Description
Technical field
The utility model relates to a kind of gas circuit control module, is applicable to SF6Gas purity instrument carries out gas pressure measurement, flow control and measurement.
Background technology
SF6Gas, with its good insulating property and arc extinction performance, is widely used in electrical equipment industry. Because of SF6The insulation characterisitic of gas is very big by impurity effect, it is necessary to the often purity of measurement gas, causes SF6The heavy demand of gas purity analyser. Owing to measuring SF6Require during gas purity to lead to into gas keep stable flow, for preventing the fluctuation of gas flow from causing measuring result to produce error, it is necessary to the block coupled in series of a kind of control and measurement gas flow, measuring in pipeline, also should be able to measure gas circuit and bleed pressure simultaneously.
Summary of the invention
1, goal of the invention
The purpose of this utility model is simple in order to design a kind of structure, is convenient to the gas circuit control module installed, it is possible to stable control and measurement gas flow, and can measure gas source and measure the pressure of gas circuit, is SF6The measurement of gas purity instrument provides reliable tested air-flow.
2, technical scheme
Task of the present utility model is implemented as follows: it by material be 304 valve island (1) as pedestal, tested gas is by inlet pipe (12), inlet pipe joint (11) enters valve island (1), it is connected through valve island (1) internal duct and enters electromagnetic proportional valve (10), then by measuring front joint (9), measurement inlet pipe (8) enters measurement module (7) and measures, measurement terminate after by measuring tracheae (6), after measuring, joint (4) enters valve island (1), enter under meter (2) through the connection of valve island (1) internal duct and enter two-bit triplet magnetic valve (14) again, then discharge through exhaust joint (3) and vapor pipe (5), when carrying out gas detection, pressure transmitter (13) Real-Time Monitoring measures gaseous tension in pipeline, under meter (2) Real-Time Monitoring gas flow also can pass through electromagnetic proportional valve (10) and regulate, ensure to measure and carry out under same stable flow, when two-bit triplet magnetic valve (14) blocks gas circuit, bleed pressure is measured by pressure transmitter (13).Under meter (2), electromagnetic proportional valve (10), pressure transmitter (13) and two-bit triplet magnetic valve (14) are arranged on same Jian Fa island (1), have been connected gas pressure measurement, flow control and measurement function by valve island internal duct.

3, technique effect
The utility model has following advantage compared with the prior art
1) comprehensive: under meter (2), electromagnetic proportional valve (10), pressure transmitter (13) and two-bit triplet magnetic valve (14) are arranged on same Jian Fa island (1), gas pressure measurement, flow control and measurement function are concentrated, save space, convenient installation.
2) the ingenious connection of valve island (1) internal openings, reduces joint consumption, shortens gas circuit length, reduces waste of material.
Four, accompanying drawing explanation
Fig. 1 is the utility model wiring layout.
Five, embodiment
Below in conjunction with accompanying drawing, example of the present utility model is described in detail.
Electromagnetic proportional valve (10) and pressure transmitter (13) are installed on the adjacent facets of valve island (1), and electromagnetic proportional valve (10) production well is connected with pressure transmitter (13) open holes, and are connected with joint (9) open holes before measurement, electromagnetic proportional valve (10) air inlet port is connected with inlet pipe joint (11) open holes. tested gas enters valve island (1) by inlet pipe joint (11), flow through electromagnetic proportional valve (10) air inlet port and enter electromagnetic proportional valve (10), electromagnetic proportional valve (10) can adjusting gas flow, gas through the production well of electromagnetic proportional valve (10) enter measure before joint (9), it is connected pressure transmitter (13) simultaneously, can the tested airline pressure of Real-Time Monitoring, then gas through measure inlet pipe (8) enter measure module (7) measure, measurement terminate after by measuring tracheae (6), after measuring, joint (4) enters valve island (1), after measuring, joint (4) open holes is connected with under meter (2) air inlet port, under meter (2) production well is connected with two-bit triplet magnetic valve (14) air inlet port, two-bit triplet magnetic valve (14) and under meter (2) are installed on the adjacent facets of valve island (1) respectively. two-bit triplet magnetic valve (14) is often opened hole and is connected exhaust joint (3) open holes, and normally closed path blocks. during normal measurement, tested gas is discharged through exhaust joint (3) and vapor pipe (5), and under meter (2) can carry out flow measurement and carry out flow adjustment by electromagnetic proportional valve (10). measuring gas circuit when two-bit triplet magnetic valve (14) cuts out and often opens road to end at two-bit triplet magnetic valve (14) place, now pressure transmitter (13) can measure bleed pressure.
This gas circuit control module manufactures, assembling is simple, is easy to operation, it is possible to carry out gas pressure measurement, flow control and measurement easily.
