Abstract
The utility model relates to a combined micro-regulation liquid flow switch which comprises a valve body 1 a press cap 3 of the valve body and a valve core. The utility model is characterized in that the valve core is composed of a main valve core 2 and a micro-regulation quantitative valve core 6. The valve body 1 and the main valve core 2 are respectively provided with a position limiting groove 7 and a position limiting key 8 which are matched mutually and used for closing and opening the main valve core 2. The micro-regulation quantitative valve core 6 is arranged in the main valve core 2, and the head part of the micro-regulation quantitative valve core 6 is designed into a circular sphere. The utility model has the characteristics of simple structure, easy fabrication, low cost, convenient operation, accurate flow control, little local loss, etc.
Description
Technical field: the utility model relates to a kind of fluid flow switch gear, particularly a kind of combined type fine setting fluid flow switch.
Background technique: at present, the fluid flow switch is of a great variety.Usually in liquid is carried, be the unit time control flow rate, at the fluid pressure weighing apparatus regularly, the general degree that adopts switch open, come the flow of controlling liquid, especially on some spray liquid facility, the flow of liquid needs often to adjust, and need often close, open according to mode, the method switch of operation.So, switch of every unlatching must be readjusted fluid flow one time.In order to make the fluid flow precise control, some sprays the switch of facility and done tangible scale mark on angle of swing, guarantees the accurate flow of liquid.So, can only interior several flows of guarantor unit's time.But can not any required flow in guarantor unit's time.Simultaneously, the sectional area control flow rate with switch dwindles pipeline certainly will cause local losses such as vortex, collision and velocity variations, thereby influence using effect.The purpose of this utility model is: at the problem that above-mentioned prior art exists, design provides a kind of simple in structure, opens free; Fluid flow is controlled on demand, and is convenient, accurate; It is minimum that its three kinds of local losses reduce to, the combined type fine setting fluid flow switch of making easily.
Summary of the invention: the utility model is realized by following manner: a kind of combined type fine setting fluid flow switch, comprise valve body 1, valve body pressure cap 3 and spool, the top of main valve plug 2 is provided with switch knob 4 and passes through handle pressing cap 5 with main valve plug 2, on the valve body 1 that switch knob 4 is installed in, it is characterized in that: said spool is by main valve plug 2, finely tuning quantitative spool 6 forms, be respectively equipped with the restraining groove 7 and the positive stop key 8 that cooperatively interact on valve body 1 and the main valve plug 2 and be used to control closing or opening of main valve plug 2, restraining groove 7 that is provided with respectively on common valve body 1 and the main valve plug 2 and positive stop key 8 can be controlled the main valve plug 2 a certain angles of rotation (as being set to 90 °) and close or open, finely tuning quantitative spool 6 is arranged in the main valve plug 2, as shown in Figure 1.
The head design of the quantitative spool 6 of said fine setting is a spherosome, and as shown in Figure 1, this design mainly is to consider the local losses such as variation of vortex, collision and the speed of liquid and 6 generations of the quantitative spool of fine setting are reduced to minimum.
Working principle of the present utility model is: (1), rotary switch handle 4, and main valve plug 2 rotates 90 ° (spacing by restraining groove is arranged) and opens; (2), when producing the needs control flow rate, the quantitative spool 6 of rotary fine adjustment is regulated flow, thereby reaches production requirement; (3), in process of production, back and forth close or open switch, guarantee flow constant (prerequisite is that the pressure of fluid is constant), because the head of the quantitative spool 6 of fine setting is spheroids, institute is so that local losses such as vortex, collision and velocity variations reduce to minimum.From above-mentioned working principle, be not difficult to find out that key problem in technology of the present utility model is that main valve plug 2 is main quantitative switching spool, it simultaneously is again the valve body of quantitative spool 6 switches of fine setting, so, main switch main valve plug 2 is when opening or closing, it is constant to finely tune the relative main valve plug in quantitative spool 6 its positions, therefore guarantees that flow is guaranteed constant under the identical situation of hydrodynamic pressure.This combined type fine setting fluid flow switch is mainly used in manually, power distributor tool etc.This use is novel to be compared with prior art, have simple in structure, easily manufacturing, characteristics such as cost is low, and is easy to use, and flow control is accurate, local losses is less.
Description of drawings:
Fig. 1 is the general structure schematic representation of model utility.
Among the figure: 1 valve body, 2 main valve plugs, 3 valve body pressure caps, 4 switch knobs, 5 handle pressing cap, the quantitative spool of 6 fine settings, 7 restraining grooves, 8 positive stop keys.
Embodiment: a kind of combined type fine setting fluid flow switch, comprise valve body 1, valve body pressure cap 3 and spool, the top of main valve plug 2 is provided with switch knob 4 and passes through handle pressing cap 5 with main valve plug 2, on the valve body 1 that switch knob 4 is installed in, it is characterized in that: said spool is by main valve plug 2, finely tuning quantitative spool 6 forms, be respectively equipped with the restraining groove 7 and the positive stop key 8 that cooperatively interact on valve body 1 and the main valve plug 2 and be used to control closing or opening of main valve plug 2, restraining groove 7 that is provided with respectively on common valve body 1 and the main valve plug 2 and positive stop key 8 can be controlled the main valve plug 2 a certain angles of rotation (as being set to 90 °) and close or open, finely tuning quantitative spool 6 is arranged in the main valve plug 2, as shown in Figure 1.
The head design of the quantitative spool 6 of said fine setting is a spherosome, and as shown in Figure 1, this design mainly is to consider the local losses such as variation of vortex, collision and the speed of liquid and 6 generations of the quantitative spool of fine setting are reduced to minimum.
