Description
Technical field
The utility model relates to a kind of device of gas heater, the pressure testing device of especially a kind of firing chamber aqueduct.
Background technology
Currently available technology, a kind of pressure testing device of firing chamber aqueduct of gas heater, comprises plug and high-pressure pipe, venthole plug having air admission hole and be connected with air admission hole; High-pressure pipe is connected with air admission hole to be connected.Existing problems are: use inconvenient, work efficiency is low, easily leaks gas.
Utility model content
The purpose of this utility model is: the pressure testing device providing a kind of firing chamber aqueduct of gas heater, and it has easy to operate, the feature that work efficiency is high, and accurately and reliably.
The utility model is achieved in that a kind of pressure testing device of firing chamber aqueduct of gas heater, comprises plug and high-pressure pipe, venthole plug having air admission hole and be connected with air admission hole; High-pressure pipe is connected with air admission hole to be connected; Its special character is: also comprise a cylinder and pedestal,
Described pedestal hollow has upper and lower opening, an end plate of pedestal has passing hole or passing draw-in groove groove, another end plate having upper shed of piston rod,
The cylinder barrel of cylinder is fixedly connected with the end plate of pedestal, and piston rod is slidably matched with through hole or through groove; Described plug arranges in pedestal, and plug is fixedly connected with piston rod, and point-blank, venthole is relative with draw-in groove for the axis of venthole and the axis of piston rod.
The pressure testing device of the firing chamber aqueduct of described a kind of gas heater, its special character is: there is toroidal cavity the outlet side of described plug around venthole.
The pressure testing device of the firing chamber aqueduct of described a kind of gas heater, its special character is: the axes normal described plug having air admission hole and venthole.
The pressure testing device of the firing chamber aqueduct of a kind of gas heater of the utility model, owing to adopting such structure, during use, the flange of aqueduct water inlet end puts into pedestal, and the end plate of flange and pedestal is fitted, and aqueduct is chimeric with draw-in groove; Then cylinder operation, piston rod stretches out, and promote plug and move forward, plug supported flange, venthole is communicated with aqueduct; Now, through high-pressure air pipe to the ventilation of plug air admission hole, can test; After being completed, cylinder resets, and plug leaves flange, is now taken away by flange, namely completes test.Effectively can prevent gas leakage, accurately, work efficiency is high in test.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of pressure testing device of firing chamber aqueduct of gas heater, comprises the venthole 12 that plug 1 high-pressure pipe 2 plug 1 has air admission hole 11 and is connected with air admission hole 11; High-pressure pipe 2 is connected with air admission hole 11 to be connected.
Also comprise a cylinder 3 and pedestal 4,
Described pedestal 4 hollow has upper and lower opening, an end plate of pedestal 4 has passing hole or passing the draw-in groove 42 groove 41, another end plate having upper shed of piston rod,
The cylinder barrel 31 of cylinder 3 is fixedly connected with the end plate of pedestal 4, and piston rod 32 is slidably matched with through hole or through groove 41; Described plug 1 arranges in pedestal 4, and plug 1 is fixedly connected with piston rod 32, and point-blank, venthole 12 is relative with draw-in groove 42 for the axis of venthole 12 and the axis of piston rod 32.Described draw-in groove 42 has upper shed or under shed;
There is toroidal cavity 13 outlet side of described plug 1 around venthole 12.
Described plug 1 there is the axes normal of air admission hole 11 and venthole 12.
Above-described is only preferred embodiments of the present utility model.It should be pointed out that for the person of ordinary skill of the art, when not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
