Abstract
The utility model relates to a lining type butterfly valve which comprises a lining, a valve body, a butterfly plate and an axis. The rubber lining 1 is arranged on the valve body 2 in order to make the inner bore of the valve body be a flexible bore, the bore wall is respectively provided with two O-shaped sealing rings 3, when the butterfly plate is closing, the inner bore rubber can be compressed in order to reach the sealing effect. The upper end of the rod is respectively provided with two O-shaped sealing rings in order to get an excellent sealing function, all the sealing rings are arranged in one lining, the two sides of the lining are provided with tooth-shaped sealing grooves 4, and the rubber lining can complete the sealing of the axis and the bore simultaneously.
Description
Technical field
The utility model relates to butterfly valve.
Background technique
Existing reed valve, because having, it opens plurality of advantages such as convenient, be widely adopted vacuum industry especially, transformer industry and other industries, with regard to its seal form, can be divided into two classes at present, 1, rigid seal: because of its in foozle, assembly error and cumulative error, do not reach sealing effect fully, now withdraw from the market just gradually.2, soft sealing: the soft seal butterfly valve of domestic production at present belongs to the axial seal form.Promptly open a groove on the butterfly sheet, load onto " 0 " RunddichtringO hole wall and seal, because the existence of foozle and " 0 " type circle are blocked, squeeze phenomenon, sometimes even be cut off, and it makes precision prescribed height, complex structure, cost costliness.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of, and the thought that breaks traditions pattern adopts rubber bushing, realizes the sealing of valve body with the soft seal form.
The utility model working principle is as follows: be made up of lining 1, valve body 2, butterfly sheet and axle, rubber bushing 1 is contained on the valve body 2, makes valve body inner bore become a soft hole, hole wall respectively has 2 roads " 0 " type sealing 3, when the butterfly sheet is closed, with the compression of endoporus rubber, thereby reach sealing effect, and the bar upper end respectively there is 2 roads " 0 " type sealing, play the excellent sealing function, all on a lining, the lining both sides are provided with profile of tooth seal groove 4 in all sealings, and it can finish the sealing in axle and hole simultaneously rubber bushing.
The utlity model has following advantage:
1, structure is the simplest, and accuracy of manufacturing is relatively low, greatly reduces cost.
2, sealing is reliable, can be widely used in water, and oil, the sealing of gas uses future extensive
3, stable performance, can be under-30 ℃ of-170 ℃ of temperature proper functioning.
4, novel structure, both ends of the surface are the rubber face, directly other other parts are fixed, and need not to add the rubber pad in addition, have saved sealing gasket, have made things convenient for assembly process.
