Description
Technical field
The application is related to a kind of booster type valve mechanism used in a kind of electrically operated valve.
Background technology
Existing pipeline valve automation uses motor-driven valve and electromagnetic valve, because electrically operated valve uses actuator substantially
Direct drive valve element carrys out the technology of control valve keying, the shortcomings that control moment is big, and YE power consumption is big be present.
And magnetic valve carrys out control valve keying due to simple by hydraulic drives valve element, therefore valve crushing is very big, and
The problem of can not working under low hydraulic pressure, while also easily being blocked in the presence of control runner.
Because the serious utilization that have impact on pipeline valve automation of existing problem above is, it is necessary to design a kind of work(of invention
Consume valve element control structure and mode low, that driving is reliable, adaptability is high.
Following two electrically operated valves in the prior art be present accordingly：
1st, the Chinese invention patent " booster type electric regulating valve " of Patent No. 200910113225.7 discloses following knot

There is fluid passage.Valve element, valve element leather cup, water seal, screw rod and bonnet are collectively forming the counter balance pocket of a relative closure, and counter balance pocket is only
Communicated by the runner of valve element with fluid intake.Screw rod is connected with drive mechanism, and drive mechanism can be done by screw rod with movable valve plug
Linear motion.Valve element can be blocked in block fluid motion between fluid intake and fluid issuing by moving downward, and reach out
The effect of closing valve.Due to the presence of counter balance pocket, pressure of the fluid to valve element is balanced so that the resistance of motion of valve element diminishes.
So reduce the torque and energy consumption needed for controlled valve.Simple in construction, compact, small volume of the invention, transmission efficiency, control
Accurately, reliability is extremely strong.But it equally exists high to screw strength requirement, easily make when water pressure fluctuations and impact of water hammer valve element
The problem of being damaged into screw rod.

Enclosed cavity forms pressure chamber C；Other one in threeway leads to for intake antrum B, empty in the valve body 1 in addition to intake antrum B and pressure chamber C
Chamber is water chamber A；The upper port of valve element 3 is semiclosed, the inlet opening 10 for offering to turn on intake antrum B on valve element 3, to
The osculum 11 turned on water chamber A, is provided with the valve 4 that can block osculum 11 at osculum 11, and the valve 4 passes through
The control lifting of drive mechanism 9 being connected to outside valve body 1, valve 4 can lift when lifting with movable valve plug 3.
Stroke gap is left between osculum 11 and valve element 3 upper port, the valve 4 is arranged in the trip gap.
Valve 4 can be with the osculum 11 on clogging valve element 3, when 4 clogging valve of valve when being located at the lower end in stroke gap
During osculum 11 on core 3, water chamber A is blocked with connecting for pressure chamber C；Valve 4 can be pressed when continuing downward valve element 3 to
Lower motion, until valve element 3 blocks intake antrum B and water chamber A connection, valve is closed.
When valve 4 is located at the upper end in stroke gap, the osculum 11 on valve element 3 is opened, and water chamber A and pressure chamber C connect
It is logical；Valve 4 can pull valve element to move upwards when continuing up, and intake antrum B connects with water chamber A, valve opening.
As shown in figure 1, the drive mechanism 9 is prior art, it can be motor, the power output of drive mechanism 9
Hold and be connected with stretching into pressure chamber C screw mandrel 5, rotation set has pressing plate 6 on screw mandrel 5, and the lower end of pressing plate 6 is equiped with buffer spring 7, buffering
The lower end of spring 7 is connected with valve 4.
As shown in Fig. 2 the clutch end of drive mechanism 9 is connected with stretching into pressure chamber C screw mandrel 5, screw mandrel 5 passes through valve
4 are spun with being arranged on the pressing plate 6 of the lower section of valve 4, and buffer spring 7 is provided with the screw mandrel 5 between pressing plate 6 and valve 4.
By way of above two screw mandrel 5 drives valve, it can effectively be reduced and be acted on valve 4 by buffer spring 7
Power, screw mandrel 5 is played a very good protection.
The valve 4 has the valve body of closure osculum 11, and the valve body is flat thin plate.
Filter screen 14 is provided with the inlet opening 10 and osculum 11.
Sealing ring 12 is provided with the inner port of osculum 11, sealing ring 12 can be with the fitted seal of valve 4.
Screw mandrel 5 and the junction of valve body 1 are provided with sealing device 13, the sealing device 13 can be sealing ring.
The course of work and principle of the application is as follows：During valve-closed state, row that valve 4 blocks on core assembly 3
Water hole 11, it is downward pressure that pressure chamber C and intake antrum B, which puts on the pressure differential of core assembly 3,；Between intake antrum B and water chamber A
Blocked by core assembly 3, valve is closed.
Valve enters opening process from closing：First, the drive screw 5 of drive mechanism 9 is rotated, and pressing plate 6 is done directly upwards therewith
Line moves；Pressing plate 6 stretches buffer spring 7, the lower end of buffer spring 7 pulls valve 4 to move upwardly together；Due to valve 4 and valve element
The presence in the stroke gap of component 3, valve 4 open the osculum 11 on core assembly 3 in advance, and pressure chamber C liquid passes through row
Water hole 11 is released to water chamber A；Pressure chamber C pressure declines, pressure chamber C and intake antrum B put on the pressure differential of core assembly 3 to
Under pressure start to be converted to and upward pressure；Valve 4 continues up pulling core assembly 3 and moved upwards, and valve is opened.
Valve is from turning on into closing process：First, the drive screw 5 of drive mechanism 9 is rotated, and pressing plate 6 is done downwards directly therewith
Line moves；Pressing plate 6 extrudes buffer spring 7, buffer spring 7 promotes valve 4 to move downwardly together；Due to valve 4 and core assembly 3
Stroke gap presence, the lower end of buffer spring 7 promotes valve 4 to block osculum 11 on core assembly 3, pressure chamber in advance
C pressure raises；Pressure chamber C and intake antrum B puts on the pressure differential of core assembly 3 by being converted to downward pressure upwarding pressure
Power；Valve 4, which continues traveling downwardly, promotes core assembly 3 to move downward, and valve is closed.
During valve opening or closing, first pass through drive mechanism 9 and drive valve 4 to rise or fall to osculum 11
Open or obstruction, the pressure in pressure chamber C first adjusted by the connection with water chamber A or obstruction, after driven by drive mechanism 9
Valve 4, and risen or fallen with movable valve plug 3, while pass through the pressure differential auxiliary adjustment valve element 3 between intake antrum B and pressure chamber C
The present position in valve body 1, is finally completed and is turned on and off valve.
In valve opening or closing process, by drive mechanism 9 control the swing of screw mandrel 5, the rising of governor valve 4 or
Dropping distance, and then the distance that core assembly 3 rises or falls is limited by valve 4, so as to complete the overall aperture of valve
Control.When valve 4 is spacing to core assembly 3, core assembly 3 is acted on by the pressure of water in valve body 1, is reached in valve body 1 certainly
Balance.Regulation to valve opening, it is the critical function that the application is different from prior art, it realizes low power consumption flow rate
The purpose of regulation.
Above technical characteristic constitutes the most preferred embodiment of the application, and there is stronger adaptability and optimal implementation to imitate for it
Fruit, can be according to the inessential technical characteristic of increase and decrease be actually needed, to meet the needs of different situations.
