Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
As shown in Figure 1 to Figure 2, a kind of pressure-maintaining valve for heater of the utility model description, including valve body 1, valve body 1 are set respectively
There are outlet 101 and entrance 102, is connected between outlet 101 and entrance 102 by movable chamber 103, wherein 103 inner wall of movable chamber
Equipped with diaphragm 2, for sealing or opening the communication port 8 between outlet 101 and movable chamber 103, diaphragm 2, which is connected with, adjusts gas bar 3,
It adjusts 3 one end of gas bar to extend at outlet 101, adjusts the tune being equipped at the elongated end of gas bar 3 for sealing or opening communication port 8
Gas head 301 adjusts gas bar 3 and is cased with spring 5, and 5 one end of spring peaks at 103 inner wall of movable chamber, and 5 other end of spring peaks at diaphragm 2.
This structure is applied in combination by adjusting gas bar 3, diaphragm 2, spring 5 and regulating the qi flowing in the channels head 301, can be stablized gas pressure, be avoided pressure inclined
The valve body of itself is impaired in ambassador's water heater.More specifically, under the pressure effect of combustion gas, push regulating the qi flowing in the channels head 301 mobile, combustion
Gap of the gas between regulating the qi flowing in the channels head 301 and communication port 8 enters, and is transported at water heater and burns.When the pressure of combustion gas is big,
Make 301 rapid displacement of regulating the qi flowing in the channels head, makes to seal diaphragm 2 at communication port 8 together with the displacement of gas bar 3 is adjusted, avoid the pressure mistake of combustion gas
Damage the valve body in water heater or even bad igniting greatly.
301 surface of regulating the qi flowing in the channels head described in the utility model is equipped with sealing cambered surface 304.The adjusting gas bar 3 is equipped with positioning plate
302, positioning plate 302 is tightly attached to 2 one side surface of diaphragm.The positioning plate 302 is connected with thread head 303, thread head 303 and diaphragm
2 are connected, and top plate 7 is connected to thread head 303, and top plate 7 is placed on another side surface of diaphragm 2.This structure passes through positioning plate 302
It is combined with top plate 7, diaphragm can be made to be connected to and adjust gas bar, made the mobile communication port of diaphragm, play promotion reliability.
The valve body 1, which is equipped with, adjusts head 4, and 5 one end of spring, which peaks at, to be adjusted at head 4, plays the elasticity and limitation of adjustment spring 5
Adjust 3 position of gas bar；The communication port 8 is equipped with sealing ring 6, further lift-off seal；When needing, sealing ring can be replaced
6；Sealing ring 6 is set to keep sealing effect for a long time.In addition, the regulating the qi flowing in the channels head 301 is greater than communication port 8, regulating the qi flowing in the channels head 301 is for the company of sealing
Port 8, the gap size between regulating the qi flowing in the channels head 301 and communication port 8 are conducive to regulating gas circulation, and regulating the qi flowing in the channels head 301 seals
Communication port 8 makes throttling action, plays the role of protecting water heater.
Upper is only the preferred embodiment of the utility model, is not intended to limit the utility model, all practical new at this
Made any modification, equivalent replacement or improvement etc., should be included in the protection of the utility model within the spirit and principle of type
