Abstract
The invention relates to a mechanical constant pressure difference control valve of a deuterium gas generator, which comprises an upper cover, a middle ring, a valve needle and a lower valve body, wherein a transfer block is arranged in the middle ring, a spring is arranged in the lower valve body, the valve needle is arranged on the lower valve body and presses the spring, and the upper cover, the middle ring and the lower valve body are sequentially connected. The invention does not need a pressure transmitting and independent actuating mechanism, and meanwhile, the gas output action of constant pressure difference is completed by the valve body, so the invention has simple structure, small volume, sensitive action and small inertia; the deuterium-oxygen valve and the deuterium-oxygen valve mutually acquire pressure signals, and the output action of the interlocking gas is interlocked according to the pressure difference comparison result, so that the pressure difference between the deuterium gas and the oxygen gas is easily kept in a set range, and the fluctuation is extremely small.
Description
Technical Field
The invention relates to a mechanical automatic regulating control valve group for keeping the pressure difference of two different gases constant in a deuterium gas generator gas system, in particular to a mechanical constant pressure difference control valve of a deuterium gas generator.
Background
At present, the traditional domestic water electrolysis equipment for producing hydrogen only has the requirement of zero pressure difference of a hydrogen-oxygen cavity, namely pressure balance, but does not have the pressure of 0.5-1 kgf/cm2The requirement of constant pressure difference. Therefore, the existing gas pressure difference balancing devices convert the pressure difference between different gases into an electrical signal, and then perform corresponding balancing operation by another actuator according to the output electrical signal. Has the defects of large volume, complex structure, large action inertia, frequent fluctuation of balance points and the like.
Disclosure of Invention
The invention mainly overcomes the defects in the prior art, provides a mechanical constant pressure difference control valve of a deuterium gas generator, directly compares gas pressure difference signals, outputs mechanical actions and is executed by a valve group, and one gas is emptied properly according to a pressure comparison result to maintain the constant pressure difference. Compared with the traditional pressure balancing device, the invention has the characteristics of small volume, simple structure, sensitive action, small inertia, extremely small pressure difference fluctuation and the like.
The technical scheme provided by the invention for solving the technical problems is as follows: the deuterium gas generator mechanical constant pressure difference control valve comprises an upper cover, a middle ring, a valve needle and a lower valve body, wherein a transfer block is arranged in the middle ring, a spring is arranged in the lower valve body, the valve needle is arranged on the lower valve body and presses the spring, and the upper cover, the middle ring and the lower valve body are sequentially connected.
The further technical proposal is that a compensation spring is arranged in the upper cover.
The further technical scheme is that sealing elements are arranged between the upper cover and the middle ring and between the middle ring and the lower valve body.
The further technical scheme is that the sealing element is a sealing diaphragm.
The invention has the following advantages: the invention does not need a pressure transmitting and independent actuating mechanism, and meanwhile, the gas output action of constant pressure difference is completed by the valve body, so the invention has simple structure, small volume, sensitive action and small inertia; the deuterium-oxygen valve and the deuterium-oxygen valve mutually acquire pressure signals, and the output action of the interlocking gas is interlocked according to the pressure difference comparison result, so that the pressure difference between the deuterium gas and the oxygen gas is easily kept in a set range, and the fluctuation is extremely small.
