Abstract
The utility model relates to fire extinguishing technology, and discloses a filling valve used for a dry powder extinguisher. The filling valve comprises a valve body, wherein a step-shaped through hole is arranged in the center of the valve body, a valve core is connected on an inlet of the through hole in a threaded mode, and the bottom face of the valve core and an outlet of the through hole are sealed. An air hole is arranged in the middle of the valve core, an inlet of the air hole is arranged in the top portion of the valve core, and an outlet of the air hole is arranged in the side face of the bottom portion of the valve core. The filling valve integrates the functions of powder filling and air inflating, greatly saves production cost, is simple in structure, and saves installation space.
Description
Technical field
The utility model relates to the fire-fighting fire extinguishing technology, particularly a kind of dry powder extinguishing installation filling valve.
Background technique
At present, the application area of powder-type fire extinguisher is increasing.In it was produced, the can of dry powder and the perfusion of pressed gas were the important steps of producing, and need the special device guarantee; But, along with the increase of amount of maintenance, return factory's can dry powder and pressed gas, maintenance cost is large.
Summary of the invention
The purpose of this utility model is to provide a kind of dry powder extinguishing installation filling valve, dry powder and pressed gas can, the dry powder when making things convenient for field maintenance again and pressed gas can in both being convenient to produce.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A kind of dry powder extinguishing installation filling valve is characterized in that, comprises valve body, and the valve body center is provided with stair-stepping through hole, the entrance of the through hole spool that has been threaded, the bottom surface of spool and the exit seal of described through hole; The center of described spool is provided with pore, and the entrance of pore is arranged on the top of spool, and the outlet of pore is arranged on the bottom sides of spool.
Characteristics of the present utility model and further the improvement are:
The entrance of described pore is provided with sealing plug.
The bottom surface of described spool is provided with sealing gasket.
The bottom diameter of described spool is less than the diameter of the counterpart of described valve body.
Described spool circumferentially be provided with seal ring.
Described pore intake section is vertical hole, and exit portion is for being communicated with the transverse holes in vertical hole.
Dry powder extinguishing installation filling valve of the present utility model, the valve body center is provided with stair-stepping through hole, the entrance of the through hole spool that has been threaded, the bottom surface of spool and the exit seal of through hole; The center of described spool is provided with pore, and the entrance of pore is arranged on the top of spool, and the outlet of pore is arranged on the bottom sides of spool.Spin off spool during use, successively can dry powder by the valve body entrance and exit; Spin off sealing plug, screw on spool part screw thread, by the outlet of pore and valve body, can fill pressurized gas, when being filled into specified pressure, screw spool, the outlet of sealed valve body.Like this, aborning or can make things convenient for can dry powder and pressed gas during field maintenance, and filling valve is simple in structure.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation that a kind of dry powder extinguishing installation of the present utility model is used filling valve.
Among the figure: 1, spool; 2, sealing gasket; 3, valve body; 4, sealing plug; 5, seal ring; 6, vertical hole; 7, transverse holes.
Embodiment
With reference to Fig. 1, be a kind of dry powder extinguishing installation filling valve of the present utility model.Wherein, valve body 3 centers are provided with stair-stepping through hole, the entrance of the through hole spool 1 that is threaded, and the bottom surface of spool 1 is bonded with sealing gasket 2, realizes the bottom surface of spool 1 and the exit seal of valve body 3 through holes.The center of spool 1 is provided with pore, and the entrance of pore is arranged on the top of spool 1, and the outlet of pore is arranged on the bottom sides of spool 1; In the present embodiment, the pore intake section is vertical hole 7, and exit portion is for being communicated with the transverse holes 6 in vertical hole 7, and transverse holes 6 is near the bottom of spool 1, and the bottom diameter of spool 1 is less than the diameter of the counterpart of valve body 3, and formation is communicated with the gas channel of valve body 3 outlets.The entrance of pore is provided with sealing plug 4, and the two is for being threaded, and the effect of sealing plug 4 is the obstructions that prevent pore.
During the use of this filling valve, turn round spool 1, then the ultra-fine dry powder of packing into loads onto spool 1, turns round to hemicompact, then fills nitrogen, after having filled, tightens spool 1, and the jam-pack sealing plug 4 again.The present embodiment integrates dress powder aerification function, has greatly saved cost of production, and simple in structure, has saved installing space.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments and applications field, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art in the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification, these all belong to the row of the utility model protection.
