Problems solved by technology

[0008] Although the direct-acting piston type pressure reducing and stabilizing valve with this structure can achieve a certain degree of pressure reducing and stabilizing effect, but only the piston 6' is a pressure regulating part and limited by the volume and spring stiffness, the outlet pressure will still be relatively high. Large fluctuations, in occasions with high voltage regulation requirements, cannot meet the needs of higher voltage regulation accuracy

Abstract

The invention relates to the technical field of hydraulic valves, and discloses a pressure reduction and stabilization valve. The pressure reduction and stabilization valve comprises a valve housing; a liquid inlet and a liquid outlet are respectively formed at the two ends of the valve housing; a first sensing element and a second sensing element are arranged between the liquid inlet and the liquid outlet; the liquid channels of the first sensing element and the second sensing element are respectively communicated with the liquid inlet and the liquid outlet; the stressed part of the first sensing element is arranged opposite the stressed part of the second sensing element; a pressure cavity is formed between the two stressed parts; the pressure cavity is communicated with both the fluid channel of the first sensing element and the fluid channel of the second sensing element. The pressure reduction and stabilization valve has high pressure stabilization accuracy, and can be used at the occasions having high requirements for pressure stabilization.

Description

Technical field [0001] The invention relates to the technical field of hydraulic valves, in particular to a pressure reducing and stabilizing valve with more stable stabilizing characteristics. Background technique [0002] In the usual cold and hot water pipe network, the power of the water network is provided by the water pump. Due to the fluctuation of the water pressure output by the water pump and the opening and closing of various appliances in the water network, the water pressure in the water network will fluctuate, which will damage Even destroy the appliances in the water network. [0003] In order to solve the above problems, a pressure reducing and stabilizing valve is usually installed in the water network to reduce the fluctuation of water pressure in the water network. The pressure reducing and stabilizing valve uses the energy of the fluid itself to act on the specific sensitive components of the valve body to drive the movement of the valve disc, realize the autom...
