Abstract
The utility model aims at reducing the operating steps of industrial blowing/sweeping and sending alarms for gas diffusion caused by unreliable connection of valves during operation. In order to realize the above purposes, the utility model adopts the technical scheme of providing a three-way combination valve which can reduce the steps of blowing/sweeping operation and can send alarms for unreliable connection of the valves in a whistling manner. The three-way combination valve comprises three valves, a tee joint, a connecting ring and a whistle, wherein the three valves are respectively connected with three arms of the tee joint, a material medium pipeline and a blowing/sweeping medium pipeline are respectively connected with the three-way combination valve through one valve, and one of the three valves is connected with the connecting ring and the whistle. When in whistling operation, the valve connected with the whistle is closed, and blind blocking is not needed; at ordinary times, the valve connected with the whistle is opened; if the valve of the medium pipeline is not tightly closed, whistling alarms can be sent out; therefore, a user can timely detect and handle the problems.
Description
[technical field]
The utility model relates to a kind of combination brake switch and proporting, is specifically related to medium and purges pipeline threeway combination brake switch and proporting.
[background technique]
All deposited flammable, can be quick-fried, poisonous, the equipment and the pipeline of harmful material, before maintenance or getting angry, must drain material, purge, displacement is clean, it is qualified to analyze.Must formulate purging, replacement scenario before the displacement, the sweeping process figure that should draw in case of necessity prevents to omit, and stops the dead angle.With production, bunkerage joint, except that closing dead valve, must block up tight blind plate, hang up sign, isolated material source.The purpose that purges is: 1 holds the dust that may have the meeting polluted product in the antenatal pipeline removes by purging; The air that retains in 2 pipelines may react with working gas influences quality of product; The fugitive constituent of 3 working gass or working liquid body and air form explosive mixture.In a word, the purpose of purging is for cleanser conduit or replaces, to eliminate the factor that may influence quality of product and production safety.
U.S. Hanover's valve group is a famous international professional valve company an of family, production has various nitrogen cut-off valves, the nitrogen-sealed valve, nitrogen purge valve, the high pressure nitrogen that is used for oxygen pipeline, coal slurry pipeline purges and the working pressure height, pressure reduction is big, and the seal request height has the occasion of the requirement of switching speed.But the threeway combination brake switch and proporting especially has the purging that blows whistle and yet there are no report with the threeway combination brake switch and proporting.
[summary of the invention]
The mode that the installation of industry purging pipeline generally adopts double valve to add stifled blind plate connects, in use need to tear open stifled blind plate, increase the step of operation, if installing, blind plate do not reach the leakage that requirement is easy to cause coal gas simultaneously, the Placement of double valve does not connect because valve is not reliable the cut-out, can cause the gas blowby between the valve, bring hidden danger to safety.
The purpose of this utility model is: reduce the job step that industry purges, valve in the operation is connected unreliable caused gas-blowing phenomenon report to the police.
For achieving the above object, the technological scheme taked of the utility model is: provide a kind of reduce to purge job step and can connect unreliable phenomenon to valve carry out the threeway combination brake switch and proporting that whistle is reported to the police.
Described threeway combination brake switch and proporting comprises three valves, a threeway, and three valves link to each other with three arms of threeway respectively, and the material medium pipeline links to each other with the threeway combination brake switch and proporting by a valve respectively with the blowing medium pipeline; Comprise connecting ring, blow whistle that a valve and connecting ring are arranged, it is continuous to blow whistle; With the valve closing that blows whistle and link to each other, needn't use blind plugging when blowing a whistle operation; With the valve open that blows whistle and link to each other,, can send whistle at ordinary times, can in time pinpoint the problems and handle if the medium pipeline valve closing is not tight.The use of threeway combination brake switch and proporting, stopped present purging operation and torn the loaded down with trivial details work of stifled blind plate open, operation and maintenance simultaneously are simple, in use can in time find valve gas leakage problem, avoid single valve seal sternly not cause the pipeline gas-blowing phenomenon, increased on-the-spot Security.
The utility model advantage is:
1. effectively reduce the job step that industry purges.
2. effectively prevent the gas blowby of material medium and blowing medium.
3. if problems with valves causes medium to reveal, send whistle by blowing whistle, can in time find and handle.
[description of drawings]
Fig. 1 is a threeway combination brake switch and proporting structural representation.
Fig. 2 is that the threeway combination brake switch and proporting purges the operation connection diagram.
[embodiment]
Below in conjunction with embodiment and with reference to accompanying drawing the utility model is further described.
The reference character and the constituent element that relate in the accompanying drawing 1 are as follows:
1. threeway 2. purges valve
3. material valve 4. diffuses valve
5. connecting ring 6. blows whistle
Please referring to Fig. 1, Fig. 1 is the utility model threeway combination brake switch and proporting structural representation, and described threeway combination brake switch and proporting comprises threeway 1, purges valve 2, material valve 3, diffuses valve 4, connecting ring 5, blows whistle 6.Described purging valve 2, material valve 3, diffuse valve 4 and link to each other with three arms of threeway 1 respectively, connecting ring 5, blow whistle 6 with diffuse valve 4 and link to each other.
Please referring to Fig. 2, Fig. 2 is that the utility model threeway combination brake switch and proporting purges the operation connection diagram, material medium pipeline 8 links to each other with material valve 3, blowing medium pipeline 7 links to each other with purging valve 2, in normal operation, purging valve 2 and material valve 3 closes, diffusing valve 4 opens, purge between valve 2 and the material valve 3 space by diffuse valve 4, blowing whistle 6 links to each other with atmosphere, when any one valve takes place to leak in purging valve 2 and material valve 3, blow whistle and 6 will send warning, can in time find and handle problems; When needs diffuse blowing medium or material medium, only need to remove blow whistle 6, open its corresponding valve; , only need close and diffuse valve 6 when wherein a kind of medium purges another kind of medium at needs, beat then and purge valve 2 and material valve 3 gets final product.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
