Abstract
The utility model belongs to the electric ball valves, in particular to a low energy-cost mini electric ball valve used for an IC card cold-hot water meter. An elastic seal ring is respectively arranged between a seal ring and a valve seat or between valve plugs at two sides of the valve balls. A shaft gear of a valve rod is fixed with a rotary disk which presents a cam shape. Two flanges with steep cuts are symmetrically arranged on the rotary disk. Two reed switches are glidingly connected with the flanges and the cuts. A mutual position between contacts of the two reed switches correspond to a 90-degree turning angle of four opening and closing positioning positions with the same revolving direction of the valve balls. One end of the two reed switches is connected with an input end of the same power supply of a motor. The other end of the two reed switches is respectively connected with an anode end of own power supply. The utility model solves the problems of the existing electric ball valve that a rotary torque of the valve ball is contrary to a seal; the positioning of valve opening and closing is not so accurate. The utility model has the distinct advantages that the rotary torque of the valve ball is small; the sealing effect is reliable and the positioning of the valve opening and closing is accurate.
Description
Technical field
The utility model belongs to electric ball valve, particularly relates to the low-power consumption micro electric ball valve that the cold and hot water meter of a kind of suitable IC-card uses.
Background technique
The matching used electric ball valve of the cold and hot water meter of known IC-card is made up of the reduction gear driving mechanism between ball valve, motor and control circuit board thereof, motor and the stem shaft gear.Practice shows known electric ball valve because the conspicuous contradiction between the moment of rotation that ubiquity valve ball and the sealing, and ball valve opens and closes to locate and owes accurately outstanding problem and influence its extensive use.The basic reason that the problems referred to above occur is: known ball valve body is by valve seat and the valve that is threaded with the one end is stifled constitutes, the valve ball both sides are provided with respectively and block up the wear-resistant seal ring that engages with valve seat or valve, and its sealing effect often depends on the stifled degree that compresses of the valve that is threaded.Bigger for guaranteeing that sealing effect will cause valve ball to rotate required moment, cause the driving valve ball that motor and retarder can not flexibility and reliability to rotate, reveal otherwise cause the valve ball sealing part to produce again easily.In addition, known electric ball valve opens and closes the inaccurate drawback in location, is because inevitably come and go gap and error that the suitable contrary bi-directional drive of its gear drive exists superpose.
Summary of the invention
The utility model is owed technical problem accurately for the valve ball moment of rotation size that solves existing electric ball valve and exist and the contradiction between the sealing effect and valve opening and closing location, and a kind of valve ball moment of rotation is little, sealing is reliable and the low-power consumption micro electric ball valve of valve opening and closing accurate positioning and provide.
The utility model is that the technological scheme that the above-mentioned technical problem of the existing electric ball valve existence of solution is taked is: be respectively equipped with elastic seal ring between the seal ring of valve ball both sides and valve seat or valve are stifled; The shaftgear of valve rod is fixed with the rotating disk of cam-like, this rotating disk is symmetrical arranged two flanges with steep limit otch, two incision sites and the position, angle of valve ball are that 180 ° two open or to close the position location corresponding, be fixed in two reed witches and the flange and the otch slip joint of gearcase, mutual alignment between its contact of two reed witches is corresponding with four 90 ° of rotational angle that open and close the position location of the equidirectional rotation of valve ball, one end of two reed witches and the same power input of motor join, the other end of two reed witches respectively with power supply separately+extremely join.
The utility model can also be taked following technical measures:
The elastic seal ring that is provided with respectively between described valve ball both sides sealing ring and valve seat or valve are stifled is an O shape rubber seal.
Described valve stem casing is equipped with pressure ring, and its two ends are respectively equipped with the valve stem packing ring that engages with valve seat or gearcase.
The beneficial effects of the utility model and advantage are: the elastic seal ring that the exterior edge face of the seal ring at valve ball two ends is set, make seal ring have the ability of dynamic following valve ball according to its elasticity, make the sealing effect of valve ball obtain the essence improvement, and do not rely on the stifled degree that compresses of valve, therefore the required moment of rotation of valve ball is less, can satisfy micro motor and retarder flexibility and reliability and drive the needs that valve ball rotates.Alternately two reed witches of break-make and independently two DC electrical source make the valve ball of this electric ball valve open and close the sense of rotation unanimity, round gap and the error stack of having avoided the reduction gear driving mechanism to exist on the one hand along contrary bi-directional drive, on the other hand when valve ball is in the mechanical location of locating complete opening or closing, the corresponding DC electrical source of reed witch turned off in synchronization, avoided the mismatch error of control command and actuator, thus this electric ball valve to open and close the location very accurate.The utlity model has the outstanding advantage of low power consumption and reliable sealing, not only can be matched in the IC-card water meter, also can be used for air conditioner refrigerating, fields such as environmental protection water treatment and household electric appliance.
