Abstract
The utility model discloses a high-pressure flow meter. The utility model comprises an enclosure having an inner passage, an interlayer and a scale; a permeable pivoted float arranged in the interlayer; and a core rod arranged in the inner passage. The utility model is characterized in that mounting boards having a liquid inlet and a liquid outlet are provided on both ends of the enclosure; the liquid inlet and the liquid outlet are communicated with the inner passage; a plurality of mounting holes are provided on each of the mounting boards; a toroidal magnetic core is enclosed on the core rod; the toroidal magnetic core is arranged in the way that a gap is reserved between the toroidal magnetic core and the inner side of the enclosure. The utility model is applicable on valve blocks of low discharge, has the advantages of high sensitivity, convenient installation and high pressure resistance.
Description
Technical field
The utility model relates to a kind of high-pressure flowmeter that is used to measure low discharge.
Background technology
Present widely used high-pressure flowmeter comprises and has inlet, liquid outlet, the housing of interlayer and scale, be positioned over the magnetic conductivity pivoted float in the interlayer, be arranged at the plug in the enclosure interior passage, on plug, be set with the magnet ring of band through hole, be arranged on the spring between magnet ring and the housing inside top, this high-pressure flowmeter mainly is applicable on the valve piece of big flow, because if flow is less, the displacement of magnet ring its rising under the effect of spring is less, also less by the displacement that the magnetic conductivity pivoted float of its drive rises, cause the sensitivity of this high-pressure flowmeter relatively poor, be difficult to accurately measure the flow of this moment; High-pressure flowmeter connects by screw thread and the valve piece that is arranged on inlet and liquid outlet place simultaneously, is not easy to install.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, the high-pressure flowmeter of provide on a kind of valve piece that can be applicable to low discharge, sensitivity is higher, being convenient to install.
For achieving the above object, high-pressure flowmeter of the present utility model, comprise the housing that has inner passage, interlayer and scale, be positioned over magnetic conductivity pivoted float in the interlayer, be arranged at the plug in the inner passage, it is characterized in that being respectively equipped with the installing plate of band inlet, liquid outlet at the housing two ends, inlet, liquid outlet are communicated with the inner passage, also be provided with several mounting holes on the every installing plate, be set with the magnet ring of band through hole on plug, this magnet ring and housing inboard are the gap and are provided with; When fluid enters flowmeter from inlet, when flowing through magnet ring, because the fluid that flows, produce pressure reduction when flowing through the inner chamber of magnet ring, promote magnet ring and move upward, driving the magnetic conductivity pivoted float simultaneously moves upward, demonstrate the size of flow, owing to do not have the suppression of spring, even this moment, flow was less, the displacement that magnet ring rises is also bigger, can significantly improve flowmeter sensitivity; The installing plate at housing two ends is convenient to install in the enterprising andante formula of the oil system valve piece of high pressure;
As further improvement of the utility model, in described inlet, be provided with magnet ring, when fluid process inlet, can remove the irony impurity in the fluid, when guaranteeing magnet ring work, do not influence precision because of sucting irony impurity, further improve sensitivity;
As further improvement of the utility model, described housing is a stainless steel, can improve the ability of the anti-high pressure of flowmeter;
In sum, the utility model is applicable on the valve piece of low discharge, have highly sensitive, be convenient to install, the advantage of anti-high pressure.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
Embodiment
By illustrated in figures 1 and 2, the high-pressure flowmeter of the utility model embodiment, comprise the Stainless Steel Shell 5 that has inner passage, interlayer 3 and scale, be positioned over magnetic conductivity pivoted float 6 in the interlayer 3, be arranged at the plug 9 in the inner passage, it is characterized in that being respectively equipped with the installing plate 10 of band inlet 1, liquid outlet 2 at housing 5 two ends, inlet 1, liquid outlet 2 are communicated with the inner passage, in inlet 1, be provided with magnet ring 7, also be provided with four mounting holes on the every installing plate 10, be convenient to install in the enterprising andante formula of the oil system valve piece of high pressure; Be set with the magnet ring 8 of band through hole on plug 9, this magnet ring 8 is the gap with housing 5 inboards and is provided with; When fluid enters flowmeter from inlet 1, irony impurity in the magnet ring 7 adsorbable fluid, when fluid flows through magnet ring 8, produce pressure reduction, promote magnet ring 8 and move upward, driving magnetic conductivity pivoted float 6 simultaneously moves upward, demonstrate the size of flow, owing to do not have the suppression of spring, even this moment, flow was less, the displacement that magnet ring 8 rises is also bigger, can significantly improve flowmeter sensitivity.
Claims (3)
