Abstract
The utility model discloses a constant temperature spool which contains a valve handle, a pressure bolt, a buffer spring, a regulating bolt, a top cap, a filter net, a regulator, a heat-sensitive element and a valve body. The utility model is characterized in that the rod part of the heat-sensitive element is sheathed with a water mixer which is leaned against the head part of heat-sensitive element, a return spring is sleeved on the cylinder of the lower part of the water mixer, and the other end of the return spring is leaned against the inner boss of the valve body. A wear-resistant lubricating piece is arranged between the shoulder of the valve handle and the valve core body; the water mixer is in a trapezoid-column shape whose hollow space is provided with a plurality of ribs in uniform distribution, and a wear-resistant lubricating piece is arranged between the shoulder of the valve handle and the valve core body. The bound of the temperature-sensing area and the water mixing area is obvious, the cold water and the hot water are mixed uniformly, the heating of the heat-sensitive element is uniform, and the temperature-sensing performance is increased. The frictional force between the valve handle and the valve core body is reduced, and the service life is prolonged correspondingly.
Description
Technical field
The utility model relates to a kind of constant temperature plumbing, especially a kind of constant temperature valve core.
Background technique
The constant temperature valve core of mass selling on the present domestic and international market, as shown in Figure 1, constant temperature valve core is by valve rod, hold-down bolt, damping spring, adjusting bolt, top cap, valve core, spool, thermosensitive element, regulator etc., temperature zone and mixed zone do not have obviously and define, the hot water or cold water can not get abundant mixing, it is inhomogeneous that thereby the temperature-sensitive that makes thermosensitive element is heated, and causes the temperature-sensitive sensitivity poor.
Summary of the invention
The purpose of this utility model is: a kind of constant temperature valve core is provided, and not only the boundary of temperature zone and mixed zone is obvious for it, and the hot water or cold water fully mixes, and temperature-sensitive sensitivity height.
The utility model is achieved in that a kind of constant temperature valve core comprises valve rod, collar, hold-down bolt, damping spring, adjusting bolt, top cap, filter screen, regulator, thermosensitive element, valve core, valve body, its special way is: the head abuts that is set with water-water jet, water-water jet and thermosensitive element in the bar portion of thermosensitive element, Returnning spring is enclosed within on the cylinder of water-water jet lower end, the other end of Returnning spring be resisted against on the inner convex platform of valve body.
One wear-resisting lubricated sheet is arranged between the shoulder of valve rod and the valve core.
It is cylindrical that water-water jet is ladder, and some muscle evenly distribute in the hollow.
One " O " type circle is arranged on the outer peripheral surface of water-water jet.
Constant temperature valve core of the present utility model owing to increased a water-water jet, Returnning spring, makes temperature zone and mixed pool boundary obvious, and the hot water or cold water is mixed, and the temperature-sensitive of thermosensitive element is heated evenly, and has improved the temperature-sensitive performance; One wear-resisting lubricated sheet is arranged between the shoulder of valve rod and the valve core in addition, reduced the frictional force between valve rod and the valve core, corresponding increasing the service life.
