Abstract
The utility model discloses an air bleeding ball valve, including the ball valve body, install intake pipe and outlet duct on the ball valve body, the intake pipe is kept away from one of ball valve body and is served and install the ring flange, the outlet duct is kept away from one of ball valve body and is served the spiral shell and close to install and filter the lid, ball valve body internally mounted has the spheroid, the inside air vent of having seted up of spheroid, the fixed slot has been seted up on the spheroidal lateral surface, set up flutedly on the lateral surface of ball valve body, install the dust ring in the recess, the through -hole has been seted up in the recess, the one end of through -hole with the spheroid links to each other, install the connecting rod in the through -hole. The utility model discloses an air bleeding ball valve installs the dust ring between connecting rod and the ball valve body, increase the leakproofness of ball valve to it gets into inside the ball valve to reduce the dust, install on the outlet duct and filter the lid, can reduce the impurity among the exhaust gas, reduce the pollution to the environment.
Description
technical field:
The utility model relates to a kind of venting ball valve.
background technique:
Ball valve all presents sphere at inlet/outlet place, thus block flowing.Because it is tight that ball valve only needs the operation of 90-degree rotation and very little moment of rotation just can close, and the runner that the body cavity opened completely to be medium provide resistance is very little, straight-through, have and be suitable for directly doing opening and closing use, also can be used as the use of throttling and control flow.Particularly its compact structure, is easy to Operation and maintenance, is applicable to water, solvent, acid and rock gas working medium.But the most volume of existing ball valve is excessive, structure is too complicated, and function singleness, sealing are poor, all cannot be suitable in a lot of occasion.
summary of the invention:
The purpose of this utility model is to solve the problems of the prior art, provides that a kind of structure is simple, good airproof performance, and has the venting ball valve of filtering function.
In order to achieve the above object, the technical solution of the utility model is:
A kind of venting ball valve, comprise ball valve body, described ball valve body is provided with suction tude and steam outlet pipe, described suction tude is provided with flange plate away from one end of ball valve body, and described steam outlet pipe is provided with filtering cover away from one end of ball valve body screws togather; Described ball valve body inside is provided with spheroid, and described ball interior offers vent, and the outer side surface of described spheroid offers fixed groove; The outer side surface of described ball valve body offers groove, is provided with dust ring in described groove, offer through hole in described groove, one end of described through hole is connected with described spheroid; In described through hole, connecting rod is installed.
In the middle of described connecting rod, integrally manufactured retaining ring is installed, described retaining ring one lateral connector bar offers screw thread, described connecting rod is movably installed with set screw nut by screw thread; Described retaining ring is provided with fixing pin away from one end of screw thread, and described fixing pin is connected with fixed groove.
Described filtering cover is provided with filter screen, and the diameter of described filter screen is identical with the internal diameter of described steam outlet pipe.
The internal diameter of described dust ring is identical with the external diameter of described connecting rod.
The beneficial effects of the utility model are: a kind of venting ball valve of the present utility model, is provided with dust ring between connecting rod and ball valve body, increase the sealing of ball valve, and reduce dust and enter ball valve inside; Steam outlet pipe is provided with filtering cover, the impurity in Exhaust Gas can be reduced over, reduce the pollution to environment.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
Embodiment 1
