Abstract
An automatic liquid discharge valve of a pipe consists of a valve body and a sealing steel ball with a return spring arranged in the valve. The return spring is arranged between the sealing steel ball and a liquid discharge mouth of the valve body. A sealing ring which is matched with the sealing steel ball is arranged on a valve seat which is arranged on the side of the liquid discharge mouth. A liquid inlet is matched with the sealing steel ball in a clearance way. When the water supply of the utility model is normal, the sealing stops, when the phenomenon of the blockage and no water happens, the liquid discharge mouth can be opened automatically to discharge the residual water in an emptying pipe. The utility model has simple structure, reliable action and good use effect.
Description
Technical field: the utility model relates to a kind of cut-off type valve.
Background technique: in the colder area of weather, if situations such as blocking, cut off the water appears in supply channel during winter, the interior residuary waters of pipeline can freeze rapidly, brings sizable inconvenience to maintenance.Some pipeline is equipped with manual liquid discharging valve, is used for the emptying residuary waters, but situation generally can not be found processing rapidly, so manual liquid discharging valve using effect is relatively poor.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of pipeline selfdraining valve that can automatically emptying residuary waters.
The utility model comprises valve body and the sealed steel ball of the band Returnning spring that is placed in one, this Returnning spring is located between the liquid port of sealed steel ball and valve body, the seal ring that matches with sealed steel ball is located on the valve seat of discharge opeing oral-lateral, the liquid entering hole of valve body then with the sealed steel ball Spielpassung.
When supplying water just often, sealed steel ball is pressed to seal ring under the liquid entering hole hydraulic action, and liquid port is sealed to be ended, and when the unusual hydraulic pressure that supplies water was not enough, Returnning spring backed down sealed steel ball, and liquid port is unimpeded, and ducted residuary waters is by emptying rapidly.Of the present utility model simple in structure, reliable in action, using effect is good.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is embodiment's a structural representation.
Embodiment: as shown in the figure, valve body 1 is built-in with the sealed steel ball 2 of band Returnning spring 3, this Returnning spring 3 is located between the liquid port 5 of sealed steel ball 2 and valve body 1, the seal ring 4 that matches with sealed steel ball 2 is located on the valve seat of liquid port 5 sides, 6 of liquid entering holes of valve body 1 and sealed steel ball 2 Spielpassung.Present embodiment is provided with divider 7 at liquid entering hole 6 places, and retaining pin 8 and sealed steel ball 2 that this divider 7 is provided with hook in several cooperate the big gap structure of formation, sealed steel ball 2 is not had with liquid entering hole 6 directly contact, and the gap of cooperation is quite big, and discharge opeing is rapider.Can establish connecting thread 9 on the surface of valve body 1, can make things convenient for like this with the installation of pipeline to be connected.
