Abstract
The invention provides a novel oxygen valve anti-static device which is characterized in that an anti-rotating guide tube is mounted in a valve body center cavity of an oxygen valve; an anti-rotating guide rod is arranged in the position, corresponding to the anti-rotating guide tube, on a valve clack of the oxygen valve; the anti-rotating guide rod is inserted into the anti-rotating guide tube and can axially move up and down; a positioning guide rail is arranged on the other side, corresponding to the anti-rotating guide tube, in the valve body center cavity; a positioning groove is formed in the position, corresponding to the positioning guide rail, in the valve clack; and the valve clack can move along the positioning guide rail. The novel oxygen valve anti-static device is simple in structure and reasonable in design, can prevent the valve clack from rotating and swinging, and effectively guarantees the sealing performance and work safety of a high-temperature and high-pressure oxygen valve.
Description
Technical field
The present invention relates to a kind of anti-static device, relate 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 when sealing surface seals, and the relative turn of sealing surface produces the situation of static.
Summary of the invention
The problem to be solved in the present invention 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 used in the present invention 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, corresponding to described anti-rotation conduit place, be provided with an anti-rotation guide rod, described anti-rotation guide rod interts and can move axially up and down in described anti-rotation conduit, at the inner opposite side corresponding with described anti-rotation conduit of valve body lumen, be provided with positioning guide rail, 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 good effect that the present invention has are: oxygen valve anti-static device of the present invention, 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, avoided 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 invention will be further described.
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, corresponding to described anti-rotation conduit 2 places, be provided with an anti-rotation guide rod 4, described anti-rotation conduit 2 matches with described anti-rotation guide rod 4, and coordinate accurate, described anti-rotation guide rod 4 can only be done up and down and move axially in described anti-rotation conduit 2, at the inner opposite side corresponding with described anti-rotation conduit 2 of valve body 1 lumen, be provided with positioning guide rail 5, 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.
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, when 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 embodiments of the invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the scope of the invention and improvement etc., within all should still belonging to this patent covering scope.
