Abstract
The invention discloses an antitheft pressure tapping device. The antitheft pressure tapping device is characterized in that an antitheft pressure tapping device body formed by combining permanent magnet codes and mechanical codes is additionally arranged on a valve deck of a needle valve formed by a valve rod, a needle valve rod, the valve deck and a sealing cover, a supporting ring is additionally arranged on the portion, at the top of the needle valve rod, of the antitheft device, inner magnetic steel is embedded into the supporting ring, the supporting ring is fixed to the needle valve rod through a bolt, a shielding cover with a groove engraved in the bottom outer circle is installed on the valve deck and a boss on the upper portion of the valve body, outer magnetic steel is embedded into the upper end in a special coding outer sleeve, a movable ring with a convex groove formed in the inner circle is installed at the lower end in the special coding outer sleeve, a check block is fixed to the bottom of the special coding sleeve, the inner magnetic steel and the outer magnetic steel are combined and ranked through the radial mechanical codes, and the groove in the bottom of the shielding cover and the convex groove of the movable ring are combined and ranked through the radial mechanical codes. The antitheft pressure tapping device has the advantages that the antitheft function is achieved, and potential safety hazards are completely eradicated.
Description
Technical field
The present invention relates to a kind of antitheft pressure obtaning device.
Background technique
In the prior art, petroleum industry, for being located in the remote and numerous unattended oil production field disperseed again, the crude oil pipeline of exploitation being installed conventional needle value pressure and be there is drawback and the potential safety hazard that this place's pressure gauge was often stolen and stole crude oil.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the antitheft pressure obtaning device providing a kind of practicality, has antitheft and stops the feature of potential safety hazard.
For reaching above-described object, the antitheft pressure obtaning device of one of the present invention takes following technological scheme:
A kind of antitheft pressure obtaning device, it is characterized in that, antitheft pressure obtaning device is made up of with mechanical coding permanent magnetism coding a set of, and be installed at valve body, aciculiform valve rod, valve gap and sealing cover form on the valve gap of needle value, anti-theft device installs supporting ring additional with magnet steel in setting-in at aciculiform valve stem top, supporting ring is bolted on aciculiform valve rod, on the cylindrical of bottom, notched radome is installed on the boss on valve gap and valve body top, own coding outer sleeve inner upper end is embedded with outer steel, its lower end is provided with the rotating ring that inner circle is tongue, block is fixed on own coding sleeve bottom, interior magnet steel and outer steel, barrier cover bottom groove and rotating ring tongue adopt radial mechanical coding assembled arrangement.
Adopt the present invention of as above technological scheme, there is following beneficial effect:
Only have scene to be authorized librarian use own coding sleeve and could open pressure measuring valve, thus reach antitheft effect, avoid potential safety hazard.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, the antitheft pressure obtaning device of one of the present invention, by valve body 1, aciculiform valve rod 3, valve gap 4 and sealing cover 9 form needle value, adjustment packing ring 5 and seal ring 2 ensure that zero leaks outside, valve gap 4 install additional a set of by the anti-theft device that permanent magnetism is encoded and mechanical coding is combined, this anti-theft device installs supporting ring 12 additional with magnet steel in setting-in 11 at aciculiform valve rod 3 top, supporting ring 12 is fixed on aciculiform valve rod 3 by bolt 14, on the cylindrical of bottom, notched radome 8 is installed on valve gap 4, own coding sleeve 13 inner upper end is embedded with outer steel 10, its lower end is provided with the rotating ring 7 that inner circle is tongue, block 6 is fixed on bottom own coding sleeve 13, interior magnet steel 11 adopts radial coded combination to arrange with outer steel 10, the tongue of barrier cover 8 bottom groove and rotating ring 7 also adopts radial mechanical coding assembled arrangement.After during on-the-spot pressure, the own coding sleeve 13 of this check mark is inserted in radome 8 by the personnel that are only authorized, rotate counterclockwise own coding sleeve 13 and just can open pressure, this needle value is closed tight and preservation taken away by own coding sleeve 13 at ordinary times, thus reaches antitheft effect, avoids potential safety hazard.
