Piston Pulse Valve

Qingdao Star Machine provides V1614718 Piston Pulse Valve, it is based on diaphragm electromagnetic pulse valve and piston mechanism design, adopting embedded structure, with stronger blowing performance and longer service life. Its core features are:

Structural features

Composed of electromagnetic pilot head, piston and valve body, the area of piston rear chamber is larger than the front chamber, and the pneumatic force ensures sensitive closing state.

Cancellation of rubber diaphragm and pressure spring, the use of high-strength piston structure, significantly improve the durability.

The working principle of Piston Pulse Valve is divided into two stages:

Blowing state: After the signal is inputted by the electric controller, the electromagnetic pilot head opens the unloading hole, and the pressure gas in the front chamber of the piston lifts up the piston and opens the blowing channel.

Closed state: after the signal disappears, the unloading hole is closed, the gas pressure in the back chamber of the piston pushes the piston to reset, and the channel is closed.

Technical Standard

Working pressure: 0.2~0.6MPa

Voltage specification: DC24V or AC220V/50Hz

Protection grade: IP65

Working medium: clean air

Applicable temperature: room temperature type -25~85℃, high temperature type -25~230℃.

Life span: 1 million times

Installation specification of Piston Pulse Valve

Sealing Requirements: The threaded connection should be filled with PTFE raw material tape or thread sealant, and the combined surface of the air distribution box should be smooth and clean.

Air source processing: the air inlet pipe of the air distribution box should be installed with a filter and regulator, and the bottom is equipped with a drain valve to ensure that the compressed air is dry and free of impurities.

Processing accuracy: the air package installation end face according to Figure 2 processing, to ensure that the size tolerance and surface roughness.

Cleaning Requirements: The air bag and blowpipe should be thoroughly cleaned before installation to avoid residual debris.

Connection

When installing with the round manifold, the dimensions should be according to Fig. 3 to ensure the matching of the connection (e.g. Φ150/Φ120 aperture).

The machining diagram of the manifold connection (Fig. 2) specifies the key dimensions: 180 mm total width, 15° chamfer, δ = 4.5 mm wall thickness.

External dimensions

The external dimensions of the 3-inch Piston Pulse Valve are shown in Figure 3, with key parameters such as total length of 134mm and mounting holes of Φ151mm marked.

With compact design and flexible blowpipe arrangement, the valve is suitable for the demand of high efficiency ash cleaning in industrial dust removal system. By optimising the piston structure and electromagnetic control, it achieves fast response and stable operation, and meets the stringent requirements of reliability and precision for export products.
