Grab the safety medication, pay attention to four protection

First, protect natural enemies. Use selective pesticides to reduce damage to natural enemies. It is forbidden to use pyrethroid pesticides to prevent killing natural enemies and causing pests to re-crack. Because paddy fields are a special ecosystem, multi-species survival, especially the variety of natural enemies, has a good effect on controlling pest populations, especially to protect predatory natural enemies such as spiders, black-shouldered green scorpions and parasitic natural enemies. Small bees, Trichogramma, cockroaches, beetles, etc., give full play to the natural control of natural enemies.

Second, protect the applicators to seriously publicize and train farmers, educate them to pay attention to their own protection, reduce pesticide poisoning, especially in the hot season, educate and guide farmers not to work at high temperatures at noon, while avoiding fatigue operations and protecting the body. health.

The third is to protect crops. Rice is the staple food of the masses. Health quality and safety are the most important. It is necessary to prevent pesticide residue pollution and prohibit the use of highly toxic and high-residue pesticides. At the same time, carefully implement the safety interval to ensure that pesticide residues in rice do not exceed the standard.

The fourth is to protect aquatic organisms. In some areas, rice farming, raising shrimp, raising crabs, and using pesticides should pay more attention to it. In particular, it is necessary to pay attention to controlling the use of flubendiamide to prevent shrimp and crab poisoning. Author: Shao Li

Angle Valves

Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.

Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
