Figure.
As shown in figure 1, pressure regulator includes：Housing 10 with air inlet 111 and exhaust outlet 112；It is arranged on housing
Nozzle 20 in 10；It is arranged on the barrier film 30 in housing 10；And advance in linkage (i.e. towards in Fig. 1 with the action of barrier film 30
Lower side shifting), retreat the valve element 40 opening 21 of nozzle 20 being opened, is closed (i.e. towards the upper side shifting in Fig. 1).
Also, the front of valve element 40 is provided with abutting part 41, valve element 40 follows barrier film 30 according to the pressure of primary side
Subtract the action that the change of the difference of the pressure of secondary side is carried out, and open the state (reference picture 2, Fig. 3) of opening 21 with by
Switch between the state (4~Fig. 7 of reference picture) that abutting part 41 closes opening 21 from primary side.
Also, abutting part 41 include inner circumferential side abutting part 411 and positioned at the inner circumferential side abutting part 411 radial outside it is outer
The week side of boss abutting part 412, in the state of the pressure of secondary side is for normal switching-off pressure, valve element 40 is retreated to first position (reference
Fig. 4, Fig. 5) so that inner circumferential side abutting part 411 is abutted with the peripheral part of opening 21 and closes opening 21, in the pressure of secondary side
It is that valve element 40 is further retreated relative to first position and reaches second in the state of the abnormal pressure more than normal switching-off pressure
Position (reference picture 6, Fig. 7), so that outer circumferential side abutting part 412 is abutted with the peripheral part of opening 21 and closes opening 21.
In the present embodiment, housing 10 includes main body 11 and installation lid 12 on the main body 11, in housing 11
Portion is formed with the second space S2 and make the first space that the first space S 1 connected with air inlet 111 connects with exhaust outlet 112
The connected entrance 114 that S1 and second space S2 is interconnected.Nozzle 20 is in substantially a ring-shaped, the complete cycle of its peripheral part and connected entrance 114
Abut, and the inner peripheral of opening 21 has elastic (herein, the outer surface of nozzle 20 is for example made up of elastomeric material).Valve element 40 with
Mobile mode passes through the opening 21 of nozzle 20, and with main part and annulus, wherein, main part is substantially in hemisphere
Shape, and constitute inner circumferential side abutting part 411 (the inner circumferential side abutting part have can be abutted with nozzle 20 cambered surface), annulus is from main body
The outer peripheral edge in portion protrudes towards the base end side of valve element 40, and (herein, valve element 40 is for example by resin to constitute outer circumferential side abutting part 412
Material is constituted).Herein, the bottom of main body 11 is provided with the lead column 113 coaxial with valve element 40, is set in the front end of valve element 40
There is recess 42, and the front end insertion recess 42 of lead column 113 is guided with the advance to valve element 40, retrogressing.
Also, in the present embodiment, barrier film 30 is arranged in second space S2, and second space S2 is divided into
Chamber and lower chambers, the pars intermedia of barrier film 30 are run through and are supported by valve element 40, and are supported with the bearing plate 611 for being installed on valve element 40
Connect, the bearing plate 611 along the vertical Directional Extension in the axial direction (above-below direction in Fig. 1) with valve element 40, bearing plate 611 with
The spring 70 exerted a force downward to bearing plate 611 is provided between lid 12, the coefficient of elasticity of the spring 70 is configured to
Valve element 40 is set to be in the position shown in Fig. 4, Fig. 5 in normal stopping fuel gas supply.
Additionally, when fuel gas supply is carried out, the pressure of secondary side declines because of the consumption of combustion gas, therefore, such as Fig. 2, Fig. 3 institute
Show, valve element 40 advances (i.e. towards the lower side shifting in Fig. 2, Fig. 3), be in abutting part 41 and separated with the inner peripheral 211 of opening 21
And the first state for opening opening 21.More specifically, when fuel gas supply is carried out, the pressure of secondary side is because of the consumption of combustion gas
And decline, therefore, the downward active force that bearing plate 611 is subject to by the grade of spring 70 is more than the pressing because of secondary side of bearing plate 611
Power etc. and the upward active force that is subject to, therefore, valve element 40 is moved downwardly together with bearing plate 611, drives the center of barrier film 30
Portion deforms to downside, and thereby, abutting part 41 is separated with opening 21 and forms gap between abutting part 41 and opening 21, and combustion gas can
Supplied to secondary side via the gap from primary side.
Additionally, in the state of the pressure of secondary side is for normal switching-off pressure (i.e. when fuel gas supply is normally stopped), such as
Shown in Fig. 4 and Fig. 5, valve element 40 retreats (i.e. towards the upper side shifting in Fig. 4, Fig. 5) to first position, makes inner circumferential side abutting part 411
Abutted with the inner peripheral 211 of opening 21 and close opening 21.On the other hand, the pressure in secondary side is more than normal switching-off pressure
In the state of the abnormal pressure of power (i.e. secondary side pressure anomaly rise when), as shown in Figure 6 and Figure 7, valve element 40 relative to
First position further retreats (i.e. towards the upper side shifting in Fig. 6, Fig. 7) and reaches the second place, makes at least outer circumferential side abutting part
412 abut by the part of radial outside with the ratio inner peripheral 211 of opening 21 and close (in the example shown in Fig. 6 and Fig. 7 opening 21
In son, not only outer circumferential side abutting part 412 is abutted with the ratio inner peripheral 211 of opening 21 by the position of radial outside, and inner circumferential side
Abutting part 411 is also abutted with the inner peripheral 211 of opening 21).
According to the pressure regulator of present embodiment, even if because certain reason is (such as in the edge of opening 21 of nozzle 20
There is foreign matter, the inner circumferential side abutting part 411 of valve element 40 cannot be abutted with the inner peripheral 211 of the opening 21 of nozzle 20) and cause two
The pressure anomaly of secondary side rises, and is retreated by valve element 40, and the outer circumferential side abutting part 412 of valve element 40 also can be with the opening 21 of nozzle 20
Ratio inner peripheral 211 by radial outside part abut and opening 21 is closed, accordingly, it is capable to using the periphery of the leading section of valve element 40
This simple structure of side abutting part 412 rises come the pressure anomaly for preventing secondary side.
Additionally, according to pressure regulator of the present utility model, a valve element 40 can be realized when fuel gas supply is stopped simultaneously
Closing to the opening 21 of nozzle 20 and to secondary pressure it is abnormal rise prevent, therefore, with set safety valve etc. other
The situation of the mechanism for preventing pressure from rising is compared, and can reduce number of parts, there is advantage in terms of cost.
Additionally, according to pressure regulator of the present utility model, when the pressure of secondary side recovers normal value, valve element 40 can be certainly
It is dynamic to return to normal condition (first position), therefore, and the mechanism that will be used for preventing pressure from rising is manually operated because of needs
The situation for returning to original state and setting hand reset mechanism is compared, energy reduces cost, also, common for preventing pressure
When malfunction occurs in the mechanism that power rises, gas supply business or commonly used person need to carry out recovery operation, and this can cause not
Combustion gas can be successfully supplied, and combustion gas then can be successfully supplied using pressure regulator of the present utility model.
The utility model is exemplarily described above in conjunction with accompanying drawing, it is clear that of the present utility model to implement not
Limited by above-mentioned implementation method.
