Description
Technical field
The utility model relates to a kind of anti-static device, relates in particular to a kind of novel oxygen valve anti-static device.
Background technique
High Temperature High Pressure oxygen medium belongs to inflammable and explosive dangerous goods, and High Temperature High Pressure oxygen pipeline and valve belong to the equipment of peak demand grade.Because the fundamental difference of oxygen and other media is, oxygen is combustion improver, the burning of oxygen without any need for other combustion improvers, particularly High Temperature High Pressure under oxygen can not run into any point Mars.Therefore, antistatic performance is the important guarantee of oxygen valve stable operation, particularly prevents in the time that sealing surface seals, and the relative turn of sealing surface produces the situation of static.
Summary of the invention
Problem to be solved in the utility model be to provide a kind of simple in structure, reasonable in design, can effectively guarantee the sealing of High Temperature High Pressure oxygen valve and the anti-static device of job security.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel oxygen valve anti-static device is provided, valve body lumen inside at described oxygen valve is provided with an anti-rotation conduit, on the flap of described oxygen valve, be provided with an anti-rotation guide rod corresponding to described anti-rotation conduit place, described anti-rotation guide rod interts and can move axially up and down in described anti-rotation conduit, be provided with positioning guide rail at the inner opposite side corresponding with described anti-rotation conduit of valve body lumen, on flap, be provided with locating slot with described positioning guide rail corresponding section, flap can move along positioning guide rail.
Described anti-rotation conduit is arranged on cavity wall upper end in described valve body, and described positioning guide rail is arranged on the offside lower end of described anti-rotation conduit in described valve body lumen.
Described flap is semicircle, has the boss of a trough of belt on flap straight flange, and described anti-rotation guide rod is arranged on a side of described boss, and described locating slot is arranged on the offside of the above anti-rotation guide rod of described flap.
Advantage and the good effect that the utlity model has are: oxygen valve anti-static device of the present utility model, anti-rotation guide rod is set and anti-rotation conduit matches, positioning guide rail and locating slot match, flap can only be moved up and down in valve body lumen, avoid flap to occur rotating and dancing, guaranteeing does not have phase mutual friction between valve body and sealing surface, can not produce static spark, thereby guarantee sealing and the Security of valve.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of novel oxygen valve anti-static device, valve body 1 lumen inside at described oxygen valve is provided with an anti-rotation conduit 2, on the flap 3 of described oxygen valve, be provided with an anti-rotation guide rod 4 corresponding to described anti-rotation conduit 2 places, described anti-rotation conduit 2 matches with described anti-rotation guide rod 4, and coordinate accurate, described anti-rotation guide rod 4 can only do up and down and move axially in described anti-rotation conduit 2, be provided with positioning guide rail 5 at the inner opposite side corresponding with described anti-rotation conduit 2 of valve body 1 lumen, on flap 3, be provided with locating slot 6 with described positioning guide rail 5 corresponding sections, described positioning guide rail 5 matches with described locating slot 6.
Anti-rotation conduit 2 is arranged on cavity wall upper end in described valve body 1, and described positioning guide rail 5 is arranged on the offside lower end of described anti-rotation conduit 2 in described valve body 1 lumen.
Flap 3 is semicircle, has the boss 8 of a trough of belt 7 on flap 3 straight flanges, and described groove 7 matches with the valve rod of oxygen valve, and anti-rotation guide rod 4 is arranged on a side of described boss 8, and described locating slot 6 is arranged on the offside of described flap 3 the above anti-rotation guide rod 4.
In use, anti-rotation guide rod 4 coordinates with anti-rotation conduit 2, positioning guide rail 5 matches with locating slot 6, flap 3 can move up and down to realize the opening and closing of valve under the effect of valve rod 9 in valve body 1 lumen, in the process moving at flap 3, anti-rotation guide rod 4 also moves up and down in anti-rotation conduit 2, in the time closing flap 3, flap 3 moves down, anti-rotation guide rod 4 is also along with flap 3 moves down, length of thread engagement between anti-rotation guide rod 4 and anti-rotation conduit 2 will reduce, flap 3 is easy to occur bowing or the dancing such as yaw on valve rod, thereby be not closed completely while causing throttle down, and positioning guide rail 5 and locating slot 6 coordinate, flap 3 moves along positioning guide rail 5, the amount that flap 3 is swung is controlled in very little certain limit, effectively guarantee the smooth and easy movement of flap 3 and good sealing.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the utility model scope, within all should still belonging to this patent covering scope.
