Abstract
The utility model discloses a simple water proportional valve for a gas water heater. The simple water proportional valve comprises a valve body and a valve core arranged in the valve body, wherein a water inlet channel and a water outlet channel are formed in the valve body. The simple water proportional valve is characterized in that the valve core comprises a rotor driven by a motor and a stator matched with the rotor; and a valve core hole communicated with the water inlet channel and the water outlet channel is formed in the rotor. The phenomenon that the conventional water proportional valve is blocked at high water inlet pressure is avoided, the torque required by rotation of the motor is reduced, the service life of the motor is prolonged, the process is simplified, the structure is optimized, and the cost is reduced.
Description
Technical field
The utility model relates to technical field of water heaters, relates to a kind of gas water-heater more specifically with simple and easy water Proportional valve.
Background technique
It is long-pending to the shutoff water flow section that gas water-heater water Proportional valve adopts spiral rising promotion poppet shaft at present, thereby cause the change of water flow, and there is the bigger defective of running torque in this structure, and the water Proportional valve does not have by function; It is stuck to descend the water Proportional valve to be prone to more greatly at intake pressure, complex manufacturing technology, and cost is higher.
The model utility content
The purpose of the utility model is exactly that provide for the deficiency that solves existing technology a kind of not only simplifies technology, optimizes structure, reduces cost, reduces motor rotation required torque; Prolong motor working life, and can solve present water Proportional valve at the gas water-heater of the stuck phenomenon of intake pressure under more greatly with simple and easy water Proportional valve.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of gas water heater is with simple and easy water Proportional valve; The spool that comprises valve body and interior setting thereof; Be provided with the water-in and water-out passage in the valve body; It is characterized in that said spool comprises that rotor is provided with the spool bore with the conducting of water-in and water-out passage by the rotor of driven by motor and the stator that cooperates with rotor.
As further specifying of such scheme, said rotor and stator be stack setting successively from top to bottom, and the bottom of stator is provided with sealing gasket.
Said rotor is provided with plural spool bore, and spool bore is an arc-shaped through-hole, and stator is provided with opening and said arc-shaped through-hole matches.
Said rotor end-face is provided with transmission shaft, and motor joins through gear train and transmission shaft.
Said valve body is a cascade tubular structure, and spool is arranged between the water-in and water-out passage, is provided with temp-sensitive apparatus and water flow sensing unit in the intake tunnel.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts stepper motor to drive rotor spool, and stepper motor transfers electrical signal to torque, and through gear train (deceleration increase turn round), transmission shaft rotor is passed in torque; Relatively rotate through rotor and stator and to reach the controlled water flow sectional area, utilize and regulate that water flow section amasss the controlled water flow amount or by current, cost declines to a great extent; Volume is little; Can eliminate water Proportional valve stuck phenomenon, reduce motor rotation required torque, prolong motor working life.

Embodiment
Like Fig. 1～shown in Figure 3; A kind of gas water heater of the utility model is with simple and easy water Proportional valve; The spool 2 that comprises valve body 1 and interior setting thereof is provided with water-in and water-out passage 3,4 in the valve body 1, valve body 1 is a cascade tubular structure; Spool 1 is arranged between the water-in and water-out passage, is provided with temp-sensitive apparatus 5 and water flow sensing unit 6 in the intake tunnel 3.Wherein, spool 2 comprises rotor 2-1 that is driven by motor 7 and the stator 2-2 that cooperates with rotor, and rotor 2-1 is provided with the spool bore 2-11 with the conducting of water-in and water-out passage.Rotor 2-1 and stator 2-2 be stack setting successively from top to bottom, and the bottom of stator 2-2 is provided with sealing gasket 2-3.In the present embodiment; Rotor 2-1 is cylindrical, and rotor is provided with plural spool bore 2-11, wherein; Spool bore is an arc-shaped through-hole; Stator is provided with opening, and this openings of sizes and said arc-shaped through-hole match, and realizes opening of arc-shaped through-hole or closed through relatively rotating of stator 2-2 and rotor 2-1.Rotor end-face is provided with transmission shaft 2-12, and motor 7 joins through gear train 8 and transmission shaft.
In the using process; Water flow sensor detects water-flow signal; Stepper motor transfers electrical signal to torque; And rotor is passed in torque through gear train (deceleration increase turn round), transmission shaft, and relatively rotate through rotor and stator and reach the controlled water flow sectional area, utilize and regulate that water flow section amasss the controlled water flow amount or by current.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
