Magnetic locking elastic seat sealing gate valve

Magnetic locking elastic seat seal gate valve is a widely used valve, which is popular because the friction between the sealing surfaces is small during the opening and closing process, the opening height is not large, the manufacturing is easy, and the maintenance is convenient. It is not only suitable for medium and low pressure, but also for high pressure. Its closing principle is to rely on the pressure of the valve stem to tightly fit the sealing surface of the valve disc with the sealing surface of the valve seat, preventing the flow of the medium

Magnetic locking elastic seat sealing gate valve is a type of valve that adds a magnetic lock to the original foundation. It is used in heating, water supply and other charging pipelines, and can stop water and heat supply to users at any time to prevent losses caused by intentional water and heat fees arrears. Installing this magnetic password locking elastic seat seal gate valve on important pipeline systems or equipment can prevent accidents caused by non operators accidentally opening or closing the valve

The magnetic locking elastic seat seal gate valve adopts the popular casting material ductile iron, which creates a locking gate valve with good toughness. The locking gate valve screw is made of 2Cr13 stainless steel material, and the valve appearance is coated with epoxy resin technology. The anti-theft locking valve has the advantage of encrypted anti-theft function, preventing internal and external personnel from intentionally opening and closing the valve, causing resource loss and accidents. Magnetic locking elastic seat sealing gate valves are widely used in water supply and heating charging pipelines, which can stop water and heat supply to users at any time, preventing losses caused by intentional arrears of water and heat fees by users

Magnetic locking elastic seat sealing gate valve only allows one-way flow of medium and has directionality during installation. Its structural length is greater than that of a gate valve, and at the same time, it has high fluid resistance. During long-term operation, its sealing performance is not strong

Magnetic locking elastic seat seal gate valves are divided into three categories: straight through, right angle, and DC inclined globe valves

When the magnetic locking elastic seat seal gate valve is opened, the opening height of the valve disc is 25% to 30% of the nominal diameter. When the flow rate has reached a large level, it indicates that the valve has reached the fully open position. Therefore, the fully open position of the globe valve should be determined by the stroke of the valve disc

The bottom of the magnetic locking elastic seat sealing gate valve adopts the same flat bottom valve seat design as the water pipe, which does not produce debris accumulation, has a small flow resistance coefficient, and a smooth channel. The magnetic locking elastic seat sealing gate valve body is coated with epoxy resin inside and outside to prevent corrosion and rust. It can not only be used for domestic water, but also in sewage treatment systems. Widely used as regulating and throttling devices on fluid pipelines such as tap water, sewage, construction, petrochemicals, food, medicine, textiles, electricity, ships, metallurgical energy systems, etc

The opening and closing component of the magnetic locking elastic seat seal gate valve is a plug shaped valve disc, with a flat or conical sealing surface, and the valve disc moves linearly along the centerline of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem is lifted and lowered without the handwheel lifting), as well as a lifting rotating rod type (the handwheel rotates and lifts together with the valve stem, and the nut is set on the valve body). The bellows globe valve is only suitable for fully open and fully closed, and is not allowed to be adjusted or throttled

Magnetic locking elastic seat sealing gate valve belongs to the forced sealing type valve, so when the valve is closed, pressure is applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve body from below the valve disc, the resistance that the operating force needs to overcome is the frictional force between the valve stem and the packing, as well as the thrust generated by the pressure of the medium. The force required to close the valve is greater than the force required to open it, so the diameter of the valve stem should be larger, otherwise the valve stem bending fault may occur. In recent years, with the emergence of self sealing valves, the flow of medium in shut-off valves has shifted from above the valve disc into the valve chamber. Under the pressure of the medium, the force required to close the valve is small, while the force required to open the valve is large, resulting in a corresponding reduction in the diameter of the valve stem. Meanwhile, under the influence of the medium, this type of valve is also relatively tight. The "Three Modernizations" of valves in our country once stipulated that the flow direction of globe valves should be from top to bottom

Advantages of magnetic locking elastic seat seal gate valve:

1、 The structure is simple, and manufacturing and maintenance are relatively convenient

2、 Small work schedule and short opening and closing time

3、 Good sealing performance, low friction between sealing surfaces, and long service life

The types of magnetic locking elastic seat seal gate valves are divided into external thread type and internal thread type according to the position of the valve stem thread. According to the flow direction of the medium, there are straight through, direct current, and angular types. Globe valves are classified according to their sealing forms, including packing bellows gate valves and bellows sealed globe valves

Installation and maintenance of magnetic locking elastic seat sealing gate valve:

1、 The bellows globe valve operated by handwheel and handle can be installed at any position in the pipeline

2、 Handwheels, handles, and dynamic mechanisms are not allowed for lifting purposes

3、 The flow direction of the medium should be consistent with the arrow direction shown on the valve body

Performance characteristics of magnetic locking soft seal gate valve:

1、 The overall rubber coated valve core is made of ductile iron skeleton, with stable performance rubber and new vulcanization technology used for overall coating inside and outside, tightly and firmly fitting, with sealing elasticity, achieving zero leakage

2、 Adopting a three way "O" - shaped sealing ring design, it has the characteristics of tight sealing, significantly reduced friction resistance, environmental friendliness and hygiene, and can replace the "O" - shaped rubber ring even under pressure without stopping water

3、 The inner and outer surfaces of the valve body are coated with epoxy resin, and the internal components are made of stainless steel and copper alloy to prevent rust and fluid corrosion. Can be directly used for domestic water and pharmaceutical industries
