Abstract
The utility model provides a fire control reducing crossover sub, includes that the cylindric connects the body, the cylindric connects the body and includes drum section, round platform section of thick bamboo section, drum section down, the cylindric connect the body last port, down port department be provided with interface agent, connect the body both ends and be equipped with the annular groove, seal ring adorns in annular groove department, the interface agent outer wall be equipped with more than one be used for with the spanner screens of spanner cooperation work, the interface agent tip division has two above jack catch grooves, the jack catch sets up in jack catch groove department. The utility model provides a fire -fighting water pipe dimension variation in size in supplying water in the scene of fire, problem that the bayonet socket form is different, have the fire control of being convenient for soldier when putting out a fire fire hose do not knot the material resources of using manpower sparingly again, water supply time, and process simple advantage.
Description
Technical field
The utility model relates to fire-fighting equipment field, is specifically related to the reducing crossover sub connecting fire-prevention pipe in a kind of water system.
Background technique
Fire-fighting truck scene of fire utilizes suction sleeve absorb water or utilize in nurse tanker water supply process, because each fire-fighting party on duty fire-prevention pipe interface size is different, bayonet socket form is different, the problem that cannot connect easily is there is in connection procedure, easily cause the delay on fire-fighting fire extinguishing setup time, cause irremediable loss.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of and solves fire-prevention pipe interface size difference in the water supply of scene of fire, the problem that bayonet socket form is different, be convenient to fire-extinguisher water hose when fire fighters is put out a fire do not tie a knot simultaneously, can use manpower and material resources sparingly again, water supply time, and process simple fire-fighting reducing crossover sub.
The technical solution of the utility model is: comprise cartridge fittings body, cartridge fittings body comprises cylindrical section, frustum cone cylinder section, lower cylindrical section, upper end-hole, the lower end mouth place of cartridge fittings body are provided with interface agent, joint body two end part are provided with annular groove, seal washer is loaded on annular groove place, interface agent outer wall is provided with multiple for the spanner screens with spanner cooperating, and interface agent end has two or more claw groove, and claw is arranged at claw groove place.
Described interface agent is individually fixed in the upper end-hole place of cylindrical section, the lower end mouth place of lower cylindrical section.
Described claw is welded in claw groove place.
Described annular groove is stepped shape groove, and the inner ring of seal washer is provided with the boss that a circle and stepped shape groove fit are assembled.
The utility model adopts two interface agent and two seal washers being with multi-form claw, thus better protects the safety of joint, reduces potential safety hazard; Play robust sealed by spanner screens, good seal performance, liquid is little by resistance; The bore at joint body two ends is all not identical with form, meets the demand of different exterior line interface to greatest extent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is locking mechanism schematic diagram of the present utility model.
Embodiment
The embodiment provided below in conjunction with accompanying drawing is further described the utility model.
In Fig. 1,2, the utility model comprises the joint body 1 of hollow shape, the interface agent 1 of band claw 3, the interface agent 25 of band claw 7, seal washer 1, seal washer 28, the spanner screens 6 be arranged on interface agent.The joint body of a hollow shape comprises two axial openings, and the internal diameter at one of them axially open place reduces gradually, makes two axial opening inside diameter differences.The both ends open of joint body 1 arranges the claw interface of different size, axial two interface agents are provided with spanner screens, screw extruding by spanner screens and play lock sealing effect, inclination angle is provided with between claw and joint body, inclination angle is 3 ° ~ 8 °, and inclination angle is claw and the direct angle of joint body, when in an assembling process by spanner external force, crossover sub place is engaged, thus reaches safe locking.Claw is distributed in circumferentially same.Reducing crossover sub jointing arranges rubber gasket, and seal washer inner peripheral surface is provided with the boss of a ring shape, is combined completely by annular boss with interface groove, thus seal washer and joint body are tightly connected, difficult drop-off.
During use, first the band interface agent 1 of claw 3 is docked with the wide internal chute 11 of tube tooth interface 9, seal washer 1 docks with the seal washer 10 of tube tooth interface, by spanner screens 6, by the locking direction symbol of joint, the interface agent 1 of the band claw 3 of docking and tube tooth interface 9 are screwed extruding, sealing is close to; With spanner, the interface agent 25 of the band claw 7 of docking and another tube tooth interface are screwed extruding successively, sealing is close to, thus reaches safe locking; When reducing crossover sub being separated with tube tooth interface, by the detaching direction rotation of joint and separable.
