Description

Normally open type multi-bolt-opening indoor fire hydrant

Technical Field

The utility model relates to a fire-fighting equipment field, specificly relate to an indoor fire hydrant of many taps.

Background

The fire hydrant is a fixed fire-fighting equipment, and mainly has the functions of controlling combustible material, isolating combustion-supporting material and eliminating fire source. The indoor fire hydrant is usually arranged in a fire hydrant box body, and because the indoor space is limited, the volume of the traditional multi-hydrant-opening indoor fire hydrant is designed to be smaller, and only one practical hydrant opening is provided. However, since the amount of the combustion-supporting material in the room is large, the spread range in a short time is difficult to control, and many ignition points are generated. Solving the problems of occurrence and spread of fire points in a shorter time becomes the key of indoor fire protection. Usually, the start-up procedure of the indoor fire hydrant should be to open the hydrant gate after connecting the water hose, but such an operation procedure may cause an increase in assembly time due to field factors, resulting in missing the best opportunity to extinguish the fire. Meanwhile, problems such as untight connection between the water belt and the plug port can cause water leakage to cause unstable water pressure, and normal practicability is affected. What is needed is a multiple hydrant port indoor fire hydrant that allows multiple water belts to be linked together while providing practical and effective control of water pressure.

Detailed description of the preferred embodiments

The invention is further described with reference to the following figures and specific examples.

As shown in fig. 1-3, a normally open type indoor fire hydrant with multiple bolt openings comprises a water hose 2 and a hydrant body 1, wherein a rotary switch 11 is arranged at the top of the hydrant body 1, a bolt brake 12 is arranged at the bottom of the hydrant body 1, the rotary switch 11 and the bolt brake 12 are connected through a bolt rod 13, the bolt rod 13 is arranged inside the hydrant body 1, at least 2 bolt openings are arranged on the side wall of the hydrant body 1, a baffle 4 is arranged in the bolt opening 14, a groove 15 is arranged on the inner wall of the bolt opening 14, a spring 3 is arranged in the groove 15, the baffle 4 is connected with the bolt opening 14 through the spring 3, a connecting part 21 is arranged at the tail end of the water hose 2, a fixing flap 211 is arranged at the front end of the connecting part 21, a fixing groove 16 is correspondingly arranged at the outer end of the bolt opening 14 and the fixing flap 211, and a jacking.

By increasing the number of the plug ports 14 to two or more, the practical efficiency and the operational flexibility can be effectively improved. In order to improve the convenience of operation, the utility model relates to a for the open state always, remain the state of opening when state at ordinary times promptly, need keep its holistic closure this moment. The plug opening 14 is closed by the arrangement of the baffle 4 and the spring 3 for pulling the baffle 4 in cooperation with the internal water pressure. In order to ensure the drawing effect, the groove 15 is needed to provide a space for the tension of the spring 3. When the water hose is in operation, the baffle 4 is jacked up by the jacking boss 212 arranged on the connecting part 21 arranged at the tail end of the water hose 2. And finally fixed by screwing the fixing flap 211 provided at the front end of the connection member 21 into the fixing groove 16. The edge of the fixed flap 211 and the inner wall of the fixed slot 16 are provided with magnetic components 6. Since the joint of the water pressure and the tensile force of the spring 3 acts on the connecting part 21, the connecting relation between the connecting part 21 and the bolt opening 14 is strengthened by magnetism by adding the magnetic part 6 in order to ensure the stability of the connecting part and the bolt opening.

As shown in fig. 1, a closed seat 5 for preventing water from overflowing is arranged between the bolt port 14 and the baffle 4, and the closed seat 5 is annular. Because the utility model discloses a constantly keep filling the water state in the normally open design event bolt body 1, bolt mouth 14 and air contact and moist the very likely emergence corrosion condition, and lead to baffle 4 and bolt mouth 14 surface appearance gap to lead to sealed not tight, and water spills over from the gap, causes unnecessary trouble. Through setting up annular seal receptacle 5 cover between tieing mouthful 14 and baffle 4, increase its leakproofness, avoid water direct contact to tie mouthful 14 to lead to tieing mouthful 14 corrosion simultaneously, improve practical life.

As shown in fig. 1 and 5, a water pressure balance pipe 7 is arranged on the side wall of the bottom of the plug body 1, the water pressure balance pipe 7 comprises a pressure detection device 71 and an electric valve 72, the pressure detection device 71 is arranged on the inner wall of the water pressure balance pipe 7, the electric valve 72 is arranged at the free end port of the water pressure balance pipe 7, and the pressure detection device 41 is electrically connected with the electric valve 72. Because of the limited range of indoor fire protection operations, there is no need for significant water pressure to spray as is required for outdoor fire protection. Meanwhile, excessive water pressure can cause secondary damage to the indoor environment, so that by arranging the water pressure balance pipe 7 and adjusting the pressure monitoring device 71, when the water pressure is detected to reach a preset threshold value for the water pressure balance pipe 7, the electric valve 72 is started, and a small amount of water is discharged from the water pressure balance pipe 7 so as to balance the water pressure of the bolt body 1.

As shown in fig. 1, the number of the openings 14 is 3, and the first opening 141, the second opening 142 and the third opening 143 are arranged from top to bottom. The first plug port 141 is larger in diameter than the second plug port 142 and the third plug port 143, and the second plug port 142 is larger in diameter than the third plug port 143. Due to space constraints, too many sockets cannot be provided, but three sockets 14 with different diameters are chosen to meet the practical requirements of different pressures and different fluxes. Since the water pressure in the plug body 1 increases from top to bottom, the maximum flux but the minimum water pressure can be ensured by setting the first plug port 141 as the maximum plug port, and the water can be influenced by the water outlet of the second plug port 142 and the third plug port 143. Similarly, the third plug port 143 is set to a minimum, which ensures maximum water pressure and minimum flux without affecting the normal operation of the other plug ports 14.

As shown in figure 1, the inner wall of the bolt body 1 is provided with a rust-proof layer 8. Because the bolt body 1 is kept in a damp water-filled state in the normally open design, the bolt body 1 is easily corroded by various ions in water, the safety of the bolt body 1 can be reduced along with the time and the water pressure, and the antirust layer 8 is arranged to provide antirust protection for the bolt body 1 and various metal parts and prevent the water pressure from directly acting on the inner wall of the bolt body 1. The antirust layer 8 is made of rubber, silica gel and plastic. Rubber, silica gel and plastic have certain elasticity, have certain buffer action on water pressure, and the material is inert, and hardly generates corrosion damage due to water.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
