Abstract
The utility model discloses a device for detecting flow, which comprises a float flowmeter and a proximity switch. The float flowmeter is internally provided with a float. The proximity switch is fixedly provided at one end of a clamping plate, and the other end of the clamping plate is movably equipped on the float flowmeter. An end of the proximity switch faces the central part of the float flowmeter. One end of the float flowmeter is connected with a joint. The device for detecting flow compensates an insufficiency that the person can only measure the number of the flow through ocular estimation in a majority of float flowmeter through detecting position of the float in the float flowmeter by the proximity switch and outputting an electrical signal. The device for detecting flow has the following advantages: simple structure, low production cost, high convenience in operation, and high efficiency.
Description
Technical field
The utility model relates to gauging instrument, is specifically related to a kind of device that detects flow.
Background technology
The existing glass spinner-type flowmeter; It is made up of transparent Taper Pipe, float, upper flange, last seal, lower seal, web joint; Transparent Taper Pipe, upper flange, lower flange, last seal, web joint are connected by bolt; Be carved with reading on the transparent Taper Pipe, transparent Taper Pipe endoporus enlarges from bottom to top, and float is positioned at transparent Taper Pipe and moves up and down with the fluid flow size.When fluid is gone into from the lower flange orifice flow with certain flow, when the upper flange orifice flow went out, float can be stabilized in the transparent Taper Pipe on certain position, is carved with reading on the transparent Taper Pipe, according to the readable value that effluents of the reading of float position.Glass rotameter is simple in structure, reliable, but does not have electric signal output, can not directly be used as the detecting element of fluid flow automatic control system and fluid flow Long-Range Surveillance Unit.
The utility model content
The purpose of the utility model is in order to remedy the deficiency of prior art, a kind of device that detects flow to be provided, through position near float in the switch detection suspended body flowmeter, and the output electric signal, remedy the deficiency that most suspended body flowmeters can only be estimated flow value.
The technical scheme of the utility model is following:
A kind of device that detects flow; Include suspended body flowmeter and near switch; In the described suspended body flowmeter float is arranged, it is characterized in that: describedly be fixedly mounted on an end of clamping plate near switch, the other end of said clamping plate is movably arranged on the suspended body flowmeter; Said end near switch is towards the middle part of suspended body flowmeter, an end jointing of described suspended body flowmeter.
The device of described detection flow is characterized in that: the material of said float is a metal material.
The device of described detection flow is characterized in that: describedly be fixedly mounted on an end of clamping plate near switch through clip and housing screw, the other end of said clamping plate is movably arranged on the suspended body flowmeter through the scalable housing screw.
The beneficial effect of the utility model:
The utility model is through detecting the position of float in the suspended body flowmeter near switch, and the output electric signal, has remedied the weak point that most suspended body flowmeters can only be estimated flow value, it is simple in structure, production cost is low, easy to operate, efficient is high.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of the utility model structure.
Embodiment
Referring to Fig. 1,2; A kind of device that detects flow includes suspended body flowmeter 1 and near switch 2, the float 8 of metal material is arranged in the suspended body flowmeter 1; Be fixedly mounted on an end of clamping plate 5 through clip 3 and housing screw 4 near switch 2; The other end of clamping plate 5 is movably arranged on the suspended body flowmeter 1 through scalable housing screw 7, near the end of switch 2 towards the middle part of suspended body flowmeter 1, an end jointing 6 of suspended body flowmeter 1.
During work, detected fluid flows in suspended body flowmeter 1.When float 8 formed annular space in detected fluid and the suspended body flowmeter 1, float 8 upper and lower sides produced the power that differential pressure forms float 8.When float 8 suffered raising forces when being immersed in the detected fluid float 8 weight; Float 8 just rises, and the annular space area increases thereupon, and annular space place rate of flow of fluid descends immediately; The differential pressure of float 8 upper and lower sides reduces; Act on float 8 raising forces and also reduce thereupon, up on when equaling to be immersed in the fluid float 8 weight, float 8 just is stabilized in a certain height.When float 8 near switch 2 detection positions the time, show that flow is in the value of setting.
Claims (3)
1. device that detects flow; Include suspended body flowmeter and near switch; In the described suspended body flowmeter float is arranged, it is characterized in that: describedly be fixedly mounted on an end of clamping plate near switch, the other end of said clamping plate is movably arranged on the suspended body flowmeter; Said end near switch is towards the middle part of suspended body flowmeter, an end jointing of described suspended body flowmeter.
2. the device of detection flow according to claim 1 is characterized in that: the material of said float is a metal material.
