Abstract
The utility model discloses a sealing structure of central frame discharging tube of large-scale round sprayer, which comprises a fixed water tube and a rotary water tube mutually sheathed together. The sealing structure of central frame discharging tube of large-scale round sprayer is characterized in that 1-3 annular slots are arranged on the contact surface of the fixed water tube or the rotary water tube on the sheathed part; and the inside of each annular slot is equipped with a Y-shaped rubber seal ring. As the transverse elastic telescoping space of the Y-shaped rubber seal ring is large, the Y-shaped rubber seal ring has the advantages of wear resistance, long service life and hard leakage. The open end of the Y-shaped rubber seal ring faces to the direction of water pressure; the larger the water pressure is, the larger the opening dimension of the Y-shaped rubber seal ring is and then the larger the sealing effect is; therefore, the problem of easy water leakage due to over-large water pressure can not occur.
Description
Technical field
The utility model belongs to the irrigation machinery technical field, especially a kind of sealing configuration of large-scale circular irrigation sprinkler center rest outlet pipe.
Background technique
Large-scale circular irrigation sprinkler automaticity is high, the utilization ratio of water resources is high, circumference of an irrigation sprinkler rotation, and the soil of just can spray tens of mu even hundreds of mu, irrigation efficiency is very high, at present by extensive employing.The large-scale circular irrigation sprinkler comprises center rest and along some conduit pipes of striding that center rest moves in a circle, whenever strides and be equipped with several showers on the conduit pipe that the bottom of shower is provided with shower nozzle, whenever strides conduit pipe and all is fixed in the walking support of its underpart.
As shown in Figure 1; Described center rest comprises support 1 and outlet pipe; Outlet pipe comprises connect together each other fixedly water pipe 3 that is connected with water pump and the rotation water pipe 4 that is connected with conduit pipe, and the bottom of support installs and fixes water pipe 3, and rotation water pipe 4 is installed through sleeve 2 in the top of support.The fixedly water pipe 3 of socket need be provided with sealing configuration with rotation water pipe 4 at belled position each other; The sealing configuration of existing technology generally all adopts the rubber ring sealing; Because rubber ring generally adopts the solid torus structure, its elastic space is little, and service wear is fast; The operation of short time will be leaked, and changes rubber ring and bothers very much.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of sealing configuration of large-scale circular irrigation sprinkler center rest outlet pipe of simple in structure, good sealing effect is provided.
The purpose of the utility model is achieved in that a kind of sealing configuration of large-scale circular irrigation sprinkler center rest outlet pipe; Comprise the fixedly water pipe and rotation water pipe that connect together each other; It is characterized in that: belled position fixedly water pipe or the rotation water pipe surface of contact on 1～3 circular groove is set, in each circular groove the assembling Y type rubber seal.
As a kind of preferred scheme, belled position fixedly water pipe or the rotation water pipe surface of contact on 2 circular grooves are set.
The utility model is compared its advantage and is with existing technology: belled position fixedly water pipe or the rotation water pipe surface of contact on a plurality of circular grooves are set; In each circular groove, all assemble a Y type rubber seal; Because Y type rubber seal transverse elasticity extendable room is big; So it has wear-resistant, the advantage that grow, be not easy to leak service time.When assembling, the open end of Y type rubber seal is to the direction of hydraulic pressure, and the pressure of water is big more, and the open dynamics of opening of Y type rubber seal is just big more, and the effect of sealing is just big more, so can not occur because the excessive problem of leaking easily of hydraulic pressure.
Description of drawings

Fig. 2 is the fixedly water pipe and rotation water pipe belled position biopsy cavity marker devices perspective view of the utility model;
Fig. 3 is the Y type rubber seal biopsy cavity marker devices perspective view of the utility model;
Among the figure: the 1-support; 3-is water pipe fixedly; 4-rotates water pipe; The 2-sleeve; The 5-circular groove; 6-Y type rubber seal.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figures 2 and 3; A kind of sealing configuration of large-scale circular irrigation sprinkler center rest outlet pipe; Comprise the fixedly water pipe that connects together each other 3 and rotation water pipe 4, described fixedly water pipe 3 is enclosed within the outside of rotation water pipe 4, in the fixing inboard, upper end of water pipe 3 two circular grooves 5 is set; Y type rubber seal 6 of assembling in each circular groove 5, the opening end of Y type rubber seal 6 is downward.
Should be noted that at last; The content of above embodiment is only in order to explain the technological scheme of the utility model; But not to the restriction of the utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technological scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technological scheme.
Claims (2)
