Detailed Description
The first embodiment is as follows:
the embodiment provides a valve body component, as shown in fig. 2, comprising a gate plate 2 and a valve housing 5, wherein the gate plate 2 is in a wedge-shaped structure, a groove 51 matched with the gate plate 2 is formed on the surface of the valve housing 5, and the end of the gate plate 2 can move up and down in the groove 51 to realize the conduction or the cutoff of a fluid medium passing through the valve body.
In this embodiment the valve sleeve 5 is an elastic valve sleeve, for example a polyurethane valve sleeve.
The one end that flashboard 2 and valve barrel 5 matched with is the mating end, and the terminal surface of valve barrel 5 mating end is the fitting surface. A first inclined surface is formed on one side of the matching surface, and a second inclined surface corresponding to the first inclined surface is formed on the side wall of the groove 51; the bottom surface of the groove 51 is a horizontal surface adapted to the mating surface.
The inner wall of the groove 51 opposite to the second inclined surface is provided with a first step 52, one side of the gate plate 2 opposite to the first inclined surface is provided with a second step 21, and one side of the second step 21 facing the matching surface is provided with a set slope angle 22.
Due to the arrangement of the first step 52, the second step 21 and the slope angle 22, the valve sleeve 5 cannot be extruded and damaged by the gate plate 2 when the knife gate valve is turned off, and meanwhile, the sealing of the valve can be realized, and zero leakage is realized.
In order to ensure the sealing performance of the valve, the slope angle of the embodiment ranges from 10 degrees to 80 degrees.
Example two:
the embodiment provides a knife gate valve, which comprises a valve body member as described in the first embodiment, and further comprises a driving mechanism, a first valve body 3 and a second valve body 4, as shown in fig. 1, one side surfaces of the first valve body 3 and one side surface of the second valve body 4 are attached to each other, and the first valve body 3 and the second valve body 4 are detachably connected; the driving mechanism is connected with the flashboard 2 and can drive the flashboard 2 to move up and down.
