Abstract
The utility model discloses a water flow detector with an improved structure for a gas water heater. The water flow detector comprises a valve body, a water current rotor component, a Hall component, a piston and an elastic piece, wherein based on a using state, the water current rotor component is fixed in a cavity of the valve body; the Hall component is arranged on the outer side of the valve body and senses the water current rotor component; the side wall of the valve body extends to the outer side so as to form a hollow cylinder of which the outer end is enclosed; the hollow cylinder is communicated with a cavity on the inner side of the valve body; the piston is movably sealed in the hollow cylinder of the valve body; the piston can move in the hollow cylinder of the valve body along the axial direction of the hollow cylinder by a set distance; and one end of the elastic piece is pressed against the inner side wall of the end wall of the hollow cylinder, and the other end of the elastic piece is pressed against the end wall of one end of the piston. The cavity size of the valve body is increased by pushing the piston and compressing the elastic piece, so that damage to the water flow detector caused by icing and expansion of water is relived, the damage rate of the water flow detector caused by low air temperature is effectively lowered, and the water heater is further prevented from being damaged.
Description
Technical field
The utility model relates to a kind of discharge detector, relates in particular to a kind of structure improved gas heater discharge detector.
Background technology
Now owing to be subjected to the influence of environment, the various places climate change is bigger, cause some areas temperature very low, cause like this some areas owing to environment for use or in time the water in the emptying water heater conduit cause that water heater is freezing to leak, and cause the user further lost.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of structure improved gas heater discharge detector, this structure improved gas heater can be alleviated water freezing with the discharge detector and expand to the damage of discharge detector, thereby can reduce because the low situation that causes gas heater to damage of temperature.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of structure improved gas heater discharge detector, comprise valve body, current rotor assembly and Hall subassembly, to use state to be benchmark, the current rotor assembly is fixedly arranged in the cavity of valve body, Hall subassembly is located at the valve body outside and is responded to the current rotor assembly, described body wall extends to form the hollow cylinder of outer end sealing laterally, this hollow cylinder is connected with the inboard cavity of valve body, also be provided with piston and elastic component, the piston motive seal is located in the hollow cylinder of valve body, piston can be along its axially-movable setpoint distance in the hollow cylinder of valve body, elastic component one end only peaks at the end wall madial wall of hollow cylinder, the elastic component other end ends the end wall of top and piston one end, under the water heater normal condition, piston and elastic component are in free state, and when water heater is subjected to influencing of ambient temperature, cause icing expansion the in the water pipe owing to temperature is low, at this moment will impel piston to close elastic component one lateral movement, compression elastic piece, so just, increased the cavity volume of valve body, expand to the damage of discharge detector thereby alleviated water freezing, thereby reduced the situation that the damage that causes the discharge detector owing to temperature is low causes the water heater damage.
As further improvement of the utility model, described elastic component is a spring.
As further improvement of the utility model, the structure that described body wall extends to form the hollow cylinder of outer end sealing laterally is: body wall extends to form the hollow cylinder of an opening laterally, also be provided with an end cap, this end cap fixedly is covered on the hollow cylinder outer face of this opening, and this structure makes things convenient for the processing and manufacturing of valve body.
As further improvement of the utility model, piston can in the hollow cylinder of valve body the structure along its axially-movable setpoint distance be: the hollow cylinder of valve body is formed with radially inner contraction structure near valve body cavity one end, this radially inner contraction structure and hollow cylinder axial side wall form a loop step surface, the end wall backstop of the piston other end is in this circular step face, the piston other end is stopped by the ring-type stop surface, can not drop in the cavity of valve body.
As further improvement of the utility model, the inboard end wall of described elastic component one end and hollow cylinder is connected, and the end wall of the elastic component other end and piston one end is connected.
Useful technique effect of the present utility model is: the utility model is by setting up the hollow cylinder of the outer end sealing that is communicated with cavity in valve body, and in hollow cylinder, establish elastic component and piston, by promoting the cavity volume that the Piston Compression elastic component increases valve body, thereby having alleviated water freezing expands to the damage of discharge detector, effectively reduced because temperature hangs down the damage probability that causes the discharge detector, and then prevented the damage of water heater.
