Chemical Industry Standard of the People's Republic of China HG/T2433--93 Glass Liquid Level Gauge Issued on June 14, 1993 Implementation on January 1, 1994 Issued by the Ministry of Chemical Industry of the People's Republic of China Chemical Industry Standard of the People's Republic of China Glass Liquid Level Gauge 1 Subject content and scope of application HG/T2433-93 This standard specifies the type, basic parameters, main dimensions and technical requirements of portable glass liquid level gauges. This standard applies to the liquid level indication of sugar glass containers for chemical, petroleum and other industries with a nominal pressure in the container less than or equal to 0.6MPa and a medium temperature of 0C to 150℃. 2 Reference standards GB5675 GB6414 HG/T2434 HG-2432 HG/T2105 HG/T2143bzxz.net Gray cast iron classification Casting size tolerance Glass plate and glass tube for liquid level gauge Technical conditions for sugar glass valves Technical conditions for sugar glass equipment According to glass equipment, slip-on flange Inserted glass equipment pipe outlet Raised plate type flat welded pipe flange 3 Types, basic parameters and main dimensions 3.1 The structural types are divided into D type (non-insulated type) and W type (insulated type). 3.2 Basic parameters and main dimensions are as per the requirements of Figure 1, Table 1 and Table 2. 3.3 The flange sealing surface of the liquid level gauge is flat, the nominal pressure of the flange is PNO.6MPa, the nominal diameters are DN50 and DN65, and the connection dimensions are as per the relevant provisions of HGJ45 or HG/T2105 and HG/T2143. 3.4 Marking Marking example: Non-insulated sugar glass liquid level gauge, flange nominal diameter DN50, nominal length L: 800mm Marking: liquid level gauge D50-800, HG/T2433-93 Insulated pond glass liquid level gauge, flange nominal diameter DN65, nominal length 200 0mm mark: liquid level gauge W65-2000, HG/T2433-93. Approved by the Ministry of Chemical Industry of the People's Republic of China on 1993-06-14 and implemented on 1994-01-01 HG/T2433--93 Upper steam inlet Lower water outlet Note: steam inlet and outlet pipe A with insulation structure for protective cover Note: DN50B-115d-110 DN65B-135d=130 Nominal length Technical requirements Standard number Light-proof length||t t||HG/T-2433-93 Details Lower ring Gland nut Glass tube @19x3 Protective cover Insulation tube Positive spherical tube Table 2 Size table, Connecting flange Glass transfer iron Polytetrazodone Flexible graphite ring Tetrazodone Q235-A Borosilicate glass Glass casting Q235-A Red copper T3 Assembly Input weight plate g (equivalent to HT200) Eshi egg asbestos packing or polyperfluoroethylene propylene chrome plating on the outer surface (equivalent to HT200) Connecting flange The valve material and manufacturing technical conditions of the sugar glass liquid level gauge shall comply with the relevant provisions of HG2432 and HG/T2434. 4.1 The classification, size and deviation requirements of castings shall comply with the provisions of GB5675 and GB6414. 42 The water pressure test pressure P of the liquid level gauge is 0.9MPa. 4.3. Glass tube for sugar glass liquid level gauge. Specifications, dimensions and tolerances are shown in Figure 2, Table 3 and Table 4. Others are in accordance with the relevant provisions of QB776, Surface gauge nominal length Surface grinding Glass tube length HG/T2433-93 Reference weight plate Liquid level gauge nominal length Allowable tolerance End surface grinding Glass tube length| |tt||The straightness tolerance of the glass tube is less than or equal to 0.2% of the tube length. The roundness of the corrugated glass tube is less than or equal to 0.5mm. The verticality tolerance of the wall and outer surface of the glass tube is less than or equal to 1mm. The nominal length of the liquid level gauge is greater than 1500mm. A fixed lug is added in the middle of the protective cover.4.5 Packaging, transportation and storage 5.1 The exposed sugar glass surface is sealed with a flange cover and a soft gasket. Collisions must be avoided during handling and transportation. 5.3 The product should be accompanied by a packing list, product certificate and product instructions.5.4 The product should be stored indoors and is not allowed to be stacked in the open air.
