Description
Technical field
The utility model relates to a kind of sentinel valve field, especially a kind of coating type electromagnetic impulse valve.
Background technique
Along with country is to the input of environmental protection industry, environmental protection industry (epi) has welcome the another of development and has taken turns peak, sentinel valve is as the key fitment of deduster, its performance directly has influence on the working life of deduster, but existing sentinel valve complex structure, its little vent hole is arranged on bonnet usually, once there is the situation of vent hole damage, is often difficult to change accessory and maintenance.In addition, the surface of sentinel valve is not through process, and after long-time use, be easily corroded, therefore its anti-corrosion capacity is poor, is easily stained with ash, affects working life.
In view of this, the utility model proposes a kind of electromagnetic impulse valve of designs simplification, adopt the pilot head component little air vent and pilot head being integrated in one, add the compatibility of electromagnetic impulse valve part, simplified structure, saves material, can when little air vent is damaged, directly completing reparation by changing pilot head component, making maintenance process more convenient.In addition, the electromagnetic impulse valve that the utility model proposes also is coated with polytetrafluorethylecoatings coatings, when working under the rugged environment such as make it out of doors, can prevent corrosion, not easily covered with dust.Electromagnetic impulse valve of the present utility model can be widely used in environmental protection industry, especially has a wide range of applications in bag-type dust industry.
Model utility content
Coating type electromagnetic impulse valve provided by the utility model, comprise pilot head component, be provided with the bonnet of little damping hole, be provided with the valve gap in final reliel hole, be provided with the valve body of output terminal and large damping hole, wherein, described pilot head component is arranged on bonnet, bonnet is arranged on valve gap, and the air cavity that described bonnet and valve gap are formed is divided into two air chambers by Small diaphragm-piece assembly; The air cavity that described valve body and valve gap are formed is divided into rear gas chamber and front air chamber by large diaphragm unit, and described pilot head component is provided with little vent hole, and described pilot head component adopts with bonnet and is threaded, and the surface of described electromagnetic impulse valve is coated with corrosion-inhibiting coating.
Described corrosion-inhibiting coating adopts polytetrafluorethylecoatings coatings.
The coating type electromagnetic impulse valve that the utility model provides, by adopting pilot head component, adds the compatibility of electromagnetic impulse valve part, simplifies the structure, saved cost of material, be convenient to part maintain and replace.In addition, electromagnetic impulse valve of the present utility model also by coating polytetrafluorethylecoatings coatings, improves its corrosion resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the coating type electromagnetic impulse valve that the utility model one embodiment provides.
Embodiment
Understand for the ease of those of ordinary skill in the art and implement the utility model, below in conjunction with the drawings and the specific embodiments, the utility model being described in further detail.
As shown in Figure 1, the coating type electromagnetic impulse valve that the present embodiment provides, comprise pilot head component 3, be provided with the bonnet 5 of little damping hole 8, be provided with the valve gap 10 in final reliel hole 9, be provided with the valve body 13 of output terminal and large damping hole 14, wherein, described pilot head component 3 is arranged on bonnet 5, bonnet 5 is arranged on valve gap 10, and the air cavity that described bonnet 5 and valve gap 10 are formed is divided into two air chambers by Small diaphragm-piece assembly 7; The air cavity that described valve body 13 and valve gap 10 are formed is divided into rear gas chamber 11 and front air chamber 15 by large diaphragm unit 12, described pilot head component 3 is provided with little vent hole 2, described pilot head component 3 adopts with bonnet 5 and is threaded, and the surface of described electromagnetic impulse valve is coated with corrosion-inhibiting coating.Described corrosion-inhibiting coating adopts polytetrafluorethylecoatings coatings.Electromagnetic coil 4 is fixed in described pilot head component 3 by coil housing pin 1.Small diaphragm-piece assembly 7 is connected with described bonnet 5 by little spring 6; Large diaphragm unit 12 is connected with described valve gap 10 by big spring 16.
The air cavity of electromagnetic impulse valve of the present utility model is divided into former and later two air chambers by large diaphragm unit, and the direction of arrow in Fig. 1 represents that air-flow moves towards.When gas bag is filled with pressurized air body in sentinel valve, pressurized air enters rear gas chamber through large damping hole, and the pressure of rear gas chamber makes the output port on the diaphragm shutoff valve body in large diaphragm unit, and electromagnetic impulse valve is closed.
When electromagnetic impulse valve works, the electrical signal of pulsation blowing control instrument drives the dynamic iron core in electromagnetic pilot head to move, open little vent hole, air chamber pressure above Small diaphragm-piece assembly reduces, on Small diaphragm-piece assembly, lower chamber produces pressure difference, Small diaphragm-piece is moved backward, thus open the final reliel hole of rear gas chamber, the pressure of rear gas chamber is reduced rapidly, poor with front air chamber mineralization pressure, large diaphragm unit moves backward, opens the output port on valve body, thus the pressurized air in gas bag is sprayed by the output terminal on valve body, electromagnetic impulse valve is opened.
When pulsation blowing control instrument electrical signal stops, the dynamic iron core of electromagnetic pilot head returns, the little vent hole of shutoff, at this moment pressurized gas enters air chamber above Small diaphragm-piece assembly from little damping hole, produce pressure difference, Small diaphragm-piece assembly moves forward, shutoff final reliel hole, at this moment rear gas chamber is in closed state, and pressurized air enters rear gas chamber by large damping hole, and rear gas chamber's pressure gos up fast, produce pressure difference, the diaphragm of large diaphragm unit is moved forward, and the output terminal again on shutoff valve body, makes electromagnetic impulse valve close.
The embodiment of the above is better embodiment of the present utility model; not limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence change that all shapes according to the utility model, structure are done all comprises in protection domain of the present utility model.
