Description

Technical Field

[0001] The invention relates to a self-conducting hot water jacket furnace liquid level gauge, belonging to the technical field of liquid level gauges. Background Art

[0002] When the water jacket furnace is used for heating, in order to prevent the water jacket furnace from drying out, a liquid level gauge is often used to monitor the water level inside the water jacket furnace. The water level should be between 1 / 2-2 / 3 of the liquid level gauge display range. When the water level is below the minimum safe water level mark, water should be added. When it exceeds the maximum safe water level, the excess water should be drained. The liquid level gauge can accurately reflect the liquid level inside the water jacket furnace, which is one of the guarantees for ensuring safe production in the oil field.

[0003] At present, the level gauges of water jacket heating furnaces used in oil fields mostly adopt glass tube level gauges and magnetic plate level gauges. Among them, the glass tube level gauge is easy to freeze in winter, and the connecting pipe between the control valve of the glass tube level gauge and the water jacket furnace body is too long, which is easy to freeze and block. When checking the liquid level in winter, the upper and lower valves of the level gauge should be opened, and the valve should be closed and the water should be drained after viewing. The temperature difference is often large, causing the glass tube to burst, causing the water in the water jacket furnace to overflow, affecting the normal operation of the water jacket furnace. The temperature in the north is low in winter, and it is easy for oil and water to freeze in the pipeline, so that the glass level gauge cannot normally observe the real liquid level in the water jacket furnace, resulting in the phenomenon of heating and drying the pot, and even serious safety problems such as explosion. After a long time of use, the magnetic plate level gauge will be demagnetized, the liquid level display will be inaccurate, and the level gauge will be frozen due to the long connecting pipe. The solar heating level gauge relies on solar energy to heat the level gauge, and is subject to the influence of the intensity of sunlight, and the antifreeze effect is poor. Summary of the invention

[0004] The invention aims to solve the problem that the glass tube level gauge and magnetic plate level gauge used in the water jacket heating furnace in oil field production often freeze in winter and the problem that the operation of observing the level gauge is complicated and the observation is inaccurate.

[0005] The technical solution of the present invention is: a self-conducting water jacket furnace liquid level gauge, comprising an arc-shaped liquid level gauge located on the outer wall of the arc-shaped water jacket furnace, the curvature of the liquid level gauge coincides with the curvature of the outer wall of the water jacket furnace, a transparent window for observing the liquid level is provided on the surface of the liquid level gauge, the upper and lower ends of the liquid level gauge are detachably fixed on the outer wall of the water jacket furnace through a connecting device, the liquid level gauge is connected to the connecting device, the connecting device is connected to a connecting pipe, and the connecting pipe is connected to the inner cavity of the water jacket furnace.

[0006] A magnet is fixed on the connection surface between the liquid level meter and the outer wall of the water jacket furnace, and the liquid level meter is attracted to the outer wall of the water jacket furnace through the magnet.

[0007] The magnet has a curvature, and the curvature of the magnet matches the curvature of the outer wall of the attracted water jacket furnace.

[0008] A control valve is arranged on the connecting pipe.

[0009] The connecting device comprises connecting blocks fixed to the upper and lower ends of the liquid level meter, and the connecting blocks are fixed to the outer wall of the water jacket furnace through connecting rods and nuts.

[0010] A through hole is opened on the side of the connecting rod, a through hole b is opened on the connecting block, the through hole a is connected with the inner cavity of the liquid level meter through the through hole b, and the connecting rod is connected with the connecting pipe.

[0011] The connecting block comprises an upper connecting block fixed at the upper end of the liquid level gauge, and a lower connecting block fixed at the lower end of the liquid level gauge. The lower connecting block is provided with a pressure relief hole connected to the inner cavity of the liquid level gauge. The pressure relief hole is connected to a pressure relief pipe, and a pressure relief valve is provided on the pressure relief pipe.

[0012] The connecting rod passes through the connecting block, the nuts are located on both sides of the connecting block and are threadedly connected to the connecting rod, and a sealing gasket is provided between the nuts and the connecting block.

[0013] The beneficial effects of the present invention are:

[0014] (1) The liquid level gauge is fixed on the outer wall of the water jacket furnace. The heat on the outer wall of the water jacket furnace can be transferred to the liquid level gauge, so that the temperature of the liquid in the liquid level gauge is maintained above the freezing point and will not freeze.

[0015] (2) The liquid level meter is attached to the outer wall of the water jacket furnace, which can effectively shorten the length of the connecting pipeline, thereby avoiding freezing and blockage of the liquid in the pipeline due to excessive length of the pipeline.

[0016] (3) After the liquid level meter is installed on the outer wall of the water jacket furnace, the control valve connected to the liquid level meter can be normally opened. The liquid level meter displays the liquid level in the water jacket furnace in real time, which is convenient for staff to observe.

[0017] (4) A magnet is installed on the liquid level gauge so that the liquid level gauge can be firmly adsorbed on the outer wall of the water jacket furnace, so that the heat on the outer wall of the water jacket furnace can be fully transferred to the liquid level gauge, ensuring that there is no ice in the liquid level gauge and keeping the liquid level gauge in normal working condition.

[0018] (5) The liquid level meter can also work normally in the cold and low temperature conditions in winter, which is convenient for observing the liquid level at any time, preventing the water jacket furnace from burning out due to insufficient liquid level in the water jacket furnace. This improves the safety factor and reduces safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
