Abstract
The utility model relates to a zero friction hydraulic ball valve which is a ball valve used for laying a pipeline. Both sides of a ball body, which are limited by a fixed shaft, are provided with two valve seats connected with a valve body in a sliding seal mode. When the valve is opened, the valve seats are separated from ball body media to enter a valve cavity, the media at both sides of a ball tend to balance, and then, the ball body rotates 90 DEG to open the valve. When the valve is closed, the ball body rotates 90 DEG under the state that the valve seats are separated from the ball body, then the valve seats move to the ball body and are used for tightly pressing and sealing, and the condition of opening and closing the valve in zero friction is realized.
Description
Technical field:
The utility model relates to the zero friction hydraulic drive ball valve that uses in a kind of pipe laying.
Background technique:
Advantages such as ball valve is fast with keying speed, the selfsealings tendency is arranged, flow resistance is little, in light weight doubly are popular.Be widely used in the large, medium and small bore of high, medium and low voltage.Be characterized in that sealing surface must keep certain specific pressure to guarantee sealing.This makes the valve opening and closing moment of torsion big, and sealing surface just has wearing and tearing after certain number of times opens and closes, the beginning seepage.Valve is scrapped when leakage rate acquires a certain degree.
Summary of the invention:
The purpose of this utility model provides a kind of zero friction hydraulic drive ball valve, and this valve has overcome that ball valve open and close torque in the past is big, the shortcoming of sealing surface wear seepage, has realized that sealing surface does not have friction and opens and closes, and makes that the ball valve switch is light, the life-span is long.
The technical solution adopted in the utility model is: form this valve by stationary axle 1, spheroid 2, valve seat 3, seal ring 4, valve gap 5, valve body 6, valve rod 7, connecting sleeve 8, swing cylinder 9, U-shaped seal ring 10 and flap 11.Valve gap 5 is fixedlyed connected with valve body 6, and stationary axle 1 is limited to spheroid 2 in the valve body 6 and can only rotates, and valve rod 7 is by flap 11 rotating spheres 2, and spheroid 2 both sides have valve seat 3 and valve body 6 to be slidingly connected, and seal ring 4 is tightly connected with spheroid 2; Flap 11 is tightly connected by U-shaped seal ring 10 and swing cylinder 9, can 90 ° of rotations; Flap 11 is realized 90 ° of rotations of valve by connecting sleeve 8 actuate valve stem 7.
The beneficial effects of the utility model are, have realized that ball valve does not have friction and opens and closes, and have both reduced open and close torque, prolong valve working life again.
Description of drawings:
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is a structure plan view of the present utility model.
Embodiment:
1. valve is from the closed condition to the opening state: valve seat 3 moves and breaks away from spheroid 2, and medium enters body cavity, and 7 turns of flap 11 drive valve rods make spheroid 2 forward the enable possition valve open to then; Valve is from the opening state to the closed condition: flap 11 rotating belt ovable valve stems 7 make spheroid 2 forward closed position to, valve seat 3 is shifted to spheroid 2 then, seal ring 4 and spheroid 2 surface of contact specific pressures rise and reach seal request (its specific pressure can preestablish by adjusting oil pressure), valve closing.
2. the concrete size of valve will be according to different pressures, different size and seal pressure otherwise designed thereof.
3. the seal pressure adjustment realizes by unidirectional pressure regulator valve.
Claims (2)
