Description

Technical Field

[0001] This utility model relates to the field of manual / automatic fire valve technology, and in particular to a valve. Background Technology

[0002] Fire valves are an important accessory for controlling pipelines in industrial and building systems. They are used to control water flow, pressure, and direction in fire protection systems to ensure the normal operation of the fire protection system and the effectiveness of fire extinguishing.

[0003] Staff often find that in the process of using the current manual-automatic fire valves, in order to carry out firefighting efficiently, the current fire valves are usually equipped with automatic control systems. However, the control equipment for automatic control is mostly electrical equipment. When the power system is damaged by fire, the valves will not work properly, thus hindering the rescue operation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a manual / automatic integrated fire valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a manual / automatic fire valve, comprising a valve body, a connecting seat fixedly connected to the valve body, a valve stem disposed on the connecting seat, a rotating shaft rotatably connected to the valve body, a gate body disposed on the rotating shaft, a gear fixedly connected to the valve stem, a rack meshing with the gear, a sliding connection between the connecting seat and the rack, a motor fixedly connected to the connecting seat, a screw fixedly connected to the output shaft of the motor, the screw threadedly connected to the rack, a conversion structure disposed on the connecting seat, the conversion structure mainly consisting of a rotating disk rotatably connected to the connecting seat, a rotating rod rotatably inserted into the valve body, a sliding connection between the rotating disk and the valve stem, a rectangular rod fixedly connected to the valve stem, a sliding connection between the rectangular rod and the rotating rod, and a handwheel fixedly connected to the valve stem.

[0006] The aforementioned components achieve the following effect: a sensor installed on the valve body detects a fire. When a fire is detected, the controller starts the motor, which in turn drives the screw to rotate, causing the rack to slide and the gear to rotate. This causes the valve stem to rotate and open or close the door. When the electrical system is damaged, the operator can press down the handwheel to insert the rectangular rod into the rotating rod. At this time, the gear moves away from the rack, disengaging from it. The valve stem can then be rotated by the handwheel, causing the rotating rod to rotate and open the door. This avoids the problem that current fire valves are usually equipped with automatic control systems for efficient firefighting. However, most of the control equipment for these automatic control systems is electrical. When the electrical system is damaged by a fire, the valve will not function properly, thus hindering rescue operations.

[0007] Preferably, two fixing blocks are fixedly connected to the valve stem, two sliding rods are provided on the rotating disk, a limit rod is fixedly connected to the sliding rod, and a limit groove is formed on the fixing block.

[0008] The effect achieved by the above components is that, under normal conditions, inserting the limit rod into the limit groove can limit the fixed block and prevent the gear from falling when the power system is normal.

[0009] Preferably, the rotating disk has a sliding groove, and the sliding groove is slidably connected to the sliding rod.

[0010] The effect achieved by the above components is that the sliding rod slides within the sliding groove, making the position of the sliding rod more stable.

[0011] Preferably, a first spring is fixedly connected to the fixing block, and one end of the first spring is fixedly connected to the rotating disk.

[0012] The effect achieved by the above components is as follows: when the limiting rod is inserted into the limiting groove, the first spring is in a stretched state. Therefore, when the sliding rod is slid outward to make the limiting rod move away from the limiting groove, the fixing block will descend under the action of the rebound force of the two first springs, making the operation more convenient and improving the fire fighting efficiency.

[0013] Preferably, the door body is provided with an installation structure, which mainly consists of two sliding grooves. Both sliding grooves are opened on the door body, and an installation block is slidably inserted in the sliding groove. The rotating rod and the rotating shaft are both provided with installation grooves, and two sealing strips are fixedly connected to the door body.

[0014] The above components achieve the following effects: the sliding mounting block can be inserted into the corresponding mounting groove to quickly install the door body into the valve body; conversely, the door body can be removed and replaced. The sealing strip is made of rubber, which can improve the sealing effect.

[0015] Preferably, a slide rod is slidably connected in the slide groove, and the slide rod is fixedly connected to the mounting block.

[0016] The effect achieved by the above components is that the operator can slide the mounting block by sliding the sliding rod.

[0017] Preferably, a second spring is fixedly connected to the slide rod, and one end of the second spring is fixedly connected to the inner wall of the slide groove.

[0018] The effect achieved by the above components is that when the mounting block is inserted into the mounting slot, the second spring is in a contracted state, so the rebound force of the second spring acts on the slide rod, making the installation more stable.

[0019] Preferably, a knob is rotatably connected to the door body, and two pull ropes are fixedly connected to the knob, with the pull ropes being fixedly connected to the slide rod.

[0020] The effect achieved by the above components is that when the knob is turned, the two pull ropes will be wound up, which in turn will cause the two slide rods to slide closer together in sync, making the installation operation more convenient.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a conversion structure, a sensor is set on the valve body to detect fire. When a fire is detected, the controller controls the motor to start, which in turn drives the screw to rotate, causing the rack to slide, which in turn drives the gear to rotate, causing the valve stem to drive the door to rotate to open or close. When the circuit system is damaged, the operator can press down the handwheel to insert the rectangular rod into the rotating rod. At this time, the gear moves away from the rack and disengages from it. Then, the valve stem can be rotated by the handwheel, causing the rotating rod to drive the door to rotate. This avoids the problem that current fire valves are usually equipped with automatic control systems for efficient fire fighting. However, the control equipment for automatic control is mostly electrical equipment. When the power system is damaged by fire, the valve will not work properly, thus hindering the rescue operation.

[0027] Example 1, such as Figures 1 to 3 As shown, a manual / automatic fire valve includes a valve body 1, a connecting seat 2 fixedly connected to the valve body 1, a valve stem 3 provided on the connecting seat 2, a rotating shaft 5 rotatably connected to the valve body 1, a gate body 4 provided on the rotating shaft 5, a gear 6 fixedly connected to the valve stem 3, a rack 9 meshing with the gear 6, the connecting seat 2 and the rack 9 slidably connected, a motor 11 fixedly connected to the connecting seat 2, a screw 10 fixedly connected to the output shaft of the motor 11, and the screw 10 threadedly connected to the rack 9.

[0028] Reference Figure 2 and Figure 4 The connecting seat 2 is equipped with a conversion structure 7, which mainly consists of a rotating disk 71. The rotating disk 71 is rotatably connected to the connecting seat 2. A rotating rod 72 is rotatably inserted into the valve body 1. The rotating disk 71 is slidably connected to the valve stem 3. A rectangular rod 74 is fixedly connected to the valve stem 3 and is slidably connected to the rotating rod 72. A handwheel 73 is fixedly connected to the valve stem 3. A sensor is installed on the valve body 1 to detect fire. When a fire is detected, the controller starts the motor 11, which in turn drives the screw 10 to rotate, causing the rack 9 to slide. This, in turn, drives gear 6 to rotate, causing valve stem 3 to rotate and open or close door 4. When the electrical system is damaged, the operator can press down handwheel 73, causing rectangular rod 74 to insert into rotating rod 72. At this time, gear 6 moves away from rack 9, disengaging from it. Then, valve stem 3 can be rotated via handwheel 73, causing rotating rod 72 to rotate door 4. This avoids the current fire valves being equipped with automatic control systems for efficient firefighting. Most of the control equipment for automatic control is electrical equipment. When the power system is damaged by fire, the valves may malfunction, hindering rescue operations. Two fixed blocks 75 are fixedly connected to the valve stem 3, and two sliding rods 77 are provided on the rotating disk 71. Limit rods 78 are fixedly connected to the sliding rods 77, and limit grooves 79 are provided on the fixed blocks 75. Under normal conditions, the limit rods 78 are inserted into the limit grooves 79 to limit the fixed blocks 75, preventing the gear 6 from falling when the power system is normal. A sliding groove 76 is provided on the rotating disk 71, and the sliding groove 76 connects to the sliding rods... The sliding connection 77 allows the sliding rod 77 to slide within the sliding groove 76, making its position more stable. A first spring 710 is fixedly connected to the fixed block 75, with one end of the first spring 710 fixedly connected to the rotating disk 71. When the limiting rod 78 is engaged in the limiting groove 79, the first spring 710 is in a stretched state. Therefore, when the sliding rod 77 is slid outward, causing the limiting rod 78 to move away from the limiting groove 79, the fixed block 75 descends under the rebound force of the two first springs 710, making operation more convenient and improving firefighting efficiency.

[0029] Reference Figure 3The door body 4 is equipped with an installation structure 8, which mainly consists of two sliding grooves 81. Both grooves 81 are located on the door body 4, and installation blocks 83 are slidably inserted into them. Installation slots 84 are provided on both the rotating rod 72 and the rotating shaft 5. Two sealing strips 88 are fixedly connected to the door body 4. By sliding the installation blocks 83 and engaging them into the corresponding installation slots 84, the door body 4 can be quickly installed in the valve body 1. Conversely, the door body 4 can be removed and replaced. The sealing strips 88 are made of rubber, which improves the sealing effect. A sliding rod 82 is slidably connected to the sliding groove 81, and the sliding rod 82 is fixedly connected to the installation block 83. Operators can slide the rod through the groove. The sliding rod 82 drives the mounting block 83 to slide. A second spring 85 is fixedly connected to the sliding rod 82. One end of the second spring 85 is fixedly connected to the inner wall of the sliding groove 81. When the mounting block 83 is inserted into the mounting groove 84, the second spring 85 is in a contracted state. Therefore, the rebound force of the second spring 85 acts on the sliding rod 82, making the installation more stable. A knob 87 is rotatably connected to the door body 4. Two pull ropes 86 are fixedly connected to the knob 87. The pull ropes 86 are fixedly connected to the sliding rod 82. When the knob 87 is rotated, the knob 87 will drive the two pull ropes 86 to wind up, thereby driving the two sliding rods 82 to slide closer together synchronously, making the installation operation more convenient.

[0030] Working principle: A sensor on valve body 1 detects a fire. When a fire is detected, the controller starts motor 11, which drives screw 10 to rotate, causing rack 9 to slide, which in turn drives gear 6 to rotate, causing valve stem 3 to rotate and door body 4 to rotate to open or close. When the circuit system is damaged, the operator can press down handwheel 73, causing rectangular rod 74 to insert into rotating rod 72. At this time, gear 6 moves away from rack 9, disengaging from it. Then, handwheel 73 can be used to rotate valve stem 3, causing rotating rod 72 to rotate door body 4. This avoids the situation where current fire valves are usually equipped with automatic control systems for efficient firefighting. However, the control equipment for automatic control is mostly electrical equipment. When the power system is damaged by fire, the valve will not work properly, hindering the rescue operation. Under normal conditions, limit rod 78 is inserted into limit groove 79 to limit fixed block 75, preventing gear 6 from falling and sliding rod from sliding when the power system is normal. The sliding rod 77 slides within the sliding groove 76, making its position more stable. When the limiting rod 78 is engaged in the limiting groove 79, the first spring 710 is under tension. Therefore, when the sliding rod 77 is slid outward, causing the limiting rod 78 to move away from the limiting groove 79, the fixing block 75 descends under the rebound force of the two first springs 710, making operation more convenient and improving firefighting efficiency. The sliding mounting block 83 is then engaged in the corresponding mounting groove 84, allowing the door body 4 to be quickly installed in the valve body 1. The door body 4 can be removed for replacement. The sealing strip 88 is made of rubber, which can improve the sealing effect. The operator can slide the mounting block 83 by sliding the sliding rod 82. When the mounting block 83 is inserted into the mounting groove 84, the second spring 85 is in a contracted state. Therefore, the rebound force of the second spring 85 acts on the sliding rod 82, making the installation more stable. Turning the knob 87 will drive the two pull ropes 86 to wind up, thereby driving the two sliding rods 82 to slide closer together synchronously, making the installation operation more convenient.
