Description
Technical field: the utility model relates to the auxiliary device in pressure tube perforate operation in the operation of a kind of city gas pipeline dimension first-aid repair construction, particularly a kind of combination perforate rotary valve.
Background technique: existing steel burning line is relocated and tie up in first-aid repair construction all need to pipeline carry out perforate, equalizing main pressure and install blocking this three process; Auxiliary device used in this three process has perforate to connect case, sandwich valve, blind plate; The deficiency that this kind of auxiliary device in use exists is: 1, involved parts are many, need connect case, sandwich valve, blind plate three kinds of parts fulfil assignment with perforate; 2, operating efficiency is lower, because in operation process, needs repeatedly compensation flap to open and being dismounted for multiple times equipment again, tears open at every turn and fill and will expend many time, make operating efficiency lower; 3, Security is poor, because manipulating object is pressure piping, in pipe, the pressure of medium is comparatively large, in operation, standby because need repeatedly tearing open and install, thus the as easy as rolling off a log medium that causes leaks, and causes security incident to occur.
Summary of the invention: the purpose of this utility model is, carry out relocating and tie up the deficiency that in first-aid repair construction, its auxiliary device in use exists for existing steel burning line, and a kind of combination perforate rotary valve is proposed, it has the function that existing auxiliary device perforate connects case, sandwich valve, blind plate three, and without the need to repeated multiple times disassemblerassembler in operation process, make job safety with quick.
Can realize the purpose of this utility model by following technical proposals, a kind of combination perforate rotary valve, it is characterized in that, it comprises valve body, casing, rotating shaft, pressing plate, pressure gauge, balance diffusion valve, closure plate, screw rod; Rotating shaft one end is fixed on valve body, and casing is inserted in rotating shaft by the hole cover being located at its lower end surface; Pressing plate is fixed by screws in valve body upper-end surface, and a part for pressing plate covers the upper-end surface at casing edge; Casing is provided with trepanning device cavity; Pressure gauge and balance diffusion valve are located on casing; Closure plate is located in the depression of valve body, and screw rod passes through valve body and is connected with valve body spiral, and screw front end is inserted in the cavity of closure plate, screw rod Shang Taoyouban garden clamp.
For making good airproof performance, be provided with seal ring on cabinet end limit and valve body joining place; Seal ring is respectively equipped with in the upper-end surface of closure plate and side end face.
For making device stable in operation, pressing plate is provided with the positioning screwn positioned casing.
For making device and Flange joint fix, valve body is provided with the connecting bolt be connected with flanged fitting.
Effect of the present utility model is: 1, apparatus structure compact and reasonable, and it possesses the function that perforate connects case, sandwich valve, blind plate three kinds of parts; 2, operating efficiency is high, because in operation process, no longer needs repeatedly compensation flap to open and being dismounted for multiple times equipment again, after ending hole, only needs casing to horizontally rotate 180 °, with closure plate, trepanning device cavity is blocked sealing, just can diffuse medium; In engineering ending phase, " completion blocking " is installed in trepanning device main shaft lower end, and casing is horizontal rotation 180 ° again, blocks in flange plugging hole down, pulls down trepanning device and this device, builds blind plate, end-of-job; 3, Security is good, because in operation process, does not need to tear open and install standby, thus is not easy to cause medium to leak, make production safety reliable.
Accompanying drawing illustrates:
Accompanying drawing 1 is sectional structure schematic diagram of the present utility model;
Accompanying drawing 2 is plan structure schematic diagram of the present utility model;
Accompanying drawing 3 is the sectional structure schematic diagram of the utility model casing after horizontally rotating 180 °.
Below in conjunction with drawings and Examples, the utility model is set forth further:
Embodiment:
See accompanying drawing 1,2,3, a kind of combination perforate rotary valve, it forms primarily of valve body 1, casing 2, rotating shaft 3, pressing plate 4, pressure gauge 5, balance diffusion valve 6, closure plate 7, screw rod 8; Rotating shaft 3 one end is fixed on valve body 1, and casing 2 is inserted in rotating shaft 3 by the hole cover being located at its lower end surface, and casing 2 can horizontally rotate centered by rotating shaft 3; Pressing plate 4 is fixed on valve body 1 upper-end surface by screw 41, and a part for pressing plate 4 covers the upper-end surface at casing 2 edge; Casing 2 is provided with trepanning device cavity 21, and pressure gauge 5 and balance diffusion valve 6 are located on casing 2; Closure plate 7 is located in the depression of valve body 1, screw rod 8 passes through valve body 1 and is connected with valve body 1 spiral, screw rod 8 front end is inserted in the cavity of closure plate 7, closure plate 7 can rotate with screw rod 8 and advance, but self non rotating, screw rod 8 Shang Taoyouban garden clamp 13, half garden clamp 13 function is to prevent screw rod 8 from coming off from valve body 1.For making good airproof performance, be provided with seal ring 9 on casing 2 end limit and valve body 1 joining place; Seal ring 10 is respectively equipped with in the upper-end surface of closure plate 7 and side end face.For making device stable in operation, pressing plate 4 being provided with the positioning screwn 11 positioned casing 2, after casing 2 horizontally rotates 180, positioning screwn 11 pairs of casings 2 can being pressed and position, operation is stablized.For making device and Flange joint fix, valve body 1 is provided with the connecting bolt 12 be connected with flanged fitting.
Operation procedure of the present utility model is: casing 2 upper end is connected with trepanning device, and valve body 1 is connected with flanged fitting by bolt 12, and its trepanning device cavity 21 aligns with flanged pipe piece bores, and positioning screwn 11 is fastening.Operation trepanning device boring cutter carries out perforate to pipeline, and boring cutter to be taken in after opening in the trepanning device cavity 21 in casing 2 by hole.Positioning screwn 11 unclamps, and casing 2 horizontally rotates 180 ° and tightened by positioning screwn 11.It is relative with closure plate 7 that trepanning device cavity 21 goes to opposite side, pushes up, sealed on closure plate 7 by trepanning device cavity 21; Another cavity is connected with the pipe hole opened, and appliance 4 carries out pressure measurement and part 5 diffuses displacement work; After new pipeline section puts into operation, i.e. engineering ending phase, " completion blocking " is installed in trepanning device main shaft lower end, and casing 2 is horizontal rotation 180 ° again, blocks in flange plugging hole down, pulls down trepanning device and this device, builds blind plate, end-of-job.
