Abstract

The utility model relates to a valve for mixing fluids, which is composed of a valve body, a valve bottom, a valve core, a handle, a valve cover and sealing parts. The valve body is provided with a cool water mouth, a hot water mouth and a mixed water mouth in different heights. The central part of the valve core is provided with a ring water inlet groove and a hole which are communicated with the cool water mouth, the hot water mouth and the mixed water mouth. The purpose of optionally controlling the proportion of two fluids and the temperature of outlet water under the situation of not changing the quantity of the outlet water can be achieved by rotating the handle. The utility model has the advantages of simple structure, convenient operation, stable temperature of the outlet water, etc.

Description

Temp. control valve by mixing hot-water with cold-water

The utility model relates to a kind of device of fluid-mixing, and is especially relevant with mixing valve for cold and hot water.

Washbowl in the lavatory, bathtub, shower all are to finish by regulating two valves that are contained in respectively on the hot and cold water pipe with the control of hot and cold water at present.Not only expense is higher for this method, maintenance and installation man-hour is many but also mixed water temperature instability, need to increase or must readjust water temperature again when reducing the water yield.Researched and developed the valve of various structures for this reason.Wherein there is a kind of fluid mixing valve only need use a valve just hot and cold water can be mixed into temperature required hot water, changes with water temperature, can not under the constant situation of the water yield, regulate water temperature on demand but its deficiency is the water yield.Disclosed combustion taps among the CN87212594, it is by valve body, spool, valve gap, handwheel, temperature adjustment handle, cold water hole, hot water hole, mixing water hole, and black box is formed.Though this tap can be implemented in the required water temperature of adjusting under the constant situation of the water yield, but to successively operate two handles when using, and, therefore in use touch the position that the temperature adjustment handle then very easily changes the temperature adjustment handle accidentally water-exit temperature is changed because the mode that adopts the temperature adjustment handle to rotate in the handle rotation slot realizes regulating water temperature.

The purpose of this utility model is at the problem that exists in the prior art, designs valve of a kind of usefulness, and only needing to operate a handle just can be convenient and reliable, regulates freely the hot and cold water heat control valve that the water yield does not change with water temperature.

The hot and cold water heat control valve of the utility model design is by valve body 1, and at the bottom of the valve 2, spool 3, handle 4, valve gap 5 and some Sealings are formed.On the different heights of valve body and different direction cold water hole 6 is arranged respectively, hot water hole 7 and mix water hole 8 mixes water hole 8 in extreme lower position.2 have water space 9 at the bottom of spool 3, valve body 1 and the valve.The middle part of spool 3 have can with cold water hole, annular intake chamber and hole that hot water hole and water space 9 are communicated with respectively.The lower end of spool 3 and valve body 1 screw-thread fit, rotary spool just can change annular intake chamber and hole and the cold water hole on the spool, the hot water hole, connected relation between the water space, can make valve be in the open and close state respectively, and emit the warm water of cold water, hot water and different hot and cold water ratios respectively, thereby can reach the purpose that adjusts coolant-temperature gage.Valve gap 5 and handle are housed on the upper end portion of spool 3.Rotatable handle 4 can make valve core rotation, reaches to open valve simultaneously, regulates the purpose of water temperature.

In order to prevent that valve outlet from leaking, Sealing 10 is arranged at the mating part of spool lower end and valve body.

For the upper end that prevents valve leaks, Sealing 11 is arranged in the joint of valve body 1 and valve gap 5.

The hot and cold water heat control valve of the utility model design is simple and reasonable, only needs handle of operation just can reach the purpose of opening valve and regulating water temperature, can not change the water yield in the temperature adjustment process.Owing to adopt and to become spool by rotatablely moving of screw-thread fit and move up and down and control the inflow at the cold and hot mouth of a river, therefore in use, the position of the cold and hot mouth of a river and spool relative opening can not change easily, and the constant water-exit temperature of the hot water temperature who only wants in is very stable.

Further specify mode of execution of the present utility model with following indefiniteness embodiment.

Fig. 1 is the longitudinal sectional view of heat control valve.Heat control valve is a cylindrical structural.It is by valve body 1, at the bottom of the valve 2, and spool 3, round shaft 4, valve gap 5 and some Sealings are formed.At the bottom of valve body, the valve, the structure of spool, round shaft sees Fig. 3,4,5,6.Hot water hole and cold water hole equal diameters, its axis are distributed in the opposite side of valve body at same vertical plane, the hot water hole on the top of valve body, cold water hole is under the hot water hole.The warm water exit orifice valve body below, and with the axis normal of heat, cold water hole.There is the rubber seal Sealing lower end of spool, and sealing is used during as valve closing.The lower end of spool and valve body screw-thread fit.There are annular intake chamber and hole in the middle part of valve body, valve gap 5 is housed on the upper bar of spool, valve core rod exposes outside valve gap, and exposed portions serve is equipped with round handle, and for preventing the mutual seepage of hot and cold water, there is rubber gasket the centre of spool and valve body.Adopt between valve gap and valve body and be threaded.

During use, first slewing circle handle 4, handle drive the spool rotation, and cold water is flowed out by mixed water exports 8 after spool 3 flows into water space 9 by cold water hole.Be rotated further round shaft 4, make spool 3 continue to rise, the annular intake chamber on spool is communicated with hot water hole 7, at this moment cold water, hot water flow into 9 backs, water space simultaneously by mixed water exports 8 outflows, along with the rising of spool, the ratio of hot water progressively increases, and the water temperature of water outlet also increases thereupon.Round shaft 4 rotates round about, then the ratio with the decline hot water of spool 4 gradually reduces, the water temperature of water outlet also decreases, and can only need operate a handle by user's needs and just can open valve easily and regulate water temperature thereby reach.Because the equal diameters of hot water hole and cold water hole, so the water-outlet quantity of mixing water is not subjected to the influence of temperature adjustment.
