Abstract
The utility model discloses a silicon oil-carrying shunt valve element and mainly solves the functional and technical problem that the traditional shunt valve is susceptible to pollution by scale as well as aging and gradual sensitiveness loss in a short time and other functional and technical problems. The key points of the technical scheme of the utility model include: a cylindrical hollow inner cavity is arranged in the center of a valve element body (1); and a support (2) for mounting a temperature sensing rod is matched with and arranged in the hollow inner cavity of the valve element body (1) to separate hot water from cold water. The cylindrical external wall of the support (2) is in clearance fit with the wall of the hollow inner cavity of the valve element body (1); two or more annual grooves (4) are arranged on the cylindrical external wall of the support (2); and a sealing ring (11) is sleeved in each annual groove (4). Silicon oil can be applied on the wall of the inner cavity of the valve element body between the sealing rings (11) and a gap (8) on the support and filled in the hollow inner cavity of the valve element body (1). And the silicon oil gradually seeps out to form a layer of oil film to protect the sealing rings (11), the surface of the inner cavity of the valve element body (1) and the surface of the support (2) against pollution by scale, so the functional life of the shunt valve element is prolonged.
Description
Technical field
The utility model relates to a kind of shunt valve core.
Background technique
At present, the sealing configuration effect that is used for the shunt valve core is not fine or the structure more complicated, and existing shunt valve will be polluted, wear out, lose gradually sensitivity by incrustation scale in the short time in 1 to 2 year.Apply for " a kind of multi-valve type water tap sealing adjusts the water valve core " (application number: 200420054535.9 of utility model patent on December 15th, 2004 as the Zhu Qilong of Zhu Cun behind the Rui'an City Bao Tian Town, Zhejiang Province, notice of authorization day: on May 10th, 2006), it includes shell, controlling rod, water diversion disk and with water diversion disk close-fitting water inlet and outlet chassis and seal disc, be provided with containing groove in the described seal disc, be provided with corresponding with it seal ring in the groove, the water inlet and outlet chassis be provided with seal disc in the boss of containing groove corresponding matching, described water inlet and outlet chassis cooperates with the seal disc tight seal by seal ring.And for example Tongan City, Xiamen City, Fujian Province five shows the Lv Qingqing of four woods industrial regions, town in " the silica gel group structure of ceramic sealing spool " (application number: 200520057728.4 of application on April 25th, 2005 utility model patent, notice of authorization day: on October 25th, 2006, notification number: 2830820), it is that the silica gel group is installed in the valve seat, be positioned at the below of ceramic plate, the silica gel group is assembled by silica gel circle and copper sleeve ring, forms groove on the inwall of silica gel circle, and copper sleeve ring is assembled in this groove.Its structure more complicated, effect is not good enough yet.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, good sealing effect and lower-cost siliceous oil type shunt valve core.
The technological scheme that its technical problem that solves the utility model adopts is: the central authorities of spool body 1 are the cylindrical shape hollow lumen, the supporting base 2 that is used to install temperature-sensing rod cooperates and is installed in the hollow lumen of spool body 1, the cylindrical outer wall of supporting base 2 becomes Spielpassung with spool body 1 hollow lumen wall, and at the annular groove of establishing on the cylindrical outer wall of supporting base 2 more than 2 or 24, and in annular groove 4, be set with seal ring 11.The elastic seal ring that described seal ring 11 also can adopt flexible material to make.
The utility model also can scribble silicone oil at the spool chamber body wall between the seal ring 11 between cylindrical outer wall that is installed in supporting base 2 and the spool body 1 hollow lumen wall and 8 places, space of supporting base.
The utility model also makes external diameter between the annular groove 4 of supporting base 2 cylindrical outer wall less than the external diameter at supporting base 2 two ends, but greater than the diameter of annular groove 4 bottoms.
The beneficial effects of the utility model are: it is by adopting the dual more stable work that makes the shunt valve core to multi-sealed structure.And can pass through filling silicon oil, protection seal ring, spool chamber body surface, and the supporting base surface can not polluted by incrustation scale, reach the purpose that functional lifetime prolongs.It is simple in structure, good sealing effect and cost are lower.
