Description
Technical field
The invention belongs to regulating valve technical fields.
Background technique
Self-operated valve, as driven by energy valve automatic work, does not need outer by the pressure itself of the medium in flowing through
Connect power supply and secondary meter.Direct-operated regulator all utilizes the feedback signal (pressure, pressure difference, temperature) of valve output end to pass through signal
Pipe is transmitted to the aperture that executing agency's driving flap changes valve, achievees the purpose that adjust pressure, flow, temperature.
Existing direct-operated regulator structure includes valve body, spool, adjusting rod, executing agency, feedback mechanism, control pipe
Line is wherein provided with valve road in valve body, spool is mounted in the valve port of valve road, spool make when moving up and down valve port open or
Close, the movement of spool is controlled by adjusting rod, and adjusting rod connect with executing agency, control pipeline be connected to valve road intake antrum with
Feedback mechanism, the output end of feedback mechanism are connect with structure is executed, and principle is that the water in intake antrum enters control after throttling
Pipeline, when the hydraulic pressure of intake antrum is larger, signal is fed back to feedback mechanism by the hydraulic pressure controlled in pipeline, so that be attached thereto
Executing structure drives adjusting rod to move down, and spool turns down valve port, conversely, spool closes valve port when the hydraulic pressure of intake antrum is smaller
It is small.Existing feedback mechanism includes that shell inner cavity is divided into upper chamber and lower chambers by shell, the diaphragm in shell, and bottom chamber is sliding
It is dynamic to be combined with the movable plate connecting with execution structure, return spring is provided between diaphragm and movable plate, upper chamber and control are managed
Line communicates, and the variation in water pressure of upper chamber makes diaphragm deformation, overcomes the elastic force of spring and movable plate is pushed to slide.
The shortcomings that above scheme, is: in certain mechanisms, needing according to the speed of water flow come intermittent control valve core
Unlatching, when as larger such as water velocity, spool open frequency (i.e. spool movement speed) is high, and when water velocity is lower, spool is opened
The frequency (i.e. spool movement speed) opened is low.Now there are no the structure appearance for being able to satisfy above functions in current regulating valve.
Summary of the invention
The invention is intended to provide according to water velocity the valve for adjusting the adjustable opening and closing frequency of spool movement speed.
The valve of adjustable opening and closing frequency in this programme, including valve body, the intracorporal intake antrum of valve and water chamber pass through valve
Mouth connection, spool are mounted at the valve port and valve port are opened and closed by valve rod driving, further include executing agency and feedback mechanism, hold
Row mechanism includes that executing agency includes being combined to form installation cavity by upper cover and lower cover, has pressing plate in the installation cavity and connects with pressing plate
The execution bar connect, the execution bar lower end are fixedly connected with valve rod by sleeve, are executed the upper end of bar and are connected through upper cover and with idler wheel
It connects, return spring is disposed between pressing plate and lower cover；Feedback mechanism includes the impeller being arranged in intake antrum, the shaft of the impeller
It is keyed with umbrella tooth, upper cover top surface is welded with mounting base, and being rotatably assorted in the mounting base has cross bar, the cone tooth and umbrella of cross bar one end
Tooth engagement, the other end of cross bar are fixed with the cam contacted with idler wheel.
The utility model has the advantages that water flow will push wheel rotation when water flow enters intake antrum, wheel rotation makes shaft drive umbrella
Tooth rotation, to bore tooth rotation and rotate with moving cam, when cam rotation, its convex surface makes idler wheel is intermittent to move down, idler wheel
Overcome the elastic force of return spring that spool is made to progressively close off valve port when moving down, conversely, returning when the basal plane of cam and idler wheel contact
So that valve rod moves up, spool is gradually opened valve port for position spring effect.The present invention can directly adjust impeller according to water velocity
Velocity of rotation, when water velocity is larger, spool open frequency is high (i.e. spool movement speed is fast), when water velocity is lower, spool
The frequency of unlatching is low (i.e. spool movement speed is slow), and the present invention can adjust spool movement speed according to water velocity, interval
Property control valve port opening and closing.
Further, the needle bearing with cross bar cooperation is provided in the mounting base, so that cross bar rotation is more steady.
Further, the described sleeve includes screw thread inner cavity, executes bar lower end and from top to bottom screws in screw thread inner cavity and pass through
Nut check, valve rod upper end screw in screw thread inner cavity from the bottom to top and by nut checks, connect it is stronger, and execute bar and
Valve rod is not susceptible to misplace, and power transmission efficiency is higher.
Further, the number of the return spring is two groups, and symmetrical as center line to execute bar, and restoring force is more
Greatly, it is fast to reply speed.
Further, the position of the valve rod and valve body contact is equipped with gland packing box, prevents medium with the shifting of valve rod
Dynamic to be brought into valve body, sealing effect is more preferable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the valve of the adjustable opening and closing frequency of the embodiment of the present invention.
