Flow direction, it only needs just can be closed tightly with the rotating torque of operation for being rotated by 90 ° and very little, and ball valve optimum is done
Switch, stop valve use, and V-type ball valve, electrically operated valve still should be specifically noted that its environment item used in addition to it should be noted that pipe parameter
Part, since the electric device in electrically operated valve is an electromechanical equipment, use state is influenced very big, usual shape by its use environment
Under state, electrical ball valve, butterfly valve in following environment using paying special attention to, since the spool of hard seal ball valve is steel alloy surfacing,
Sealing ring is steel alloy built-up welding, so hard seal ball valve will not generate too big abrasion in switch, due to hard seal ball valve
Sealing be using underhand polish, until spool and sealing ring fit like a glove and could use, so his sealing performance is reliable,
Since the sealing ring bottom of hard seal ball valve makes sealing ring tightly be embraced together with spool using spring, so surpassing in extraneous strength
It switchs very light during the pretightning force for crossing spring, is widely used to oil, chemical industry, power generation, papermaking, atomic energy, aviation, rocket etc.
In each department and people's daily life.
On the basis of the technical conditions of existing ball valve, still remained in the range used and convenience of valve seat
Many insufficient, most Two-way flow ball valve leakproofness during long-time use is poor, and the safety used is relatively low, exists
Serious security risk, easily occurs maloperation, influences the normal use of ball valve.
