CN2130981Y - Five-position single-spool three-way hole valve - Google Patents

Abstract

The utility model discloses a five-position single-valve core three-way hole valve. The five-position single-valve core three-way hole valve not only can regulate the mixture of two fluids, but also can regulate any one fluid of the two fluids. Usually, two one-way valves are adopted to respectively control the two fluids, which brings much trouble, and the two one-way valves are especially inconvenient in the process of installation and operation. The five-position single-valve core three-way hole valve is only provided with one valve core, but the five-position single-valve core three-way hole valve can control the two fluid, and the five-position single-valve core three-way hole valve has no special requirement to the valve core. Only two sides of the middle body of the valve core in a cone cylinder shape are provided with two side groove holes, therefore, the structure of the five-position single-valve core three-way hole valve is very simple. Three through holes are arranged on a valve seat. The five-position single-valve core three-way hole valve is characterized in that two water inlet holes are respectively less than a third through hole (a mixed flow pipe). The five-position single-valve core three-way hole valve has the advantage that one valve has a plurality of purposes. The five-position single-valve core three-way hole valve can be widely used for a family, a bathroom, a restaurant, a guesthouse, etc.

Description

Five-position single-spool three-way hole valve

The utility model relates to a kind of adjusting liquid, gas, particularly regulates the device of hot water and cold water mix, the effect that also has one-way valve simultaneously.

At needs hot water and cold water, the place that needs warm water again must relate to the problem of controlling two kinds of fluids, and two single-pass formula valves generally are installed, when controlling the different water flow of two valves, will operate two valves simultaneously, so just bring a lot of troubles, especially in installation process, these two valves connect many, materials are many, take up space, and install with operation all inconvenient.

The utility model purpose be that a kind of simple structure will be provided, five novel single spool threeway ports valves, it not only can make general one-way valve usefulness, can also close the mixing of using two kinds of water temperature arbitrary proportions effectively and regulate.

The utility model purpose is achieved in that

A spool that is sealed in the conical cylinder shape that to rotate in the threeway valve seat core hole, when valve body becomes closed condition, two side end faces being formed by two side channel holes of body in the spool, closely paste and be covered with two valve seat water inlet through holes, thereby two intake pipe outlets are blocked simultaneously, rotational valve core, make an intake pipe sealing, another intake pipe is linked up by the side channel hole and the third through-hole outlet pipe (also claiming mixed flow tube) of spool, rotational valve core equally round about, thereby another intake pipe and mixed flow are linked up reached the purpose of selecting two kinds of fluids, in addition, just can be after having selected a fluid when needing a kind of fluid big or small, suitable rotational valve core just can obtain needed flow.

If when needing the fluid-mixing of two intake pipes simultaneously, rotational valve core makes its side end face facing to mixed flow tube, thereby two " the other holes " of the fluid that makes two intake pipes by forming by the side end face and the mixed flow tube of spool, suitable rotational valve core, can change the mixed flow body that two other hole sizes also just can obtain arbitrary proportion, its mixing temperature just can have been controlled arbitrarily for hot water and cold water.Spool has small one and large one two end faces.When the big side end face of spool faced toward mixed flow tube, the amount of mixed flow was just little, and vice versa.

The utility model is because have only a spool, and spool there is not special requirement yet, only need in the spool of conical cylinder shape, open two side channel holes in the body both sides, so structure is simple especially, valve seat also is to have increased the 3rd through hole on the basis of former one-way valve, the threeway central point of hole of valve seat is all in same plane, the center line in process valve seat core hole is perpendicular to this face, this valve has the characteristics of multi-purpose valve, of many uses, it not only can be used for general family, and can be widely used for public bathhouse, dining room, hotel, factory etc.

The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.Fig. 1 is five the single spool threeway ports valves proposing according to model utility and the sectional drawing of spool, and Fig. 2 is five valve element position figure of this valve.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2 according to the concrete device that the utility model proposes.

This device comprises a valve seat (1), two two through hole (9) and (10) that are on the straight line are arranged in the valve seat, third through-hole (mixed flow tube) (12), valve seat core hole (11), the spool (2) that can in valve seat core hole, rotate, comprise spool upper body (a), middle body (b), lower body (c), two side channel holes (3) of spool, (4), space (15) between bottom, valve seat core hole (11) and spool lower body (c), lubricating pad (6) is arranged above the spool in addition, cushion (7), sealing cover (8) spool handle and connecting rod (5), two side end faces of body in the spool (b): big side end face (14), little side end face (13), third through-hole (12) is greater than the big side end face of spool (14), the big side end face of spool (14) is greater than the little side end face of spool (13), and the little side end face of spool (13) is during respectively greater than valve seat two through hole (9) and (10).

Fig. 2 (A) whole valve body becomes closed condition.

(B) two fluid streams flow to mixed flow tube via through hole (9) and (10) by two " the little other holes " that big side end face (14) and mixed fluid hose (12) form respectively.

(C) through hole (9) is in closed condition, and another through hole (10) is linked up by body (b) side channel hole in the spool and mixed flow tube (12).

(D) through hole (10) is in closed condition, and another through hole (9) is linked up by body (b) side opening in the spool and mixed flow tube (12).

(E) two fluid streams flow through two " big other holes " being formed by little side end face (13) and mixed flow tube (12) up to mixed flow tube by through hole (9), (10) respectively.

The last figure in Fig. 1 right side is " figure A ", and figure below is " figure B ".

Figure A is the mansion view of threeway ports valve core.

Figure B is the side view of threeway ports valve core.

In figure A, figure B, spool handle and connecting rod (5), body (b), little side end face (13) in the spool of big side end face (14), spool side channel hole (3), (4).
