Micro Sprinkler System

It is in the nozzle above the rocker shaft, set with a front end with a deflector plate (baffle) and guide plate rocker pressure water from the nozzle of the nozzle when sprayed, the deflector plate impact guide plate, so that the rocker arm produces tangential motion force around the cantilever rotation of an angle, and then return under the action of the torsion spring and hit the nozzle, so that the nozzle turn an angle, and so on repeatedly, the nozzle can make a full-circle rotation. If the nozzle is equipped with a limiting device and a reversing mechanism, so that the nozzle in the rotation of a certain angle after the reversal of rotation, you can carry out fan sprinkler irrigation. Suitable for fixed medium pressure sprinkler systems. Vertical pendulum sprinkler head Using the reaction force generated when the water impacts the deflector at the front of the vertical pendulum arm to make the sprinkler head rotate intermittently, the pendulum arm is rotated by the counterweight at its back end. After a certain angle of rotation of the nozzle, by the yoke roller and limiter with the drive rod to push and pull the nozzle in front of the reversing arm, so that it cuts into or out of the nozzle jet, forcing the nozzle to quickly reverse. This nozzle has the advantages of balanced forces, reliable work balance, long range, large range of flow adjustment, etc., the use of increasingly widespread. However, the required pressure is higher and the structure is more complex.

Carbon steel pipe fittings groove fittings surface should be flat, clean, there should not affect the performance of porosity, sand eyes, slag, cold compartment, shrinkage, cracks and depressions and other defects. Cast groove parts should be free from defects such as bulges and depressions. Grooved fittings should be free from processing defects and knock-on damage. Markings should be clear and rowable.

Carbon steel pipe fittings can be coated with electrophoretic paint, plastic or hot dip galvanising for surface and corrosion treatment, where the electrophoretic paint coating method of trench fittings should not be used for domestic drinking water supply. The dimensions of the trench interface after surface treatment shall conform to the provisions of Appendix C of GB/T36019-2018, and the corrosion protection layer shall conform to the following provisions respectively:

 ) paint layer: uniform, smooth, firm, no paint tumor, accumulation of paint, leakage of paint, paint layer thickness of not less than 25.4 &undefined;, paint layer containing less than 0.009% of lead.

b) The plastic layer is uniform, continuous, smooth and firm. Epoxy coating thickness of plastic coated trench fittings should be not less than 130, by mutual agreement between supply and demand, can be specified epoxy coating thickness greater than 130 other thickness of polyethylene coating thickness should be in line with the same nominal size steel-plastic pipe plastic layer thickness requirements in Table 2. The plastic layer should be covered intact at the installation with parts such as the groove of the pipe fittings, and the thickness should be not less than 40 and not affect the installation.

c) hot dip galvanized layer: zinc layer uniform, continuous, smooth, no leakage, zinc layer off, black spots and other defects and rubber ring / pad contact surface should not be zinc tumor, zinc slag, pile of zinc and other appendages zinc layer of lead content of not more than 0.1% zinc layer thickness of not less than 65 .

Carbon steel pipe fittings bolts, nuts should be hot-dip galvanized surface corrosion treatment, and comply with the provisions of GB/T5267.3. Galvanized layer thickness should be not less than 40 galvanized layer surface should be smooth, no leakage, zinc tumor, black spots, no residual solvent slag, oxide inclusions and other defects that damage the intended use of parts performance. Preference shall be given to hot-dipped galvanized bolts and nuts. By mutual agreement between supply and demand, other materials and coated bolts and nuts can be supplied.

The drip head is divided into three basic types according to its energy dissipation characteristics: (1) long runner drip head: the runner diameter is generally less than 1.0mm, length 50~60cm, or even longer, the water flow in the process of overcoming the side wall friction and energy dissipation. (2) Orifice drip head: generally inserted on the capillary tube, inlet and outlet diameter is very small, there is a large cavity in the middle, pressure water flow through the diffusion, contraction or rotation and other ways to consume the remaining energy. (3) Microporous capillary: there are two types of single-walled tubes and double-walled tubes. The former is drip irrigation through the micro-hole on the wall of the tube, the latter has two layers of wall, water from the main wall of the water outlet orifice into the auxiliary cavity, and then by the auxiliary wall of the orifice seepage, the auxiliary wall of the orifice is the main wall of the number of orifices 5 ~ 10 times. This is a special form of capillary pipe which has both water delivery and water discharge functions. It is mostly made of plastic. Due to the small size of the outlet orifice, it is easy to block.

On September 3, the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War, our company organized all employees to watch the grand military parade. The impeccably aligned formations, powerful and rhythmic strides, dignified and heroic troops, and advanced sophisticated equipment filled every employee with immense pride and excitement.


This magnificent parade not only demonstrated the nation’s strong defense capabilities but also highlighted the unity, determination, and uplifting spirit of the Chinese people. Each precise formation reflected countless hours of rigorous training, and every seamless coordination embodied unwavering dedication to excellence. This pursuit of perfection and meticulousness resonates deeply with the professional values we uphold in the water-saving irrigation industry.


Just as the parade exemplified precision and coordination, our company remains committed to providing accurate and efficient irrigation solutions. Every drop of water saved is our response to the national policy of energy conservation and emissions reduction; every optimized irrigation system is our contribution to agricultural development. We understand that water-saving irrigation is not only crucial for agricultural productivity but also integral to national food security and the sustainable utilization of water resources.


Watching the parade has strengthened our determination to contribute to the advancement of national agriculture. Inspired by the spirit of the parade, we will approach our work with even greater passion and professionalism. We are dedicated to developing and producing high-quality water-saving irrigation products, providing robust support for modern agriculture, and contributing to the national cause of water conservation.


In this new era and journey, we, as water-saving irrigation professionals, will stay true to our mission, embrace hard work, and create a brighter future through relentless efforts!
