Abstract

The utility model relates to a single bar valve for regulating hot and cold water. The single bar valve for regulating hot and cold water is especially suitable for installing on a storage water heater to regulate the water temperature of feedwater, comprising a bar, a positioning ring, a valve cap, a sealing ring, and a four-way valve body. A valve core whose circumference is provided with an orifice and a throttling groove is arranged on the valve body, and the valve core connected with a control bar can do axial and/ or circumferential motion in the valve body. The orifice and the throttling groove on the valve core are partly communicated with the inlet on the valve body, or fully communicated, or not communicated controlled by the bar to regulate the proportion of the cold and hot water, and thereby, water temperature is regulated. The advantages of the utility model are that the operation is convenient; after water is stopped, when the single bar valve for regulating hot and cold water is opened again, water temperature does not need to be regulated again, so the single bar valve for regulating hot and cold water not only saves time, but also saves water.

Description

Single bar valve for mixing hot and cold water

The utility model relates to the control valve that a kind of chief of the Xiongnu in Acient China's handle is regulated hot and cold water, and particularly a kind of being applicable to is installed in the hot and cold water adjusting control valve of doing the adjusting of feedwater water temperature on the water-storage electric heater.

The feed valve that existing water-storage electric heater is used normally two handles Flow-rate adjustment water temperature and feed tank of controlling hot and cold water respectively discharges water, use not very convenient, regulate the water temperature troublesome poeration, particularly in use if need to suspend palpus throttle down in a moment, when opening again, still need regulate water temperature again, so not only time-consuming but also water wasting, operation is inconvenience especially.

The purpose of this utility model is exactly in order to overcome the shortcoming of above-mentioned prior art, designs a kind of water temperature of singlehandedly regulating, hot and cold water adjusting control valve easy to use.

This product comprises handle with novel formation, positioning ring, spool, valve basis, seal ring and valve gap, described valve body is the four-way structure, in spool is housed, have throttle orifice and throttling groove on the circumference of spool, have the paddle hole of hot and cold water on the valve body, the valve core housing that is connected with Joystick is loaded on to be done in the spool bore of valve body axially and/or circumferential movement, throttle orifice on the spool and throttling groove are controlled to be partly by handle with the paddle hole on the valve body and are communicated or all communicate or do not communicate, and the positioning ring of control spool rotation angle is equipped with in the joint of handle and spool rod end.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is a plan view of the present utility model;

Fig. 2 is a left pseudosection of the present utility model;

Fig. 3 is a top plan view of the present utility model.

1 handle among the figure, 2 positioning rings, 3 spools, 4 valve bodies, 5 seal rings, 6 valve gaps, 11 water inlets, 12 exit orifices, 13 water inlets, 14 osculums, 15 throttling grooves, 16 throttle orifices, 17 throttle orifices, 18 valve core through hole, 19 throttling grooves, 20 throttle orifices, 21 throttle orifices, are respectively the water port at a, b, c, d, e, f.

On the circumference of cylindrical spool 3, have four throttle orifices 16,17,20,21 and individual throttling groove 15,19, valve body 4 is the four-way structure, valve gap 6 is equipped with in the bottom of valve body, spool 3 is set in the spool bore of valve body, and with seal ring 5 sealing, the front end bar portion and the handle 1 of spool are fastenedly connected, and one positioning ring are housed to control the rotation angle of determining spool in the handle 1 and the joint of spool rod end.When the utility model be connected with the cool and hot water pipe interface of electric water heater be in user mode after, the handle 1 outside pulling that only needs to connect valve core rod portion can discharge water to water storage tank, and can be by any adjusting inflow of moving axially of handle, throttling groove 15 on the spool is connected with the little water port of a of valve body cold water inlet hole 11 at this moment, is flowed out from osculum 12 by the little water port of the c on valve body to enter water tank.The hot water of water tank forms warm water with cold water mix in valve body hot water inlet hole 13 flows to the valve body chamber.Throttle orifice 16 is with corresponding on the little water port of valve body hot water inlet hole 13 d and the spool.The b aperture of valve body cold water inlet hole 11 is corresponding with the throttle orifice 17 on the spool in addition, and hole 16 is into a pair of positive and negative afflux liquid resistance with hole 17, so, when the handle 1 that will connect valve core rod portion is done circumferentially to rotate by a direction, then hole 16 reduces with the relative cross-section of the little water port of d is long-pending, and hole 17 increases with the relative cross-section of the little water port of b is long-pending, so water temperature descends; Otherwise if when press other direction and rotating, then water temperature rises, and promptly changes the ratio of hot and cold water combined amount by the ratio that changes the resistance of afflux liquid, thereby the step-less adjustment of realization water temperature.Mixing warm water flows out from the little water port of e of shower nozzle osculum 14 through valve core through hole 18 and throttling groove 19 and throttle orifice 20.When not needing water, as long as handle 1 is promoted on earth inwards, can close, if when needing again water, as long as handle 1 outside pulling is promptly flowed out the water of identical water temperature when closing, if as long as with water handle 1 rotating certain angle, make a little water port connection of throttle orifice 21 and valve water inlet 11 on the spool when directly using cold water, through the hole 18 and the little water port of f emit cold water.

The utility model has the advantages that it is cold that handle just can be finished, the Adjustment operation of the open and close of hot water, flow and water temperature is convenient and simple, and suspends to reopen after the water and need not readjust water temperature. Not only saved time but also water-saving.

Claims

1, a kind of monolever hot and cold water adjusting control valve, comprise handle, positioning ring, spool, valve body, seal ring and valve gap, it is characterized in that being equipped with in the valve body of four-way on the circumference of spool spool and drive throttle orifice and throttling groove, have the paddle hole of hot and cold water on the valve body, the valve core housing that is connected with Joystick is loaded on to be done in the spool bore of valve body axially and/or circumferential movement, throttle orifice on the spool and throttling groove are controlled to be partly by handle with the paddle hole on the valve body and are communicated, and all communicate or do not communicate.
