The sealing effect between the spool and shell need to only be handled.Meanwhile being integrally formed the cost that can reduce production assembly.Injection molding
It can make the spool that there is certain plastic deformation ability, can return to the original form after being circumferentially packed into the shell,
Increase sealing performance by the reduced size tolerance of shell described in large-size tolerance fit.Each nozzle of T-type pipe on the flange
Direction is provided with access arrow, convenient for users to observing current pass connection, maloperation, flange is avoided also may be used simultaneously
Think one layer of additional end face seal of increase between the flange side of spool and shell.
Preferably, the column shell is equipped with seal groove far from flange side.
Seal groove is used to enhance the leakproofness without flange side.
Preferably, the centre circle is equipped with seal land corresponding with the seal groove.
After the spool is inserted in the shell, seal land is corresponding with the seal groove chimeric, forms labyrinth seal, described
Labyrinth seal realizes better seal in a manner of increasing flow path of the liquid complexity.
Preferably, the centre circle, which connects the flange side, is equipped with limiting slot, 45 ° of the limiting slot both sides are arranged with limit
Position rib.
With 45° angle arranged for interval, the spool corresponding can quantitatively be rotated with 45° angle for the limiting slot and place-limited edge,
Ensure that rotation core amount of spin when each unicom form switches determines, is not in be sent out between the seal and the through-hole
The case where raw misalignment.
Preferably, being equipped with shift plate at the top of the flange.
The shift plate can determine the initial position of the spool by shift plate perpendicular to the flange.Operating personnel can
To stir the spool by shift plate with lever principle labour-saving.
Preferably, being equipped with limited post below the shift plate.
The limited post and the shift plate are in the same direction, and the limited post can be chimeric with the limiting slot.When the limited post
When chimeric with the limiting slot, spool is in initial position, is not connected between the T shapes pipe and through-hole at this time, is in closed state.
When adjusting the limited post rotation and both sides place-limited edge only supports, T shape pipes are connected to the flush-through connection and operating head connector or suction
Draw connector and operating head connector, realizes the switching between two working conditions of attraction/flushing.
Preferably, the shift plate is equipped with top stop.
The block can be such that its finger only supports when operator operates, and easily rotate the spool.
Preferably, the shift plate side is equipped with corrugated part.
The corrugated part is in wavy, and larger friction is provided between finger and shift plate in operating personnel's rotational valve core
Power avoids the maloperations such as skidding caused by the humidity between finger and shift plate.
Preferably, the flush-through connection, attraction connector are multi-stage taper sealed fitting, operating head connector connects for screw thread
Head.
Quick-speed plug and the sealing of flexible pipe for medical purpose may be implemented in the sealed fitting of taper.Nipple can be connected effectively
The irrigation and drainage pipeline.
The beneficial effects of the utility model are：Dismountable spool design reduces in disinfecting process to rinsing flow diverter
Life consumption, integrated spool design reduces production cost while increasing convenience, leakproofness, passes through a variety of limits
Device and sealing device ensure that it is removable in the case of install spool accuracy, the accuracy and leakproofness used.This practicality is new
Type has simple in structure, favorable working performance, advantage at low cost.
