A kind of cold-hot integrated formula ceramic valve
Technical field
The present invention relates to ceramic valve technical field, be specifically related to a kind of cold-hot integrated formula ceramic valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.At valve internal, normally by spool, complete closing and opening valve with the relative action of valve body, very frequent of the unlatching of valve in the process of using, so the wear resistance of spool and valve body material and aging have determined the life-span of valve greatly.Therefore in a lot of valves, spool and valve body are brought into use ceramic material, but the difficulty of processing of pottery is very big, simultaneously because pottery is to fire to form, the profile ratio of regular shape even thickness is easier to produce, and the profile of most of spools and valve body irregular, and the difficulty of processing of complicated shape pottery is very big, this makes ceramic valve be difficult to large-scale popularization.
Manyly be with valvular product needed to there are cold and hot two liquid lines, these product needed can be emitted respectively cold water and hot water, water pipe to drinking machine, while having a bath etc., if at this moment use two different valves can make liquid line structure comparatively complicated, install also and comparatively bother, if use a valve, because spool is usually changed between cold and hot, easily damage life of valve shorter.
Summary of the invention
For above problem, the invention provides the letter of a kind of spool valve body structure and answer, can in an outlet, realize the cold-hot integrated formula ceramic valve of hot and cold water conversion.
The technical solution adopted for the present invention to solve the technical problems is: this cold-hot integrated formula ceramic valve comprises spool, the valve body that is assemblied in enclosure interior use ceramic material; Described spool, valve body are straight tube shape, described spool can endwisely slip through described valve body, described spool top seal, in the annular wall of described valve body, be processed with along the valve body hole of two parallel kidney-shapeds of axial direction, the neutral position of described spool annular wall is processed with valve body hole size and matches along a parallel spool bore of axial direction; On described spool, be connected with the catch bar that axially vertically stretches out described valve body; Two valve body hole outsides of described valve body are respectively fitted with the liquid inlet joint being communicated with valve inner.
As preferably, the top of described valve body seals by the chock plug of ladder truncated conical shape, and spool top is inserted in one end sealing of described chock plug small column, by pin, fixes, and the top of described chock plug is fixed by spring and housing, and described spool is relative with housing fixing.
As preferably, the bottom of described valve body is equipped with water output connector, and described spool bottom is stretched out valve body and partly goed deep in described water output connector.
Beneficial effect of the present invention is: spool and the valve body structure of this cold-hot integrated formula ceramic valve are simple, is applicable to using ceramic material.Being assemblied in liquid inlet joint on valve body can be used for being connected with different temperatures or liquid of different nature respectively, while closing, the spool bore of spool is between two valve body holes of described valve body, during use, only need to control described spool by described catch bar just moves up and down and spool bore can be connected with valve body hole respectively, thereby pass into different liquid in spool, or the water of different temperatures.This valve concentrates on two different water inlet position on a valve body, by sliding up and down of spool, water outlet is communicated with different liquids circuit, easy to use.The spool, the valve body that use ceramic material, rub resistance is difficult for aging high life.

Embodiment
Below in conjunction with embodiment, the present invention is further described:
As shown in embodiment in Fig. 1, this cold-hot integrated formula ceramic valve, it comprises spool 2, the valve body 3 that is assemblied in the inner use ceramic material of housing 1; Described spool 2, valve body 3 are straight tube shape, wherein the external diameter of spool 2 is identical with the internal diameter diameter of valve body 3, described spool 2 can endwisely slip through described valve body 3, described spool 2 top seals, as depicted in figs. 1 and 2, in the annular wall of described valve body 3, be processed with along the valve body hole 31 of two parallel kidney-shapeds of axial direction; As shown in figures 1 and 3, the neutral position of described spool 2 annular wall is processed with valve body hole 31 sizes and matches along a parallel spool bore 21 of axial direction.On described spool 2, be connected with the catch bar 22 that axially vertically stretches out described valve body; Two valve body hole 31 outsides of described valve body 3 are respectively fitted with the liquid inlet joint 32 being communicated with valve inner.On this valve, other each element has described housing 1 to be linked and packed together.
The spool 2 of cold-hot integrated formula ceramic valve is simple in structure with valve body 3, and the two is toroidal, has identical wall thickness, is applicable to using ceramic material, and easily processing, can reduce costs greatly.The liquid inlet joint 32 being assemblied on valve body 31 can be used for being connected with different temperatures or liquid of different nature respectively.As shown in Figure 1, while closing, the spool bore 21 of spool 2 is between two valve body holes 31 of described valve body 3, during use, only need to control described spool 21 by described catch bar 22 just moves up and down and spool bore 21 can be connected with valve body hole 31 respectively, thereby pass into different liquid in spool 2, or the water of different temperatures.This valve concentrates on two different water inlet position on a valve body 3, by sliding up and down of spool 2, water outlet is communicated with different liquids circuit, easy to use.The spool 2, the valve body 3 that use ceramic material, rub resistance is difficult for aging high life.
As shown in Figure 1, the top of described valve body 3 is by chock plug 4 sealings of ladder truncated conical shape, and spool 2 tops are inserted in one end sealing of described chock plug 4 small columns, fixing by pin 5, the top of described chock plug 4 is fixing with housing 1 by spring 6, and described spool 2 is relative with housing 1 fixing.Described spring 6 both can also can bear pressure by bearing tension, spool bore 21 on spool 2 described in this spring 6 is in the raw time is just in time in the middle of described two valve body holes 31, when no matter user promotes described spool 2 by described push rod 22 to which direction, it all can be subject to middle restoring force, like this when people unclamp described push rod 22, this valve all can be returned to closed condition, more convenient during use.
As shown in Figure 1, the bottom of described valve body 3 is equipped with water output connector 7, and described housing 1 is stretched out in the bottom of described water output connector 7, in described water output connector 7, is processed with water cavity road.Described water output connector 7 can be avoided spool that opening type need to be flexible up and down directly and external contact, and described water output connector 7 positions immobilize, and are more convenient to people at bottom water receiving.
