Abstract
The invention relates to a lift valve, in particular to a steel lift valve used for a bag-typed pulse dust collector. According to the technical proposal provided by the invention, an intake valve base is arranged on a box body, an outlet is arranged on the box body, the inside of the box body over the intake valve base is provided with a steel valve plate the size of which is larger than that of the port of the intake valve base, the valve plate is arranged on a reinforcing plate, and the intake valve base takes a shape of a tube and bulges to the inside of the box body, thus leading the output port of the intake valve base to contact lineally with the valve plate; the strengthen plate is connected with a lift device. The invention changes the surface contact sealing into the line contact sealing, and leads the seal effect to be improved, the outlet air stream to be stable, and the strength of valve plate and the durability to be improved.
Description
Technical field
The present invention relates to a kind of lift valve, especially a kind of pocket type pulsed dust collector with rigid lifting valve.
Background technology
The full-open type airtight valve, claim lift valve again, the deashing valve that generally is used for the high temperature purification air channel, in the ash cleaning and dust removing device of chamber-dividing counter-blowing, valve is the important component part of cleaner, it is closed when deashing, opens during dust suction, and the quality of its working condition directly influences ash-removal effect and the efficiency of dust collection and the life-span of deduster.
Lift valve in the past all adopts rubber or rubber seal to carry out face contact sealing, can not adapt to high-temperature flue gas, drop reaches aging easily again, and sealing effectiveness is not fine, adopt the sealing of rigidity steel plate, the distortion of quoting steel plate is behind the steel plate deformed, make sealing contact surface have the slit, directly cause sealing effectiveness to descend.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of face contact sealing change line contact sealing, good sealing effect into, the steady air current of giving vent to anger, the intensity of valve plate and the pocket type pulsed dust collector with rigid lifting valve that all improves service life.
According to technical scheme provided by the invention, the air inlet valve seat is set on casing, offer the gas outlet on the casing, in casing, be provided with the rigidity valve plate of size above the air inlet valve seat greater than air inlet valve seat port, described valve plate is arranged on the stiffener, the air inlet valve seat is thing and to the casing internal projection in a tubular form, makes the port of export of air inlet valve seat be line with valve plate and contact that described stiffener links to each other with lowering or hoisting gear.
Be provided with bearing at cabinet exterior, described lowering or hoisting gear is included in the cylinder that is provided with on the bearing, and the piston rod of cylinder stretches in the casing, and the piston rod end is connected with stiffener by locking device.
The present invention changes face contact sealing into line contact sealing, makes sealing effectiveness improve, the steady air current of giving vent to anger, and the intensity and the service life of valve plate all improve.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: air inlet valve seat 7 is set on casing 1, offer the gas outlet on the casing 1, in casing 1, be provided with the rigidity valve plate 6 of size above the air inlet valve seat 7 greater than air inlet valve seat 7 ports, described valve plate 6 is arranged on the stiffener 5, air inlet valve seat 7 is thing and to casing 1 internal projection in a tubular form, make the port of export of air inlet valve seat 7 be line and contact that described stiffener 5 links to each other with lowering or hoisting gear with valve plate 6.
Be provided with bearing 2 at casing 1 outer wall, described lowering or hoisting gear is included in the cylinder 3 that is provided with on the bearing 2, and the piston rod 4 of cylinder 3 stretches in the casing 1, and piston rod 4 ends are connected with stiffener 5 by locking device 8.
During installation, cylinder 3 is above cylinder saddle 2, and cylinder saddle 2 is connected with casing 1, cylinder 3 and valve stiffener 5 and valve plate 6 vertical installations, and the piston rod 4 that moves on cylinder 3 axis is connected with the valve center, and its connected mode adopts locking device 8 to connect.Cylinder 3 and valve plate 6 vertical installations, piston rod 4 is connected with stiffener 5 and valve plate central vertical.
The present invention compares with butterfly valve or flap valve that the industrial dedusting device generally uses, has more superiority.Because, butterfly valve or flap valve since during standard-sized sheet valve plate horizontal drag losses is bigger at the valve body center, back suction dirt effect reduces, and increases the blower fan resistance, has promptly increased power of fan, and has caused the air inlet air turbulence in the air channel.
During the deduster operate as normal, lift valve is opened, and cylinder 3 is in closes (rising) state, and lift valve cuts out during deashing, cylinder 3 is in pressed status, owing to adopt the sealing of rigidity valve plate, good airproof performance, ash-removal effect is good, is not subjected to the air-flow Temperature Influence, and the scope of application is wide.During operate as normal, valve plate 6 rises to the valve body upper end, purifies flue gas and enters air channel dust suction work by air inlet valve seat 7, can not cause disorder to the air inlet air-flow in the air channel.
The present invention is zero at the out-of-date resistance of air communication, purifies air channel air-flow advection during dust suction, and is simple in structure, dependable performance, adjustability is good, adapt to especially rubber packing can not heatproof the high temperature purification flue gas, seal does not have aging phenomenon, long service life, good airproof performance.
