Abstract
The utility model relates to a mechanical valve with temp. control head, which is composed of a temperature-sensitive plug, a connecting pipe, a supporting seat and an acting head, wherein, the temperature-sensitive plug is plugged on end of the connecting pipe and is fixed with a pull rod; the connecting pipe is connected with the supporting seat, and the pull rod is penetrated through the connecting pipe to connect with the acting head; the convex head of the acting head is arranged on the open end of the supporting seat, and the back part is provided with a compaction spring; when the temperature-sensitive plug is melted, the acting head is pushed by the spring to move forward, and other devices are pushed or blocked.
Description
The utility model relates to a kind of mechanical-type temperature control head.
Prior art mainly contains three kinds than the mechanical-type temperature control components and parts of extensive use: bimetal strip thermostat.Compression-type temperature controller and fusible plug temperature controlling device.These temperature control components and parts are because design and the defective of itself.Exist output torque little.The short shortcoming of an action stroke is not so also there is to produce the mechanical-type refractory protection that cuts off fuel gas pipeline when being applied to the fire generation automatically so far.
It is big that the purpose of this utility model provides a kind of output torque, and an action stroke is controlled, simple in structure, the mechanical-type temperature control head of reliable in action.
The utility model temperature control head is by temperature-sensitive plug, connecting tube, and supporting base and action head are formed, and it is characterized in that: the temperature-sensitive plug is fusible alloy fusible plug, and its plug is at an end of connecting tube, and the other end of connecting tube links to each other with supporting base.Also solidify a pull bar in the temperature-sensitive plug, pull bar passes the connecting tube center and links to each other with the action head, and the action head is the metal round rod with plush copper.It places the supporting base opening end, and plush copper is outside, and there is a compacted spring plush copper back.When running into the temperature that is higher than its fusing point, the temperature-sensitive plug melts.Fused plug fastening pull bar just be released, the action head of the pull bar the other end outwards moves under the promotion of spring like this.Promote or block other devices to reach purpose of design.
Supporting base in the above-mentioned temperature control head is made up of the metal pipe element of two different internal diameters, and it is outer through having hexagonal nuts and positive thread; Pull bar forms and can move in connecting tube by Steel Wire Strand is stranded.
The utility model temperature control head, simple in structure, move reliable and stable, the characteristics that cost is low.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of temperature control head.
In structural representation shown in Figure 1, temperature-sensitive plug 6 and connecting tube 4, the pull bar 5 of temperature control head are connected, the other end of connecting tube links to each other with supporting base 3, pull bar 5 passes the center of connecting tube 4, link to each other with action 1, action is the metal round rod with plush copper, and there is a spring that compresses 2 the plush copper back, supporting base is made up of the metal pipe element of two different inner diameters, and its external diameter has hexagonal nuts and outer rib-loop.Be used for it is fixed on other devices, be convenient for changing.Pull bar forms by Steel Wire Strand is stranded, being connected pipe can be crooked together, and do not influence pull bar moving in connecting tube, can make the connecting tube of this temperature control head crooked like this because of need, increase the function of its far-end control, melt in case the temperature-sensitive plug runs into when being higher than the temperature of setting fusing point, fastening position bar is released, the action head will be promoted by spring, and the moment of action head output is by the elastic force decision of spring.Effective displacement distance of action head, by the length of length of spring compressed, the length control of supporting base action head.
