Abstract

The utility model relates to a water temperature adjusting and controlling valve for the shower which can be used for the bearing hot water shower, and can also be used for the non-pressure hot-water shower. The utility model is mainly composed of a valve core, a valve sleeve, a valve body, and a temperature adjusting turn knob. Three channels are arranged on the valve core, the valve sleeve, and the valve body. The fluid flow of the two of the three channels can be changed by rotating the valve core, and the purpose of adjusting the temperature is obtained. The utility model can be widely used for the places of the bathhouse, the household, the barber shop, the beauty treatment shop, etc.

Description

Shower water temperature adjusting control valve

A kind ofly both be applicable to the bearing hot water shower, be applicable to the shower water temperature adjusting control valve of non-pressure hot water shower again.

At present, by the shower publilc baths of boiler supplying bearing hot water or the shower in the hotel room, the regulation and control of water temperature generally all by two independently stop valve finish.In this case, water temperature is difficult to be transferred to desirable degree.No. 92237842.8, Chinese patent disclosed " water temperature modulating valve ", though realized with a valve temperature adjustment, because of the complex structure of valve internal, not only make difficulty, the reliability of its action also can be affected because of the structure of complexity in concrete the use.

The purpose of this utility model is to provide valve of a kind of usefulness can realize temperature adjustment, and both has been applicable to the bearing hot water shower, is applicable to the shower water temperature adjusting control valve of the usefulness of the non-pressure hot water shower that general water heater, water heater are supplied again.

The purpose of this utility model realizes by following proposal, on the different direction of spool, have three ducts of interpenetrating, on the respective direction of valve pocket and valve body, also have corresponding duct, under the situation of breakdown shower water temperature adjusting control valve, rotational valve core, can change wherein the fluid flow in two passages, thereby reach the purpose of temperature adjustment.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is an elevational cross-sectional view of the present utility model.

Fig. 2 is a vertical view cutaway drawing of the present utility model.

Among the figure, [1]---thermoregulation knob, [2]---pinion, [3]---knob base, [4]---valve body, [5]---valve pocket, [6]---spool, [7]---gear wheel, [8]---The box shell, [9]---spring, [10]---single track water pipe, [11]---road water pipe. Have three holes of interpenetrating on spool [6], valve pocket [5], the valve body [4] The road. Wherein, in three ducts on valve pocket [5], corresponding on the spool [6] The aperture of macropore is less than the upper aperture than macropore of spool [6]. Spool [6] upper with The hole that single track water pipe [10] connects is bigger, and its big or small degree will guarantee that spool [6] exists Rotate in the temperature adjustment process, the unlikely change in effective perforation cross section of this passage, this is logical Effective perforation cross section in road is determined by the upper corresponding hole of valve pocket [5]. Spool [6] Upward and aperture littler with two holes of two pass water pipe [11] perforation equates these two The aperture in hole upward also equates in the aperture in corresponding duct with valve pocket [5]. This two couple The hole is that dislocation cooperates, in the situation that all standard-sized sheet is logical of two pairs of holes, and the having of each passage The effect cross section all only has half of each hole actual cross-section. In rotational valve core [6] temperature adjustment The time, the effective cross-section of one of them passage increases, and the effective cross-section of another passage subtracts Few, but total effective cross-section of two passages is constant. After shower finishes, spool [6] Turn to the effective area of two passages that connect with two pass water pipe [11] is all wanted When equalling zero, whole shower water temperature controlling valve just is taken at closed condition. Spool [6] Upper realize with valve pocket [5] driving fit by spring [9], rotational valve core [6], valve pocket [5] can not be shifted. On the axle of spool [6] top gear wheel [7] is housed, temperature adjustment is revolved Pinion [2] is housed under the button [1], rotates thermoregulation knob [1], pinion [2] along with Rotate, under the drive of pinion [2], gear wheel [7] rotates, and drives simultaneously valve Core [6] rotates. Certainly, if with a soft pure replacement pinion [2] and gear wheel [7], when rotating, thermoregulation knob [1] rotated by soft pure band movable valve plug [6] or clear-cut Thermoregulation knob [1] is contained on the axle of spool [6], when thermoregulation knob [1] rotates Directly band movable valve plug [6] rotates and all is fine. For easy to operate, can The appropriate location of the below of thermoregulation knob [1], mark " pass ", " cold ", Printed words such as " heat ", when thermoregulation knob [1] turns to the closed position of indication, With the duct Close All that two pass water pipe [11] connects, the shower water temperature controlling valve namely Be in closed condition, at this moment, cold water or hot water all can not pass through. Work as temperature adjustment Knob [1] indication, when rotating in the hot and cold thermoregulation range, the two pass water pipe [11] fluid flow in two water pipes can be changed, wherein, and the stream in one Quantitative change is big, and the flow in another root diminishes, but the total flow in two water pipes is not Become.

Be embodiment of the present utility model below

Embodiment one: in the bathroom of bearing hot water, one in the two pass water pipe [11] is communicated with tap water, another root is communicated with hot-water line, shower nozzle is communicated with single track water pipe [10], when hot water service needs shower, open shower water temperature adjusting control valve, rotate thermoregulation knob [1], can obtain desirable shower warm water.

Embodiment two: in the shower publilc baths of barber shop or non-pressure hot water, or in the family toilet, single track water pipe [10] is communicated with running water pipe, after one in the two pass water pipe [11] hot-water line with non-pressure hot water container hot-water supply is communicated with, lead to shower nozzle or hot water outlet jointly, two pass water pipe [11] another root that neutralizes is communicated with hot water tank.After opening shower water temperature adjusting control valve, rotate thermoregulation knob [1], can obtain the warm water of desirable shower or hair washing usefulness, simultaneously, non-pressure hot water also can obtain the cold water supply in holding.

With existing heat control valve relatively, the utlity model has simple in structure, operation Reliably, open and close the characteristics such as flexible, can be widely used in publilc baths, family, haircut U.S. The places such as appearance shop.
