Problems solved by technology

[0003] In the past, the poppet valve used rubber or rubber sealing ring for surface contact sealing, which could not adapt to high temperature flue gas, and was easy to drop and age, and the sealing effect was not very good. It was sealed with a steel plate, citing the deformation of the steel plate, and the deformation of the steel plate Finally, there is a gap in the sealing contact surface, which directly leads to a decrease in the sealing effect

Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0010] As shown in the figure: the air inlet valve seat 7 is set on the box body 1, and the air outlet port is opened on the box body 1, and a port with a size larger than the air inlet valve seat 7 is provided above the air inlet valve seat 7 in the box body 1. The rigid valve plate 6, the valve plate 6 is set on the reinforcement plate 5, the air inlet valve seat 7 is tubular and protrudes into the box body 1, so that the outlet end of the air inlet valve seat 7 is in contact with the valve plate 6 is in line contact, and the reinforcing plate 5 is connected with the lifting device.

[0011] A support 2 is provided on the outer wall of the box 1, and the lifting device includes a cylinder 3 arranged on the support 2. The piston rod 4 of the cylinder 3 extends into the box 1, and the end of the piston rod 4 is connected by a locking device 8. There are reinfo...

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 [0001] The invention relates to a lift valve, in particular to a steel lift valve for a bag-type pulse dust collector. Background technique [0002] The fully open airtight valve, also known as the poppet valve, is generally used for the dust removal valve of the high-temperature purification air duct. In the dust removal and dust collector with separate chambers and reverse blowing, the valve is an important part of the dust removal equipment. It is closed when cleaning the dust. Open it when vacuuming, and its working condition directly affects the dust removal effect, dust removal efficiency and life of the dust collector. [0003] In the past, the poppet valve used rubber or rubber sealing ring for surface contact sealing, which could not adapt to high temperature flue gas, and was easy to drop and age, and the sealing effect was not very good. It was sealed with a steel plate, citing the deformation of the steel plate, and the deformation of the steel pl...
