Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure:

1-handwheel, 2-valve rod, 3-supporting base, 4-valve gap, 5-valve body, 6-spool, 7-temp probe, 8-pH counts probe, 9-control panel, 10-alarm, 11-drive unit, 12-drived control single-chip microcomputer, 13-wireless signal transceiver, 14-drying device.

Embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated.

As shown in Figure 1, a kind of self-control safety valve of the present utility model, comprises handwheel 1, valve rod 2, supporting base 3, valve gap 4, valve body 5, spool 6, temp probe 7, pH meter probe 8, control panel 9, alarm 10, drive unit 11, drived control single-chip microcomputer 12, wireless signal transceiver 13, drying device 14;

Valve gap 4 is arranged on above valve body 5, and the top of valve gap 4 is fixed with supporting base 3, handwheel 1 is arranged on the top of valve rod 2, the other end of valve rod 2 is through supporting base 3, it is inner that valve gap 4 extends to valve body 5, and the bottom of valve rod 2 is provided with the spool 6 of regulation valve body 5 working state, position near top on valve rod 2 is provided with drying device 14, valve body 5 inside is provided with temp probe 7, pH meter probe 8, valve body 5 outside is provided with control panel 9, control panel 9 respectively with temp probe 7, pH meter probe 8 is by electrical connection, valve body 5 is also provided with alarm 10, wireless signal transceiver 13, wireless signal transceiver 13 and alarm 10 are by electrical connection, alarm 10 respectively with temp probe 7, pH meter probe 8 is by electrical connection, handwheel 1 is provided with drive unit 11, drive unit 11 is provided with drived control single-chip microcomputer 12, drived control single-chip microcomputer 12 respectively with temp probe 7, pH meter probe 8, wireless signal transceiver 13 is by electrical connection.
