Description
Technical field
The utility model relates to a kind of safety interlocking mechanism of self-energized seal door-opening pressure vessel, belongs to the pressure vessel technology field that is used for building materials, chemical industry, light industry, weaving etc.
Background technique
Need to feed the working medium of certain pressure in the pressurized container work, goods in the container are handled, and door-opening pressure vessel is owing to easy to operate, so in each industrial field extensive use.Sealing configuration between the door closure of door-opening pressure vessel and the cylindrical shell end can be divided into positive drive type and self tightening two big classes, stipulate according to " safe technology of pressure vessel supervision rules " simultaneously, door-opening pressure vessel also must dispose safety interlock, to prevent the blast effective measures of accident of door-opening pressure vessel, safety interlock should be able to guarantee under any circumstance, quick operating valve does not close and puts in place, and pressure source can not enter when in container and the container pressure being arranged, and quick operating valve can't be opened.The positive drive type sealing configuration is to rely on the pretightening force of fastening pieces such as bolt to guarantee to have between door closure, seal ring and the cylindrical shell end certain contact pressure to reach sealing; Because after cylinder pressure increases, the distortion of bolt, door closure descends the contact pressure between seal ring and door closure, the cylindrical shell end, so the forced seal structure will have bigger bolt pretightening so that on seal ring, still have enough contact pressures to reach sealing after pressing liter.Self-fastening sealing structure mainly is made of a plurality of one-way valves, and seal ring is controlled by external pressure source, therefore after working pressure rises, contact pressure between the seal ring strengthens, working pressure is high more, and then sealability is reliable more, so self-energized seal is widely used in the quick operating valve container.
And safety interlock mainly is made of Decompression valves, cam briquetting and safe connecting rod, when door closure close put in place after, dead-man's handle is pulled 90 ° to horizontal position, this moment, the cam briquetting was stuck on the limiting board that is fixed on the door closure, Decompression valves cuts out, and can enter pressure state in the container.When container work finishes, can open door closure when pressure gauge is shown to zero-bit behind the steam discharge, pull open dead-man's handle to the vertical position this moment, and Decompression valves is opened thereupon, the vapour if still have a surplus in the container this moment will be discharged from Decompression valves.But because the seal arrangement and the safety interlock of pressurized container are two separate structures, need in the work to operate respectively according to the order of sequence, therefore exist the hidden danger of operate miss.
Summary of the invention
The purpose of this utility model provides a kind of door closure is sealed with safety interlock and organically combines as a whole the safety interlocking mechanism of easy to operate, reliable self-energized seal door-opening pressure vessel.
The utility model is that the technological scheme that achieves the above object is: a kind of safety interlocking mechanism of self-energized seal door-opening pressure vessel, comprise the seal ring that is installed in the cylindrical shell end seal groove, Decompression valves, the cam briquetting and the safe connecting rod that have dead-man's handle, the cam briquetting is connected with safe connecting rod, the spool of safe connecting rod and Decompression valves joins and opens and closes with the control spool, Decompression valves communicates with cylinder lumen, it is characterized in that: also have three-way diverter valve and linkage mechanism, one termination pressure source of described three-way diverter valve, the other end leads to atmosphere, an end communicates with air flue on being arranged on cylindrical shell again, and this air flue communicates with seal groove; Described linkage mechanism comprises first connecting rod and the second connecting rod that is hinged on the connecting rod shank two ends respectively, and first connecting rod is connected with safe connecting rod, and second connecting rod is connected with the operating grip of three-way diverter valve.
The utility model is by the sealed circuit of a three-way diverter valve control cylindrical shell, simple in structure, component are few, and the operating grip of three-way diverter valve is connected by the safe connecting rod of a linkage mechanism with the control Decompression valves, in the control Decompression valves,, make Sealing ring for container reach the state of seal operation or emptying work by the work of linkage mechanism control three-way diverter valve, guaranteed that seal ring in time withdraws, reached the function of quick-sealing and pressure release.The utility model can carry out the operation of sealed circuit operation and safety interlocking synchronously because the interlock performance is good, has avoided misoperation effectively, has improved the functional reliability of pressurized container greatly.
