Embodiment Construction
[0012] Below in conjunction with the accompanying drawings, the specific embodiments of the present invention will be further described in detail, so as to make the technical solution of the present invention easier to understand and grasp.
[0013] Such as Figure 1 to Figure 3 The multi-state schematic diagram of the dual-system balancing valve of the present invention is shown. The dual-system balancing valve is composed of a valve body 1, a flexible diaphragm 2, and a valve stem 3. The flexible diaphragm 2 is arranged in the valve body 1 and separates the inner cavity of the valve body. The body 1 is provided with an air inlet 14 and an air outlet 12 connected to a gas system on one side of the flexible diaphragm 2, the air inlet 14 is connected with the B system inlet 61, and the air outlet 12 is connected with the B system outlet 62, and in The other side of the flexible diaphragm 2 is provided with an air inlet 15 and an air outlet 13 connected to the gas A system, the ...

The invention provides a double-system balance valve. Especially, the double-system balance valve is characterized by comprising a valve body, a soft membrane and a valve rod. The soft membrane is arranged inside the valve body and divides an inner cavity of the valve body, the part, located on one side of the soft membrane, of the valve body is provided with an air inlet and an air outlet both of which are connected with a gas system, and the part, located on the other side of the soft membrane, of the valve body is provided with an air inlet and an air outlet both of which are connected with another gas system. The valve rod is perpendicular to the plane where the soft membrane is located, and is integrally connected with the soft membrane. The two ends of the valve rod are right opposite to the two air outlets of the valve body respectively, valve elements are embedded into the two ends of the valve rod respectively, pressure-sharing springs are arranged between the valve elements and the valve rod, and the valve elements move along with the valve rod and abut against or separate from the air outlet in the corresponding side. According to the double-system balance valve, the inner cavity of the valve body is divided into two parts by the soft membrane, the soft membrane can push the valve elements to move within the range allowed by the differential pressure, and accordingly the air pressure of double systems is balanced. The overall double-system balance valve is integrally simple, a traditional PLC is not needed to calculate, cost is low, and the device is practical and reliable.
Description
technical field [0001] The invention relates to a dual-system pressure adjustment and balance technology, in particular to a novel valve body in which the dual-system pressure adjustment and balance is realized in one valve. Background technique [0002] The liquid level difference of the hydrogen and oxygen separator of the water electrolysis hydrogen production system is only allowed in a small range. At present, the pressure on both sides is collected separately, and the regulating valves on both sides are controlled to achieve balance through PLC calculation. This operation is cumbersome and costly. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the object of the present invention is to propose a dual-system balancing valve. [0004] The dual-system balancing valve of the present invention is realized through the following technical solutions: a dual-system balancing valve, in particular, the dual-system balancing valve is ...
