  • Hydraulic control valve

    Hydraulic control valve

    In the mid-to-late 1990s, domestic manufacturers introduced foreign technology--T-diaphragm and Y-diaphragm hydraulic control valves, and developed similar products after digestion and absorption. Its main product forms are as follows: T diaphragm type (100X type), Y diaphragm type (745X type), T type piston type and Y type piston type. Among them, the piston type hydraulic control valve is a domestic original product.

  • gate

    gate

    The gate valve is a gate of the opening and closing piece. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel and so on. The gate has a rigid gate and an elastic gate. According to different gates, the gate valve is divided into a rigid gate valve and an elastic gate valve.

  • Shut-off valve

    Shut-off valve

    The shut-off valve, also called a shut-off valve, is a forced-sealed valve. When the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the valve disc, the resistance to be overcome by the operating force is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve. The diameter must be large, otherwise the valve top bending failure will occur. There are three types of connection: flange connection, screw connection and welding connection. After the self-sealing valve appeared, the medium flow direction of the shut-off valve changed from the upper part of the valve disc into the valve cavity. At this time, under the action of the medium pressure, the force to close the valve is small, and the force to open the valve is large, and the diameter of the valve stem can be corresponding To reduce. At the same time, this type of valve is also tight under the action of the medium.

  • Check valve

    Check valve

    Check valve refers to the valve that automatically opens and closes the valve flap based on the flow of the medium itself to prevent the medium from flowing backward. It is also known as a check valve, check valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve, and its main function is to prevent the medium from flowing backward, to prevent the pump and the drive motor from reversing, and to release the medium from the container.

  • Ball valve

    Ball valve

    Ball valve (ball valve) is defined in the standard GB / T21465-2008 "Terms of Valve": a valve that is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-ball valve has a strong shear force between the V-shaped core and the metal valve seat of the hard alloy, which is especially suitable for fibers and small solid particles. And other media. The multi-way ball valve can not only flexibly control the confluence, divergence, and flow direction of the medium on the pipeline, but also can close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve according to the driving mode.

  • Butterfly valve

    Butterfly valve

    Butterfly valve, also known as flap valve, is a simple structured regulating valve, which can be used for the switch control of low-pressure pipeline media. The closing valve (disc or disc) is a disk that rotates around the valve shaft to achieve opening and closing. Kind of valve. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, muds, oils, liquid metals and radioactive media. It mainly plays a role of cutting off and throttling on the pipeline. The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting.
