Description
Technical field
The utility model relates to flow-limiting valve, is specifically related to water heater flow-limiting valve.
Background technique
What require life living environment along with people improves constantly, and water heater is widely used in occasions such as family, apartment, hotels.The water-outlet quantity of most common water heater will manual tune artificially, and usually occurs that winter water is not warm, the overheated situation of water in summer.When seasonal variations in summer in winter, need manual switchover water yield switch.Even if some water heater can control water-outlet quantity, this also depends on high cost and the electron controls technology of complexity realizes, and considerably increases the design cost of production of water heater.Therefore, current most widely used general and that cost is minimum water flow control mode realizes by traditional memory alloy spring, constant temp gas water heater, but because the regulation range limiting existing memory alloy spring power difference ratio at different temperatures by technique is less, can not meet technical requirements, water termostat cannot be realized out at low temperatures.
As can be seen here, there is the problem that regulation range is little, can not ensure out water termostat in current Water flow control valve.
Model utility content
Technical problem to be solved in the utility model is the problem that current Water flow control valve exists that regulation range is little, can not ensure out water termostat.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts there is provided a kind of water heater flow-limiting valve, comprise body, the two ends of described body are provided with water intake and water outlet, described water outlet towards with described water intake vertically, it is characterized in that, in described body, be provided with Flow-rate adjustment assembly, be provided with the first boss and the second boss in described body, described Flow-rate adjustment assembly comprises:
Joint, is fixed on the inwall of described water outlet, be resisted against on described first boss, and its center is provided with rotatable adjusting screw rod, described inner nosepiece wall is also provided with collar and gland inside it,
Spool, one end is affiliated on described collar, and the other end is resisted against on described second boss, and be provided with memory spring outside it, described memory spring is resisted against between the outer side surface of described spool and described gland, and the water inlet of described adjusting screw rod and described spool is oppositely arranged
Opposite force spring, two ends are resisted against on the side of described spool and the inwall of body respectively.
In above-mentioned water heater flow-limiting valve, the center of described joint is provided with screwed pipe, and described screwed pipe is connected by supporting bar with the periphery of described joint, described adjusting screw rod and described screwed pipe adaptation.
In above-mentioned water heater flow-limiting valve, the inwall of described joint is provided with the first ladder and the second ladder, and described collar, described gland are separately positioned on described first ladder, described second ladder.
In above-mentioned water heater flow-limiting valve, one end of described spool stretches out and is provided with mounting part, and the other end is provided with circumference boss, and described mounting part is affiliated on described collar, and described memory spring is resisted against between described circumference boss and described gland.
The utility model, opposite force spring is added between spool and body, jointly the movement of spool and position are adjusted with memory spring, because opposite force spring is contrary with the elastic force of memory spring, like this by arranging length and the elastic force of spring, just can increase regulation range and the precision of dynamics, therefore with regard to the position of energy precision control valve core, thus control water flow, the error of the temperature of water outlet of water heater is remained on more among a small circle, structure is simple, and cost is low.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
The utility model provides a kind of water heater flow-limiting valve, adds opposite force spring, and the error of the temperature of water outlet of water heater is remained on more among a small circle, and structure is simple, and cost is low.Below in conjunction with specific embodiment and Figure of description, the utility model is described in detail.
As shown in Figure 1, the water heater flow-limiting valve that the utility model provides comprises body, the two ends of body are provided with water intake 1 and water outlet 9, water outlet 9 towards with water intake 1 vertically, water flow sensing unit is provided with in body, water flow sensing unit comprises scroll 2, magnet rotor 31 and Hall subassembly 32, for recording the water flow of process in body.
Be provided with Flow-rate adjustment assembly in body, be provided with the first boss 11 and the second boss 12 in body, Flow-rate adjustment assembly comprises: joint 7, spool 5 and opposite force spring 41.
Joint 7 is fixed on the inwall of water outlet 9, and inner side is resisted against on the first boss 11, and its center is provided with rotatable adjusting screw rod 8, in the present embodiment, the center of joint 7 is provided with screwed pipe, and screwed pipe is connected by supporting bar with the periphery of joint 7, and adjusting screw rod 8 is adaptive with screwed pipe.Joint 7 inwall is also provided with collar 62 and gland 61, in the present embodiment, the inwall of joint 7 is provided with the first ladder and the second ladder, and collar 62, gland 61 are separately positioned on the first ladder, the second ladder.O type circle 71 is provided with between the outer side surface of joint 7 and body.
One end of spool 5 is affiliated on collar 62, and the other end is resisted against on the second boss 12, and is provided with memory spring 51 outside it, and memory spring 51 is resisted against between the outer side surface of spool 5 and gland 61, and adjusting screw rod 8 is oppositely arranged with the water inlet of spool 5.In the present embodiment, one end of spool 5 stretches out and is provided with mounting part, and the other end is provided with circumference boss, and mounting part is affiliated on collar 62, and memory spring 51 is resisted against between circumference boss and gland 61.
The two ends of opposite force spring 41 are resisted against on the inwall of spool 5 away from the side of memory spring 51, body respectively.
Working principle of the present utility model is as follows: when the current of different temperatures flow through memory spring 51, there is corresponding change in the elasticity of memory spring 51, memory spring 51 produces axial length change under the change of temperature, and then the distance between the water inlet of spool 5 and adjusting screw rod 8 is changed, thus the flow of adjustment current.The characteristic of memory alloy spring is exactly, and when entering water temp height, memory alloy elastic increases.When entering water temp is low, memory alloy spring elasticity reduces.
The utility model, opposite force spring is added between spool and body, jointly the movement of spool and position are adjusted with memory spring, because opposite force spring is contrary with the elastic force of memory spring, like this by arranging length and the elastic force of two springs, just can increase regulation range and the precision of dynamics, therefore with regard to the position of energy precision control valve core, thus control water flow, make water outlet of water heater constant temperature.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change made under enlightenment of the present utility model, and every have identical or close technological scheme with the utility model, all falls within protection domain of the present utility model.
