Abstract
The utility model relates to an integrated linking switching device for a plurality of valves. The utility model is characterized in that a start and stop valve rod (core) of each valve is connected with a mechanical actuator which comprises a rotatable screw rod, a moving screw nut block which can be matched with the screw rod through threads and can only move along the axial direction of the screw rod and a rod which is connected with the screw nut block and drives the start and stop of the valve rod (core). Because the utility model adopts a mechanical switching device to drive a plurality of valves to open and close simultaneously, the defects which are caused by actuators which are arranged on each valve are eliminated. The utility model has the advantages of simple structure, low cost, reliable motion, large start and stop force moment, etc.
Description
Model utility is the switch gear about valve, the integrated coupled switch device of particularly a plurality of valves.
In the control of industrial field pipeline, often having needs a plurality of valves to switch simultaneously automatically, moves switchings simultaneously for reaching several valves, and prior art often adopts a plurality of solenoid valve or mortor operated valves with independent control switch function to make up, by to each valve actuating mechanism power supply exchange, realize that many valves switch simultaneously.The grouped controls of valve more than this kind because each valve all carries open and close actuator, make that the combination cost is higher, and cost are along with the increase of using valve quantity is linear growth; Next carries the solenoid valve of actuator or mortor operated valve owing to have electric elements, generally can not use in corrosive environment, has also just limited the expansion of using the field; When this besides valve combination is used, often be prone to because of a valve actuating mechanism (especially solenoid valve) wherein breaks down, and influence switch synchronously need.In addition, carry and open and close actuator's valve, keying moment is generally less, is not suitable for big caliber or high-pressure liquid occasion and uses.
The purpose of model utility is to overcome the deficiency of above-mentioned prior art, provide a kind of simple in structure, cost is low, it is big to open and close moment, uses, reliable in action not fragile, many valves of reduced-maintenance integrated control device.
The model utility purpose realizes that basic design is by a rotary screw rod, drives with it screw-thread fit and can only be along the mobile spiral shell nurse piece of screw mandrel axial motion, and mobile spiral shell nurse piece is by rod member or directly drive (rotating or pulling) opening/shutting valve.According to above-mentioned design, many valves of model utility coupled switch device, comprise a plurality of valves that are provided with on demand, it is characterized in that described each valve opening and closing valve rod (core) links to each other with a mechanical actuating mechanism, described mechanical actuating mechanism comprises rotating screw mandrel, cooperate also and can only connect the rod member that spiral shell nurse piece actuate valve stem (core) opens and closes with wire rod thread along the mobile spiral shell nurse piece of screw mandrel axial motion.Like this, the screw mandrel of rotation drives spiral shell nurse piece and axially moves back and forth along the silk stalk, and the moving back and forth of spiral shell nurse piece drives that rod member rotates or pulling valve rod (core), thus switching when realizing a plurality of valve open and close.
Further specify model utility below in conjunction with accompanying drawing and two kinds of exemplary embodiment.
Fig. 1, Fig. 2 are respectively the axial and plan structure schematic representation that rotates a kind of mode of execution of open valve.
Fig. 3 is a kind of mode of execution plan structure of a kind of slip poppet valve schematic representation.
Mode of execution one; Referring to Fig. 1,2, on support 1, be fixed with guide rod 2 and screw mandrel 3, guide rod effect one is that guiding spiral shell nurse prevents to rotate, two can increase the stability that the spiral shell nurse moves.The spiral shell nurse piece 4 that screw-thread fit is arranged on the screw mandrel 3, spiral shell nurse piece 4 rotates and axially moves back and forth according to screw mandrel under guide rod 2 guiding.The quantity of spiral shell nurse piece is according to the quantity of valve and position and decide.Spiral shell nurse piece 4 flexibly connects by the rod member 7 of pin 6 with band chute 8, and rod member 7 one ends are fixedlyed connected with the valve rod 10 of 90 ° of rotary opening and closing valves 5 (as butterfly valve, ball valve).Screw mandrel is driven by motor 9 and rotates, and at opening of valves and closed condition position return of stroke switch (not providing among the figure) is set.The original state of valve is set according to the pilot line needs.Motor 9 drives screw mandrel 3 rotations during work, the screw mandrel that rotates makes spiral shell nurse piece 4 move at guide rod 2 guiding lower edge screw mandrels, the spiral shell piece that moves moves in chute 8 by the pin 6 that stretches out, and rod member 7 is rotated, because valve body is fixed around valve rod, the rod member actuate valve stem of rotating is rotated, realize the unlatching of valve, when opening of valves is put maximum position, mobile spiral shell piece touches the return of stroke switch, motor stops operating, and makes the power supply commutation.The rear motor backward rotation of switching on once more drives valve and closes.
Mode of execution two; Referring to Fig. 3, as enforcement mode one, valve 5 is the slip poppet valve, and pull bar 7 is with valve 5 and spiral shell nurse piece 4 fixedlys connected.When motor 9 rotated, spiral shell nurse piece one side valve core was pulled out opening of valves, and the opposite side spool pushes valve and closes.
Above-mentioned mode of execution also can omit pull bar, and spool directly is connected with spiral shell nurse piece.
Spiral shell nurse piece is connected with rod member or valve and has limited its rotation, omits guide rod, can force spiral shell nurse piece to rotate and move axially according to screw mandrel equally.In addition, guiding keyway etc. can also be set on screw mandrel, also can reach moving axially of spiral shell nurse piece.And adopt double lead or forward lead screw or the like, belong to the utility model design equally.
Model utility is owing to adopt an aforementioned cover mechanical switching device, exempt each valve and carry actuator, can realize equally that not only many valves interlock switches, and simple in structure, cost is low, reliable in action, not fragile, especially have the bigger moment that opens and closes, more be applicable to heavy caliber and high-pressure fluid pipes.And any big or small unlatching that can realize valve, to satisfy the control flow rate needs.
For convenience of description, the described valve keying of specification is a synonym with switch.
