Inclined type pressure regulating valve, manufacturing method and application method

Abstract

The invention relates to an inclined type pressure regulating valve, a manufacturing method and an application method. The inclined type pressure regulating valve consists of a valve body, a valve spool assembly and a valve bonnet, a valve body upper opening of the upper portion of the valve body is inclined to one end of a water inlet, the valve spool assembly consists of a sealing pressure ring, a pressure spring, an adjusting gland, a pressure regulating driving rod, a spring seat fastening bowl, a positioning nut, a fine-adjustment flexible sealing bowl, a valve spool main body, a valve spool connecting screw rod, a sealing rubber ring, a supporting rod, a gasket, a sealing gasket, a valve top and a locking nut, the valve spool assembly is locked by the positioning nut and the lockingnut via the valve spool connecting screw rod, the upper portion of the valve spool main body is a pressure regulating cavity, the lower portion of the valve spool main body is a flow control cavity, and pressure regulation is realized via the pressure regulating cavity and the flow control cavity. The inclined type pressure regulating valve is scientific in design, reasonable in structure, reliable in performance, low in cost, simple in manufacture and favorable for production, and is impact-resistant, ageing-resistant, non-toxic, corrosion-resistant and antioxidant, components are compact, and automatic adjustment of water pressure is realized by water pressure of a water source. In addition, the inclined type pressure regulating valve is widely applied to agricultural water saving irrigation, is particularly used for slopes and mountainous areas, saves a large quantity of investment, and can also be used for water delivery fields with severe requirements on water pressure.

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. Once the pressure of the water source of the water inlet fluctuates, the water pressure of the water inlet increases, and the water flow of the outlet is decreased.The water pressure of the water inlet decreases, and the flow of the water outlet is also i...

AI Technical Summary

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.
