Description
Technical field
This utility model relates to pump, is specially a kind of pump valve.
Background technology
Pump is conveying liquid or the machinery making fluid pressurization.It sends mechanical energy or other external energies of prime mover to liquid, makes liquid energy increase.Pump is mainly used to carry the liquid such as water, oil, acid & alkali liquid, emulsion, suspended emulsion and liquid metal, it is possible to conveying liquid, gas mixture and the liquid containing suspended solids.Pump generally can be divided into positive displacement pump, dynamical type pump and other types pump three class by operation principle.In addition to classifying by operation principle, also can be by additive method classification and name.As, electrodynamic pump and turbine pump etc. can be divided into by driving method；Single-stage pump and multistage pump can be divided into by structure；Boiler feed pump and dosing pump etc. can be divided into by purposes；Water pump, oil pump and slush pump etc. can be divided into by the character of conveying liquid.According to or without axle construction, straight line pump and conventional pump can be divided.
Pump in use needs to realize opening and closing under the effect of pump valve, tradition pump valve is in use, the active force relying on conveying thing is needed to make spool overcome acting force of the spring, realize spool to separate with valve seat, and then realize the unlatching of valve, the pump valve of this structure in use needs to carry thing and has certain pressure, therefore uses the pump valve of this structure to need extra supercharging equipment, thus will increase the complexity of whole system.
Utility model content
This utility model is intended to provide a kind of and need not to carry thing and have the highest pressure and can be achieved with normally-open pump valve.
Pump valve in this programme, including valve seat, guide post and the spool being positioned at valve seat top, guide post includes the first thread segment, cylindrical section and the second thread segment, and the first thread segment is connected with valve seat, and spool kink is at cylindrical section, centered by guide post, two inlet openings it are symmetrically arranged with on valve seat, it is provided with electromagnetic block at second thread segment, electromagnetic block offers draw-in groove, in draw-in groove, be provided with magnet exciting coil, on valve seat, also circumference is evenly equipped with at least two groove, is equipped with extension spring between each groove and spool.
The principle of this programme is: when pump valve needs to cut out, under the active force of groove and the extension spring of spool, spool fits tightly with valve seat, now pump valve is closed, when pump valve needs to open, conveying thing inlet opening from valve seat enters, it is energized in magnet exciting coil simultaneously, under the effect of magnet exciting coil, electromagnetic block will produce electromagnetic force, under the effect of this electromagnetic force, cylindrical section along guide post is moved by spool to electromagnetic block direction, now spool separates with valve seat, and pump valve is opened, and conveying thing is transmitted through pump valve.
The advantage of this programme is: in this programme, the unlatching of pump valve is dependent in the magnet exciting coil of electromagnetic block energising, electromagnetic block produces electromagnetic attracting force spool and lifts off a seat and realize, therefore this programme also can realize the normally-open of pump valve in the case of conveying thing pressure is the least, the whole pump structure thus using this programme pump valve is simple, and cost is relatively low.
Further, also include control circuit, control circuit is connected with external dc power, control circuit includes current-limiting resistance, the contact switch connected with current-limiting resistance and the magnet exciting coil in parallel with contact switch, contact switch is arranged on the spool side towards valve seat, when under the effect at conveying thing, when spool overcomes generation gap between the active force of extension spring and valve seat, contact switch disconnects, now external dc power is by by the magnet exciting coil in parallel with contact switch, magnet exciting coil is energized, electromagnetic block produces electromagnetic force, under the effect of this electromagnetic force, spool moves along cylindrical section to electromagnetic block direction, spool separates with valve seat, therefore this programme can realize automatically turning on of pump valve.
Further, control circuit also includes connecting with magnet exciting coil the diode in parallel with contact switch, and the anode of diode is connected with external dc power positive pole, owing to opening of diode needs certain cut-in voltage, therefore diode can improve the reliability of whole control circuit, prevents maloperation.
Further, the external diameter of cylindrical section is more than the external diameter of thread segment, and when electromagnetic block is arranged on thread segment, the installation site of electromagnetic block, more than the external diameter of thread segment, can be defined by the external diameter of cylindrical section.
