Description

Technical Field

[0001] The utility model relates to the technical field of vertical fire pumps, in particular to a vertical fire pump with adjustable water pressure at a water outlet. Background Art

[0002] A vertical fire pump refers to a fire pump that adopts a special hydraulic design and structural design, so that it has a flow-pressure gradation that is more suitable for building fire water supply systems than ordinary centrifugal clean water pumps, and the flow-pressure characteristic curve is flat and has no hump.

[0003] The special hydraulic design and structural design make it more suitable for building fire water supply system with flow and pressure grading than ordinary centrifugal clean water pumps, and the flow-pressure characteristic curve is flat without hump. All parts of the friction parts due to rotation are made of wear-resistant, corrosion-resistant and anti-meshing materials, which have high reliability. The multi-stage pump can be equipped with double water outlets, and the pump body has high bearing capacity, strong anti-overload ability and sensitive start-up.

[0004] In the water supply system, water pressure regulation plays a key role in ensuring the stability and normal operation of water supply. Reasonable water pressure regulation can ensure that the water flow rate in the water supply network is moderate and avoid problems such as pipe blockage or leakage. At the same time, water pressure regulation can also improve the efficiency of the water supply system and reduce energy consumption.

[0005] Vertical fire pumps need to be drained and the water pressure needs to be adjusted. When using a vertical fire pump, the water pressure in the vertical fire pump needs to be adjusted. Otherwise, it will be difficult to connect the vertical fire pump, making it difficult to connect the vertical fire pump and the water pressure at the outlet difficult to adjust. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a vertical fire pump with adjustable water pressure at the water outlet.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A vertical fire pump with adjustable water pressure at a water outlet comprises a vertical fire pump, a motor is fixedly mounted on the top of the vertical fire pump, and a water inlet is fixedly mounted on one side of the vertical fire pump;

[0009] A water outlet is arranged on the other side of the vertical fire pump, one end of the water outlet is connected with a connecting water pipe, a fire sprinkler is arranged at the end of the connecting water pipe, and a pressing assembly is arranged at the rear side of the fire sprinkler.

[0010] In addition, a preferred structure is that the pressing assembly includes a pressing piece, the pressing piece is arranged on the outside of the pressing assembly, and a return spring is arranged at the bottom of the pressing assembly, and an extrusion plate is arranged at the bottom of the return spring.

[0011] In addition, a preferred structure is that the end of the extrusion plate is in extrusion contact with the connecting water pipe.

[0012] In addition, a preferred structure is that a fixed base is provided at the bottom of the vertical fire pump, and the fixed base is "L"-shaped for better fixation.

[0013] In addition, a preferred structure is that when the pressing member is pressed to overlap with the pressing assembly, the contact between the extrusion plate and the connecting water pipe is the deepest.

[0014] In addition, a preferred structure is that when the return spring is in a fully squeezed state, the squeezing plate is in the deepest state and the water pressure is maximum at this time.

[0015] The beneficial effects of the utility model are as follows: the vertical fire pump can be connected to the outside through the fixed installation, and when it is necessary to connect to the outside, the pressure of the water outlet needs to be adjusted, and the pressure is adjusted by rotating, which makes the adjustment simpler and more convenient for people to use.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A vertical fire pump with adjustable water pressure at a water outlet comprises a vertical fire pump 2, a motor 1 is fixedly mounted on the top of the vertical fire pump 2, and a water inlet 3 is fixedly mounted on one side of the vertical fire pump 2;

[0023] A water outlet 5 is provided on the other side of the vertical fire pump 2 , one end of the water outlet 5 is connected to a connecting water pipe 6 , a fire sprinkler 8 is provided at the end of the connecting water pipe 6 , and a pressing assembly 7 is provided at the rear side of the fire sprinkler 8 .

[0024] Among them, the pressing component 7 includes a pressing piece 71, which is arranged on the outside of the pressing component 7, and a return spring 72 is arranged at the bottom of the pressing component 7, and an extrusion plate 73 is arranged at the bottom of the return spring 72. The return spring 72 can effectively reset the pressing piece 71.

[0025] At the same time, the end of the pressing plate 73 is pressed and contacted with the connecting water pipe 6. When the end of the pressing plate 73 is pressed and contacted with the connecting water pipe 6, the water pressure in the connecting water pipe 6 can be adjusted.

[0026] In addition, a fixed base 4 is provided at the bottom of the vertical fire pump 2, and the fixed base 4 is "L"-shaped, so that it is better fixed.

[0027] Moreover, when the pressing member 71 is pressed to overlap with the pressing assembly 7, the contact between the extrusion plate 73 and the connecting water pipe 6 is the deepest. When the return spring 72 is in a completely squeezed state, the extrusion plate 73 is in the deepest state, and the water pressure is the highest at this time.

[0028] In this embodiment, the vertical fire pump 2 is first fixedly installed on the ground through the fixed base 4, and the water inlet 3 is connected to the groundwater, and then the groundwater enters the vertical fire pump 2.

[0029] Then the motor 1 is fixedly installed on the vertical fire pump 2, and the water outlet 5 at the other end of the vertical fire pump 2 is connected to the connecting water pipe 6, and then the water pressure is adjusted by the pressing component 7 at one end of the fire sprinkler 8. When no pressing is performed, it is normal, and the water flow will pass through the connecting water pipe 6 and then be sprayed out through the fire sprinkler 8.

[0030] When the water pressure is low, you only need to press the pressing piece 71. The pressing piece 71 will drive the return spring 72 at the bottom to make the extrusion plate 73 squeeze the connecting water pipe 6. At this time, the connecting water pipe 6 will be squeezed, so that the water pressure inside the connecting water pipe 6 will increase, causing the outgoing water flow to become larger and larger.

[0031] When encountering a high water pressure, just loosen the pressing piece 71. The pressing piece 71 drives the reset spring 72 at the bottom to make the extrusion plate 73 relax the connecting water pipe 6. The reset spring 72 drives the pressing piece 71 to reset. At this time, the connecting water pipe 6 will be relaxed, so that the water pressure inside the connecting water pipe 6 will be reduced, causing the outgoing water flow to become smaller and smaller.

[0032] In the utility model, the vertical fire pump 2 can be connected to the outside by fixed installation, and when it is necessary to connect to the outside, the pressure of the water outlet needs to be adjusted, and the pressure is adjusted by pressing, which makes the adjustment simpler and more convenient for people to use.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
