Liquid mouth, the inwall of sampling liquid outlet is provided with screw thread.The lower end of vertical portion is connected with horizontal part, and the two ends of horizontal part are separately positioned on
On valve rod 3 in elastic packing cylinder 6, and the two ends of horizontal part are located at elastic packing cylinder 6 and valve rod 3 is tightly connected the lower section at place.
The lower end of valve rod 3 is arranged with seal cap 9, and the top of seal cap 9 offers for being arranged on 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 matching with seal cap 9, and seal cap 9 is passed through
Boss fixes on valve rod 3.The top of seal cap 9 be diameter is gradually reduced from the bottom to top taper such that it is able to preferably with
Elastic packing cylinder 6 matches and sampling runner 13 is sealed.Fixing tabletting 8 is played a supporting role to elastic packing cylinder 6, sealing
The top compression elastic packing cylinder 6 of cap 9, and elastic packing cylinder 6 is pressed on fixing tabletting 8, thus realizing to sampling runner
13 sealing.The bottom of seal cap 9 is taper that from top to bottom diameter is gradually reduced such that it is able to top phase with connecting cavity 12
Cooperation, seals to going out liquor 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 long service life it is not easy to damage, and ethylene propylene diene rubber have well elasticity, to sampling
Runner 13 or go out liquor stream road 11 sealing when, because elastic packing cylinder 6 and seal cap 9 all can occur elastic deformation, substantially increase
Sealing effectiveness, the problem that will not occur to reveal, additionally can enter row buffering to the shock that valve body causes to the movement of valve rod 3,
Thus avoiding valve body 1 and valve rod 3 are damaged, improve service life.
Reset unit is spring 5, and the lower end of spring 5 is supported on the upper surface of valve gap connecting cylinder 7, and upper end is supported on valve rod
3 limiting stand bottom, spring 5 is in compressive state such that it is able to ensure that valve rod 3 is located at initial position, and will sample runner 13
Sealing, it is to avoid ozone gas or Ozone Water are revealed by sampling runner 13, pollutes environment.Because valve rod 3 is polyvinylidene fluoride material
Matter, and metal phase ratio, the intensity of polyvinylidene fluoride is relatively low, in order to avoid the upper end of spring 5 causes to valve rod 3 to damage, 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, it is to avoid spring 5 is to valve
Bar 3 damages.
The operation principle of this Medical sampling three-way 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 valve rod 3 lower end and elastic packing cylinder 6 match, and will sample runner 13 and seal, ozone gas or Ozone Water by
Feed liquor runner 10 flows into, and then flows into out in liquor stream road 11 through connecting cavity 12, and flows out through going out liquor stream road 11, as shown in Figure 1.
During sampling, press valve rod 3, valve rod 3 moves down, and the bottom of the seal cap 9 of valve rod 3 lower end puts in connecting cavity 12
In top, thus connecting cavity 12 is closed, liquor stream road 11 will be gone out and close, meanwhile, seal cap 9 and elastic packing cylinder 6 depart from, and take
The horizontal part of sample runner 13 is connected with feed liquor runner 10, and ozone gas or Ozone Water flow into through feed liquor runner 10, then through elasticity
Sealing drum 6 inner chamber flows in sampling runner 13, and is flowed out by sampling runner 13, completes to sample, as shown in Figure 2.
After the completion of sampling, unclamp valve rod 3, spring 5 promotes valve rod 3 to reset, and seal cap 9 will go out liquor stream road 11 and open, simultaneously
Seal cap 9 is matched with elastic packing cylinder 6, and sampling runner 13 is sealed.
The above, be only preferred embodiment of the present utility model, is not to make other forms to this utility model
Restriction, any those skilled in the art are changed or are modified as being equal to possibly also with the technology contents of the disclosure above
The Equivalent embodiments of change.But every without departing from technical solutions of the utility model content, real according to technology of the present utility model
Any simple modification, equivalent variations and remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
