Q46F four-way valve
Summary of Q46F four-way valve.
Q46F four-way valve in the oil, natural gas, coal and ore mining, refining processing and pipeline system;In chemical products, medicine and food production;In hydropower, thermal power and nuclear power production system;In urban and industrial water supply and drainage, heating and gas supply system;In the farmland irrigation and drainage systems;Widely used in metallurgical production system, is a kind of related to production and construction, national defense construction and people's life important mechanical products.Ball valve closed in all kinds of pipeline system used to truncate or through media flow, make the medium in accordance with the procedures scheduled delivery to the specified point.
Q46f four-way valve characteristics and advantagesPart 1, manual handle can be made of steel or stainless steel casting handle.Handle sets limit structure, set in the position of the valve open and close limit, when the valve is used in the key device, the spacing block has a lock can lock switch position to avoid wrong operation.Handle has obviously and off.
2, the valve stem a182f (1 cr13) integral forging processing and modulation, hardness of hb220 ~ 250.Stem through key spline or the parties connected to the handle, strong commonality, easy tear open outfit.Stem with blow-out proof design.
3, valve filling knitting, flexible graphite sealing ring or ptfe seals, lubrication situation of the stem in a reliable seal.
4, according to the needs, the ball valve can be designed as antistatic structure, in the sphere and valve stem, valve stem and valve body between the conductive spring, avoid electrostatic spark to ignite flammable material, ensure the security of the system.
5, sealing deputy various forms.According to the different condition can choose soft seal and hard seal, such as fire seat structure;6 the following for floating ball form, dn200 for fixed ball form below.
6, ball valve seat in auxiliary seal structure can be set up, in the seat and the valve stem parts add fat injection valve, an emergency can be temporarily seal, and according to need to lengthen the valve stem to appropriate buried laying venues
Q46f four-way valve structure characteristics
The four-way reversing valve, a valve switch direction to water supply, each turn 90, water supply way switch once, before four valves, water supply 1, 4, open the valve, the valve closed 2, 3,Reverse when the water supply valve, 2, 3, open valve closed 1, 4, (figure 1), now with a four-way ball valve (figure 2) alternative, easy to operate.
