Technical Field

The invention relates to the technical field of suspension blowers, in particular to an electromagnetic pneumatic emptying valve.

Background

The suspension blower (compressor) has been widely used in various production fields in society, and stable operation is a basic requirement of the suspension blower (compressor). When the suspension air blower (compressor) is used, no-load starting needs to be guaranteed, if a surge condition occurs, timely response needs to be carried out, damage to a machine is avoided, and when the suspension air blower (compressor) is stopped, emptying is carried out. The problems need to be solved by installing a vent valve, the vent valve used in most of existing suspension blowers (compressors) is an electric valve, and the electric valve is characterized by slow response, long time is needed for opening the valve clack, and the emergency can not be effectively treated, so that the fault rate of the machine is increased. The electric valve has larger volume and large mass, is inconvenient to install and use and causes great inconvenience for users. Therefore, a need exists for a quick response blow-down valve.

Disclosure of Invention

The invention aims to solve the technical problems in the prior art and provide an electromagnetic pneumatic emptying valve which is quick in response and convenient to install.

In order to achieve the aim, the electromagnetic pneumatic air release valve is characterized by comprising a piston, a connecting rod, an air bag and an air pipe,

the piston, the connecting rod and the air bag are connected into a whole through bolts in sequence and are installed in the shell, the piston can move along the central axis of the front port of the shell, and two ends of the air pipe are connected to the air bag and the electromagnetic valve respectively.

Preferably, the electromagnetic pneumatic emptying valve further comprises a flange blind plate and an emptying port, the emptying port is arranged at the rear end of the shell, one end of the flange blind plate is connected with the threaded hole of the shell through a bolt, and the other end of the flange blind plate is connected with the emptying port through a reinforcing rib.

Preferably, the rear end of the air bag is fixed on the flange blind plate.

Preferably, the air pipe passes through an air pipe interface of the flange blind plate.

Preferably, the electromagnetic valve is arranged on an air outlet of the suspension blower.

Preferably, the front port of the housing is connected to the air outlet of the levitation blower by a clip.

Preferably, the evacuation port is connected with the protrusion on the inner wall of the housing in a matched manner through the groove of the evacuation port.

Preferably, the vent is divided into four flow channels by the reinforcing ribs.

Compared with the prior art, the invention has the advantages that:

1. the piston can move along the central axis of the front port of the shell and can rapidly discharge compressed air flow by matching with four flow channels of the emptying port;

2. the front port of the shell is connected with the air outlet of the suspension blower through the clamp, so that the shell is convenient to disassemble and assemble.
