Abstract
The utility model discloses a fast opening device for a hydrant, which comprises a body arranged at the upper end of the hydrant; a pressure rod is also arranged on the body; a valve rod of the hydrant penetrates through the body to be matched with the pressure rod. The fast opening device for the hydrant is simple in structure and low in cost and solves the defect that the hydrant cannot be opened due to overlarge water pressure caused by the rusting of a spiral opening device in a way that the valve rod is directly driven by the pressure rod to downwards move.
Description
Technical field
The utility model relates to fire gear, is specifically related to a kind of fire hydrant quick opening.
Background technique
Existing fire hydrant mostly is spiral opening device, thereby the valve rod that rotarily drives by screw rod moves down Open valve, in this, opening device exists the opening time long, does not use screw thread to get rusty for a long time stuck, and situation about can not open in the situation that hydraulic pressure is excessive.Brought serious potential safety hazard.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of fire hydrant quick opening.
The technical solution of the utility model is: a kind of fire hydrant quick opening, comprise the body that is arranged on fire hydrant upper end, and on described body, be also provided with depression bar, the valve rod of described fire hydrant mates with described depression bar through described body.
Further improvement of the utility model comprises:
On described body, be also provided with for limiting the limited part of depression bar stroke.
Described depression bar stroke both sides are provided with dividing plate, and described dividing plate is fixed on described body, also offer lockhole on described dividing plate, and the bolt mating with described lockhole, and one section of bolt is provided with through hole.
The utility model is simple in structure, and cost is low, by depression bar, is directly with ovable valve stem to move downward, and getting rusty of having solved that spiral opening device exists is stuck, the excessive drawback that can not open of hydraulic pressure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, body, 2, depression bar, 3, valve rod, 4, limited part.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of fire hydrant quick opening of the utility model, comprises the body 1 that is arranged on fire hydrant upper end, on described body 1, is also provided with depression bar 2, and the valve rod 3 of described fire hydrant mates with described depression bar 2 through described body 1.On described body 1, be also provided with for limiting the limited part 4 of depression bar 2 strokes.
Described depression bar 2 stroke both sides are provided with dividing plate, and described dividing plate is fixed on described body 1, also offers lockhole on described dividing plate, and the bolt mating with described lockhole, and one section of bolt is provided with through hole.Effectively prevented that fire hydrant from being occurred by the behavior of maliciously opening or stealing.
The utility model in use, only need to be extracted the bolt for locking out, presses depression bar 2 and moves downward and can open valve, meanwhile, screw rod is inserted to lockhole and can make fire hydrant always in open mode.After use finishes, extract screw rod out, be reset to limited part 4 positions under the effect of valve rod 3 Returnning springs, fire hydrant is closed.
The utility model is simple in structure, and cost is low, by depression bar 2 directly band ovable valve stem 3 move downward, getting rusty of having solved that spiral opening device exists is stuck, the excessive drawback that can not open of hydraulic pressure.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
