Description
Technical field
The present invention relates to a kind of double system pressure adjustment technology, relate in particular to the valve body that double system pressure adjustment is realized in a valve.
Background technique
The hydrogen of water electrolysis hydrogen producing system, the difference of liquid level of oxygen separator only allow in less amplitude.Employing at present gathers respectively the pressure of both sides, through PLC, calculates, and controls the modulating valve of both sides to reach balance, and so operation, comparatively loaded down with trivial details, and cost is higher.
Summary of the invention
Defect in view of above-mentioned prior art exists, the objective of the invention is to propose a kind of double system equilibrium valve.
Double system equilibrium valve of the present invention is achieved through the following technical solutions: a kind of double system equilibrium valve, especially, described double system equilibrium valve is by valve body, flexible partition, valve rod forms, described flexible partition is located in valve body and is separated the inner chamber of valve body, described valve body is provided with advancing of a gas system of connection in a side of flexible partition, air outlet, and be provided with advancing of another gas system of connection in the another side of flexible partition, air outlet, described valve rod perpendicular to plane, flexible partition place, with the flexible partition one, be connected and the valve rod two ends respectively over against two air outlets of valve body, described valve rod two ends are embedded with respectively between spool and two spools and valve rod and are respectively equipped with the equal pressing spring that drives the outer bullet of spool, spool is servo-actuated with valve rod and connect or separate with the air outlet of respective side.
Further, the end of described spool is made as cone, spheroid or hemisphere.
Further, described equal pressing spring is located between the inboard, end of the end face of valve rod and spool.
Further, described equal pressing spring is located in the cavity of spool and valve rod tabling.
Apply double system equilibrium valve of the present invention, its significant advantage is: adopt pressure ratio that flexible partition realized the both sides gas systems, and can Timing Belt ovable valve stem, spool move the pressure adjustment that carries out gas-discharging type, this equilibrium valve terminal with compact integral structure, without PLC, calculate, with low cost, practical reliable.
The accompanying drawing explanation
Fig. 1 is the structural representation under double system equilibrium valve state of equilibrium of the present invention.
Fig. 2 is the equilibrium valve of double system shown in Fig. 1 at valve element position and the exhaust schematic diagram of A system one side pressure when high.
Fig. 3 is the equilibrium valve of double system shown in Fig. 1 at valve element position and the exhaust schematic diagram of B system one side pressure when high.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
The multimode schematic diagram of double system equilibrium valve of the present invention as shown in Figure 1 to Figure 3, this double system equilibrium valve is by valve body 1, flexible partition 2, valve rod 3 forms, flexible partition 2 is located in valve body 1 and is separated the inner chamber of valve body, valve body 1 is provided with in a side of flexible partition 2 suction port 14 that connects a gas system, air outlet 12, suction port 14 is connected with B system import 61, air outlet 12 is connected with B system outlet 62, and be provided with in the another side of flexible partition 2 suction port 15 air outlets 13 that connect gas A system, suction port 15 is connected with A system import 71, air outlet 13 is connected with A system outlet 72, valve rod 3 perpendicular to flexible partition 2 planes, place, with flexible partition 2 one, be connected and valve rod 3 two ends respectively over against the 12He air outlet, air outlet 13 of valve body 1, valve rod 3 two ends are embedded with respectively between spool 4 and two spools and valve rod 3 and are respectively equipped with the equal pressing spring 5 that drives the outer bullet of spool, spool 4 with valve rod 3 servo-actuated and with the air outlet 12 of respective side, air outlet 13 connects or separates.
In the present embodiment, the end of spool 4 is made as cone, conveniently with 12, air outlet, air outlet 13, docks, seals.Certainly in addition, the machining shape of this end can also be spheroid or hemisphere.
In addition, between the end face that in the present embodiment, all pressing spring 5 is located at valve rod 1 and the inboard, end of spool 4, this equal pressing spring 5 also can be located in the cavity of spool 4 and valve rod 1 tabling in addition.The compress power equilibrium of spool to air outlet when this spring is intended to keep flexible partition 2 skew, the erroneous judgement while avoiding the two ends air pressure balance.
For optimizing the present invention, the double system equilibrium valve has also been set up anti-leakage mechanism 11, prevents that the double system equilibrium valve from leaking.
The working principle of a kind of double system equilibrium valve of the present invention: the double system equilibrium valve docks with two gas systems, for convenience of setting forth, therefore two gas systems are defined as to A system and B system, as shown in Figure 1, when A system and B system gas pressure balanced, flexible partition 2 mediates, and does not produce displacement, and valve rod 3 two ends spools 4 offset with corresponding air outlet; As shown in Figure 2, when A system air pressure is greater than B system air pressure, flexible partition 2 is offset towards the B system side, flexible partition 2 actuate valve stem 3 also are with movable valve plug 4 to separate with respective side air outlet 13, in the first system, gas is discharged by air outlet 13 and system outlet 72, air pressure returns to flexible partition 2 and resets, and now A system and B system air pressure reach balance; As shown in Figure 3, when A system air pressure is less than B system air pressure, flexible partition 2 is offset towards the A system side, flexible partition 2 actuate valve stem 3 also are with movable valve plug 4 to separate with respective side air outlet 12, in the B system, gas is discharged by air outlet 12 and system outlet 62, air pressure returns to flexible partition and resets, and now A system and B system air pressure reach balance.
By above-mentioned character express, can find out, apply double system equilibrium valve of the present invention, flexible partition is separated into twoth district by body cavity, flexible partition meets in the pressure reduction allowed band and can promote spool and move, thereby the pressure of two systems of balance, device is whole succinct, without adopting traditional PLC to calculate, with low cost, practical reliable.
In addition to the implementation, the present invention can also have other mode of execution, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
