Abstract
The utility model relates to a ball valve, which comprises a body and a spool. The body is provided with a cavity, and a water inlet and a water outlet which are communicated with the cavity. The spool is arranged in the cavity and provided with a through flow channel and a drainage opening communicated with the flow channel and the outside of the spool, height of the bottom of the drainage opening is equal to or smaller than that of the bottom of the flow channel, and when the ball valve is closed, the drainage opening is communicated with the flow channel and the water outlet of the body. When the ball valve is closed, the drainage opening additionally disposed on the spool discharges fluid in the flow channel of the spool out of the same, thereby improving use performance and service life of the ball valve compared with conventional ball valves.
Description
Technical field
The utility model relates to the valve technology, relates in particular to a kind of ball valve.
Background technique
Ball valve is developed by cock, is mainly used in cut-out on pipeline, distributes and changes the media flow direction.The open-shut device of ball valve is that spool is a spheroid, and spool has perforation runner wherein.Water intake and water outlet that valve body has the valve pocket that is used for ccontaining spool and is communicated with this valve pocket.Make spool and valve body be in the opening and closing that different relative positions is realized ball valve by rotational valve core.When the runner of valve core rotation on making it was communicated with the water intake of valve body and water outlet position, ball valve was opened, and fluid flows through spool from water intake, spool runner and the water outlet of valve body successively; When the runner of valve core rotation on making it during not with position that water intake and water outlet are communicated with, ball valve is closed, and fluid can not pass through ball valve.This ball valve since when closing the runner of spool all be not communicated with the water intake and the water outlet of valve body, the fluid in the runner remains in the spool and can not in time discharge.If ball valve uses when high temperature or low temperature environment, the residual fluid in the spool runner can expand or freeze because of cold because of heat, thereby reduces the usability of ball valve and reduce the life-span.
Summary of the invention
Technical problem to be solved in the utility model is that spool does not have the ball valve of residual fluid when proposing a kind of closing.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of ball valve, comprise valve body and spool, valve body has valve pocket and is communicated with the water intake and the water outlet of this valve pocket, spool is arranged in the valve pocket and has the runner of perforation, and spool also has the drain opening that is communicated with runner and spool outside, and the bottom of this drain opening and the bottom of runner are contour or be lower than the bottom of runner, when ball valve was closed, drain opening was communicated with the water outlet of runner and valve body.
The utility model has been set up drain opening on spool, when ball valve was closed, this drain opening was discharged the fluid in the spool runner outside the spool, compares usability and life-span that existing ball valve has improved ball valve.
Description of drawings
Fig. 1 is the stereogram of the utility model ball valve;
Fig. 2 is in the sectional view of enable possition for the utility model ball valve;
Fig. 3 is in the sectional view of closed position for the utility model ball valve;
Fig. 4 is a spool stereogram of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in detail.
Embodiment
Referring to Fig. 2, valve body 1 inside is provided with valve pocket, and valve body 1 has water intake 12 and the water outlet 13 that is communicated with this valve pocket.Spool 2 and valve seat 3 are placed in this valve pocket.Valve seat 3 materials are teflon, are clipped between the outer surface and valve pocket wall of spool 2, are used for sealing between valve body 1 and spool 2.Referring to Fig. 4, spool 2 is roughly spherical, and its top sphere is provided with mounting groove 21, and has runner 22 in the middle.Runner 22 connects whole spool, is the manhole coaxial with the spool medial axis, is used for passing through spool 2 for fluid when ball valve is opened.Spool 2 also is provided with the drain opening 23 that is communicated with runner 22 and spool 2 outsides, and drain opening 23 is a manhole.When ball valve is closed (as shown in Figure 3), drain opening 23 is communicated with runner 22 and water outlet 13.Referring to Fig. 2 and Fig. 3, when ball valve installs when being in the working position, the bottom of the bottom of drain opening 23 and runner 22 is contour.Like this, when ball valve was closed, the fluid in runner 22 was because action of gravity is flowed out spool 2 by drain opening 23.Referring to Fig. 1 and Fig. 2, valve rod 4 connects with spool 2 by mounting groove 21, and valve rod 4 connects handle 5.Make valve rod 4 and spool 2 rotational by handle with sleeve 5, thereby realize the opening and closing of ball valve around valve rod 4.
Referring to Fig. 2, when ball valve was opened, runner 22 was communicated with the water intake 12 and the water outlet 13 of valve body 1, and fluid flows through ball valve through water intake 12, runner 22 and water outlet 13 successively.Referring to Fig. 3, when ball valve was closed, spool 2 had been blocked the water intake 12 of valve body 1, and fluid can not enter spool 2, and the drain opening 23 of spool 2 is communicated with runner 22 and water outlet 13, and the fluid in the runner 22 is discharged spool 2 by drain opening 23.Like this, ball valve does not have unnecessary fluid in the spool when closing residual, avoided existing spool owing to the residual fluid in the runner expands or because of cold problem of freezing because of heat, thus the usability and the life-span of having improved ball valve.
The foregoing description only is used for the understanding to the utility model design, is not to restriction of the present utility model, and design can also have many structural simple change according to the utility model.For example, when ball valve installs when being in the working position, the bottom of drain opening 23 can also be lower than the bottom of runner 22, and drain opening 23 can also be the through hole of square or other shapes or the slit that is communicated with runner and spool outside.
