Description

an asphalt valve

【Technical field】

The utility model relates to the field of carbon production, in particular to an asphalt valve used in the production of carbon products.

【Background technique】

As is known, asphalt is used in the production process of carbon products, so it is necessary to use corresponding pipelines to transport asphalt. In order to avoid the condensation of asphalt when passing through the valve in the pipeline, the phenomenon of clogging the valve core will occur and affect the normal operation. Operation, the traditional asphalt valve body is equipped with a spirally wound electric heating wire 8, which uses the heat of the electric heating wire to heat the asphalt valve, so as to achieve the purpose of ensuring that the asphalt in the valve will not condense, see Figure 1; however, In long-term practical application, it is found that the heating temperature of the heating wire is not very uniform, that is, the temperature of the part of the asphalt valve body that directly contacts the heating wire is higher than the temperature of the part that does not directly contact the heating wire, and once a certain part of the asphalt valve body If the temperature of the asphalt valve remains high, it will cause the asphalt inside the part to coke due to the high temperature, which will also cause blockage; in addition, because the heating wire needs to be removed when the asphalt valve is overhauled, otherwise the overhaul cannot be carried out, and The entangled heating wire is prone to breakage during the dismantling process, which results in higher repair and maintenance costs for the user.

【Content of invention】

In order to overcome the deficiencies in the background technology, the utility model discloses an asphalt valve. The asphalt valve can not only effectively prevent the valve core from being blocked, but also facilitate maintenance.

In order to realize the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

An asphalt valve, the asphalt valve includes an asphalt valve body and a heating jacket; the outer part of the asphalt valve body is provided with a corresponding heating jacket, and the upper and lower ends of the heating jacket are respectively fixed to the asphalt valve by bolts. The upper and lower ends of the body are connected by flanges. The heating jacket is provided with an interlayer for the circulation of the heat transfer medium, and the bottom of one side of the heating jacket is provided with the inlet of the heat transfer medium, and the top of the other side is provided with the outlet of the heat transfer medium.

Further, the upper and lower ends of the heating jacket are respectively fixed with bolts opposite to the screw holes of the corresponding flanges.

Further, the shape of the heating mantle is round or square.

Further, the heating jacket is formed by splicing two symmetrical half jackets correspondingly, and each half jacket is provided with an interlayer and an inlet and an outlet of a heat-conducting medium.

Due to the adoption of the above-mentioned technical scheme, the utility model has the following beneficial effects:

The asphalt valve described in the utility model has a simple structure and is easy to disassemble; the asphalt valve is heated evenly and the temperature is easy to control, which can not only effectively meet the heating requirements of the valve body, but also effectively avoid the asphalt in the valve during work. Coking and plugging of the valve core occur; at the same time, since the asphalt valve is equipped with a heating jacket that is easy to install and disassemble and can be used repeatedly, it can be easily repaired and maintained; Based on this, and many comparative experiments have proved that, compared with the electric heating wire heating method of the traditional asphalt valve, the heating jacket heating method adopted by the asphalt valve is not only safer during heating, but also consumes less energy during heating. Smaller, it can save about 100 degrees of electricity per day on average, which can effectively increase economic benefits for the user.

【detailed description】

The present invention can be explained in more detail by the following examples, and the purpose of disclosing the utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:

With reference to the asphalt valve described in accompanying drawing 2, the described asphalt valve includes the asphalt valve body 1 and the heating jacket 2; shape structure, the shape of the heating jacket 2 can be set to a circular or square shape suitable for it, so as to achieve the purpose of making the asphalt valve more beautiful as a whole; It is connected with the flange 4 fixed on the upper and lower ends of the asphalt valve body 1, so as to facilitate the corresponding installation and disassembly operations by tightening the bolts 3; as required, the end faces of the upper and lower ends of the heating jacket 2 can be fixedly arranged and connected with the end face respectively. The bolt 3 corresponding to the screw hole of the flange 4 can position the heating jacket 2 through the corresponding cooperation between the bolt 3 of the heating jacket 2 and the corresponding screw hole on the flange 4;

In order to implement heating, the heating jacket 2 is provided with an interlayer 5 for heat conduction medium, such as hot kerosene and other heat mediums to flow and circulate, and the bottom of one side of the heating jacket 2 is provided with an inlet 6 of a heat conduction medium, and the other side of the heating jacket 2 The outlet 7 of the heat-conducting medium is provided at the top of the side, that is, when the heat-conducting medium flows through the interlayer 5 of the heating jacket 2, it can conduct its heat to the asphalt valve body 1. Since there is an interval between the two, the heat conducted can be uniform. The asphalt valve body 1 is heated; according to the needs, the heating jacket 2 can be spliced by corresponding two symmetrical half sets, and each half set is provided with an interlayer 5 and an inlet 6 and an outlet 7 of a heat-conducting medium. Therefore, the purpose of more convenient installation and disassembly can be achieved by utilizing two spliced half sets.

When implementing the asphalt valve described in the utility model, it is only necessary to connect the inlet 6 and the outlet 7 of the heating jacket 2 with the pipeline of the corresponding heat-conducting medium before use, and first pass the heat-conducting valve into the interlayer 5 of the heating jacket 2. Medium, so that the heat transfer medium circulates in the interlayer 5 of the heating jacket 2, and then the asphalt valve can be used.

The unspecified part of the utility model is the prior art, so the utility model does not describe it in detail.
