Abstract
This utility model relates to a kind of integral type Fluorine-lined relief valve, including valve body, valve seat, flap, valve gap, valve rod, spring pressure setting device and corrugated tube.It is characterized in that: valve body uses integral structure, anti-corrosion lining it is respectively lined with in valve body snout cavity and outlet plenum, radially step it is shaped with in valve body snout cavity, valve seat lower end is pressed on the anti-corrosion lining of this radial direction step in plane, being shaped with annular dovetail slot in end face inside valve body suction flange installing hole, anti-corrosion lining extends to annular dovetail slot from valve body snout cavity；Valve seat periphery is installed a gland by screw thread, on the anti-corrosion lining planar annular that gland lower surface is pressed in outlet plenum, arranges sealing ring between gland top inner ring surface and valve seat periphery.It is anti-corrosion, and lining is installed reliable, firm, has the advantages such as low cost of manufacture, sealing reliability is good, decay resistance is reliable.
Description
Technical field
This utility model belongs to valve field, especially relates to a kind of Fluorine-lined relief valve.This utility model is suitable for
On the pressure vessel or pipeline of Korrosionsmedium.
Background technology
The valve body of existing Fluorine-lined formula relief valve is to use split-type structural, such as Patent No.
ZL201120301743.4, patent name is: liner type safety valve, the valve body of this liner type safety valve be divided into into
Mouth side valve body and outlet side valve body, at inlet side valve body and outlet side valve body liner anticorrosive plastic respectively.It lacks
Point is: inlet side valve body and outlet side valve body need to make respectively mould, and production cost is high, inlet side simultaneously
When valve body and outlet side valve body are installed, adding a leakage point easily leaked outside, sealing reliability is poor.
Summary of the invention
The purpose of this utility model is the defect existed for prior art, it is provided that a kind of valve body is integral type knot
Structure, production cost is low, the integral type Fluorine-lined relief valve that sealing reliability is good.
The technical solution of the utility model includes that valve body, valve seat, flap, valve gap, valve rod, spring pressure are adjusted
Device and corrugated tube, flap is installed in the middle of Disc holder lower surface, and corrugated tube upper end is installed on valve body and valve gap
Between, corrugated tube lower end is welded on the internal ring wall connecting ring, and the external annulus connecting ring is welded in the Disc holder back of the body
Face, spring pressure setting device is arranged on the valve rod of valve gap inner chamber, and top, valve rod lower end is contained in the Disc holder back side
In centre bore.It is characterized in that: valve body uses integral structure, serves as a contrast respectively in valve body snout cavity and outlet plenum
Having anti-corrosion lining, be shaped with radially step in valve body snout cavity, valve seat lower end is pressed on the resistance to of this radial direction step
On erosion lining in plane, in the end face inside valve body suction flange installing hole, it is shaped with annular dovetail slot, anti-corrosion
Lining extends to annular dovetail slot from valve body snout cavity；Valve seat periphery is installed a gland by screw thread, under gland
On the anti-corrosion lining planar annular that end face is pressed in outlet plenum, gland top inner ring surface and valve seat periphery it
Between sealing ring is set.
Preferably, arranging unlatching pressure-regulating device outside sealing surface of seat, this unlatching pressure-regulating device is by adjusting
Pitch circle, regulation screw composition, regulation screw is arranged in the screw mounting hole on valve body by nut, block,
Screw mounting hole inwall and outer face serve as a contrast anti-corrosion lining.
The utility model has the advantage of: valve body divides in using integral structure, valve body snout cavity and outlet plenum
Not being lined with anti-corrosion lining, the anti-corrosion lining in valve body snout cavity and outlet plenum is compressed peace by valve seat and gland respectively
Dress, makes anti-corrosion lining install reliable, firmly, has that low cost of manufacture, sealing reliability be good, corrosion resistance
Can reliably wait advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Integral type Fluorine-lined relief valve as shown in Figure 1, including valve body 1, valve seat 2, flap 5, valve gap 6,
