Abstract

The utility model relates to a melt cryogenic valve composed of an aqueous vapor inlet connecting pipe, an air inlet connecting pipe, an air outlet connecting pipe, a jacket pipe, an inner connecting pipe, an outer sleeve, a middle jacket, a valve core and the like. The aqueous vapor inlet connecting pipe and the air inlet connecting pipe are integrated through welding and connected with the inner connecting pipe through a thread, the inner connecting pipe is integrated with the middle jacket through welding, the middle jacket is sleeved on the outer circle of the valve core and can slide freely, the outer sleeve is welded with the valve core and the jacket pipe, and the air outlet connecting pipe and the jacket pipe are welded to form a compressed air outlet channel. The melt cryogenic valve has the advantages that the operation is simple and maintenance is not needed during usage.

Description

A kind of melt freezing valve
Technical field
The utility model relates to the melt freezing valve in a kind of melt pipe in the manifold of chemical fibre field.
Background technique
In the spinning equipment manifold, different customer requirements has nothing in common with each other to the melt mode of closing in the melt pipe in the manifold before the chemical fibre spinning at present, and traditional valve generally adopts valve rod; Valve rod has a cover mechanical seal device outward; With spanner valve rod is compressed the purpose of closing melt to reach in the time of need closing, because the melt spinning temperature reaches 270 ℃, the valve rod easy deformation; Seal ring is damage easily also, often needs maintenance and influence production.Because ambient temperature is high, so the working strength of workman in maintenance process is also very big.
Summary of the invention
The purpose of the utility model provides a kind of melt freezing valve, and this freezing valve is simple to operate, and using process need not maintenance.
The technological scheme of the utility model is achieved in that steam entrance sleeve and air intlet adapter are welded as a whole, and are connected with inner connecting tube through screw thread; The weldering of inner connecting tube and middle chuck is one, and the therebetween cover is enclosed within on the cylindrical of spool and can be free to slide, and overcoat and spool are welded as a whole, and jacket pipe and overcoat welding, air outlet slit are taken over jacket pipe and welded formation compressed air outlet passage.Temperature is that the melt about 270 ℃ flows in two smaller part circular holes in the middle of the spool; Melt is mobile very good when 270 ℃ of temperature, and pressurized air is taken over from air intlet and got into, and water gets into from the steam entrance sleeve; Be mixed into gas-vapor mix and flow into the inner chamber between therebetween cover and the spool at a high speed through inner connecting tube; Dividing plate and fin are arranged on the cylindrical of spool, and dividing plate and fin make air-flow get into the right side of inner chamber from the left downside of inner chamber through the aperture of spool, get into the upper left side of inner chamber again through the aperture of spool from the upper right side of inner chamber; Get into the space between overcoat and the middle chuck through the hole that therebetween puts again; After jacket pipe and air outlet slit are taken over flows out, make spool and inner melt fast cooling cooling like this, melt solidifying and play the effect of closing by melt.
