A poppet valve used in a dust collector

Release time:2022-08-24  Click:420

In the production of iron and steel, non-ferrous metallurgy, building materials, and chemical industries, a large amount of harmful gases containing dust particles will be produced. If it is directly discharged, it will pollute the air and seriously affect the health of residents. With the strengthening of the state's supervision of environmental protection, various enterprises have put forward high requirements for the treatment of dusty gases. At present, the bag filter is widely used to purify the dusty flue gas, and the bag filter has a wide range of applications. The air pipeline of the bag filter often needs to open and close the air. Generally, a poppet valve is used to realize this operation function. The poppet valve is mainly composed of a driving cylinder, a connecting rod, a valve plate, a solenoid valve, etc. The cylinder, connecting rod, etc. The valve plate and the valve plate are connected by threaded hard connection, and the valve plate and the sealing surface are in hard contact after the poppet valve is closed, and the valve plate is prone to unstable phenomena such as shaking and tilting during the lifting and closing process, resulting in the valve plate and the sealing surface not being very good. The sealing performance is poor, and the vibration and impact brought by the lifting can easily damage the cylinder and cannot be used normally.

In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a poppet valve with good sealing performance and stable operation.  

This utility model will apply for a patent on November 2, 2021, and the patentee is Ningbo Changqing Environmental Protection Technology Co., Ltd. The product is realized by the following technical measures: a poppet valve used in a dust collector, including a cylinder used to provide power for lifting, a flower plate is arranged directly below the cylinder, wherein the cylinder is fixed by a reinforcing plate On the top cover, a floating joint is installed on the head of the cylinder, and an upper sealing valve cover is installed at the other end of the floating joint, and the upper sealing valve cover is composed of a steel plate and a sealing gasket; a lower sealing seat ring, the lower sealing seat ring is provided with a layer of sealing gasket, and the distance between the lower sealing seat ring and the upper sealing valve cover is smaller than the stroke of the cylinder; The guide structure for the up and down movement of the upper sealing valve cover.

Compared with the prior art, the advantages of the present utility model are: by adding a floating joint, since the floating joint can rotate freely, the rigid stress during the movement of the cylinder can be eliminated, and the service life of the poppet valve can be increased; The reinforcement plate increases the force-bearing area of ​​the top cover, so that the top cover will not be deformed, and the stability of the poppet valve is increased; the sealing gasket is fixed on the steel plate that seals the valve cover, which enhances the sealing performance. Thus, the technical problems of poor sealing performance and unstable and reliable operation in the prior art are solved.
