After reducing motor energising, its output shaft circles, the crank being mated also rotates, and crank swings by crank hinge drivening rod, and connecting rod drives valve core movement by connecting rod link, add spacing to spool of linear bearing, realize the straight reciprocating motion of spool.Valve seat endoporus is divided into a plurality of chambers by O type circle, adds coordinating of O type circle and spool, and making each cavity is relatively independent sealing.When spool to-and-fro motion, perforate on its sidewall will be along with spool together to-and-fro motion between each chamber, when spool stop motion, the chamber at now spool perforate place will connect mouth by spool cavity and entrance (outlet) and be communicated with extraneous realization, and outlet (entrance) is also installed on valve seat sidewall corresponding to this cavity, connect mouth, can realize two connections between passage.When motor continues rotation, spool can continue straight line motion, when the perforate on spool sidewall arrives another chamber, can realize the perforation with another passage.
In order to make spool can be communicated with accurately two passages at every turn, namely allow perforate on spool sidewall can accurately be parked in the central position of chamber, on the connecting rod link coordinating with spool, be processed with probe, this probe can be realized and being synchronized with the movement of spool, the corresponding slot optical coupling of respective numbers of installing on the movement locus of probe, the spool side opening that makes corresponding to position of each slot optical coupling rests in the middle of corresponding chambers.The perforation that has realized passage when sensing probe, slot optical coupling is described when work, the slot optical coupling of diverse location is located corresponding chamber, each passage successively not only can be linked in sequence during actual use, also can optionally connect needed passage, motor stalling while only needing to control corresponding slot optical coupling position.
Compared with prior art, its advantage is the utility model:
1, simple in structure, cost is lower.The prime cost of this mechanical type modulating valve comes from the processing charges of each part, the cost of reducing motor and sensor is relatively low, but with respect to the cost of solenoid valve, the cost of this model utility also can reduce greatly, especially passage is more, and relative cost is lower.The member that these modulating valve component are all comparison basis in addition, relatively simple for structure, turn formula just.
2, expansivity is strong.The expansivity of this modulating valve is very strong, only needs the simple structure that increases the size of corresponding part and change corresponding part, and the cost increasing amount that it causes is relatively less.The expansion of one-to-many can be realized, being communicated with successively of an import and a plurality of outlets or being communicated with successively of outlet and a plurality of imports can be realized.
3, long working life.The solenoid valve of comparing, operational noise of the present utility model is smaller, during work, do not need to switch on always, thus also corresponding raising of operating life.
4, Overall Power Consumption is few.Respective channel can stop operating reducing motor after connecting, and the solenoid valve of comparing needs always in running order situation, and energy consumption reaches minimizing.
5, volume is little, lightweight.
