Problems solved by technology

[0002] At present, the pressure regulating valves used in the market all adopt the metal shell right-angle spring pressure regulating form. The valve body of the pressure regulating valve is made of brass casting process, and its parts are machined. The cost of raw materials is high, the production efficiency is low, and the processing The qualification rate in the process is also low, causing the product price to be too high, affecting its promotion and use, especially affecting the promotion and use of agricultural water-saving irrigation technology
During use, the pressure regulating valve can only set a constant decompression pressure output by one water outlet. Once the pressure of the water source at the water inlet fluctuates, the water pressure at the water inlet increases, and the water flow at the water outlet also decreases. The water pressure at the water inlet decreases, and the water flow at the water outlet also increases. The increase in the water pressure at the water outlet will easily cause the pipeline to burst, which will affect the life of the pipeline at the water outlet.

Description

Technical field [0001] The invention involves a pressure regulation valve, especially a tilt pressure regulating valve and production method and application method. Background technique [0002] At present, the pressure regulating valve used in the market all adopts a right -angle spring regulating form of metal shell. The valve body of the pressure regulating valve adopts a brass casting process.The qualification rate in the process is also low, resulting in high product prices, affecting its promotion and use, and especially affecting the promotion and use of agricultural water saving.During the use process, the pressure regulating valve can only set the constant decompression pressure output of the output of the water outlet.
