Problems solved by technology

Due to the sliding fit, the coefficient of friction between the spool and the guide parts is relatively large, so pressing the button or pulling the wrench to lift the spool requires a large amount of operating force, and the button or wrench is easy to get stuck during use. Drainage cannot be realized, and it is especially inconvenient for the elderly or children with little strength to use

Embodiment Construction

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The present invention provides a drain valve structure with a small operating force, which includes a valve body 10 and a valve core 20 for controlling the opening and closing of the drain valve. The valve core 20 is movably installed on the valve body 10. The valve At least one rolling element 30 is also provided between the valve core 20 and the valve body 10, and the rolling element 30 is rotatably mounted on one of the valve core 20 and the valve body 10, and is connected with the valve body 10. The valve core 20 is rollingly matched with the...

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 [0001] The invention relates to the technical field of sanitary ware, in particular to a drain valve structure with a small operating force value. Background technique [0002] In the existing water tank drain valve, the valve core moves up and down to open or seal the drain port. There is a guide part inside the drain valve. When the valve core moves up and down, the valve core cooperates with the guide part to make the valve core move up and down. It is more stable and reliable. The existing guide parts are generally guide grooves or guide ribs, and the valve core is correspondingly provided with guide ribs or guide grooves. The valve core and guide parts realize sliding guidance through the guide grooves and guide ribs. Due to the sliding fit, the coefficient of friction between the spool and the guide parts is relatively large, so pressing the button or pulling the wrench to lift the spool requires a large amount of operating force, and the button or wren...
