Abstract
The utility model relates to an integral rubber filling valve core of a tap, which is composed of a rubber pad and a locating rubber post which are filled with rubber into a whole. The rubber pad is in the shape of a circle, and the bottom of the rubber pad is provided with a lug boss, the locating rubber post is positioned on the upper part of the middle of the rubber pad and is vertical to the rubber pad, and the rubber pad and the locating rubber post are provided with hollow copper skeletons. The utility model has the advantages of simple structure, reliable seal, long service life and convenient manufacture. The locating rubber post and a handle threaded rod of the tap are in flexible contact, and the sealing surface can be prevented from being damaged effectively because of over pressure. The falling of the 'skin line' can be avoided by the utility model, the lug boss at the bottom of the rubber pad has the functions of pressure reduction and flow guiding, and the leakage caused by the deflective rubber pad can be prevented. Therefore, the utility model is especially suitable for the valve core of the tap.
Description
The utility model relates to a kind of water nozzle spool.
Water valve is commonly called as water and chews, and is the great parts of consumption in the city tap-water system, plays crucial effect for water supply and using water wisely.Present widely used water nozzle mainly is made of valve seat, spool and handle, and spool is worked in coordination with valve seat runner and handle screw respectively, can make valve core sealed cover with valve seat runner opening and closing of fault when turning handle, thereby realizes the switch of water nozzle.Spool of the prior art mainly is made of round iron sheet and rubber pad (being commonly called as " skin money "), and iron plate central authorities top riveted is useful on the location copper post of working in coordination with handle screw.Rubber pad is circular, be fixed on the bottom of iron plate and work in coordination with the valve seat runner, the water nozzle spool of said structure, because " skin money " is thinner, between copper post and the handle screw is again rigid the contact, so " skin money " be easy to be pressed partially, pressure " extremely ", even crushed and come off, its result will make poorly sealed close and cause leakage.
The purpose of this utility model promptly is the improvement in addition suitable to the structure of water nozzle spool, pressed partially, presses " extremely ", crushes or come off to avoid " skin money ", thus the sealing effect of assurance spool.
To achieve these goals, the utility model utilizes hollow copper skeleton that the whole injecting glue of spool rubber cushion and positioning rubber column is become a kind of whole glue nozzle valve core.Whole injecting glue spool has not only increased the thickness of seal rubber pad greatly, and make positioning rubber column and contacting of handle screw become flexible contact, therefore can avoid " skin money " to be pressed partially, press " extremely ", crush or come off effectively, thereby guarantee the sealability of spool.Copper skeleton can guarantee the rigidity of whole injecting glue spool.Be described in further detail below in conjunction with the technical characteristics of specific embodiment the whole glue nozzle valve core of the utility model.
Accompanying drawing 1 is the structural representation of the whole glue nozzle valve core of the utility model.
With reference to the accompanying drawings 1, the whole glue nozzle valve core of the utility model is mainly formed by rubber cushion and the whole injecting glue of positioning rubber column.Rubber cushion 1 is circular, and its bottom has a boss 2, and positioning rubber column 3 is positioned at the top of rubber cushion 1 central authorities and vertical with rubber cushion 1.Have a hollow copper skeleton 4 in rubber cushion 1 and the positioning rubber column 3.
The utility model is simple in structure, and sealing is reliable, long service life order convenient processing and manufacture.Whole injecting glue spool can be stopped " skin money " and come off; The boss of rubber cushion bottom has decompression and guide functions, can prevent that rubber cushion from being pressed partially and causing leakage; Positioning rubber column and handle screw contact for flexible, can effectively avoid the sealing surface pressurized excessive and damage.Therefore, the utility model is particularly suitable for as the water nozzle spool.
Claims (1)
