The barrier film 5 being made up of flexible material, its junction for being located at control air flue 2 and fluid passage 3 simultaneously will control air flue 2
Separate with fluid passage 3；When the pressure for controlling the pressure in air flue 2 to be more than in fluid passage 3, barrier film 5 can deform and close stream
Body passage 3, when the pressure for controlling the pressure in air flue 2 to be less than in fluid passage 3, barrier film 5 can deform and leave fluid passage 3.
There is fluid passage 3, fluid passage 3 is the passage for being flowed through for fluid, and it two in the diaphragm valve of the present embodiment
End can be connected with pipeline etc. respectively；Control air flue 2, the connection low pressure of low pressure port 21 of the control air flue 2 are additionally provided with diaphragm valve
End (such as negative pressure), and high-pressure mouth 22 then connects hyperbar end (such as malleation).
As shown in figure 1, when negative pressure is accessed by low pressure port 21 in controlling air flue 2, pressure ratio fluid passage 3 therein
Pressure is low, therefore the stress of barrier film 5 of flexible material (such as rubber) deforms and concaves towards inside control air flue 2, so as to allow stream
Body flows through from fluid passage 3, diaphragm valve conducting.As shown in Fig. 2 when malleation is accessed by high-pressure mouth 22 in controlling air flue 2,
The pressure of pressure ratio fluid passage 3 therein is big, and the stress of barrier film 5 of flexible material deforms and is convex to inside fluid passage 3,
Wall with fluid passage 3 is contacted, so that closed fluid passages 3, fluid cannot flow through, barrier film valve breakdown.
As can be seen here, the diaphragm valve of the present embodiment is realized controlling completely by air pressure, therefore need not set spring, pull bar
Deng its simple structure, low cost, fault rate is greatly reduced.
Preferably, diaphragm valve also includes the control device 4 that can switch between conducting state and off state, control device 4
The connection between fluid passage 3 and hyperbar end can be cut off in conducting state (so as to allow fluid passage 3 to connect with low pressure end
Connect), the connection between fluid passage 3 and low pressure end can be cut off in off state (so as to allow fluid passage 3 and hyperbar end
Connection).
To realize the control to pressure in control air flue 2, control device 4 can be also set in diaphragm valve, the control device 4
Control air flue 2 (specifically controlling the low pressure port 21 and high-pressure mouth 22 of air flue 2) is located at and low pressure end, hyperbar end between, is led to
The switching of its state is crossed, control air flue 2 can be made to be turned on low pressure end or hyperbar end, so that with different pressure.
It is furthermore preferred that control device 4 includes：It is connected to the first passage 41 between low pressure end and low pressure port 21；It is connected to
Second channel 42 between hyperbar end and high-pressure mouth 22；It is connected to the slideway 49 between first passage 41 and second channel 42, slideway
Sliding block 48 is provided with 49；Driver (not shown), for driving sliding block 48 to move to block first passage in slideway 49
41 or second channel 42.
It is further preferred that control device 4 is magnetic valve；Driver is magnet coil.
As shown in Figure 1 and Figure 2, the passage (control being connected with low pressure end and hyperbar end respectively is may include in control device 4
Device processed 4 can be also connected by other pipelines with low pressure port 21, high-pressure mouth 22 again), and it is provided with slideway between the two passages
49, sliding block 48 in slideway 49, so as to when sliding block 48 is slided in slideway 49, in two passages be blocked, and then
The connection between corresponding air pressure end and control air flue 2 is cut off, and only allows another air pressure end to be turned on control air flue 2.
Specifically, above control device 4 can be magnetic valve, you can drive the movement of the sliding block 48 by magnet coil.
Preferably, the valve body 1 of diaphragm valve includes the upper valve body 11 and the lower valve body 12 that are detachably connected；Control air flue 2 is located at
In upper valve body 11；Fluid passage 3 is in lower valve body 12.
As shown in Figure 1 and Figure 2, from from the point of view of being easy to process, repair, valve body 1 is not a part for entirety, and
It is to be combined by upper valve body 11 and lower valve body 12.Control air flue 2 and fluid passage 3 are respectively arranged on upper valve body 11 and lower valve above
In body 12, air flue 2 is controlled to be connected naturally with fluid passage 3 so when upper valve body 11 and lower valve body 12 are linked together, and
Barrier film 5 can located at (be actually attached on one of them certainly) between upper valve body 11 and lower valve body 12 with will control air flue 2 with
Fluid passage 3 separates.
It is furthermore preferred that being detachably connected by screw 9 between upper valve body 11 and lower valve body 12.
Specifically, upper valve body 11 can be linked together with lower valve body 12 by screw 9, such Detachable connection structure letter
It is single, convenient disassembly.
Preferably, the position of correspondence barrier film 5 is provided with raised 31 in fluid passage 3, when the pressure in control air flue 2 is more than stream
Barrier film 5 can deform and be contacted with closed fluid passages 3 with raised 31 during pressure in body passage 3.
Because the deformation extent of barrier film 5 is limited, therefore in order to reach the purpose of more preferable closed fluid passages 3, can be such as Fig. 2 institutes
Show, the position of correspondence barrier film 5 sets raised 31 in fluid passage 3, as long as so that barrier film 5 occurs lesser degree of deformation
Contacted with raised 31, closed fluid passages 3.
Preferably, control air flue 2 is connected with fluid passage 3 respectively in multiple positions, and each junction is respectively provided with one respectively
Individual barrier film 5.It is furthermore preferred that control air flue 2 correspondence low pressure port 21 and high-pressure mouth 22 two positions respectively with the phase of fluid passage 3
Even, two junctions are respectively provided with a barrier film 5 respectively.
That is, control air flue 2 can be connected in multiple positions with fluid passage 3, each junction is designed with accordingly
Barrier film 5, so that each barrier film 5 can closed fluid passages 3.So, if there is bad sealing of the indivedual barrier films 5 to fluid passage 3
Close, then diaphragm valve can still realize good shut-off effect on the whole.More specifically, as shown in Figure 1 and Figure 2 air flue 2 can be controlled to exist
Corresponding to the position of low pressure port 21 and high-pressure mouth 22 respectively, be connected with fluid passage 3 (also will be by leading between certain two junctions
It is logical), such design structure is the easiest.
It is understood that embodiment of above be merely to illustrate that principle of the present utility model and use it is exemplary
Implementation method, but the utility model is not limited thereto.For those skilled in the art, this is not being departed from
In the case of the spirit and essence of utility model, various changes and modifications can be made therein, and these variations and modifications are also considered as this reality
With new protection domain.
