Abstract
The utility model discloses a valve integrating cycling and sampling functions. The valve comprises a valve body. The valve is characterized in that a medium inlet valve, a medium outlet valve, an inlet and an outlet are formed in the valve body, the medium inlet valve and the medium outlet valve are placed on two faces, opposite to each other, of the valve body, the inlet and the outlet are formed in the same face of the valve body, a sampling valve is located on a face, opposite to the face where the inlet and the outlet are formed, of the valve body, and the sampling valve is placed inside the valve body and is communicated with the medium inlet valve and the medium outlet valve. The valve integrating the cycling and sampling functions has the advantages that the number of connection points is reduced, installation is easy, the number of leakage points is reduced, and the whole valve body is safer.
Description
Technical field
The utility model relates to valve, relates in particular to a kind of valve of circulating sampling one.
Background technique
At present, some petrochemical enterprise all wants sample examination to want tens of times every day, when utilizing existing sampling cock to sample, the sample man will bleed off raffinate or the gas in the valve when sample is taken a sample, raffinate directly is poured on floor drain or directly puts into atmosphere, befouling environment, also personnel are injured, caused economic loss, the sampling cock inconvenient operation, and can cause result of laboratory test inaccurate.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
The model utility content
It is convenient that the purpose of this utility model provides a kind of sampling, and result's circulating sampling accurately is valve core composed.
The technical solution adopted in the utility model is:
A kind of valve of circulating sampling one, comprise valve body, it is characterized in that: described valve body is provided with medium inlet valve, media outlet valve, import and outlet, described medium inlet valve is located at the corresponding two sides of valve body with the media outlet valve, the same one side on the valve body is located in described import and outlet, described import is positioned at the corresponding face of valve body and is provided with sampling valve with outlet, and described sampling valve is built in the valve body and is connected with medium inlet valve and media outlet valve in the valve body.
The utility model has the advantages that: reduced tie point, installed simply, thereby reduced leakage point, made whole valve body safer.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sampling flow chart of the present utility model.
Fig. 3 is circulation process figure of the present utility model.
Wherein: 1, medium inlet valve, 2, sampling valve, 3, the media outlet valve, 4, valve body, 5, import, 6, outlet.
Embodiment
As Figure 1-3, the valve of a kind of circulating sampling one of the present utility model, comprise valve body 4, described valve body 4 is provided with medium inlet valve 1, media outlet valve 3, import 5 and outlet 6, described medium inlet valve 1 and media outlet valve 3 are located at the corresponding two sides of valve body 4, described import 5 and the outlet 6 same one sides of being located on the valve body 4, described import 5 is positioned at valve body 4 corresponding faces with outlet 6 and is provided with sampling valve 5, described sampling valve 2 is built in the valve body 4 and is connected with medium inlet valve 1 and media outlet valve 3 in the valve body 4, reduced tie point, install simple, thereby reduced leakage point, made whole valve body safer.
Working principle:
And the sampling sample pipe import and export welding or thread forms of circulating sampling one valve is connected, open medium inlet valve 1 and media outlet valve 3 before the sampling successively, then sampling valve 2 is terminated in circulation position, sampling valve 2 adopt two direction changeover valves principle, be built in the whole valve body 4, be connected with medium inlet valve 1 and media outlet valve 3 in the valve body 4, after whole valve body 4 is in open mode, after making the medium circulation cycle of the inside, close media outlet valve 3, open sampling valve 2 and be in the sampling location, so definitely the freshness of sample, close sampling valve 2 at last, and medium inlet valve 1.
Claims (1)
