Abstract
The utility model provides a memory alloy anti-scald valve, comprising a valve body, a valve piston, a valve cover, a memory alloy spring, a back spring, a regulating screw pad, etc. The left chamber of the valve body is provided with the regulating screw pad and the back spring, and the right valve chamber is provided with the memory alloy spring. The valve is ensured to be closed when the temperature is more than 45 DEG C (+/-)2 DEG C through the memory alloy spring and the back spring system having precise design, and the sanitary bathing person is prevented from being scalded; the memory alloy spring can adopt nickel-titanium, nickel-titanium copper, or copper-aluminum-beryllium X alloy, and the memory alloy spring can be a coil spring and also can be a disk spring. The memory alloy anti-scald valve has the characteristics of reliable working, simple structure, convenient use, low price, etc. and can ensure the sanitary bathing safety of children.
Description
(1) technical field
The utility model belongs to medium temperature internally piloted valve field.Control maximum water temperature during bathroom, water-exit temperature is the highest generally to be no more than 45 ℃ ± 2 ℃, prevents to scald the bathroom personnel.The utility model is applicable to shower, bath in a tub and washing, is specially adapted to child and uses.
(2) background technique
When using common bathroom valve bathroom, scald dead accident and happen occasionally, especially for children.The present domestic anti-scald valve that there is no, the anti-scald valve of more memoryless alloy functional material control, too complicated He Ang is expensive for external anti-scald valve.
(3) summary of the invention
The purpose of this utility model provides a kind of anti-scald valve of memory alloy spring control.By the temperature-sensitive effect of memory alloy spring, cooperate the coordination of back of the body spring, when the mixing water temperature surpasses 45 ℃ ± 2 ℃, cut off automatically and supply water, prevent the scald personnel, when being lower than 45 ℃ ± 2 ℃, valve opening supplies water.
The utility model is made up of valve body, valve gap, valve plug, memory alloy spring, back of the body spring, adjusting spiral shell pad etc.When temperature was lower than 45 ℃ ± 2 ℃, back of the body spring force was opened valve, the supplying mixed Heshui all the time greater than the memory alloy spring; When mixing water temperature during greater than 45 ℃ ± 2 ℃, the memory alloy spring force is greater than back of the body spring, and throttle down, and stop supplies water prevents that high-temperature water from scalding personnel.The mixing water temperature is higher, and the power of closing is bigger, further reliably throttle down.The memory alloy spring of design and back of the body spring interaction systems calculate and test its reliable operation through accurate.The memory alloy spring adopts NiTi, NiTi copper or copper-aluminium and beryllium X-alloy, and the memory alloy spring can be a helical spring, also can be the butterfly spring.
(4) description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, can be described as follows its function:
When the mixing water temperature surpasses 45 ℃ ± 2 ℃.Memory alloy spring 5 stretches automatically, overcomes back of the body pressure of spring 6 and mechanical friction and promotes valve plug 3 left lateral, by the valve cone face on valve plug 3 left sides and the valve seat throttle down on the valve body 4, stops media flow; When the mixing water temperature is lower than 45 ℃ ± 2 ℃, memory alloy spring 5 softnesses, back of the body spring 6 is enough to overcome the elastic force of memory alloy spring 5, make valve plug 3 right laterals, open valve, adjusting spiral shell pad 2 in the valve gap 1 in the right valve chamber can be adjusted the closing temperature of control in order to regulate back of the body spring pressure, and valve is in closed condition when guaranteeing that water temperature is higher than 45 ℃ ± 2 ℃.
The utility model is desirable bathroom anti-scald valve, especially protects the desirable anti-scald valve of child's bathroom safety.
(5) embodiment
The utility model is machined into valve body, valve gap, valve plug and adjusting spiral shell pad with the ABS raw material; With the hot coiled memory alloy of Ultimum Ti spring, with the cold coiled back of the body of Stainless Steel Wire spring; Totally 20 of assemblings, the back hands over the user to use after tested, proves with shower to install easily, and is easy to use, reliable operation, valve closing when guaranteeing 45 ℃ ± 2 ℃, the anti-scald effect is obvious.
Claims (2)
1. a bathroom is made up of valve body, valve plug, valve gap, memory alloy spring, back of the body spring, adjusting spiral shell pad etc. with the anti-scald valve, it is characterized in that being equipped with in the left valve chamber back of the body spring, and the memory alloy spring is housed in the right valve chamber, and anti-scald bathroom temperature is 45 ℃ ± 2 ℃;
2. require described anti-scald valve as right 1, it is characterized in that the memory alloy spring adopts NiTi, NiTi copper or copper-aluminium and beryllium X-alloy, the memory alloy spring can be a helical spring, also can be the butterfly spring.
