Abstract
The utility model discloses a balanced contraction section used for universal ventilation device, which comprises a contraction section 1, a fastening ring 2 and a fixed ring 3; wherein, the fastening ring 2 is sleeve-connected on the upper end of the contraction section 1, and the fixed ring is arranged outside the lower end of the contraction section 1. The aspiration channel and the suspended hood in the air draft device can control the collapsing length according to the location of the toxic gas source, so as to determine the best location to expel the toxic gas, and then discharge air effectively, and keep the toxic gas entering and doing harm to human body; at the same time the chemical apparatuses can be arranged reasonably according to the specific conditions in the laboratories, so the utility model can make full use of the space and get free from the position restrictions of the suspended hood.
Description
The utility model relates to a kind of tubular union, especially a kind of balance contraction joint that can be used for connecting pipeline in the universal type ventilation plant.
It has been recognized that when the chemical experiment of studying and imparting knowledge to students; regular meeting discharges the toxic gas harmful to health; influence research is normally carried out with teaching; for this reason; people install ventilation plant usually in the chemical experiment place, suck toxic gas farthest to avoid the chemical experiment personnel.If any the laboratory unidirectional ventilating fan has been installed on window, though unidirectional ventilating fan can in time be discharged the toxic gas that produces in the laboratory, toxic gas but has the process of filling the air indoor, still can enter human body in large quantities; The laboratory that has then is that ventilation plant has been installed, by forcing the air draft mode, in time discharge the toxic gas that chemical experiment produced, though this ventilation plant is than unidirectional ventilating fan advanced person, but existing ventilation plant, the length of its ventilation duct cannot be stretched arbitrarily, is changeless, like this, just, fixed the relative position of suction hood.Because suction hood must be arranged on the optimum discharge distance, could produce best effect of ejecting poison, therefore, the chemical experimental instrument assembling position will be subjected to the qualification of suction hood position, uses very inconvenience.
The purpose of this utility model provides a kind of suction pipe or random collapsing length of suction hood of making, and shrinks joint with the universal type ventilation plant of determining best air draught position with balance.
Technical solution of the present utility model is:. a kind of universal type ventilation plant shrinks joint with balance, is provided with to shrink joint 1, is socketed with fastening ring 2 in the upper end of shrinking joint 1, and the outside, lower end of shrinking joint 1 is provided with retainer ring 3.
Described contraction joint 1 can be provided with contraction mouth 4 with the port of fastening ring 2 sockets.
Described contraction mouth 4 can be the striated contraction mouth.
Shrinking joint 1 can be with fastening ring 2 and is threaded.
Shrinking joint 1 also can be with retainer ring 3 and is threaded.
Shrinking joint 1, fastening ring 2, retainer ring 3 is made by ABS plastic.
Technological scheme disclosed in the utility model can make suction pipe in the ventilation plant and suction hood according to the random collapsing length in the position of poisonous source of the gas, to determine best toxin expelling position, reach best air draft effect, avoid toxic gas to enter human body, human body is damaged, simultaneously, chemical apparatuses also can be according to breadboard actual conditions rational deployment, utilize sky to ask as much as possible, need not to be subjected to again the qualification of suction pipe and suction hood position, very convenient.
Fig. 1 is the utility model embodiment's a schematic representation.
Fig. 2 is the schematic representation that shrinks joint among the utility model embodiment.
Fig. 3 is the schematic representation of fastening ring among the utility model embodiment.
Fig. 4 is the schematic representation of retainer ring among the utility model embodiment.
Below in conjunction with accompanying drawing and specific embodiment of the utility model the utility model is further described.Shown in Fig. 2,3,4, contraction 1, fastening ring 2, retainer ring 3 all can be made by ABS plastic, fastening ring 2 is enclosed within the upper end of shrinking joint 1 and saves 1 with contraction and is threaded, the port of shrinking joint 1 and fastening ring 2 sockets can be provided with striated contraction mouth 4, the outer ring, lower end of shrinking joint 1 retainer ring 3 that is threaded.
During use, suction pipe or suction hood are plugged on the upper end and the lower end of shrinking joint 1 respectively, adjust fastening ring 2, retainer ring 3, make suction pipe or suction hood can be in shrinking joint 1 relative movement and not disconnecting, twitch suction pipe or suction hood, can change the length of suction pipe or suction hood, thereby determine the position of suction hood.
The utility model promptly can be applicable in the air exhausting device, also can be used as balance shrink joint and be applied in any need connecting pipeline and needs change pipeline length other install.
