Abstract
The invention discloses a soft seal butterfly valve. The soft seal butterfly valve comprises a valve body and a valve rod; the position between the valve rod and the valve body is filled with graphite packing, a packing gland is pressed on the graphite packing, and a valve plate is fixedly connected to the lower end of the valve rod; and a valve plate sealing ring is pressed on the side wall of the valve plate through a valve plate pressing ring, and the valve plate sealing ring is in sealing fit with an inner cavity of the valve body. According to the soft seal butterfly valve, the valve plate sealing ring and the valve body are used for achieving soft seal contact, opening and closing are convenient and rapid, labor is saved, the fluid resistance is small, frequent operation can be carried out, and installation is convenient.
Description
Technical field
The present invention relates to valve class field, particularly belong to a kind of soft sealing butterfly valve.
Background technology
Butterfly valve refers to that closure member (flap or butterfly plate) is disk, rotates a kind of valve reaching to open and close around valve shaft, acts primarily as cut-out and throttling action on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, and in valve body, the axis around himself rotates, thus reaches to open and close or the purpose of regulation.Butterfly valve carries on the pipeline of various corrosivity, non-corrosive fluids medium be applicable to the engineering systems such as producer, coal gas, natural gas, liquefied petroleum gas, town gas, air, chemical industry smelting and generation environment-friendly, for regulating and block the flowing of medium.
Summary of the invention
It is an object of the invention to provide a kind of soft sealing butterfly valve, conveniently opening and closing is rapid, laborsaving, fluid resistance is little, can often operate, easy for installation.
Technical scheme is as follows:
A kind of soft sealing butterfly valve, includes valve body, valve rod, is filled with graphite packing between valve rod and valve body, in graphite packing, pressure is equipped with gland, valve rod lower end is fixedly connected with valve plate, and valve plate sealing ring is pressed on valve plate sidewall by valve plate trim ring, and valve plate sealing ring seals with body cavity and coordinates.
Couple between described valve plate trim ring, valve plate sealing ring, valve plate and have screw.
It is connected between described gland with valve body upper surface and has filler bolt.
The present invention realizes soft being in sealing contact by valve plate sealing ring and valve body, and conveniently opening and closing is rapid, laborsaving, fluid resistance is little, can often operate, easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
See accompanying drawing, a kind of soft sealing butterfly valve, include valve body 1, valve rod 2, graphite packing 3 it is filled with between valve rod 2 and valve body 1, in graphite packing 3, pressure is equipped with gland 4, valve rod 2 lower end is fixedly connected with valve plate 5, and valve plate sealing ring 7 is pressed on valve plate 5 sidewall by valve plate trim ring 6, and valve plate sealing ring 7 coordinates with valve body 1 bore seal.Couple between valve plate trim ring 6, valve plate sealing ring 7, valve plate 5 and have screw 8.It is connected between gland 4 with valve body 1 upper surface and has filler bolt 9.
