Abstract
The utility model discloses a back-water stop valve for a micropore aeration device. The back-water stop valve consists of a rubber sleeve connecting seat (1), a rubber sleeve (2), a valve body (3) and an air tube connecting seat (4), wherein one end of the rubber sleeve connecting seat (1) is inserted into one end of the valve body (3); the rubber sleeve (2) is sleeved on the end part of the rubber sleeve connecting seat (1) in the valve body (3); an air vent (5) is formed in the rubber sleeve (2); the air tube connecting seat (4) is inserted into the other end of the valve body (3); therefore, the whole back-water stop valve is formed. The back-water stop valve has a simple structure, low cost and ideal effects; starting air supply resistance caused by the leakage of water from micropores of a nanotube into an air inlet pipeline in the stopped state of the device is prevented, damage to a motor and the pipeline is avoided, the service life of the motor and the pipeline is prolonged, and maintenance cost is decreased.
Description
Technical field
The utility model relates to stop valve, is specifically related to a kind of backwater stop valve of micro-pore aeration oxygen-increasing device.
Background technique
1,747 ten thousand hectares of China's inland waters gross areas, but 6,750,000 hectares of water surfaces for aquaculture have utilized 5,660,000 hectares; 1,330 ten thousand hectares of 15 meters water depth line shallow seas of growing and intertidal zone beach areas can be supported in more than 1.8 ten thousand kilometer in China shore line, have cultured 132.3 ten thousand hectares.
At present, the main breeding way of China has: freshwater breed, fresh water cultivating large area, fish-farming in shallow marine water, ocean mudflat aquaculture and industrial aquaculture.Existing breeding way major part still is in original extensive cultivation pattern, and output is very low.China is an aquatic products demand and big export country, but wants under limited culture resources, to obtain high yield, stable yields, must change to the intensive culture pattern.
The waters is the living environment of aquiculture animal, and each aquiculture animal all needs the water quality environment that is fit to its existence; Water quality environment is if can meet the demands; Aquiculture animal just can be grown and breed, and pollutes if water quality environment receives certain, and some water quality index exceeds the adaptation of aquiculture animal and restrains oneself scope; The lighter's aquiculture animal can not normal growth, and weight person possibly cause the large quantities of death of aquiculture animal.And fishing pool aerator, feeder are to improve water quality environment to guarantee high yield, the indispensable cultivation equipment of stable yields.Use fishing pool oxygenation function to increase the dissolved oxygen amount in the water, purify water, prevent fish because of anoxic is raised the nose above water to breathe, death, it can effectively improve the fish conditions of existence, improves cultivation density, accelerates fish growth.
Aerator is the effective ways that increase dissolved oxygen content, except increasing oxygen, also can promote the circulation of water, and can prevent the temperature stratification of water body, chemical stratification and oxygen stratification.If aerator running in the depths, pool can improve the soil property of bottom, pool, make underearth oxygenation, and avoid producing toxic gas, prevent the ill death of aquatic livestock.
The micro-pore aeration oxygen-increasing device is to be combined by Roots blower, major-minor pipe, micropore aeration pipe and auxiliary accessories, has characteristics such as energy-efficient, easy for installation, long service life.Its working principle mainly is to utilize advanced nanometer technology, in the nanotube that is distributed near pond bottom, inflates air compression through air compressor, to reach from the bottom effect of the pond being carried out three-dimensional oxygenation.Compare with the conventional surface mechanical enhancement, have oxygenation area evenly, the oxygenation level is balanced, mechanical energy consumption is less, improve advantages such as base ring border effect is obvious.
After the micro-pore aeration oxygen-increasing device is shut down; The pressure that produces along with air on the one hand; Water is penetrated into bronchus at leisure through the tiny hair tracheae of micropore aeration pipe, arrives in the main tracheae through bronchus again, increases the weight of main tracheae weight and makes its submerged; Cause pipeline breaking to damage, slow, the poor phenomenon of oxygenation effect occurs; When starting shooting once more, gas at first slowly is discharged to bronchus from main tracheae with water on the other hand, get rid of from micropore aeration pipe again, during water can produce resistance, motor is caused very big load, even can cause motor to burn out.
Summary of the invention
The purpose of the utility model is: the backwater stop valve that a kind of micro-pore aeration oxygen-increasing device is provided; The backwater stop valve is installed between the bronchus of micro-pore aeration oxygen-increasing device and aeration disk; This backwater stop valve adopts mouse cage type structure; Water infiltrates the start that causes the admission line resistance of supplying gas from the fine pore of nanotube when preventing mechanical halted state, avoids motor and pipeline are caused damage.
The technical solution of the utility model is: this backwater stop valve is made up of rubber sleeve connecting base, rubber sleeve, valve body, tracheae connecting base; One end INSERTTYPE of rubber sleeve connecting base is installed on the end of valve body; Be positioned at socket rubber sleeve on the rubber sleeve connecting base end of valve body; Establish ventilation mouth on the rubber sleeve, INSERTTYPE is installed the tracheae connecting base on the other end of valve body, whole formation backwater stop valve.
During installation, the backwater stop valve is installed between the bronchus of micro-pore aeration oxygen-increasing device and aeration disk, bronchus connects on the rubber sleeve connecting base, and aeration disk connects on the tracheae connecting base; During work, gas gets into aeration disk by bronchus through the backwater stop valve; After the micro-pore aeration oxygen-increasing device was shut down, the ventilation mouth on the rubber sleeve of backwater stop valve stoped water to be penetrated into bronchus at leisure through the tiny hair tracheae of micropore aeration pipe, flow in the main tracheae through bronchus again.
The utility model is simple in structure, and is with low cost, satisfactory for result; Water infiltrates the start that causes the admission line resistance of supplying gas from the fine pore of nanotube when preventing mechanical halted state; Avoid motor and pipeline are caused damage, prolonged the working life of motor and pipeline, reduce maintenance cost.
