Abstract
It the utility model is related to a kind of open blowdown on-line period device, including Drainage pipe and it is arranged on the sampling valve being connected outside Drainage pipe and with Drainage pipe, Drainage pipe at the valve port of the sampling valve is internally provided with curved baffle, curved baffle opening upwards, and sampling cavity is formed between the inwall of Drainage pipe, the valve port of sampling valve is located in sampling cavity.Its is simple in construction, cost is cheap, making is convenient for production, and by one piece of curved baffle of pipeline interior welds near sampling valve port, when opening respective valves progress normal discharge, normal sampling can be realized by opening sampling valve.So as to avoid in process of production, when opening respective valves progress liquid discharge, Drainage pipe instantaneously forms venturi phenomenon full of high-velocity fluid, causes opening sampling valve can not normally sample phenomenon.
Description
【Technical field】
Beverage production technology field is the utility model is related to, applied to food and drink, chemical industry, pharmaceuticals industry, specially one
The open blowdown on-line period device of kind fluid device.
【Background technology】
In food and drink, chemical industry, pharmaceuticals industry, when fluid device normally produces, fluid needs during discharge
Detection is sampled using sampling valve convection body.It is nearer to sample valve port distance discharge valve port, liquid is carried out when opening corresponding valve port
During discharge, Drainage pipe is instantaneously full of high-velocity fluid, understands that the bigger pressure of speed is smaller by Bernoulli's theorem, so as to form literary mound
In phenomenon, internal pipe pressure is less than external pressure, form negative pressure, therefore cause to open sampling valve and can not normally sample.
【Utility model content】
To solve the above problems, the purpose of this utility model is to provide a kind of can make near sampling valve in sampling region
Fluid is not in the open blowdown on-line period device of negative pressure appearance.
To achieve the above object, the technical scheme that the utility model is taken is：A kind of open blowdown on-line period device, bag
Include Drainage pipe and be arranged on Drainage pipe outside and the sampling valve being connected with Drainage pipe, at the valve port of the sampling valve
Drainage pipe is internally provided with curved baffle, curved baffle opening upwards, and sampling is formed between the inwall of Drainage pipe
Chamber, the valve port of sampling valve are located in sampling cavity.
A kind of open blowdown on-line period device in the utility model is further arranged to：The upper limb of the curved baffle
Not less than the valve port of sampling valve.
A kind of open blowdown on-line period device in the utility model is further arranged to：The upper limb of the curved baffle
/ 3rd of ultimate range not less than the diameter of Drainage pipe between the inwall of Drainage pipe.
Compared with prior art, the utility model has the advantages that：Above-mentioned open blowdown on-line period device,
Its is simple in construction, cost is cheap, making is convenient for production, is kept off by one piece of arc of pipeline interior welds near sampling valve port
Plate, when opening respective valves progress normal discharge, normal sampling can be realized by opening sampling valve.So as to avoid in production process
In, when opening respective valves progress liquid discharge, Drainage pipe instantaneously forms venturi phenomenon full of high-velocity fluid, causes
Phenomenon can not normally be sampled by opening sampling valve.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of curved baffle；
In figure：1st, Drainage pipe, 2, sampling valve, 3, curved baffle, 4, sampling cavity.
【Embodiment】
A kind of open blowdown on-line period device described in the utility model is made below by specific embodiment further
Detailed description.
As shown in figure 1, a kind of open blowdown on-line period device, including Drainage pipe 1 and it is arranged on outside Drainage pipe 1
Portion and the sampling valve 2 being connected with Drainage pipe 1, the Drainage pipe 1 at the valve port of the sampling valve 2 are internally provided with arc gear
Plate 3, the structure of curved baffle 3 are formed between the inwall of Drainage pipe 1 as shown in Fig. 2 the opening upwards of curved baffle 3
Sampling cavity 4, the valve port of sampling valve 2 are located in sampling cavity 4.The upper limb of the curved baffle 3 is not less than the valve port of sampling valve 2.Institute
State three of ultimate range a not less than the diameter of Drainage pipe 1 between the upper limb of curved baffle 3 and the inwall of Drainage pipe 1
/ mono-.
Operation principle of the present utility model is：When opening 1 upper end valve progress fluid drainage of Drainage pipe, high-rate discharge
Fluid flow into Drainage pipe 1, flow through the sampling cavity 4 formed by curved baffle 3 and Drainage pipe 1, now liquid is suddenly herein
Place is interfered, and changes original proper flow state, and produces the fluid of two kinds of different motion states, and produces two in this region
The different pressure of kind and flow velocity, that is, form V as depicted1、P1And V2、P2, and V1Very little.By Bernoulli's theorem flow velocity and pressure
The relation of power understands that speed is small, and pressure is big, i.e. P1Close to upper end pressure P, now lost out in the interface fluid of sampling valve 2
Existing negative pressure shape condition, so as to avoid the generation of venturi phenomenon, can normally be sampled when opening sampling valve 2.
The principle and its effect of the above embodiments only illustrative the invention, and the implementation that part uses
Example, not for limitation the utility model；It should be pointed out that for the person of ordinary skill of the art, this reality is not being departed from
On the premise of being conceived with new creation, various modifications and improvements can be made, these belong to protection model of the present utility model
Enclose.
