Abstract
A kind of blast pipe plugging device, it is mainly：The external diameter for blocking disk is corresponding with the internal diameter of exhaust passage, in disk towards being provided with the end face opposite with exhaust passage with it with center line and the stud that is vertically connected, the stud free end is quadrangular, inside set inner bolt hole, the closure stud is meshed with the center screw of circular groove shape carcass bottom land, and the quadrangular being located at through the center screw outside carcass is connected with handle, the carcass is non-enclosed circular groove, gap is provided with i.e. from circular groove opening to central through hole, respectively set that an axis is vertical with gap and the through hole of both coaxial lines on the external groove sidevall of gap both sides, a connecting bolt is set in the through hole of gap both sides.The utility model can be simply and rapidly connected on heat examination line gas exhaust piping, and it is implemented to block；Prevented due to exhaust passage closure come off, tail gas leakage caused by electronic controlled diesel wire harness roastingization cause fail the problem of；Reduce and waste, reduce production cost.
Description
Technical field the utility model is related to a kind of accessory for manufacturing diesel oil machine testing.
Each side there is an exhaust passage inside the equipment of background technology detection small displacement diesel engine test line, with
Adapt to the needs of different type of machines exhaust emission testing.But the two exhaust passages are connections, and the only company of need during engine test
It is connected on a passage, another standby exhaust passage is then blocked with rubber frock, prevents motor exhaust from this leakage.Can
It is during the experiment of engine, because rubber is thermo-labile, softening transform, along with having certain pressure in passage, so rubber
Glue frock is often fallen off, and causes 400-500 DEG C or so of motor exhaust to be leaked out from the side exhaust pipe, by electronic controlled diesel
Wire harness roastingization failure, cause the improper damage of electronic controlled diesel wire harness, never solution.
Content of the invention the purpose of this utility model is to provide one kind and standby exhaust passage is simple, quick, effective can sealed
It is stifled, the blast pipe plugging device for preventing motor exhaust from being leaked from this.
The utility model mainly includes：Closure, carcass handle and fastening bolt.Wherein, closure is by disk and stud group
Into, the external diameter of the disk is corresponding with the internal diameter of exhaust passage, and best disk outer peripheral face is in truncated cone shape, and one part is positioned at row
In gas passage, another part is located at outside exhaust passage, you can it is less than exhaust passage internal diameter into the minor diameter in exhaust passage, and
Major diameter outside exhaust passage is more than exhaust passage internal diameter.Disk towards be provided with the end face opposite with exhaust passage with
, with center line and the stud that is vertically connected, the stud free end is quadrangular, is set in quadrangular with it with center line for it
Screw.The closure stud is meshed with the center screw of circular groove shape carcass bottom land, and is located at through the center screw outside carcass
Quadrangular it is corresponding with handle center through hole, the inner bolt hole of screw and quadrangular through handle center's through hole is threadedly coupled.
Best handle uses non-metallic material, prevents from scalding one's hand.The carcass is non-enclosed circular groove, i.e., from circular groove opening to central through hole
Provided with gap, respectively set that an axis is vertical with gap and the through hole of both coaxial lines on the external groove sidevall of gap both sides, in gap
A connecting bolt is set in the through hole of both sides, makes the carcass into swelled structure.
The course of work of the present utility model approximately as：Envelope will be blocked in before testing in the opening of blast pipe, then will
The stud of closure is threadedly coupled with carcass, and at the same time carcass sleeve is on blast pipe, and then fastening bolt, makes carcass firm
Ground is enclosed on blast pipe, and the tightness degree combined by rotary handle adjustment closure with blast pipe, while is also closure positioning.
The utility model has the following advantages that compared with prior art：
1st, it can simply and rapidly be connected on heat examination line gas exhaust piping, it is implemented to block；
2nd, prevented because exhaust passage closure comes off, electronic controlled diesel wire harness roastingization caused by tail gas leakage causes to lose
The problem of effect；
3rd, reduce and waste, reduce production cost；
4th, hidden fire-fighting danger is thoroughly eliminated；
5th, it can not only apply in heat examination line, but also can be applicable to service station.
Brief description of the drawings
Fig. 1 is the utility model use state main view section simplified schematic diagram.
Fig. 2 is the main view schematic diagram of carcass in Fig. 1.
Embodiment
In the blast pipe plugging device main view section simplified schematic diagram shown in Fig. 1, closure 1 is made up of disk and stud
, the external diameter of the disk is corresponding with the internal diameter of exhaust passage, and disk outer peripheral face is in truncated cone shape, and one part is located at exhaust passage
Interior, another part is located at outside exhaust passage, you can it is less than exhaust passage internal diameter into the minor diameter in exhaust passage, and positioned at row
Major diameter outside gas passage is more than exhaust passage internal diameter.It is provided with the disk direction end face opposite with exhaust passage with it with
Heart line and the stud being vertically connected, the stud free end are quadrangular, and inner bolt hole with center line with it is set in quadrangular.Should
Closure stud is meshed with the center screw of the bottom land of circular groove shape carcass 2, and is located at four ribs outside carcass through the center screw
Post is corresponding with the heart through hole of handle 3, and the inner bolt hole of screw and quadrangular through wood handle central through hole is threadedly coupled.It is described
Carcass is non-enclosed circular groove, as shown in Fig. 2 being provided with gap, the water jacket in gap both sides from circular groove opening to central through hole
Respectively set that an axis is vertical with gap and the through hole of both coaxial lines on wall, a connecting bolt is set in the through hole of gap both sides
4, make the carcass into swelled structure.
