Description

Technical Field

[0001] The utility model relates to a solenoid valve structure. Background Art

[0002] Prior art, such as Chinese utility model patent document, application number 202323631724.X, records a pulse large flow anti-water hammer slow closing pipeline valve, characterized in that it includes: a solenoid valve head, a positioning plate, a fixed seat, a return spring, a floating seat and a rubber membrane; the fixed seat extends a sliding rod from the inside, the rubber membrane and the fixed seat are combined to form a valve cavity, the return spring is arranged in the valve cavity and elastically abuts between the fixed seat and the floating seat; the floating seat is provided with a water flow channel; the return spring is provided with a valve needle that cooperates with the water flow channel to switch between an open state or a closed state.

[0003] Based on the above, in the prior art, a slide bar is arranged on the fixed seat, and the function of the slide bar is to form a flow channel inside. When the valve head is in the open state, the water in the valve cavity can flow out along the flow channel inside the slide bar through the center hole. Although this flow channel setting can achieve drainage, since the floating seat is made of rubber material and is tightly sleeved on the slide bar, friction occurs between the floating seat and the slide bar during the floating process. This friction affects the stability of the floating seat movement and affects the water on / off function of the solenoid valve under low water pressure conditions, which needs further improvement. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a solenoid valve structure that eliminates the sliding rod and avoids friction affecting the moving stability of the floating seat.

[0005] A solenoid valve structure designed for this purpose includes a fixed seat, a diaphragm assembly and a valve head, wherein a water storage cavity with a lower end opening is arranged in the valve seat, the diaphragm assembly is arranged at the lower side of the water storage cavity and connected to the fixed seat, the diaphragm assembly is provided with a water inlet hole connected to the water storage cavity, the valve head is installed on the upper surface of the fixed seat, the upper surface of the fixed seat is provided with a drainage cavity, the fixed seat is provided with a first flow channel connected to the drainage cavity and the water storage cavity, and the fixed seat above the water storage cavity is provided with a drainage channel and a second flow channel;

[0006] One end of the second flow channel is connected to the drainage cavity, and the other end is connected to the drainage channel. One end of the drainage channel away from the second flow channel passes through the fixing seat and is opened outward.

[0007] The telescopic end of the valve head extends into the drainage cavity and blocks one end of the second flow channel communicating with the drainage cavity.

[0008] Preferably, a spring is provided in the water storage chamber, one end of the spring abuts against the top surface of the water storage chamber, and the other end of the spring abuts against the diaphragm assembly.

[0009] Preferably, a pass pin is provided on the spring, and the pass pin is movably inserted into the water inlet hole.

[0011] Preferably, the drainage channel is a flow channel that passes through the fixing seat from left to right, and both left and right ends thereof are opened.

[0012] Preferably, the drainage channel and the second flow channel are arranged perpendicular to each other.

[0013] Compared with the prior art, the utility model has a drainage cavity on the upper surface of the fixed seat, a first flow channel connected to the drainage cavity and the water storage cavity on the fixed seat, and a drainage channel and a second flow channel on the valve seat above the water storage cavity; one end of the second flow channel is connected to the drainage cavity, and the other end is connected to the drainage channel, and the end of the drainage channel away from the second flow channel passes through the fixed seat and is opened outward; the telescopic end of the valve head extends into the drainage cavity and blocks the end of the second flow channel connected to the drainage cavity. The utility model provides the second flow channel and the drainage channel on the fixed seat, so that when the valve head is opened, the water in the drainage cavity can be discharged through the second flow channel and the drainage channel, thereby achieving drainage while eliminating the slide rod. The elimination of the slide rod can avoid friction between the diaphragm assembly and the diaphragm assembly, eliminating the hidden danger of the solenoid valve's water on and off function under low water pressure conditions.
