Forged steel globe valve J11H

Globe valve is a valve that closes the valve (disc) along the centerline of the valve seat. According to the valve flap in this form of movement, the valve seat through the mouth of the change is proportional to the disc stroke.

Because of the valve stem to open or close the trip is relatively short, but very reliable cut off function, and because changes in the valve seat and the valve stroke is proportional, is very suitable for flow regulation. Therefore, this type of valve is very suitable for cutting or regulation and throttle use.

The selection principle is: 1, high temperature, high pressure medium pipeline or device should be used to stop valve. Fire power plants, nuclear power plants, high temperature and high pressure pipeline in petrochemical system. 2, the pipeline on the convection resistance requirements on the pipeline. The pressure loss is not considered. 3, small needle valve can be used, instrument valves, sampling valves, pressure gauge valve. 4, a flow control or pressure regulation, but regulation accuracy is not high, but also the relatively small diameter pipes, such as the nominal pipe by less than 50mm, should be selected. 5, synthetic industrial production of small chemical fertilizer and large chemical fertilizer should be selected nominal pressure PN160 nominal pressure 16MPa or PN320 nominal pressure 32MPa high angle angle valve or high angle throttle valve. Line 6, Bayer alumina production desiliconization workshop, easy to coke, easy to use separate valve type hard alloy, can place the seat, sealing DC or DC type throttle valve. 7, in the construction of city water supply, heating engineering, nominal pipe by small, can use cut-off, balancing valve or piston valve, such as nominal by less than 150mm of the pipeline.

Forged steel valve to pay attention to the valve in the switch position. Ball valve maintenance is generally in the open state, under special circumstances, choose to close the maintenance. Other valves can not be punished in order to open spaces. Forged steel valve in the conservation must be in a closed state, to ensure that the grease seal ring along the sealing groove, if opened, the seal grease directly into the flow channel or cavity, resulting in waste. Valve grease, often ignore the effect of grease. The pressure of the grease injection, the amount of grease and the switch position are normal. However, in order to ensure the effect of the valve grease, and sometimes need to open or close the valve to check the effect of lubrication, valve valve ball or gate surface to ensure uniform lubrication.
