Abstract
The utility model relates to a valve which can output a flow signal, belonging to the technical field of the valve. The valve is used for solving the problems of fluid charging and pipeline simplifying. The technical scheme of the valve is as follows: the valve comprises a valve body, a valve core, a valve rod and a handle; after improvement, a flow sensor is additionally arranged and is composed of an LED (light emitting diode), photoelectric tubes and a shield; the LED is fixed at the top part of the valve rod, the illuminating direction of the LED is vertical to the valve rod, the shield is fixed at the top part of the valve body, the photoelectric tubes are fixed on the inner wall of the shield and are uniformly distributed on a rotary-illuminating track with equal diameter of the LED, and the combined level output by all the photoelectric tubes is just an output signal of the flow sensor. The valve not only has the function of controlling a pipeline, but also can output an electric signal which reflects the valve opening; by utilizing the valve, the structure of the pipeline is simplified, the material consumption is reduced and the installation cost is decreased.
Description
Technical field
The utility model relates to a kind of improved valve, can export the electrical signal of reflection valve opening size, belongs to valve technology field.
Background technique
In water supply, air feed (vapour) pipeline, need to use a large amount of valve fluid flow to control.When the needs convection cell measures (as bathhouse water, rock gas etc.), then need in pipeline, to install measuring apparatus.Comparatively advanced at present apparatus for metering fluids is generally electronic type, comprises measuring instrument and is installed on ducted flow transducer.The installation of flow transducer will inevitably increase ducted pipe fitting quantity, makes pipeline configuration complicated, improves materials consumption and installation cost, and this is that people are reluctant to see.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of valve that has the exportable flux signal of flow transducer function concurrently is provided.
The alleged problem of the utility model realizes with following technical proposals:
A kind of valve of exportable flux signal, comprise valve body, spool, valve rod and handle in the formation, after the improvement, set up flow transducer, described flow transducer is made of light emitting diode, phototube and protective housing, described light emitting diode is fixed in the valve rod top, its irradiation directions is vertical with valve rod, described protective housing is fixed on the valve body top, each phototube is fixed on the inwall of protective housing, and be distributed on the isometrical track of light emitting diode rotary irradiation, the combination level of all phototube outputs is the output signal of flow transducer.
The valve of above-mentioned exportable flux signal is set up annular flashing between described light emitting diode and valve body, described flashing is set on the valve rod, and the internal diameter of its outer rim and protective housing is complementary.
The valve of above-mentioned exportable flux signal, the quantity of described phototube are 8～16.
The valve of above-mentioned exportable flux signal, the isometrical track of described light emitting diode rotary irradiation is a quarter turn.
A plurality of phototube collections that the utility model utilization is installed on the protective housing inwall are installed on the valve rod top, the optical signal that light emitting diode sent that rotates with valve rod and spool, as the valve opening signal, the electronics message accounting utilizes this signal and just can calculate the flow of unit time inner fluid and the expense of dealing with in conjunction with the valve port bore.The utility model not only has pipeline control function, can also export the electrical signal of reflection valve opening, has used this valve just can save flow transducer in the fluid supply tube road, has both simplified pipeline configuration, has reduced materials consumption and installation cost again.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view.
Each label is among the figure: 1, valve body; 2, spool; 3, handle; 4, protective housing; 5, phototube; 6, light emitting diode; 7, valve rod; 8, locating stud; 9, flashing; 10, valve rod pillar.
Embodiment
Referring to Fig. 1, what provide among the figure is a ball valve, also can be the valve of other types when specifically implementing.There is outside thread at valve body 1 two ends of ball valve among Fig. 1, are used for being connected with fluid transmission pipe.A spherical valve core 2 is installed in the valve body 1, and spherical valve core 2 is installed on the valve body 1 by the back shaft of below and the valve rod 7 of top, and the cross section on valve rod 7 tops is square, and the cross section of bottom is circular; Valve rod 7 circular cross-sections and jointing place, square-section are installed with handle 3, pull handle 3 and can make valve rod 7 be with spool 2 to rotate around back shaft, and slewing area is a quarter turn, and two limit positions are corresponding to the maximum position of valve closing position and valve opening.The main body of 2 on-off actions of spherical valve core is the steel ball that there is a through hole at a middle part, the difference of pulling the angle that spool 2 turns over along with handle 3 makes the area difference of steel ball through hole over against pipeline, thereby flowing through the Fluid Volume of pipeline in the control unit time, is the state of valve complete closed shown in Fig. 1.In order to be connected with protective housing 4, the top of valve body 1 is provided with the valve rod pillar 10 that a cross section is about 3/4 circumference, this is because the slewing area of handle 3 is a quarter turn, valve rod pillar 10 is milled about quarter turn and stays about 3/4 circumference and can make handle 3 not interrupted in pulling process.There is outside thread the top of valve rod pillar 10, is used for being connected cooperation with the internal thread of protective housing 4.On the quarter turn of protective housing 4 inwalls phototube 5 is housed.A light emitting diode 6 is installed on the end face of valve rod 7, when being distributed in light emitting diode 6 with valve rod 7 rotations, phototube 5 is radiated on the track of protective housing internal face, pull in valve rod 7 rotating process at handle 3, the laser beam that light emitting diode 6 sends is radiated on the different phototube 5, makes irradiated phototube 5 induce high level.As long as the output level of each phototube 5 is encoded, be transported to electronic charge account equipment such as single-chip microcomputer then and can collect different expenses to the fluid that flows through pipeline in the unit time according to the difference of valve opening size.The insulativity of overflowing phototube 5 and light emitting diode 6 from the matching gap of the valve rod 7 of spherical valve core 2 and valve body 1 for the fluid that prevents in the valve body 1 impacts, an annular flashing 9 is installed above valve rod pillar 10, the bottom surface of flashing contacts with the end face of valve rod pillar 10, has 8 pairs of flashings of a locating stud to carry out axial restraint above flashing.
Electronic charge account equipments such as being connected to single-chip microcomputer after phototube 5 level codings can be realized easily the classification of fluid charges, can be used for need such as drinking machine, bathhouse, fuel gas transportation pipeline carry out the classification charging to various fluid flows occasion.
