Embodiment

[0021] Such as figure 1 As shown, the present invention is an integrated one-way valve with a large flow rate and low starting pressure value, including a valve body 3, which is characterized in that the valve body 3 is radially symmetrical with respect to the liquid flow direction, and a cavity is arranged inside the valve body 3. According to the flow direction of the liquid, there are valve head 1, liquid inlet hole 5, pressure chamber 6, switch device 2, spring 7, and valve seat 4 in sequence in the cavity. The liquid inlet hole 5 is radially located inside the valve head 1, and the valve head 1 is tightly Attached to the inner wall side of the valve body 3, one end of the pressure chamber 6 is connected with the liquid inlet hole 5, and the other end is pressed against the switch device 2, one end of the spring 6 is pressed against the switch device 2, and the other end is pressed against the valve seat 4, and the outlet hole diameter Located inside the valve seat 4, the ...

Abstract

The invention provides a one-piece one-way valve with large flow rate and low starting pressure value. The one-piece one-way valve comprises a valve body which is symmetrical about a radial direction of a liquid flow direction; a cavity is formed inside the valve body; a valve head, a liquid inlet hole, a pressure chamber, a switch device, a spring and a valve seat are arranged in the cavity sequentially in the liquid flow direction; the liquid inlet hole is radially formed in the valve head; the valve head is clung to the inner wall side of the valve body; one end of the pressure chamber is connected with the liquid inlet hole; the other end of the pressure chamber is propped against the switch device; one end of the spring is propped against the switch device; the other end of the spring is propped against the valve seat; the liquid outlet hole is radially formed in the valve seat; and the tail end of the valve seat is connected with a liquid outlet. As the pressure chamber and the valve seat are arranged in the rear of the one-piece one-way valve, the problem that the conventional one-way valve cannot be started and is low in flow rate when pressure is low is well solved.

Description

technical field [0001] The invention relates to a one-way valve, in particular to an integrated one-way valve with large flow rate and low starting pressure value. Background technique [0002] The one-way valve is a device in which the fluid can only flow along the water inlet, but the outlet medium cannot flow back. Check valves, also known as check valves or check valves, are used to prevent reverse flow of oil flow in hydraulic systems, or to prevent reverse flow of compressed air in pneumatic systems. According to structure: lift check valve, butterfly check valve One-way valve, swing check valve; lift check valve: vertical check valve, horizontal check valve; swing check valve: single disc check valve, double disc check valve, multiple Disc check valve. According to the connection form: threaded check valve, welding check valve, flange check valve, check valve has two kinds of straight-through and right-angle, straight-through check valve is installed on the pipeline...
