Abstract
The utility model relates to a water heating facility. A safety valve comprises a valve body and a valve core. The safety valve is characterized in that a shape memory alloy spring is fixed on the valve core. When water temperature reaches certain set temperature, the spring can rapidly respond along with the changes of the water temperature, the spring can drive the valve core to close the valve, and water flow can be cut off; when the water temperature drops below the set temperature, the spring can be contracted to drive the valve core to be disengaged, and the water flow can be unblocked again. The safety valve which is installed on the water pipe of a spray head for shower can guarantee that people under shower can not be scalded. The safety valve has the advantages of simple structure, low cost, reliable action, easy fabrication, etc., and is suitable for industrial production.
Description
The utility model relates to hot water facility.
In the prior art, the water-exit temperature of shower nozzle is by manually regulating voluntarily, owing to come coolant-temperature gage and flow and non-constant in the hot-water line; low rapid change when high in the time of usually can occurring; therefore tend to take place the scald situation, especially, more have no a sense of safety children and handicapped old man.
The purpose of this utility model is to provide a kind of hot water safety valve, and it can control water-exit temperature below limiting temperature automatically.
The purpose of this utility model is realized by following mode.
Described safety valve includes valve body and valve stamen, it is characterized in that being fixed with shape memory alloy spring on the described valve stamen, and the other end of this spring is fixed on the valve body.When the water temperature that flows through is higher than certain setting temperature, shape memory alloy spring generation deformation, spring extends automatically, and when reaching limiting temperature, it forces the valve stamen tightly to seal valve, thereby cuts off flowing water.This valve is installed on the water pipe that connects shower nozzle, can guarantee that the shower people is not scalded.When the shower people regulates when water temperature being dropped to be lower than limiting temperature, this spring shrinks, and valve stamen and valve are thrown off, and current are unimpeded again.
Accompanying drawing below in conjunction with embodiment is further described.
Fig. 1 is described embodiment's a structural representation.Among the figure, 1 is valve cylinder, and 2 is the valve stamen, and 3 is spring, the 4th, adjust circle, and the 5th, Cock screw, 6 is seal ring, the 7th, at the bottom of the valve.
In the present embodiment, valve body is adjusted circle 4 usefulness and is threaded on the valve cylinder 1 by cylindrical valve cylinder 1 with 7 constituting at the bottom of the all-in-one-piece valve that is threaded, and seal ring is arranged between at the bottom of valve cylinder and the valve, one end of extension spring 3 is enclosed within the shoulder hole of adjusting circle 4, and is fixing by Cock screw 5 simultaneously.The other end of spring 3 puts in the blind hole at valve stamen 2 backs, also has Cock screw 5 fixing.Described spring is a copper-based shape memory alloy stretching spring, spring diameter D=14mm, brass wire diameter d
1=3mm, number of active coils n=6, valve port diameter D
1=12.7mm, this spring begin to take place deformation in the time of 35 ℃, when to 45 ℃ ± 2 ℃, spring elongation makes the valve stamen seal valve, and then spring shrinks when 45 °＞T of temperature＞35 °, makes valve open.
The hot water safety valve that the utility model provides uses memory alloy spring as thermosensitive element, it can change to occur fast responding with coolant-temperature gage moves, driving the valve stamen opens or closure valve, thereby limit coolant-temperature gage automatically, and this valve has characteristics such as simple in structure, with low cost, easy to process, is suitable for industrialized production.
Claims (1)
1, a kind of hot water safety valve, it includes valve body and valve stamen, it is characterized in that being fixed with shape memory alloy spring 3 on the described valve stamen, and the other end of this spring 3 is connected on the valve body.
