Abstract
The present invention relates to a linkage valve. A valve body (1) is provided with an inlet passage (2), an outlet passage (11) and a smooth bore (6) which is communicated with the atmosphere, wherein the inlet passage (2) and the outlet passage (11) are separated by a separation wall (10) with a blocking hole (9); the smooth bore (6) is communicated with the inlet passage (2) and is corresponding to the blocking hole (9); a valve rod (3) passes through the blocking hole (9), one part of the valve rod (3) in the smooth bore (6) is provided with a piston body (4), and the other part of the valve rod (3) at the outlet passage (11) is provided with an end plug (12) which can blocks the blocking hole (9). The present invention is arranged at the input end of a closed type fluid container and can automatically act with the opening or closing action of a valve at the output end of the fluid container.
Description
Technical field
The present invention relates to a kind of valve arrangement, particularly a kind of input end that is installed in the closed type fluid container, and can move and the mechanical type interlock valve of auto-action with this container output terminal valve switch.
Background technique
Proposition of the present invention comes from water-storage enclosed type electric water heater field, existing water-storage enclosed type electric water heater when mounted, its inlet valve is in opening state all the time, the problem that this structure is brought is, inner container of electric water heater (being water storage tank) communicates with intake pipe all the time, under outlet valve is in closed condition, in case water supply pressure excessive (hydraulic pressure of tap water own too high or used suction booster), cause the inner bag mechanically deformation easily, thereby cause and leak.In the prior art, for addressing this problem general employing by the valve sets that the electromagnetic type electric valve more than two is combined into, reach the interlock purpose by electric drive, its complex structure is not easy to again install, control.
Summary of the invention
Purpose of the present invention provides a kind of closed type fluid container input end that is installed in regard to being at the present situation of above-mentioned prior art, and can be with this container output terminal valve switch action the mechanical type interlock valve of auto-action.
The object of the present invention is achieved like this: the interlock valve includes valve body and valve rod, valve body has an inlet passage, an outlet passage and a smooth bore that communicates with atmosphere, the partition wall that described inlet passage and outlet passage are blocked up by a band is separated by, described smooth bore communicate with inlet passage and with described block up relative, described valve rod passes described blocking up, and its part that is positioned at smooth bore has a piston body, and its part that is positioned at outlet passage has one can block the plug of blocking up.
After applying the present invention to electric water heater; as long as a flowing water Valve is arranged to be opened; the interlock valve is just opened thereupon automatically; and when all outlet valves are all closed; the interlock valve also cuts out thereupon, cuts off water inlet automatically, thereby inner bag and intake pipe are isolated, and the hydraulic pressure in the adjusting inner bag is all the time smaller or equal to water feeding pressure; protected inner bag effectively, inner bag life-span and coefficient safe in utilization improve greatly.From structure of the present invention as seen, its application is not limited to the electric water heater field, also can be applicable to other similar field.
Description of drawings
Fig. 1 is the structure cross-sectional schematic of the embodiment of the invention.
Fig. 2 is applied to the structural representation of electric water heater for the present invention.
Embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, the interlock valve includes valve body 1 and valve rod 3, valve body 1 has an inlet passage 2, an outlet passage 11 and a smooth bore that communicates with atmosphere 6, described inlet passage 2 and outlet passage 11 are separated by by block up 9 partition wall 10 of a band, described smooth bore 6 communicate with inlet passage 2 and with described block up 9 relative, described valve rod 3 passes describedly blocks up 9, and its part that is positioned at smooth bore 6 has a piston body 4, its part that is positioned at outlet passage 11 has one can block 9 the plug 12 of blocking up, and plug 12 is being made by sealing material towards 9 the one side of blocking up at least.
For making sealing more reliable, but described piston body 4 periphery wall embedding hoops have seal ring 8, as shown in Figure 1, can certainly adopt other structures, or even whole piston body 4 all adopt sealing material; Piston body 4 can be integrally manufactured with valve rod 3, also can be that split connects.
For making the hydrodynamic pressure in the seal container that the interlock valve is installed adjustable, also can be provided with controlling mechanism in described smooth bore 6 port position, comprise that being enclosed within valve rod 3 outer Regulation springs 5 reaches the adjusting nut 7 that is threaded with smooth bore 6 ports, nut 7 adjustable springs 5 tension force are regulated in rotation, thus the purpose that realizes regulating this container fluid pressure.
Make to install conveniently for making, valve body 1 also can have an opening in the position at described plug 12 places, and seals nut 14 by one and seal, and a sealing gasket 14 linings and are provided with a supporting base 15 that can support plug 12 within it betwixt;
The present invention is when using, the outlet passage 11 of interlock valve and the inlet opening of an airtight fluid container are joined, so the switch motion of this container delivery outlet valve is flowed or is stopped to control opening or closing of interlock valve automatically by fluid: when the delivery outlet valve opening of container, fluid begins to flow, the fluid that rests on interlock valve inlet passage 2 is pushed plug 12 open, this moment, valve rod 3 and piston body 4 thereof inwardly moved along smooth bore 6, fluid by inlet passage 2 through block up 9, outlet passage 11 flows to this container, the interlock valve is in opening state; When the outlet of container valve closing, fluid stops to flow, and piston body 4 outwards moves at the effect lower edge of hydrodynamic pressure smooth bore 6, and plug 12 blocks up 9 towards 9 motions of blocking up until blocking at this moment, and the interlock valve is in closed condition; When hydrodynamic pressure low excessively (even not having fluid), the underpressure of fluid is so that piston body 4 outwards moves to the end along smooth bore, thereby plug 12 and block up and leave the gap between 9, and pressure is low more, this gap is big more, thereby regulates flow automatically and keep the interior hydrodynamic pressure of container.
As shown in Figure 2, be applied to the embodiment in electric water heater field for the present invention, interlock valve (A among the figure) is connected in the water inlet of water-storage enclosed type electric water heater, the electric water heater water outlet is in parallel with a plurality of flowing water Valves, when any one or the several flowing water Valve opened wherein, the interlock valve is opened thereupon automatically, and when all outlet valves were all closed, then the interlock valve cut out, cuts off water inlet automatically.
Structure characteristic from the above description as seen, the present invention also can be applicable to the other field except that electric water heater, does not exceed protection scope of the present invention.
