Abstract

PURPOSE:To make it possible to supply hot or cold water at a prescribed temperature as well as freely incorporate the whole valve into the plug housing of a hot and cold water mixing plug by automatically adjusting the mixing ratio of hot water to cold water by utilizing a shape storing alloy. CONSTITUTION:When a valve body 4 is located on a position where the hot water inlet (a) of a housing 2 is opened, and the cold water inlet (b) closed, hot water firstly flows from the hot water inlet (a) into a mixing chamber (r) to permit the temperature of the water to rise from the prescribed temperature, so that shape restoring force is apllied besides the inherent expansion force to the coil 7 of a shape storing alloy which stretches against the spring force of a bias spring 5. And, as soon as the opening of the hot water inlet (a) is reduced, the valve of the cold water inlet (b) is opened, allowing the water temperature within the chamber to be reduced. As the water temperarure reduced, a cork 7 shrinks in the reverse way and the valve body 4 is pushed back in the opposite direction with the spring force of a return spring 8, allowing the opening of the cold water inlet (b) to be reduced. Thus, it is possible to always obtain hot or cold water, at a prescribed temperature with the repetition of these series of right and left movement of the valve body 4.

伸長する。To describe the operating principle of the pulp of the present invention with regard to the structure KiI on the ridges, let us assume that the hot water port (a) of the housing 2 is opened and the cold water port (mk is closed) as shown in the valve body 4 or the first glIC. When h is assumed, the hot water first flows into the mixing chamber needle field circle from the hot water port (a), and the temperature of the hot water Ii rises above a constant temperature, so the 8M1 coil 7rr- has a unique expansion force as well as a shape The restoring force acts, and it expands against the spring force of the bias spring 5.

る。At this time, the proximal end of the valve stem 3 is held in the adjustment 11 by the overspring holder 91, so the l1Mm coil 7 is supported at one end of the saddle 690 at the end of the valve stem and moves in the direction of the arrow in the figure. As the opening amount of the hot water port (a) decreases, the cold water port (14) also opens and the temperature of the hot water in the room decreases. As the temperature decreases, the 8Mm coil 1 begins to contract, and the valve body 4 is pushed back in the opposite direction by the spring force of the return spring 8. By repeating these series of left and right movements Wb of the valve body 4, the 8 mm coil 1 and the other springs are brought into equilibrium, and the temperature of the cold and heat is always constant. It yields 4 tons of warm water.

'1'' and move the alignment adjustment 11 to the left, a gap will be created between the gk joint between the overspring holder 9' and the adjustment 11, so you can keep it there. The balance with coil 1 is lost,
Due to the stretching force of the 8MM coil 7, the saddle 6 is moved along with the valve stem 3r.
At the same time, move the bias coil 5s hole i-5' to the left to restore the balance of the 8M coil 1. At this time, the holder 5', the valve body 4 and the
The turn spring 8 is extended by a gap amount of π generated at the valve body, and the valve body 41r is pushed to the left, thereby increasing the opening amount of the hot water port (a).

By moving the adjuster 11 to the right with the tJ operation, the valve stem 3 moves to the right via the overspring holder 9'r, so that the valve stem 3 is pressurized by the saddle 6.
Mm coil or valve body 4r against the spring force of return spring 8? IFlIL, as a result, the opening amount of the cold water port (b) increases and hot water at a low temperature is obtained.

However, since the overspring 9 applies an appropriate bias pressure load to the return spring 8 in advance, even after the valve body 4 is pressed against the upper valve [rLπ], an excessive load is applied to the first valve body 4. Adjustment member) 11'91- can be moved to the right without applying any pressing force,
It prevents 1Iv and π.

Since it has the function of making it possible for the m coil T to start elongating by M'% at a predetermined temperature i, the bias spring 5 is set at the +ms nut 13 in the middle of the valve stem for the 8 mm coil 1, which starts elongating at a humidity lower than the set humidity. For those that stretch at high temperatures, use one that is adjusted in advance to make the pie scar stronger and to apply a weaker pie scar.

Adjust the summer hysteresis, adjust the hot water temperature to the same level as above, and change the temperature during hot water supply or operate the knob.
In addition, since there are 9P seats on both the hot water outlet and the cold water outlet, the hot water or cold water can be stopped or stopped, and the Iif range of the discharged water can be expanded. Since it is a cartridge type and is a To4, the trouble of making and installing it can be greatly reduced. It has excellent characteristics such as easy inspection.
