    • 专利摘要:
    A fluid flow control valve has a body 28, enclosing a transfer passageway whose bounding surface is profiled to provide streamline flow conditions. The passageway is constricted by means of a piston-like valve 32 moving transverse to the direction of fluid flow. A profiled shield 36, protects the valve 32 from direct impingement of fluid.

    专利说明:

    The invention relates to valves for controlling the flow of a fluid, in particular to control valves installed in gas pipes.
    Known control valve, in the case of which with two bypass channels mounted rod with fixed on it two shut-off bodies With 1 1
    The drawbacks of the device are its increased dimensions and the need to ensure the simultaneous closure of two closure members.
    Also known is a control valve containing a locking organ fixed on the rod and a discharging piston 2 J located opposite it.
    However, this valve is characterized by insufficient unloading efficiency (i.e. a decrease in the effect of unbalanced forces).
    Closest to the invention to the technical essence and the achieved result is a control valve, in the case of which a stop valve is interposed, which interacts with the saddle and is made with a discharge chamber C 3 3.
    However, the known device is also characterized by a lack of effectiveness of the balancing effort, and consequently, lowered operational qualities.
    The aim of the invention is to increase the performance of the control valve.
    This goal is achieved by the fact that in a control valve, in the case of which a shut-off member interacting with the saddle is placed, filled with a discharge chamber, in the flow part of the case adjacent to the valve seat, perpendicular to the flow direction, a hollow fairing is rigidly connected to the case. the locking member is made in the form of a hollow piston-like element installed with the possibility of axial movement in the fairing cavity, between which the sealing element is placed between the locking member and forming the uzochnuyu chamber communicating with the flow-through part of the housing of the saddle surface.
    The drawing shows a control valve, a slit.
    The control valve includes a housing 1 having located below
    downstream chamber 2 and upstream - chamber 3, the inner surfaces of which are profiled, which allows reducing the turbulence of the flow. A valve body is installed in the valve body 1, made in the form of a hollow piston-like element 4, fixed to the rod 5 by means of a hex nut 6 and placed in the cavity of the fairing 7 with the possibility of axial movement. The fairing 7 is installed in the flow-through part of the housing 1 perpendicular to the direction of flow of the working medium and is complete
    5 of two parts, upper, fixed to housing 1 by jumpers 8, and lower, attached to the upper part by bolts 9. The rod 5 is guided in the support plates 10 of the deflector 11 of the housing 10. Between the fairing 7 and the closure body in the form of a hollow piston-like element 4 is placed sealing element 12 of the membrane type, forming a discharging chamber 13, isog
    5 from the upstream part of the working medium flow. In the rod 5 is made bypass channel 14, indicating the cavity of the discharge chamber 13 with the pressure of the working environment
    downstream. The upper part of the hollow piston-like element 4 has a sealing lip 15 which cooperates with the seat 16.
    The operation of the control valve is carried out as follows.
    When moving the actuator (not shown) of the rod 5, the locking member is opened or closed in the form of a hollow piston-like element 4 and,
    therefore, the medium is controlled.
    The balancing of the forces acting on the control valve is achieved by using a closure member,
    with a hollow piston-like element 4 and a flap 7 protecting the piston-like element 4 from the impact of a fluid medium, as well as profiling the surfaces of the parts
    Valve under the influence of fluid flow.
    The use of the sealing element 12 of the membrane type prevents the influence of the flow of the working medium on the front surface of the valve.
    The concentric design of the valve and its moving parts allows the valve to be mounted coaxially inside the valve body, and
