Abstract
The utility model discloses a kind of poppet valve for dedust air duct, it comprises valve body, bearing, cylinder and coupling shaft, described cylinder is fixedly installed on bearing, bearing is arranged on valve body, valve body has intake grill and exhaust outlet, and described valve body comprises valve plate, and described cylinder piston rod and coupling shaft one end are threaded connection, the coupling shaft the other end and valve plate are threaded connection, and described valve plate is arranged at intake grill place, valve plate can cover intake grill.A kind of poppet valve for dedust air duct that the utility model proposes, replaces existing butterfly valve, has met the needs that in dust pelletizing system, dust sucting point is controlled, the air quantity that ensures dust pelletizing system air quantity and design matches, improved dust pelletizing system working efficiency, Simultaneous Stabilization is reliable, not fragile.
Description
Technical field
The utility model relates to the dusting apparatus of industrial field dust-containing airflow (flue gas), and concrete is a kind of poppet valve for dedust air duct.
Background technique
Dust pelletizing system is mainly comprised of gas collection dust shield, valve, admission line, deduster, ash-transmission system, fan motor, silencing apparatus, exhaust chimney etc.In dust pelletizing system, for the multiplex butterfly valve of switching of each dust sucting point, control at present, when dust sucting point is worked, butterfly valve is opened, otherwise butterfly valve cuts out.Along with the frequent open and close of butterfly valve, disc-type spool and valve body contact wear, butterfly valve is easily malfunctioning and cause dust sucting point air quantity not or cut out.In order to address this problem, many built dust pelletizing systems for a long time in opening state, cause systematic air flow not mate with design air flow butterfly valve, on-the-spot post dust exceeding.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of poppet valve for dedust air duct, replace existing butterfly valve, meet the needs that in dust pelletizing system, dust sucting point is controlled, the air quantity that ensures dust pelletizing system air quantity and design matches, improve dust pelletizing system working efficiency, this poppet valve is reliable and stable, not fragile simultaneously.
For realizing above-mentioned technique effect, the utility model provides a kind of poppet valve for dedust air duct, it comprises valve body, bearing, cylinder and coupling shaft, described cylinder is fixedly installed on bearing, and bearing is arranged on valve body, and valve body has intake grill and exhaust outlet, described valve body comprises valve plate, described cylinder piston rod and coupling shaft one end are threaded connection, and the coupling shaft the other end and valve plate are threaded connection, and described valve plate is arranged at intake grill place, valve plate can cover intake grill; During dust sucting point work, signal is given to cylinder, and cylinder piston drives valve plate to move upward, and now intake grill is opened; When dust sucting point quits work, signal is given to cylinder, and cylinder presses down and drives valve plate to move downward to make valve plate sealing intake grill.
For preventing that dust from wearing and tearing to valve plate, on described valve plate, be also provided with wear-resistant material layer.
A kind of poppet valve for dedust air duct that the utility model proposes, replaces existing butterfly valve, has met the needs that in dust pelletizing system, dust sucting point is controlled, the air quantity that ensures dust pelletizing system air quantity and design matches, improved dust pelletizing system working efficiency, Simultaneous Stabilization is reliable, not fragile.
Accompanying drawing explanation
Fig. 1 is a kind of poppet valve arrangements schematic diagram for dedust air duct;
Fig. 2 is the plan view of Fig. 1.
Embodiment
Referring to accompanying drawing, a kind of poppet valve for dedust air duct, it comprises valve body 3, bearing 2, cylinder 1 and coupling shaft 8, described cylinder is fixedly installed on bearing, and bearing is arranged on valve body, and valve body has intake grill 7 and exhaust outlet 6, described valve body comprises valve plate 4, described cylinder piston rod and coupling shaft one end are threaded connection, and the coupling shaft the other end and valve plate are threaded connection, and described valve plate is arranged at intake grill place, valve plate can cover intake grill; During dust sucting point work, signal is given to cylinder, and cylinder piston drives valve plate to move upward, and now intake grill is opened; When dust sucting point quits work, signal is given to cylinder, and cylinder presses down and drives valve plate to move downward to make valve plate sealing intake grill.
For preventing that dust from wearing and tearing to valve plate, on described valve plate, be also provided with wear-resistant material layer 5.
A kind of poppet valve for dedust air duct that the utility model proposes, replaces existing butterfly valve, has met the needs that in dust pelletizing system, dust sucting point is controlled, the air quantity that ensures dust pelletizing system air quantity and design matches, improved dust pelletizing system working efficiency, Simultaneous Stabilization is reliable, not fragile.
