Abstract
The utility model belongs to the technical field of the measurement for liquid, characterized in that the utility model comprises a gear type liquid flowmeter, a straight insertion type valve, and a control mechanism composed of a cam, a shifting piece, a rotary shaft, a bending rod, a straight rod, a fixing support, and a spring for controlling the value. The utility model is mainly used for the quantitative control for liquid which flows in and out from the same pipe. The utility model has the characteristics of simple structure, low production cost, and wide application range.
Description
The utility model belongs to the liquid meter technical field.Specifically, it relates to the control device of a kind of liquid from the measuring fixed amount of same pipeline inflow and outflow.
At present, utilize the control device of same pipeline quantitative filling or output liquid in the fixed container, kind is a lot.But great majority are the control device that adopt electromechanical integration, the control principle of these devices is that a sensor is installed in the container of holding liquid, when the liquid in pouring into container reaches a certain amount of, sensor transmits a control signal on the switch of by-pass valve control on the fluid pipeline or pumping source, to realize the quantitatively purpose of control.These utilize the liquid quantitative control device of the electric mechanical integrated type of sensor, complex structure, and also cost is higher, generally only limits to the quantitative control of large scale industry pipeline liquid inflow and outflow.
The purpose of this utility model is installed on liquid quantitative control device on the shared same pipeline of inflow and outflow with regard to providing a kind of mechanical type simple in structure, that cost is low.
The purpose of this utility model is achieved in that reciprocating type liquid quantitative control device, comprise a fluid flowmeter, a direct insertion valve, on the gear shaft of described flow meter, fix a cam, a rotating shaft is fixed between the gear pedestal, plectrum of vertical fixing in described rotating shaft, and with the tangent subsides of cam, described rotating shaft lower end vertical direction connects a knee, the same straight-bar in the top of knee connects, and straight-bar passes the fixed mount that is fixed on the inner-walls of duct, is used to control the spool of described straight-bar type valve, the valve side has a projection on described straight-bar, spring of cover on the straight-bar between this projection and fixed mount.
Its additional technical feature is:
Pulling out sheet is cut on the same plane with described cam.
Pulling out has an angle α between sheet and described knee,
45 °＜α of angle≤90 °
The spool of direct insertion valve is the step spool.
Fix a horn ring on the gear shaft, described cam is enclosed within on this horn ring.
Horn ring can be three horn rings, four horn rings or five horn rings.
The utility model proposed is installed in mechanical type liquid quantitative control device on the pipeline, compares with the control device of electromechanical integration of the prior art, has advantage simple in structure, that cost is low, the scope of application is wide.
The drawing explanation:
Fig. 1: reciprocating type liquid quantitative control device structure chart;
Fig. 2: the use principle figure of reciprocating type liquid quantitative control device;
Below in conjunction with accompanying drawing this practicality new concrete structure and operating principle are described in further details:
Be illustrated in figure 1 as the structure chart of a quantitative control device in the reciprocating type liquid inlet container.It comprises 1, one direct insertion angle of gear type liquid meter type valve 20 and by the straight-bar 9 of band projection 8, knee 5, rotating shaft 15, cam 4, plectrum 14, and the controlling organization of the valve 20 formed of spring 7, fixed mount 6.Its concrete structural relation is: pass on the gear shaft 16 of flowmeter 1, being fixed with a triangle (also can be four jiaos, five angie types, hexagonal etc., set its angle number according to concrete needs) wheel 2 cam 4 of cover on this three horn ring, pass 19 of the fixed mounts of flow meter and fix a rotating rotating shaft 15, and fix one in its vertical direction and pull out sheet 14, this plectrum is with one same plane, cam 4 places and proper on the periphery of cam.A knee 5 is also fixed with this vertical direction in the lower end of rotating shaft 15, and with forming an angle α between the plectrum 14, this angle α is chosen between 45 °-90 °, but preferably vertical mutually, i.e. α=90 °.Top at knee 5 is connected with straight-bar 9 along pipeline 11 directions, and this straight-bar passes the Push And Release that the fixed mount 6 that is fixed on the inner-walls of duct is used for controlling the step spool 12 of straight-bar type valve 20.In order to realize control, the valve side has a projection 8 on straight-bar 9, overlaps a spring 7 on the straight-bar of 6 of this projection 8 and fixed mounts.
Use principle: when liquid when pipeline flows into container by this device, (as shown in Figure 2), at first open valve 20, promptly mention valve rod 13 be inserted on the step of spool 12 because the effect of spring 7 promotes straight-bar 9, and valve be in closed condition.And the sheet 14 that pulls out in the rotating shaft 15 this moment is cut on the inclined to one side plane surface that is affixed on cam 4, when liquid flows through flow meter 1, impeller 18 rotates, and drive three horn rings 2 and the cam 4 that are placed in it by gear 3 and rotate, when cam 4 goes to plectrum 14 when cutting the salient point that is affixed on cam, the displacement of promptly pulling out sheet 14 drives rotating shaft 15 and is attached thereto the knee 5 that connects also rotates, and straight-bar 9 is retracted.And the valve 20 that is in closed condition closes spool under the effect of its valve rod spring 10, and then liquid stops to flow into.The quantity that is fixed in this moment on the indicated dial plate of the pointer 17 on gear shaft 16 tops then is the amount of the liquid in the inflow container of setting.Open valve 20 when same pipeline flows out liquid in the container, liquid flows out along pipeline and through this device.Impeller 3 revolution, and driven gear axle 16 and be enclosed within cam 4 reversings on this are flowed out fully until liquid, therebetween valve-off 20 at any time.
When changing the capacity of liquid in containers as required, and the amount that is changed is in the same order of magnitude scope with the original amount of setting, and only needs to change cam 4 and the relative position of three horn rings 2 that are nested gets final product.(three horn rings can be four horn rings, five horn rings or more polygonal wheel, and its angle number is many more, and then the flow of being controlled quantitatively can be accurate more).
When the capacity of change liquid in containers, then is inserted in cam 4 on other rotary gear shaft and can realizes during not at an order of magnitude with the original capacity of setting.
This mechanical type liquid quantitative control device has characteristic of simple structure, and it both can be used for large-scale industrial pipeline, and the quantitative flow-control of liquid is as various oil depots, oil tank, water pot etc.Also can be used in the quantitative retaining control of family such as solar storage water tank.
