Claims

[Scope of utility model registration request]

The valve body 1 opens at the base end 2 of the cylindrical valve body 1.
In the valve cavity 3 bored in the longitudinal direction, a stepped part that reduces the diameter of the cavity at a position close to the tip is used as a valve seat 4, and from the valve seat 4, the valve seat 4 communicates with the outer periphery from the tip. While opening the primary connection port 5 of
A secondary side connection port 6 communicating with the outer periphery is opened at a position adjacent to the valve seat 4 in the proximal direction to form a low pressure passage 8, and a passage opened at the tip and communicated with the low pressure passage 8. The valve core 9 is fitted to form a refrigerant charge port 10, and a female screw 13 is formed at a predetermined distance from the valve seat 4 toward the base end, and a female screw 13 is provided near the valve seat 4. A secondary side connection port 12 for high-pressure refrigerant and a secondary side connection port 11 are opened on the inner periphery at a distance set from the secondary side connection port 12 so as to penetrate through the outer periphery. In addition, it has a valve head 16 at its tip that can close the valve port when it engages with the valve seat 4, and the front portion including this valve head 16 opens and closes the opening of the secondary side connection port 6. A male male screw 18 is provided at a position where it can be screwed into the female female screw 13, and an annular groove 19 is provided on the outer periphery of the male male screw 18 in the distal direction. A valve rod 15 with an O-ring 20 fitted to the outer periphery of the position and the outer circumference of the position close to the base end is inserted into the valve cavity 3 of the valve body 1, and the stop ring 14 is fitted near the opening of the base end 2. An on-off valve for two refrigerant circuits of an air conditioner, characterized in that the valve rod 15 is enclosed.
