Abstract
The utility model relates to a hydrant, which is composed of a hydrant body (2), a water pipe connector (1), a discharging pipe (81), a fire-fighting water pipe connector (10), a control section (9), and a discharging valve. The utility model is characterized in that the discharging valve is composed of a spring (3) arranged in a tubular body (21) in the middle part of the hydrant body, a lower support (4), a diaphragm (5), an upper support (6), a guide rod (7), and an upper cover (8) with a sealing ring. The utility model has the advantages of flexible action and reliable work.
Description
The utility model relates to a kind of fire hydrant.
The disclosed fire hydrant of prior art is by the quench key, is contained in the admitting pipe joint below the quench key, is contained in the outlet pipe above the quench key, and the outlet pipe other end connects the fire extinguisher canvas hose joint, and formation is cut down in the control section and the water outlet that are contained in the fire hydrant body side surface.It is spring by being contained in the cylindrical body that its water outlet is cut down, and is that the piston and the loam cake of band sealing ring constitutes on spring.The water outlet of this structure is cut down, moving up and down of its piston is to lean on the action of control section that its top and bottom generation pressure differential is finished, but when the water source that quench is used is unclean, be accompany silt or other impurity in the water, then silt and impurity are easy to enter on the contact-making surface between piston and the cylindrical body, so, moving up and down of piston must increase resistance, makes its motion dumb, can make seizure of piston when serious.With regard to fire-fighting work, it is unallowed above-mentioned accident occurring.
The purpose of this utility model provides a kind of novel fire hydrant, makes its flexible movements, reliable operation.
Solution of the present utility model is: it is by quench key 2, be contained in the admitting pipe joint 1 that has sealing ring below the quench key 2, be contained in the outlet pipe 81 above the quench key 2, be contained in the fire extinguisher canvas hose joint 10 above the outlet pipe 81, formation is cut down in the control section 9 and the water outlet that are contained in quench key 2 sides, its feature is that water outlet cuts down is to be made of following part: the helical spring 3 that is contained in cylindrical body 21 bottoms, lower support 4 is pressed on the helical spring, and its bottom is put into the fairlead of cylindrical body 21 slidably, being bowl-shape rubber diaphragm 5 is placed on the lower support 4 and its outer rim is fixed on the cylindrical body 21, the upper support 6 that is the I shape disk, its underpart is by bolt and diaphragm 5, lower support 4 is fixed together, sealing ring and at least three guide posts 7 are housed on the last transverse plane of upper support 6, the loam cake 8 that has sealing ring is fixed on the quench key by screw, and its upper end is welded together with outlet pipe 81, and phrenic outer rim is tightly pushed down in the lower end in its skirt section that has looping pit.
The advantage of the utility model fire hydrant is: because the diaphragm 5 in the utility model is the convex-concave manner of execution when work, it drives lower support 4 and upper support 6 moves up and down and do not produce friction with any part moves, therefore both made pressure water source contain that silt is more can not to influence its operate as normal yet, it works together very reliable, make by the mixture of the good rubber of elasticity or rubber and fabric owing to diaphragm 5 again, resistance is very little during distortion, and sensitivity is good so the utility model fire hydrant works together.
Description of drawings is as follows:
This accompanying drawing is the structural representation of fire hydrant.
The utility model is described in further detail with regard to accompanying drawing now:
Among the figure 1 is admitting pipe joint, and 2 is the quench key, and 21 for being arranged in the cylindrical body of quench key 2,3 is spring, and 4 is lower support, 5 diaphragms of making for rubber, this diaphragm also can be the mixture of rubber and fabric, and 6 is upper support, and 7 is three guide posts, 8 loam cakes for the band sealing ring, it is fixed on the quench key 2 by screw, on the outer rim that is pressed in diaphragm 5 tightly of the bottom of loam cake 8,81 is outlet pipe, it is welded on the loam cake 8, and 9 is control section, and 10 is the fire extinguisher canvas hose joint, A cuts down mouth for control, B is a control hole, and C is that spilling water cuts down mouth, and D is an osculum, E cuts down mouth for discharging water, F is the dewatering orifice, and G is that mouth is cut down in water outlet, and H is a control lever.M cuts down for control, and N cuts down for discharging water.
The utility model is work like this:
When fire hydrant is not worked, control is cut down M and is in top dead-centre, i.e. control is cut down A and is opened, spilling water cuts down a mouthful C and closes, discharge water and cut down a mouthful E and open, the press water that is come by the water source enters above the diaphragm by admitting pipe joint 1, simultaneously also cut down a mouthful A by control, control hole B enters the lower end of tabula cured 5, at this moment diaphragm 5 raise up under the promotion of spring 3 and drive lower support 4 and upper support 6 moves up, till the upper end of upper support 6 is cut down water outlet a mouthful G by sealing ring and is closed, at this moment the water of outlet pipe 81 the insides discharges water and cuts down a mouthful E by dewatering orifice F, and osculum D enters atmosphere; If make fire hydrant work, then rotation control rod H makes control cut down M and is moved down into bottom dead centre, control this moment is cut down a mouthful A and is closed, spilling water cuts down a mouthful C and opens, discharge water and cut down N and under spring action, close to discharge water and cut down a mouthful E, the water that pressure is arranged below the diaphragm is by control hole B, spilling water cuts down mouthful C and discharge outlet D enters atmosphere, diaphragm 5 in the above press water effect down and the resistance that overcomes spring 3 to recessed and drive upper support 6 and lower support 4 moves down, lower end until lower support 4 contacts with cylindrical body 21, because the moving down of upper support 6 opened water outlet and cut down a mouthful G, then the press water from the water source passes through admitting pipe joint 1, quench key 2 inner chambers, a mouthful G is cut down in water outlet, and outlet pipe 81 is upwards to 10 discharges of fire extinguisher canvas hose joint.
Claims (1)
1. fire hydrant, it is by quench key 2, be contained in the admitting pipe joint that has sealing ring 1 below the quench key 2, be positioned at the outlet pipe 81 above the quench key 2, be contained in the fire extinguisher canvas hose joint 10 above the outlet pipe 81, formation is cut down in the control section 9 and the water outlet that are contained in quench key 2 sides, it is characterized in that it is to be made of following part that water outlet is cut down: the helical spring 3 that is contained in cylindrical body 21 bottoms, lower support 4 is pressed on the helical spring, and its bottom is put into the fairlead of cylindrical body 21 slidably, being bowl-shape rubber diaphragm 5 is placed on the lower support 4 and its outer rim is fixed on the cylindrical body 21, the upper support 6 that is the I shape disk, its underpart is by bolt and diaphragm 5, lower support 4 is fixed together, and sealing ring and at least three guide posts 7 are housed on the last transverse plane of upper support 6, and the loam cake 8 that has sealing ring is fixed on the quench key by screw, its upper end is welded together with outlet pipe 81, and phrenic outer rim is tightly pushed down in the lower end in its skirt section that has looping pit.
