Abstract
The utility model discloses a float valve of a rotary switch of a ceramic valve core, which comprises a valve body, a valve seat, a valve disc, a connecting rod, a float, a core shaft and a spring, wherein the valve seat is arranged in the valve body, the valve disc is arranged on the upstream side of the valve seat, the spring is arranged on the upstream side of the valve disc, the downstream side of the valve disc is connected with the core shaft, the core shaft penetrates the valve seat and is connected with one end of the connecting rod, the other end of the connecting rod is connected with the float, and both the valve seat and the valve disc are provided with runner holes. The float valve adopts a rotary ceramic valve core, the operation force of the valve is less impacted by the pressure of an inlet, and the volume of the float is correspondingly reduced, thereby avoiding the phenomenon of fatigue fracture of the connecting rod due to excessive buoyancy of the float.
Description
Technical field
The utility model relates to a kind of float valve, is specifically related to a kind of ceramic valve core rotary switch float valve.
Background technique
Existing flush toilet is used to control the float valve of cistern water level, exists ball float excessive, the fracture of valve rod fatiguability, defective such as working life is short.In case valve damages, water tank water overflows, waste water resource.
The model utility content
Technical problem to be solved in the utility model provides a kind of ceramic valve core rotary switch float valve, and it can solve, and existing float valve ball float is excessive, and connecting rod is easy to fracture, valve short problem in working life.
For solving the problems of the technologies described above, the technical solution of the utility model ceramic valve core rotary switch float valve is:
Comprise valve body, valve seat, valve disc, connecting rod, ball float, mandrel, spring; Valve seat is arranged in the valve body, and the upstream side of valve seat is provided with valve disc; The upstream side of valve disc is provided with spring, and the downstream side of valve disc is connected with mandrel, and mandrel passes valve seat, is connected with an end of connecting rod, and the other end of connecting rod connects ball float; Valve seat and valve disc are equipped with the runner hole.
One end of described spring is fixed, and the other end props up the upstream side of valve disc; The surface of contact of valve seat and valve disc is a seal face.
Be provided with the gap between described mandrel and the valve seat.
The technique effect that the utility model can reach is:
The utility model adopts the rotary type ceramic spool, so the steering force of valve is subjected to the influence of inlet pressure less, and therefore the corresponding volume that reduces ball float can be avoided because the excessive phenomenon that causes the connecting rod fatigue fracture of buoyancy of ball float.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model ceramic valve core rotary switch float valve;
Fig. 2 is the structural representation of valve seat.
Description of reference numerals among the figure:
1 is valve disc, and 2 is valve seat, and 21 is the runner hole,
3 is valve body, and 5 is spring, and 6 is ball float,
7 is mandrel, and 8 is connecting rod.
Embodiment
As shown in Figure 1, the utility model ceramic valve core rotary switch float valve comprises valve body 3, valve seat 2, valve disc 1, connecting rod 8, ball float 6, mandrel 7, spring 5; Valve seat 2 is fixedly set in the valve body 3, and the upstream side of valve seat 2 is provided with valve disc 1; The upstream side of valve disc 1 is provided with spring 5, and the downstream side of valve disc 1 is fixedly connected with mandrel 7, after mandrel 7 passes valve seat 2, fixedlys connected with an end of connecting rod 8, and the other end of connecting rod 8 connects ball float 6.Be provided with the gap between mandrel 7 and the valve seat 2, be convenient to the rotation of mandrel 7.
As shown in Figure 2, valve seat 2 is provided with runner hole 21.The runner hole that also is provided with shape on the valve disc 1 and distributes similar.When valve disc 1 did not cover the runner hole 21 of valve seat 2 fully, valve was in the state of unlatching, and when valve disc 1 covered the runner hole 21 of valve seat 2 fully, valve was in closed condition.
When water level rose or descend, ball float 6 was under buoyancy function, and ball float 6 moves up and down thereupon; The motion of ball float 6 drives mandrel 7 rotations by connecting rod 8; The rotation of mandrel 7 drives 1 rotation of fixedly connected with it valve disc, thereby realizes the open and close of valve.
The utility model adopts the rotary type ceramic spool, so the steering force of valve is subjected to the influence of inlet pressure less, and therefore the corresponding volume that reduces ball float 6 can be avoided because the excessive phenomenon that causes connecting rod 8 fatigue fractures of buoyancy of ball float 6.
The utility model adopts ceramic valve core, and promptly valve seat 2 and valve disc 1 all adopt stupalith, can prolong the working life of valve.
Mandrel 7 of the present utility model is positioned at the downstream of valve, so need not to seal between mandrel 7 and valve disc 1 and the valve seat 2, and structure is simpler.
