Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of tolerance of plastic products is precisely controlled valve and control
Method.
Background technology
In recent years, the water environmental problems of vast rural area and rural area become the hot issue of society.With town and country two
Gradeization, regional imbalance, urbanization development, then towards the development of urbanization, villages and small towns develop into micropolis in some villages and small towns,
Some villages and small towns develop into the blank of the different cities such as tourist industry, industry, business.The density of population reaches a certain level, environmental carrying capacity
It is saturated, the pollution of environment makes entire environment deteriorate more than the self-purification capacity of ecological environment.
There is country sewage water quality and quantity to change greatly, small scale and dispersion, and the vast rural areas lack corresponding technology
Administrative staff, this just needs the sewage treatment process for being applicable in rural area, this technique to need to adapt to the impact of water quality and quantity,
Easily operated management, it is stable, while the ecological requirements of rural area can be met;To adapt to small towns, rural area, joint household, dividing family
Sewage disposal demand, frequently with a kind of integrated sewage treating apparatus include aeration oxygen supply, air lift lift technique, with fully full
Sufficient rural sewage treatment demand, but only have UPVC ball valves, inside screw stop valve door currently on the market;It is supplied using aerating regulation
Oxygen or air lift lift technique:Scheme one when being used in compounding scheme using plastic elbow and UPVC ball valves, can not precisely adjust gas supply
Amount;Scheme two is used in compounding scheme using plastic elbow and inside screw stop valve door, though air demand more can be precisely adjusted,
It has the following problems:It such as needs additionally to use elbow, interior nipple material, the service life of inside screw stop valve door short, easy
Corrosion, and the cost used is higher.For this purpose, be badly in need of developing in the market a kind of collection elbow, silk inside and outside saving, using it is simple, low at
This multi-functional tolerance in one is precisely controlled Plastic valve product, and blank is applied to fill up.
Invention content
In view of the deficiencies of the prior art and the blank of product technology, it is accurate that the present invention proposes a kind of tolerance of plastic products
Control valve and control method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of tolerance of plastic products is precisely controlled valve, which is characterized in that it includes valve body, control mechanism, spool, annular
Sealing element, compensation pad are connected in sequence;The valve body is equipped with air inlet pipe, escape pipe, the embedded frustum of assembly, curl limit successively
Plate, strip fix communication port and circular hole supporting table, and the valve inner is back taper truncated cone-shaped;The control mechanism is equipped with convex
Play positioning three-jaw, interior buckle, locating part;The global shape of the spool is back taper truncated cone-shaped, and spool is equipped with irregular imploded arcs
Shape face concave station, the sunken inside insertion three-jaw hole that end face is equipped with, bottom is equipped with into air cleft, the irregular concave curved surface concave station
By concave edge in level, it is vertical in concave edge, concave edge, the connection of vertical side seam surround in helix;Concave edge in the helix hangs down certainly
Straight flange has stitched until vertical interior concave edge, starts the vertical height for gradually decreasing helix;It puts in the spool back taper round platform direction
Enter valve inner, is just bonded with valve body back taper round platform inner tight outside spool back taper round platform, spool bottom is placed in valve body
On circular hole supporting table;It holds in sunken inside insertion three-jaw hole on the end face of protrusion positioning three-jaw and spool on the control mechanism
It inserts and forms a fixed connection, interior buckle assembles with valve body and embeds frustum on the control mechanism, lip ring connect and to form fixation
End face connection;The protrusion positioning three-jaw of the control mechanism is embedded in three-jaw by the sunken inside being equipped with spool end and cheats socket joint
The elastic surface pressure effect of the compensation pad of inside afterwards so that valve body, spool phase section fit closely.
By using screw thread, grafting, clamping, socket, build-in, sweat soldering, bonding between the valve body and control mechanism
At least one of be attached.
The air inlet pipe of the valve body, escape pipe caliber are 8mm~50mm;The top of the control mechanism is equipped with rotation and carves
Degree.
Concave edge exists with strip fixation communication port bottom in the top helix of irregular concave curved surface concave station in the spool
When different control mechanism swing, the accurate adjusting control overcurrent inner cavity that enclosed can and be formed.
Locating part on the control mechanism coordinates with valve body upper limit wooden partition body circumferentially rotates model to limit control mechanism
It encloses;The flow channels vertical and intersectant centerline of the flow channels of the air inlet tube cavity and the water outlet tube cavity.
A kind of tolerance of plastic products is precisely controlled the control method of valve, it is characterised in that:
Control linkage principle:By the rotating scale for being precisely controlled control mechanism so that the protrusion positioning on control mechanism
Three-jaw forms a fixed connection with the sunken inside insertion three-jaw hole socket joint on the end face of spool and is rotated with swing together with part, to adjust
The control volume inner cavity that the horizontal line of concave edge and irregular concave curved surface concave station is enclosed in control helix, forms different size
Gas overcurrent volume space, change flow channels accurate adjusting control overcurrent inner cavity, so that air inlet is passed sequentially through in air inlet pipe
Chamber is precisely controlled inner cavity, strip fixation communication port, escape pipe, reaches and is precisely controlled tolerance purpose.
(2) valve is closed:When the rotating scale of control mechanism is 0%, concave edge and upper fixed stream in the valve helix
The control overcurrent inner cavity area of port bottom intersection is 0, and gas can not be by controlling overcurrent inner cavity;
(3) valve opening process:The rotating scale of control mechanism increases to 100% process for 0%, controls overcurrent inner cavity surface
Product gradually increases, and gas is gradually increased by controlling overcurrent inner cavity amount;
(4) valve opening is maximum:When the rotating scale of control mechanism is 100%, control overcurrent inner cavity area is maximum, gas
It is maximum by controlling overcurrent inner cavity amount.
The present invention fundamentally accurately controls tolerance by unique structure innovation and control method, facilitates letter
Single, the air lift for the plastic products for having filled up market is precisely controlled the blank of valve, has very big practical application promotional value.
