Abstract
The invention discloses a tornado valve operating mechanism, comprising a main spiral arm, a plurality of auxiliary spiral arms, a transmission rod and an elastic piece, wherein the main spiral arm is connected with one end of the transmission rod; the elastic piece is connected with the other end of the transmission rod; a heavy punch is arranged on the main spiral arm; the auxiliary spiral arms are connected onto the transmission rod between the main spiral arm and the elastic piece; the main spiral arm and the auxiliary spiral arms are respectively sheathed on rotating shafts. According to the tornado valve operating mechanism, as an original executing mechanism and an original complexity control system which are high in manufacturing cost are replaced by a spring and heavy punch combined mechanism, not only is the cost lowered, but also the time on closing a valve in the coming of a tornado is less than 0.25s; therefore the damage caused by the tornado is furthest prevented; the cost is decreased greatly; due to no energy consumption of the executing mechanism, the energy is saved and the environment is protected; all functions are automatically finished, so that personal operation is needless.
Description
Technical field
The present invention relates to heating, ventilation, field of air conditioning, be specifically related to a kind of tornado valve operating gear.
Background technique
Existing spout air-valve is actuator's operation, and tornado carrys out interim valve closing shortest time 0.5 second, and the shut-in time is longer, and actuator is with high costs, and operating cost is large.
Summary of the invention
Goal of the invention: the present invention, in order to solve prior art deficiency, provides a kind of tornado valve operating gear.
Technological scheme: a kind of tornado valve operating gear, described operating device comprises main jib, secondary spiral arm, drive link and elastic component, described main jib is connected with drive link one end, and described elastic component is connected with the drive link the other end, and described main jib is provided with weight, on drive link between described main jib and elastic component, be connected with several secondary spiral arms, described main jib and secondary spiral arm are sleeved in rotating shaft.
As preferably, several secondary spiral arms are from top to bottom installed on described drive link.
As preferably, it is to be parallel to each other that the upper-lower position of described main jib and several secondary spiral arms closes.
As preferably, the number of described rotating shaft is several, and the number of described rotating shaft is identical with the number sum of main jib and secondary spiral arm.
As preferably, described main jib and secondary spiral arm all can be socketed in rotating shaft and rotate.
Beneficial effect: the present invention has replaced the former actuator involving great expense and complexity control system with spring and weight combined mechanism, not only reduce cost, and make valve be less than 0.25 second in the next interim shut-in time of tornado, prevent to greatest extent the harm that tornado causes, significantly reduce cost, there is no the energy consumption of actuator, energy-conserving and environment-protective, all functions all complete automatically, do not need personnel to operate.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is described in detail:
As shown in Figure 1, a kind of tornado valve operating gear, described operating device comprises main jib 2, secondary spiral arm 5, drive link 4 and elastic component 6, described main jib 2 is connected with drive link 4 one end, described elastic component 6 is connected with drive link 4 the other ends, described main jib 2 is provided with weight 1, is connected with several secondary spiral arms 5 on the drive link 4 between described main jib 2 and elastic component 6, and described main jib 2 is sleeved in rotating shaft 3 with secondary spiral arm 5; Several secondary spiral arms 5 are from top to bottom installed on described drive link 4; It is to be parallel to each other that described main jib 2 closes with the upper-lower position of several secondary spiral arms 5; The number of described rotating shaft 3 is several, and the number of described rotating shaft 3 is identical with the number sum of secondary spiral arm 5 with main jib 2; Described main jib 2 all can be socketed in rotating shaft 3 and rotate with secondary spiral arm 5.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
