Description

A kind of New-type boiler water quality sampling cooler

A kind of New-type boiler water quality sampling cooler is made up of end socket, radiator coil tube, cylindrical shell, ring-type clamp structure, belongs to boiler applianee, is applicable to the water quality sampling of steam boiler and high-temperature-hot-water, and its bodily form is light and handy, novel structure, is convenient to maintenance, easy to use.

The feedwater of boiler must remove calcium, magnesium ion in anhydrating through softening, to prevent fouling in the operational process, influences heat transfer efficiency.Concerning steam boiler, in operational process along with the water in the boiler constantly evaporates, when staying total alkalinity in the boiler water and surpassing 26mmol/L, can cause serious alkaline corrosion to boiler, so in service at steam boiler, in order to control the concentration of alkali, must be to the regular sample examination of boiler water quality, will periodic blow down (bleeding off the water in a part of boiler) when exceeding standard, replenish new water then.Because the water temperature in the boiler is necessary by special equipment up to more than 100 ℃---the water quality sampling cooler, water quality temperature to be chemically examined is reduced to below 40 ℃.

The boiler water quality sampling cooler of Chu Shouing is the Vintage Product before five more than ten years in the market, its bodily form heaviness, and structure is outmoded, safeguards inconvenience.Disclose a kind of steam boiler water quality sampling cooler series on the product sample as Fengtai, Beijing boiler fitting factory, profile is that disk bottom of the cylindric spherical end is connected by ring flange with cylindrical shell, with 8 bolted, barrel diameter 200～250mm, high 400～450mm weighs 28～40kg, form with general steel plate weldering system, seem heavy, because of the boiler water quality sampling, no matter the boiler size, each needs 200 milliliters, the bodily form is so huge, and both waste material was impracticable again.

It is light and handy that the purpose of this utility model provides a kind of bodily form, and structure advanced person safeguards and use boiler water quality sampling cooler more easily.

For achieving the above object, boiler water quality sampling cooler of the present utility model is by end socket, radiator coil tube, cylindrical shell, the ring-type clamp structure is formed, the water inlet pipe and water outlet pipe of radiator coil tube all is welded on the end socket, fastening and the sealing by the ring-type clamp structure between end socket and the cylindrical shell, above it is characterized in that being welded with on the described end socket for having the ring flange of annular recess on below the inclined-plane, described radiator coil tube is shape in the shape of a spiral, described cylindrical shell is the spherical end, diameter 80～150mm, high 300～400mm, weigh 3～10kg, make of corrosion resistant plate (pipe), the top welding cooling water outlet pipe and the link plate of barrel, the below is welded with cooling water inlet pipe, be the inclined-plane below being welded with on the upper edge of barrel, above on have the ring flange of annular recess, O-ring seal is arranged between the ring flange, its upper and lower surface has annular projection, match with the groove on the ring flange, described ring-type clamp structure is made up of snap ring and wing bolt, and snap ring is made up of the arc clip of two to six band bag grooves, connects with hinge between the clip, snap ring has two free ends, free end with The shape member connects with hinge, Perforate on the vertical plane of shape member, wing bolt passes from the hole, and another free end of snap ring has the nest of a bottom of a pan shape, passes Behind the shape member, match with the termination of wing bolt, described hinge is made up of two web joints and two double end rivets, the termination of clip has two holes up and down, also there are two holes at the web joint two ends, two holes on the web joint and clip two holes up and down align, and the double end rivet passes two holes that align.

After having adopted said structure, because fastening between end socket and the cylindrical shell, finish by snap ring and wing bolt, by tightening wing bolt, bolt end produces thrust to the nest of the bottom of a pan shape, snap ring is tightened up, the bag groove of each clip presses two inclined-planes of ring flange, the vertical stress component that is produced compresses two ring flanges, make end socket and cylindrical shell fastening, the projection on the packing washer two sides between the ring flange also is pressed in the flange concave, plays sealing function, and is more convenient and labor-saving than traditional bolt fastening structure; Owing to adopted undersized stainless steel cylinder, make sampling cooler become attractive in appearance, light and handy, corrosion-resistant again.

The utility model compared with prior art has following advantage:

1. overcome that bolt fastening structure brings maintenance, awkward drawback in the prior art, its structure advanced person, safeguard easy to use.

2. overcome sampling cooler bodily form heaviness, corrosion-prone shortcoming in the prior art, its bodily form is light and handy, attractive in appearance, corrosion-resistant.

3. overcome the deficiency that skin is taken up an area of in the sampling cooler fixed installation in the prior art, it saves area, hanging position can change.
