    The open and close method of pipe ram valve and check valve assembly, when online production slide valve working condition and when online production,Stopping non-return valve when online production, there are three types of working conditions;



    1)

    , when online production slide valve works normally, medium(

    4)

    Pass through medium inlet pipeline(

    1)

    Into flashboard valve core(

    2)

    In closed state, check valve core(

    3)

    In open state, check valve body can be replaced at any time(

    6)

    With check valve core(

    3)

    , medium(

    4)

    Pass through media outlet pipeline(

    7)

    Outflow, screw rod(

    8)

    Retaining is in sealing state;



    2)

    , when online production non-return valve works normally, flashboard valve core(

    2)

    In open state, check valve core(

    3)

    PlaceIn closed state, medium(

    4)

    It is flowed out by media outlet pipeline(

    7)

    , screw rod(

    8)

    Retaining is in running order, prevents non-return valveSpool(

    3)

    It retreats, at this moment flashboard valve body(

    5)

    , flashboard valve core(

    2)

    With check valve body(

    6)

    It can replace online;



    3)

    , in medium inlet pipeline(

    1)

    With media outlet pipeline(

    7)

    Between junction setting be in 0~180 degree angle, when stoppingOnly non-return valve works when online production, medium(

    4)

    Pass through medium inlet pipeline(

    1)

    Into;

    Flashboard valve core(

    2)

    In opening stateState, check valve core(

    3)

    It is directly entered medium inlet pipeline(

    1)

    In closed state, screw rod(

    8)

    Retaining is in sealing state,Media outlet pipeline(

    7)

    In free state;

    The open and close method of Ball valve of pipeline and check valve assembly, when online production ball valve working condition and when online production, stopThere are three types of working conditions for non-return valve when online production:



    1)

    , when online production ball valve works normally, medium(

    4)

    Pass through medium inlet pipeline(

    1)

    Into ball valve core(

    10)

    In closed state, check valve core(

    3)

    In open state, check valve body can be replaced at any time(

    6)

    With check valve core(

    3)

    , medium(

    4)

    Pass through media outlet pipeline(

    7)

    Outflow, screw rod(

    8)

    Retaining is in sealing state;



    2)

    , when online production non-return valve works normally, ball valve core(

    10)

    In open state, check valve core(

    3)

    It is inClosed state, medium(

    4)

    It is flowed out by media outlet pipeline(

    7)

    , screw rod(

    8)

    Retaining is in running order, prevents non-return valve valveCore(

    3)

    It retreats, at this moment ball valve body(

    9)

    , ball valve core(

    10)

    With check valve body(

    6)

    It can replace online;



    3)

    , in medium inlet pipeline(

    1)

    With media outlet pipeline(

    7)

    Between junction setting be in 0~180 degree angle, when stoppingOnly non-return valve works when online production, medium(

    4)

    Pass through medium inlet pipeline(

    1)

    Into;

    Ball valve core(

    10)

    In opening stateState, check valve core(

    3)

    It is directly entered medium inlet pipeline(

    1)

    In closed state, screw rod(

    8)

    Retaining is in sealing state,Media outlet pipeline(
