Claims

[Scope of utility model registration request]

The valve shaft 13 formed in the fitting part 13a, the male thread 13b, the shaft part 13c, and the male thread 13d at the lower end is rotated from above by an electric drive mechanism, and this rotation is converted into linear rotational motion by a propulsion bearing 14 having a female thread. A main body 16, which is an electric valve to be converted, whose upper part is connected to an electric drive mechanism 15, and a main body 19 having inlet and outlet pipes 17 and 18 are connected by appropriate means via a seal guide 20, and the main body 1
6 and the chambers 1 and 21 are formed in the center of the main body 19, and the inner diameter of the valve seat 22 at the lower end of the main body 19 is set to φd.
₁ , and a valve body 23 which is vertically slidable and has a pressure equalizing portion 23a with a diameter φd ₂ is installed in the chambers 1 and 21, and an outer circumferential ring 24a of a bearing 24 is installed in the hole of the valve body 23. is fixed by a fixing screw 25, and the inner surface of the inner circumferential ring 24b is fixed to the shaft 13c at the lower end of the valve shaft 13 by a lower adjustment screw 26 and an upper biasing means 27, and the inner diameter of the valve seat 22 is φd _1. and the diameter _φd2 of the valve body pressure equalizing portion 23a are formed to have the same diameter, so that no vertical force is applied to the valve body 23 even if the refrigerant flows in from either of the refrigerant ports 17 and 18. Characteristic electric valve structure.
