Description

TECHNICAL FIELD

[0001] The utility model relates to valve equipment technical field, especially a new pneumatic diaphragm valve. BACKGROUND

[0002] Pneumatic diaphragm valve is a common industrial control valve, the movement of the diaphragm in the valve is controlled by the air pressure signal, and the fluid is regulated. The main structure of the pneumatic diaphragm valve includes a valve seat, a valve core, and a pneumatic device. The valve core is vertically located in the valve seat. The pneumatic device includes a connecting shaft, a diaphragm, and a housing. The diaphragm is sealed in the middle of the housing. The upper end of the connecting shaft and the lower middle part of the diaphragm are installed together. The upper end of the housing has an air inlet pipe on the side. In the specific working process, the pressure of the compressed air entering the housing is adjusted to control the flow of the medium output by the valve seat. When the diaphragm is driven by the compressed air through the connecting shaft to drive the valve core to move downward with a relatively large interval, the flow passage in the valve seat is relatively small, and the flow of the liquid medium flowing from one end of the valve seat to the other end is relatively small. When the diaphragm is driven by the compressed air through the connecting shaft to drive the valve core to move downward with a relatively small interval (the springs on both sides of the housing make the diaphragm move upward), the flow passage in the valve seat is relatively large, and the flow of the liquid medium flowing from one end of the valve seat to the other end is relatively large.

[0003] Although the existing pneumatic diaphragm valve meets the flow control needs of the fluid to some extent, it also has some disadvantages due to the structure. Specifically, the staff needs to adjust the gas pressure entering the housing on site, and then achieve the purpose of adjusting the medium flow in the valve seat. This method will more or less bring inconvenience to the staff, and when the pneumatic diaphragm valve is located at a high place or a production-related position that is not convenient to operate, the disadvantage is more obvious. Therefore, it is particularly necessary to provide a pneumatic diaphragm valve that can be conveniently operated by non-contact mode for the staff. UTILITY MODEL CONTENTS

The solenoid valve DC1 is powered on and the valve core is opened (the solenoid valve DC2 is powered off and the valve core is closed), and the compressed air output by the air compressor enters the shell 101, so that the valve core of the pneumatic diaphragm valve body 1 drops, and the liquid flow output by the pneumatic diaphragm valve body 1 becomes relatively small.
