Background technique
Double-U-head is the vitals of earth-source hot-pump system.Earth-source hot-pump system is derived from Europe, is a kind of energy-conservation heating or refrigeration system, greenhouse gases (as C02) discharge amount can be reduced to 0%.In Europe, earth-source hot-pump system is mainly used in private apartment and house, and heat load is lower.Therefore Europe generally adopts the U-shaped Buried heat exchanger of list that heat load is lower.The construction cost of earth-source hot-pump system is very high, and in order to make construction cost more economical, very important aspect is the size reducing drilling well.In China, the situation of earth-source hot-pump system is different, and be mainly used in the heavy constructions such as hotel, large supermarket and exhibition center, heat load is very high.Therefore, in China, heating or refrigeration Designer can design Double-U-shaped buried heat exchanger usually.Double-U-shaped buried heat exchanger is compared with single U-shaped Buried heat exchanger, and heat exchange efficiency can improve a lot, and nearly 70%.In order to control the cost of drilling well, earth-source hot-pump system drilling well small-sized, for singly U-shaped Buried heat exchanger and Double-U-shaped buried heat exchanger are all similar, therefore for current Double-U-shaped buried heat exchanger, due to spatial constraints, the installation of Double-U-head and tubing is also very difficult, in a lot of situation, has to adopt special soldering appliance.Because the size restrictions of drilling well, cause penetration resistance in double-H groove weld Buried heat exchanger work progress comparatively large, contain more grit in some Soils In The Region in addition, easily damage Double-U-head and tubing joint.
Such as, Chinese patent literature discloses a kind of Double-U-head pipe fitting for ground source heat pump [application number: 201120295798.9], includes the pipe fitting of plug-type, and pipe fitting top is provided with two groups of inserting columns, often organize inserting column and include two inserting columns, in each inserting column, be equipped with jack; Be provided with water port in described pipe fitting, each jack is all communicated with water port.
Although such scheme space is comparatively large, do not affect water flow, still there is design reasonable not, be not easy to buried installation, install and be loaded down with trivial detailsly easy to the technical problems such as damage.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, is convenient to the Double-U-head assembly installed.
For achieving the above object, the utility model have employed following technical proposal: this improved type Double-U-head assembly, it is characterized in that, comprise the body in column, described body is provided with two U, pipe joint is respectively equipped with at the two ends of U, the one end described body being positioned at pipe joint is provided with open at both ends and cover body in hollow tube-shape, the circular groove that the one end described body being positioned at pipe joint offers, described circular groove is set in two U peripheries, described cover body the inner to be arranged in circular groove and to be connected with body by demountable structure, described cover body outer end is provided with for closing this end and the disk body of energy circumference rotation, described disk body offers four rodding eyes that can pass for body, described body is provided with conically positioning part away from one end of U, the attachment hole being connected and fixed device is provided with in outer end, positioning part.
In above-mentioned improved type Double-U-head assembly, in described circular groove, be provided with the first screw thread, described cover body the inner be provided with can with the second screw thread of the first screw-thread fit.
In above-mentioned improved type Double-U-head assembly, described cover body outer end inner wall offers annular groove, described disk body outer part is provided with the annular convex that can coordinate with annular groove.
In above-mentioned improved type Double-U-head assembly, in described rodding eye, be provided with the first seal ring.
In above-mentioned improved type Double-U-head assembly, be provided with convex metal nut in described attachment hole, the axial length of described convex metal nut is less than the degree of depth of attachment hole, and described convex metal nut the inner is resisted against attachment hole the inner.
In above-mentioned improved type Double-U-head assembly, the attachment hole inwall of described convex metal nut outer end is provided with the second seal ring.
Compared with prior art, the advantage of this improved type Double-U-head assembly is: 1, reasonable in design, is convenient to install.2, the pipe joint on sandstone damage Double-U-head is effectively prevented.3, good airproof performance, further strengthens protective.4, location is convenient, reliable, reduces installation difficulty, ensure that installation quality.5, sound construction, long service life.
