Abstract
The utility model discloses a waterproof valve position indicator. The waterproof valve position indicator comprises a box cover, a dial marked with scale marks and a seal ring, as well as a pressure ring and a glass window, wherein the pressure ring is used for sequentially fixing the glass window, the seal ring and the dial on the box cover; and the waterproof valve position indicator further comprises a pointer fixed on a worm wheel, and the pointer is positioned between the glass window and the dial. The valve position indicator with the structure can thoroughly solve the water inlet problem of a box body and a valve rod part, be directviewing and clear to indicate the valve position, prolong the service life of a valve and ensure the safety of petroleum and natural gas pipelines.
Description
Technical field
The utility model relates to a kind of indicator that is used for valve part device for revolving and driving position, especially a kind of valve phase indicator of waterproof.
Background technique
Valve phase indicator is a kind ofly to be used to indicate valve portion to divide the instrument of device for revolving and driving position, uses the direction board indication valve position that is fixed on the worm gear usually.Rely on O-ring seals to seal between worm gear and the case lid.
Because valve much is mounted in field, the open-air atmosphere, exposes to the sun and rain for a long time.Owing to processing, tolerance reason movingly; Between worm gear and case lid, there is certain clearance; The long-term contact with air of O-ring seals worn out, O type circle water-tight no longer behind the certain hour, and rainwater corrodes inner body through the entering casing of the gap between worm gear and the case lid; Inner body can not normally be used, cause the valve can not normal switch; Rainwater gets into the worm gear endoporus with part valve rod, key, sealing ring, O-ring seals corrosion through the elongated slot and the gap between the worm gear of worm gear switch direction board fixing screw; Also can cause the valve can not normal switch; Even leak, bring potential safety hazard for oil, natural gas line.
The model utility content
To the technical problem of above-mentioned existence, the utility model provides a kind of waterproof valve phase indicator, can prevent effectively that sealing gets into valve inner through slit between valve gap and the worm gear and the slit between screw and the worm gear.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of waterproof valve phase indicator comprises case lid, indicates dial, the seal ring of scale, it is characterized in that: also comprise trim ring, windshield; Described trim ring is fixed on windshield, seal ring and dial on the case lid successively; Also comprise the pointer that is fixed on the worm gear, described pointer is between windshield and dial.
As a kind of improvement, also comprise fixed tray, double-screw bolt, nut; Said fixed tray is fixed on the worm gear; Pointer is fixed on the double-screw bolt; Said double-screw bolt utilizes nut to be fixed on the fixed tray.
As a kind of preferred, described windshield is an emissive plastic glazing.
The usefulness of the utility model is:
Valve phase indicator with said structure can thoroughly solve the water inlet of casing, valve rod position, the valve position indication is simple and clear, has prolonged valve working life, has guaranteed oil, natural gas line safety.Utilize double-screw bolt and nut and fixed tray that pointer is fixed on the worm gear, can conveniently regulate pointer position up and down.Emissive plastic glazing is difficult for broken.
Description of drawings

Fig. 2 is the plan view of the utility model waterproof valve phase indicator.
Mark among the figure: 1. trim ring, 2. windshield, 3. pointer, 4. double-screw bolt, 5. screw, 6. fixed tray, 7. dial, 8. seal ring, 9. screw, 10. nut, 11. worm gears, 12. screws, 13. case lids.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1-2:
The utility model comprises dial 7, the seal ring 8 that indicates scale, it is characterized in that: also comprise trim ring 1, windshield 2; Described trim ring 1 is fixed on windshield 2, seal ring 8 and dial 7 on the case lid 13 successively; Also comprise the pointer 3 that is fixed on the worm gear 11, described pointer 3 is between windshield 2 and dial 7.
Can utilize fixed tray 6 that pointer 3 is fixed on the worm gear 11.Fixed tray 6 utilizes screw 12 to be fixed on the worm gear 11; Pointer 3 utilizes screw 5 to be fixed on the double-screw bolt 4; Said double-screw bolt 4 utilizes nut 10 to be fixed on the fixed tray 6.Windshield 2 is preferably emissive plastic glazing.
Cooperate sign valve position that can be clear and definite when using through the scale on pointer 3 and the dial 7.Seal ring 8 cylindricals and case lid 13, seal ring 8 planes and windshield 2 and dial 7 static seal waterproof make rainwater can not get into box house, can not get into worm gear 11 endoporus again, thoroughly are isolated from the outside, and have reached the purpose of water-tight
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
