Description

Technical Field

[0001] The utility model relates to the field of regulating valves, in particular to a steam regulating valve for an esterification reaction kettle used in the production of butyl acetate. Background Art

[0002] Butyl acetate is a colorless, transparent liquid with a pleasant fruity odor. Lower homologues are insoluble in water, miscible with organic solvents such as alcohol, ether, and ketone, flammable, and have low acute toxicity, but are highly irritating to the eyes and nose, and can cause anesthesia at high concentrations. At present, the production of butyl acetate requires the use of a reactor to esterify the raw materials used in the production of butyl acetate. For some reactors with temperature requirements, they are generally equipped with jackets, and circulating heat transfer oil or high-temperature steam is introduced into the jacket to achieve heating of the reactor. In particular, for high-temperature steam as a heat source, a valve is used to control the intake of high-temperature steam to achieve temperature regulation, but this type of valve has high requirements for high temperature resistance.

[0003] The comparative patent with publication number CN209856393U aims at the poor high temperature resistance of the existing regulating valve. The design of the polytetrafluoroethylene sealing ring not only has the sealing function, but also has the characteristics of high temperature resistance. In addition, the filler is a flexible graphite filler. Since flexible graphite has extremely strong temperature resistance, it can be used in the range of less than 1000℃, and the temperature of saturated steam is generally less than or equal to 180℃, so that the regulating valve can achieve the purpose and performance of high temperature resistance; in addition, the guide sleeve can guide the movement of the valve stem, so that the valve core and the valve seat can maintain a good and precise match, so as to improve the reliability of the use of this regulating valve.

[0004] However, the temperature-resistant sealing ring of the regulating valve in the above-mentioned comparative patent will age due to long-term exposure to high temperature, the bonding force between the rubber components will weaken, the original performance will be lost, the rubber will become brittle, the toughness will decrease, and it will be easy to crack or deform, and the rubber sealing ring needs to be replaced regularly. However, the existing regulating valve is connected and fixed to the connecting pipe by multiple bolts at both ends, and at least two workers are required during the docking process. One worker always keeps the regulating valve disc and the docking pipe lifted and aligned, and the other worker engages the bolts and installs them in the aligned screw holes. The installation efficiency is low, which brings inconvenience to the disassembly and assembly of the regulating valve and the replacement of the sealing ring. At the same time, the existing valve body needs to transport high-temperature steam, and the internal accessories will age under long-term high temperature. The exterior of the existing regulating valve body is an integrated cast structure, which is not convenient for external cooling equipment and cannot provide effective cooling treatment, thereby reducing the service life of the regulating valve.
