Description

The memory alloy temperature control apparatus

Technical field

The utility model relates to a kind of temperature control apparatus, especially relevant memory alloy temperature control apparatus.

Background technique

Existing memory alloy temperature control apparatus, generally form by component such as valve body, spool, bias spring, memory alloy spring, valve gaps, for example, China Patent No. is 03242816.2, the patent documentation of a kind of fluid temperature control valve by name discloses similar structure, there is following shortcoming in it: the spool front end is equipped with a piston, complex structure, the action transmission link is many, and it is not really accurate to move; Spool and spring stop are connected as a single entity, and spring stop cooperates the formation kinematic pair with the valve gap endoporus, and the endoporus processing length is long, and required precision is higher; Bias spring has one section not have the spool guiding, and stability of motions is bad.

Summary of the invention

It is a kind of simple in structure, easy to process that the purpose of this utility model is to provide, the memory alloy temperature control apparatus of good stability.

In order to achieve the above object, the technical solution of the utility model is: a kind of memory alloy temperature control apparatus, comprise valve body, bias spring, memory alloy spring, valve core rod and valve gap, valve body is provided with intermediate clapboard, intermediate clapboard is provided with slide opening, valve core rod is slidably supported in the slide opening, bias spring and memory alloy spring lay respectively at the left and right sides of intermediate clapboard and are sleeved on the valve core rod, the bias spring two ends respectively with valve core rod on left spring retaining and intermediate clapboard on the left of offset, the memory alloy spring two ends respectively with intermediate clapboard right side and valve core rod on right spring catch offset.

After adopting said structure, because the cancellation piston, so structure is simpler, and the action transmission link has lacked, and it is more accurate to move, and makes also simpler; Because valve core rod and intermediate clapboard are not one, the slide opening of valve core rod and intermediate clapboard forms kinematic pair again, and the slide opening processing length is short, so required precision is also lower, easily processing; Also because bias spring and memory alloy spring are enclosed within on the valve core rod so movement of springs good stability fully.The utility model not only can be used for the fluid temperature control of gear case oil adjustable valve etc., also can be used for the gas temperature control of fire-fighting fire alarm equipments etc.

Embodiment

The embodiment who provides below in conjunction with accompanying drawing does explanation in further detail to the utility model.

As Fig. 1,2, shown in 3, memory alloy temperature control apparatus of the present utility model, comprise valve body 1, bias spring 6, memory alloy spring 5, valve core rod 4 and valve gap 2, valve body 1 is provided with intermediate clapboard 1-1, intermediate clapboard 1-1 is provided with slide opening 1-1-1, valve core rod 4 is slidably supported among the slide opening 1-1-1 of intermediate clapboard 1-1, bias spring 6 and memory alloy spring 5 lay respectively at the left and right sides of intermediate clapboard 1-1 and are sleeved on the valve core rod 4, bias spring 6 two ends respectively with valve core rod 4 on left spring retaining 7 and intermediate clapboard 1-1 left side offset, memory alloy spring 5 two ends respectively with intermediate clapboard 1-1 right side and valve core rod 4 on right spring catch 4-1 offset.

Shown in Fig. 1,3, in order to give valve core rod 4 guiding better, the guide hole 2-1 of valve gap 2 and valve core rod 4 periphery cunnings are joined.

As shown in Figure 3, in order to give moving axially of valve core rod 4 spacing, when valve core rod 4 moved, the right flank of right spring catch 4-1 can offset with valve gap 2 left surfaces.

As shown in Figure 1, 2, 3, for realize valve core rod 4 certainly in and self adaption, reduce to install and requirement on machining accuracy, the working end 4-2 head of valve core rod 4 is tapered.

Shown in Fig. 2,3, for the temperature of perception liquid or gas better, valve body 1 is the open-type structure.

Shown in Fig. 1,2,3,4, for the ease of installing, valve body 1 bottom has adpting flange 1-2, has some attachment hole 1-2-1 on the adpting flange 1-2.

As shown in Figure 5, valve gap 2 ends also can have connecting base 2-2, have some attachment hole 2-2-1 on the connecting base 2-2.

As Fig. 1,2,3,4, shown in 5, when the utility model is used for high-speed gear box oil sump or other liquid-container, can adpting flange 1-2 be fixed on the base plate 9 of oil sump or liquid-container by screw 8, also can be fixed on the baffle plate 10 of oil sump or liquid-container by the connecting base 2-2-1 of screw 8 with valve gap 2, with the path 10-1 on the baffle plate 10 in valve core rod 4 right-hand member heads aligning oil sump or the liquid-container, when temperature is low in oil sump or liquid-container, memory alloy spring 5 is failure to actuate, path 10-1 is on state, makes the oil or the fluid connection of baffle plate 10 both sides; After temperature in oil sump or the liquid-container surpasses the operating temperature of memory alloy spring 5, memory alloy spring 5 begins action, and valve core rod 4 moves right, and its right-hand member head enters the path 10-1 on the baffle plate 10, stop up path 10-1, the oil or the liquid of baffle plate 10 both sides are not communicated with.
