Abstract
The utility model discloses a tornado valve operation mechanism which comprises a main rotating arm, auxiliary rotating arms, a transmission rod and an elastic piece. The main rotating 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 hammer is arranged on the main rotating arm. The auxiliary rotating arms are connected to the transmission rod between the main rotating arm and the elastic piece. The main rotating arm and the auxiliary rotating arms are arranged on a rotating shaft in a sleeved mode. According to the tornado valve operation mechanism, a spring and heavy hammer combination mechanism is used for replacing an original executing mechanism high in manufacturing cost and a complexity control system, cost is lowered, the closing time of a valve is shorter than 0.25 s when a tornado comes, damage caused by the tornado is prevented to the maximum degree, cost is greatly lowered, energy consumption of the executing mechanism is avoided, energy is saved, environment is protected, all functions are achieved automatically, and personnel operation is of no need.
Description
Technical field
The utility model relates to heating, ventilation, field of air conditioning, is 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.
Model utility content
Model utility object: the utility model, 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 utility model 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 utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment 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 preferred implementation of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
