Embodiment
Embodiment one:
Like Fig. 1, the utility model embodiment one sectional view; This valve is unidirectional straighttube-type, has the body of opening at a two 10; In the body 10, the temperature-sensitive assembly comprises memory alloy body 112 and terminal push rod 113, joint 111 thereof; In the downstream of temperature-sensitive assembly the pilot valve assembly is arranged, comprise guide's spool 124, fixed cover 121 and plug 122.In the direction of arrows, the hot water from joint 111 is come in is immersed in memory alloy body 112 wherein, if temperature surpasses the recovery temperature of memory alloy body 112, then memory alloy body 112 can the downstream direction stretch, and promotes push rod 112; Push rod 112 slides in fixed cover 121 downstream, and the pilot port 124a that the fixing plug 122 in its top stops up in the pilot valve assemblies makes the water route in guide's spool 124 shutoff downstream.This embodiment's volume is less, can be docked with between the multiple pipe fitting.
Embodiment two:
Like Fig. 2, embodiment's two three-dimensional explosive views of the utility model have been showed each critical piece; Handle 100 and shower head 200 have constituted the major component of whole crust of the device, the two hollow, and inside has connection and complete water route.
The temperature-sensitive assembly 110 of present embodiment, pilot valve assembly 120 and through swtich 130 three parts concentrate on handle 100 inside basically, from handle 100 ends to shower head 200 are respectively:
Temperature-sensitive assembly 110 has comprised joint 111, memory alloy body 112 and push rod 113; Its middle joint 111 is fixed in handle 100 ends, has also constituted the part of shell, and an end of memory alloy body 112 is fixed.The other end of memory alloy body 113 can be axially movable, and fixing push rod 113.
Through swtich 130 has comprised button 131, adjustable pipe 132 and second stage clip 133; Wherein be connected with second stage clip 133 between adjustable pipe 132 and the shower head 200; Button is then inserted fixing down from the hole in handle 100 outsides, cooperate with adjustable pipe 132; Can find out that on scheming button 131 is through the inclined-plane of a guiding, self the control adjustable pipe 132 that moves up and down is formed axial motions, thus make adjustable pipe 132 with respect to guide's spool 124 axially near or away from.So-called through swtich mean the corresponding respectively whole device of its ON/OFF whether be in straight-through, expedite state; Lead directly to and promptly removed all high temperature protection functions, otherwise all protective functions are still effective.
In this example, memory alloy body 112 selection reminiscence temperature are 45 ℃ material, the profile of spring-like, and make it be lower than the state that keeps axial compression under the situation of this temperature.After getting into handles 100 from the current of outside from joint 111; Flow through memory alloy body 112; Along space between setting sleeve 121 and handle 100 inwalls and the space between guide's spool 124 and handle 100 inwalls, flow in the space at pad 125 places again.
Fig. 3 is the side view that band embodiment illustrated in fig. 2 is analysed and observe, and has showed normal operating condition, and the signal in water route, and dotted arrow is a water (flow) direction among the figure.Normal current get into from joint 111, immediately through setting sleeve 121 and the gap of guide's spool 124 integral body with handle 100 inwalls, arrive the cavity at pad 125 places.In this position, the leather cup 124a of guide's spool 124 does not touch with the end of adjustable pipe 132 mutually, has the gap, thereby current can flow into adjustable pipe 132 in the position of pad 125, thereby to shower head 200 outflows, forms normal operating condition.Under this state, because water temperature obviously is not higher than 45 ℃, thereby memory alloy body 112 is in compressive state; Its axial length is less; The pressure that cooperates first stage clip 124, plug 122 does not touch with pilot port 124b in guide's spool 124 mutually, but near the upper reaches inwall of setting sleeve 121.
Fig. 4 is the sectional view of guard mode embodiment illustrated in fig. 2.The realization state of promptly having showed the high temperature protection function.Because memory alloy body 112 is immersed in the current all the time; Real-time monitor water temperature; When surpassing 45 ℃ of preset temperatures, memory alloy body 112 begins towards downstream that direction stretches, and its stress is obviously greater than the stress of first stage clip 123; Through push rod 113 drive plugs 122 toward pilot port 124b near, and final the obstruction.Therefore, its internal pressure of leather cup 124a of guide's spool is greater than external pressure, so leather cup 124a expands; The end of conflict adjustable pipe 132; Make current reside at the outer fix of leather cup 124a and can't flow to adjustable pipe 132, thereby turn-offed the water outlet of adjustable pipe 132, the purpose of the protection that reaches a high temperature.Through design to memory alloy body 112 parameters, and the coupling of first stage clip, 123 parameters, can obtain the effectively memory alloy body 112 of stretching, extension taking place, to satisfy different water temperature protection demands in different temperature points.
Fig. 5 is the sectional view of pass-through state embodiment illustrated in fig. 2.Under this state, button 131 has been pressed, thereby adjustable pipe 132 is slided downstream; Cause the slit between leather cup 124a and adjustable pipe 132 ends to increase; No matter which kind of state memory alloy body 112 is in simultaneously, and whether plug 122 stops up pilot port 124b, and current all can get into adjustable pipe 132.This state has been removed the protective function of whole device through an action of pushing maintenance to button 131, and from another angle, only otherwise push on one's own initiative and hold button 131, device can be operated in automatic guard mode.
Fig. 6 is a pilot valve components detailed cross sectional view embodiment illustrated in fig. 2.In fact the upstream extremity at setting sleeve 121 has ccontaining push rod 113 most push rod chamber 121a; And the push rod stage casing has a piston 113a, and memory alloy body 112 is socketed on the push rod 112, axially contacts this piston 113a.The hydraulic pressure that piston 113a both sides receive in the use does not wait, and produces the pressure towards the upper reaches, and push rod 113 is driven plug 112 has damping function when direction stretches towards downstream.
Guide's spool axially is being divided into two cavitys: first guide cavity 124c and back pressure cavity 124d, and this two cavity is communicated with through a honeycomb duct 124e; Downstream one side of back pressure cavity 124d promptly is leather cup 124a, and this leather cup 124a has a needle-valve 124f and has been communicated with back pressure cavity 124d; Also have a pressure relief opening 124h in leather cup 124a central authorities, this pressure relief opening 124h has been communicated with the downstream side of pilot port 124b and leather cup 124a.
In the use,, drive plug 122 through push rod 113 and stopped up pilot port 124b when memory alloy body 112 stretches; Back pressure cavity 124c is only by the unidirectional input current of needle-valve 124f; Because the inboard of leather cup 124a is that downstream side hydraulic pressure useful area is big than the outside, so outwards expansion of this state down cup 124a, the adjustable pipe 132 that does not move touched; Block the output current of adjustable pipe 132, reach the state of protection.Water temperature does not surpass when perhaps the recovery and protection temperature is following; Plug 122 motion upstream under the hydraulic pressure that first stage clip 123 and piston 113a receive; Discharge pilot port 124b; Because pilot port 124b has been communicated with pressure relief opening 124h, so the hydraulic pressure deficiency is so that leather cup 124a expands in the back pressure cavity 124d, this is normal dress attitude.The omnidistance auxiliary resilience shape of having kept leather cup 124a of Returnning spring 124g.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented according to this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
