Abstract
The utility model discloses a shower nozzle for dashing dirt pipeline, including the tubular column, the one end of tubular column is provided with the toper export that the cross -section diminishes gradually along water flow direction, the other end of tubular column is provided with the quick -operation joint with water feeding line's model looks adaptation. The utility model discloses a sprinkler structure is simple, low cost, and through the spired export of the one end with tubular column design, when the fluid export through the toper, owing to circulate the cross -section and diminish gradually, velocity of flow grow relatively to concentrated, the distance water column far away of can spouting.
Description
Technical field
The utility model relates to dust control technology field, particularly relates to a kind of shower nozzle for rushing dirt pipeline.
Background technology
Coal dust that coal mine produces in process of production, dust, can serious harm underground operators healthy, coal dust can produce to burn and explosion hazard simultaneously, so dust-proof working must conscientiously be carried out. Tunnel, down-hole measurements for reduction along the line mainly contains tunneling boring spraying and rushes dirt watering.
At present, tunnel, down-hole is rushed dirt watering and is normally drawn from main water line by current by high-pressure rubber pipe, and owing to flow velocity is lower, the water sprayed out from sebific duct port compares dispersion, and the distance of ejection is also relatively near, and this brings inconvenience to depositing dust work.
Summary of the invention
For the problems referred to above, a kind of shower nozzle of proposition of the present utility model, it is possible to spray more concentrated and apart from farther water column when pressure of supply water is constant.
The technical solution of the utility model is achieved in that
For rushing a shower nozzle for dirt pipeline, comprising tubing string, one end of described tubing string is provided with the conical outlet that cross section diminishes gradually along current direction, and the other end of described tubing string is provided with the rapid-acting coupling suitable with the model of water supply line.
Further, described tubing string is formed from steel.
Further, described rapid-acting coupling adopts welding process to be connected with described tubing string.
Nozzle structure of the present utility model is simple, with low cost, and by one end of tubing string is arranged to conical outlet, when fluid is by conical outlet, owing to flow area diminishes gradually, flow velocity becomes big relatively such that it is able to that ejection is concentrated, apart from farther water column.
Accompanying drawing explanation
Fig. 1 is the structural representation of the shower nozzle for rushing dirt pipeline of the utility model embodiment.
In figure:
1, tubing string; 2, conical outlet; 3, rapid-acting coupling.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, according to a kind of shower nozzle for rushing dirt pipeline of the present utility model, comprise tubing string 1, one end of tubing string 1 is provided with the conical outlet 2 that cross section diminishes gradually along current direction, by conical outlet 2 is arranged in one end of tubing string 1, when fluid is by conical outlet 2, the principle of continuity according to flow of fluid, unit time is all equal by the fluid mass in each cross section of conical outlet 2, along with the flow area of conical outlet 2 is more and more less, the flow velocity of conical outlet 2 is increasing, thus finally sprays that concentrate, distant water column. Confirm to adopt the shower nozzle of the present embodiment water column jet length can be brought up to 7-8 doubly.
It should be noted that " the current direction " that use in literary composition refers to that water flows to the direction of the conical outlet 2 of shower nozzle along shower nozzle from water supply line.
In order to realize being connected with the quick of water supply line, the other end of tubing string 1 is provided with the rapid-acting coupling 3 suitable with the model of water supply line, and such as, if the model of water supply line is KJ16, then selection model is the rapid-acting coupling of KJ16.
Tubing string 1 is formed from steel, it may be preferred that tubing string 1 and rapid-acting coupling 3, by being welded together, adopt welding process not only to connect reliably, and good seal performance.
The manufacture of this device is simple, low production cost, is improved by simple structure and just can spray concentrated distant water column.
The foregoing is only better embodiment of the present utility model, not in order to limit the utility model, all within purport of the present utility model, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
