Embodiment Construction

[0017] The following reference figure 1 In the figure, 101: reference cup, 102: gate, 103: notch, 104: fixed pulley, 106: rope body, 107: support frame, 108: liquid level, 109: floating body.

[0018] In this invention, a notch 103 is provided on the wall of the condensed water reference cup 101. The notch 103 is provided with a gate 102 that slides up and down along the notch 103. A floating body 109 is provided in the reference cup 101. The gate 102 utilizes a rope 106 is connected with the floating body 109 through the fixed pulley 104, and the fixed pulley is arranged on the support frame 107. The rise or fall of the floating body 109 drives the gate 102 to fall or rise to adjust the liquid level of the reference cup 101, and the condensed water reference cup wall 101 There may also be two gaps on the top, and the two gaps are respectively provided with gates 102 that slide up and down along the gaps. The gates 102 are connected to the floating body through a fixed pulley...

Abstract

The invention discloses a temperature compensation type boiler steam drum liquid level gauge, which belongs to the field of boiler liquid level measuring equipment. The liquid level gauge includes a condensed water reference cup, a notch is provided on the wall of the condensed water reference cup, and a gate slidingly connected up and down along the notch is provided on the notch, and a floating body is arranged in the reference cup, and the gate uses a rope The body is connected with the floating body through a fixed pulley, and the rising or falling of the floating body drives the gate to fall or rise to adjust the liquid level of the reference cup. This technical solution changes the pressure change caused by the change of water density in the reference cup by adjusting the height of the reference cup. Phenomenon, by fine-tuning the height of the reference cup with the gate, the pressure in the reference cup can always be kept constant.

Description

technical field [0001] The invention relates to a boiler steam drum liquid level gauge, in particular to a temperature compensation type boiler steam drum liquid level gauge, which belongs to the field of boiler liquid level measuring equipment. Background technique [0002] The steam level of the boiler drum is a very important monitoring parameter for the safe operation of the boiler in the power plant, and maintaining the normal liquid level of the steam drum is a necessary condition to ensure the safe operation of the boiler. Monitoring and adjusting the liquid level of the steam drum is an important job for the operator. If the monitoring and adjustment are not timely, it will affect the safe and stable operation. If the liquid level is too high or too low, it will cause the deterioration of water vapor quality and even cause accidents, which not only affects the economic benefits of the enterprise, but also poses a great threat to the safe operation of equipment. Moni...
