Description
Technical field
The utility model relates to a kind of valve, specifically, relates to a kind of stealthy valve that is applied on the liquid fertilizer fertilizer apparatus.
Background technique
Operating cost is low, nutrient content is high owing to having, it is compound to be easy to for liquid fertilizer, can be directly absorbed, be convenient to the plurality of advantages such as rational application of fertilizers (balance fertilizing) and mechanized application by crops, more and more receives people's concern.But at present the liquid fertilizer fertilizer apparatus that uses of people exists the shortcoming that fertilising inconvenient operation, fertilising efficient are low, be difficult to control dose.
The model utility content
The purpose of this utility model is to provide a kind of stealthy valve that is applied on the liquid fertilizer fertilizer apparatus, solves above technical problem.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of stealthy valve comprises valve body and spool, it is characterized in that: also comprise the nut that is provided with through hole in the middle of, described nut is provided with internal thread and outside thread; Described valve body and spool are all the cylindrical structures of inner hollow, and all are provided with an outward extending outer rim in border on their top; One end opening of described valve body, the other end sealing, its top is fixedly installed with externally threaded swivel nut, and the shell wall of bottom is provided with liquid entering hole; Described spool is arranged in the inner chamber of valve body, and its length is greater than the top of valve body and the distance between the liquid entering hole minimum point; The inner of described spool is provided with inner opening, and its top is provided with liquid outlet; Described valve body runs through nut, and the internal thread of nut is complementary with the outside thread of swivel nut and is threaded.
Say further, under the outer rim on described valve body top, square set has seal ring No. one; Under the outer rim on described spool top, square set has seal ring No. two.
Furtherly, described spool is the cylindrical structure of up/down perforation, and its outer end is provided with outward opening, is described liquid outlet; Perhaps, the sealing of the outer end of described spool, the shell wall on its top is provided with side opening, is described liquid outlet.
Again furtherly, the outer wall of described spool is provided with outside thread, and the inwall of described valve body is provided with internal thread, and the mode that described spool is threaded connection is arranged in the inner chamber of valve body; Perhaps, described spool is plugged in the inner chamber of described valve body, the inwall Spielpassung of the outer wall of described spool and described valve body.
Beneficial effect: the utility model can be applicable on the liquid fertilizer fertilizer apparatus, can simplify the fertilising operation of liquid fertilizer, improve fertilising efficient, the degree of depth that can also enter by adjusting spool valve body is come the regulated fertilization amount, and, do not applying fertilizer when operation, valve body and spool are can whole retraction liquid fertilizer fertilizer apparatus inner, have hidden function.
Description of drawings
Fig. 1 is embodiment's 1 described in the utility model structural representation;
Fig. 2 is embodiment's 3 described in the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
With reference to Fig. 1, the described a kind of stealthy valve of the present embodiment comprises valve body 1, spool 6 and the middle nut 3 that is provided with through hole, and described nut 3 is provided with internal thread and outside thread.Described valve body 1 and spool 6 are all the cylindrical structures of inner hollow, and all are provided with an outward extending outer rim in border on their top.One end opening of described valve body 1, the other end sealing, its top is fixedly installed with externally threaded swivel nut 4, and the shell wall of bottom is provided with liquid entering hole 2.Described spool 6 is arranged in the inner chamber of valve body 1, and its length is greater than the top of valve body 1 and the distance between liquid entering hole 2 minimum points; The inner of described spool 6 is provided with inner opening 9, and its top is provided with liquid outlet; Described valve body 1 runs through nut 3, and the internal thread of nut 3 is complementary with the outside thread of swivel nut 4 and is threaded.Under the outer rim on described valve body 1 top, square set has seal ring 5 No. one.Under the outer rim on described spool 6 tops, square set has seal ring 7 No. two.
Further, described spool 6 is the cylindrical structure of up/down perforation, and its outer end is provided with outward opening 8, is described liquid outlet.
A nearlyer step ground, the outer wall of described spool 6 is provided with outside thread, and the inwall of described valve body 1 is provided with internal thread, and the mode that described spool 6 is threaded connection is arranged in the inner chamber of valve body 1.
Embodiment 2:
The structure of the present embodiment is compared with embodiment 1, and difference only is: described spool is plugged in the inner chamber of described valve body, the inwall Spielpassung of the outer wall of described spool and described valve body.
Embodiment 3:
With reference to Fig. 2, the structure of the present embodiment is compared with embodiment 1, and difference only is: the outer end sealing of described spool 6, the shell wall on its top is provided with side opening 10, is described liquid outlet.Described spool 6 is plugged in the inner chamber of described valve body 1, the inwall Spielpassung of the outer wall of described spool 6 and described valve body 1.
