Description
Technical Field
The utility model relates to a fire-fighting equipment especially relates to an outer pressure storage relief pressure valve spring opening force testing arrangement.
Background
Different from the traditional internal pressure storage type heptafluoropropane fire extinguishing system, the external pressure storage type heptafluoropropane fire extinguishing system has two types of 4.2MPa and 5.6MPa, the high-pressure power gas pressure for conveying the fire extinguishing agent reaches more than 13MPa, the high-pressure power gas is separately stored in a special power gas bottle, the high-pressure gas is released after the system is started, and the high-pressure gas enters a fire extinguishing agent bottle group after being decompressed by a decompressor, so that the fire extinguishing agent is pushed to reach a protection area through a fire extinguishing agent conveying pipeline to extinguish fire. Compared with the internal pressure storage type heptafluoropropane, the external pressure storage type heptafluoropropane fire extinguishing system has the following advantages: the fire extinguishing agent conveying distance is greatly increased, and the fire extinguishing agent is more suitable for long-distance conveying and large-space protection areas; the pipe diameter of the conveying pipeline is small, so that the investment cost is saved; the pressure of the nozzle at the tail end of the pipeline is higher, the atomization effect of the fire extinguishing agent is improved, the spraying time is shortened, and the fire extinguishing efficiency is improved. The external pressure storage type heptafluoropropane fire extinguishing system adopts a pressure reducing valve, has the functions of constant pressure, pressure stabilization and overpressure prevention, can open the container valve of the fire extinguishing agent bottle group after the set pressure is reached, and can make the power system output at constant pressure and pressure stabilization within a certain time, so that the power gas can be maximally utilized.
The external pressure storage pressure reducing valve has many advantages, the opening force of the valve is the most difficult to adjust, the opening force of the valve is realized by adjusting the spring in the valve, the spring has larger difference due to different materials, processing techniques and production personnel, if the spring is directly installed in the pressure reducing valve, the opening force of the pressure reducing valve cannot be accurately known, the designed output pressure cannot be reached, the functions of constant pressure and overpressure prevention are difficult to realize, and the safety of personnel and equipment cannot be guaranteed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the not enough of prior art, provide a simple structure, convenient to use, efficient outer pressure storage relief pressure valve spring opening force testing arrangement.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides an outer pressure storage relief pressure valve spring opening power testing arrangement, includes the frame, be equipped with pressure sensor, test screw and display on the frame, pressure sensor with test screw mutual disposition, the specification of test screw is unanimous with the pressure regulating screw in the outer pressure storage relief pressure valve, and the one end that the test screw is close to pressure sensor is equipped with the spring briquetting, the display with pressure sensor links to each other.
As a further improvement of the above technical solution: the spring pressing block is connected with the testing screw rod through threads.
As a further improvement of the above technical solution: the precision of the pressure sensor is 0.05%, and the measuring range is 0-700 kg.
Compared with the prior art, the utility model has the advantages of: the utility model discloses an outer pressure storage relief pressure valve spring opening force testing arrangement, relative arrangement spring briquetting and pressure sensor on the frame, arrange the spring between spring briquetting and pressure sensor can, the spring briquetting moves one side at place to pressure sensor through the test screw rod and removes compression spring, pressure sensor's pressure transfer is to on the display, when the pressure that the display shows reaches the target value, note the rotatory number of turns of test screw rod, when mounting the spring to the relief pressure valve, can with the rotatory same number of turns of the pressure regulating screw rod in the relief pressure valve, thereby can make the spring reach the opening force of design fast and accurately, shorten the required time of production greatly, guarantee the safety of personnel and equipment.
