Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in figs 1 to 6, the present invention provides a kind of throttles the technology of agricultural valve with pressure control waterstop antiseepage
Scheme:
As shown in Figure 1-Figure 3, a kind of to throttle agricultural valve with the antiseepage of pressure control waterstop, structure include handwheel 1,
Driver 2, antiseepage throttling set 3, mounting flange 4, the handwheel 1 and driver 2 are sequentially connected, the antiseepage throttling
Device 3 is connected with mounting flange 4, and the driver 2 and antiseepage throttling set 3 are mechanically connected, the antiseepage throttling
Device 3 includes catch bar 31, antiseepage throttling valve core 32, connection frame 33, atmospheric pressure cavity 34, gas-guide tube 35, closed percolator 36, leads
Water hole 37, thimble 38, the catch bar 31 are welded with 32 phase of antiseepage throttling valve core, and the lower section of the connection frame 33 is equipped with gas
Chamber 34 is pressed, the gas-guide tube 35 is connected with closed percolator 36, and the lower section of the water-guiding hole 37 is equipped with thimble 38.
As shown in figure 4, the antiseepage throttling valve core 32 includes spool main body 3201, sliding shoe 3202, closed antiseepage block
3203, locating piece 3204, elastic element 3205, the spool main body 3201 is interior to be equipped with sliding shoe 3202, the sliding shoe
3202 weld with closed 3203 phase of antiseepage block, and the locating piece 3204 and elastic element 3205 are mechanically connected, and pass through thimble 38
Push the closed antiseepage block 3203 mobile, so that closed antiseepage block 3203 matches the company with card slot and key with waterstop 3603
The mode of connecing is fixed, and the airtightness of device is improved.
As shown in figure 5, the closed percolator 36 includes air guide connector 3601, air bag 3602, waterstop 3603,
The air guide connector 3601 is connected with air bag 3602, and the air bag 3602 and waterstop 3603 are mechanically connected, and passes through
Connection frame 33 squeezes the air in atmospheric pressure cavity 34, and the air pressure of generation pushes waterstop 3603 and closed antiseepage by air bag 3602
The even closer fitting of block 3203.
As shown in Fig. 2-Fig. 3, the top of the thimble 38 is circular configuration and a diameter of 3cm, is tied by its circle
Structure reduces the friction between thimble 38 and sliding shoe 3202.
As shown in fig. 6, the waterstop 3603 is back-shaped structure, the inside groove of the waterstop 3603 and closed antiseepage
Block 3203 is mutually matched, thus even if antiseepage throttling valve core 32 is worn, but closed antiseepage block 3203 is appointed with waterstop 3603
So it can be closely adhered to.
It is as follows that it implements principle: when valve to be closed, catch bar 31 being driven to push antiseepage by rotation hand wheel 1
Throttling valve core 32 moves down, and connection frame 33 also moves while antiseepage throttling valve core 32 moves down, thus connection frame
33 squeeze the air in atmospheric pressure cavity 34, then are imported air pressure in closed percolator 36 by gas-guide tube 35, thus air bag 3602
It expands against waterstop 3603 to be displaced outwardly, while antiseepage throttling valve core 32 is moved down and is in contact with thimble 38, thimble 38 pushes away
Dynamic sliding shoe 3202 is displaced outwardly, so that sliding shoe 3202 drives closed antiseepage block 3203 to be displaced outwardly, and then closed antiseepage block
In 3203 insertion waterstops 3603, is fixed by the connection type of card slot and key, strengthen waterstop 3603 and closed antiseepage block
3203 stable connection performance, thus even if antiseepage throttling valve core 32 is worn, but closed antiseepage block 3203 and waterstop
3603 so can be closely adhered to, to improve the antiseepage restriction effect of valve.
Problems solved by the invention be the prior art valve when used for a long time, since the multiple switch of valve is so that valve
Core and valve pocket phase mutual friction, cause valve that can not form complete sealing, and water flow infiltration occur causes excessively to irrigate and crops
Drowned phenomenon, the present invention are combined with each other by above-mentioned component, and relatively in traditional valve, the present invention throttles in antiseepage
Under the action of spool and closed percolator, the airtightness of valve is preferably improved, to play the effect of antiseepage throttling, is passed through
The movement of closed antiseepage block and the back-shaped structure of waterstop are fixed to realize by the connection type of card slot and key, and sealing is strengthened
The stable connection performance of band and closed antiseepage block, thus even if spool is worn, but closed antiseepage block and waterstop Ren Ranke
It to improve the antiseepage restriction effect of valve, and is circular configuration and sliding shoe lower end by the top of thimble to fit closely
Semi arch structure, to reduce the friction of thimble and sliding shoe.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention, for this field skill
For art personnel, it is clear that invention is not limited to the details of the above exemplary embodiments, and without departing substantially from spirit of the invention or
