Abstract
The utility model discloses a membrane shell sealing piece of a tubular pressure container used for reverse osmosis water treatment equipment. The membrane shell sealing piece comprises a membrane shell sealing piece body, a large sealing ring and a small sealing ring, wherein the membrane shell sealing piece needs sheathing in the middle of a sheathed part of a pressure pipe to form an inclined plane structure, and the small sealing ring is arranged under the inclined plane structure; the bottom of the sheathed part of the membrane shell sealing piece is provided with a groove, and the large sealing ring is arranged in the groove. The utility model adopts the inclined plane structure to replace the traditional plane structure. The small sealing ring can rise towards the inclined plane structure with the increase of pressure. The seal is tighter when the pressure is larger.
Description
Technical field
The utility model relates to the putamina sealing member of the tubular pressure container that a kind of reverse osmosis water treating equipment uses.
Background technology
At present, the putamina sealing member of the tubular pressure container that water treating equipment are commonly used, its structure is as shown in Fig. 1, Fig. 2.Putamina sealing member on Fig. 1 is that employing has two grooves 1,2 at position, the plane C that the putamina sealing member will be inserted in the pressure body, puts in twice groove 1,2 and puts into two sealing- rings 3,4 respectively, produces sealing effectiveness by encapsulating with putamina then.Putamina sealing member on Fig. 2 is to have groove 5 one in position, the plane D bottom that the putamina sealing member will be inserted in the pressure body, puts into a sealing-ring 6 in groove 5, produces sealing effectiveness by encapsulating with putamina then.Aforesaid two kinds of sealing members, in use also there are the following problems, putamina sealing member as shown in Figure 1, when mounted, the putamina sealing member is not easy to be inserted in the penstock, generally need beat to apply certain power and just can finish on the part body, so just makes the sealing member easy deformation, influence sealing effectiveness, and be inconvenient to dismantle.Sealing member as shown in Figure 2 though can play more convenient installation, has only a sealing-ring, and sealing effectiveness is undesirable, easily infiltration.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, and a kind of good sealing effect, easy-off putamina sealing member are provided.
In order to achieve the above object, technical solution adopted in the utility model is: include a putamina seal body, large sealing packing ring, small sealing ring composition, the socket part intermediate formation that will be inserted in penstock at the putamina sealing member has a ramp structure, small sealing ring is positioned over the below of this ramp structure, have groove one in bottom, putamina sealing member socket part, large sealing packing ring is positioned in this groove.
The beneficial effects of the utility model are, have adopted ramp structure to substitute traditional two dimensional structure in the socket part of putamina sealing member, when mounted, are easy to just can pack into the tubular pressure container.In the use, because the pipe internal pressure produces, small sealing ring rises to ramp structure with the increase of pressure, and pressure is big more, seal tightly more, reaches the sealing effectiveness of the best.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model is further set forth, as shown in Figure 3, the utility model includes a putamina seal body 11, large sealing packing ring 12, small sealing ring 13 compositions, the socket part a intermediate formation that will be inserted in penstock at putamina sealing member 11 has a ramp structure b, small sealing ring 13 is positioned over the below of this ramp structure b, have groove 14 one in putamina sealing member 11 socket part a bottom, large sealing packing ring 12 is positioned in this groove 14.After finishing said structure, be installed on the tubular pressure container by industry maturation process, the added metal limit collar is fixing can be used, and mounting means adopts existing technology, does not do at this and gives unnecessary details.
