Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions
Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification
The Butut mode of attached drawing 1 is described, such as: the positional relationship of upper and lower, left and right is the Butut according to Figure of description 1
Direction determines.
The utility model is further described below with reference to examples and drawings:
As shown in Fig. 1, which includes tank body 1, waterproof baffle 2, input duct 6
With liquid outlet pipe 7；In the waterproof baffle 2 that 1 middle and lower part of tank body is fixed, tank body 1 is divided into the admission chamber 3 of left part by waterproof baffle 2
With the sap cavity 4 out of right part, there are overflow spacing in 2 upper end of waterproof baffle and tank body between 1 top；On the tank body 1 in 3 left side of admission chamber
Equipped with inlet, input duct 6 is fixedly installed on the left of tank body 1 at the inlet, is equipped on the tank body 1 on 4 right side of sap cavity out
Liquid outlet is fixedly installed with liquid outlet pipe 7 on the right side of tank body 1 at the liquid outlet；2 top of waterproof baffle is higher than inlet top and goes out
Liquid mouth top.In use, this auxiliary device is set loaded on upstream flow meter assembly (throttling set and differential pressure transmitter) with downstream
Between standby (including downstream line, downstream reservoir and down-stream system), fluid is successively flowed into through flowmeter assembly, this auxiliary device
In down-stream system；Wherein, fluid is entered by input duct 6 in the tank body 1 of this auxiliary device, due to herein from 6 mistake of input duct
It crosses to tank body 1, overcurrent cross-sectional area increases suddenly, the flows decrease of fluid, enters feed liquor after fluid impact waterproof baffle 2
In chamber 3, and in admission chamber 3 liquid level gradually rise, when liquid level is higher than input duct 6, entire input duct 6 can be made
And fluid is each filled in the throttling set of upstream, and form fluid-tight, to the property of fluid and the needs of state when meeting measurement, mention
High measurement accuracy, eliminate positive/negative-pressure connecting pipe fluid column potential difference influences caused by flow measurement；Simultaneously because fluid is kept off in water proof
It is flowing of turning back in front and back at plate 2, is equivalent to and plays the role of partition to continuous streaming flow；Therefore, even if down-stream system
There is fluctuation in fluid, will not influence the fluid in 2 left side admission chamber 3 of waterproof baffle, will not save to input duct 6 and upstream
Fluid in stream device causes fluctuation to interfere, and improves the smoothness of measurement.
Above-mentioned throttling set can be made further optimization and/or improvements with flowing full current stabilization auxiliary device according to actual needs:
As shown in attached drawing 1,2, waterproof baffle overflow hole 8 is distributed in the waterproof baffle 2 above inlet and liquid outlet；
8 bottom end of waterproof baffle overflow hole is higher than inlet top and liquid outlet top.Fluid passes through waterproof baffle overflow hole in admission chamber 3
8 overflows can eliminate the bubble in water when fluid is through waterproof baffle overflow hole 8 to sap cavity 4 out, further function as the work of current stabilization
With.
Blowdown operation is carried out for convenience of to tank body 1, as shown in attached drawing 1,2, sewage draining exit is equipped in the bottom of tank body 1, is arranging
It is fixedly installed with blow-off line 9 on dirty mouth, scum cock valve 10 is fixedly installed on blow-off line 9.
As shown in attached drawing 1,2, it is equipped with the overflow port that position is lower than inlet in 1 lower part of tank body in 3 left side of admission chamber, is being overflow
It is fixedly installed with overflow pipe 11 on head piece, relief cock valve 12 is fixedly installed on overflow pipe 11.Pass through overflow pipe
11 fluid situations when can check operation and water proof effect；It can also be used for blowdown, accelerate blowdown speed.
As needed, the front and back of tank body 1 is to cross-sectional area between 15 times to 20 times of 6 cross-sectional area of input duct.This
Sample makes fluid when entering in tank body 1, and flow velocity can rapidly slow down, and the fluid slowed down is directly entered in admission chamber 3, avoid
It is impacted in waterproof baffle 2 because flow velocity is too fast, reduces the influence to fluid flow in upstream throttle device.
As shown in attached drawing 1,2,6 left end of input duct is fixed with suction flange 13；7 left end of liquid outlet pipe is fixed with outlet method
Orchid 5.
The above technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and best implementation
