Fully welded ball valve with extended rod is mainly used in the output pipelines, main lines and branch lines of large heating equipment such as HVAC pipeline centralized heating systems.
The biggest feature of the extended stem fully welded ball valve is that it has no leakage, is easy to operate and is safe. The fully welded ball valve is one of the main valves for HVAC pipelines developed and produced by Hebei Tongli Company.
Technical parameters of extended rod fully welded ball valve:
. Caliber is inch ()
. Pressure range =.
. Materials include carbon steel, stainless steel, two-way steel and other special alloys.
. Connection method: welding
. Specification: national standard
. Channel type: straight-through
. Working temperature: ℃&＋℃
. Customary medium: oil/gasoline, Liquefied natural gas/liquefied petroleum gas, petrochemical industry, steel plants, heating pipelines, etc.
. Operation method: handle, gear (vertical/horizontal), electric, turbine
Technical features of extended rod fully welded ball valve:
, the valve body can be adjusted according to the construction and planning requirements of the pipeline length and height of the valve stem.
The processing accuracy of the sphere is very fine, the operation is easy, and there is no bad interference.
.The valve body is welded using imported robots for seamless welding.
Use high-grade raw materials to ensure the above pressure.
Compared with the same standard products in the same industry, the valve body is small and beautiful in appearance.
The main application areas of extended rod fully welded ball valves are:
City gas: gas output pipelines, main lines and branch line supply pipelines, etc.
Centralized heating: output pipelines, main lines, and branch lines of large-scale heating equipment.
Heat exchanger: opening and closing of pipes and circuits.
Steel plant: various fluid pipelines, waste gas selective discharge pipelines, gas and heat supply pipelines, and fuel supply pipelines.
Various industrial equipment: various heat treatment pipelines, various industrial gas and thermal pipelines.
The overall design features of the fully welded ball valve with an extended stem:
The fully welded ball valve with an extended stem is completely manufactured according to the design and is fireproof and anti-static.
.The valve stem can be lengthened according to user's request.
.The flange connection in the middle of the valve body adopts bolt connection or welding connection B.
.The valve body, ball and other metal parts are all made of high-quality casting materials to ensure the quality and strength of the ball valve.
.The ball should be fixed with stuffing box or support plate. The stuffing box or support plate fixed ball can eliminate the bending moment of the valve stem caused by the force of the medium acting on the ball, so that the valve stem only accepts torque.
.The extended rod fully welded ball valve not only has this, but also has a low-conflict Teflon composite bearing fixed around the ball. The valve moves smoothly, the switching torque is small, and it is easy to operate.
.Sealing adopts two common soft seals and metal seals to form three seals. Ensure reliable sealing and safe use. Long life and no need for maintenance.
Characteristics of fully welded ball valve with extended rod:
Fully welded ball valve with extended rod will not cause external leakage.
Because the valve seat is composed of carbonized Teflon sealing rings and disc springs, it has strong adaptability to changes in pressure and temperature, and no leakage will occur within the marked pressure and temperature range.
The processing process of the extended rod fully welded ball valve is tracked and inspected by a leading computer inspection instrument, so the processing accuracy of the ball is high.
Because the valve body material of the extended rod fully welded ball valve is the same as the pipe material, there will be no uneven stress, nor will it be deformed due to earthquakes and vehicles passing over the ground, and the pipeline is resistant to aging.
The sealing ring body is made of R material with %b (carbon) content to ensure no leakage (%).
The extended rod fully welded ball valve can be buried directly underground. There is no need to build a high and large valve well. Only a small shallow well needs to be set up above the ground, which greatly saves construction costs and engineering time.
The processing accuracy of the sphere is very fine, the operation is easy, and there is no bad interference.
The use of high-end raw materials can ensure the above pressure.
Compared with the same standard products in the same industry, the valve body is small and beautiful in appearance.
Under the condition of ensuring the normal operation and use of the valve, the service life is more than one year.
