Hardware Knowledge Hall: Ming pole valve and dark bar gate valve difference

Gate valve according to the structure of the valve stem can be divided into: 1, open rod valve: stem nut in the valve cover or bracket, opening and closing the gate, the use of rotating stem nut to achieve stem lifting. This structure is beneficial to the lubrication of the valve stem, opening and closing a clear degree, it is widely used. 2, dark bar gate valve: stem nut in the valve body, and the media in direct contact. Open and close the gate, the rotary valve stem to achieve. The advantage of this structure is that the height of the gate valve always remains unchanged, so the installation space is small, suitable for large-caliber or gate valves with limited installation space. This structure should be equipped with an opening and closing indicator to indicate the degree of opening and closing. The disadvantage of this structure is that not only is the stem thread unlubricated, but it is also subject to direct media erosion and damage. The main difference: 1, dark rod flange valve lifting screw is only rotating without moving up and down, exposing just a rod, the nut is fixed on the gate, through the screw rotation to improve the gate, there is no visible Of the gate; flange rod valve lifting rod is exposed, the nut close to the hand wheel and is fixed (no rotation nor axial movement), by rotating the screw to lift the gate, screw and gate only relative Rotation without relative axial displacement, the appearance of a gantry. Imported pump Castel wine valve 2, dark rod valve is invisible to the screw, and Ming rod is able to see the screw. 3, the dark rod valve in the steering wheel and the stem is connected together relatively fixed, it is through the valve stem at a fixed point to move the valve to promote upward and gate to complete the opening and closing. Ming rod valve is through the stem and steering wheel thread drive to raise or lower the valve. The simple point is to say that the valve rod is the valve stem together up and down movement, the steering wheel is always at a fixed point. This article Keywords: gate valve

Organic chicken manure production line

 

The fresh chicken manure which discharged from broiler farm, layer farm is very large amount, how to right treat these large amount of manure is an urgent task for all poultry farmers. According to clients request, we expansion the poultry project into chicken manure organic fertilizer, which not only solve the problem for clients, but also greatly generate the profit from whole poultry project.

 

The chicken manure fertilizer production line is use fresh chicken manure as raw material, and after serial of processing, and get products of natural organic fertilizer. There are two stage for processing the chicken manure into commercial organic fertilizer, which first is pre-fermentation, and second is with serial processing like grinding the material, filter, mixing, pelleting, drying, cooling, filter, coating, packing -.

 

The features of chicken organic fertilizer

 

1.       There is no any chemical parts, due to chicken digest ability is low who just digest 25% of nutrients in chicken feed, and other 75% of nutrients are goes away with manure, which manure organic fertilizer contains rich nitrogen, phosphorus, potassium, organic meter, amino acid, protein and so on.

2.       The organic matter in fertilizer enhance the organic matter contain in soil. Organic matter improve physical, chemical, and biological properties of soil.

3.       The organic manure in chicken manure not only adds a lot of organic colloids, but also decomposes and convert many organic compounds into organic colloids with the help of microorganism, which greatly increases soil adsorption and produces a lot of sticky material, which makes the soil particles cemented into stable pellet structure, and improves the soil water conservation and fertilizer conservation. Breathability and ability to regulate soil temperature.

4.       The organic manure of chicken manure also make a large number of microorganisms in the soil, especially many beneficial microbes, such as nitrogen fixing bacteria, ammoniated bacteria, cellulose decomposing bacteria, nitrifying bacteria and so on. The organic chicken manure contains all kinds of active enzymes secreted by the digestive tract of animals, and various enzymes produced by microbes. After these substances are applied to the soil, the enzyme activity of the soil can be greatly improved.

5.       Organic chicken manure improve soil activity and biotransformation ability, thereby enhancing soil absorbability, buffer performance and stress resistance.

 

There three models of chicken manure production line:

High Standard:  manure dehydrator, fermenting dumping machine, grinder, mixer, pelleting, drying, cooling, filter, coating, packing, and belt conveyors-etc.

Middle standard: raw material grinder, mixer, pelleting, drying, cooling, filter, packing, and belt conveyors-etc.

Low standard: raw material grinder, mixing, pelleting or filter, packing.
