Existing diaphragm valve generally only controls the function of flow, and the working condition of its flow is all judged by artificial observation, when need
When diaphragm valve is embedded in into underground, it will be unable to know the working condition of diaphragm valve.
Utility model content
In view of this, the utility model, which provides, conceives a kind of different diaphragm valves, solves diaphragm valve in the prior art
When applying to ground end can not detection flows working condition technical problem.
The technological means that the utility model uses is as follows：A kind of diaphragm valve, including bonnet and valve body, the bonnet and valve body
It is fixedly connected, barrier film film is installed between the bonnet and valve body, spring is installed in the bonnet, the barrier film film is in
Spheric, the barrier film film are provided with spring washer, and the spring lower section connects the barrier film film, institute by spring washer
State valve body and be provided with water inlet and delivery port, the water inlet, which goes out, is provided with pressure sensor, and the delivery port goes out to be provided with flow
Sensor.
Preferably, the junction of the bonnet and valve body and the barrier film film is equipped with recess, the barrier film film with
Bonnet and the valve body junction is provided with convex portion, and the recess matches with the convex portion.
Preferably, the water inlet includes upstream water inlet and downstream water inlet.
Preferably, the bonnet is provided with uuper valve chamber water inlet.
Using a kind of diaphragm valve provided by the utility model, pressure sensor is used for monitoring the hydraulic pressure in conduit,
Flow sensor is used for monitoring the water-carrying capacity in pipeline, when diaphragm valve is embedded in underground, is passed by pressure sensor and flow
Sensor can monitor hydraulic pressure and water-carrying capacity in valve body at any time, and by the hydraulic pressure and flow information monitored, in time analysis
The working condition of underground piping system, make the adjustment of adaptability in time according to working condition, solve existing apply on ground
Beneath diaphragm valve can not know the problem of its specific works state.
Brief description of the drawings
Fig. 1 is a kind of schematic cross-section of diaphragm valve provided by the utility model；
Fig. 2 is a kind of structural representation of diaphragm valve provided by the utility model.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Figure 1 to Figure 2, a kind of diaphragm valve, including bonnet 1 and valve body 2, the bonnet 1 are fixedly connected with valve body 2,
Barrier film film 3 is installed between the bonnet 1 and valve body 2, can use here bolt through bonnet 1 and barrier film film 3 with it is right
The screwed hole on valve body 2 answered is fixed, and spring 4 is provided with the bonnet 1, the 3 spherical shape of barrier film film, institute
State barrier film film 3 and be provided with spring washer 5, the lower section of spring 4 connects the barrier film film 3, the valve by spring washer 5
Body 2 is provided with water inlet 6 and delivery port 7, and the water inlet 6 goes out to be provided with pressure sensor 8, and the delivery port 7, which goes out, is provided with stream
Quantity sensor 9.Lower pressing spring 4 can block barrier film film 3 water inlet of valve body 2；Conversely, the return of spring 4, water can be from valve body 2
Water inlet 6 flow into and flowed out from delivery port 7.Pressure sensor 8 is used for monitoring the hydraulic pressure in the pipeline of valve body 2, flow sensor 9
, can be with by pressure sensor 8 and flow sensor 9 when diaphragm valve is embedded in underground for monitoring the water-carrying capacity in pipeline
The hydraulic pressure and water-carrying capacity in valve body 2 are monitored at any time, and by the hydraulic pressure and flow information monitored, analyze underground piping in time
The working condition of system, the adjustment of adaptability is made in time according to working condition, solve it is existing apply underground every
Film valve can not know the problem of its specific works state.
In one embodiment, the junction of the bonnet 1 and valve body 2 and the barrier film film 3 is equipped with recess 10, institute
State barrier film film 3 and be provided with convex portion 11 with the bonnet 1 and the junction of valve body 2, the recess 10 matches with the convex portion 11.
When spring 4 presses down, do not loosened tightly in order to avoid barrier film film 3 blocks, can be by the barrier film film 3 and the bonnet
1 and the junction of valve body 2 be set as convex portion 11, convex portion is stuck in the recess 10 of bonnet 1 and valve body 2, when spring 4 is pressed downward, convex portion 11
It is stuck in recess 10 so that the fixed position of barrier film film 3 is not influenceed by elastic force, ensures diaphragm valve sealing and stability.
In one embodiment, the water inlet 6 includes upstream water inlet 61 and downstream water inlet 62.Multiple water inlets are set
Mouthfuls 6 control the size of inflow, and the bonnet 1 is provided with uuper valve chamber water inlet 12.By water under high pressure from uuper valve chamber water inlet
12 enter in bonnet 1, barrier film film 3 are pressed down, you can with hydraulic pressure come application valve body on and off.
In summary, using a kind of diaphragm valve of the present utility model, pressure sensor 8 is used for monitoring in the pipeline of valve body 2
Hydraulic pressure, flow sensor 9 are used for monitoring the water-carrying capacity in pipeline, when diaphragm valve is embedded in underground, pass through the He of pressure sensor 8
Flow sensor 9 can monitor hydraulic pressure and water-carrying capacity in valve body 2 at any time, and by the hydraulic pressure and flow information monitored,
The working condition of analysis underground piping system in time, the adjustment of adaptability is made according to working condition, is solved existing in time
The problem of applying the diaphragm valve in underground can not know its specific works state.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc., the utility model should be included in
Within the scope of protection.
