Description
Technical field
This utility model relates to valve field, especially relates to fill in one Fixed ball valve.
Background technology
Upper-mounting type ball valve is made up of valve body, spheroid, valve gap, valve seat, valve rod, drive mechanism (such as turbine box), and valve body is one
Body structure, spheroid is installed to downwards body cavity at valve gap and coordinates with valve base sealing.Such as Chinese patent
ZL201110067828.5 discloses dress formula fixing ball valve, including valve body, spheroid, valve gap, valve seat, valve rod, drive mechanism,
Sealing member and installed part, valve body is integral type structure.
At present, the valve seat of upper dress Fixed ball valve is the most all metal seat valve, and the sealing between itself and spheroid and valve body is all
It is the soft seal form by sealing ring etc., when situations such as breaking out of fires, due to the expansion system of metal seat valve etc. with sealing ring
The difference of number, causes the sealing property between metal seat valve and spheroid bad, it will usually to leak.
Additionally, valve seat and the maintenance of spheroid and replacing for convenience, the most external upper-mounting type ball valve produced, valve seat is led to
Crossing an adjustment circle to be installed at valve gap in valve channel, the inside and outside disc adjusting circle is formed respectively with female thread and external screw thread, its
Female thread is connected with valve seat threaded engagement, and external screw thread is connected with body cavity wall threaded engagement, and adjusting circle can be at body cavity
Mobile regulation on wall, makes seat compression ball seal coordinate or departs from spheroid realize maintenance and change, and its shortcoming is: valve seat passes through
Adjusting circle by being threadably mounted in valve body, in use, be connected for being screwed between valve seat with valve body, valve seat can not be
Float in valve body, when high-temperature medium operating mode uses, between valve seat and spheroid easily expansion and stuck.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide dress in one fixing
Formula ball valve.
The purpose of this utility model can be achieved through the following technical solutions:
Fixed ball valve is filled, including valve body, spheroid, valve gap, valve seat and valve rod, between described valve seat and spheroid in one
Contact and formed sealing surface, between described valve seat and valve body, be additionally provided with spring plenum length, be provided with in cavity and prop up valve seat and make
The spring unit of sealing it is in close contact between valve seat and spheroid；
It is additionally provided with the greasing hole connecting spring plenum length on described valve body, valve seat is additionally provided with connection spring plenum length with close
The discharge orifice of front cover.When emergency situations such as breaking out of fires, the sealing surface between valve seat and spheroid can be deteriorated, now, and valve seat
Can automatic paste tightening spheroid, the leakage between reduction valve seat and spheroid under the effect of spring unit；At the same time it can also be by outside
Inject the formation of sealant successively through greasing hole, spring plenum length and discharge orifice, then penetrate into sealing surface, it is achieved close under emergency situations
Envelope.Sealant can be M810 molybdenum bisuphide, grease SS5, FG203, F208.
It is provided with valve seat supporting between described valve seat and valve body, between the supporting of this valve seat and valve seat, forms spring plenum length.Logical
Crossing the setting of valve seat supporting, reducing spring unit needs the weight of the valve seat promoted, it is simple to simplifies spring structure, and saves valve seat
Material.
Form filler cavity between described valve gap top and valve rod, in this filler cavity, be filled with fire-proof packing, anti-
Fire filler is also arranged above gland.The filling of the fire-proof packing at valve gap top, coordinate gland and valve rod and valve gap it
Between sealing ring, can effectively prevent reveal anticorrosion.
Described gland is contacted with valve rod and valve bonnet seal by a sealing ring respectively.
Described fire-proof packing is soft graphite.
Described valve rod is connected with between spheroid and valve gap by an annular steel ball structure the most respectively.Annular steel ball structure
Arrange can effectively by spheroid because electrostatic fricative between valve seat conducts.
Described annular steel ball structure is spaced to circulate to be connected by multiple steel balls and sub-spring and forms.Steel ball and spring composition
Annular steel ball structure can not only ensure to have between valve rod and valve seat, spheroid enough contacts area, moreover it is possible to limited saving steel ball
Consumption.
A sealed nylon circle it is additionally provided with between described valve seat and spheroid.
Compared with prior art, this utility model has the advantage that
(1) valve rod and the setting of fire-proof packing in the filler cavity at valve gap top, the spring unit between valve seat and valve body,
And the setting of the orifice structure on the greasing hole on valve body and valve seat, can be when when emergency situations such as breaking out of fires, it is ensured that
The sealing of effective whole valve is not revealed.
(2) setting of the annular steel column structure on valve rod, so that valve rod can be effectively by fricative for valve body quiet
Electric charge is derived by valve gap etc. timely, it is to avoid a large amount of accumulation of static electricity and the disaster that produces.
(3) simple in construction, seals classification other, when at nominal conditions, valve seat fitted seal circle is in the effect of spring unit
Under can realize sealing, when emergency situations such as breaking out of fires, sealant can be injected in time by outside, penetrate into sealing surface,
Ensure to seal and do not reveal.
