Description
Technical field
The present invention is a kind of gas heater, particularly a kind ofly can keep the constant water way stable flow type gas burning water heater of water temperature.
Background technology
Existing gas heater, its leaving water temperature are subjected to influence that admission pressure, intake pressure change greatly, occur sometimes hot and sometimes cold phenomenon in the use easily.Be the variation of avoiding coming because of the fluctuation feedwater temperate zone of admission pressure and intake pressure, the medium-to-high grade gas heater of existing market top brand has increased the metastable gas pressure device, this metastable gas pressure device can be guaranteed the stable of admission pressure, but can not eliminate the fluctuation of hydraulic pressure, so when hydraulic pressure was unstable, its leaving water temperature still changed easily.
Below by the introduction to several concrete technical schemes, understand prior art has which shortage actually:
List of references CN2628940Y discloses a kind of water inlet constant-current stabilizer of domestic gas-fired water heater, and this device comprises: water inlet valve body, spring base, big spring, water flowing cover, end cap, limited block, little spring, spool, cushion block, regulating block, jump ring, latch and push rod are formed.This device reaches the purpose of regime flow according to the size in the slit of the variation automatic regulating valve core of extraneous hydraulic pressure and valve base chamber.The weak point of the technical program is that other parts are too many, causes cost height, difficult, the use inconvenience of maintenance.
List of references CN1319750A discloses a kind of directly-heated type gas heater constant temperature system, all be provided with flow control valve on the bypass cold water channel that this system is mixed with main channel hot water in the main channel, the blast tube, and be provided with temperature sensor at mixed water place, the flow of the Signal Regulation water by this temperature sensor, thus realize making water heater to keep constant temperature.Though the constant-current stabilizer of the technical program is to rely on the mechanical performance of assembly to realize flow-control, it is a flow of regulating water indirectly by the signal of temperature sensor, so just be short of to some extent in sensitivity.
List of references CN2327956Y discloses a kind of gas heater automatic voltage regulator, this device comprises: booster pump, inlet and outlet pipe lines connect the deposit water suction head that is connected with buffer tank, are with that hydraulic pressure touches the hydraulic control valve of motor start switch, the water-electricity linkage switch that is connected with the pressure charging valve water inlet, the hydraulic pressure automatic regulator of the outlet conduit connection that is connected with the booster pump water sucting cavity on the inlet channel that the booster pump water sucting cavity connects.The flow-control of the technical program realizes by circuit, booster pump, motor, hydraulic control valve, pressure charging valve, water-electricity linkage switch, hydraulic pressure automatic regulator etc. are arranged in the circuit, parts are too many in addition, and complex structure causes cost height, difficult, the use inconvenience of maintenance.
Summary of the invention
The objective of the invention is to invent a kind of flow of inlet water that makes and keep constant substantially, thereby realize the water way stable flow type gas burning water heater that leaving water temperature remains unchanged substantially at the deficiencies in the prior art.
The present invention realizes as follows:
The present invention is provided with a constant-current stabilizer on the water inlet road of gas heater, described constant-current stabilizer comprises current stabilization lid, current stabilization core and O shape rubber ring, and the current stabilization lid is a cylindrical shell, and an end of cylindrical shell is an inlet opening; The bottom of current stabilization core is provided with a circle plum blossom tooth, and the periphery of plum blossom tooth is installed with frame, forms some through holes between plum blossom tooth and frame; O shape rubber ring is set on the current stabilization core, and the current stabilization core is installed in the current stabilization lid by frame, and O shape rubber ring is enclosed between current stabilization core and the current stabilization lid.
O shape rubber ring is in the state of matched in clearance between current stabilization core and current stabilization lid.
The other end of current stabilization lid is provided with a cannelure that expands outwardly, and the frame of current stabilization core connects airtight in this cannelure, and this structure is convenient to the location of current stabilization core.
Operation principle of the present invention is: the current stabilization core itself has many through holes, during water heater working, cold water flows into from through hole, flow to water heater from the inlet opening, in the process that current enter, current are located at O shape rubber ring between current stabilization core and the current stabilization lid with compressing, and make its distortion, utilize the deformation of O shape rubber ring just, change the size of the water-flowing path between O shape rubber ring and described some through holes, make its stable function thereby realize regulating discharge.Make it stable owing to regulate discharge, also just guaranteed the stable of water temperature.
