Water flow indicator is an important accessory used to visually observe and manage the flow of media. It can observe the flow of gas and steam at any time. In many production, it is an indispensable accessory. At present, its types mainly include thread type, welding type, flange type and saddle type. The water flow indicator can be applied to the automatic sprinkler system. It can timely send the flow direction of water quality to the electric control box in the form of electrical signals. The following is a brief introduction to the main technical requirements of the water flow indicator.
1. Basic work requirements
Under normal conditions, the working pressure of this water flow indicator is required to be about 1.2 MPa. At the same time, its delay performance is required to be adjustable. Generally, it needs to be tested to determine its delay time according to the actual situation. In this case, its adjustable range is required to be a state between two seconds and 90 seconds.
2. Material requirements
There is a reason why the material requirements are included in the technical requirements. After all, the working range of the water flow indicator is very special. It is impossible to ensure the sensitivity of materials without certain corrosion resistance. Therefore, it needs to be determined that this material has strong corrosion resistance, and non-metallic materials are generally used as one of the main materials.
3. Impact resistance
Under normal circumstances, it is required to ensure that its impact resistance reaches the impact of 6.8j, which can ensure that the parts will not become loose. Therefore, under the impact of high-intensity water flow, the type of fracture should not be considered.
4. Sensitivity
The sensitivity requirement is relatively high, because if there is no strong sensitivity, it will not be able to reflect the water quality and flow in time.
5. Overload capacity
It is required that under certain working conditions, the assembly shall not be burnt or overheated, or there are many pits and contact adhesion.
Due to the particularity of the water flow indicator, in order to ensure that it can maintain good sensitivity during use, the technical requirements for it are relatively high. Only when these basic requirements are met can it be put into use, and only in this way can it ensure good performance requirements in the process of use.
