Abstract
The utility model discloses a pressure-equalizing device. The pressure-equalizing device comprises an intermediate container, an equalizing pipe, a reflux device and a reflux pipe, wherein a vent hole is arranged on and communicated with the upper part of the intermediate container, the equalizing pipe and the reflux pipe are arranged on and communicated with the lower part thereof, the reflux device is arranged on the lower part of the reflux pipe, and the lower part of the equalizing pipe extends into the bottom of a tank body. Compared with the prior art, the pressure-equalizing device has the functions of avoiding danger by preventing pressure in the tank from exceeding a specified value, preventing negative pressure from being formed due to temperature change during downtime and preventing equipment from suffering potential safety hazards and is characterized by reasonable design, simple structure, convenient use, and the like, thereby having good value of popularization and usage.
Description
Technical field
The utility model relates to a kind of pressure equaliser, especially a kind of pressure equaliser that prevents to form in the jar in the synthetic production of Choline Chloride malleation or negative pressure.
Background technology
In the actual production, retort is airtight work, and in the synthetic production process of Choline Chloride, outwards stirring and downtime when forming malleation or negative pressure in the retort, cause potential safety hazard to equipment, and cause danger during variations in temperature.At present, good solution is not also arranged.
The utility model content
Technical assignment of the present utility model is to provide a kind of pressure equaliser at above-mentioned deficiency of the prior art, this a kind of pressure equaliser has and prevents that jar internal pressure from surpassing setting and downtime because of being subjected to variations in temperature formation negative pressure, avoid equipment is caused potential safety hazard, and the characteristics of causing danger.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises intermediate receptacle, balance pipe, reflux and return duct, the top of intermediate receptacle is provided with passage and communicates with it, the bottom is provided with balance pipe and the return duct that is connected, the bottom of described return duct is provided with reflux, and the bottom of described balance pipe extend into the bottom of tank body.
A kind of pressure equaliser of the present utility model is compared with prior art, has following outstanding beneficial effect: prevent that jar internal pressure from surpassing setting and the downtime forms negative pressure because of being subjected to variations in temperature, avoid equipment is caused potential safety hazard, and cause danger, reasonable in design, simple in structure, characteristics such as easy to use.
Description of drawings
Accompanying drawing 1 is a kind of user mode schematic diagram of pressure equaliser;
Description of reference numerals: 1, return duct, 2, reflux, 3, passage, 4, intermediate receptacle, 5, balance pipe, 6, tank body.
The specific embodiment
With reference to explaining below 1 pair of a kind of pressure equaliser work of the present utility model of Figure of description.
A kind of pressure equaliser of the present utility model, its structure comprises intermediate receptacle 4, balance pipe 5, reflux 2 and return duct 1, the top of intermediate receptacle 4 is provided with passage 3 and communicates with it, the bottom is provided with balance pipe 5 and the return duct 1 that is connected, the bottom of described return duct 1 is provided with reflux 2, and the bottom of described balance pipe 5 extend into the bottom of tank body 6.
Pressure in tank body 6 raises, and then jar interior 6 liquid rise along balance pipe 5, if surpass the level pressure value of balance pipe 5, liquid will rise to intermediate receptacle 4 from balance pipe 5, enters reflux 2 through return duct 1 again, guarantees that tank body 6 internal pressures are no more than setting.After synthetic the finishing, send liquid and downtime outside when being subjected to the variation of environment temperature, be easy to generate negative pressure in the tank body 6, if generate negative pressure, air then enters from passage 3, enters in the tank body 6 along balance pipe 5, plays the effect of protection tank body 6.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
