Background
The existing liquid level control device mainly comprises a glass liquid level meter and a magnetic floater liquid level meter, wherein the glass liquid level meter is easy to fail due to the fact that a probe is in contact with a medium and is affected by scaling or corrosion, and liquid level control is inaccurate. Therefore, the magnetic float liquid level meter is more suitable to be used as a liquid level control device in the roller type vulcanization steam generator.
The existing magnetic float level meter generally comprises a magnetic float arranged in a non-magnetic cylinder and a magnetic overturning indicating sheet arranged outside the non-magnetic cylinder, wherein the magnetic float is driven to ascend or descend through the liquid level in the cylinder so as to overturn the overturning indicating sheet at different positions to display a reading, but the magnetic level meter can only display liquid level data and does not have the function of controlling the liquid level. In order to meet the requirement of controlling the liquid level, a liquid level detector is required to be added on the liquid storage tank, and the liquid level detector informs a liquid level control system of a detected liquid level signal, so that the liquid level control system controls the liquid level in the liquid storage tank. However, the existing magnetic float level meter is generally provided with only one liquid level detector, and the liquid level detection and control functions are limited. And the liquid level detector is fixedly arranged on the liquid level meter body, and can not adapt to the detection requirements of different working conditions.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The liquid level control device of the roller type vulcanizing steam generator shown in the figures 1-5 comprises a body 1, wherein an upper connecting pipe 2 and a lower connecting pipe 3 are respectively arranged at the top end and the lower end of the body, a magnetic turnover piece 4 is axially arranged on the outer surface of the body, a magnetic floater 5 is arranged in the inner cavity of the body, the magnetic floater moves up and down along with the lifting of the liquid level in the body, the magnetic floater drives the magnetic turnover piece to turn over through the magnetic coupling effect, an installation plate 6 is arranged on the outer surface of the body, an upper limit switch 7, a middle limit switch 8 and a lower limit switch 9 which are electrically connected with a liquid level control system are arranged on the installation plate, the upper limit switch, the middle limit switch and the lower limit switch are magnetically coupled with the magnetic floater, and the installation positions of the upper limit switch, the middle.
6 surfaces of mounting panel be provided with guide rail 10, be provided with the spout with the guide rail intercommunication in the mounting panel, bilateral symmetry at the guide rail sets up multiunit through-hole 11, goes up limit switch 7 and sets up connecting rod 12 and connecting plate 13, the one end of connecting rod sets up limit switch, the other end sets up the connecting plate, one side both ends of connecting plate 13 set up the marble 14 that can pass the through-hole, well limit switch is the same with lower limit switch's structure with last limit switch.
