Abstract
The utility model relates to a pagoda-type fire hose inlet connector with a pressure relief orifice plate, which comprises an outer pipe joint, an inner pipe axis, and a pressure relief orifice plate which is arranged on the top of the inner pipe axis and integrated with the inner pipe axis. The aperture of the pressure relief orifice plate is smaller than the aperture of the inner pipe axis. The pressure relief orifice plate can be flexibly connected with the inside of the inner pipe axis. A spring is arranged between the pressure relief orifice plate and the top of the inner pipe axis. As the aperture of the pressure relief orifice plate is smaller than the aperture of the inner pipe axis, the pagoda-type fire hose inlet connector has the function of decompression and pressure stabilization, and effectively protects hoses from being broken. In addition, the flow rate of the effluent water is small and water is saved.
Description
Technical field
The utility model relates to a kind of fire hose water supply connector, relates in particular to the water supply connector of a kind of pagoda-shaped band pressure reducing orifice fire hose.
Background technique
The same size with the aperture of interior tubular axis of the outer tube joint of existing fire hose water supply connector when hydraulic pressure is excessive, is easy to cause the flexible pipe explosion, brings the waste of water resources thus.
Summary of the invention
The utility model to provide a kind of and can play decompression, pressure stabilization function in order to solve the problems of the technologies described above, and avoids the excessive pagoda-shaped band pressure reducing orifice fire hose water supply connector that causes the phenomenon generation of flexible pipe explosion of hydraulic pressure.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises outer tube joint, interior tubular axis, and described interior tubular axis is provided with a pressure reducing orifice, and the aperture of pressure reducing orifice is less than the aperture of interior tubular axis.
As preferably, the aperture of described pressure reducing orifice be described in tubular axis the aperture 1/2nd.
As preferably, described pressure reducing orifice is positioned at the top of described tubular axis, and pressure reducing orifice and interior tubular axis are one.
As preferably, described pressure reducing orifice be movably connected in described in the tubular axis, be provided with spring between the top of pressure reducing orifice and interior tubular axis.
The beneficial effects of the utility model are: because the orifice plate diameter is littler than interior tubular axis, play decompression, pressure stabilization function, protected flexible pipe effectively.Water outlet simultaneously is little, has also saved water resources.
Description of drawings
Fig. 1 is a kind of axial sectional structure schematic representation of the present utility model.
Fig. 2 is another axial sectional structure schematic representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: the pagoda-shaped band pressure reducing orifice fire hose water supply connector of present embodiment, as shown in Figure 1, comprise outer tube joint 1, interior tubular axis 4, one and interior tubular axis all-in-one-piece pressure reducing orifice 2 are arranged on the top of interior tubular axis, the aperture of pressure reducing orifice be interior tubular axis the aperture 1/2nd, play decompression.
Embodiment 2: the pagoda-shaped band pressure reducing orifice fire hose water supply connector of present embodiment, as shown in Figure 2, in interior tubular axis 4, be connected with a pressure reducing orifice 2, and between the top of pressure reducing orifice 2 and interior tubular axis 4 spring 3 is installed, remaining is with embodiment 1.Under the pressure of water, pressure reducing orifice and spring are regulated automatically.
