Direct burial stop valve is installed and operation principle：
In engineer applied, stop valve of the present invention is installed on field and fixes furrow ridge position, the top pilferproof closure of screw rod casing 2
1, slightly above in furrow ridge top surface, is advisable in order to open and close.Because the boundary ridge that the furrow ridge is generally two peasant households point ground is fixed in field, generally protect
Stay motionless, do not influence farm machinery tillage.
During normal operation, stop valve is in opening, and locks pilferproof closure 1 for non-irrigation season and irrigation；Irrigate
Season, when pipeline appearance damage needs cut off the water maintenance, opens pilferproof closure 1, with spanner rotation keying screw rod 2 is opened and closed, is driving spiral shell
Under female 21 effect, open and close screw rod 3 and move downward, drive combination water check valve 4 operation downwards to the valve plate seat 17 of the bottom of valve plate room 16,
The limbers 13 of the bottom of valve plate room 16 is closed and current are blocked, so as to carry out tubular service；After the completion of tubular service, with opening
Close spanner to rotate counterclockwise, keying screw rod 3 is moved upwards, while opening sealing valve plate, now combine water check valve bottom water flowing
Hole 35 is opened, and water flows through limbers between support, the limbers 29 of the side of valve body 28 and bottom limbers 35 and valve plate room 16
The limbers 13 of bottom flows into downstream line；With the circulation of current, manifold pressure reduces, at the same with open and close screw rod 3 after
It is continuous to rise, drive combination water check valve 4 to rise and make the fully open and normal water flowing in 16 bottom limbers of valve plate room 13, finally lock
The pilferproof closure 1 at the top of screw rod casing 2.
Combination water check valve 4 is fully open by the bottom limbers 13 of valve plate room 16 at twice, and its major function is exactly that reduction is opened
Qi Li, reduces and is damaged opening and closing screw rod 3 and the grade part of drive nut 21 etc. because opening force is excessive, and this function is in larger caliber etc.
It is particularly important on field pipeline irrigation system shut-off valve.
