Simple instructions for the three-point operation test of the cartridge needle valve

Do you know how to operate the cartridge needle valve, below we look at the relevant instructions on the operation test of the cartridge needle valve. 1) For the test valve with a maximum allowable working pressure greater than 11 MPa at 20 degrees, the inlet pressure is maintained at the pressure specified in Table 2-8. For test valves with a maximum permissible working pressure of less than or equal to 11 MPa at 20 degrees, the inlet pressure is raised to the pressure specified in Tables 2-8. 2) Open the test cartridge needle valve to the full open position, and then close the globe valve 17, so that the pipeline and the test valve body cavity are connected. Record the maximum torque of the pneumatic ball valve required to operate the test valve. 3) The test cartridge needle valve is in the fully open position, and the external leakage of the test valve is detected and recorded under the pressure specified in Table 2-8, and the leakage detection duration is 5 minutes.

The use effect and standardized operation of the cartridge needle valve

How to ensure the use of the cartridge needle valve, in our use of the cartridge needle valve process, how to standardize the operation, below we look at the relevant instructions. The most important effect of the use of the cartridge needle valve is to make it achieve an effective cut-off and on effect, of which the cartridge needle valve is widely used in various pipeline management, its role plays an obvious advantage, there is also a good design for specificity, but its scientific standards, first-class technical content, and the quality of the valve itself also has a very important role. The standard operation service life of the cartridge needle valve is longer, which is a normative requirement for the establishment of the system of practical application, there is a system for the management of operation, the actual system of special management is guaranteed, which meets the needs of reality, and is also the most important product feature of the current very convenient application. The use of the cartridge needle valve is very extensive, to play a better role, the important role and significance of the pneumatic ball valve must also improve the cost performance of the product, the product quality and long service life, reasonable use, standardized operation, can play a very important role.

What are the specific types of instrument fittings?

Instrument fittings are used in the connection of pipes or control systems. Among them, the pipe fittings used for the change of pipeline direction, the branches of pipelines or the connection of pipes of different sizes are far more demanding than those of straight pipes, and the materials used in the pipe fittings of electric furnace fans can be pipes, plates, forgings, castings, rods and profiles. Processing can be used in welding, stamping, casting or forging methods. In general, the material and thickness of the pipe fittings depend on the material, shape, size, and other factors of the pipe fittings used, as well as the fluid medium and pressure being transported. Instrument fittings include tube fittings, welded fittings, flared fittings, threaded fittings, live fittings, a variety of automatic control instrument pipeline accessories, etc. It also includes YZG9-1 end welded rubber pipe fittings, YZG8-3 female threaded metal hose fittings, YZG8 metal hose fittings, YZG7-3 female thread tee joints, YZG7-2 female thread bending joints, YZG6-4 socket welded tee joints, YZG6-3 socket welding tee joints, YZG6-2 socket welding bending joints, YZG6-1 socket welding reducers, YZG7 series automatic control instrument pipeline accessories, etc.

How can I ensure that the ferrule fitting is sealed?

In the process of using the ferrule joint, its sealing is a very important performance, in the installation we need to do seal installation, then how can the sealing installation of the ferrule joint be carried out, let's look at the relevant instructions. To ensure that the fitting fittings are sealed, first cut the appropriate length of seamless steel pipe with a saw blade to remove the port burrs. Place nuts and fasteners on seamless steel pipes. Pay attention to the orientation of the nut and bite, do not install in reverse. The ferrule fittings lubricate the screws and sleeves of the pre-assembled fitting body, insert the steel pipe into the fitting body, and tighten the nut by hand. Tighten the nut until the tube jams the fermenter tube, and this turning point can be felt by the increase in the tightening torque. After reaching the pressure point, tighten the nut 1/2 turn. Remove the pre-assembled joint body and check the insertion of the ferrule cutting edge. Visible protruding straps fill the space at the front of the ferrule. It can turn slightly, but not axially. Next, when installing, the thread of the joint body should be lubricated during the actual installation, and the compression nut should be screwed together until the tightening force is felt, and then tighten the ring joint 1/2 turn to complete the installation.
