
与现有技术相比，本实用新型提供的氧气送管网装置具有以下优点和有益效果：Compared with the prior art, the oxygen supply pipe network device provided by the utility model has the following advantages and beneficial effects:
通过第一氧气截止阀和第二氧气截止阀，并且第二氧气截止阀的入口端与第二管道的出口端连接，第二氧气截止阀的出口端与调压阀的后端连接，在调压阀处于泄压状态时，第一氧气截止阀和第二氧气截止阀能保证氧气送管网装置的两端完全密封，使空分稳定地运行。Through the first oxygen shut-off valve and the second oxygen shut-off valve, and the inlet end of the second oxygen shut-off valve is connected with the outlet end of the second pipeline, and the outlet end of the second oxygen shut-off valve is connected with the rear end of the pressure regulating valve. When the pressure valve is in the pressure relief state, the first oxygen shut-off valve and the second oxygen shut-off valve can ensure that the two ends of the oxygen supply pipe network device are completely sealed, so that the air separation can run stably.
