State and be provided with bushing between cock body and the center valve opening inwall；
The bonnet is arranged on the valve body top, and wedge compression ring is provided with the bonnet bottom centre, adjusts spiral shell
Nail is arranged on the bonnet, and the adjusting screw abuts against through the bonnet with the wedge compression ring, by rotating
Adjusting screw is stated to press to the pressure rings so as to adjust the elastic of the cock；
Sampling passage, the sampling external adapter of channel valve, the adapter one are provided with inside the sampling channel valve
The side mating connection channel valve, opposite side mating connection sampling bottle, the adapter inner are provided with interface channel, the company
Connect road and the sampling passage, sampling bottle bottleneck are coaxial.
Rotate the handle, the handle drives the cock to rotate, when the cavity in the cock body of the cock with
During the sample tap docking, external sample is sampled, by the Sample storage in the cavity, continues to rotate institute afterwards
Handle is stated, the cock body, which is rotated further, makes the cavity in the cock body leave the sample tap and be sealed in the center valve opening
In, sampling bottle is connected after the external adapter of the channel valve where sample tap, is ensuring that the sampling passage, the connection are logical
Road, the sampling bottle bottleneck three connection be beeline channel after, rotate the handle until the cock body in cavity again with
The sample tap docking, so as to which the sample in the cavity is transferred in the sampling bottle.
The beneficial effects of the utility model are：
1. quantitative sampling is accurately, conveniently；
It is 2. non-maintaining；
3. cock is easily adjusted；
4. full-bore, easy to clean.
Brief description of the drawings
Fig. 1 is quantitative sampling plug valve stereogram；
Fig. 2 is quantitative sampling plug valve sectional view；
Fig. 3 is the sectional view of cock in quantitative sampling plug valve.
Embodiment
For abundant disclosed purpose, the utility model is done below with reference to drawings and examples further specifically
It is bright.
With reference to quantitative sampling plug valve stereogram and accompanying drawing 2 as shown in Figure 1, quantitative sampling plug valve includes：
Valve body 101, bonnet 103, cock 102 and handle 104；
Wherein, valve body 101 is T-type structure three track valve, and the outer openings sealing of relative two channel valves is close with two
The perpendicular channel valve of channel valve is sealed as sampling channel valve, sampling channel valve outer openings are sample tap；
Bonnet 103 is arranged on the top of valve body 101, and wedge compression ring 106 is provided with the bottom centre of bonnet 103, adjusts spiral shell
Nail 107 is arranged on bonnet 103, and adjusting screw 107 abuts against through bonnet 103 with wedge compression ring 106, is adjusted by rotating
Screw 107 is elastic so as to regulating cock 102 to the pressure of pressure rings 106；
As shown in figure 3, cock 102 includes cock body and valve rod, it is connected by valve rod through bonnet 103 with handle 104, cock body
The cavity 111 of a side opening is inside provided with, the cross sectional shape of opening is circle, and opening can be connected with sampling passage；
Size of the cavity 111 in cock body can be according to sampling amount size sets itself；
Valve opening centered on three passage intersections, in the centrally disposed valve opening of cock body, between cock body and center valve opening inwall
It is provided with bushing 105；
Inside is provided with the external adapter 108 of sampling channel valve of sampling passage, and the mating connection sampling of the side of adapter 108 is logical
Road valve, opposite side mating connection sampling bottle 109, adapter 108 are internally provided with interface channel, interface channel and sampling passage,
Sampling bottle bottleneck is coaxial.
When using quantitative sampling plug valve to be sampled to external agency, rotary handle 104 first, the band of handle 104
Dynamic cock 102 rotates, when the cavity 111 (known cavity volume) in the cock body of cock 102 passes through the opening on cock body and sampling
During mouth docking, external sample is sampled, and by Sample storage in cavity 111, continues rotary handle 104, cock body afterwards
