Specific embodiment
Below in conjunction with specific embodiment, invention is further described in detail.It should be appreciated that described herein specific
Embodiment is only used to explain the present invention, is not intended to limit the present invention.
With reference to shown in Fig. 1-3, a kind of irrigate uses valve actuator, including diaphragm dome 2, diaphragm 3, connecting plate 4, first
Connector 10, the second connector 6 and water seal cover 8；The diaphragm dome 2 is set to the top of the diaphragm 3, first connection
Part 10 is set to the lower section of the diaphragm 3 and is connect the diaphragm dome 2 with the diaphragm 3 by screw thread, can guarantee every
Film is preferably fitted and connected with the first connector 10；Second connector 6 is set to the top of the water seal cover 8；The company
Fishplate bar 4 is connect by bolt 5 with first connector 10 and the second connector 6；In the above-described embodiments, first connection
Part 10, the second connector 6 one end can be connector with holes, the other end be threaded screw rod.
Seal gasket 7 is installed, the seal gasket 7 is set to envelope between second connector 6 and the water seal cover 8
The top of water cover 8, and water seal cover 8 and second connector 6 are linked into an integrated entity by the screw thread of the second connector 6, wherein
The seal gasket 7 is hollow annulus, and the periphery of annulus is equipped with groove, and the outer edge length of groove is relatively long, can be incited somebody to action
The outer edge of water seal cover 8 covers, and guarantees the sealing performance of valve；After diaphragm 3 is squeezed by water flow to be risen, first connector
10 drive connecting plate 4 and the second connector 6, cause the upper surface of water seal cover 8 that can coincide with the sewage draining exit of valve body, sealant
Pad 7 can uniform stressed, make valve inlet and outlet be connected to.
3 outer edge of diaphragm is provided with positioning hole 1, and better cooperation can be formed with valve body, and the diaphragm 3 is
Although diaphragm of rubber material has the toughness of rubber but in pressure-bearing and without ductility, the upper end of first connector 10
The positioning hole 1 for being equipped with spigot-and-socket with one end of diaphragm 3 can more preferably coincide with diaphragm 3.
The connecting plate 4 is made of two pieces of stainless steel plates, inside be hollow interlock plate, in valve working water flow along
Stainless steel plate panel flows through, and greatly reduces connecting plate 4 to the inhibition of water flow, to reduce the water resistance of valve；It is described simultaneously
Bolt 5 is band riveting bolt pin shaft, and the first connector 10 and the second connector 6 are connected to integral, fortune by band riveting bolt pin shaft
It can turn at riveting during row.
The surrounding distribution design of the water seal cover 8 has locating slot 9, it is ensured that water seal cover 8 moves in scheduled position, into one
Step guarantees the sealing station of seal gasket 7, greatly improves the sealing performance and reliability of valve.
In the above-described embodiments, the diaphragm 3 be " recessed " type canvas filler rubber diaphragm, using " recessed " though type canvas filler rubber diaphragm
Toughness with rubber does not have biggish deformation quantity still in pressure-bearing；" recessed " type canvas filler rubber diaphragm 3 can be with valve valve
Lid composition one can be with the cavity of pressure-bearing, when pressure-bearing in cavity, the outside of " recessed " type canvas filler rubber diaphragm 3 and valve body dependent part
Part brought close is to have the function that block water flow；When in cavity not at pressure, hydraulic pressure presses " recessed " type canvas filler rubber diaphragm 3
To fitting like a glove with valve deck inner surface, to open channel for water flow.
Valve run when valve driving device be that the purpose of control valve is realized by mode below, when diaphragm 3 with
When being full of water with pressure or compressed gas in the cavity that valve deck is formed, diaphragm 3 expands under the effect of the pressure, the expanding noodles of formation
The import of valve is fully sealed with the partition of valve, diaphragm 3 drives connecting plate 4 that water seal cover 8 is forced to move downward, to open
The sewage draining exit of valve completes the switching in water route；When the inside cavity that diaphragm 3 and valve deck are formed is without pressure or equal with ambient pressure
When, the immense pressure of water flow jacks up diaphragm 3 upwards in valve, so that diaphragm 3 is fit together with valve cap of valve, the rising of diaphragm 3
Diaphragm dome 2 is driven, diaphragm dome 2 drives connecting plate 4, and then water seal cover 8 moves upwards, and water seal cover 8 is in scheduled track
Operation completes the closing of valve sewage draining exit to sewage draining exit under the action of seal gasket 7；It is agricultural irrigation two-bit triplet above
Valve completes whole movements of a valve opening and closing water route switching by valve actuator.
The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
