Pneumatic Ceramic Swing Feed Valve(GZD644TC)

Characteristics:
This valve is applicable for discharge and transportation of dry ash systems in power plants and storehouse pumps, or can be used as an on-off device for pipelines containing abrasive dry ash, water (such as cinder water ) and the like in mines, paper making, chemical engineering and so on, as an on-off for pipelines with both soft grains and corrosive media. Its working nominal pressure is 1.0MPa, applicable temperature is below 200 Deg C, and air supply pressure is 0.6-0.8MPa.

After the valve closed, it's fully sealed in any direction. Its middle body adopts WCB steel casting and seamless steel pipe welding. Its sealing surface adopts a hard sealing element.

Its feed inlet is fully through without any blocks, and it has an automatic compressed air anti-blcikage blowing unit, with strong abrasion resistance, a good sealability, a small starting load and with  little ash sezure of accumulation.

It adopts a high-grade toughened structural ceramic seal, featuring high mechanical strength, strong abrasion resistance, a long service life and a compact structure, which can be installed at any angle.

Special ceramics is different from general ceramics, its hardness even more than steel,
second only to diamond, and corrosion resistant, high temperature resistant!!!!! "" metal
valve with long easy to produce the gap, ceramic valve is not. Because of wear-resisting,
anti-corrosive, sealing strong, ceramic water valve very water saving. "" our valves can be
used 500000 times, if every switch 60 times, can use 22.8 years, this is metal valve can not do it. "

Insecticide Single Formulation

Insecticides can be divided into biological sources and chemical synthesis.
Biogenic insecticides include: â‘  preparations of effective insecticidal ingredients extracted from higher plants, such as natural pyrethrin, rotenone, etc.;
â‘¡ Insecticides made from living organisms mainly include fungi (such as Beauveria bassiana), bacteria (such as odontobacillus) and viruses (such as Bacillus borer).
â‘¢ Insect physiological active substances, such as pheromones.
Chemical synthetic pesticides mainly include: Inorganic insecticides (e.g. White arsenic As2O3, Sodium fluosilicate, Na2SiF6, etc.), organochlorine insecticides (such as chlordane, BHC, DDT, toxaphene, etc.), organophosphorus insecticides (such as dichlorvos, trichlorfon, Dimethoate, malathion, chloraphenone, etc.), carbamate insecticides (such as carbaryl, sulfenocarb, etc.) and pyrethroid insecticides (such as fenvalerate, cypermethrin, etc.).
The main ways in which insecticides can kill pests are:
â‘  Touching agents enter the body through the epidermis of the pest and play a role, causing the pest poisoning and death;
â‘¡ Gastric toxic agents are absorbed by the stomach and intestines directly after being eaten by pests, causing them to die of poisoning;
â‘¢ Some fumigation drugs are volatile, and their vapors enter the body through the respiratory tract of pests, causing them to die of poisoning;
(4) ingestion drugs are first absorbed by the crop, and conducted to the whole plant, when pests ingestion, eating crops, so that it died of poisoning.
