The service life of plunger stop valve.
Brief description of the drawings
Fig. 1 is the structural representation of plunger stop valve of the present utility model；
In figure mark for：Valve body 1, feed pathway 11, liquid outlet channel 12, the first seal groove 13, bonnet 2, plunger 3, handwheel
4, sealing unit 5, back bracket ring 51, sealing ring 52, pH value tester 6, valve pocket 7, connecting key 8, flange 9, the second seal groove 91.
Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein
Same or similar label represents same or similar element or the element with same or like function from beginning to end.Lead to below
It is exemplary to cross the embodiment being described with reference to the drawings, it is intended to for explaining the utility model, and it is not intended that to this practicality
New limitation.
As shown in figure 1, the present embodiment provides a kind of plunger stop valve, including valve body 1, the valve that is connected with the valve body 1
The handwheel 4 of lid 2, the plunger 3 being arranged in the valve body 1 and the driving plunger, the valve body 1 are provided with feed pathway 11
With liquid outlet channel 12, the valve body 1 sets the first seal groove 13, and the valve body 1 is with the plunger 3 by being arranged at the sealing
Sealing unit 5 in groove 13 seals, and is provided with the valve body 1 and is communicated to the feed pathway 11 or the liquid outlet channel 12
PH value tester 6.The handwheel 4 drives the plunger 3 to rotate, so that the feed pathway 11 and the liquid outlet channel
12 connections are closed；Set on the valve body 1 and be communicated to the feed pathway 11 or the pH value of the liquid outlet channel 12
Tester 6, can detect the pH value of flowed through liquid, learn the acid-base value of liquid in time, so as to which liquid be adjusted, such as
Fruit pH value is abnormal, such as in it is stronger acid or alkaline when, then liquid is abnormal, it is necessary to which artificial timely processing, improves security
While energy, the service life of the plunger stop valve is extended.
The bottom of the pH value tester 6 is located at the lower section of the center line of the feed pathway 11 or liquid outlet channel 12.
The bottom of pH value tester 6 is located at the lower section of the center line of the feed pathway 11 or the liquid outlet channel 12, so, described
PH value tester 6 can fully contact with liquid, and testing result is more accurate, and when the amount of liquid flowed through is less, still can be with
Detected.
Valve pocket 7 is provided between the plunger 3 and the bonnet 2, the valve pocket 7 is locked with the bonnet 2 by connecting key 8
It is fixed.Setting valve pocket 7 between 2 and the plunger 3 is issued described, sealing and dustproof can be played；The side locked by connecting key 8
