Embodiment Construction

[0029] Such as figure 1 shown, combined with Figure 2-6 As shown, the high-pressure two-way switching electric globe valve of the present invention includes a valve body 45, and the valve body 45 is provided with a normally open valve, a normally closed valve and a pilot valve, and the valve body 45 is provided with an air inlet 18, a normally The air supply port 23 on the open side and the air supply port 13 on the normally closed side. The normally open valve is provided on the normally open side of the valve body 45 , and the normally closed valve is provided on the normally closed side of the valve body 45 . Gas enters the valve body 45 from the air inlet 18, and then exits the valve body 45 from the normally open side gas supply port 23 / normally closed side gas supply port 13 for gas supply. Bidirectional switching refers to switching the gas supply between the normally open side gas supply port 23 and the normally closed side gas supply port 13 .

Abstract

The invention discloses a high-pressure two-way switching electric stop valve. The high-pressure two-way switching electric stop valve comprises a valve body, and the valve body is provided with a normally open valve, a normally closed valve, a pilot valve, a gas inlet, a normally open side gas supply port and a normally closed side gas supply port. The high-pressure two-way switching electric stop valve is applied to a ground gas supply system and a low-temperature filling system of a carrying model, is used for controlling a connector and a filling valve, achieves the purpose of two-way switching of a gas circuit, and has extremely high flexibility and reliability.

Description

technical field [0001] The invention relates to a valve, in particular to an electric cut-off valve suitable for filling gas supply system field. Background technique [0002] In the ground gas supply system and cryogenic refueling system of the current carrier type, the working performance index of the solenoid valve, the quickness and reliability of the two-way switching response have a key impact on the overall performance and mission reliability of the system. When the existing solenoid valve is used, there are problems of poor flexibility and reliability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-pressure two-way switching electric cut-off valve, which is applied to the ground air supply system and low-temperature filling system of the vehicle type, and its function is to control the connector and the filling valve to realize the two-way gas path The purpose of switching, and has high flexibili...
