Embodiment 1

[0022] Example 1, as attached figure 2 And image 3 As shown, the solenoid valve diaphragm includes a diaphragm body 3 and a diaphragm mounting ring body 4. The diaphragm body 3 is in the shape of a bowl that can bulge upwards or dent downwards when stressed, and a diaphragm mount is integrally fixed on the outer edge of the diaphragm body 3. The ring body 4 is provided with a sealing rib 19 overlapping the diameter line of the diaphragm body 3 on the lower side of the diaphragm body 3. The solenoid valve diaphragm is in the shape of a bowl that can bulge upwards or sag downwards when subjected to force. It is flexible and easily lifts up to open the fluid channel inside the valve body at low flow and low pressure, and has strong elasticity and plasticity. , Instantly return to the original state; when the solenoid valve diaphragm is stressed, the sealing rib 19 can be raised or recessed to seal the valve body. It has a better sealing effect on the internal fluid passage of the...

Embodiment 2

[0023] Embodiment 2, as an optimization of Embodiment 1, the cross-section of the sealing rib 19 is polygonal or circular as required. The shape of the sealing rib 19 can be selected according to the needs of processing and implementation.

Embodiment 3

[0024] Example 3, as attached figure 1 As shown, the low-head hydraulic solenoid valve using the solenoid valve diaphragm described in Embodiment 1 or Embodiment 2 includes an upper cover, a solenoid valve diaphragm, a valve body, a compression spring 12 and a three-way valve 15; the upper cover includes an upper cover The cover body 1 and the upper cover mounting ring body 2. The upper cover body 1 is in the shape of an inverted bowl, and the upper cover mounting ring 2 is integrally fixed on the outer edge of the upper cover body 1; the valve body includes the valve body 5 and the water inlet The connecting pipe 6 and the water outlet connecting pipe 7, the valve body 5 is in the shape of a tube with a mounting port 8 matching the diaphragm body 3 at the upper end. The valve body 5 corresponding to the mounting port 8 and perpendicular to the axis of the valve body 5 is provided with a sealing rib 19 that can be tightly sealed The fitted curved boss 9 is fixedly installed at t...

Abstract

The invention relates to the technical field of hydrodynamic control valves, in particular to a low-water-head hydrodynamic solenoid valve. The low-water-head hydrodynamic solenoid valve comprises an upper cover, a solenoid valve diaphragm, a valve body, a compression spring and a three-way valve, wherein the upper cover comprises an upper cover body and an upper cover mounting ring body; the upper cover body takes the shape of an inverted bowl; and the upper cover mounting ring body is integrally fixed at the outer edge of the upper cover body. A solenoid valve diaphragm has flexibility, can easily jack up and open a fluid channel in the valve body under the conditions of small flowrate and low pressure, and sealing and reinforcing rubs have a better function of sealing the fluid channel in the valve body. The structure is reasonable and compact, the use is convenient, the working pressure ranges from 0.3 MPa to 1.0 MPa, the demand for low-pressure and small-flowrate automatic irrigation of vast areas is well satisfied, actual use tests show that the effect is remarkable and great development is brought for vast agricultural automatic irrigation, besides, mounting and dismounting are convenient and quick, the maintenance can be conveniently implemented and the sealing reliability is high.

Description

Technical field [0001] The invention relates to the technical field of hydraulic control valves, and is a solenoid valve diaphragm and a low-head hydraulic solenoid valve. Background technique [0002] Agricultural irrigation is the foundation of agriculture, especially in the arid and water-deficient areas in the northwest. Irrigation has become an important engineering measure for high-efficiency water use in agriculture, stable production of crops, and increased production. Irrigation automation developed on this basis is an important way to transform irrigation methods, improve water-saving irrigation levels, and realize irrigation modernization. At present, in this system, the field control valves used, including the most advanced Israeli hydraulic solenoid valve, etc., usually have a working pressure above 1.5 MPa to work normally. However, in the actual production of a wide range of farmland irrigation systems It is difficult to meet this requirement, making the existing f...
