Description
Technical Field
The utility model belongs to the technical field of the fire control, concretely relates to forest fire hose connects crossover sub. The adapter joint is mainly applied to the high-pressure-resistant, wear-resistant and high-tightness connection between special-shaped interfaces of fire hoses for fire fighting water supply and fire extinguishment.
Background
At present, the hose joints for fire fighting are more in types, and besides the commonly used quick joints and clamping joints, american threaded joints, clamping joints special for forest fire fighting hoses and the like exist, and the fire fighting hose joints designed and used in different structures or different fields have certain differences. Under some conditions, joints of different water hoses need relay water supply, but the water hoses cannot be directly connected with each other due to different joints, and in order to ensure that fire extinguishers smoothly and mutually and alternately connect the 40-type American internal thread connector and the 40-type forest fire fighting card connector in the water hose connection process, a conversion joint meeting the use requirement needs to be developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a crossover sub is connected to forest fire hose, it can be with the American female connector of 40 types and 40 types forest fire control card formula interface interconversion connection.
The technical scheme of the utility model as follows: the connection adapter for the forest fire hose comprises a forest hose interface, a sealing washer and an external thread interface, wherein the sealing washer is arranged on the upper end face of the forest hose interface, and the external thread interface is arranged on the lower portion of the forest hose interface.
And the outer side of the sealing washer is provided with a ring groove.
And a flange is arranged at the contact part of the forest water belt interface and the sealing washer.
The flange is clamped in the ring groove of the sealing washer,
the port of the external thread interface is flat.
The sealing washer is arranged at the connecting part of the forest water belt buckle and the buckle.
The beneficial effects of the utility model reside in that: 1) The 40-type American internal thread interface and the 40-type forest fire fighting card type interface are mutually converted and connected; 2) The connection between the water hoses with different types of interfaces is convenient and quick; 3) The conversion interface has excellent material quality and is firm and durable; 4) The conversion interface is sealed well when in use.
