Abstract

The utility model relates to a high performance butterfly valve fire resistive construction, including valve body, valve rod, valve block, the valve rod be located the valve body, be equipped with the sealing washer device between this valve body and valve rod, the upper and lower both ends of this sealing washer device are installed respectively and are pressed the cover, the sealing washer device by the second sealing washer that adopts graphite and carbon fiber to make, adopt the stainless steel to constitute with the sectional third sealing washer of graphite, valve block and valve body, interior clamp plate, outer ledge between adopt stainless steel fire prevention valve seat insert device, the beneficial effects of the utility model are that: fire prevention product sealing parts all changes graphite and carbon fiber into by original PTFE, and this kind of material still has fine sealing performance under the condition of high temperature, and redesign has also been carried out to the structure of structure and the disk seat of clamp plate simultaneously, guarantees the sealed effect of product through soft disk seat and the double sealing of disk seat of managing to do sth. With difficulty, make high performance fire prevention butterfly valve still have fine sealing performance under high temperature and high pressure environment.

Description

High-performance butterfly valve fire proof construction
Technical field
This utility model belongs to butterfly valve technical field, more particularly, to a kind of high-performance butterfly valve fire proof construction.
Background technology
High-performance butterfly valve can realize the switch of valve using the control mode such as handle, decelerator, air impeller.Logical Cross rotation valve rod to complete keying effect, form the sealing relationship of medium simultaneously between the sealing surface of valve block and valve seat, to ensure The sealing property of valve.When valve block opening angle is 20 °~75 °, flow is linear with opening angle, has the spy of throttling Property.In short, high-performance butterfly valve is to control 0~90 ° of valve block reciprocating rotating to open, to cut out or to adjust a kind of valve of rate-of flow Door.And high-performance butterfly valve is using double eccentric structures, it is effectively reduced valve block contact and abrasion, moment of torsion is low, service life is longer, In the environment of being applied to high pressure (as shown in Figure 1).
Conventional high-performance butterfly valve seal is mainly contacted with the sealing surface of valve block 3 by the valve seat insert 12 that material is PTFE Realize sealing (as shown in Figure 2), the first sealing ring 13 material at valve rod 2 is also PTFE (as shown in Figure 3), this sealing Mode can have good sealing effectiveness in the environment of high pressure, but effect is undesirable in an environment of high temperature, no fire-proof function.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art exists, and provides one kind under high temperature and high pressure environment Still there is the high-performance butterfly valve fire proof construction of good sealing property.
The purpose of this utility model to complete by following technical solution, including valve body, valve rod, valve block, described Valve rod is located in valve body, is provided with gasket set, the upper and lower ends of this gasket set are respectively mounted between this valve body and valve rod There is gland;Described gasket set adds stone by the second sealing ring made using graphite and carbon fibre materials, using rustless steel 3rd sealing ring composition of black section;Rustless steel fire prevention valve base sealing is adopted between described valve block and valve body, clip plate, outer plate Coil apparatus.
Preferably, described rustless steel fire prevention valve seat gasket set is by soft valve seat insert, hard valve seat insert structure Become, described soft valve seat insert is located between valve body and clip plate, described hard valve seat insert is located at clip plate and external pressure Between plate, the sealing surface of wherein soft valve seat insert, the inner side edge of hard valve seat insert and valve block is in close contact;Described soft valve It is placed with O-ring between seat sealing ring and clip plate.
Preferably, described soft valve seat insert and O-ring are made using graphite and carbon fibre materials.
The beneficial effects of the utility model are:Fire-proof product obturator all changes graphite into by original PTFE and carbon is fine Dimension material, this kind of material still has good sealing property in the event of high temperatures, the structure of the structure of pressing plate and valve seat simultaneously Redesigned, ensured the sealing effectiveness of product by the dual-seal of soft valve seat and hard valve seat;Make high-performance fire-resistant Butterfly valve still has good sealing property under high temperature and high pressure environment.
