Flow direction of Y-type stop valve
Classification:
Release Time：2017-09-08
Y-type globe valve is the most common use of a valve, due to the opening and closing process between the cover of the friction is small, more durable, open height is not, easy to manufacture, convenient maintenance, so welcomed by the majority of customers. The closing principle of the Y-type stop valve is to rely on the pressure of the valve bar to make the valve clack sealing surface and the valve seat sealing surface closely fit to prevent the circulation of the medium. Y type stop valve medium for one-way flow, installation with directional. Y type cut-off valve body structure in the form of straight-through, straight-through and right-angle type. The straight-through type is the most common structure, but its fluid resistance is the greatest. Direct flow fluid resistance is small, mostly used for solid particles or sticky.

Y type cut-off valve body structure in the form of straight-through, straight-through and right-angle type. The straight-through type is the most common structure, but its fluid resistance is the greatest. Direct flow fluid resistance is small, more for containing solid particles or high viscosity of the fluid. Right angle type valve body using forging,YType A cut-off valve is suitable for small pass and high pressure cut-off valves.
Y type valve has the following advantages:
(1) The structure is simple, and the manufacturing and maintenance are convenient.
(2) The working stroke is small and the opening and closing time is short.
(3) good sealing, sealing surface friction between small, long life.
Y type valve shortcomings are as follows:
(1) The fluid resistance is large, and the force required for opening and closing is large.
(2) It is not suitable for media with particles, high viscosity and easy coking.
(3) poor regulation performance.
