Abstract
The invention discloses a flow adjustable emitter, and relates to an emitter. The invention aims to provide a flow adjustable emitter capable of changing irrigation quantity without replacing the emitter. The technical solution of the invention is that: the emitter comprises a shell and a valve core, wherein the valve plug is matched with a hole of a lower end cover of an upper shell in a sliding way; the center of the upper end face of the valve plug is provided with a cylinder of which the end head is conical, and the cylinder is in clearance fit with a vertical water inlet hole in the center of an upper end cover of the upper shell; the end face of the valve plug is provided with an elastic sealing plate; a spring is arranged outside the valve plug between a lower end face of a step at the upper end of the valve plug and the lower end cover of the upper shell; the lower end of the valve plug is provided with an annular groove which is in sliding fit with an annular solid at the upper end of a limit cylinder on a lower end plate of a lower shell; and a longitudinal hole in the limit cylinder is communicated with a longitudinal hole of the valve plug. The flow adjustable emitter is suitable for farmland irrigation.
Description
Technical field:
The present invention relates to the douche of a kind of douche, particularly a kind of adjustable flow.
Background technology:
Drip irrigation is the good irrigation method of a kind of water-saving result and being widely used, but, the operating pressure of existing douche and irrigating water quota generally can not change, but, crop is inequality at different growth periods to the demand of water, when crop need change output, can only realize by changing douche, increased the manpower of irrigating cost and changing douche.
Summary of the invention:
The purpose of this invention is to provide a kind of douche that douche can realize changing the adjustable flow of irrigation quantity of not changing.Technical solution of the present invention is, comprise housing and spool, it is characterized in that: the spool cunning fits in the bottom end cover hole of upper shell, be provided with the vertical inlet opening matched in clearance at the upper end cover center of cylinder that the termination is a cone and upper shell in the center of spool upper surface, be provided with the elastic packing plate of concave upright arc on the spool end outside this cylinder, this elastic packing plate is less than the intracavity diameter of upper shell, be provided with spring outside the lower surface of the step on spool and the valve core between the upper shell bottom end cover, the top of valve core is provided with radial hole and is communicated with the inner chamber of upper shell and vertical hole of spool bottom, the lower end of valve core is provided with cannelure joins with the annular solid cunning that is connected in the spacing cylinder upper end on the lower house bottom plate, and the interior vertical hole of the vertical hole in this spacing cylinder and valve core is connected.The present invention has compared with the prior art and does not change the remarkable advantage that douche can realize changing duty.
Description of drawings:
Accompanying drawing is the douche structural representation of adjustable flow of the present invention.
The specific embodiment:
In conjunction with above accompanying drawing the present invention is described in detail, on the upper end cover of upper shell 2, be provided with the ozzle 1 that is connected with water supply hose, the center of this end cap is provided with vertical inlet opening and is communicated with the inner chamber of ozzle and upper shell, spool 5 is slided in the hole of the bottom end cover that fits over upper shell, spring 4 places outside the step body inner face and the valve core between the upper shell bottom end cover inner face of spool termination, the cylinder that to be provided with a termination in the center of the upper surface of valve core be taper is a matched in clearance with the cooperating of vertical hole of the center of upper shell upper end cover, also be provided with the elastic packing plate 3 of a concave upright arc on the upper surface of the spool outside this cylinder, the diameter of this arc elastic plate is less than the diameter of upper shell inner chamber, the bottom of spool places the inner chamber of lower house 6, be provided with a vertical cannelure in the lower end of spool slippery with the annular solid that is connected in cylindrical limit body 7 tops on the lower house bottom plate, the top that is in the spool in the upper shell inner chamber is provided with radial hole and is communicated with the inner chamber of upper shell, and the valve core center below this radial hole is provided with vertical hole and is communicated with the vertical hole 8 at cylindrical limit body center and the radial hole on spool top respectively.
