Described spring offer elastic force makes two sealing rings with the trend near valve element and so that the concave panel of fluorubber ring is fitted all the time
In spool face.
This ball valve makes it have check function in check-valves is set in delivery port, and the through hole of valve element bottom causes water
Stream can enter in the cavity formed between sealing ring, valve rod, valve element and valve body so that the current in cavity form flowing to protect
Cleaning is held, it is to avoid bacteria breed in cavity, the wearability of fluorubber ring is good in addition, long service life, even if after long-time use
There are some abrasions in fluorubber ring, and the elastic force of spring also causes that the concave panel of fluorubber ring fits in spool face all the time, it is ensured that
Sealing, ball valve will not leak.
In a kind of above-mentioned ball valve, middle part is equipped between the outer face of described two sealing rings and corresponding shoulder block and is opened
The support pad of water hole is provided with, one end of two springs contacts at the bottom of correspondence mounting hole, and the other end of two springs is supported
Touch in support pad on.Support pad avoids spring that crushing is caused to sealing ring, and good to the support effect of sealing ring.
In a kind of above-mentioned ball valve, the quantity of described through hole is one and is arranged on the center of valve element bottom.
So valve element processing is simple, and the mechanical strength influence on valve element is small.
In a kind of above-mentioned ball valve, described handle is fixedly connected with by screw with valve rod.In some occasions, user can
By under screw and handle release, it is to avoid other people steal water.
In a kind of above-mentioned ball valve, at least two sealing rings are provided between described valve rod and valve body.So valve rod and
Good airproof performance between valve body.
Compared with prior art, this ball valve has check function, it is to avoid sewage backflow, and cleaning effect is good, it is to avoid thin
Bacterium grows, in addition good airproof performance, long service life.
