Description
Technical field
The present invention relates to a kind of hydrovalve, particularly a kind of heavy caliber hydrovalve
Background technique
Current generally the valve of Shi Yonging is a hydraulic sluice valve in chemical fertilizer coal gas industry, in the gas making of fixed bed intermittent type, frequent opening/shutting valve, and along with the continuous expansion of coal gas burner hearth, gas production is also increasing, just needs large bore valves to satisfy the demand of production technology.But, present general hydrovalve, ratio of height to diameter is generally about 6 times.The valve of Φ 500 has had more than 3 meters high, can only indulge and put, can't traverse, bring restriction to use.
Summary of the invention
For overcoming above-mentioned defective, the object of the present invention is to provide the fast hydraulic fast-oscillating valve of a kind of swing speed simple in structure.
For achieving the goal, hydraulic fast-oscillating valve of the present invention comprises tubular valve body, passes the rotating rotating shaft that is provided with the valve body hermetic seal of valve body in a side of valve body, and the axis of described valve body and the axis of rotating shaft are perpendicular; The two ends of rotating shaft are stretched out outside the valve body and the power arm that is connected with oil hydraulic cylinder are installed; Be fixed with crank in the rotating shaft in valve body, the other end end at crank is provided with connecting rod, the other end of connecting rod is equipped with a circular valve plate, is provided with the valve seat suitable with circular valve plate towards valve plate in the valve body entrance point, and the space of enough circular valve plates along the rotating shaft rotation arranged in the described valve body; When described power arm rotated, the crank that drives in rotating shaft and the rotating shaft rotated, thereby makes circular valve plate rotate in valve body along rotating shaft, when valve plate turns to the valve seat position, valve is in closed condition, and during other position in valve plate turns to valve body, valve in opened condition.
Adopt the present invention of said structure, utilize lever principle, make the rotation of crank, connecting rod, swing produce speed difference and pressure difference, thereby realize quick deflection, the swing of valve, realize that low-power produces big pressure, low energy consumption produces high-speed, reaches high production low energy consumption.
Description of drawings
Fig. 1 is the structural representation of hydraulic fast-oscillating valve of the present invention.
Embodiment
As shown in Figure 1, hydraulic fast-oscillating valve of the present invention comprises tubular valve body 1, passes the rotating rotating shaft 9 that is provided with the valve body hermetic seal of valve body 1 in a side of valve body 1, and the axis of the axis of described valve body 1 and rotating shaft 9 is perpendicular; The two ends of rotating shaft 9 are stretched out outside the valve body 1 and the power arm 7 that is connected with oil hydraulic cylinder 8 are installed; Be fixed with crank 5 in the rotating shaft 9 in valve body 1, the other end end at crank 5 is provided with connecting rod 4, the other end of connecting rod 4 is equipped with a circular valve plate 3, in valve body 1 entrance point, be provided with the valve seat 2 suitable, enough circular valve plates 3 arranged in the described valve body 1 along space that rotating shaft 9 is rotated with circular valve plate 3 towards valve plate 3; When the described power arm 7 of cylinder pushes rotates, the crank 5 that drives in rotating shaft 9 and the rotating shaft rotates, thereby make circular valve plate 3 in valve body 1, rotate along rotating shaft 9, when valve plate 3 turns to valve seat 2 positions, valve is in closed condition, other position in valve plate 3 turns to valve body 1 is very little, and valve in opened condition.
Be provided with a support arm 6 towards valve seat on above-mentioned crank 5 and connecting rod 4 connecting end cranks 5, be provided with a stop collar 61 in the other end end of support arm 6, it is hinged with crank 5 that described connecting rod 4 passes stop collar 61.
The internal surface of above-mentioned stop collar 61 and connecting rod 4 outer surface connecting parts are gapped.
Along with the popularization of present computer, the cycle period of fixed level gas cooker is shorter and shorter, progressively reduces to 120S from early stage 180S, makes the gas cycle period originally and can also further accelerate, and main restricting factor is that valve event is too slow.And,, can reach the effect of closing tightly, opening soon as long as the length of power arm, the length of crank and the length of connecting rod are selected with respect to the present invention.For example making described piston rod stroke is 1/2 caliber, needs only 1/2 of gate valve actuation time like this, and making crank length is 1/4 of caliber, makes that impacting force is 2 times of hydraulic coupling; The amplitude of fluctuation that makes the U-shaped connecting rod is 2-3 a times of the moving width of cloth of liquid presses piston pole.So just realized the big valve of small cylinder pipe, accomplished to close tightly, opened soon.
As specific embodiments of the invention as shown in Figure 1, power hydraulic cylinder 8 can be contained on the axle of valve body either side, make the valve overall dimensions in all directions all less than 2 times of calibers, need add the local overstriking of valve at pipeline, two ends increase adpting flange, as valve body.Establish a transverse axis 9 that penetrates valve body 1 at its downside, can rotate and keep sealing, transverse axis 9 part in valve body 1 is lacked cranks 5 (can only see among the figure) near two face down bondings two of valve body, be about 1/4 of caliber, two cranks, 5 ends connect a U-shaped connecting rod (not seeing among the figure) 4, and effective length is about 1.5 times-2 times of caliber.Medial end portions are fixed a circular valve plate 3 before the connecting rod 4, an end of valve body 1 establish one can with the valve seat 2 of valve plate 3 sealings.Connecting rod 4 keeps a tilt fixing with crank 5 by a limit stoper 6,61, and connecting rod 4 can be done swing in a small amount in the gap of stop collar 61.A U-shaped power arm 7 is established in valve body 1 outside, the two ends of rotating shaft 9, and the other end of power arm connects power hydraulic cylinder.In hydraulic cylinder piston rod when action,, the propulsion power arm turns over an angle, and crank 5 in the valve body 1 and connecting rod 4 are driven turns over equal angular, and valve plate 3 is opened rapidly by closed condition; Otherwise when piston rod was withdrawn, valve plate 3 was driven valve seat 2 closed positions, although this moment, valve plate 3 was inactive, because stop collar 61 is gapped with connecting rod 4, crank pushes away connecting rod 4 before can also be little and continues to compress valve plate 3, and can not cause damage.
The valve open state is shown in dotted line: when power hydraulic cylinder 8 piston rods stretch out, outer arm rotates counterclockwise short crank 5 by transverse axis 9 transmission power, because the effect of stop collar 61, make U-shaped connecting rod 4 turn over same angle, thereby drive valve plate 3 and put a bigger amplitude, open valve rapidly, thereby speed is doubled; When closing when compressing, the power on the valve plate but is 2 times of power hydraulic cylinder pressure; Therefore as long as guarantee the intensity of member, just can guarantee the efficient operation of valve.
