The self-closing valve assembly that can automatically close, it is characterised in that on the inlet end port inner wall of described valve body, there is female thread one,
The inlet end fixed cover of valve body is provided with the clamping cap of tubular, is circumferentially with between described clamping cap inwall and valve body inlet end end face
Soft graphite one, described pipe gas blocked valve also includes adjustable joint, and one end of described adjustable joint is relative with the outlet side of valve body,
And between adjustable joint and the outlet side of valve body by nut lock fastening even, the outlet side end face of described adjustable joint end face and valve body it
Between be circumferentially with soft graphite two.
During installation connect air feed equipment air inlet Gas Pipe be plugged in the inlet end of valve body, and with valve body inlet end inwall
Threaded engagement, the Gas Pipe of giving vent to anger connecting gas meter, flow meter and gas-fired equipment is then plugged in adjustable joint, and seals connected with adjustable joint,
Self-closing valve assembly is a kind of parts that can automatically close when environment temperature reaches setting value, in utility model patent (application
Number: 201520906500.1) have disclosed, soft graphite one is positioned at clamping cap inwall, air inlet Gas Pipe outer wall and valve body and enters
Between gas end end face, after clamping cap screws soft graphite one can be pressed on clamping cap inwall, air inlet Gas Pipe outer wall and
On valve body inlet end end face, play sealing function, soft graphite two between valve body outlet side end face and adjustable joint end face, when
When nut screws, soft graphite two can be pressed on valve body outlet side end face, adjustable joint end face and nut inwall, plays close
Envelope effect, wherein soft graphite has performance the most high temperature resistant, pressure, therefore when burst accidents such as breaking out of fires around temperature
Degree raises, and self-closing valve assembly can cut off gas pipeline, and the high-temperature stability of soft graphite is it can be avoided that soft graphite one He
Soft graphite two lost efficacy, and still has stable sealing effectiveness, therefore seals stability more preferable, and safety is higher.
In above-mentioned pipe gas blocked valve, logical between one end inwall and the inlet end outer wall of valve body of described clamping cap
Crossing threaded, on the other end inwall of described clamping cap, circumference has the compression convex edge of annular, and described soft graphite one is positioned at
Between inlet end end face and the compression convex edge of valve body, compress convex edge when clamping cap screws and be pressed on soft graphite one.Compress
Cap and valve body inlet end threaded engagement, therefore compressing convex edge when clamping cap screws can be near valve body inlet end end face so that
Soft graphite one between the two is extruded, and the soft graphite one being squeezed can expanded radially, i.e. soft graphite one difference
It is pressed on the inwall of clamping cap and the outer wall of air inlet Gas Pipe, thus to valve body inlet end, clamping cap and gas inlet pipe
Between seal.
In above-mentioned pipe gas blocked valve, one end of described nut is set in the outlet side of valve body, and nut is interior
Being threaded connection between the outlet side outer wall of wall and valve body, on the other end inwall of described nut, circumference has the connection of annular
Convex edge one, one end of described adjustable joint is inserted in nut, and circumference has the connection convex edge of annular on one end outer wall stretched into
Two, described connection convex edge two is resisted against on the inner face connecting convex edge one.The connection convex edge one of nut is buckled on adjustable joint, screws
During nut, the convex edge one that connects of nut is pressed on the connection convex edge two of adjustable joint so that adjustable joint end face is to valve body outlet side end
Face is close, and soft graphite two between the two is extruded, soft graphite two expanded radially under extruding force, and its outer ring can compress
On nut inwall, thus seal between adjustable joint, nut and valve body outlet side.
In above-mentioned pipe gas blocked valve, described adjustable joint stretches into also has propping up of tubular on one end end face of nut
Support part, described supporting part stretches in the outlet side port of valve body, and described soft graphite two is set on supporting part, when nut screws
Time valve body the face clamping of outlet side end face and adjustable joint on soft graphite two, and soft graphite two is pressed on outside supporting part
On wall and nut inwall.Soft graphite two is carried out radially supporting by supporting part so that inner ring when soft graphite two is extruded expansion
Can be pressed on supporting part outer wall, not only increase sealing area, and the structure of soft graphite two is more stable.
In above-mentioned pipe gas blocked valve, on the port outer wall of described supporting part, circumference has the limit convex of annular
Edge, described soft graphite two is between the end face and limit convex edge of adjustable joint.Limit convex is along the inner ring of two pairs of soft graphites two
Carrying out restriction in shape, it is to avoid soft graphite two transition deformation causes sealing to decline, soft graphite two also is able to pressure simultaneously
Tight on the end face on limit convex edge, add sealing area.
In above-mentioned pipe gas blocked valve, the inwall of described adjustable joint has female thread two.Adjustable joint with give vent to anger
Gas Pipe is attached by screw thread, i.e. can lock Gas Pipe of giving vent to anger, easy accessibility by rotation adjustable joint.
Compared with prior art, this pipe gas blocked valve has the advantage that
1, due to soft graphite, there is performance the most high temperature resistant, pressure, the therefore week when burst accidents such as breaking out of fires
Enclosing temperature to raise, self-closing valve assembly can cut off gas pipeline, and the high-temperature stability of soft graphite is it can be avoided that soft graphite
One and soft graphite two lost efficacy, still there is stable sealing effectiveness, therefore seal stability more preferable, safety is higher.
