Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model first embodiment.
Fig. 2 is the structural representation of the utility model second embodiment.
Fig. 3 is the structural representation of built-in hydraulically-controlled one-way valve in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 and Fig. 2 illustrates embodiment of the present utility model, the flow control apparatus for water of described Teat pump boiler, and it has the water heater body 1 of heating water tank, water heater body 1 is equipped with water pipeline 2.Built-in hydraulically-controlled one-way valve 3 is embedded with in described water pipeline 2.Stability Analysis of Structures, prevent the water backflow of heating, protection heating water tank, ensures the normal use of the heating water tank of Teat pump boiler.Wherein, described water pipeline 2 comprises cold water inlet road 21 and hot water effluent's pipeline 22.Cold water inlet road 21 adaptation is installed on the cooling water inlet 11 of water heater body 1; Hot water effluent's pipeline 22 adaptation is installed on the hot water outlet 12 of water heater body 1.Built-in hydraulically-controlled one-way valve 3 adaptation is flush-mounted in cold water inlet road 21 or hot water effluent's pipeline 22 inner chamber.In practical operation, built-in hydraulically-controlled one-way valve 3 adaptation is flush-mounted in the water outlet end inner chamber on cold water inlet road 21, as shown in Figure 1; Or built-in hydraulically-controlled one-way valve 3 adaptation is flush-mounted in the water inlet end inner chamber of hot water effluent's pipeline 22, as shown in Figure 2.Replace external one-way valve, Stability Analysis of Structures, does not limit by installation site, not by F. O. D, effectively extends the service life of built-in hydraulically-controlled one-way valve 3.
With reference to shown in Fig. 3, in prioritization scheme, the valve seat 31 that described built-in hydraulically-controlled one-way valve 3 comprises band tapered channel 32 and the valve core spheroid 33, the spring 34 that are installed in valve seat 31, top, spring 34 one end press against valve seat 31 inwall, spring 34 other end is connected with valve core spheroid 33, and valve core spheroid 33 is in the arrival end of tapered channel 32.That is, current are along cold water inlet road 21 through valve seat 31, then enter the tapered channel 32 in valve seat 31, when water pressure is enough high, valve core spheroid 33 thrown off tapered channel 32, make current pass tapered channel 32 and flow into heating water tank.When total water source that cold water inlet road 21 is anhydrous, be connected with cold water inlet road 21 cuts off the water, in these situations such as to cut off the water supply in heating water tank; spring 34 has sufficient force to block on tapered channel 32 by valve core spheroid 33; Stability Analysis of Structures; prevent the water backflow of heating; protection heating water tank, ensures the normal use of the heating water tank of Teat pump boiler.And described valve seat 31 is flush-mounted in the water outlet end inner chamber on cold water inlet road 21; Or valve seat 31 is flush-mounted in the water inlet end inner chamber of hot water effluent's pipeline 22.Do not limit by installation site, easy for installation, and replace external one-way valve, not by F. O. D, effectively extend the service life of built-in hydraulically-controlled one-way valve 3.
Comprehensively above-mentioned, by being embedded with built-in hydraulically-controlled one-way valve 3 in water pipeline 2, effectively eliminate following phenomenon: (1), cut off the water when heating water tank water inlet end, delivery port is closed, Action of Gravity Field due to water causes the aqueous reflux in heating water tank, causes heating water tank negative pressure, damages heating water tank; (2), heating water tank and there is certain difference in height with water spot, and heating water tank is aloft, when water inlet pipe is cut off the water, opens and flows out with the water of inner bag during water spot, heating water tank namely can be caused to produce the situation of negative pressure, damage heating water tank; (3), water tank and there is certain difference in height with water spot, aloft, water inlet pipe hydraulic pressure too low (flow velocity of water is excessively slow), opens with going out water speed during water spot much larger than water intake velocity heating water tank, heating water tank can be caused equally to produce the situation of negative pressure, damage heating water tank.Therefore, the normal use of the flow control apparatus for water energy effective guarantee heating water tank of this structure.
Above-mentioned specific embodiment is only the good detailed description of the invention of the utility model effect, and the flow control apparatus for water of all Teat pump boilers identical or equivalent with this structure, all in the protection domain of the application.
