Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
It should be noted that term " first ", " second " are used for description purposes only, it is not understood to indicate or imply phase
To importance or implicitly indicate the quantity of indicated technical characteristic.Define " first " as a result, the feature of " second " can be with
Explicitly or implicitly include one or more of the features.
As shown in Figs 1-4, the check-valves of a kind of valve block fast lifting of the utility model, including chassis 10, trigger valve 30
(valve block) and cylinder 30, several discharge orifices 14 are offered on the side wall on chassis 10, and the top on chassis 10 is downwardly projecting
Arc sealing plate 11 offers mounting hole 12 on the lowest part of arc sealing plate 11, is evenly distributed with around mounting hole 12 several
Through-hole 13, trigger valve 20 is inserted into mounting hole 12, and trigger valve 20 is in 12 upper direction of mounting hole, the uppermost limit of trigger valve 30
It is connected with the cylinder 30 of top hollow out, cylinder 30 covers in outside chassis 10 and agrees with 10 phase of chassis.
Trigger valve 20 includes connecting column 21 and rocker piece 22, and chassis 10 passes through connecting column 21(cylinder axle center) and cylinder
30 are connected, and the bottom of rocker piece 22 is arc, and the radian of rocker piece 22 is matched with the radian of arc sealing plate 11.Rocker piece
Moving up for small distance can be carried out on arc sealing plate, when cylinder declines and with chassis to when agreeing with, because of rocker piece
The distance walked is short, will not generate water hammer effect, has good muting function.
The bottom margin on chassis 10 is equipped with the first buckling plate 15 outwardly protruded, and the bottom margin of cylinder 30 is equipped with outside
Second buckling plate 33 of protrusion, when rocker piece 22 is fallen on arc sealing plate 11, the first buckling plate 15 and the second buckling plate 33
Agree with.The setting of first buckling plate and the second buckling plate forms confined space, prevents water so that chassis is more agreed with cylinder
The refluence of stream.
The top of cylinder 30 is equipped with limit hole 21, is equipped with several brackets 32 being connected with side wall around limit hole 21,
Limit hole 21 and bracket 32 are integrally formed, and the quantity of bracket 32 is 3, on the corresponding position of mounting hole 12, arc sealing
The back of plate 11 is equipped with the fixed column 16 of protrusion.The connecting column of trigger valve is connected by limit hole with cylinder, and fixed column is set
Set and preferably secure connecting column, make that its is pliable, fracture, 3 brackets of limit hole integrally connected formed one it is stable
Triangular supports keep limit hole more stable.
The quantity of through-hole 13 is 4.Through-hole is much smaller compared with the size of discharge orifice, water can be made to circulate faster, leads to
The number in hole can also be depending on the size of arc sealing plate.
The work step of the utility model is as follows:
When flowing water enters chassis 10, water can pass through through-hole 13, and then the impulse force of water can promote trigger valve 20, also drive
It is promoted and limits the cylinder 30 to link together with trigger valve 20, the flowing water near chassis 10 pours into the rectangular of chassis 10 at once
Elliptical flowing water mouth 14.After pumping systems stop operating, trigger valve 20 because the pressure applied of water column that flows backwards and
Sedimentation downwards, the second buckling plate 33 of cylinder 30 are leaned on from the first buckling plate 15 for dropping to chassis 10 that hangs down, fluid resistance system
Number is smaller, and four through-holes 13 on chassis 10 are just closed quickly, while cylinder 30 is also the flowing water of all 10 both sides of chassis
Hole 14 is closed, and plays a part of to prevent water adverse current, check-valves can prevent the aqueous reflux for having entered discharge orifice 14 from flowing away quickly.
Valve after the utility model improvement is no longer one piece of one side disk outstanding, and replacing is an opening reversion
Cylinder, cylinder opening part round edge material it is thinner than cylinder material itself, compare the weight of entire cylinder
Lightly, check-valves is the periphery of cylinder itself by the part of hydraulic pressure, is effectively reduced the loss of check-valves, utilizes the floating of water
Power works, and reduces the friction and loss of connecting column, meanwhile, the utility model possesses particularly good muting function, opens
The advantages of short no water hammer effect of distance that dynamic valve is walked, installation is required without orientation, therefore practicability significantly improves, structure is simple,
It is easy to operate, it can be widely applied in the technical field of various fluid lines.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
Illustrative description is carried out to the utility model patent above in conjunction with attached drawing, it is clear that the reality of the utility model patent
It is now not subject to the restrictions described above, as long as being carried out using the method concept and technical solution of the utility model patent various
Improve, or it is not improved the conception and technical scheme of the utility model patent are directly applied into other occasions, in this reality
With in novel protection scope.
