Abstract
The utility model relates to a connecting device for pressure gauge base, in which flanges are connected with the two ends of the connecting device for pressure gauge base and a hole plate with a piece of glass in the inner wall of a hole by bolts and nuts, a pressure gauge base is fixed on the hole plate by bolts and gaskets, a protective cover is arranged between a step end surface and a pad (8) which are arranged on the lower part of the connecting device for pressure gauge base, a diaphragm is arranged between the pad (8) and the hole plate, threaded holes are arranged on the upper part of a connecting pipe, in which a pressure gauge can be installed, the side surface of the connecting pipe is provided with a threaded hole, in which a threaded clog can be screwed on, heat radiating fins are arranged in the middle of the connecting pipe, the hole plate with a piece of glass is resistant to acid and alkali erosion, having long service life.
Description
The utility model relates to a kind of pressure gauge stand coupling arrangement, belongs to the technical field of chemical plant annex.
Aspect equipment such as chemical plant autoclave, want frequent Monitoring and Controlling still internal pressure situation in the course of the work, owing to often contacting with soda acid in the still, pressure gauge stand bottom surface corroded, life-span is short, must shutdown maintenance more renew part, both time-consuming, influence is produced again, therefore must improved aspect the tensimeter holder structure.
The purpose of this utility model is that a kind of pressure gauge stand coupling arrangement will be provided, it can overcome above-mentioned shortcoming, warded off glassy layer at orifice plate two end surfaces and the hole inwall that contact with medium in the still, existing enough intensity can resist soda acid again and corrode, make the life-span long, can correctly reflect pressure condition, needn't often keep in repair and renew.
The purpose of this utility model is to realize like this; flange is connected with orifice plate with bolt, nut collar; the pressure gauge stand is fixed by bolts to above the orifice plate; take over top screw hole is arranged; tensimeter is housed; there is threaded hole the side; the hexagonal of can packing into screw thread stops up; it is thinner to take over the middle part external diameter; heat radiator is housed; taking between lower step end face and the pad has garden arc protective cover, and barrier film is contained between pad and the orifice plate, and orifice surface and endoporus hole wall are all warded off the erosion that glassy layer can resist soda acid with special technology.
Fig. 1 is a pressure gauge stand coupling arrangement synoptic diagram
Now in conjunction with the accompanying drawings the structure of pressure gauge stand coupling arrangement is described in detail:
By Fig. 1; lap joint flange (1); with bolt (12); nut (3); packing ring (4) is connected with the orifice plate (6) that two end surfaces and hole wall are all warded off; mouth of pipe pad (5) is housed below the orifice plate (6); pressure gauge stand (11) bolt (10); packing ring (9) is fixed on above the orifice plate (6); pressure gauge stand (11) top is a tubulose Cylinder; the middle part is a cone; the bottom is a ring-shaped step; the protective cover (18) of garden arc is housed between step end face and the pad (8); barrier film (19) is contained between pad (8) and orifice plate (6) end face; barrier film (19) is gone up also has pad (7); take over (13) top threaded hole (21) is arranged; the thread head of tensimeter (15) and pad (14) together are screwedly mounted in this hole (21); the external diameter of taking over (13) middle part is thinner; the heat radiator that Special Casting Iron is made (20) just is sleeved on above the adapter (13); taking over (13) upper side has threaded hole (22), and the hexagonal screw thread stops up (17) and is contained in this threaded hole with pad (16).
In the chemical plant autoclave; the situation of change of pressure is wanted timely observing and controlling system in chemical reaction process; use the structure of this pressure gauge stand; because medium can corrosion surface not be warded off the orifice plate of glass, the orifice plate life-span is long, needn't often change; reduce the shutdown maintenance loss; the glassy layer in glass lined hole, but there are enough intensity acid and alkali-resistances to corrode, also can stand general high temperature.
Compared with prior art, this connecting device for pressure gauge base has following advantages:
1. the orifice plate that contacts with the chemical industry equipment reactor mouth of pipe, surface and endoporus have all been warded off glassy layer with special process, can resist the erosion of soda acid in the still, and the life-span is long.
2. the glass-lined coating combination is firm, incrust.
3. simple in structure, cost is low, can save alloy steel products.
