Definitions
- the present invention relates to fluid treatment, in particular to apparatus for use in straining fluid in fluid piping, for example fluid in fluid circuit piping of a heating system or a cooling system.
- Known heating and cooling systems comprise a fluid circuit through which a fluid circulates under pressure.
- An example of this type of system is a closed circuit central heating system, in which system water flows in a loop from a boiler, through a series of radiators or heat emitters, and then back to the boiler.
- Systems of this type are typically manufactured from steel and other common metals. In such systems, material surfaces are exposed to the circulated fluid. A problem that is commonly associated that these systems is the corrosion of metal that is in contact with the system fluid.
- a known device for use in removing corrosion particles from the circulating fluid is a strainer (also termed a pipeline strainer).
- the strainer is connected to the fluid circuit piping, directly in-line with the fluid flow, and functions to mechanically remove unwanted solids from the system fluid.
- fluid flows through a screen within the strainer, which acts as a physical filter. Particles in the system fluid that are over a certain size are trapped by the screen, and captured particles are retained within the strainer for subsequent removal.
- Strainers are typically installed upstream of equipment to be protected.
- a strainer may be installed upstream of a pump to prevent larger pieces of debris from fouling the impeller, which could result in a blockage or damage.
- a strainer may be used upstream of a boiler, a heat exchanger, or a large and/or expensive item in a system.
- a type of prior art strainer is known as a Y-type strainer.
- the body of a Y-type strainer has first and second branches providing an inlet and an outlet, and a third intermediate branch providing a pocket for a screen that intersects the fluid flow path between the inlet and outlet, such that fluid flowing through the body passes through the screen.
- the screen is typically provided by a strainer basket, which takes the form of a cylindrical drum made from a metal perforated sheet or mesh.
- a strainer basket which takes the form of a cylindrical drum made from a metal perforated sheet or mesh.
- fluid flows into an open end of the cylindrical screen and any particles that are too big to flow through the openings, such as rust and detritus particles, are trapped inside for subsequent removal. In this way, contaminant particles over a certain size are separated from the circulating fluid as it flows through the strainer. Over time, however, the particles captured within the cylindrical screen build up and inhibit throughflow. To prevent problems arising from clogging or blocking of the screen by caught particles, routine maintenance is required to remove the collected detritus from within the strainer. However, unlike some filters, the screen can be cleaned and reused.
- a typical screen has openings dimensioned to prevent passage therethrough of particles having a particle size equal to or greater than 80 microns. Therefore, particles having a particle size of less than 80 microns are not prevented from flowing through the strainer and back into circulation. It is known for these smaller particles to settle in‘low flow’ areas, for example at the bottom of radiators and pipes of a heating system. Further, it is known for rust particles, which are relatively very small, to combine with scale deposits to form a sludge-like substance (generally termed sludge). This is particularly prevalent in areas of particle settlement. Sludge is a common problem within heating systems, and can block pipework and develop into large clumps in the bottom of radiators. Sludge deposits or clumps at the lower end of a radiator cause a localised reduction in heat transmission (known in the industry as a cold spot). The presence of such cold spots increases energy usage and places the system under operational strain. Summary of the Invention

Further, during normal operation of the strainer 101 , magnetic particles are attracted by the accessory 501 and collect within the interior chamber 103.
- Magnetic particles having a particle size equal to or greater than the predetermined size collect within the screen collector 201 only; magnetic particles having a particle size less than the predetermined size may collect within the screen collector 201 (for example, against the inside wall surface thereof) or against an internal wall surface of the third branch I 10 of the Y-shaped body 102. These captured particles are retained in the interior chamber 103 until subsequently removed.
- the strainer 101 is isolated from the fluid flow to stop circulation of fluid into the strainer 101.
- Accessory 501 is removed from around the branch I 10 housing the screen collector 201 , to remove the magnetic field previously applied by the permanent magnet arrangement of the accessory 501.
- the collector port 107 is opened to allow removal of the screen collector 201 from within the body 102.
- the screen collector 201 is withdrawn through the collector port 107 and rinsed clean of captured magnetic and non-magnetic particles.
- the internal wall surfaces of the third branch I 10 of the body are rinsed clean of captured magnetic particles.

- each adjustable permanent magnet 803, 804 comprises an external screw thread, such as external screw thread 81 1 of adjustable permanent magnet 804, that is co-operable with an internal screw thread (not shown) of a respective aperture, such as aperture 808, of the collar 802 to movably support the adjustable permanent magnet inside the collar 802, the adjustable permanent magnet 803, 804 rotatable within the respective aperture 807, 808 to vary the extent of insertion of the adjustable permanent magnet 803, 804 inside the collar 802.
- the collar 801 is shown in an‘at rest’ condition, in which the collar 802 has an internal diameter 812.
- collar 801 is usable on pipeline strainer 101.
- each of the adjustable permanent magnets 803, 804 comprises an engagement arrangement, such as engagement arrangement 1001 of adjustable permanent magnet 803, that is co-operable with a tool, such as tool 1002, for facilitating rotation of the permanent magnet 803, 804 within the respective aperture 807, 808.
