Drawings
Fig. 1 is a structural sectional view of the valve of the present invention when closed.
Fig. 2 is a structural sectional view of the valve of the present invention when fully opened.
In the figure: the valve comprises a valve body 1, a valve plate 2, a screw rod 3, a ball head 31, a through hole 32, a hollow cavity 4, a hollow cavity hole 41, a groove 42, a sealing element 5 and a gear 6.
Detailed Description
The following describes the implementation of the present invention with reference to the accompanying drawings.
A decompression valve opening structure of a valve comprises a valve body 1, a valve plate 2 and a screw rod 3, wherein the screw rod 3 penetrates through the valve plate 2 through a hole in the middle of the valve plate 2, the bottom of the screw rod 3 is a ball head 31, a through hole 32 is formed in the bottom of the ball head 31 along the axial direction of the screw rod, an outlet of the through hole 32 is formed in the side wall of the screw rod, and when the valve is opened, the outlet of the through hole 32 in the side wall of the screw rod is higher than the upper surface of the valve plate 2. The lower surface of the valve plate 2 is connected with a hollow cavity 4, the side wall of the hollow cavity 4 is provided with a plurality of holes 41, and fluid can flow out of the holes 41 of the hollow cavity and enter the valve body 1 after flowing into the hollow cavity 4 from the through hole 32. The ball head 31 of the screw rod is arranged in the hollow cavity 4, and the bottom of the ball head 31 can be contacted and jointed with the inner surface of the hollow cavity 4.
The hollow cavity 4 and the valve plate 2 are integrally formed or connected through a fastener.
The inner wall of the hole where the valve plate 2 contacts the screw rod 3 is provided with a groove, and a sealing element 5 is embedded into the groove.
The contact surface of the hollow cavity 4 and the bottom of the screw rod ball head 31 is a groove 42 attached to the ball head.
When the valve is opened, the rotating gear 6 drives the screw rod 3 to move upwards, fluid enters the bottom of the ball head 31 from the side wall of the screw rod along the through hole 32 and then enters the hollow cavity 4, then enters the valve body 1 through a plurality of holes 41 in the side wall of the hollow cavity 4, the upper surface of the valve plate 2 is decompressed, the rotating gear 6 continues to be rotated, the ball head is limited by the valve plate, and then the valve plate is driven to move upwards until the valve is completely opened.
When the valve is closed, the rotating gear 6 drives the screw to move downwards, the ball head 31 at the bottom of the screw is in contact with and closely attached to the hollow cavity 4, the gear 6 continues to be rotated, and the screw 3 moves downwards to drive the valve plate to move downwards until the valve is completely closed.
