Claims

[Scope of utility model registration request]

The electric drive mechanism 14 is screwed together with the male thread 24' formed on the outer periphery of the propulsion shaft 24 and the female thread 23.
This is an electric valve that converts the rotation of a rotor 17 into linear motion, and the main body 25 has an upper part connected to the electric drive mechanism 14 and the main body 27 has inlet and outlet pipes 34, 35, and 36. A chamber 126, a chamber 337, a chamber 239, and a chamber 441 are formed in the center of the main body 25 and the main body 27 in order from above, and the valve seat 38 at the lower end of the chamber 337 and the valve at the upper end of the chamber 441 The inner diameter of the seat 40 is φd
1, and on the other hand, in the chambers 1 to 4, there is a pressure equalizing section 2 formed above with the same diameter φd2 as the diameter φd1.
9, an upper valve element 32 in the intermediate portion, and a lower valve element 33 fixed downward by an appropriate means, and the valve element 28 is configured to be vertically slidable, and the valve shaft 49 is inserted into the hole 31 in the center of the valve element 28. It is arranged so that vertical movement of the valve stem is transmitted to the valve body 28, and no vertical force acts on the valve body 28 even if fluid flows from any of the inlet and outlet pipes 34, 35, and 36. The structure of the electric three-way valve is characterized by the following.
