Description
Technical field
The utility model relates to water treatment procedure pressure-measuring instrument instrument field more particularly to a kind of measurement negative pressure instrument
Protective device.
Background technique
The effect of negative pressure instrument is the negative pressure force value in jet process in real-time measurement feedback channel.Existing technology
In, instrument is typically directly connected to fluidic device, this technical solution in actual use, since the negative pressure in pipeline is a certain
Moment instantaneously increases, and the diaphragm in material powders easily disruptive pressure table that pressure drives destroys table body, it is therefore desirable to design one
Kind protective device preferably solves this problem using the design feature of its own.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and it is negative to provide a kind of measurement
Instrument protection device is pressed, normal work of the protective meter in jet process when so that pressure is excessive in pipeline, plays drainage
The effect of gas pressure release.
The utility model is to be achieved by the following technical programs:
A kind of measurement negative pressure instrument protective device, including a cushion chamber, cushion chamber external form is horizontal capsule shape, internal
Hollow, top is equipped with metering device, is connected between cushion chamber upper surface and metering device lower surface by the perforation of connecting tube mechanism,
It is interconnected in cushion chamber in metering device, cushion chamber right side is connected with solenoid valve, and the solenoid valve other end connects discharge pipe
Road, perforation is connected with conduction pipe behind cushion chamber, and the conduction pipe other end is equipped with flange, and flange quadrangle is equipped with fillister head screw.
According to the above technical scheme, it is preferable that connecting tube mechanism is that multiple connection short tubes are constituted, between each connection short tube
Pass through welding union connection.
According to the above technical scheme, it is preferable that metering device is rounded cylindrical, and two sides are equipped with the capping of central, clear,
One side capping is internal to be equipped with dial plate.
The beneficial effects of the utility model are: being made by increasing buffer unit between the instrument and pipeline of negative pressure instrument
It obtains material powders and is not easy to puncture the diaphragm destruction table body in table；And solenoid valve and discharge line are increased, the two plays pressure release
Effect, when pressure is excessive in jet process, can in time by inside pipeline gas and liquid be discharged, protect instrument not to be damaged
Evil.
Detailed description of the invention
Fig. 1 shows the schematic perspective view of embodiment according to the present utility model.
In figure: 1. metering devices, 2. cappings, 3. connecting tube mechanisms, 4. welding unions, 5. cushion chambers, 6. socket cap spiral shells
Nail, 7. conduction pipes, 8. flanges, 9. solenoid valves, 10. discharge lines.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, with reference to the accompanying drawing
The utility model is described in further detail with most preferred embodiment.
As shown, the utility model provides a kind of measurement negative pressure instrument protective device, including a cushion chamber 5, delay
Rushing 5 external form of chamber is horizontal capsule shape, inner hollow, and top is equipped with metering device 1, under 5 upper surface of cushion chamber and metering device 1
By the perforation connection of connecting tube mechanism 3 between surface, cushion chamber 5 is interior to be interconnected in metering device 1,5 right side of cushion chamber
It is connected with solenoid valve 9,9 other end of solenoid valve connects discharge line 10, and perforation is connected with conduction pipe 7, conduction pipe behind cushion chamber 5
7 other ends are equipped with flange 8, and 8 four jiaos of flange are equipped with fillister head screw 6.
According to above-described embodiment, it is preferable that connecting tube mechanism 3 is that multiple connection short tubes are constituted, between each connection short tube
It is connected by welding union 4.
According to above-described embodiment, it is preferable that metering device 1 is rounded cylindrical, and two sides are equipped with the capping 2 of central, clear,
One side capping is internal to be equipped with dial plate.
In the technical scheme, it is equipped with pressure transmitter inside metering device 1, electric signal can be converted by pressure signal
Output, and pressure data is shown on dial plate, in working condition, conduction pipe 7 is connect by flange 8 with water sprayer, in pipeline
When internal pressure moment increases, the material powders that pressure drives can enter in cushion chamber, can be with when internal pipe pressure is excessive
Solenoid valve 9 is opened, by inside cushion chamber 5 and pipeline gas and liquid by 10 mouthfuls of discharge line be discharged.
According to above-described embodiment, the utility model by increasing buffer unit between the instrument and pipeline of negative pressure instrument,
So that material powders are not easy to puncture the diaphragm destruction table body in table；And solenoid valve and discharge line are increased, the two, which plays, lets out
Pressure effect, when pressure is excessive in jet process, can in time by inside pipeline gas and liquid be discharged, protect instrument not by
Damage.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
