Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0021] refer to Figure 1-2 As shown, a three-way plastic ball valve includes a valve body 1, a handle, a fine ball 2, a ball rod and a seal, wherein, the valve body 1 is provided with an A channel 11, a B channel 12 and a C channel 13, and the A channel 11 , the axis lines of channel B 12 are on the same horizontal line, the axis lines of channel C 13 are perpendicular to the axis lines of channel A 11 and channel B 12; the fine ball 2 is provided with channel D 21, channel E 22 and channel F Channel 23, the axes of D channel 21 and E channel 22 are on the same horizontal line, and the distribution is concentric and in the same direction as A channel 11 and B channel 12. The center lines are perpendicular to each other and are concentric and i...

Abstract

The invention relates to a three-way plastic ball valve, and belongs to ball valves. The three-way plastic ball valve comprises a valve body, a handle, a fine ball, a ball rod and a sealing part. The valve body and the fine ball are made of pcv materials, and a channel A, a channel B and a channel C on the valve body are each detachably provided with a connecting head for being connected with pipelines; bearing bodies are arranged on the connecting heads, and the bearing bodies extend inwards until the bearing bodies are in contact with the fine ball; first sealing rings are arranged on the bearing bodies, and a second sealing ring is arranged at the end, opposite to the channel C, in the valve body; the fine ball is fixedly arranged in the valve body through the three first sealing rings and the second sealing ring. Due to the fact that the valve body and the fine ball are made of the pcv materials, under the high-temperature condition, the clamping phenomenon of the fine ball and the valve body cannot appear; meanwhile, due to the fact that the sealing rings are arranged on the connecting heads, the fine ball is completely suspended in the valve body, and operation is flexible; and due to the fact that the connecting heads are detachably connected with the valve body, the sealing part can be easily disassembled and replaced, and the water leakage phenomenon is reduced.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a three-way plastic ball valve. Background technique [0002] With the continuous development and technological progress of plastic pipelines, the demand for matching plastic valves is getting higher and higher, and more advanced plastic ball valves need to be continuously developed. Generally, existing plastic ball valves usually consist of parts such as a valve body, a handle, a precision ball, a ball rod, and a sealing ring. Usually, the material of the center of the ball is pp and the material of the outer shell is pvc. Since the ball and the valve body are made of different plastics, the ratios of thermal expansion and contraction of the two materials are different, so once the product passes through the sun Exposure to the internal sphere expands, and the sphere wants to contact the valve body, making the fine ball unable to rotate; on the other hand, since most of the...
