Abstract
The utility model discloses a novel exhaust solenoid valve, including valve body and valve rod, the valve body both ends are provided with air inlet and gas outlet respectively, install the valve rod on the valve body, the case is installed to the valve rod bottom, the inner groovy has been seted up to the case bottom. The utility model increases the positive pressure space of air exhaust by arranging the inner groove at the bottom end of the valve core, so that the electromagnetic valve can work normally when positive pressure air exhaust or vacuum air suction (air exhaust); and a protective layer is arranged between the valve core and the valve rod, so that the service life of the device can be prolonged.
Description
Technical Field
The utility model relates to an exhaust solenoid valve technical field specifically is a novel exhaust solenoid valve.
Background
The electromagnetic valve is an industrial device controlled by electromagnetism, is an automatic basic element for controlling fluid, belongs to an actuator, is not limited to hydraulic pressure and pneumatic pressure, is used for adjusting the direction, flow, speed and other parameters of a medium in an industrial control system, can be matched with different circuits to realize expected control, and can ensure the precision and flexibility of the control. There are many types of solenoid valves, with different solenoid valves functioning at different locations in the control system, the most common being one-way valves, safety valves, directional control valves, speed control valves, etc.
An exhaust electromagnetic valve is a device which can be used under both positive pressure and negative pressure (vacuum), and the existing electromagnetic valve is shown in figure 2, and after the exhaust electromagnetic valve is used for about three months, the work is abnormal, the exhaust speed is low, and the work efficiency is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel exhaust solenoid valve to solve the problem among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme: a novel exhaust electromagnetic valve comprises a valve body and a valve rod, wherein an air inlet and an air outlet are respectively formed in two ends of the valve body, the valve rod is installed on the valve body, a valve core is installed at the bottom end of the valve rod, and an inner groove is formed in the bottom end of the valve core; and a protective layer is arranged between the valve core and the valve rod.
Preferably, the protective layer is a modified nylon layer.
Preferably, the valve further comprises a communication hole, and the inner groove of the valve core corresponds to the communication hole of the valve body.
Preferably, the valve element has an outer diameter larger than that of the communication hole.
Compared with the prior art, the beneficial effects of the utility model are that: the inner groove is formed at the bottom end of the valve core, so that an exhaust positive pressure space is increased, and the electromagnetic valve can normally work when positive pressure exhaust or vacuum suction (exhaust) is performed; and a protective layer is arranged between the valve core and the valve rod, so that the service life of the device can be prolonged.
