Accompanying drawing explanation
Fig. 1 is that the utility model sealing and connecting device examines the structural representation of an embodiment when installing tube-like piece;
The detonation configuration schematic diagram that Fig. 2 is the sealing and connecting device shown in Fig. 1 and tube-like piece.
The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides the sealing and connecting device of tube-like piece, and with reference to Fig. 1, in one embodiment, sealing coupling arrangement comprises fixture 1, first end cap 3 and the second end cap 4.For convenience of explanation, the present embodiment is mounted to the state of sealing and connecting device so that sealing coupling arrangement to be described with tube-like piece 7.In the present embodiment, described tube-like piece 7 adopts ultra-filtration element to describe in detail, and tube-like piece 7 comprises for intaking and the two ends of water outlet, is respectively first end 71 and the second end 72.In other embodiments, described tube-like piece 7 also can be ultra-filtration water purifier or other tube-like pieces.Wherein ultra-filtration water purifier comprises ultra-filtration element and shell, and described ultra-filtration element is wrapped in described shell; Described shell is generally stainless steel products.
Described first end cap 3 comprises the first noumenon 31, and described the first noumenon 31 offers the first connector (mark), the second connector 32 and is connected the through hole (mark) of described first connector and the second connector 32; The blind hole 42 that described second end cap 4 comprises the second body 41 and is located on described second body 41.
First connector of described first end cap 3 is used for being tightly connected with the first end 71 of described tube-like piece 7, second connector 32 of described first end cap 3 is for being tightly connected with the source of the gas (mark) of outside, in the present embodiment, the second connector 32 is tightly connected by pipeline 6 and outside source of the gas.The blind hole 42 of described second end cap 4 is for being tightly connected with the second end 72 of described tube-like piece 7.Described fixture 1 for when described tube-like piece 7 receives the air pressure of described source of the gas and described first end cap 3 and the second end cap 4 inconsistent, be separated with the two ends of tube-like piece 1 respectively with the second end cap 4 to prevent described first end cap 3.
In the present embodiment, tube-like piece 7 is linearity, and in other embodiments, tube-like piece 7 also can be curve-like.
Above-mentioned sealing and connecting device, in use, the second end 72 of tube-like piece 7 can block by the second end cap 4, and the first end 71 of tube-like piece 7 is connected with outside source of the gas by the first end cap 3.And when described fixture 1 can avoid the air pressure in tube-like piece 7 to increase, the second end cap 4 departs from the second end 72 of tube-like piece 7.Thus make in gas leakage detects, source of the gas, tube-like piece 7, first end cap 3 and the second end cap 4 are combined as airtight with a stable cavity, and then can be judged the impermeability of tube-like piece 7 by the situation of change of the air pressure in monitoring tube-like piece 7.Particularly, if tube-like piece 7 exists leakage point, then the air pressure in tube-like piece 7 will reduce.Therefore, can judge to show whether tube-like piece 7 leaks gas by above-mentioned change.
Above-mentioned sealing and connecting device can adopt the first end cap 3 of plurality of specifications.Wherein the size shape of the second connector 32 of the first end cap 3 of plurality of specifications is consistent, to be connected with outside source of the gas by same flexible pipe; The size shape of the first connector 31 of the first end cap 3 of plurality of specifications is multiple, to adapt to the different size of tube-like piece 7.Therefore, the tube-like piece 7 going for different size of above-mentioned sealing and connecting device, has stronger versatility.
In order to make tube-like piece be connected with the first end cap and the second end cap seal, surface of contact in-between can arrange O-ring seal.
In the present embodiment, because tube-like piece 7 is ultra-filtration elements, therefore, the outer peripheral face of its first end 71 the second ends 72 is all provided with O-ring seal 711,721.In order to closely cooperate with above-mentioned O-ring seal 711,721, particularly, the inside surface forming described through hole in described the first noumenon 3 is light face, and the inside surface forming described blind hole 42 in described second body 4 is light face.First end cap 3 of above-mentioned sealing and connecting device and the second end cap 4 coordinate tightr with the two ends 71,72 of tube-like piece 7, thus are not easy to gas leakage, make the measurement of air leakage checking system more accurate.
Certainly, in other embodiments, the face that first end 71 and second end 72 of tube-like piece 7 contact with the second end cap 4 with the first end cap 3 respectively also can be light face; The inside surface then forming described through hole in described the first noumenon 3 can be arranged with the first ring groove to hold O-ring seal, the inside surface forming described blind hole in described second body can be arranged with the second ring groove to hold O-ring seal.Thus the first end 71 of tube-like piece 7 and the second end 72 are sealed and matched with the first end cap 3 and the second end cap 4 respectively.
Particularly, the first noumenon 31 of described first end cap 3 comprises round plate 311, first pipe portion 312 and the second pipe portion 313, and described first pipe portion 312 and the second pipe portion 313 are connected to the relative both sides of described round plate 311 and extend dorsad; Described first connector is located in described first pipe portion 312, and described second connector 32 is located in described second pipe portion 313.First connector in described first pipe portion 312 is used for inserting for described tube-like piece 7 first end 71, and described round plate 311 is for conflicting with described tube-like piece 7; Described first pipe portion 312, for inserting the pipeline 6 be connected with described source of the gas, is communicated with described pipeline 6 to make the first connector be positioned in described first pipe portion 312.The round plate 311 of the first above-mentioned end cap 3 is easy to operating personnel's operation, can also in installation with in using, avoid the first end 71 of tube-like piece 7 when tube-like piece 7 receives the air pressure of source of the gas directly and fixture 1 collide and wound.
Similar with the first end cap 3, particularly, second body 41 of described second end cap 4 comprises the second round plate 311 and the 3rd pipe portion 412, described 3rd pipe portion 412 is located at the side of described second round plate 311, and the blind hole 42 of described second body 41 is extended towards described second round plate 311 by described 3rd pipe portion 412; Described blind hole 42 is inserted for the second end 72 for described tube-like piece 7, described second round plate 311 is for conflicting with described tube-like piece 7, to avoid in installation with in using, the second end 72 of tube-like piece 7 when tube-like piece 7 receives the air pressure of source of the gas directly and fixture 1 to collide and wounded.
