Abstract
The invention relates to an automatic-blockage-eliminating electromagnetic valve, which is characterized by comprises a valve body and a valve spool. The valve body consists of a casing, a bonnet, a cap and an electromagnetic head, the electromagnetic head is arranged at the bonnet, the valve body is provided with a water inlet and a water outlet, the bonnet is arranged on the upper portion of the casing, the cap is arranged on the bonnet, a push-pull electromagnet is arranged in the bonnet, the valve spool consists of a blockage eliminating needle, a positioning part, a spring, a diaphragm, a guide hole, a runner and a filter screen, the blockage eliminating needle is arranged below the push-pull electromagnet, the positioning part and the spring are arranged in the bonnet, the diaphragm is arranged between the bonnet and the casing, the guide hole is arranged on the lower portion of the blockage eliminating needle in the valve spool, the runner is arranged below the guide hole and is in the shape of a bell mouth, and the filter screen is arranged on a water inlet of the runner. Automatic blockage eliminating is realized by the push-pull electromagnet and the blockage eliminating needle which are mounted in the bonnet, and the problem of blockage of common electromagnetic valves is solved by the blockage eliminating technology.
Description
Technical field
The present invention relates to a kind of from the unimpeded solenoid valve.
Background technique
Domestic agricultural irrigation condition of water quality is more abominable, and surface water is generally very dirty, and impurity, suspended matter, the grains of sand are very many, even underground water, still the grains of sand are more in a lot of places.Water quality inclusion granule, impurity are more relatively and hydraulic pressure is unstable, and especially under the long-time obsolete situation of solenoid valve, the pilot hole of solenoid valve is prone to stopped up by mud; The pilot hole design of solenoid valve can not be surpassed under the situation of 3mm by the energy restriction of Electrical heads, and the obstruction of solenoid valve is all at pilot hole, so the pilot hole unimpeded of solenoid valve is imperative; Generally adopt 80 order filters besides, cause the water that flows into solenoid valve generally not reach the solenoid valve requirement like this, excessive particle causes solenoid valve to stop up; When hydraulic pressure is low, more is prone to stop up, thereby causes solenoid valve malfunctioning especially; Can't open and close; Cause a lot of system applies out of condition, do not give full play to its effect, greatly hindered applying of automatic dripping irrigation control technique.
Summary of the invention
The purpose of this invention is to provide a kind of agricultural water conservation that has water self guide driving, low power consumption, anti-blocking, unimpeded, is easy to unpick and wash, keep in repair from the unimpeded solenoid valve.
The objective of the invention is to realize through following technological scheme:
Its characteristics of the present invention are: comprise valve body, spool, described valve body is made up of valve casing, valve gap, bonnet and Electrical heads, and said Electrical heads is located at the valve gap place, plays the keying effect of control solenoid valve; Described valve body is provided with water intake, water outlet, and described valve gap is located at valve casing top, and bonnet is located on the valve gap, is provided with sliding electromagnet in the described valve gap; Described spool is made up of unimpeded pin, locating piece, spring, barrier film, pilot hole, runner and filter screen, and described unimpeded pin is located under the sliding electromagnet, and locating piece is located in the valve gap; The unimpeded pin is positioned, and spring is located in the valve gap, and spool is resetted; Barrier film is located between valve gap and the valve casing, plays a part to regulate hydraulic pressure, and pilot hole is located at the unimpeded pin bottom in the spool; Pilot hole plays guide's water inlet effect, and runner is located under the pilot hole, and runner is horn-like; To prevent that water from refluxing, filter screen is located on the water intake of runner, to getting into the current filtration of runner.
Compared with prior art, the present invention adopts agricultural water conservation automatic irrigation solenoid valve, leans on push-pull electromagnet and the unimpeded pin installed in the valve gap to realize automatically tackling blockage; Adopt this unimpeded technology, adopt 80 purpose filter screens to irrigate 100 hours, can guarantee that the solenoid valve plugging rate is no more than 1%; Under the low hydraulic pressure of 0.05MPa, the solenoid valve plugging rate is no more than 5%, for the solenoid valve that stops up; Peasant household can repair in 10 minutes, made China's water-saving irrigation solenoid valve design, made and can catch up with the developed countries, and magnetic valve performance reaches world-class levels; Realize the production domesticization of field irrigation automation control electromagnetic valve, significant to applying of automatic irrigation technology.
