Abstract
The utility model relates to a plugging device used during fuel gas side pipe maintenance. The plugging device comprises an elastic plugging part, a screw and a limit part, wherein the elastic plugging device is used for preventing fuel gas from being input from a side pipe into a branch pipe, the screw is disposed in the middle area of the elastic plugging part, and the limit part is used for fixing the position of the screw. The plugging device has the advantages that the plugging device can be used for plugging the branch pipe of a user with fuel gas leakage without affecting normal fuel gas use of other users, and no harm the other users can be caused when the plugging device is used during the maintenance for the user with the fuel gas leakage.
Description
Technical field
the utility model relates to a kind of blocking device of using while keeping in repair combustion gas arm.
Background technique
user's combustion gas such as coal gas or rock gas used is to be transported to appointed place by main line, and then the bye-pass that utilization is connected with main line is supplied with user.Pipeline connecting parts wherein adopts tee pipe fitting conventionally, and makes bye-pass and main line on tee pipe fitting perpendicular, and total valve is installed on main line.Bye-pass is the pipeline that combustion gas is provided for multiple users of same unit in building, each user is connected with bye-pass by branch line respectively, if have user branch line used or the valve being arranged on branch line to occur gas leakage problem, not only can pollute surrounding enviroment, and because of also easy firing of combustion gas, there will be inevitable serious accident.For this reason, as long as there is a user that the information of gas leakage is provided, send at once maintenance man to keep in repair gas leakage position for the enterprise of combustion gas.
in the prior art, while keeping in repair with indoor branch line or valve, first the total valve of installing on main line is closed, and then maintenance or replacing branch line and/or valve.Although this kind of maintenance mode can solve gas leakage problem, but the user who only needs repairing knows that main valve is closed, and the user who is not keeped in repair is in the time opening gas valve, because there is no combustion gas output, the user who has in the case can forget the gas lockout valve of opening, and when again main line total valve is opened after maintenance task completes, the whole users that supply with for this bye-pass provide combustion gas, cause the user that opens valve not light because of combustion gas, thereby can cause gas pollution environment and produce the serious accident that is difficult for avoiding.
it is by magnetic seal gland and teflon strip of paper used for sealing that the name of Chinese patent 202852322U notice of authorization is called " a kind of gas pipeline leakage point fast plugging device ", and sealer forms.Magnetic seal gland is wherein for the parts on the outer wall of the gas leakage point of shutoff gas pipe line or container, teflon strip of paper used for sealing is for being embedded in the parts in magnetic seal gland lower surface annular seal groove, and sealer is for the parts on the gas leakage point outer wall of bonding magnetic pressure seal bonnet and gas pipe line or container.Although this kind of blocking device also can shutoff gas pipe line, but because the coal gas in gas pipe line has certain pressure, and utilize teflon strip of paper used for sealing and sealer to be difficult for magnetic seal gland to be fixed on gas pipe line port, so, this kind of blocking device can only shutoff gas pipeline leakage point position, blocking device used when it is not suitable for being applied in maintenance fuel gas pipeline.
Summary of the invention
the purpose of this utility model is to provide the blocking device of using when a kind of mode of utilizing direct shutoff bye-pass solves the maintenance combustion gas arm that user forgets throttle down problem.
the blocking device of using when maintenance combustion gas arm that the utility model proposes comprises for stoping combustion gas be input to the elasticity closeouts in branch line and be arranged on the screw rod in elasticity closeouts central region from bye-pass, and for the bounding means of standing screw position.
described elasticity closeouts is made up of spheroid, and one end of screw rod is fixed in spheroid.Described bounding means comprise plug and be arranged between elasticity closeouts and plug and be enclosed within the pipe fitting on screw rod.Described plug be axially provided with the screw that can be screwed on screw rod.The through hole that is axially provided with the insertion of permission screw rod of described plug.Described screw rod is provided with the nut for fixing plug away from one end of elasticity closeouts.
the blocking device of using when maintenance combustion gas arm that the utility model proposes can be with its shutoff gas leakage user's branch line, normally use combustion gas and do not hinder other users, so, utilize the user that combustion gas is leaked in this kind of blocking device maintenance can not cause damage to other users; Simultaneously, because this blocking device is just made up of elasticity closeouts and screw rod and bounding means, its structure is relatively simple, and fabricating cost is also lower, and maintenance procedure is also simpler.
Brief description of the drawings
the blocking device of using when accompanying drawing 1 is the maintenance combustion gas arm the utility model proposes is arranged on the cross-sectional view of an embodiment on tee pipe fitting;
accompanying drawing 2 is surface structure schematic diagram of Fig. 1 Elastic closeouts and screw rod;
accompanying drawing 3 is surface structure schematic diagram of bounding means in Fig. 1.
Embodiment
referring to Fig. 1 to Fig. 3, an embodiment's of blocking device who uses when these three accompanying drawings provide the maintenance combustion gas arm that the utility model proposes surface structure.This blocking device comprises elasticity closeouts 1 and screw rod 2, and bounding means 3.Elasticity closeouts 1 is wherein the spheroid of being made up of rubber or similar elastic material, between the branch line 4 providing in the present embodiment and bye-pass 5, be to interconnect by tee pipe fitting 6, and make branch line 4 mutually vertical with bye-pass 5, because elasticity closeouts 1 is the parts for shutoff bye-pass 5, so its slightly larger in diameter is in the diameter of tee pipe fitting 6.Screw rod 2 is the parts for delivery of elasticity closeouts 1, and the mode that its one end can be excessively pre-buried is fixed in elasticity closeouts 1, and is provided with outside thread 21 at the other end of screw rod 2, and the nut 22 for limiting elasticity closeouts 1 position is installed on outside thread 21.Bounding means 3 comprise plug 31 and be arranged on elasticity closeouts 1 and plug 31 between and be enclosed within the pipe fitting 32 on screw rod 2, the outer surface of described plug 31 is provided with the outside thread 33 that can be screwed in tee pipe fitting 6, and is provided with the through hole 34 that allows screw rod 2 to insert at the axial middle part of plug 31.
leak in the process at combustion gas position maintenance user, first pipe fitting 32 is enclosed within on screw rod 2, then the through hole of shutoff 31 34 is inserted on screw rod 2, after by tee pipe fitting 6, the pipe fitting on same straight line is removed with bye-pass 5, insert in it taking elasticity closeouts 1 as input end from the opening end of tee pipe fitting 6 rapidly, and then plug 31 is screwed on tee pipe fitting 6, then nut 22 is screwed on screw rod 2, so that elasticity closeouts 1 is fixed.
