Description
Technical field
Liquid stream manostatic technique field is the utility model is related to, more particularly to permanent liquid odour seal is depressurized in a kind of water route.
Background technology
In the prior art, it is that the fluid sample to dam online on transfer pipeline is detected during liquid water quality detection, and
Transfer pipeline, which directly samples, can make thief hatch hypertonia, and detecting instrument is caused to damage, and conventional pressure-reducing valve, which reduces, at present adopts
Sample mouth pressure, and pressure-reducing valve downstream pressure can increase and decrease with upstream pressure, while fluid to be measured pressure is beated with pipeline pressure,
And make effect of easing stress limited.
Utility model content
For above description, the purpose of this utility model is that providing a kind of water route depressurizes permanent liquid odour seal, can drop
The hydraulic coupling to be measured that low thief hatch is sampled, and liquid to be checked can be made to keep constant pressure, and can avoids outside air from incorporating, and with compared with
Good using effect.
The technical solution of the utility model is achieved in the following ways：
Depressurize permanent liquid odour seal for a kind of water route, including the interior device body for setting first annular seal space, and positioned at described the
Intrinsic second annular seal space of described device is located above one annular seal space；Also stretched into including one end in the first annular seal space,
The other end stretches into the overflow pipe that the first annular seal space is connected with second annular seal space in second annular seal space, with
And one end is submerged in second annular seal space below the overflow liquid of carrying, the other end through second annular seal space and with the external world
The siphunculus of connection, inlet and test solution outlet are disposed adjacent in the first annular seal space bottom, has been set in the inlet
There is liquid feed valve, liquid valve is provided with the test solution exports.
As restriction, one end that the overflow pipe is stretched into second annular seal space is close at the top of second annular seal space
Set.
Limited as further, the inlet, test solution outlet and overflow pipe three are via described in each communicating with
Liquid in first annular seal space and enclose composition threeway.
As restriction, the groove shape that the bottom of the first annular seal space is trapezoidal is set.
The utility model has the advantage of：
(1) permanent liquid odour seal is depressurized in a kind of water route of the present utility model, by the setting of first annular seal space, will can sample
The liquid of mouth is stored in via inlet in first annular seal space, and part is depressured, meanwhile, pass through the second annular seal space, Yi Jiyi
The setting of flow tube and siphunculus, the liquid in first annular seal space can be made to keep contacting with air indirectly, and made in first annular seal space
Liquid constant pressure；And siphunculus one end is submerged in the second annular seal space below the overflow liquid of carrying so that extraneous air is not turned on the
One annular seal space, and ensure measurement accuracy；
(2) bottom of first annular seal space is set in groove shape, can quickly be updated fluid to be measured, it is less prone to stagnant water.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the permanent liquid odour seal of water route decompression described in the utility model embodiment.
Wherein：
1- first annular seal spaces, the annular seal spaces of 2- second, 3- overflow pipes, 4- siphunculus, 5- inlets, the outlet of 6- test solutions.
Embodiment
, it is necessary to explanation, the orientation of the instruction such as term " on ", " under ", " interior ", " back of the body " in description of the present utility model
Or position relationship is based on orientation shown in the drawings or position relationship, is for only for ease of description the utility model and simplification is retouched
State, rather than instruction or imply signified device or element there must be specific orientation, with specific azimuth configuration and operation,
Therefore it is not intended that to limitation of the present utility model.In addition, term " first ", " second " are only used for describing purpose, and can not
It is interpreted as indicating or implying relative importance.Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The present embodiment is related to a kind of water route and depressurizes permanent liquid odour seal, shown in Fig. 1, including interior sets first annular seal space 1
Device body, and the second annular seal space 2 above first annular seal space 1 and in the device body, in addition to one end stretches
Enter in first annular seal space 1, the other end is stretched into the second annular seal space 2 and overflow what first annular seal space 1 was connected with the second annular seal space 2
Flow tube 3, and one end is submerged in the second annular seal space 2 below the overflow liquid of carrying, the other end through the second annular seal space 2 and with it is outer
The siphunculus 4 of boundary's connection, inlet 5 and test solution outlet 6 are disposed adjacent in the bottom of first annular seal space 1, has been provided with inlet 5
Liquid feed valve, exported in test solution in 6 and be provided with liquid valve.
By the setting of first annular seal space 1, the liquid of thief hatch can be stored in first annular seal space 1 via inlet 5
It is interior, and part is depressured, meanwhile, by the second annular seal space 2, and the setting of overflow pipe 3 and siphunculus 4, can make in first annular seal space 1
