Abstract
The utility model discloses a spring pressurizing tank for mechanical sealing of a reaction kettle, which consists of a cylinder barrel (1), a piston (2), a piston rod (3), a tank barrel (4), an end cover (5), a spring (6) and a position indicating barrel (7); an installation spring (6) and a spring pressing ring (61) are arranged on a piston rod (3) on the outer side of an end cover (5), a pressure taking hole (14) communicated with the upper part of an inner cavity of the reaction kettle is formed in the middle of an end disc (12) of a cylinder barrel (1), and a liquid sealing liquid outlet hole (15) and a liquid sealing liquid return hole (16) communicated with an outer side cavity of a mechanical sealing ring of the reaction kettle are formed in the upper part and the lower part of a tank barrel (4) respectively. When the pressure in the reaction kettle is zero, the sealing liquid in the inner cavity of the tank cylinder (4) still keeps a certain pressure under the action of the thrust of the spring, so that the mechanical seal can normally and safely operate in a certain positive pressure state.
Description
Technical Field
The utility model relates to a pressure boost jar of reation kettle mechanical seal auxiliary system.
Background
The pressure boost jar of mechanical seal auxiliary system is a piston jar device, by a jar body, a piston, the piston rod constitutes, pressure in the reation kettle is introduced into piston front end jar intracavity, because the terminal surface is greater than piston rear end face before the piston, receive the pressure action in the reation kettle to make the pressure in the piston rear end jar intracavity be greater than the pressure in the reation kettle, the pressure boost in piston rear end jar intracavity promptly, set up the mechanical seal ring outside chamber of business turn over liquid union coupling to reation kettle on piston rear end jar chamber, thereby realize that mechanical seal ring outside chamber pressure is greater than inboard chamber pressure, make mechanical seal keep moving under the malleation environment of the inboard seepage of sealing ring from the sealing ring outside.
However, the pressure of some reaction kettles is changed in the production process, when the pressure in the reaction kettle is zero, the liquid in the pressurization tank has no pressure, at this time, if flushing liquid is injected into the inner cavity of the mechanical sealing ring, the pressure of the inner cavity of the sealing ring is greater than the pressure of the outer cavity of the sealing ring, the mechanical sealing is operated in a counter-pressure state, and the mechanical sealing structure designed for positive pressure use is easy to damage and fail, so that the mechanical sealing auxiliary system of the working condition can be flushed by a P54 oil station instead of a pressurization tank system, and the cost of the product is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the not enough improvement of above-mentioned prior art reation kettle pressure boost jar for mechanical seal, when providing a pressureless in the reation kettle, the liquid in the pressure boost jar still keeps there is pressure, makes mechanical seal can keep moving in the malleation environment, improves mechanical seal's life, saves product cost.
The utility model discloses a spring pressurizing tank for mechanical sealing of a reaction kettle, which comprises a cylinder barrel 1, a piston 2, a piston rod 3, a tank barrel 4, an end cover 5, a spring 6 and a position indicating barrel 7;
the cylinder barrel 1 is composed of a cylinder 11 and an end disc 12, the cylinder 11 positioned at the center of the end disc 12 is connected with the end disc 12 integrally, the cylinder barrel 1 is connected with the flange of the port of the tank barrel 4 in a sealing way through the end disc 12, the piston 2 is installed in the cylinder 11 of the cylinder barrel in a sliding sealing way, the spigot of the end cover 5 is fixedly installed on the center hole of the bottom 41 of the tank barrel 4 in a sealing way in a matching way, the piston rod 3 outside the end cover 5 is provided with a spring 6 and a spring pressing ring 61, the position indicating barrel 7 outside the end cover 5 is fixedly connected with a position indicating barrel 7, the cylindrical surface of the position indicating barrel 7 is provided with an observation window, the side of the position indicating barrel is provided with a high-low liquid level indicating line, and the displacement of the piston rod 3, namely the variation of liquid in a pressurization tank is indicated, a liquid sealing outlet hole 15 communicated with the outer side cavity of the mechanical sealing ring of the reaction kettle is formed in the end disc 12 of the cylinder barrel 1 corresponding to the outer side cavity B of the cylinder 11 of the cylinder barrel 1, and a liquid sealing return hole 16 communicated with the outer side cavity of the mechanical sealing ring of the reaction kettle is formed in the barrel bottom 41 of the tank barrel 4.
The utility model discloses the thrust of spring 6 acts on piston 2, piston 2 compresses its back cylinder chamber C, make with piston back cylinder chamber C communicating jar of section of thick bamboo 4 intracavity seal liquid production pressure, when realizing that reation kettle internal pressure is zero, get promptly when pressing hole 14 does not have pressure, the liquid that seals of jar of 4 inner chambers still keeps certain pressure, make reation kettle mechanical seal ring outside chamber keep certain malleation, make reation kettle mechanical seal keep moving under certain malleation state, make mechanical seal normal operating, do not damage, lose efficacy.
