Description
The utility model belongs to valve type, and what be specifically related to is a kind of constant flow regulator of switch valve.
At present, because the pressure in the pipeline network system and the continuous variation effect of each parts of pipeline resistance in running cause the mass flow discrepancy of flow of liquid in the piping network to weigh, influenced the riding quality of flow of liquid in the piping network.
The purpose of this utility model is exactly in order to solve the mass flow discrepancy weighing apparatus problem of flow of liquid in the existing piping network, to have designed a kind of constant flow regulator of switch valve
The utility model is that following mode realizes: a kind of constant flow regulator of switch valve, be installed on the liquid flowing channel of switch valve body, the switch valve body includes the import 1 of flow of liquid, outlet 2, the moving flap 4 that it is characterized in that constituting the constant flow regulator of switch valve has a hollow shaft that piston shaft 12 axially is installed, the outer, bottom of hollow shaft is provided with valve block 3, the upper end of hollow shaft and piston cylinder 5 connect, the bottom of said piston shaft 12 is provided with guide pad 10, piston shaft 12 pocketed springs 6 are to guide pad 10, the piston 11 that penetrates hollow shaft and connect in the piston cylinder by screw 15, the lower end of piston shaft 12 is connected with balance flap 16, the upper cylinder cover 13 of the piston cylinder 5 of said installation piston 11 is installed on the piston cylinder mouth by the threaded piece form, upper cylinder cover 13 top axle are provided with joint 14 in the heart, and joint 14 connects can be opened or the adjustment disk that has scale 17 of throttle down passage.The adjustment disk 17 that has scale is provided with interior six sides, when adjusting valve channel, rotates the purpose that adjustment disk can reach open and close or regulating valve channel sized with hexagon.Valve block 3 on the said moving flap 4 and the fixed valve plate of valve channel 7 constitute the switch of switch valves.Said piston shaft 12 can be made one with balance flap 16.
The utility model is installed in the switch valve body, rotates adjustment disk 17, opens the switch of the switch valve that the fixed valve plate 7 of valve block 3 and valve channel on the moving flap 4 constitutes, and connects liquid flowing channel in the piping network.The concrete working procedure of the constant flow regulator of switch valve is as follows: the flow pressure of establishing the flow of liquid in the piping network is P at the pressure of import 1
1, the pressure that enters the fluid flow of inner chamber by the passage that cooperates with the upper edge 8 and the lower edge 9 of balance flap 16 is P
2, on the valve block 3 of moving flap 4 and the outlet that fixing valve block 7 cooperates to the flow pressure that exports 2 be P
3, P wherein
2Pressure approximate P
3The pressure that+spring 6 is born.Work as P
1During instantaneous increase, enter the pressure liquid stream P of inner chamber
2Greater than P
3The pressure that+spring 6 is born, at this moment balance flap 16 is moved by the pressure of instantaneous big flow to dwindle the last lower channel of flow of liquid and drive piston 11 pressure springs 6, limited because of P vertically upward
1The pressure increasing flow enters inner chamber, makes P
2=P
3The pressure that+spring 6 is born has kept constant compression force poor, and flow reaches constant; Work as P
1Descend or P
3When resistance increases, P
3The pressure that+spring 6 is born is greater than P
2, at this moment piston 11 moves downward, and the balance flap 16 that drives piston shaft 12 lower ends move vertically downward, and at this moment liquid flowing channel has been opened greatly in the upper edge 8 of balance flap 16 and lower edge 9, at this moment P
2Pressure increases, and makes P
3Pressure=P that+spring 6 is born
2, still kept constant compression force poor, and flow reaches constant.
Owing to pass through the enforcement of the constant flow regulator of this switch valve, can carry out Automatic Fine Tuning to the pressure liquid stream by this switch valve in the pipeline network system, feasible fluid flow by this switch valve reaches stable constant current effect, solved the uneven permanent problem of the flow that fluid flow causes because of pressure reduction changes in the pipeline network system, guarantee the riding quality of flow of liquid, reached purpose of design.
Be further described below in conjunction with the accompanying drawings:
Fig. 1 is the main structure schematic representation that this constant flow regulator is installed in a kind of switch valve body;
Fig. 2 is that Fig. 1 switch valve body shows the fixedly structural representation of valve block 7;
Fig. 3 is the structural representation that shows adjustment disk 17 positions on the switch valve valve gap;
Fig. 4 is the structural representation of valve block 3;
Fig. 5 discloses a kind of structural representation of constant flow regulator of the switch valve that has a drainage device;
Be described below in conjunction with the accompanying drawings: said piston shaft 12 can manufacture one with balance flap 16, guarantees the stability and the degree of regulation of its vertical operation; Guide pad 10 on the piston shaft 12 can be made the geometric figure except that round platform, for example guide pad 10 can be able to be made square.Foursquare limit of guide pad and hollow shaft inwall constitute the power fluid passage that promotes piston 11 upstream or downstream.Said piston 11 can be the manufactured good of epithelium; It also can be the composite article of metal epithelium.
