Abstract
The utility model relates to an automatic pressure relief device of a pressure container, which can perform pressure relief automatically when certain positive pressure and negative pressure occurring on an industrial storage tank under the condition that working personnel cannot monitor the positive pressure and the negative pressure. The automatic pressure relief device consists of a tank body, an air inlet pipe, an air outlet pipe and a water charging pipe, wherein the air inlet pipe, the air outlet pipe and the water charging pipe are arranged at the top of the tank body in sequence; the air inlet pipe is connected with the top of the pressure container which is used; an air inlet valve is arranged on the air inlet pipe; a water charging valve is arranged on the water charging pipe; a liquid discharge valve is arranged at the main part of the tank body; and an installation position of the liquid discharge valve is arranged at the lower part of the tank body. The automatic pressure relief device is simple in structure and is convenient to use; when the pressure occurring in the used pressure container is beyond the required pressure, the automatic pressure relief device can quickly relieve the pressure so as to ensure the equipment to operate safely.
Description
Technical field:
The utility model relates to storage tank that industry go up to use when occurring certain malleation with negative pressure, the personnel control less than situation under a kind of automatic pressure-relieving device of ability automatic pressure-relieving.
Background technique:
Pressurized container: generally make a general reference and in commercial production, be used to accomplish production processes such as reaction, mass transfer, heat transfer, separation and storage, and can bear the seal container of pressure loading (internal force, external force).It is the equipment that each department in national economy such as petrochemical industry, energy industry, scientific research and military projects all plays an important role.Gas or fluid pressure are born in inside or outside, and the seal container that Security is had higher requirements.The service condition of pressurized container is relatively harsher.Pressurized container is not only bearing the pressure loading that varies in size (in the ordinary course of things still pulsating load) and other load, and what have still is under the condition of high temperature or deep cooling, to move, and working medium often has corrosivity again, and work condition environment is more abominable.At present, the various pressurized containers, the storage tank that use in the industry are very many, when normal production and stopping production, certain pressure surge can often occur.When emptying was stopped up, when the malleation of appearance and negative pressure exceeded the malleation that equipment bears or the negative pressure limit, personnel did not monitor and will cause danger, and understand the damage of build-up of pressure container like this, even cause staff's injury.The pressure facility internal pressure of each enterprise is monitored by personnel fully now, but the variation of pressure is uncertain, if the staff neglects or lacks a sense of responsibility, will cause to have a strong impact on, and has influence on enterprise security property.
The model utility content:
For addressing the above problem, the utility model provides a kind of automatic pressure-relieving device, and this apparatus structure is simple, and is easy to use, when the pressure of the pressurized container appearance of using surpasses authorized pressure, can lay down rapidly, guarantees the safe operation of equipment.
The technological scheme that the utility model adopts is:
The automatic pressure-relieving device is made up of suction tude, filler pipe and steam outlet pipe that tank body and tank body top set gradually; One end of suction tude links to each other with the pressurized container top of use; The other end is deep into the bottom of tank body; Suction tude is provided with suction valve, and filler pipe is provided with priming valve, is provided with liquid discharging valve at the can body of tank body.
Further, the mounting point of described liquid discharging valve according to the positive negative pressure value during predetermined release confirm.
The variation in pressure of the beneficial effect of the utility model for adopting the automatic pressure-relieving device to come the monitor force container:
1, the suction tude of automatic pressure-relieving device links to each other with the pressurized container top of use; When the pressure in the pressurized container exceeds predetermined positive pressure; Liquid in the automatic pressure-relieving device is extruded from steam outlet pipe; Liquid surface is understood great amount of bubbles then, and the gas that ejects is got rid of through steam outlet pipe, makes pressurized container recover normal pressure.
2, when the pressure in the pressurized container exceeds predetermined negative pressure, the interior liquid of automatic pressure-relieving device is inhaled in the pressurized container from the suction tude of automatic pressure-relieving device, gas gets into tank body from steam outlet pipe.Recover just often Deng container inner pressure, great amount of bubbles appears in the liquid level in the tank body.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Specific embodiments:
Below in conjunction with Fig. 1 the utility model is done further to specify.
Shown in Fig. 1, the automatic pressure-relieving device is made up of suction tude 2, filler pipe 4 and steam outlet pipe 6 that tank body 1 and tank body 1 top set gradually, have in the tank body 1 certain water level, water level be according to positive negative pressure value during predetermined release and definite; One end of suction tude 2 links to each other with the pressurized container top of use, and the other end is deep into the bottom of tank body 1, and suction tude 2 is provided with suction valve 3, and filler pipe 4 is provided with priming valve 5, and steam outlet pipe 6 is provided with gas outlet valve 7; Be provided with liquid discharging valve 8 in the bottom of tank body 1, have the height of certain water level consistent in the mounting point of liquid discharging valve 8 and the tank body 1.
The automatic pressure-relieving device of the utility model is at first closed suction valve 3, liquid discharging valve 8 in when operation, opens priming valve 5, in tank body 1, adds water from filler pipe 4, the liquid level of water according to the positive negative pressure value during predetermined release confirm.Close priming valve 5 then; Keep suction tude 2 to link to each other with the pressurized container top of using, suction valve 3, gas outlet valve 7 are held open state at this moment, liquid discharging valve 8 state that keeps shut.When vessel internal pressure power exceeds predetermined positive pressure, the liquid in the automatic pressure-relieving device is extruded from steam outlet pipe 6, can emit vapour in a large number then, make the pressure recovery in the pressurized container normal.When vessel internal pressure power exceeds predetermined release during negative pressure value, the liquid in the automatic pressure-relieving device is inhaled in the pressurized container from the suction tude 2 of automatic pressure-relieving device, after negative pressure was unsnatched, it is normal that pressurized container recovers, and steam outlet pipe 6 can emit vapour in a large number.
When using the automatic pressure-relieving device, to check whether the amount of liquid in this device is in normal liquid level every day.Inspection method is: close the suction valve 3 on the suction tude 2 of automatic pressure-relieving device, open liquid discharging valve 8 then, if there is liquid to flow out, let its flow to do not flow out till; If there is not water to flow out, close suction valve 3, open priming valve 5 and add water, be added to till the liquid outflow.Behind the EO, close priming valve 5, liquid discharging valve 8, open the suction valve 3 on the suction tude 2 of automatic pressure-relieving device, the normal use.
Be noted that at last; The above embodiment is to the explanation of the utility model technological scheme and unrestricted; Other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to existing technology; As long as do not exceed the thinking and the scope of the utility model technological scheme, all should be included within the desired interest field of the utility model.
