Abstract
The utility model relates to a glass plate level gauge failure safety protecting device, which comprises a protecting seat, a protecting stressed top, a sealing pad and a screw bolt nut, wherein the protecting seat comprises a base and an outer edge plate, the inner chamber of the base is larger than the outline of a level gauge structure, the height of the base is also larger than the height of the structure of the level gauge, the outer edge plate is hollowly sleeved on the upper side portion of the base and is fixed in a sealing and welding mode, a plurality of holes are uniformly arrangedon the periphery of the ring of the outer edge plate, the bottom of the base is welded with the outer wall of a container body, the outline of the protecting stressed top is the same with the outlineof the outer edge plate, a plurality of holes which correspond to the periphery of the outer edge plate are distributed on the protecting stressed top, a plurality of screw bolts are fixed by the nutafter penetrating through a plurality of holes which correspond to the protecting stressed top, a sealing pad which has the same plane shape with the outer edge plate and the outer side late. The device has the advantages that construction can be carried out during the operation of the device, the normal production is not affected, and the device is the urgent and effective processing method afterthe level gauge is broken.
Description
Technical field:
The utility model relates to glass plate level gauge inefficacy security facilities, and particularly field internal pressure pipeline, pressure vessels such as oil, chemical industry, medicine, power plant are used for the glass plate level gauge of liquid level indication.
Background technology:
Chemical Manufacture is as the special trade of national economy industrial circle, and the safety of its production technology is stood in the breach, and the liquid level meter is one of safety attachment of boilers such as various towers, jar, groove, pressure vessel, is used for the Level Detection of medium in the equipment.Under the new situation growing in electronics technology, digital former biography liquid level controlling technology such as magnetic levitation type liquid level meter begin to widely apply, but glass plate level gauge with its show on the spot, simple in structure, indication is directly perceived, economic and practical, advantages such as maintenance simple and convenient are installed still is extensive use of in industries such as chemical industry, oil, the glass plate material that the liquid level meter uses is Pyrex, maximum working pressure (MWP) 6.3Mpa, allowing medium temperature is 0～250 ℃, heat-resisting sudden turn of events temperature is 240 ℃, and Nonopaque type, reflective, three kinds of patterns of visual-mirror type are arranged.Because it is removable that the import and export mix of Nonopaque type and reflective gage glass is designed to, and when the liquid level meter breaks, do not stop and can keep in repair and change the liquid level meter midway.And the structure of visual-mirror type glass plate level gauge is for embedding connecting-type, the edge that connects that is the liquid level meter directly is welded on the apparatus casing and (sees the glass plate level gauge structural drawing), the liquid level meter directly contacts with liquid, drastic change of liquid body high and low temperature and liquid property influence, existence is washed away, corrosion phenomenon, therefore when the liquid level meter breaks, could change the liquid level meter after needing to stop production immediately, bring very big inconvenience and loss for production and operation.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, the safety device that provides a kind of glass plate level gauge to lose efficacy.
Scheme of the present utility model is: device is made up of anti-guard housing, protection gland, sealing gasket, bolt and nut, anti-guard housing is made of pedestal and outer plate, base shape is tubulose or hollow, rectangular body, the pedestal inner chamber is greater than liquid level meter structure gabarit, base height is also greater than liquid level meter structure height, outer plate hollow space geometric configuration is identical with the pedestal gabarit, and plate hollow sleeve seal welding after the part of pedestal upper edge in outer is fixed, the uniform several holes of outer plate ring periphery; After pedestal is inserted in liquid level meter structure periphery, its bottom and tankage body outer wall seal welding; The protection gland is solid flat board, gabarit is identical with outer plate gabarit, protection is distributed with and the corresponding each other several holes of outer plate ring periphery on the gland, and several bolts are fixed with nut after passing and protecting gland, the several holes corresponding with sealing gasket, the outer plate three of the same flat shape of outer plate.
Advantage of the present utility model is: simple in structure, can design corresponding pattern according to the contour structures of liquid level meter, and can when equipment operation, construct, do not influence ordinary production, be urgent effectively disposal route after the liquid level meter breaks.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
Structure of the present utility model is made up of anti-guard housing (3), protection gland (5), sealing gasket (4), bolt and nut, anti-guard housing (3) is made of pedestal and outer plate (6), base shape is tubulose or hollow, rectangular body, the pedestal inner chamber is greater than liquid level meter structure (2) gabarit, base height also greater than liquid level meter structure (2) highly, outer plate (6) hollow space geometric configuration is identical with the pedestal gabarit, outer plate (6) hollow sleeve seal welding after the part of pedestal upper edge is fixed, the peripheral uniform several holes of outer plate (6) ring; After pedestal is inserted in liquid level meter structure (2) periphery, its bottom and tankage body (1) outer wall seal welding; Protection gland (5) is solid flat board, gabarit is identical with outer plate (6) gabarit, be distributed with in protection gland (5) and the corresponding each other several holes of outer plate (6) ring periphery, several bolts pass protection gland (5), fix with nut behind the corresponding several holes of sealing gasket (4), outer plate (6) three of flat shape equally with outer plate (6).
The device profile can be according to liquid level meter structure (2) size design, a kind of is to use solid drawn tube and flange assembly welding as anti-guard housing (3), blind flange is protection gland (5), another kind be with the square edge that connects as anti-guard housing (3), with solid drawn tube partly cut open with square flange assembly welding be Long Circle protection gland (5).Anti-guard housing (3) is welded on device outer surface in advance, find that will protect gland (5) with bolt, nut when the liquid level meter breaks locks on anti-guard housing (3), blindly fall the liquid level meter is temporary transient, Parking permitted for device to be produced when changing, take gland apart, the liquid level meter that replacing is broken recovers its normal liquid level indicative function.
Should be when anti-guard housing (3) of design and gland according to the condition of work of equipment, the corrosivity, working pressure, temperature that are medium are selected other flange of relevant pressure level, blind flange, pad, securing member and suitable material, use squarely to tackle its intensity when connecing edge and carry out verification.
