Description
Technical field
The present invention relates to a kind of built-in type constant pressure reagent barrel, especially it is a kind of it is simple and reliable for structure, save space and
It is easy to arrange, can guarantee that the reagent constant pressure of injection and the built-in type constant pressure reagent barrel of constant flow.
Background technology
At present, water quality online analyzer reagent adding part using peristaltic pump or precision metering pump reagent from being placed in ground
To being above pumped into instrument reaction tank in big reagent barrel, connecting line is complicated, trouble point not easy care more, peristaltic pump and precision
Measuring pump cost is high and easily blocks, and brings very burden to attendant, reagent barrel ground near instrument is put in addition
Space-consuming is put, operating personnel is influenceed and on-site maintenance is worked.
The content of the invention
In order to overcome, existing reagent adding part-structure is complicated, cost is high, space-consuming is big, easy care does not lack more for trouble point
Point, the purpose of this utility model are to provide a kind of simple and reliable for structure, saving space and are easy to arrange, can guarantee that the examination of injection
The built-in type constant pressure reagent barrel of agent constant pressure and constant flow.
Built-in type constant pressure reagent barrel in the utility model includes reagent barrel device body, reagent barrel appliance cover,
Both fasten by threaded connection.Angrily pressure chamber peace weighing apparatus pipe, the reagent barrel appliance cover are provided with inside the reagent barrel appliance cover
10 millimeters of internal balance pipe distance reagent barrel inside bottom, the balance pipe inside communicate with air, the reagent barreled
Put body bottom portion and be respectively arranged on the left side and the right side left lead and right lead, outside the left and right lead of reagent barrel bottom of device
Footpath is identical, and the left lead endoporus is connected to the inlet of two three-way electromagnetic valves by adapter, and two three-way electromagnetic valve goes out
Liquid mouth is connected with out liquid flexible pipe by flared fitting, it is described go out liquid flexible pipe be provided with flow control valve, the right lead
Provided with blind screw hole, banking stop is screwed in the blind screw hole with screw, and the banking stop can limit reagent barrel
Body upset is fallen.Before the reagent barrel device body bottom front guide post insertion instrument housing in guide groove, it is oriented to after described
After post insertion instrument housing in guide groove.Reagent barrel during reagent adding is needed outwards to be slided inside instrument housing
It is dynamic, expose reagent bung in order to reagent adding.
It is as follows that the constant pressure type goes out liquid principle：When two three-way electromagnetic valve is opened, in the reagent barrel device body
Reagent because Action of Gravity Field declines from high level to low liquid level, through it is described go out liquid flexible pipe be injected into instrument reaction tank, elapsed time t
Afterwards, the air pressure of the angrily pressure chamber drops to Pt from 1 atmospheric pressure P0 and forms negative pressure, under the reagent liquid level in the balance pipe
Drop, when this process proceeds to pressure-equalizing pipe lower end outlet A points, now pressure is equal to an atmospheric pressure at pipe inner outlet
P0, and equal to outer pressure Pt+htd (d is the proportion of reagent) is managed, when reagent continues injection, Pt+htd is slightly less than P0, empty
Gas via the pressure-equalizing pipe lower end outlet A place enter reagent in, finally float add in negative pressure room, when described two lead to
During closed electromagnetic valve, recover pressure balance, i.e. Pt+htd=P0.Reagent injection process is a continuous process of repetition, examination
Agent injection rate very little, cause the reduction very little of liquid level, every time during breakdown pressure is equilibrated to and restored balance, pressure at A points
Very little is fluctuated, substantially remains in P0, due to pressure chamber section very little of doing something in a fit of pique, and originates liquid level close to closure lower surface, it is easy to
Above-mentioned balance is established on several reagents injection cycle.After establishing pressure balance, liquid outlet quantity only and two three-way electromagnetic valves unlatching when
Between it is linear.
The beneficial effects of the utility model are：Reagent barrel uses constant pressure type principle, saves reagent；Reagent barrel knot
Structure is simple and reliable, and compact is easy to arrange in instrument housing.

Embodiment
The specific embodiment of the utility model is described further below in conjunction with accompanying drawing.As shown in drawings, reagent
The top left side of barrel body 1 is provided with and is connected with externally threaded bung 2 with the internal thread of reagent barrel appliance cover 3 and leans on sealing gasket 4
Hermetic seal effect is played, be formed with pagoda joint 5 inside reagent barrel appliance cover 2 is connected with the interference of balance pipe 6, reagent barrel appliance cover 2
Top is provided with balance pipe 7 with being connected inside balance pipe 6, and the cavity inside reagent bung forms pressure chamber 23 of doing something in a fit of pique.Reagent barreled
Put the forward and backward side in the bottom of body 1 and be respectively equipped with front guide post 8 and rear lead 9.The bottom of front guide post 8 is formed with internal thread and reagent
Connected inside barrel, rear lead 9 is provided with blind screw hole, and screw 10 fastens banking stop 11 on rear lead 9.Adapter
12 tops are connected with the bottom internal thread of front guide post 8, and the bottom of adapter 12 is threadedly coupled with the inlet 14 of two three-way electromagnetic valve 13, and two
The liquid outlet 15 of three-way electromagnetic valve 13 is threaded with flared fitting 16, and the afterbody of flared fitting 16 is cased with out liquid flexible pipe 17, nut
18 internal threads are connected fastening with the middle part external screw thread of flared fitting 16 and compress out liquid flexible pipe 17.Go out liquid flexible pipe 17 and be cased with flow above
Adjusting switch 19.Before the bottom front guide post 8 of reagent barrel device body 1 insertion instrument housing 20 in guide groove 21, rear lead 9 is inserted
Enter after instrument housing 20 in guide groove 22, it is necessary to need to only be pulled outwardly reagent barrel device body 1 during reagent adding, rear lead 9 reaches
It is spacing by fore-and-aft direction at the front end semicircle of guide groove 21 afterwards.Banking stop 11 limits the upset of reagent barrel device body 1 simultaneously
Motion, now open lid 2 on reagent barrel and reagent is added into reagent barrel, then cover reagent barrel appliance cover 2 and revolve
Tightly.Reagent barrel device body 1 is pushed in instrument housing 20, front guide post 8 tries when propping up preceding guide groove 21 most at the semicircle of inner side
Agent barrel body 1 arrived its placement precalculated position.
