Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Below in conjunction with embodiment and detailed description of the invention, the present invention is further detailed explanation.
As depicted in figs. 1 and 2, a kind of elbow check-valves, include L-shaped valve body 1 and the spheroid non-return valve core 2 being placed in valve body, described valve body 1 is made up of the upper valve body 11 being mutually adapted and lower valve body 12, the inwall of described upper valve body 11 is evenly distributed with several block reinforcement 3, the other end of described upper valve body 11 is water side, described water side is connected to outlet pipe 4, the other end of described lower valve body 12 is water inlet end, described water inlet end the great circle size being smaller in size than described spheroid non-return valve core, described water inlet end is connected to water inlet pipe 5.
The present invention makes this device have the function of pipeline bending and current non-return by valve body, water inlet pipe and outlet pipe, reduces the purpose of the work load of production cost and reduction staff.
It should be noted that described upper valve body 11 and lower valve body 12 are equipped with connection lug 13, described connection lug 13 is provided with and is connected bolt 14 that lug matches and nut 15, described upper valve body and lower valve body are achieved a fixed connection by connection lug, screw bolt and nut.
It should be noted that the junction of described upper valve body and lower valve body is provided with O RunddichtringO 16.The present invention is made to have good air-tightness.
It should be noted that and be evenly distributed with three block reinforcements on described upper valve body inwall, the bottom of described block reinforcement is fixedly connected on the inwall of described upper valve body, and the diameter of a circle that the top of described block reinforcement is formed is less than the axis of great circle of described spheroid non-return valve core.
It should be noted that and described outlet pipe is connected to the first loose flange 6, between described outlet pipe and the first loose flange, be provided with flange anticreep jump ring 7；Described water inlet end is connected to water inlet pipe, and described water inlet pipe is connected to the second loose flange 8, also is provided with flange anticreep jump ring between described water inlet pipe and the second loose flange.Prevent the first loose flange and the second loose flange from coming off by flange anticreep jump ring.
It should be noted that described outlet pipe and adopt integration to produce with upper valve body；Described water inlet pipe and lower valve body adopt integration to produce.
The specifically used step of the present invention is as follows: more as depicted in figs. 1 and 2, before enforcement, upper valve body 11 and outlet pipe 4 adopt integration to produce, lower valve body 12 and water inlet pipe 5 adopt integration to produce, by connecting lug 12, bolt 12 and nut 15, upper valve body 11 and lower valve body 12 are achieved a fixed connection, and the sealing of valve body 1 is ensured by O RunddichtringO, water inlet pipe realizes being connected with external pipe by the second loose flange 8 and flange anticreep jump ring 7, and outlet pipe 4 is connected by the pipeline of the first loose flange 6 with flange anticreep jump ring 7 with outside other direction.During enforcement, during extraneous starting mode of pump, current are entered valve body by water inlet pipe, wash spheroid non-return valve core 2 open, until spheroid non-return valve core 2 arrives block reinforcement 3 place, now current are entered in outlet pipe by the gap between spheroid non-return valve core 2 and valve body 1, when extraneous water pump quits work, spheroid non-return valve core 2 is pushed back the water inlet end of lower valve body 12 by hydraulic pressure again, it is achieved that check function, prevent water hammer from equipment is caused damage, extend the service life of equipment.
Above-described is only the preferred implementation of elbow check-valves disclosed in this invention; it should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also making some deformation and improvement, these broadly fall into protection scope of the present invention.
