Description
Technical field
The utility model relates to a kind of instrument and meter of measuring pipeline fluid flow, specifically a kind of there is high-pressure-resistant sealed form can installation inserted electromagnet flow meter with pressure.
Background technology
Common pipe electromagnetic flowmeter because in the time of installation, maintenance, must stop, pressure release could install; Do not allow to need with plug-in type magnetic field flowmeter must measuring again of cutout, broken pipe in some operating mode, although can continue to flow and common inserted electromagnet flow meter has, but its seal form is not high pressure resistant, often cause leakage, so inserting-type flowmeter uses not general now.
Utility model content
The utility model is in order to address the above problem, provide a kind of simple in structure there is high-pressure-resistant sealed form can installation inserted electromagnet flow meter with pressure, this inserted electromagnet flow meter band ball valve and be designed with high pressure seal, guarantee that this flowmeter does not need stopping production, cutout, emptying, disconnected pipe in any high pressure situation, can realize online perforate, installation, dismounting, can reduce a large amount of engineering constructions, reduce construction costs.
The purpose of this utility model is to adopt following technical proposals to realize:
What have a high-pressure-resistant sealed form can an installation inserted electromagnet flow meter with pressure, comprises probe, insertion rod, high-pressure-resistant sealed device, ball valve, terminal box; Electrode and field coil are equipped with in described probe inside, measure required signal; Described insertion rod connects respectively probe and terminal box; The lead-in wire of electrode and field coil arrives terminal box by insertion rod, is connected with the electromagnetic transducer in terminal box; Described ball valve and high-pressure-resistant sealed device are fixed in insertion rod; Described high-pressure-resistant sealed device, comprises can, an O type sealing rubber ring, the 2nd O type sealing rubber ring, back-up ring, hold-down ring, fastening cap; There is the seal groove of two indents can inside, and an O type sealing rubber ring is placed in seal groove, and can bottom is connected with ball valve; Back-up ring is fixed in insertion rod; Can top is fixed by back-up ring and fastening cap, and inside seals up by the 2nd O type sealing rubber ring and hold-down ring; The size of a described O type sealing rubber ring is greater than the size of the 2nd O type sealing rubber ring.
Described high-pressure-resistant sealed device, can be made up of can, 2 large O type sealing rubber rings, 2 little O type sealing rubber rings, back-up ring, hold-down ring, fastening caps.Because its guide ring is welded in insertion rod, while measuring high-pressure fluid for a long time, it is loosening that it can make whole packoff be difficult for; Its sealing effectiveness of sealing system of 4 O-ring seals and hold-down ring composition is more a lot of than common good sealing effect.This high-pressure-resistant sealed device makes inserted electromagnet flow meter can reach fabulous sealing effectiveness, can withstand again high-pressure fluid and impact for a long time, has extended the serviceable life of inserted electromagnet flow meter.Described high-pressure-resistant sealed device not only has high-pressure-resistant sealed effect, also can realize installation with pressure together with ball valve.
Described ball valve and high pressure seal acting in conjunction, make inserted electromagnet flow meter have the function of installation with pressure, can realize continuous pipe, cutout, just installation, maintenance online, dismounting flowmeter.
The beneficial effects of the utility model are, solved common pipe electromagnetic flowmeter because in the time of installation, maintenance, must stop, problem that pressure release could be installed and the common not high pressure resistant problem that often causes leakage of its seal form of inserted electromagnet flow meter, not only reduce construction costs, can also guarantee the permanent normal work of inserting-type flowmeter, and have simple in structure, improved the advantages such as measuring accuracy.
