The utility model discloses the advantage: the flow of two kinds of controllable differences is realized through detecting the internal temperature of admission valve to this product, and the inflow is little when having satisfied winter, and when summer the demand of inflow grow.
Description
Technical field
The utility model relates to a kind of magnetic valve, especially relates to a kind of magnetic valve for gas heater.
Background technology
Gas heater water inlet used is all common magnetic valve in the market, can only control a kind of flow. But along with the cold and hot variation of weather, water temperature is also changing thereupon, and in the time that water temperature is higher, same combustion gas is enough to heat water to very high, needs in this case a kind of summer and magnetic valve that winter, flow can be adjusted, in the time of winter, inflow is little, and the quantitative change of intaking in the time of summer is large.
Summary of the invention
The purpose of this utility model is the magnetic valve for gas heater that a kind of simple in structure, automatic water supplement is provided for prior art weak point.
The purpose of this utility model is to realize by following measures: a kind of magnetic valve for gas heater, includes valve body, includes valve casing, guide rod, piston and piston cap, spring, barrier film and the diaphragm plate of coil; Described barrier film, diaphragm plate overlay on the inner chamber valve seat of valve body, the axle center place of guide rod is provided with the inner chamber moving for piston, spring, piston and piston cap are positioned at the inner chamber of guide rod, the outer rim of guide rod is fixed on the inwall of valve casing, when valve casing is fixed on valve body, the edge mouth of guide rod bottom compresses barrier film, the axis of the axle center of piston and the axle center hole of diaphragm plate is overlapping, it is characterized in that, also has ring-type stripper loop, the first current-limiting apparatus, the second current-limiting apparatus, temperature sensor; The axis of the axle center hole of the axial line of described ring-type stripper loop and the axle center of piston, diaphragm plate is overlapping, the upper port of ring-type stripper loop is body cavity valve seat, the water chamber of valve body is divided into separately independently the first water chamber, the second water chamber by ring-type stripper loop, the first current-limiting apparatus, the second current-limiting apparatus are arranged on respectively the first water chamber, the second water chamber bottom, the outlet of the first current-limiting apparatus, the outlet of the second current-limiting apparatus are connected with valve body delivery port, and described temperature sensor is arranged on the chamber wall in valve inleting water chamber.
Compared with prior art, adopt a kind of magnetic valve for gas heater the utility model proposes, tool has the following advantages: this product enters the water temperature in valve body by detection, realize two kinds of controlled different flows, while having met winter, inflow is little, and the large demand of quantitative change of intaking in the time of summer.
Brief description of the drawings
Fig. 1 is the example structure schematic diagram the utility model proposes.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention is elaborated: Fig. 1 shows an embodiment of the present utility model. in figure, for a magnetic valve for gas heater, include: valve body 1, the valve casing 2 that includes coil 6, guide rod 7, piston 3 and piston cap 4, spring 5, barrier film 8 and diaphragm plate 9, ring-type stripper loop 11, the first current-limiting apparatus 103, the second current-limiting apparatus 104, temperature sensor 12, described barrier film 8, diaphragm plate 9 overlays on the inner chamber valve seat 10 of valve body 1, the axle center place of guide rod 7 is provided with the inner chamber moving for piston 3, spring 5, piston 3 and piston cap 4 are positioned at the inner chamber of guide rod 7, the outer rim of guide rod 7 is fixed on the inwall of valve casing 2, when valve casing 2 is fixed on valve body 1, the edge mouth of guide rod 7 bottoms compresses barrier film 8, the axis of the axle center hole of the axle center of piston 3 and diaphragm plate 9 is overlapping, the axis of the axle center hole of the axial line of described ring-type stripper loop 11 and diaphragm plate 9 is overlapping, the upper port of ring-type stripper loop 11 is valve body 1 inner chamber valve seat 10, the water chamber of valve body 1 is divided into separately independently the first water chamber by ring-type stripper loop 11, the second water chamber, the first current-limiting apparatus 103, the second current-limiting apparatus 104 is arranged on respectively the first water chamber, the second water chamber bottom, the outlet of the first current-limiting apparatus 103, the outlet of the second current-limiting apparatus 104 is connected with valve body 1 delivery port 102, described temperature sensor 12 is arranged on the chamber wall of valve body 1 intake antrum 101. the current-limiting apparatus using in this structure is known technology, can be commercial also can self manufacture, its principle is to make rubber parts be out of shape to change circulation passage by Water Pressure, in the time that hydraulic pressure diminishes, circulation passage becomes large, flow velocity is slack-off. hydraulic pressure becomes large circulation passage and diminishes, and flow velocity accelerates, thereby ensures to remain stable in different pressures down-off.
The utility model is like this work: the temperature detecting when temperature sensor is under set-point time, the coil no power of magnetic valve, piston is under the pressure of spring, piston cap compresses the aperture of diaphragm plate axle center hole, cut off the passage of valve inleting water chamber and the second water chamber, the water that valve inleting water chamber enters flows out from valve body the first water chamber. When the temperature that temperature sensor detects is sent the signal of telecommunication on set-point time, the coil of the magnetic valve generation magnetic force that powers on, overcoming spring force mentions piston to move up, piston cap separates with diaphragm plate axle center hole, open the passage of the second water chamber, the water that valve inleting water chamber is come together flows out valve body delivery port by the first water chamber, the second water chamber simultaneously.
The embodiment providing above does not form restriction of the present utility model, and in this area, those skilled in the art make within the scope of the appended claims various distortion or revise all in protection domain.
