われている。2. Description of the Related Art Conventionally, in a cold region, water has been drained from a pipe using an antifreeze water tap or a drain valve to prevent freezing. However, freezing accidents due to forgetting to operate have not stopped, and in recent years, water temperature or atmospheric temperature has been measured with a sensor, and when approaching the freezing temperature, the motor is automatically rotated to move the valve, and antifreeze A so-called automatic draining device with a sensor, which operates a water tap or a drain valve to drain water, has begun to be used. In the above case, in order to drain the water, air must be introduced into the pipe using a faucet, etc.In order to eliminate the irrationality that requires manual operation, install an air supply valve near the faucet, etc. When the apparatus is in a drainage state, a method of discharging air in a pipe and a faucet by sucking air from the air supply valve is generally performed.

う。[0003] However, for example, the shape is complicated, such as a hot and cold water mixing tap, and due to its structure, water always remains in the valve portion.
To prevent this, a water drain valve should be provided at the bottom of the hot water mixer tap, which should be opened to drain the pool water from the valve.In cold regions, many hot water mixer taps have a water drain valve. Although it is used, it is meaningless to use an automatic water draining device with a sensor if water is drained manually.

A valve box having an upwardly facing valve seat at an intermediate portion, a drain port at a lower end, a valve lid connected to an upper end of the valve box and having a water inlet and a mounting screw at an upper portion, and seated on the valve seat to stop water. And a shape memory spring made of a shape memory alloy having a transformation point slightly higher than 0 ° C., which is locked to the valve lid and applies a downward pressing force to the valve body. A bias spring that is stopped and applies an upward pressing force to the valve body.The spring is such that when the water temperature is high, the shape memory spring presses the valve body against the valve seat over the force of the bias spring, and the water temperature is reduced. 0
When the temperature drops to around ℃, the force is reversed and the valve body is detached upward from the valve seat.

与えるバイアスばねである。FIG. 1 shows an embodiment of the present invention. Reference numeral 1 denotes a valve box, which is provided with a valve seat 2 at an intermediate portion and a drain port 3 at a lower end. The valve wall 4 is formed. 5 is the valve box 1
The valve lid is connected to the upper end of the water heater, and has a fitting 6 and a water inlet 7 which are connected to the above-mentioned hot water mixer tap or the like. 8
Is a valve body which moves up and down by using the valve wall 3 as a guide. A dovetail groove 9 is formed in the lower part, and a packing 10 for sealing the valve seat 2 is mounted so as not to be detached. Reference numeral 11 denotes a shape memory spring made of a shape memory alloy that is locked to the valve lid 5 and applies a downward force to the valve element 8, and 12 is a bias spring that is locked to the valve box 1 and applies an upward force to the valve element 8. is there.

ことになる。In this embodiment, in addition to the above-mentioned force, the valve body 8
, The water pressure is acting downward, so that during normal water flow, the valve body 8 is still seated on the valve seat 2 even when the temperature falls below the transformation point even when the temperature falls below the transformation point. However, when the antifreeze hydrant is drained and the above water pressure disappears, the valve body 8 is raised by the bias spring 12 if the water temperature is below the transformation point, and the water from the water inlet 7 is discharged. Valve wall 4
Then, the water is discharged from the drain port 3 through the gap 13 of the valve body 8, and if the water temperature is higher than the transformation point, no water is discharged.

Also, instead of mounting the packing 10 on the valve body 8, the packing 1 is mounted on the valve box 1 side.
0 may be used as the valve seat 2. For convenience of explanation, the case where the present school plan is mounted in the vertical direction has been described. However, the school plan may be mounted in the horizontal direction. It is also possible. At that time, the drain port 3 becomes an intake port.

Therefore, when using an automatic drainage device with a sensor, it is only necessary to replace the drainage valve with a hot / water mixer tap. When draining using a normal antifreeze water tap or drain valve, in addition to the effect of completely draining the water without any operation and preventing damage to the hot and cold mixing tap due to freezing. In addition, it can also be attached to the fittings of the pipe, even if it is used as a drain valve or when it is used as an intake valve, even if the antifreeze hydrant etc. is drained, it must be near the freezing temperature Since water does not escape, there is also an effect that there is no need to discard useless water and the system is economical.
