Abstract
The utility model relates to a diaphragm valve with a diaphragm failure detection device, which comprises a valve body, a valve cover and a diaphragm arranged between the valve body and the valve cover, wherein a through hole is arranged at the lowest position close to the diaphragm on the side wall of the valve cover. A detection device is arranged in the through hole, the detection device comprises a transparent cover fixedly connected with the valve cover and reagent paper positioned in an inner cavity of the transparent cover, and a sealing ring is arranged between the transparent cover and the valve cover. The utility model has the advantages and positive effects of simple structure, safety, low reforming cost, convenient use and easy maintenance and provides effective approaches for the safe operation and the timely maintenance. Funds can be obviously saved, and economic benefits can be obviously improved.
Description
Technical field
The utility model relates to membrane valve, particularly a kind of membrane valve with diaphragm failure detection device.
Background technique
Existing chemical industry membrane valve has the strong characteristics of corrosion resistance, but also needs further perfect at secure context.For example: carrying with chemical pump when having the liquid of chemical industry particularity, owing to have plenty of deep-etching solution, having plenty of and contain solution toxic but that have high economic value, be difficult for discovering under the situation people, the diaphragm inefficacy of membrane valve can cause occurring internal leak.The seepage harm that the inefficacy of diaphragm valve causes, gently then liquid is carried in the befouling environment loss; Heavy then because of chemical industry with the particularity of carrying liquid, nothing is discovered under, can damage or corrode parts, the crisis that causes other degree of depth is the thing of normal generation.So far, related domain does not still have good diaphragm failure detection device, causes diaphragm valve after the long operating time, and diaphragm lost efficacy and was difficult for discovering, and caused the loss and the harm of secure context, simultaneously, did not also meet the requirement of plant maintenance.
The model utility content
The purpose of this utility model provides a kind of membrane valve with diaphragm failure detection device of simple in structure, safe and reliable, easy to use, easy maintenance.
For achieving the above object, the utlity model has the membrane valve of diaphragm failure detection device, comprise valve body, valve gap and be installed in described valve body and described valve gap between diaphragm, extreme lower position close with diaphragm on described valve gap sidewall has through hole, detection device is installed in through hole, described detection device comprises the transparent cover of fixedlying connected with described valve gap and is arranged in the reagent paper of described transparent cover inner chamber, is provided with seal ring between described transparent cover and the described valve gap.
The utlity model has the membrane valve of diaphragm failure detection device, the surface of wherein said transparent cover is the convex lens face that the imaging amplification is arranged.
The utlity model has the membrane valve of diaphragm failure detection device, wherein said transparent cover is a plexiglass tent.
The advantage and the good effect that the utlity model has the membrane valve of diaphragm failure detection device are simple in structure, safe and reliable, its improvement expenses is low, easy to use, safeguard easily, provide effective means to solving safe operation and in time safeguarding, and economized on the use of funds significantly and increase economic efficiency.
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that the purpose of this utility model, feature and advantage are had deep understanding.
Description of drawings
Fig. 1 is the plan view that the utlity model has the membrane valve of diaphragm failure detection device;
Fig. 2 is the partial sectional view of diaphragm failure detection device in the utility model membrane valve.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, the membrane valve that the utility model provides with diaphragm failure detection device, comprise valve body 1, valve gap 2 and be installed in valve body 1 and valve gap 2 between diaphragm 3, have through hole 9 in valve gap 2 sidewalls and diaphragm 3 close extreme lower positions, detection device 4 is installed in through hole 9.With reference to Fig. 2, the reagent paper 7 that detection device 4 comprises the transparent cover 6 of fixedlying connected with valve gap 2 and is arranged in transparent cover 6 inner chambers, transparent cover 6 is installed in the through hole by screw thread, is provided with seal ring 8 between transparent cover 6 and the valve gap 2.
In the embodiment of the utility model membrane valve, transparent cover 6 is a plexiglass tent, and the surface of cover is the convex lens face that the imaging amplification is arranged, in order to observation.
Using effect below in conjunction with description of drawings the utility model membrane valve.Diaphragm 3 is in the motion of long-term open and close, in case because of assembling the seepage that diaphragm bad or that the diaphragm material ageing is brought lost efficacy and causes, effusion will inevitably take place ooze out from the opposite side of diaphragm, and assemble along the lowest part of valve gap 2.In case diaphragm 3 lost efficacy, delivered solution begins seepage, is in the detection device 4 that is installed on the extreme lower position, and reagent wherein absorbs the conveying liquid that exosmoses with paper 7 the earliest by through hole, makes reagent paper produce chemical reaction and variable color.At this moment, directly perceived outside transparent plexiglass tent 6 as seen prompting should be disposed immediately, behind maintenance or the replacing diaphragm, will effectively realize the good management of equipment in time.Because seepage is undiscovered for a long time after taking place usually, will cause the corrosion and damage of whole membrane valve, to avoid serious corrosion so in time find seepage, usually only need timely replacing diaphragm and avoid the discarded of whole valve body, this will help reducing the loss of financial resource and material resource greatly, improve economic benefit of enterprises.
The membrane valve with diaphragm failure detection device that the utility model provides is simple in structure, safe and reliable, and its improvement expenses is low, and easy to use and easy maintenance provides effective means to solving safe operation and in time safeguarding.
