The utility model discloses a control valve with back-suction function. The valve body is equipped with a main control valve capable of controlling the opening and closing of the liquid inlet pipeline and the liquid outlet pipeline. The main control valve is a three-way main control valve, which is located at At the intersection of the liquid inlet pipeline, the liquid outlet pipeline and the liquid return pipeline, a suction flow channel and a bypass valve are also provided in the valve body. One end of the suction flow channel is connected with the liquid outlet pipeline, and the other end is connected with the The return pipeline is connected, and the bypass valve is located in the return suction flow channel. The utility model utilizes the negative pressure generated by the backflow of the medicinal liquid at the nozzle to suck back the medicinal liquid in the liquid outlet pipeline, thereby effectively eliminating the phenomenon of pesticide dripping, avoiding waste, and ensuring that the environment is not polluted. After popularization, there will be Good social and economic benefits.
Description
The utility model relates to a kind of valve, especially a kind of control valve that is installed in the liquid flow tube road.
At present, the main control valve that can control feed liquor pipeline and fluid pipeline break-make is housed in the valve body of known control valve.When main control valve was shown in an open position, the feed liquor pipeline communicated with the fluid pipeline; When main control valve was in the closed position, feed liquor pipeline and fluid pipeline turn-offed.This control valve is installed in the atomizer passgae of spraying insecticide, when being used to control pesticide spraying, has no progeny because main control valve closes, still there is certain overbottom pressure in the fluid pipeline that is communicated with shower nozzle, so the dropping liquid phenomenon is obvious.The result not only can cause the waste of agricultural chemicals, but also can cause environmental pollution, will bring disaster to people's life health when serious.
The purpose of this utility model is: be applied to the problem that pesticide spraying exists at above-mentioned existing control valve, propose not have when a kind of main control valve turn-offs the control valve of inhaling function of taking back of dropping liquid phenomenon, thereby avoid waste, keep environment not contaminated.
In order to achieve the above object, the utility model is taken back in the valve body of inhaling the function control valve main control valve that can control feed liquor pipeline and fluid pipeline break-make is housed, this main control valve is the threeway main control valve, be positioned at feed liquor pipeline, fluid pipeline, liquid return pipe road intersection, therefore also have the function of control feed liquor pipeline and liquid return pipe road break-make.In addition, also be provided with resorption runner and bypass valve in the valve body, an end of described resorption runner and fluid pipeline connection, the other end is communicated with the liquid return pipe road, and described bypass valve is arranged in the resorption runner.
It is also to contain controlling rod that the utility model further improves, and described controlling rod links to each other with bypass valve with main control valve simultaneously.
When the utility model is taken back the control valve of inhaling function and is used for control and sprays insecticide, when main control valve is opened, when bypass valve turn-offs, the feed liquor pipeline communicates with the fluid pipeline, the shower nozzle spray pesticide.When the switching controlling rod makes the main control valve transposition, the feed liquor pipeline is communicated with the liquid return pipe road, bypass valve is opened simultaneously, the fluid pipeline is communicated with the liquid return pipe road through the resorption runner, and soup flows into the liquid return pipe road by the feed liquor pipeline as a result, produces negative pressure in the spout place, with the soup resorption in the fluid pipeline, thereby effectively eliminated the agricultural chemicals weeping, both avoided waste, guaranteed free from environmental pollution again.To produce good social benefit and economic benefit after promoting.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is an embodiment's of the utility model an atomize structural representation.
Fig. 2 is Fig. 1 embodiment's a resorption status architecture schematic representation.
Take back the liquid return pipe road 4, the resorption runner 11 that are provided with feed liquor pipeline 6, fluid pipeline 10, band convergent spout 3 in the valve body 1 of inhaling the function control valve among Fig. 1 and Fig. 2, and main control valve 7 and bypass valve 2 be housed, one end of resorption runner 11 is communicated with fluid pipeline 10, the other end is communicated with liquid return pipe road 4 near convergent spout 3, produces negative pressure when so more helping back liquid.In addition, the fluid pipeline 10 of valve body 1 also communicates with liquid return pipe road 4 through voltage stabilizing runner 8, and the safety valve 9 of overpressure protection effect has been housed in the ingress of voltage stabilizing runner 8.Main control valve 7 is used to control the break-make on feed liquor pipeline 6 and fluid pipeline 10 and feed liquor pipeline 6 and liquid return pipe road 4, and bypass valve 2 is contained in the resorption runner 11, is used to control the break-make on resorption runner 11 and liquid return pipe road 4.Controlling rod 5 links to each other with bypass valve 2 with main control valve 7 simultaneously, makes both interlocking interlocks.
During normal spray operation, present embodiment take back inhale the function control valve the break-make situation as shown in Figure 1, this moment main control valve 7 with feed liquor pipeline and fluid pipeline connection, bypass valve 2 shutoffs, feed liquor pipeline 6 communicates with fluid pipeline 10, the shower nozzle spray pesticide.When counterclockwise switching controlling rod 5 nine ten is spent, the break-make situation as shown in Figure 2, main control valve 7 transposition, bypass valve 2 are opened, feed liquor pipeline 6 communicates with liquid return pipe road 4, while fluid pipeline 10 communicates with liquid return pipe road 4 through resorption runner 11.Experiment showed, that in the case soup flows into the liquid return pipe road by the feed liquor pipeline, produce negative pressure near convergent spout 3, with the soup resorption in the fluid pipeline 10, the result has realized that moment do not have water clock and turn-off, both avoided waste, and guaranteed that again environment was not contaminated, effect is very remarkable.
