Fig. 2 is the blast structural representation of the utility model drainage arrangement;
Fig. 3 is the cross-sectional view of crossing the water lining in the utility model drainage arrangement.
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Be described further with regard to the technical solution of the utility model below in conjunction with drawings and the specific embodiments.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of drainage arrangement.
Referring to figs. 1 through Fig. 3, Fig. 1 is the cross-sectional view of the utility model drainage arrangement; Fig. 2 is the blast structural representation of the utility model drainage arrangement; Fig. 3 is the cross-sectional view of crossing the water lining in the utility model drainage arrangement.
In the present embodiment, drainage arrangement is applied in the electric heater, be arranged on the inner bag bottom of electric heater, it specifically comprised water lining 10, magnesium rod 20 and ball valve 30, this is crossed water lining 10 and arranges in a tubular form, its sidewall is provided with at least one apopore 11, and this end of crossing water lining 10 is connected with magnesium rod 20, and the other end is connected with ball valve 30.
When the user need to carry out draining to the electric heater that drainage arrangement is installed, open the switch 32 that arranges on the ball valve 30, water in the inner bag of electric heater can pass through the apopore 11 on the water lining 10, stream process water lining 10 and ball valve 30, thus be discharged to the electric heater outside, can open simultaneously in case of necessity the water inlet of electric heater, inner bag to electric heater cleans, when water drained or clean complete after, close ball valve 30, can normally use.
Drainage arrangement of the present utility model is simple in structure, easy to assembly, need not to adopt specific purpose tool can realize inner bag draining and the cleaning of electric heater, whole draining or cleaning process are simple and convenient, can finish under without professional person's operation, are fit to average family and use.
In the above-described embodiments, the end that mistake water lining 10 is connected with ball valve 30 is provided with outside flange 12, and the outer ledge of this flange 12 is provided with external screw thread 13.Ball valve 30 is provided with a connection piece 31, and the inwall of this connector 31 is provided with the internal thread (not shown), and the external screw thread 13 on this internal thread and the flange 12 is adaptive, cooperates with external screw thread 13 by internal thread, and water lining 10 was threaded with ball valve 30.
Be threaded with ball valve 30 by crossing water lining 10, so that the more convenient assembling of drainage arrangement and dismounting have improved production efficiency.When maintenance, the cost of labor when having reduced maintenance can directly ball valve 30 be backed out from crossing water lining 10.
In the above-described embodiments, one end of magnesium rod 20 is provided with threaded column 21, crosses water lining 10 and is provided with screwed hole 14 with magnesium rod 20 ends that are connected, and this threaded column 21 is adaptive with screwed hole 14, cooperate with screwed hole 14 by threaded column 21, magnesium rod 20 is threaded with mistake water lining 10.
Based on above-described embodiment, this drainage arrangement also can comprise a sealing gasket 40, and sealing pad 40 was clamped between the end face and ball valve 30 that water lining 10 is connected with ball valve 30.Sealing pad 40 is preferably rubber blanket.
The setting of sealing pad 40 was tightly connected water lining 10 and ball valve 30, had avoided water in the inner bag of electric heater from crossing the junction seepage of water lining 10 and ball valve 30, cause getting rusty, corrode, thus the service life of reduction water heater.
Based on above-described embodiment, this drainage arrangement also can comprise a sealing ring 50, and sealing circle 50 was arranged in the groove 15 that the outer wall of water lining 10 offers, and is clamped between the inwall of the outer wall of water lining 10 and connector 31.
