A gas-liquid dual-purpose solenoid valve

Abstract

The invention discloses a gas-liquid dualpurpose electromagnetic valve. The gas-liquid dualpurpose electromagnetic valve comprises control rods, filters, a speed adjuster, a display, a power supply interface, liquid discharge pipes, a gas inlet pipe, a shell, exhaust pipes, a liquid inlet pipe, electromagnets, a valve body, a movable rod and a sealing ring. The gas-liquid dualpurpose electromagnetic valve has the following beneficial effects: a traditional gas electromagnetic valve and a traditional liquid electromagnetic valve are combined as a whole, and the speed adjuster is mounted to synchronously satisfy adjustment of directions, flows, speeds and other parameters of gas and liquid mediums; for some machinery, some components are used for hydraulic pressure, and some components are suitable for gas pressure; and the gas-liquid dualpurpose electromagnetic valve can synchronously consider transmission of gas and liquid, prevents synchronous installation of gas and liquid electromagnetic valves, has no need to add a speed adjusting valve, saves the cost, controls the gas and liquid mediums in a concentrated manner, simplifies the operation flow, provides convenience for operators, is provided with the display for instantly displaying the flowing speed, the pressure and the like of the gas and liquid mediums, and is safer and more reliable.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a gas-liquid dual-purpose solenoid valve, which belongs to the technical field of fluid control. Background technique [0002] Solenoid valve is an industrial equipment controlled by electromagnetic. In the industrial control system, it plays an important role in adjusting the direction, flow, speed and other parameters of the medium. At the same time, the solenoid valve can cooperate with different circuits to achieve the expected control. The controlled Accuracy and flexibility can be guaranteed, but the traditional solenoid valve simply controls the transmission of a certain gas or liquid medium, and many solenoid valves need to be installed on many machines, and a speed control valve must also be installed, resulting in an increase in the installation process , it is impossible to realize a solenoid valve to control the transmission of gas-liquid medium at the same time, and each solenoid ...

[0002] Solenoid valve is an industrial equipment controlled by electromagnetic. In the industrial control system, it plays an important role in adjusting the direction, flow, speed and other parameters of the medium. At the same time, the solenoid valve can cooperate with different circuits to achieve the expected control. The controlled Accuracy and flexibility can be guaranteed, but the traditional solenoid valve simply controls the transmission of a certain gas or liquid medium, and many solenoid valves need to be installed on many machines, and a speed control valve must also be installed, resulting in an increase in the installation process , it is impossible to realize a solenoid valve to control the transmission of gas-liquid medium at the same time, and each solenoid valve needs to be controlled separately, which is not convenient for the operator to control. The traditional solenoid valve only installs a filter on the inlet pipe. If the solenoid valve is impurity, it is easy to block the medium export, therefore, a gas-liquid dual-purpose electromagnetic valve is proposed for the above problems
