Background technique
The hydrogen of water electrolysis hydrogen producing system, the difference of liquid level of oxygen separator only allow in less amplitude.Current employing gathers the pressure of both sides respectively, calculates through PLC, and the modulating valve controlling both sides, to reach balance, so operates, comparatively loaded down with trivial details, and cost is higher.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is to propose a kind of Double-system balance valve.
Double-system balance valve of the present invention is achieved through the following technical solutions: a kind of Double-system balance valve, especially, described Double-system balance valve is by valve body, flexible partition, valve rod is formed, described flexible partition to be located in valve body and to be separated the inner chamber of valve body, described valve body is provided with entering of a connection gas system in the side of flexible partition, air outlet, and entering of another gas system of connection is provided with in the another side of flexible partition, air outlet, described valve rod is connected perpendicular to flexible partition place plane and flexible partition one and valve rod two ends are distinguished just to two air outlets of valve body, described valve rod two ends be embedded with spool respectively and two be respectively equipped with the equal pressing spring driving the outer bullet of spool between spool and valve rod, spool is servo-actuated with valve rod and abut against with the air outlet of respective side or be separated.
Further, the end of described spool is set to cone, spheroid or hemisphere.
Further, described equal pressing spring is located between the end face of valve rod and the tip inside of spool.
Further, described equal pressing spring is located in the cavity of spool and valve rod tabling.
Apply Double-system balance valve of the present invention, its significant advantage is: adopt flexible partition to achieve the pressure ratio of both sides gas system comparatively, and energy Timing Belt ovable valve stem, spool move the pressure adjustment carrying out gas-discharging type, this equilibrium valve terminal with compact integral structure, calculate without the need to PLC, with low cost, practical reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation under Double-system balance valve state of equilibrium of the present invention.
Fig. 2 is the valve element position of Double-system balance valve shown in Fig. 1 when A system one side pressure height and exhaust schematic diagram.
Fig. 3 is the valve element position of Double-system balance valve shown in Fig. 1 when B system one side pressure height and exhaust schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail, is easier to make technical solution of the present invention understand, grasp.
The multimode schematic diagram of Double-system balance valve of the present invention as shown in Figure 1 to Figure 3, this Double-system balance valve is by valve body 1, flexible partition 2, valve rod 3 is formed, flexible partition 2 to be located in valve body 1 and to be separated the inner chamber of valve body, valve body 1 is provided with the suction port 14 of a connection gas system in the side of flexible partition 2, air outlet 12, suction port 14 is connected with B system inlets 61, air outlet 12 is connected with B system outlet 62, and suction port 15 air outlet 13 connecting gas A system is provided with in the another side of flexible partition 2, suction port 15 is connected with A system inlets 71, air outlet 13 is connected with A system outlet 72, valve rod 3 is connected perpendicular to flexible partition 2 place plane and flexible partition 2 one and valve rod 3 two ends are distinguished just to air outlet 12 and the air outlet 13 of valve body 1, valve rod 3 two ends are embedded with spool 4 respectively and are respectively equipped with the equal pressing spring 5 driving the outer bullet of spool between two spools and valve rod 3, spool 4 with valve rod 3 servo-actuated and with the air outlet 12 of respective side, air outlet 13 abuts against or is separated.
In the present embodiment, the end of spool 4 is set to cone, conveniently docks with air outlet 12, air outlet 13, seals.Certainly in addition, the machining shape of this end can also be spheroid or hemisphere.
In addition, in the present embodiment, equal pressing spring 5 is located between the end face of valve rod 1 and the tip inside of spool 4, and this equal pressing spring 5 also can be located at spool 4 with the cavity of valve rod 1 tabling in addition.This spring be intended to keep flexible partition 2 when offseting spool isostasy is supported to air outlet, avoid the erroneous judgement during air pressure balance of two ends.
For optimizing the present invention, Double-system balance valve has also set up anti-leakage mechanism 11, prevents Double-system balance valve from leaking.
The working principle of a kind of Double-system balance valve of the present invention: Double-system balance valve is docked with two gas systems, for convenience of setting forth, therefore two gas systems are defined as 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 spool 4 offsets with corresponding air outlet; As shown in Figure 2, when A system air pressure is greater than B system air pressure, flexible partition 2 offsets towards B system side, flexible partition 2 actuate valve stem 3 is also with movable valve plug 4 to be separated 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 offsets towards A system side, flexible partition 2 actuate valve stem 3 is also with movable valve plug 4 to be separated with respective side air outlet 12, in 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.
Can be found out by above-mentioned character express, apply Double-system balance valve of the present invention, body cavity is separated into twoth district by flexible partition, flexible partition meets in pressure reduction allowed band and can promote spool and move, thus the pressure of balance two systems, device is overall succinct, calculates without the need to adopting traditional PLC, 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, all drop within the present invention's scope required for protection.
