Abstract
Water seal multiposition gas flow regulating device. It is arranged in gas admission header pipe and composed of box structure body. Top part of the body is connected to gas admission header pipe. The box is divided into a plurality of water seal chambers, each of which is provided with admitting pipe and rising pipe. Control valve is positioned in the pipeline. Moreover, one gas pipeline connecting outside and serving for exhausting gas is arranged respectively for each water seal chamber. The pipeline bends upwards after leaving water seal chamber and forms a ''U'' with water seal chamber. Then, the pipeline will be bent and extended again. Bottom elevation of bent and extended exhaust pipeline is higher that that of highest water level inside water seal chamber, in order to ensure the actual water seal height is larger than intake pressure. The utility model characterized in that working condition of each water seal chamber can be adjusted during the production based on the actual needs, so as to empty gas or admit the entering into cylinder of gas and prevent inward and outward leakage of inflammable gases such as hydrogen etc. In addition, the utility model is easy to operate.
Description
Technical field
The utility model relates to air regulating device in the pipe network.
Background technique
Change flowing to for the atmosphere gas fluid in the pipeline in the prior art all is mounted valve on pipeline house steward that multichannel communicates or arm, opens or closes by related valve, reaches the purpose that gas and changing flows to, and promptly adjusts gas flow on the branch pipe network.
We know, every valve all is the sealing that is made of valve spool (valve plate), valve seat, valve stem seal letter etc., wherein spool (valve plate) is the key of valve seal with the valve seat bond quality, the cleanliness of the sealing of valve and workmanship, fluid, the chemical property of fluid, valve switch frequency etc. have confidential relation, wherein any situation goes out the sealing that a problem all can be destroyed valve, makes valve produce internal leakage or external leakage.Because valve seal is destroyed, strictly speaking, gas changes the order that flows to and also fails therefrom on pipe network, if gas has dangerous or inflammable and explosive property, may take place fully to cause great serious accident owing to the leakage of valve.Such as in the electrolytic hydrogen production industry, enter pipeline 10a after hydrogen is made and will carry out shunt, gas promptly off quality can not be incorporated pipe network into, necessary emptying, just stop emptying after hydrogen quality is qualified, incorporates pipe network 20a (as shown in Figure 1) into, these operations in the past all are to switch by valve to finish.Because the internal leakage of valve 30a, atmosphere can enter pipe network by exhausting pipeline 40a, the hydrogen oxygen content is risen, if oxygen content is too high, serious threat is to the safe operation of hydrogen gas compressor and hydrogen purification device, once took place because the hydrogen oxygen content rises, the catalyst reaction temperatures that causes hydrogen purification device is high and lost efficacy.
Summary of the invention
The purpose of this utility model is to provide a kind of water-sealed type multidigit gas flow controlling device, is applied in the pipe network of atmosphere gas, can stop the problem of the leakage that valve brings, and guarantees that gas safety changes to flow to and the relevant device safe operation.
For achieving the above object, the technical solution of the utility model is, water-sealed type multidigit gas flow controlling device is installed among the gas intake manifold, comprise, and body, it is with housing structure, its top is communicated in the gas intake manifold; Divide in the casing to be separated with some water tight compartments, each water tight compartment is provided with intake pipe and outlet pipe, is provided with control valve in the pipeline; Each water tight compartment also respectively is provided with the gas pipeline that leads to the external world, is used for exhaust, pipeline is upwards bent after going out water tight compartment, form " U " font with water tight compartment, and then bending is extended, exhaust duct bottom absolute altitude after bending is extended again is higher than the absolute altitude of the highest water level in the water tight compartment, the highest water level of water tight compartment and the extreme lower position of water-sealing discharge pipe are poor, guarantee that actual water seal height is greater than suction pressure.
Further, water tight compartment also is communicated with and is provided with a level meter, so that control water seal liquid level.
Advantage of the present utility model is, can regulate the working condition of each water tight compartment aborning as required, to reach the purpose that emptying or gas advance cylinder, prevents the inside and outside leakage of inflammable gases such as hydrogen, and, simple to operate.

Embodiment
Referring to Fig. 2～Fig. 4, water-sealed type multidigit gas flow controlling device of the present utility model is installed among the gas intake manifold 2, comprises body 1, and it is with housing structure, and its top is communicated in gas intake manifold 2; Divide in the casing 10 to be separated with some water tight compartments 100,200, each water tight compartment 100,200 is provided with intake pipe 4 and outlet pipe 5, is provided with control valve 6,7 in the pipeline; Each water tight compartment 100,200 also respectively is provided with the gas pipeline 8 that leads to the external world, is used for exhaust, it is upwards curved that pipeline goes out water tight compartment 100,200 backs, form " U " font with water tight compartment 100,200, and then bending is extended, exhaust duct bottom 81 absolute altitudes after bending is extended again are higher than the absolute altitude of the highest water level in the water tight compartment 100, i.e. " U " font final vacuum pipeline is minimum walks the absolute altitude that flat absolute altitude is higher than the highest water level in the water tight compartment, the highest water level of water tight compartment and the extreme lower position of water-sealing discharge pipe are poor, and promptly actual water seal height is greater than suction pressure; Water tight compartment 100,200 also is communicated with and is provided with a level meter 9, so that control water seal liquid level.
The needs water tight compartment of ordering according to user in the pipe network is divided into n water tight compartment, and is provided with and is used for the gas pipeline of exhaust.
To divide water seal to be arranged in order and be 1#, 2#, 3# ... n#, if air-flow will divide water seal to walk from certain, water in this minute water seal is all drained, all the other branch water seals all add water and carry out water seal, make the water seal water level be higher than gas pressure, gas just enters the branch water seal of sky water level like this, and then enters the exhaust duct of this minute water seal, reaches the purpose that changes gas flow.Allow certain divide water seal to become the envelope gaseity by original exhaust condition, can open the inlet valve of this minute water seal, close its drain valve, the water level of whole like this minute water seal just begins to rise, and when the water seal water level surpassed gas pressure, this minute water seal just stopped exhaust.And then close inlet valve.Allow certain divide water seal to become exhaust condition by original envelope gaseity, can open the drain valve of this minute water seal, close its inlet valve, the water level of whole like this minute water seal just begins to discharge, and till draining, this minute water seal just becomes unimpeded gas circuit like this.
The utility model is applied to the pipe network of the water electrolysis hydrogen producing in the hydrogen-oxygen station, pass through the utility model, hydrogen and oxygen that electrolytic bath is made are divided into into cylinder storage, the water seal of envelope cylinder state (diffusing) five equilibrium respectively, regulate the working condition of each water seal aborning as required, to reach the purpose that emptying or gas advance cylinder, after this device uses, the inside and outside leakage of hydrogen did not take place thoroughly eliminated the hydrogen gas leakage unsafe factor that valve causes thus.
