Tribit intercommunication valve

The utility model provides a tribit intercommunication valve, including valve body and case subassembly, the valve body comprises base and last lower cover, and the valve body side is equipped with three connection pipeline's the through -hole that the area is equal, and the through -hole includes feed liquor hole, first liquid hole and second play liquid hole, the central line in feed liquor hole is perpendicular with the central line in first liquid hole, and the central line that goes out the liquid hole with the second is the T type on same straight line. The case subassembly includes the case body and connects the turtleback board on the case body with the vaulting pole. The utility model provides a tribit intercommunication valve, the design is simple, and processing is convenient, and is with low costs, and through the structure of design arc valve plug, but scene 2 liquid hole goes out liquid simultaneously, and has realized when open totally in the feed liquor hole, and effect that the long -pending sum of play liquid level in scene 2 liquid hole always equals with the feed liquor area in feed liquor hole makes the liquid velocity of flow keep invariable, specially adapted automation constant temperature control system.
