Description
Technical field
The utility model belongs to groundwater monitoring technical field, more particularly to a kind of sealing dress of artesian well monitoring well head
It sets.
Background technology
Can be diving and artesian water by underground moisture according to burial types, artesian water hydrostatic pressure is above the ground level, in drilling well
It is drilled into artesian aquifer, artesian water can gush out earth's surface in drilling, artesian well be formed, in groundwater monitoring engineering, because of underground water
Gravity flow and the higher problem of water pressure are difficult to seal artesian well first, it is difficult to install long-term automated monitor and carry out water sample
Acquisition；Secondly, underground water, which flows automatically, can cause the waste of great lot of water resources, and generate certain destroy to earth's surface.Therefore, in artesian well
When being drilled to, often take to increase well head and backfill shut-in well two ways being handled, the former causes the long term monitoring of underground water
Great difficulty, the latter then waste a large amount of fund.
Invention content
The invention aims to solve the problems, such as appeared in above-mentioned existing background technology, and provide a kind of artesian well prison
Log well the sealing device of mouth, the utility model can overcome artesian pressure, effectively control artesian well gravity flow, automatic water seal ventilation with
Pit shaft inner and outer air pressure is balanced, the requirements such as long term monitoring, water sampling, borehole cleaning well-flushing are met, is suitable for a variety of well casing materials, this reality
With new structure it is succinct, it is multiple functional, be easily installed, realize the long term monitoring of artesian well in groundwater monitoring engineering.
A kind of sealing device of artesian well monitoring well head, is made of, upper flange plate includes upper flange plate and lower flange
First disk body, water intake valve, intelligent pressure control valve and giving young employees remedial-courses in general knowledge and vocational skills core seal nipple have water sampling pipe, lower flange on water intake valve
Disk is fixed at well casing upper end, and upper flange plate, which is bolted, to be arranged on lower flange, upper flange plate and lower flange
Between there is rubber pad, seal upper flange plate and lower flange, water intake valve, intelligent pressure control valve and be bolted set respectively
It sets on the first disk body, giving young employees remedial-courses in general knowledge and vocational skills core seal nipple is embedded on the first disk body, and monitoring in well is equipped on giving young employees remedial-courses in general knowledge and vocational skills core seal nipple
Instrument.
The operation principle and process of the present invention：
According to upper flange plate that the characteristics of artesian well and the requirement of groundwater monitoring, the utility model includes, lower flange
With rubber pad for realizing the hermetic seal of gravity flow well head, when needing well-flushing, upper flange plate can be dismantled, tripping in pump carries out well-flushing
Operation；Intelligent pressure control valve can be ventilated with sealing, the air pressure inside and outside balanced well mouth；Giving young employees remedial-courses in general knowledge and vocational skills core seal nipple is transferred for installing
The monitoring instruments such as water level, temperature in well；Water intake valve and water sampling pipe are used to acquire the water sample in artesian well.
Beneficial effects of the present invention：
The utility model can overcome artesian pressure, effectively control artesian well gravity flow, and automatic water seal is ventilated to balance pit shaft
Inner and outer air pressure, meets the requirements such as long term monitoring, water sampling, borehole cleaning well-flushing, and the utility model is simple for structure, multiple functional, easy
In installation, the long term monitoring of artesian well in groundwater monitoring engineering is realized, can effectively control artesian well gravity flow, it can be achieved that certainly
The automatic water seal ventilation for flowing monitoring well, meets the requirements such as hydrologic monitoring, water sampling, borehole cleaning well-flushing, is suitable for a variety of well casing materials
Material, for long-term artesian well and seasonal artesian well monitoring works.

On lower flange 2, there is rubber pad 4 between upper flange plate 1 and lower flange 2, seals upper flange plate 1 and lower flange 2, take
Water valve 12, intelligent pressure control valve 13 are bolted respectively to be arranged on the first disk body 11, and giving young employees remedial-courses in general knowledge and vocational skills core seal nipple 14 is inlayed
On the first disk body 11, monitoring instrument 5 in well are installed on giving young employees remedial-courses in general knowledge and vocational skills core seal nipple 14.
The operation principle and process of the present invention：
According to the characteristics of artesian well and the requirement of groundwater monitoring, upper flange plate 1, the lower flange that the utility model includes
2 and rubber pad 4 for realizing gravity flow well head hermetic seal, when needing well-flushing, upper flange plate 1 can be dismantled, tripping in pump carry out
Clean-out service；Intelligent pressure control valve 13 can be ventilated with sealing, the air pressure inside and outside balanced well mouth；Giving young employees remedial-courses in general knowledge and vocational skills core seal nipple 14 is used for
The monitoring instruments such as water level, temperature in installation decentralization well；Water intake valve 12 and water sampling pipe 121 are used to acquire the water in artesian well
Sample.
