In valve chamber 221, when which is located at first position, drain outlet is switched on, when which is located at the second position, blowdown
Channel disconnects.In this way, can realize the drainage clean of liner by the position of switching spool 23.Wherein, switching mode can be with hand
It is dynamic or electronic.
In some alternative embodiments, the slewing area of spool 23 is between 0-90 °.That is the open position and closing of spool 23
The slewing area of position is 90 °.
In a specific embodiment of the utility model, spool 23 is ball valve core, and ball valve core is equipped with valve shaft 231, passes through
Valve shaft 231 is rotated with movable valve plug 23.Wherein, the peripheral wall of valve body 22 is equipped with mounting hole 222, and spool is fixed in one end of valve shaft 231
On 23, the other end of valve shaft 231 wears mounting hole 222 and is located at the outside of mounting hole 222, the circumferential surface and mounting hole of valve shaft 231
Second seals structure 26 is equipped between 222 inner peripheral surface.That is, spool 23 can be rotated around valve shaft 231, pass through valve shaft
231 rotation band movable valve plug 23 rotates between the first position and the second position.Wherein, valve shaft 231 be located at exterior portion can be with
Handle is connected, the manual rotary spool 23 of user is convenient for.
Further, since sewage pipe 10 is connect with blowdown valve 20 by first flange structure and second flange structure, and therefore, valve
The position of axis 231 be it is relatively fixed, there is no be connected through a screw thread azimuth zeroset.
In some alternative embodiments, as shown in figure 3, blowdown valve 20 further include: position limiting structure 24.Position limiting structure 24 is set to valve
The lower end of body 22 is for supporting spool 23.Spool 23 is limited in the displacement of vertical direction by position limiting structure 24.Wherein, it limits
Bit architecture 24 is the hollow screw of both ends open, and the inner surface of valve chamber 221 has the internal screw thread of hollow screw cooperation.Pass through screw thread
Mode cooperates, and fast implements the cooperation of position limiting structure 24 Yu valve body 22, improves the assembly efficiency of blowdown valve 20.
In some optional examples, the top and bottom of spool 23 are respectively equipped with the first sealing structure 25 with cambered surface, from
And when drain outlet being prevented to be in an off state, water seeps at spool 23 and valve body 22, the cooperation of spool 23 and position limiting structure 24
