Abstract
One-way valve (4) can have axle (11) swing of certain distance around distance one-way valve (4) edge.In addition, one-way valve (4) is connected with a supporting arm (9) that curves 90 ° of arcs, and being equipped with one on the supporting arm (9) can be around the contiguous block (10) of axle (11) swing.On the supporting member (12) of arc supporting arm (9) upper end, bolt (13) is housed, it is perpendicular to one-way valve (4) plane, and supporting counterweight (14 and 16), wherein counterweight (14) can vertically move and live in certain fixed-site along bolt (13), the total centre of gravity of total movement quality point-blank moves when counterweight (14) is mobile, this straight-line pass running shaft (11) and perpendicular to one-way valve (4) plane.
Description
The present invention relates to a kind of one-way valve that is supporting swingably, it for example is contained in the air flow path in order to seal a hole, this hole or opening under normal conditions, and the energy by means of air-flow is automatically closed it by valve when flow rate ratio changes; Perhaps by valve closing under normal conditions, and when pressure raising or pressure decline, open.Under any circumstance all require when changing the flow area in hole, to change the position of valve, must on valve, act on certain power for this reason.Owing to varying in size of valve location angle makes valve weight desired adjustment power is produced different influences.
Known sealed valve all is to swing around the axle parallel with the horizontal valve edge on its top, so the total weight of valve is all had an effect when mobile, therefore the valve that is supporting like this is for the variation of air-flow, no matter be that variation in pressure or change in flow reaction are all very blunt.
The objective of the invention is to introduce a kind of one-way valve that is supporting swingably, this one-way valve can be reacted to small variations in flow, and can for example transfer the closed position that can guarantee necessary sealing to by open position apace, and when having small inverse change, air-flow still can carry out the transition to open position continuously from closed position.
The purpose that proposes in order to reach, the present invention advises installing a supporting arm, and it is fixed on the center of valve and can winds a supporting axle swing that has with a certain distance from the valve edge; And install a movable balance weight, and make valve can utilize adjustable trying hard to keep to be held on the position and when moving this counterweight, to make the total centre of gravity of moving-mass to move point-blank, this straight line is through running shaft and perpendicular to the valve plane.
By one-way valve structures of the present invention, valve is opened to such an extent that big more restoring moment is just more little.This fact can guarantee valve is opened greatly as much as possible.
By structure of the present invention one-way valve is pressed on the seamed edge that elastic sealing device is housed on the valve base by means of the sealing of a smaller overbottom pressure with necessity.The requirement of sealing is also additionally by guaranteeing in the configuration of the valve supporting of valve outside and the calculating beyond the channel system by the present invention.Bearing friction power on axle is more little, and it is just more little to handle the required power of valve.For example adopt ball bearing or other similar supporting meanss for this reason.
By a kind of structural type of the present invention, supporting arm curves 90 ° arc in a vertical plane, a contiguous block perpendicular to the valve plane is housed above it, and that end bearing that is deviating from supporting arm on the contiguous block is on axle.
At last, in the structural type of the present invention, one and the parallel plane supporting member of valve are housed also on supporting arm or contiguous block, have adorned a bolt vertical with the valve plane on its free end, counterweight can move on bolt or be fixed.
By this structural type; one-way cock of the present invention can be assembled with fairly simple part; especially can also arrange the position of axle like this; be that it all is positioned within the protection housing with contiguous block and swing arm, have only supporting member and just give prominence on housing with the bolt of counterweight.
It shown in the figure one-way valve embodiment's of the present invention side view.Below it is elaborated.
Housing of expressing with vertical section 1 and the valve base 2 usefulness flanges of also expressing with vertical section couple together.Hole 3 is closed by one-way valve 4, and one-way valve 4 is pressed on the elastic sealing device 6 of the groove 5 that places valve base 2 with its periphery in shown position.
Center at one-way valve 4 is fixed on one-way valve on the thread section 8 of supporting arm 9 with nut 7.
Supporting arm 9 curves 90 ° of arcs in vertical plane, a contiguous block 10 perpendicular to valve 4 planes is equipped with in its upper end, and contiguous block 10 is not by being bearing in swingably on the axle 11 at the ball bearing of representing on the figure.
Fixed the supporting member 12 of a dihedral with screw thread in the upper end of supporting arm 9, its arm is parallel to valve 4 planes.
Fixed a bolt 13 perpendicular to valve 4 planes on supporting member 12, the top of it is equipped with a counterweight 14 movably, and can be fixed by nut 15.Bolt 13 passes supporting member 12, and is supporting another counterweight 16 in the opposite end of counterweight 14, with nut 17 it and supporting member 12 is fixed together on bolt 13.So just, obtained an a kind of favourable structure that satisfies basic demand of the present invention, promptly when mobile counterweight 14, the total centre of gravity of all moving-mass point-blank moves, and this straight-line pass running shaft and perpendicular to valve 4 planes meanwhile can be selected restoring force in very wide scope.
By housing 18 that express with vertical section, upper and lower opening, not only can hole 3 be covered in, and protect axle 11 relevant parts with it with corresponding distance.
Claims (3)
1, the one-way valve that is supporting swingably, it is characterized in that: in the center fixation of one-way valve (4) supporting arm (9), it can have the swing of the axle (11) of certain distance around being bearing in apart from the edge of one-way valve (4), and installed a movable balance weight (14), make one-way valve (14) can remain on the position by an adjustable power, and the total centre of gravity of total movement quality moves on a straight line when mobile counterweight (14), this root straight-line pass running shaft and perpendicular to one-way valve (4) plane.
2, according to the described one-way valve of claim 1, it is characterized in that: supporting arm (9) curves 90 ° of arcs in a vertical plane, and a contiguous block (10) perpendicular to one-way valve (4) plane is housed thereon, that end bearing that deviates from supporting arm (9) of contiguous block (10) is on axle (11).
3, according to claim 1 and 2 described one-way valves, it is characterized in that: on supporting arm (9) or contiguous block (10), connected one and the parallel plane supporting member of one-way valve (4) (12), bolt 13 perpendicular to one-way valve (4) plane is housed on the free end of supporting member (12), removable and fixable counterweight (14) is arranged on bolt (13).
