Abstract
The invention discloses a draining valve structure with the small operating force value. The draining valve structure comprises a valve body and a valve element used for controlling a draining valve to be opened and closed; the valve element is movably arranged on the valve body, and at least one rolling part is arranged between the valve element and the valve body, can be assembled in one of the valve element and the valve body in a rolling manner, and is in rolling fit with the other one of the valve element and the valve body; in the opening and closing process of the draining valve, the valve element is relatively and movably matched with the valve body through the rolling parts, and therefore a friction coefficient between the valve body and the valve element is reduced, and the operating force of the draining valve is smaller; and a key or wrench is not prone to being clamped, and the old or children with the small strength can conveniently use the key or wrench.
Description
Technical field
The present invention relates to bathroom technical field, particularly relate to a kind of handle the drain valve structure that force value is little.
Background technology
Existing water tank drain valve, it is moved up and down by spool and opens or seal discharge outlet, drain valve
Inside be provided with guiding parts, during spool moves up and down, spool and guiding parts guiding coordinate so that
Spool up and down motion is more stable reliably, and existing guiding parts is typically all gathering sill or guiding rib, spool
Being correspondingly provided with guiding rib or gathering sill, spool realizes slip with guiding parts by gathering sill and guiding rib and leads
To.Owing to being slidably matched so that spool and guiding parts coefficient of friction therebetween are relatively big, so press
Button or to pull spanner relatively big to be lifted up manipulation force value required for spool, during use button or
Spanner easily blocks and cannot realize draining, and old man or child that especially inconvenience strength is little use.
Summary of the invention
The present invention solves the problems referred to above, it is provided that a kind of handle the drain valve structure that force value is little, it passes through
Between valve body and spool, increase rolling member, thus effectively reduce the coefficient of friction between valve body and spool,
