Claims (1)

[Scope of utility model registration request] A connection that allows the ends of each circuit pipe that constitutes a high and low pressure circuit to be tightly connected to the valve cavity 2 that opens on both longitudinal end surfaces of the valve body 1 through a set distance from the outer circumferential body. Each of the three ports 3, 4, and 5 is penetrated, and one of the openings of the valve cavity 2 is made into a valve operation port 7, so that a cap 9 can be tightly fitted around the outer periphery of the valve operation port 7, and the other opening is made to be a high-pressure valve. A small-diameter valve seat 26 is provided inside the connection port 6, and a position adjacent to the inside of the small-diameter valve seat 26 is the opening of the connection port 5, and the opening of the connection port 5 is abutting against the small-diameter valve seat 26. It has a valve head 12 at one end that acts to close the valve, and
A central valve rod 10 having a wrench hole 13 on the opposite end surface and further provided with a male screw 15 in the middle that can be screwed into a female screw 18 provided on the tubular valve body 11;
The central valve rod 1 is attached to the internal thread 18 provided on the inner periphery of the central valve rod hole 17 of the tubular valve body 11, which has a hexagonal wrench hole 16 at one end and has a much shorter overall length than the total length of the central valve rod 1.
0 are screwed together to combine, and the male screw 21 provided on the outer periphery of the tubular valve body 11 is screwed to the female screw 27 provided in the large diameter valve chamber 22 of the valve cavity 2 to combine. A valve seat 23 is provided at the lower end of the large diameter valve chamber 22, and the tapered valve portion 19 provided on the outer periphery of the lower end of the tubular valve body 11 comes into contact with the valve seat 23 to perform a valve action.
The connection port 3 is opened in a part of the large diameter valve chamber 22 that is close to the valve seat 23, the connection port 4 is opened in a low pressure medium passage 24 that forms the valve opening of the valve seat 23, and The small diameter valve chamber 25, which is connected to allow the valve body of the central valve rod 10 to closely slide, is connected to the small diameter valve seat 2.
Refrigerant 2 for an air conditioner, in which a stop ring 29 is fitted between the outer periphery of the end of the tubular valve element 11 and the inner periphery of the opening of the valve operation port 7 to prevent the inserted tubular valve element 11 from slipping off. Open/close valve for circuit.
