Abstract

The utility model discloses a water-stop mandrel, belonging to the technical field of the manufacturing of a water control switch of a faucet. The water-stop mandrel adopts the following structure that the bottom end of a water stop seat is additionally provided with a non-return gasket; the water flow enters from the inlet of a ferrule, passes through a through port that a ceramic water stop moving plate and a ceramic water stop static plate are matched with each other and flows out of the outlet of the side wall of the water stop seat; when the water pressure at the hot side is higher than the water pressure at the cold side in a cold and hot flow device, the hot water can flows in from the side wall of the water stop seat; the water pressure can be used for sealing the non-return gasket and the water inlet of the copper ferrule, and the hot water can not flow out from the water inlet of the ferrule, so as to achieve the non-return aim.

Description

Novel sealing mandrel structure

Technical field

The utility model discloses a kind of sealing mandrel, belongs to water tap control water switch manufacturing technology field, especially relates to a kind of sealing mandrel with the backflow functionality of preventing.

Background technique

Common practise, mandrel is one of parts that influence water tap quality most critical, it is several that the mandrel of water tap generally can be rubber core, ceramic valve core and stainless steel spool etc., and the water tap of use rubber core mostly is the cast iron bibcock of spiral unlatching, has been eliminated substantially now; The ceramic valve core water tap occurred in recent years, and quality is better, and was commonplace now; The stainless steel spool just occurs recently, is more suitable for the area of water quality inferiority.

Yet, present mandrel is not generally prevented the function of backflow, and non-return is meant and relies on current itself to flow and automatic open and close flap in the pipeline, is used for the medium one-way flow, promptly only allow medium to flow to a direction, to prevent the refluence phenomenon,, take place and may security incident will take place in case reflux especially for the thermal medium in the water pipe, generation for fear of above-mentioned situation, usually will add safety check again on pipeline, adopt above-mentioned setting, promptly having prolonged the duration has increased installation cost again.

Summary of the invention

At the deficiency of existing mandrel non-return technology, the utility model provides a kind of sealing rational in infrastructure, that have check function new core barrel structure.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of novel sealing mandrel structure comprises mandrel component, and wherein: also comprise the non-return pad, the bottom inlet place that this non-return pad is arranged at mandrel component is used to prevent the medium back flow of flow channel in the mandrel component.

Further, described mandrel component is mainly by the sealing seat, packing ring, the sealing bar, seal ring, pottery sealing moving plate, pottery sealing still and lasso are formed, seal ring is placed in the groove of sealing bar, packing ring, the sealing bar, pottery sealing moving plate, pottery sealing still is assembled in the center hole of sealing seat successively, sealing seat bottom is by the lasso shutoff, sealing seat sidewall is provided with water outlet, with ceramic sealing moving plate, the lasso of pottery sealing still and sealing seat bottom is gone into interruption-forming one flow channel, sealing bar bottom is the struck side, when clockwise or when being rotated counterclockwise the sealing bar, the sealing bar drives ceramic moving plate and rotates the port closure that matches with ceramic still or open, and promptly realizes the Push And Release of mandrel.

Further, described non-return pad, the T-shaped shape in its cross section, described lasso are copper sleeve ring or plastic ferrule or alloy lasso, the silicagel pad of the embedded central through bore of lasso, and above-mentioned non-return pad is arranged at copper sleeve ring and silicagel pad central hole.

Further, establish a bloop on the described ceramic sealing moving plate, the struck side of sealing bar is passed bloop and is plugged on the ceramic sealing moving plate.

Further, a U type jump ring is overlapped at described sealing seat top, the right switch dissected valley in the cold limit of sealing seat, and hot limit left-handed opening does not have ditch.

The utility model adopts said structure, the bottom of sealing seat adds a non-return pad, when current enter from the lasso inlet, port through ceramic sealing moving plate and ceramic sealing still match flows out from the sidewall outlet of sealing seat, when hot limit hydraulic pressure in the cold and hot water plant during greater than cold limit hydraulic pressure, hot water flows into from the sidewall of sealing seat, hydraulic pressure seals up non-return pad and copper sleeve ring water intake, and hot water can't be gone out from the lasso water intake, thereby plays the purpose of non-return.

The utlity model has following useful effect:

1, the utlity model has the non-return effect, make this mandrel that the Security of the incident of being scalded can not take place;

2, not be used in installation check vavle device in the pipeline so cost is low.
