Abstract

The utility model discloses a temperature adjustable water valve for solving the problem of the inconvenient linkage between the switch of the valve and the adjustment of the water temperature. The water temperature adjusting mechanism and the switch mechanism of the valve are in the separate type. A valve body with a central hole, a sliding sleeve, a screwed sleeve and a valve core sleeve are installed inside a valve base connected with a water inlet pipe and a water outlet pipe for the cold and hot water from outside to inside in turn. The side wall of the valve body central hole is provided with an upper and a lower side holes with different height respectively communicated with the water inlet pipe for the cold and hot water. The lower part of the sliding sleeve inside the valve body central hole is provided with a through hole. The screwed sleeve is screwed on the outer screw on the sliding sleeve; the inner tooth on the valve core sleeve can be engaged with the outer tooth of the screwed sleeve; a water mixing hole is arranged in the lower rod of the valve core sleeve. A handle is hinged with the valve core sleeve; the center of the valve core sleeve is provided with a switch rod. When the handle is pressed down and rotated, the sliding sleeve moves up and down, and the water feeding mixtureratio of the cold and hot water can be altered. When the handle is raised, the switch rod is driven to open the water mixing hole, and the cold and hot water can flow out; the adjustment is sensitive, accurate and convenient.

Description

But Temp.-controlled water valve

Technical field

The utility model belongs to daily necessities, and specifically a kind of and hot and cold two kinds of water sources are connected, by the staff operating grip, and the water temperature of control water outlet and the water valve of water-outlet quantity size.

Background technique

Present adjustable temperature water valve is used for changing and makes the water temperature of water very convenient.Above-mentioned water valve is connected with cold and hot two kinds of water sources, mostly is to make it movable in three dimensional space by handle with sleeve, controls the water temperature and the water-outlet quantity size of water outlet.Its structure is, have in the bottom of handle an end can with the driving lever of handle interlock, the hole that driving lever is worn with valve seat top in the middle part of driving lever is a fulcrum, coupled moving up-hole plate rotation angle or dislocation can be stirred in the bottom of driving lever, the hot water or cold water water inlet of the fixedly orifice plate that is connected with intake pipe and the size of osculum are changed, the inflow of hot and cold water and water-outlet quantity what are controlled.In use find: above-mentioned water valve one is the yardstick bad grasp of handle with sleeve when making driving lever stir up-hole plate corner or dislocation, therefore regulates insensitively, needs repetition test just can mix up; The 2nd, because the switch of water valve and the adjusting of water temperature link, when opening water valve handle water, bumping handle because of carelessness askew will change the angle of handle, water temperature, the water yield are changed, be easy to cause hot water scald or cold water to hit flu to the people, this water valve especially is not suitable for the not strong children of control ability and the old man uses.

The model utility content

Technical problem to be solved in the utility model is to overcome in the Temp.-controlled water valve prior art, the switch of water valve and the adjusting of water temperature link, run into the angle that handle will change handle because of carelessness, the change water temperature and the water yield that do not conform to people's wish, but and above-mentioned water valve regulate a kind of Temp.-controlled water valve that shortcoming such as insensitive provides.

In order to solve the technical problem that above-mentioned water valve exists, the utility model is to adopt following technical proposals to realize: the water temperature controlling mechanism of water temperature modulating valve and the switching mechanism of water valve are separated type:

The composition of water temperature controlling mechanism is, in being connected with the water valve valve seat of hot water or cold water's intake pipe and outlet pipe, the valve body of band center hole is installed, on the sidewall of valve body center hole bottom, be provided with two different water inlet upper-side hole and lower-side holes that also communicate with hot water or cold water's intake pipe on the valve seat respectively of height; On the top of valve body center hole the sliding sleeve that slides up and down only is installed, the top of sliding sleeve is provided with is with externally threaded step, and horizontal through hole is located to be provided with in the sliding sleeve bottom in the valve body center hole; Thread bush is enclosed within on the axle journal on valve body top rotationally, and the internal thread of thread bush is screwed on the outside thread of above-mentioned sliding sleeve, and its periphery is provided with vertical tiny external tooth; Valve core housing can slide up and down to be inserted in the sliding sleeve center hole, is provided with the internal tooth that can be meshed with the external tooth of thread bush in the cap on valve core housing top, and the lower beam of spool sleeved rod portion is provided with horizontal mixed water hole; In the cap on valve core housing and between the thread bush top pressure spring is installed; The seat that is buckled in the handle at valve seat top is connected with the top hinge of valve core housing;

The switching mechanism of water valve is, elongated switch lever can slide up and down to be installed in the center hole of valve core housing, can block or open mixed water hole when sliding up and down, and a seat inner top that is buckled in the handle at valve seat top is connected with the top movable of switch lever.

To enter hot and cold in the valve and before flowing out outlet pipe, evenly mix in order to make, between the lower beam border of described valve core housing and the through hole on the sliding sleeve, can be provided with mixed water cavity;

For the water-outlet quantity of energy trace adjusting Temp.-controlled water valve, the lower end surface of described switch lever can make inverted cone.

When using Temp.-controlled water valve to need temperature adjustment, handle is pressed down the drive valve core housing to glide, internal tooth on its cap is meshed with external tooth on the thread bush, handle with sleeve, driving thread bush trackslips on the top of valve body, the sliding sleeve that is threaded with it is moved up and down, and the water inlet upper-side hole of the through hole subtend valve body of sliding sleeve bottom and the openings of sizes of lower-side hole will change, that is have changed the water inlet proportioning of cold water and hot water; After the adjustment of finishing side opening openings of sizes up and down, carry on release handle and the hand grip portion handle, drive to move on the switch lever mixed water hole is opened, cold water and hot water can be entered by its intake pipe respectively, enter osculum by the side opening up and down on the valve seat, the through hole on the sliding sleeve, the mixed water hole on the valve core housing, flow out from outlet pipe again and use for the people.For can make the people feel the height of institute's temperature adjustment degree at short notice, can press down, rotate at seat with handle regulate water temperature in, hand grip portion is upwards lifted, this moment, opening with temperature adjustment of water valve can be carried out simultaneously.

When the lower end of switch lever was inverted cone, the height of the hand grip portion of handle in the control can make the aperture of mixing the water hole regulate in little scope once more.

The advantage and the effect of above-mentioned Temp.-controlled water valve are that because the openings of sizes of cold water and water inlet of hot water is directly actuated with screw thread, it is high and sensitive therefore to adjust validity; In addition because the adjusting of the switch of water valve and water temperature is two independent cover mechanisms, after water temperature regulates, handle lifts automatically under the effect of spring with thermoregulative mechanism and breaks away from, handle changes in any case, water temperature is changed, the water people can not occur and suffer the phenomenon that hot water scalds or cold water hits, the people who is fit to any age bracket uses.
