Abstract
The utility model relates to a vacuum inhibitor which comprises an outer cylinder and a cover, wherein the outer cylinder is provided with an inner sealing layer and an outer sealing layer; the outer sealing layer is provided with a sealing valve which is connected with a float through a lengthening rod; and the inner sealing layer is provided with a sealing valve which is connected with a float through a lengthening rod. The utility model has the advantages that by adopting the two sealing layers, after the first sealing fails, the second sealing works; the vacuum inhibitor has the warning function, the service life of sealing is prolonged, and the sealing property is reliable.
Description
Technical field
The utility model relates to a kind of water supply facilities parts, especially a kind of vacuum suppresser.
Background technology
Vacuum suppresser is a kind of vacuum automatic eliminator, is mainly used in municipal water supply equipment.Mainly there is following problem in the vacuum suppresser of using on the existing market: one, individual layer sealing, and the whole device of seal failure just can't use, and causes the user also not find just have a large amount of water to flow out, and causes surrounding enviroment are destroyed; Two, water and sealing surface contact, and easily form incrustation scale on sealing surface, make seal failure for a long time easily; Three, directly seal with float, float is out of shape after being subjected to hydraulic pressure for a long time, causes and leaks; Four, when tap water pressure is low, leak easily, equipment is low at tap water pressure mostly is to occur leaking, and recovers normal after pressure uprises again; Five, adopt the bottom suction and discharge, when vacuum suppresser is worked,, when suction and discharge, vibe easily, produce noise pollution because stack is long; Six, suction and discharge are young can't install filter, and insect, dust etc. easily enters when vacuum suppresser is worked causes secondary pollution in the water.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of vacuum suppresser of good seal performance is provided.
The utility model solves the technical scheme that its technical problem adopts: this vacuum suppresser, comprise urceolus and lid, urceolus is provided with inside and outside two sealants, and wherein outer sealing layers is provided with the seal valve that connects float by extension bar, and inner sealant layer is provided with the seal valve that connects float by linkage component.
As preferably, described seal valve comprises by cooperating at the bottom of the valve that can form sealing effectiveness and valve gap, and spacing valve seat, and wherein valve gap is loaded on extension bar or the linkage component.Described valve gap is overshooting shape ringwise, has improved the reliability of sealing, has solved the problem that the long-term compressive deformation of float is brought simultaneously.
As preferably, the seal valve of described inner sealant layer top is provided with the tongue tube that can send signal after the conducting, after the first floor seal failure, when second layer sealing enters duty, in time sends signal.
As preferably, form downward annular suction and exhaust ports between described lid and the urceolus.Increased effective suction and discharge bore, the path of having shortened suction and discharge, noiselessness produces at work, prevents that effectively rainwater from entering
As preferably, described suction and exhaust ports place is provided with strainer.Prevent that effectively insect, dust etc. from entering.
The effect that the utility model is useful is: one, adopt two-layer hermetically-sealed construction, after the first floor seal failure, second layer sealing enters duty, sends signal simultaneously, and the user in time recognizes equipment working state, and can carry out maintenance process to it; Two, before water does not contact valve seat, valve gap with at the bottom of the valve contacts the formation sealing, therefore sealing surface is not contacted with water, increases to seal application life; Three, the first floor sealing is to use extension bar between float and the seal valve, utilize the hydraulic pressure characteristic, float is passed to valve gap at water-bed pressurized by extension bar, the sealing surface pressurized is increased, guaranteed when tap water pressure is low, also finely to seal, second layer sealing utilizes lever principle with the stressed further increasing of float, increases the stressed of sealing surface, and sealing performance is just added reliably.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Description of reference numerals: float 1, extension bar 2, valve gap 3, at the bottom of the valve 4, valve seat 5, urceolus 6, strainer 7, lid 8, tongue tube 9, linkage component 10, suction and exhaust ports 11.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
With reference to accompanying drawing 1: a kind of vacuum suppresser, comprise the lid 8 that urceolus 6 and top thereof are provided with, form downward annular suction and exhaust ports 11 between lid 8 and the urceolus 6, suction and exhaust ports 11 places are provided with strainer 7.Urceolus 6 is provided with inside and outside two sealants, wherein outer sealing layers is provided with the seal valve that connects float 1 by extension bar 2, inner sealant layer is provided with the seal valve that connects float 1 by linkage component 10, seal valve comprises by at the bottom of the valve that cooperate to form sealing effectiveness 4 and valve gap 3, and spacing valve seat 5, wherein valve gap 3 is loaded on extension bar 2 or the linkage component 10.
During use, when water level rose, the float 1 that the external seal valve connects rose, extension bar 2 with top on the valve gap 3 with at the bottom of the valve 4 form and seal.When outer sealing layers lost efficacy, when water enters inside,,,, send signal and show that the first floor sealant lost efficacy simultaneously with tongue tube 9 connections on top by the reinforcing formation sealing of 10 pairs of valve gaps of bar linkage structure with float 1 pop-up that interior seal valve connects.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
