Abstract
The utility model provides a permanent magnet zero-leakage pressure tapping mechanism capable of preventing petroleum from burglary, which solves the problems that pressure meters are stolen frequently and crude oil is stolen in the prior art, and is characterized in that: a set of anti-theft device in the combination of permanent magnet encoding and mechanical encoding is arranged on a valve cover 4 of a needle valve comprising a valve body 1, a needle valve rod 3, the valve cover 4 and a sealing cover 9; a support ring 12 is arranged at the top of the needle valve rod 3, so as to embed an inner magnetic steel 11; the support ring 12 is fixed on the needle valve rod 3 through a bolt 14; a screening cover 8 provided with a concave groove on an external circle of the bottom is installed on the valve cover 4; an outer magnet steel 10 is arranged at the upper end of the inner part of a special encoding sleeve 13 in an embedded manner; a moving ring 7 with an internal circle of a convex groove is installed at the lower end of the inner part of the special encoding sleeve; a retaining block 6 is fixed at the bottom of the special encoding sleeve 13; and the inner magnet steel 11 and the outer magnet steel 10 as well as the concave groove at the bottom of the shielding cover 8 and the convex groove of the moving ring 7 are arranged by adopting radial mechanical encoded combination. The permanent magnet zero-leakage pressure tapping mechanism has the beneficial effect of anti-theft, and avoids potential safety hazard.
Description
Technical field
The zero antitheft pressure of the oil mechanism that leaks outside of a kind of permanent magnetism, being used for petroleum industry and other industrial facility line transportation needs occasions such as antitheft pressure, belongs to the fluid machinery technical field.
Background technique
In the prior art, petroleum industry is installed conventional needle value pressure and is existed this place's pressure gauge often to be stolen and steal the drawback and the potential safety hazard of crude oil at being located in numerous unattended oil recovery well site remote and that disperse again on the crude oil pipeline of exploitation.
Summary of the invention
The utility model purpose is at the deficiencies in the prior art, and a kind of permanent magnetism zero antitheft pressure of oil mechanism that leaks outside is provided, and this permanent magnetism zero antitheft pressure of oil mechanism that leaks outside has antitheft and stops the characteristics of potential safety hazard.
The technological scheme that the utility model is taked is: the zero antitheft pressure of the oil mechanism that leaks outside of a kind of permanent magnetism, it is characterized in that: at valve body 1, aciculiform valve rod 3, install a cover additional by permanent magnetism coding and the combined anti-theft device of mechanical coding on the valve gap 4 of valve gap 4 and sealing cover 9 formation needle values, this anti-theft device aciculiform valve rod 3 tops install additional supporting ring 12 with setting-in in magnet steel 11, supporting ring 12 is fixed on the aciculiform valve rod 3 by bolt 14, notched radome 8 is installed on the valve gap 4 on the cylindrical of bottom, own coding sleeve 13 inner upper end are embedded with outer steel 10, circle was the rotating ring 7 of tongue in its lower end was equipped with, block 6 is fixed on own coding sleeve 13 bottoms, interior magnet steel 11 and outer steel 10, barrier cover 8 bottom grooves and rotating ring 7 tongues adopt radially mechanical coding assembled arrangement.
Described barrier cover 8 is installed on the boss on valve body 1 top.
The beneficial effects of the utility model are: the zero antitheft pressure obtaning device of oil that leaks outside of this permanent magnetism has only the scene personnel of being authorized to use the own coding sleeve could open pressure measuring valve, thereby reaches antitheft effect, has avoided potential safety hazard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1, valve body; 2, seal ring; 3, aciculiform valve rod; 4, valve gap; 5, adjust packing ring; 6, block; 7, rotating ring; 8, radome; 9, sealing cover; 10, outer steel; 11, interior magnet steel; 12, supporting ring; 13, own coding sleeve; 14, bolt.
Embodiment
Provide embodiment of the present utility model below in conjunction with Fig. 1: the utility model constitutes needle value by valve body 1, aciculiform valve rod 3, valve gap 4 and sealing cover 9, adjusts packing ring 5 and seal ring 2 and guarantees that zero leaks outside.On valve gap 4, install a cover additional by permanent magnetism coding and the combined anti-theft device of mechanical coding, this anti-theft device aciculiform valve rod 3 tops install additional supporting ring 12 with setting-in in magnet steel 11, supporting ring 12 is fixed on the aciculiform valve rod 3 by bolt 14, notched radome 8 is installed on the valve gap 4 on the cylindrical of bottom, own coding sleeve 13 inner upper end are embedded with outer steel 10, circle was the rotating ring 7 of tongue in its lower end was equipped with, block 6 is fixed on own coding sleeve 13 bottoms, interior magnet steel 11 adopts radially coded combination arrangement with outer steel 10, and the tongue of barrier cover 8 bottom grooves and rotating ring 7 also adopts radially mechanical coding assembled arrangement.After only the own coding sleeve 13 that will check the number of the personnel of being authorized is inserted in radome 8 during on-the-spot pressure, rotate counterclockwise own coding sleeve 13 and just can open pressure, this needle value is closed tight and own coding sleeve 13 is to take preservation away at ordinary times, thereby reaches antitheft effect, has avoided potential safety hazard.
