It is easy to fall off.The opening and closure of seal isolation lid are finally realized using cylinder.
Wherein, immersion oil packing applies heat-resisting lubricating oil and the asbestos yarn braiding of graphite is formed, it is adaptable to gyroaxis, toward resurrection
Make encapsulant on plug or valve lever.Medium is steam, air, water for industrial use, heavy crude product.
Preferably, the slideway side is communicated with a topping-up passage, entrance of the topping-up passage on slideway is located at
The outside of sealing ring isolating valve gate seat inner chamber.
Type sealing ring and cylinder power transmission shaft are lubricated by topping-up passage, cylinder-driven axle will not it is stuck, fracture, carry
High service life.
Preferably, the port of export of second port and third connectivity mouth is connected to a loose flange.
Loose flange bottom mounting surfaces are sealed using immersion oil packing or O-ring or asbestos twisted rope, than the paper of conventional air valve
Pad sealing, easy accessibility, good sealing effect.The flange of two mounting surfaces can be with 360 ° of rotations, without the need for specially going to consider and its phase
The bolt hole position on Pipe installing flange for connecing, it is easy for installation.Loose flange is in pipe using flange, steel loop etc. flange sleeve
On end, flange can the activity on pipe end.Steel loop or flange are exactly sealing surface, and the effect of flange is then that they are compressed.
Preferably, being connected with a bellows between second port and the loose flange that connects thereon.
Combustion air valve bottom adopts bellows, the axiality of bottom connecting line, the depth of parallelism of contact surface, installation
Can freely be corrected by bellows when highly, having deviation, installation, convenient disassembly.
Beneficial effect：The inlet end of the utility model combustion air valve and outlet side do not have a directionality, and traditional air
Valve can only one-way ventilating, by seal isolation lid, immersion oil asbestos packing and packing mounting ring composition mechanism air is carried out it is close
Envelope, sealing structure is simple, sealing effectiveness is good, be unlikely to deform at sealing.And immersion oil asbestos packing is arranged on packing mounting ring
