Specific embodiment
In order to be illustrated more clearly that the technical scheme of this utility model embodiment, below in conjunction with the accompanying drawings this utility model is entered
The explanation of one step, drawings in the following description are only some embodiments of the present utility model, for ordinary skill people
For member, on the premise of not paying creative work, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Embodiment one：
Refer to Fig. 1 to Fig. 3, a kind of improved automatic pressure regulator of the present utility model, including valve body 1, valve gap 2, valve element
3rd, voltage stabilizing diaphragm 4, elastic component 5, valve element 3 are movably arranged in valve body 1, and voltage stabilizing diaphragm 4 is in valve body 1 and border sealing is fixed
It is connected in valve body 1 and with valve element 3, elastic component 5 is located between voltage stabilizing diaphragm 4 and valve gap 2 and applies pretension to voltage stabilizing diaphragm 4
Power, valve body 1 are additionally provided with intake antrum 11 and water chamber 12, and intake antrum 11 is connected by valve port 13 with water chamber 12, and intake antrum 11 connects
Watering is connect, the connection water equipment 7 of water chamber 12, valve element 3 are actively located in valve port 13 and control the size of valve port 13, valve port 13
It is provided between valve element 3 for sealing the seal gasket 6 of close port 13, it is close by being provided with one between valve port 13 and valve element 3
Potting pad 6 so that when water route is static（When i.e. water equipment 7 quits work）, when intake pressure is increased to certain value, valve element
3 by 6 salable close port 13 of seal gasket, and so as to water under high pressure is isolated in intake antrum 11, and 12 static pressure of water chamber is tried hard to keep
Hold in relatively low water pressure condition, so as to protect the water equipment of pressure regulator valve rear end, this utility model simple structure, cost are relatively low,
Loss prevention function reliability.
In the present embodiment, seal gasket 6 is installed on the sealing face 33 that valve element 3 is engaged with valve port 13.Specifically, this reality
Apply in example, the conus portion 31 of the gap length being provided with the correspondence valve port 13 of valve element 3 between control valve element 3 and valve port 13, conus portion
Along the axially big toward the direction gradual change for opening valve port 13 of valve element 3, sealing face 33 is located at conus portion 31 on valve element 3 to 31 external diameter
Big external diameter side side wall on.
The seal gasket 6 of the present embodiment adopts laminated structure, for preferably fixing seal rubber cushion 6, prevents seal gasket 6
Deformation is produced when contradicting with valve port 13, the present embodiment is using radially-inwardly recessed on the side wall of the valve element 3 of 33 side of sealing face
One annular groove 32, seal gasket 6 are placed on annular groove 32 and are supported on sealing face 33, and simple structure, effect are more preferable.
As shown in figure 1, when water equipment 7 is in running order, the voltage stabilizing diaphragm 4 of automatic pressure regulator is in intake antrum 11
Upwardly-deformed or downward deformation under the dual function of hydraulic pressure and elastic component 5, voltage stabilizing diaphragm 4 is moved up and down with movable valve plug 3, so as to change
Become the gap length between conus portion 31 and valve port 3, and then the pressure value of adjustment water chamber 12, realize voltage stabilizing function.
As described in Figure 2, when water equipment 7 is in out-of-work state, and now, the hydraulic pressure of intake antrum 11 is low,
Voltage stabilizing diaphragm 4 moves down to open a certain size valve port 13, now, intake antrum in the presence of elastic component 5 with movable valve plug 3
11 are connected with water chamber 12, and the pressure of water chamber 12 is identical with intake antrum 11, but due to the hydraulic pressure of intake antrum 11 now it is low,
Therefore will not water equipment 7 be caused to damage.
As described in Figure 3, when water equipment 7 is in out-of-work state, and now, the hydraulic pressure of intake antrum 11 is high,
The band movable valve plug 3 in the presence of elastic component 5 of voltage stabilizing diaphragm 4 is moved up until close port 13, now, in seal gasket 6
Under sealing function, intake antrum 11 is completely isolated with water chamber 12, and water chamber 12 is not affected to keep by the hydraulic pressure of intake antrum 11
Relatively low hydraulic pressure, so as to cause to damage to water equipment 7.
Certainly, it is readily apparent that, seal gasket 6 can also select to be installed in the sealing that valve port 13 is engaged with valve element 3 and match somebody with somebody
On conjunction face, equally also sealing function can be played to valve port 13.For the preferably fixing seal rubber cushion 6 at the valve port 13, fluid sealant
Pad 6 may be selected the fixed lid by with 13 affixed cooperation of valve port（It is not shown）It is pressed at the sealing mating surface of valve port 13, ties
Structure is simple, fixed.
Embodiment two：
The present embodiment is roughly the same with the structure and principle of embodiment one, differs only in：The seal gasket 6 of the present embodiment
Do not adopt laminated structure, and adopt section for U-shaped structure, and valve element 3 is radially outward convexly equipped with a ring seal platform 34, only
The water surface 33 is formed on ring seal platform 34, and seal gasket 6 is placed on ring seal platform 34 by the U-lag on seal gasket 6,
The seal gasket 6 of setting U-shaped structure is advantageous in that and the seal gasket 6 of one laminated structure of embodiment can be avoided higher in hydraulic pressure
In the case of, when seal gasket 6 is near valve port, High-Pressure Water can impact seal gasket 6 so that the periphery of seal gasket 6 can be somewhat
Tilt a bit, so as to the problem for causing noise occur.Additionally, for preferably fixing seal rubber cushion 6,34 both sides of ring seal platform
Valve element 3 on be also radially-inwardly arranged with annular groove 32, embedded two annular grooves 32 in two ends of the U-shaped structure of seal gasket 6
Interior, fixation is more firm.
Other not described structures of the present embodiment and principle are consistent with embodiment one, repeat no more here.
Although specifically showing and describing this utility model with reference to preferred embodiment, those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
On this utility model is made a variety of changes, be protection domain of the present utility model.
