Problems solved by technology

[0002] A resistance level gauge is often used to measure the height of the liquid. When the boiler is used to process the liquid, the level gauge is installed inside the boiler. The electrical contact of the level gauge is one electrode, and the inner wall of the boiler is used as the other electrode. When the liquid rises to a certain height of the level gauge, the water molecules in the liquid conduct electricity and make the electric contact energized lamp bead emit light; in the prior art, when the resistance level gauge is used to measure the height of the liquid, since the electric contact is set horizontally After the height of the liquid drops, the discharge speed of the liquid inside the tube of the electrical contact is slow. After the liquid level rises again, the level gauge is slightly vibrated by the thrust of the liquid, the liquid inside the tube flows, and the liquid contacts the electrical contact, while the liquid There is a small amount of current in the liquid, which causes the electric contact to be energized and prompts, resulting in errors in the process of liquid height measurement

Embodiment 2

[0034] as attached Figure 6 to attach Figure 7 Shown:

[0035] Wherein, the clamping plate a2 is provided with a support plate r1, a drainage groove r2, and a drain hole r3, the drainage groove r2 is recessed on the upper surface of the support plate r1, and the drain hole r3 runs through the upper and lower surfaces of the support plate r1, and is connected to the upper surface of the support plate r1. The drainage groove r2 is connected, and the drainage groove r2 is inclined from the outside to the middle, which is beneficial to reduce the resistance to the liquid and accelerate the flow of the liquid along the slope into the drain hole r3. The drain hole r3 is provided with eight One, it is beneficial to speed up the flow of liquid along the drain hole r3, slow down the gravity of the clamping plate a2, and further accelerate the moving speed of the pushing mechanism 15 up and down.

[0036] Wherein, the drainage hole r3 is provided with a drainage hole t1, a groove t2, ...

Abstract

The invention discloses a resistance type level instrument with an adjustable dielectric resistance area, which structurally comprises a pipe body, a fixed flange and a liquid discharge pipe, the fixed flange is horizontally welded on the back surface of the pipe body, and the liquid discharge pipe is vertically arranged at the bottom end of the pipe body. After the height of the liquid is reduced, the discharging speed of the liquid in a liquid inlet pipe of the electric contact is low, liquid in the liquid inlet pipe is pushed to the right end of the liquid inlet pipe through airflow diffusion in an elastic ring of a pushing mechanism, liquid retention in the liquid inlet pipe is reduced, flowing of the liquid in the pipe is reduced, contact between the liquid and an electric contact isreduced, the electric contact is powered on to give a prompt due to a small amount of current in the liquid, and liquid height measurement is facilitated. Due to the fact that liquid stays on the outer wall of the elastic ring, the bearing capacity of the pushing mechanism is increased, the moving speed is reduced, the liquid staying on the outer wall of the elastic ring is drained and dischargedthrough the liquid discharging holes of the clamping plate, the bearing capacity of the pushing mechanism is better reduced, the moving speed of the pushing mechanism is increased, and pushing and discharging of the liquid in the liquid inlet pipe are accelerated.
