Release Time：2018-01-18
Y type cut-off valve is mainly used in the hydraulic system of a valve, mainly to the work of the switch. Y type cut-off valve is the main opening and closing device. The sealing surface of Y-type globe valve is mainly divided into two ways: plane and cone. Y type cut-off valve is a straight line along the center line of the oil movement, movement is mainly divided into the following. One of them is the lifting type valve stem, which is mainly the lifting of the valve stem during the movement and the pulley does not move. Another is the lifting rotation mode of the valve stem, the stem of the cut-off valve is set on its nut, the movement of the valve stem and hand wheel to do rotary lifting. Currently, the Y

Another is the lifting rotation mode of the valve stem, the stem of the cut-off valve is set on its nut, the movement of the valve stem and hand wheel to do rotary lifting. At present, the Y-type valve is mainly used for fully open or fully closed work.
Y type cut-off valve is a mandatory sealed valve, so we must put pressure on the cut-off valve flap to close the valve of the Y type cut-off valve. In this way, the mandatory pressure on the cut-off valve can ensure that the sealing surface will not leak. And when the oil through the disc into the valve flow, we need to overcome the impeding force to operate, the impeding force is mainly the friction between the valve stem and packing and a thrust generated by the pressure of the medium, so in daily operation We often find that the force used to avoid opening the Y-type stop valve is much smaller than the force used to close the Y-type stop valve. Therefore, the Y-type globe valve is closed with a larger diameter stem design concept to ensure that the stem will not be due to the operator to use too much force and failure problems.
Y-type globe valves are plate-mounted valves, and no leakage and good sealing, and the installation of steel ball structure. Y-type globe valve through the lever or push rod control valve work, its basic structure is 2/2 and 3/2 directional valve. When the two directional valves are combined together, 3/3 and 4/3 directional valves can be realized, and 4/2 directional valves can be formed by using intermediate plates. The variant of the Y-type stop valve is used as a long-term strain and high-switching frequent reinforcement structure for boundary fluctuations in the upper pressure range. Y-type globe valve using plate connecting block can be composed of pipe-connected valve, but also can link other functions of the overflow valve or bypass check valve to further expand the application, you can also use multiple valves in parallel to form a valve group.
Y-type globe valve allows only one-way flow of media, directional installation. The structure length of the stop valve is larger than the gate valve, and the fluid resistance is large.
