Abstract
The present invention provides a safe non-return water-sealed valve which is arranged on an overflow pipe of a clear water pool. The valve is composed of a valve body with a trap and a cover plate with a floating ball. The present invention is characterized in that the floating ball is arranged on one side of a clear water flow channel. The present invention has the characteristics that overflow is smoothly carried out without obstruction, and sewage can be effectively prevented from flowing back, and the anti-pollution performance can not be influenced as the present invention can not be attached by impurities.
Description
The present invention relates to a kind of safety check that draining is flow backwards that prevents that is used on the clear water reserviors spill pipe.This valve is after water level is higher than highest water level in the clear water reserviors, can make water be discharged into drainage pipeline outside the pond rapidly by spill pipe, but when drainage pipeline causes water level to be higher than the clear water reserviors water level because of reasons such as obstructions, can automatically prevent backing up of sewage, and water seal prevents that oxious gas from entering clear water reserviors at ordinary times by valve, to keep the good hygienic state of potable water in the clear water reserviors.
In Drinking Water and process water system, the clear water reserviors important component part that is absolutely necessary is to guarantee pond safety, and clear water reserviors are all installed spill pipe, and the spill pipe outlet is general feeds in the drainage inspection well.If seal apparatus against the current in the air just has the backing up of sewage pond on spill pipe, pollute the danger of Drinking Water or domestic water.The accident of this pollution is a lot of in the practice.
Earlier by non-return water-sealed valve mainly is slightly larger than 1 ball float by the increaser of one section bending and proportion and forms, and when just often, it can make the water overflow in the clear water reserviors and prevent backing up of sewage.But in case there are foreign material to adhere to sphere or dried consolidating in the above, this valve just can not prevent backing up of sewage, still has the contaminated danger of Drinking Water.
Non-return water-sealed valve of the present invention aims to provide a kind of simple and reasonablely, and no-sundries adheres to sealed pipe, influences anti-reverse performance, safe non-return water-sealed valve.
Non-return water-sealed valve of the present invention mainly is made up of valve body, sealing seat, sealed cover and ball float, ball float and cover plate fuse, the component movement black box, when the outside overflow of clear water pool inner water, the ball float cover plate assembly is easy to open because of floating function, make the water overflow without hindrance, when overflow stopped, the ball float cover plate assembly was closed automatically because of its total proportion is slightly larger than 1; When draining was poured in down a chimney, cover plate was pressed on the seal valve seat, can stop refluence effectively.Be positioned at pipeline clear water reserviors one side because of sealing surface and ball float again, do not contact with dirt, thus do not have stop up, the jam phenomenon, so can guarantee safety, make clear water reserviors not be subjected to draining to pour in down a chimney the evil of pollution.
Main feature of the present invention is to have replaced original ball float with ball float and cover plate assemblying body, and makes ball float be positioned at clear water one side forever, does not contact with sewage, is difficult for infringement, makes non-return water-sealed better effects if, and reliable degree improves.
Describe the concrete structure of non-return water-sealed valve of the present invention in detail below in conjunction with accompanying drawing.
Accompanying drawing is the main sectional view of non-return water-sealed valve of the present invention.
With reference to accompanying drawing, valve body 1 constitutes an airtight fluid passage with valve gap 2, seal valve seat 5 valve gaps 2 are pressed on the valve body 1, the pilot hole that ball lever 2 upper ends are passed on the seal valve seat 5 tightly is screwed in cover plate 4, the lower end is connected with ball float 6 and is set on the guide ring 7, guide ring 7 is fixed on the valve body 1, and maintenance atmospheric valve 8 also is housed on the valve body 1.
In actual motion, when clear water reserviors produced overflow, overflow water at first entered in this valve body 1, and made ball float 6 produce buoyancy, by ball float 3 cover plate 2 impacting forces was reduced, and when flood level was higher than cover plate 4, water just can enter sewerage by valve cover smoothly.When clear water reserviors stop overflow, and when water level was lower than cover plate 4 in the spill pipe, overflow stopped, and cover plate 4 also covers tightly on seal valve seat 5.In the time of in sewage enters valve gap, cover plate 4 is in closed condition, and then sewage can not enter valve body.Thereby can prevent backing up of sewage effectively, the protection clear water reserviors are not contaminated.And; in the time of above foreign material in the sewage stick to cover plate 4; still do not influence the sealability of its lower surface; and the clear water that the valve body curved section retains; the oxious gas that can intercept drainage pipe enters clear water reserviors, if spill pipe not overflow for a long time, the water seal evaporate to dryness; cover plate 4 can intercept oxious gas equally, and the health of protection clear water reserviors is good.
Claims (1)
1. non-return water-sealed valve of forming by valve body 1, valve gap 2, seal valve seat 5 and cover plate 4, ball float 6, it is characterized in that valve gap 2 is pressed on seal valve seat 5 on the valve body 1 that has trap, in seal valve seat 5 on valve insertion be divided into mutually isolated two-part in 1 spool by cover plate 4 lids are tight by ball lever 3 and cover plate 4, ball float 6 ratio of components are great, and the major component of ball float 6 and ball lever 3 all is positioned at a part, be the clear water runner section, and ball lever 3 pass the guide ring 7 that is fixed on the valve body 1 and the pilot hole on the seal valve seat respectively.
