Abstract

The invention provides an anti-freezing liquid level meter device for a water jacket furnace, and relates to a liquid level meter. One side of a water pot is provided with the liquid level meter, thetwo ends of the liquid level meter are provided with communication valves, the liquid level meter is inserted into the water pot through a valve seat at the front ends of the communication valves at the two ends to achieve the connection with the water pot, the liquid level meter is provided with multiple control valves, the communication valves and the two ends of valve rods in the control valvesare provided with double-seal screw rods compressed and sealed by non-metallic packing respectively, heating insulation sleeves adapted to the control valves sleeve the outer portions of the controlvalves respectively, and an anti-freezing liquid is placed in an oil-water diaphragm in a container. The anti-freezing liquid level meter device for the water jacket furnace has the advantages that not only can freezing prevention of a liquid in a glass liquid level meter and freezing prevention of the insertion type connection of the communication valves in liquid level monitoring of the water jacket furnace be achieved, but also the effective heating insulation anti-freezing protection of each control valve can be achieved, the anti-freezing and anti-blocking effects are excellent, and the anti-freezing liquid level meter device is applied to the outdoor oilfield production in north China, can play a great role, and ensures the safety of the oilfield production.

Description

technical field [0001] The invention relates to a liquid level gauge, in particular to a water boiler jacket antifreeze liquid level gauge device. Background technique [0002] As is well known, in the oil field production process, the water jacket furnace is referred to as the water jacket furnace for short, and is often used to heat crude oil to remove the water therein. When the water jacket furnace is used for heating, in order to avoid the water jacket furnace from drying out, the oil-water container liquid level indicator is often used to monitor the water level inside the water jacket furnace. The water level should be 1 / 2-2 / 3 of the display range of the liquid level gauge between. When the water level is below the minimum safe water level mark, water should be added, and when it exceeds the maximum safe water level, the excess water should be drained. The ability of the liquid level gauge to accurately reflect the internal liquid level of the water jacket boiler i...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, in the process of oil field production, the level gauge used in the water jacket furnace often suffers from the problem of freezing and blocking, and there is an urgent need for an antifreeze liquid level gauge device for the water jacket furnace, which can be used in oil field production;

[0004] 2. During the use of the currently used glass tube level gauge, the water in the glass tube in the level gauge connected to the water jacket furnace will often freeze, and the freezing will burst the glass tube, and will cause water in the jacket furnace. Water overflows, affecting the normal operation of the water jacket furnace;

[0005] 3. Causes of freezing blockage: The connection valves used at the upper and lower connections between the water jacket furnace and the glass tube liquid level gauge are installed outside the water jacket furnace body, and the connection valves are not equipped with corresponding antifreeze protection measures, resulting in freezing blockage and affecting oil field production the conduct of work;

[0006] 4. In the process of connecting the glass level gauge and the water jacket furnace, the shut-off valves used generally include needle valves, gate valves or ball valves, but the valve stems of these valves are all single-way sealed. Compared with the other end of the seal , because no sealing measures are taken, oil and water can easily enter the gap between the screw rod and the screw thread of the valve and cause freezing and blockage, which will affect the production work in the oil field;

[0007] 5. There is often some oil and water in the pipe connecting the water jacket furnace and the glass liquid level gauge and the pipe of the glass liquid level gauge. Because the temperature in the north is low in winter, people do not empty the oil and water in the pipe after observing the liquid level. It is easy for oil and water to freeze in the pipeline, so that the glass level gauge cannot observe the real liquid level in the water jacket furnace normally, resulting in the phenomenon of heating and drying the pot, and even serious safety problems of explosion;

[0008] 6. Once the freezing problem of the glass tube liquid level gauge occurs, the liquid level displayed by the liquid level gauge cannot correctly reflect the real situation of the liquid level inside the water jacket furnace. There are water shortages in the water jacket furnace and exposed coils inside the furnace body. The problem on the water surface in the furnace leads to poor heating efficiency of the water jacket furnace, reduces oil field production efficiency, and also exacerbates the coil corrosion problem
