Problems solved by technology
[0003] The coil fixing frame 15 used for the fixed connection between the valve body 12 and the coil 11 of the electric valve is a stamped sheet with a certain thickness. Excessive resistance, on the one hand, increases the difficulty of installation, on the other hand, during the installation process, it may also cause distortion and deformation of the pipe of the connection assembly welded on the valve body 12, resulting in the loss of fluids such as refrigerant

Embodiment Construction
[0044] The main idea of the present invention is to provide a fixed connection device for a valve body and a coil of an electric valve and the electric valve. Wherein, the valve body and the coil of the electric valve are fixedly connected to the positioning card through the fixing frame, and the fixing frame has a concave hole or a groove, which is used to fasten and connect with the convex point on the positioning card, and a guiding surface is also formed on the fixing frame, When the convex point on the positioning card climbs up the first surface of the fixing frame, the climbing resistance is reduced, and the above-mentioned concave hole or groove is opened on the first surface. The structure of the guide surface can reduce the resistance of the fixed connection device between the valve body and the coil during installation in a relatively simple way without increasing the manufacturing cost of the electric valve and without increasing the installation difficulty of the...

The invention discloses a fixed connection device for a valve body and a coil of an electric valve and the electric valve. The valve body and the coil of the electric valve are fixedly connected with each other through a fixing frame and a positioning clamping sheet; the fixing frame is provided with a concave hole or a concave groove to be connected with a bump on the positioning clamping sheet by buckling; a guide surface is also formed on the fixing frame; when the bump on the positioning clamping sheet climbs on a first surface of the fixing frame, climbing resistance is reduced; and the first surface is provided with the concave hole or the concave groove. In the invention, the resistance for the bump of the positioning clamping sheet to climb on the fixing frame can be reduced, so that mounting difficulty of the coil and the valve body is reduced; and distortion of a connecting pipe in a connecting pipe assembly is avoided to prevent pressure of fluid or loss of energy.
Description
technical field [0001] The invention relates to electric valve technology, in particular to a fixed connection device for a valve body and a coil of an electric valve and an electric valve, belonging to the technical field of electric valves. Background technique [0002] figure 1 It is a simple structural schematic diagram of an electric valve in the prior art. Such as figure 1 As shown, the electric valve is composed of a coil 11 and a valve body 12. An intermittent pulse current is applied to the coil 11 to generate alternating magnetic poles on the tooth poles in the coil 11, thereby driving the permanent magnetic rotor in the valve body to rotate. The external thread of the screw rod cooperates with the internal thread of the transmission nut pressed on the valve seat, which is converted into the up and down movement of the valve needle to control the opening of the valve port, so as to realize the connection from the first connecting pipe 13 to the second connecting ...
