Description
Technical field
The utility model relates to air cleaning facility field, refers to a kind of poppet valve especially, and the utility model also relates to a kind of three way poppet valve comprising described poppet valve.
Background technique
In existing operation garbage incinerator tail gas treatment process, most of project adopts semidry method rotating spraying extracting tower process+dry powder to spray protection+active carbon injection+sack cleaner treatment process.In the process, in order to ensure that the safe handling of sack cleaner makes the direct by-passing of flue gas in an emergency situation, three way poppet valve is set at sack cleaner entrance.By lifting or the landing of three way poppet valve, flue gas is made to select by-passing or walk main road.Whether up to standard most important to dust emission index in flue gas of the sealability of three way poppet valve.Tradition three way poppet valve shortcoming: adopt individual layer valve plate, valve flange is that thick steel sheet adds stiffening rib, and adopt rigid contact between valve and valve seat, elevated-temperature seal bar is established in centre.This design is very high to the field erected requirement of poppet valve, and due to in-site installation condition, be difficult to ensure to install valve plate and the perpendicularity of lifting arm and the level of valve seat, when this valve plate contacts with valve seat, very difficult guarantee seals completely.Cause gap to increase after the of long duration aging compression of elevated-temperature seal adhesive tape in addition, ash-laden gas can leak to bypass flue by valve plate and valve base chamber space thus, and causes exhaust gas dust exhaust index to exceed standard.
Model utility content
The utility model proposes a kind of poppet valve, solve the problem that sealability in prior art is bad.
The utility model also proposed a kind of three way poppet valve, has good seal performance, the feature of long service life.
The technical solution of the utility model is achieved in that a kind of poppet valve, comprise: lifting arm, lifting valve base and lifting cylinder, described lifting valve base is used for fixed position, described lifting cylinder to be positioned at above described lifting valve base and to be connected with described lifting arm, described lifting arm upper end is inserted in described lifting valve base, described lifting arm bottom connected double-layer valve plate and valve seat, by double-deck valve plate and valve seat, can effectively lift-off seal performance.
Further, described lifting arm lower end is connected with the first valve plate, the first valve seat, the second valve plate and the second valve seat from top to bottom in turn, also be provided with elevated-temperature seal adhesive tape in described first valve seat, the valve plate link by column between described first valve plate and described second valve plate is connected and fixed.
Further, described valve plate link is that elongated hole connects, thus possesses certain adjustment space.
Further, between described first valve plate and described second valve plate, be also provided with spring, increase described elevated-temperature seal adhesive tape aging after contact sealing.
Further, heated sealant wind system is also provided with between described first valve plate and described second valve plate, described heated sealant wind system comprise be tightly connected described first valve plate and described second valve plate thin-wall stainless steel plate and can switching air inlet, described thin-wall stainless steel plate is attached to described first valve plate and described second valve plate edge, form a seal space, because described thin-wall stainless steel plate has certain elasticity, specific rigidity plate better can seal with valve base chamber and contact, after the air after blast heating between described first valve plate and described second valve plate, make to keep micro positive pressure between two-layer valve plate, ensure that dust-containing airflow can not from valve plate gap leakage.
A kind of three way poppet valve, comprises described poppet valve.
Further, described three way poppet valve, comprise valve body, be positioned at the suction port at described valve body rear, be positioned at the main road air outlet in described valve body front, and the bypass air outlet above described main road air outlet, described lifting valve base is fixed on above described valve body, described lifting arm, described first valve plate and described second valve plate are all positioned at described valve inner, and connect with described valve interior wall.
The beneficial effects of the utility model are: by double-deck valve plate and valve seat, can effectively lift-off seal performance.
Accompanying drawing explanation
