Abstract
A kind of slow Vertical Lift Check Valves for opening Slow Close comprising the valve body of tubular（1）, valve seat is equipped at the import position of valve body（2）, flap is shelved at the top of valve seat（3）, guide sleeve is equipped in the top of flap（4）, guide sleeve passes through spoke（5）It is connected on the inner wall of valve body, the guide rod on flap（6）It is inserted in guide sleeve；It is characterized in that guide sleeve is tubbiness, the blind end of guide sleeve upward, the pilot hole on blind end（9）It is matched with guide rod, spiral winding is fixedly provided in guide sleeve（8）, the both ends of spiral winding are in parallel, and the middle part of guide rod is fixedly cased with magnet steel（7）, magnet steel is located in spiral winding.During valve opening or closing, the magnetic force line cutting spiral winding of the magnet steel on guide rod induces electric current in spiral winding, and resistance is generated to the movement of magnet steel, so that check-valves is realized and slowly opens or slowly closing.
Description
Technical field
The utility model is related to a kind of Vertical Lift Check Valves.
Background technology
Vertical Lift Check Valves are used for preventing fluid media (medium) reverse flow, the structures of Vertical Lift Check Valves generally comprise valve body, flap,
Valve seat, fluid media (medium) positive pressure keep flap opening valve logical, and fluid media (medium) buffer brake makes flap be closed with valve seat contact valve；
The speed that the check-valves of this structure opens and closes all quickly, will produce water hammer effect and be damaged to pipe-line system.
Utility model content
In view of the deficiencies of the prior art, the utility model proposes a kind of slow Vertical Lift Check Valves for opening Slow Close, which exists
Meeting generates damping to the action of spool during being turned on and off, and check-valves is made to realize slowly unlatching or slowly closing.
The technical solution of the utility model is a kind of slow Vertical Lift Check Valves for opening Slow Close comprising the valve body 1 of tubular,
The import position of valve body is equipped with valve seat 2, and flap 3 is shelved at the top of valve seat, is equipped with guide sleeve 4 in the top of flap, is oriented to
Set is connected to by spoke 5 on the inner wall of valve body, and the guide rod 6 on flap is inserted in guide sleeve；It is characterized in that guide sleeve is bucket
Shape, upward, the pilot hole 9 on blind end matches the blind end of guide sleeve with guide rod, and spiral is fixedly provided in guide sleeve
The both ends of coil 8, spiral winding are in parallel, and the middle part of guide rod is fixedly cased with magnet steel 7, and magnet steel is located in spiral winding.
The utility model is characterized in that during valve opening or closing, guide rod moves simultaneously with flap, is oriented to
The magnetic force line cutting spiral winding of magnet steel on bar, spiral winding both ends are in parallel, electric current induced in spiral winding, to magnet steel
Movement generate resistance, the speed of magnet steel movement is faster, induces that electric current is bigger in spiral winding, to the resistance of motion of magnet steel
Also bigger, so that check-valves is realized slowly unlatching or slowly closing.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Attached drawing mark indicates respectively：1- valve bodies, 2- valve seats, 3- flaps, 4- guide sleeves, 5- spokes, 6- guide rods, 7- magnetic
Steel, 8- spiral windings, 9- pilot holes.
Specific implementation mode
In conjunction with description of the drawings specific embodiment of the present utility model.
A kind of slow Vertical Lift Check Valves for opening Slow Close comprising the valve body 1 of tubular is equipped with valve seat 2 at the import position of valve body,
It is shelved with flap 3 at the top of valve seat, is equipped with guide sleeve 4 in the top of flap, guide sleeve is connected to by spoke 5 in valve body
On wall, the guide rod 6 on flap is inserted in guide sleeve；It is characterized in that guide sleeve is tubbiness, the blind end of guide sleeve upward, seals
Pilot hole 9 on closed end is matched with guide rod, and spiral winding 8 is fixedly provided in guide sleeve, and the both ends of spiral winding are in parallel,
The middle part of guide rod is fixedly cased with magnet steel 7, and magnet steel is located in spiral winding.
During valve opening or closing, guide rod moves simultaneously with flap, the magnetic line of force of the magnet steel on guide rod
Cutting auger coil, spiral winding both ends are in parallel, and electric current is induced in spiral winding, and resistance, magnetic are generated to the movement of magnet steel
The speed of steel movement is faster, induces that electric current is bigger in spiral winding, also bigger to the resistance of motion of magnet steel, keeps check-valves real
Now slow unlatching or slowly closing.
