Description
Affiliated technical field
The utility model relates to fruit and vegetable storage technique field, specifically a kind of the fruit and vegetable storage is carried out the self-regulating control setup of gaseous tension.
Background technology
The air-regulation type storage is at present to the comparatively advanced a kind of mode of fruit and vegetable storage, and this storage method is under the uniform temperature condition, with keep a value up to specification, than normal air the more carbon dioxide and the air ambient of less oxygen are arranged.This environment can suppress the breathing of fruit and vegetable in storage effectively, prolongs the storage period of fruit and vegetable.Yet the most important condition of this air-regulation type storage operation is that good air-tightness must be arranged, if the requirement of air-tightness out of reach certain index just can't form good controlled atmosphere environment.Secondly, should be able to automatically adjust to the gaseous tension that changes in the storehouse.Because in the air-conditioned cold store normal course of operation, because the variation of storehouse temperature and to the factors such as adjustment of storehouse composition of gases within, the capital changes the gaseous tension in the storehouse, in case the inside and outside differential pressure of storage is excessive and when surpassing specified value, not only can cause the storehouse body to destroy, but also can have a strong impact on storage effect.Therefore, for safety and the storage quality that guarantees the air-regulation type storage, the control and regulation device that keeps the inside and outside gaseous tension relative equilibrium in storehouse must be arranged.
At present, most of use is the hydrolock pressure-regulating device in the air-regulation type storage, inserts the water seal gland water surface by sealing water pipe, forms the water seal state, separates the storehouse inner air and outer air, automatically regulating storehouse internal pressure.When the storehouse internal pressure raises and surpass certain value, by the outwards exhaust automatically of water seal face; When the storehouse internal pressure was lower than certain value, extraneous air made gaseous tension maintenance relative equilibrium in the storehouse by the tonifying Qi in the trend storehouse of water seal face.But the subject matter that this hydrolock pressure-regulating device exists is that the operational use time is shorter, and working stability is poor.Because the water amount in the water seal gland is limited, spontaneous evaporation and the excessive loss of the water yield in control process in addition, these factors all are easy to make the water level in the water seal gland to reduce and adjusting were lost efficacy.Particularly regulate when losing efficacy when the water level in the water seal gland reduces to make, the staff is difficult to again in time find and amount of makeup water at any time.Owing to reliability, the poor stability of control apparatus, consequently will have a strong impact on the normal operation and the storage quality of air-regulation type storage.
Summary of the invention
In order to overcome the problems referred to above that existing hydrolock pressure-regulating device exists, the utility model provides a kind of water seal gland water level that makes relatively stable, and the operational use time is long, the equilibrium of pressure controller of the band automatic water-replenishing device that gas regulation is reliable and stable.
The technical scheme that its technical matters that solves the utility model adopts is: the equilibrium of pressure controller of this band automatic water-replenishing device, the water seal gland that is provided with communicating pipe, sealing water pipe and is arranged on the sealing water pipe bottom, the water seal jacket wall is provided with spillway hole, mainly be to be provided with water supply tank at the top of sealing water pipe and to be provided with filling pipe in the lower end of water supply tank, in water supply tank, be provided with guide rod and be installed in water shutoff plate on the guide rod and the water compensating valve of spring, on water supply tank, be provided with water compensating valve control setup and filler pipe with cover; Said water compensating valve control setup is on the top of water compensating valve guide rod sealed Cellophane to be set and to be provided with briquetting and eccentric wheel successively above sealed Cellophane, and is fixed on the water supply tank by bearing; The lower port of filling pipe is mutually concordant with the sealing water pipe mouth of pipe, and the diameter difference between sealing water pipe and the water seal gland is 3-20mm.
As another kind of improvement the of the present utility model, water compensating valve and water compensating valve control setup can be arranged between sealing water pipe and the water supply tank.
The utility model beneficial effect compared with prior art, mainly be to have set up automatic water-replenishing device on the top of sealing water pipe, thereby can be at any time according to the timely moisturizing of the variation of water level in the water seal gland, guarantee to form between sealing water pipe and the water seal gland normal water level of water seal face, overcome in the past pressure equaliser owing to the operational use time that does not have the automatic water-replenishing device to exist is short, problems such as poor work stability.

The specific embodiment
As shown in Figure 1, the equilibrium of pressure controller of this band automatic water-replenishing device, the water seal gland 11 that is provided with communicating pipe 12, sealing water pipe 7 and is arranged on sealing water pipe 7 bottoms, water seal gland 11 walls are provided with spillway hole 10; Mainly be to be provided with water supply tank 13 at the top of sealing water pipe 7 and to be provided with filling pipe 8 in the lower end of water supply tank 13, in water supply tank 13, be provided with guide rod 15 and be installed in water shutoff plate 14 on the guide rod 15 and the water compensating valve 16 of spring 4, be provided with water compensating valve control setup 1 and filler pipe on water supply tank 13, filler pipe 6 is provided with plug 5; Said water compensating valve control setup 1 is on the top of the guide rod 15 of water compensating valve 16 arc sealed Cellophane 18 to be set and to be provided with briquetting 3 and eccentric wheel 2 successively above arc sealed Cellophane 18, and is fixed on the water supply tank 13 by bearing 17; The lower port 9 of filling pipe 8 is roughly mutually concordant with the mouth of pipe of sealing water pipe 7, and the diameter difference between sealing water pipe 7 and the water seal gland 11 is 10mm.
In another embodiment of Fig. 2, water compensating valve 16 and water compensating valve control setup 1 are combined into one, and are installed between water supply tank 13 and the filling pipe 8, can reach equally by the purpose of water supply tank 13 to water seal gland 11 automatic water supplements.
Working process of the present utility model is: when enabling the equilibrium of pressure controller of automatic water-replenishing device, at first rotate eccentric wheel, under eccentric effect, by pressure water compensating valve guide rod under briquetting and the arc caulking gum film, water compensating valve is closed water supply tank by the water shutoff plate.Back out the plug on the filler pipe then, in water supply tank, add water by filler pipe.Topped up with water bonnet top cement plug, the revolution eccentric wheel, water compensating valve rises under the effect of spring, and the water shutoff plate is opened, and the water in the water supply tank flows in the water seal gland from filling pipe.Simultaneously the lower port of air self-water replenishing pipe enters in the water supply tank, fills water in the water seal gland gradually and outwards flows out from spillway hole.When the air pressure in the water supply tank and the above water column pressure sum of water seal gland water seal face and ambient pressure balanced each other, the water in the water supply tank stopped downward outflow, and water seal forms.When the water surface in the water seal gland descended, outside air entered water supply tank from filling pipe, and the current in the water supply tank flow out automatically, keep normal water seal face.
