Abstract

The utility model relates to a temperature controlling device, comprising a base, an adjusting shaft, a bellow, a diaphragm, a bellow seat board and a temperature sensing head, wherein, the base is connected with the adjusting shaft screw thread, and the adjusting shaft and the bellow are connected with a small shaft through a shaft hole; the lower part of the bellow is riveted with the diaphragm which is provided with a few tracks of concentric circle projections, and the diaphragm is contacted with a through hole screw nail on the bellow seat board. The utility model has relatively ideal temperature controlling effect because of uniform thermal expansion and concentrated deformation.

Description

A kind of temperature controller

The utility model belongs to the temp control switch device.

The temperature controller of Shi Yonging in the market, its bellows and regulating shaft simply are abutted against, easily slide, be welding between bellows and diaphragm, solder joint metallographic structure on every side changed cause the thermal expansion inequality, in addition, diaphragm and bellows seat board connect together, because contact area is big, deformation is very little, so temperature control effect is undesirable.

The purpose of this utility model provide a kind of thermal expansion evenly, the temperature control equipment in the deformed set.

The technical solution of the utility model is as follows:

Temperature controller comprises pedestal, regulating shaft, bellows, diaphragm, bellows seat board and temperature-sensitive head, pedestal and regulating shaft thread connection, regulating shaft connects with the little axle on bellows top with the axis hole with by the regulating shaft bottom of bellows, be riveted joint between bellows and the diaphragm, diaphragm contacts with perforation screw on the bellows seat board.

Diaphragm is the sheet metal that several roads concentric circles projection is arranged.

Because the utility model compact conformation, thermal expansion is even, and stressed concentrating is so temperature control effect improves greatly.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the diaphragm front elevation;

Fig. 3 contacts synoptic diagram for the switch motion parts with contact head.

Be described further below in conjunction with accompanying drawing:

Thread connection one regulating shaft 3 on pedestal 1, an axis hole 6 is opened in regulating shaft 3 lower ends, and the little axle 5 on the bellows 2 is just put into axis hole 6, and bellows 2 is connected with temperature-sensitive head 13 by lead 12, and lead 12 is that metal is carefully alert, communicates with bellows 2 inside, wherein is full of fluorine Lyons liquid.Bellows 2 lower end riveting ends one diaphragm 4, diaphragm 4 is for there being the sheet metal of several roads concentric circles projection, a bellows seat board 7 is fixed with screw 9 in the diaphragm below on pedestal, fix a perforation screw 8 over against diaphragm 4 circle centre positions in the middle, the other end of bellows seat board 7 is fixed a contact head 10, contacts with switch motion parts 11.

When temperature-sensitive head 13 intensification of being heated, conduct heat by lead 12 and to give fluorine Lyons liquid in the bellows 2, fluorine Lyons expanded by heating, bellows 2 is expanded, extruding diaphragm 4 promotes perforation screw 8 and moves down, and contact head 10 pull switch action components 11 and sheet metal 14 are disconnected, and reaches the temperature control purpose.

Claims

1, a kind of temperature control equipment, comprise pedestal (1), regulating shaft (3), bellows (2), diaphragm (4), bellows seat board (7) and temperature-sensitive head (13), it is characterized in that: pedestal (1) and regulating shaft (3) thread connection, axis hole (6) by the regulating shaft bottom between regulating shaft (3) and the bellows (2) connects with the little axle (5) on bellows top, be riveted joint between bellows (2) and the diaphragm (4), diaphragm contacts with perforation screw (8) on the bellows seat board (7).

2,, it is characterized in that described diaphragm (4) is a sheet metal that several roads concentric circles projection is arranged according to the described attemperating unit of claim 1.
