Abstract
The utility model discloses a novel multi-sealed cleaning door which comprises a door frame, a door plate frame and a door plate. A contact surface between the door frame and the door plate frame is a curved surface, sealing strips are placed between the contact surface of the door frame and the door plate frame, and the outline of a cross section of the curved surface is a staircase curve which comprises at least four inflection points. The number of the sealing strips between the contact surface of the door frame and the door plate frame is two. Between the two sealing strips, the cross section of one sealing strip is larger than the cross section of the other sealing strip. According to the novel multi-sealed cleaning door, when different pressure levels exist on two sides of the door, reliable tightness of the door can be guaranteed, so that the air is prevented from flowing between the inner side and the outer side of the door (high and low pressure). The novel multi-sealed cleaning door can be widely applied on clean workshops such as food industry, medicine industry and electrical industry.
Description
Technical field
The utility model relates to a kind of seal door structure, relates in particular to a kind of novel multiple sealing clean door.
Background technology
At present, what use when having the different pressures grade in both sides all is single hermatic door, the structure of this door as shown in Figure 1, the door-plate frame 4 that comprises the doorframe 2 that is arranged on the body of wall 1, coincide with doorframe 2, be embedded with door-plate 5 in the described door-plate frame 4, the contact surface between described doorframe 2 and the described door-plate frame 4 is the cascaded surface of a turnover, and described doorframe is provided with weather strip 3 between the contact surface of described door-plate frame, owing to be subjected to the impact of machining accuracy, can not have reached hermetic effect in actual use.In addition, because manufacture craft restriction, many times the weather strip between door-plate and the doorframe can not effectively play sealing function, thereby can cause air from the slot leakage between weather strip and two side door plates or the doorframe, as shown by the arrows in Figure 1 airflow direction, leak to low-pressure side by the high-pressure side, not only cause the loss of Cooling and Heat Source, simultaneously in order to guarantee pressure reduction, then need the additional more air to the room, cause again the air-conditioner increase, brought the waste of electric energy.
The utility model content
For above-mentioned prior art, the utility model provides a kind of novel multiple sealing clean door, in the time of can having the different pressures grade in both sides, guarantee more reliably sealing function, prevent that air from flowing between the high and low pressure side of door, door of the present utility model can be widely used in the clean room of the industries such as food, medicine, electronics.
In order to solve the problems of the technologies described above, the technical scheme that a kind of novel multiple sealing clean of the utility model door is achieved is: comprise doorframe, door-plate frame and door-plate, contact surface between described doorframe and the described door-plate frame is curved surface, be provided with weather strip between the contact surface of described doorframe and described door-plate frame, the cross-sectional outling of described curved surface is staircase curve, and described staircase curve comprises four flex points at least.
Further, the utility model novel multiple sealing clean door, wherein, the weather strip between described doorframe and the described door-plate frame contact surface is the two seals bar; In the two seals bar, wherein the cross section of one weather strip is larger than the cross section of other one weather strip.
Compared with prior art, the beneficial effects of the utility model are:
Because the contact surface in the utility model between described doorframe and described door-plate frame is many turnover cascaded surfaces, and between the ladder contact surface of many turnovers, be provided with the two seals bar, when the both sides of door have the different pressures grade, can guarantee that this door has more reliably sealing, thereby prevent that air from flowing between the side of the innner and outer of door, door of the present utility model can be widely used in the clean room of the industries such as food, medicine, electronics.
Description of drawings
Fig. 1 is the structural representation of a kind of Cleaning door in the prior art;
Fig. 2 is the structural representation of a kind of novel multiple sealing clean of the utility model door;
Among the figure: 1-wallboard, 2-doorframe, 3-weather strip, 4-door-plate frame, 5-door-plate.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
As shown in Figure 2, a kind of novel multiple sealing clean door, comprise doorframe 2, door-plate frame 4 and door-plate 5, contact surface between described doorframe 2 and the described door-plate frame 4 is curved surface, be provided with weather strip between the contact surface of described doorframe 2 and described door-plate frame 4, the cross-sectional outling of described curved surface is staircase curve, for the better sealing problem that solves in different pressures grade Xiamen, described staircase curve comprises four flex points (and contact surface is made of many turnovers cascaded surface) at least, weather strip between described doorframe 2 and described door-plate frame 4 contact surfaces is two seals bar 3 when solving the individual layer weather strip and lost efficacy, the sealing problem of door; Also have, in order to remedy the error that produces in the processing, described weather strip 3 preferably adopts compressible seal; In the two seals bar, wherein the cross section of one weather strip is larger than the cross section of other one weather strip, can well play sealing function.
A kind of novel multiple sealing clean of the utility model door be that operating principle is: when door is closed, article two, weather strip 3 is compressed, play sealing function, if because door is done former thereby cause wherein one weather strip not effectively during compression, another road weather strip (referring to one weather strip that cross section is slightly large) is closing door body, as shown by the arrows in Figure 2 airflow direction effectively, can effectively air-flow be stoped in the high-pressure side, thereby, guaranteed the sealing of door body, prevent that air from leaking to low-pressure side.
Although the above is described the utility model in conjunction with figure; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that does not break away from the utility model aim, can also make a lot of distortion, these all belong within the protection of the present utility model.
Claims (3)
