Abstract
The utility model discloses a device with a gas replacing and bleeding valve, which comprises a short pipe, a screw rod hand wheel, a screw rod, a copper pipe, a bladder and a nitrogen valve, wherein the lower end of the short pipe is connected with the bleeding valve through a flange, the upper part of the short pipe is fixedly connected with the screw rod hand wheel, the screw rod is matched with the screw rod hand wheel through screw threads and extends into the short pipe, the inside of the screw rod is hollow, the lower part of the screw rod is fixedly connected with the bladder, the copper pipe passes through the screw rod, the upper part of the copper pipe is connected with the nitrogen valve, and the lower part of the copper pipe is communicated with the bladder. Under the condition of the normal operation of a gas pipe network, a bleeding pipe arranged at the upper part of a bleeding valve to be replaced is firstly dismounted, and then, the device is arranged on a valve of the bleeding valve to be replaced through a flange, so a novel bleeding valve is replaced. The device has the advantages that the valve replacement under the condition of the normal work of the gas pipe network is realized, and no influence is caused on the production of manufacturing plants under the condition of operation safety protection, so the economic loss is reduced.
Description
Technical field
The utility model relates to when the gaspipe network operate as normal diffusing the device that valve is changed.
Background technology
In steel production enterprise, gaspipe network diffuse valve work a period of time just need to change, otherwise valve may ftracture, and causes factory to be forced to stop production.If directly valve is changed during the gaspipe network operate as normal then security incident can be occurred, so normally used method is to reduce the pressure of gaspipe network when changing valve.In case the gaspipe network step-down will cause factory to be forced to stop production, and brings economic loss to factory.
The utility model content
Problem to be solved in the utility model provides a kind ofly changes the device diffuse valve with coal gas, makes when the gaspipe network operate as normal and can change the valve that diffuses on the pipeline, when guaranteeing handling safety, can guarantee that again factory can produce to direct motion.
The utility model band coal gas is changed the device that diffuses valve, and it is characterized in that: it comprises short tube, screw mandrel handwheel, screw mandrel, copper pipe, bladders, nitrogen valve; The lower end of short tube by flange with diffuse valve and link to each other the fixedly connected screw mandrel handwheel in its top; Screw mandrel matches to merge by screw thread and screw mandrel handwheel and extend in the short tube screw mandrel boring, the fixedly connected bladders in its underpart; Copper pipe passes from screw mandrel, and its top connects nitrogen valve, and the bottom communicates with bladders.
Under the situation of the normal operation of gaspipe network, the exhaust stack that diffuses valve top that at first will need to change is removed, then the utility model device is installed in diffusing on the valve valve of need changing by flange, then open and diffuse valve, bladders is sent into the bottom of diffusing valve insertion, by nitrogen valve nitrogen is charged into bladders, block coal gas after bladders is expanded, remove short tube and the old valve that diffuses that more renews behind the valve that diffuses; After changing end, short tube is installed once more, nitrogen in the bladders is bled off, bladders is retracted in the short tube; Close newly change diffuse the valve valve, remove the short tube that diffuses on the valve, screw mandrel, screw mandrel handwheel, bladders after, with exhaust stack be reinstalled in changed diffuse valve top.
The utility model device has been realized under the situation of coal gas webmaster operate as normal valve being changed, and the production to factory under the situation of protection handling safety does not impact, thereby has reduced economic loss.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is a kind of changes the device that diffuses valve with coal gas, and it is characterized in that: it comprises short tube 3, screw mandrel handwheel, screw mandrel 6, copper pipe 7, bladders 1, nitrogen valve 8; The lower end of short tube 3 by flange 2 with diffuse valve 9 and link to each other the fixedly connected screw mandrel handwheel in its top; Screw mandrel 6 matches to merge by screw thread and screw mandrel handwheel and extend in the short tube 3 screw mandrel 6 borings, the fixedly connected bladders 1 in its underpart; Copper pipe 7 passes from screw mandrel 6, and its top connects nitrogen valve 8, and the bottom communicates with bladders 1.
Wherein, the screw mandrel handwheel comprises fixed head 4 and terminal pad 5, and fixed head 4 is fixed on the short tube 3, and terminal pad 5 is contained in the hole of fixed head 4, and its center has screwed hole.
Under the situation of the normal operation of gaspipe network, the detailed process of utilizing the online replacing of the utility model to diffuse valve is: 1, remove the exhaust stack that diffuses valve top that needs replacing; 2, short tube is installed and has been linked thereon screw mandrel, screw mandrel handwheel, bladders diffusing on the valve by flange; 3, open the valve that diffuses valve, rotary screw makes bladders to the cavity of resorption that diffuses valve; 4, open nitrogen valve, inflate to bladders, after blocking coal gas after the bladders expansion, close nitrogen valve by copper pipe; 5, unscrew the screw mandrel handwheel, make and diffuse coal gas discharge residual in the valve; 6, after coal gas is discharged, remove short tube and diffuse valve; What 7, more renew diffuses valve; 8, short tube is installed once more; 9, the nitrogen in the bladders is discharged; 10, rotary screw makes bladders to short tube; 11, close and newly change valve, unscrew the screw mandrel handwheel, make and diffuse coal gas residual in the valve and discharge and open; 12, remove short tube, screw mandrel, screw mandrel handwheel, the bladders that diffuses on the valve; 13, exhaust stack is reinstalled in changed diffuse valve top.
The utility model device can be changed valve under the situation of coal gas webmaster operate as normal, and the production to factory under the situation of protection handling safety does not impact.
