Abstract

The utility model provides a freeze-proof water jacket furnace level gauge belonging to devices mounted on water jacket furnaces. The freeze-proof water jacket furnace level gauge comprises an upper cylinder body and a lower cylinder body, wherein, inner chambers of another ball valve installation tube at the lower part and a water drainage ball valve installation tube at the bottom part of the lower cylinder body are communicated with the inner chamber of a glass tube, a liquid storage tube with a closed lower end is arranged in the glass tube, the upper end of an electrical heating body in the liquid storage tube is connected to a joint, the joint is clamped in the port at the upper end of the liquid storage tube, the upper end of the liquid storage tube is positioned in a gland bush, and a soldering terminal outside the joint is electrically connected with the electrical heating body. After the electrical heating body is electrified, water or heat conducting liquid such as oil and the like injected into the liquid storage tube, coupled with the liquid storage tube, can be used for heating water in the glass tube to prevent water in the glass tube on the level gauge from being frozen in winter, thereby ensuring normal operation of the water jacket furnace. Moreover, the utility model is simple and reasonable in structure, easy to manufacture and low in manufacturing cost.

Description

Antifreeze water jacket furnace liquid level gauge

Technical field

The utility model provides the device on a kind of water jacket furnace, especially a kind of liquid level gauge.

Background technology

In oilfield process, the water-jacket typ heating furnace is called for short water jacket furnace and is usually used in crude oil is heated to slough wherein moisture.Because water jacket furnace is usually located at the field, in northerly winter, the water in the glass tube in the liquid level gauge that connects on the water jacket furnace often freezes, and freezes the glass tube that can rise brokenly, and can cause the water in the water jacket furnace excessive, influences the normal operation of water jacket furnace.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of antifreeze water jacket furnace liquid level gauge is provided, and the water in the glass tube when avoiding winter on the liquid level gauge freezes, and guarantees that water jacket furnace normally moves.

The utility model is to realize like this, antifreeze water jacket furnace liquid level gauge, it has upper shell, the top of upper shell is equipped with gland, there is boss the inside of upper shell, the upper end of glass tube is positioned at the boss inboard, there is filler glass tube outside between filler pressure cap and the boss, there is the filler pressure cap lower end of upper shell, the outside of filler pressure cap has outer pressure cap to be installed in the outside of upper shell, the inner chamber of the ball valve mounting pipe on upper shell top communicates with the upper shell inner chamber of boss top, it also has lower shell, the lower end of glass tube is positioned at lower shell, there is another filler pressure cap the upper end of lower shell, there is another filler glass tube outside below another filler pressure cap, the outside of another filler pressure cap has another outer pressure cap to be installed in the outside of lower shell, another ball valve mounting pipe of lower shell bottom, the water drain ball valve mounting pipe inner chamber of bottom communicates with the glass tube inner chamber, the liquid storage tube that lower end closed is arranged in described glass tube, electric heating body upper end in the liquid storage tube is connected on the joint, joint is stuck in the upper end port of liquid storage tube, the liquid storage tube upper end is positioned at gland, and the joint outside has binding post and electric heating body to be electrically connected.

Adopt the water jacket furnace liquid level gauge of said structure, can in liquid storage tube, inject water or wet goods heat-conducting liquid, after connecting the power supply of electric heating body, through heat-conducting liquid, liquid storage tube the water in the glass tube is heated, water in the glass tube when having avoided winter on the liquid level gauge freezes, and has guaranteed that water jacket furnace normally moves.And simple and reasonable, easy to manufacture, production cost is low

Description of drawings

Fig. 1 is the synoptic diagram of the utility model structure.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and using method.

As shown in drawings, the antifreeze water jacket furnace liquid level gauge of the utility model, it is characterized in that, it has upper shell 4, the top of upper shell is equipped with gland 2, there is boss 3 inside of upper shell, the upper end of glass tube 7 is positioned at the boss inboard, there is filler 5 glass tube outside between filler pressure cap and the boss, there is filler pressure cap 14 lower end of upper shell, the outside of filler pressure cap has outer pressure cap 6 to be installed in the outside of upper shell, the inner chamber of the ball valve mounting pipe 1 on upper shell top communicates with the upper shell inner chamber of boss top, it also has lower shell 10, the lower end of glass tube 7 is positioned at lower shell, there is another filler pressure cap 13 upper end of lower shell, there is another filler 9 glass tube outside below another filler pressure cap, the outside of another filler pressure cap has another outer pressure cap 8 to be installed in the outside of lower shell, another ball valve mounting pipe 12 of lower shell bottom, water drain ball valve mounting pipe 11 inner chambers of bottom communicate with the glass tube inner chamber, it is characterized in that, the liquid storage tube 15 that lower end closed is arranged in described glass tube 7, electric heating body 16 upper ends in the liquid storage tube are connected on the joint 17, joint is stuck in the upper end port of liquid storage tube, the liquid storage tube upper end is positioned at gland, and the joint outside has binding post 18 and electric heating body to be electrically connected.

The conventional electric heating body has multiple, as electrothermal tube, heating wire, polycrystalline electric heating membrane pipe etc., can select for use as required.The security of using for improving can be a low tension about 24W with the transformer step-down with the high-tension electricity on the water jacket furnace, is connected on the binding post by power lead.Liquid storage tube preferably adopts opaque material, and it is dark that color is preferably, in order to avoid influence the observation of liquid level.

During use, ball valve mounting pipe 1, another ball valve mounting pipe 12 are connected with the water jacket of water jacket furnace by ball valve, pipeline respectively, its installation site is identical with existing liquid level gauge.Water drain ball valve mounting pipe 11 is connected with a ball valve, so that when maintenance is with the water emptying in the glass tube.Adopted split-type structural, the replacing of parts when being convenient to keep in repair.Gland 2, outer pressure cap 6, another outer pressure cap 8 are installed on the upper and lower cylindrical shell by screw thread respectively.

In the higher time of temperature such as summer, autumn, the heating arrangement of formations such as electric heat conductor can be removed, change the gland of sealing.
