Internal diameter is less than lower inner diameter, and the middle part of bonnet connecting cylinder 7 is the tapered transitional that internal diameter is gradually reduced from top to bottom.
Sampling runner 13 includes the vertical portion on top and the horizontal part of bottom, and vertical portion is coaxially disposed with valve rod 3, and vertically
The diameter of the upper end in portion is more than the diameter of bottom, goes out so as to be formed in the upper end of vertical portion for the convenient sampling being connected with pipeline
Liquid mouth, the inwall for sampling liquid outlet are provided with screw thread.The lower end of vertical portion is connected with horizontal part, and the both ends of horizontal part are separately positioned on
On valve rod 3 in elastic packing cylinder 6, and the both ends of horizontal part are located at elastic packing cylinder 6 and the lower section at the sealed connection of valve rod 3.
The lower end of valve rod 3 is arranged with seal cap 9, and the top of seal cap 9 is offered for the perforate on valve rod 3,
The upper-end inner diameter of perforate is less than the internal diameter of lower end, and the lower end of valve rod 3 is provided with the boss being engaged with seal cap 9, and seal cap 9 passes through
Boss is fixed on valve rod 3.The top of seal cap 9 is diameter is gradually reduced from the bottom to top taper, so as to preferably with
Elastic packing cylinder 6 is engaged to be sealed to sampling runner 13.Fixed tabletting 8 is played a supporting role to elastic packing cylinder 6, is sealed
The top of cap 9 compresses elastic packing cylinder 6, and elastic packing cylinder 6 is pressed in fixed tabletting 8, so as to realize to sampling runner
13 sealing.The bottom of seal cap 9 is the taper that from top to bottom diameter is gradually reduced, so as to the top phase with connecting cavity 12
Coordinate, sealed to going out liquid stream road 11, good sealing effect, and will not be due to the effect of attrition sealing effectiveness of connecting cavity 12.
The material of elastic packing cylinder 6 and seal cap 9 is ethylene propylene diene rubber, on the one hand facilitates elastic packing cylinder 6 and close
The making of sealing cap 9, and service life is grown, it is not easy to damage, and ethylene propylene diene rubber has elasticity well, to sampling
Runner 13 or go out liquid stream road 11 seal when, because elastic deformation can occur for elastic packing cylinder 6 and seal cap 9, substantially increase
Sealing effectiveness, the problem of will not revealing, movement that additionally can be to valve rod 3 is hit to caused by valve body into row buffering,
So as to avoid that valve body 1 and valve rod 3 are damaged, service life is improved.
Reset unit is spring 5, and the lower end of spring 5 is supported on the upper surface of bonnet connecting cylinder 7, and upper end is supported on valve rod
3 limiting stand bottom, spring 5 are in compressive state, so as to ensure that valve rod 3 is located at initial position, and will sample runner 13
Sealing, avoids ozone gas or Ozone Water from being revealed by sampling runner 13, pollutes environment.Because valve rod 3 is polyvinylidene fluoride material
Matter, with metal phase ratio, the intensity of polyvinylidene fluoride is relatively low, valve rod 3 is caused to damage in order to avoid the upper end of spring 5, in bullet
Spring shim 4 is set between the upper end of spring 5 and valve rod 3, and spring shim 4 can be protected to valve rod 3, avoid spring 5 to valve
Bar 3 damages.
The operation principle of this Medical sampling triple valve is as follows：During normal use, spring 5 promotes valve rod 3 to be located at initial position,
Now the seal cap 9 of the lower end of valve rod 3 and elastic packing cylinder 6 are engaged, and sampling runner 13 is sealed, ozone gas or Ozone Water by
Feed liquor runner 10 flows into, and is then flowed into out through connecting cavity 12 in liquid stream road 11, and is flowed out through going out liquid stream road 11, as shown in Figure 1.
During sampling, valve rod 3 is pressed, valve rod 3 moves down, and the bottom of the seal cap 9 of the lower end of valve rod 3 puts in connecting cavity 12
In top, so as to which connecting cavity 12 be closed, liquid stream road 11 will be gone out and closed, meanwhile, seal cap 9 and elastic packing cylinder 6 depart from, and take
The horizontal part of sample runner 13 connects with feed liquor runner 10, and ozone gas or Ozone Water flow into through feed liquor runner 10, then through elasticity
The inner chamber of sealing drum 6 is flowed into sampling runner 13, and is flowed out by sampling runner 13, completes sampling, as shown in Figure 2.
After the completion of sampling, valve rod 3 is unclamped, spring 5 promotes valve rod 3 to reset, and seal cap 9 will go out liquid stream road 11 and open, simultaneously
Seal cap 9 is engaged with elastic packing cylinder 6, and sampling runner 13 is sealed.
The above described is only a preferred embodiment of the present invention, being not the limitation for making other forms to the present invention, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But it is every without departing from technical solution of the present invention content, the technical spirit according to the present invention is to above example institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection domain of technical solution of the present invention.
