Abstract
The utility model relates to the field of pipeline valve technology, specifically to an eccentric half-ball valve comprising a valve body formed by a first half valve and a second half valve. One side of the valve body is provided with a liquid inlet and the other side of the valve body is provided with a liquid outlet. A half-ball valve plug is disposed in the valve body and the upper end and the lower end of the half-ball valve plug are disposed on the valve body through rotary shafts. One rotary shaft extends out of the valve body. The inner wall of the valve body is provided with a projection at the liquid outlet. The half-ball valve plug is provided with a seal groove into which the projection is inserted. A filtering element is disposed in the valve body and the half-ball valve plug and the filtering element are switched for filtrating a medium passing through the liquid outlet. The eccentric half-ball valve is simple in structure and is convenient for installation and detachment. In an off state, the sealing effect is good; and in an on state, the eccentric half-ball valve can filter the medium passing therethrough.
Description
Technical field
The utility model relates to the pipeline valve technical field, is specifically related to a kind of eccentric half-ball valve.
Background technique
Eccentric half-ball valve and Flange Gate Valves are the valves that belongs to a type together, and difference is a spheroid at its closure member, and spheroid makes around the valve body center line a kind of valve that rotation reaches unlatching, closes.The flow direction that ball valve is mainly used to make cut-out, distributes and change medium in pipeline.Existing eccentric half-ball valve comprises the spool in integrated valve body, valve body, the rotation of spool can be carried out shutoff to the liquid entering hole of valve body, but place does not have sealing configuration due to liquid entering hole, can not well seal liquid entering hole like this, Seepage easily appears; In addition, valve body one-body molded arranges inconvenience to the installation of spool and maintenance, maintenance to valve body; In addition, valve, after cut-out converts unimpeded state to, needs to adopt filter element to be filtered the medium entered.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of eccentric half-ball valve of simple in structure, easy installation and removal, and it is when dissengaged positions, and good sealing effect, when unimpeded state, can be filtered the medium through wherein.
Realize that the technical solution of the utility model is as follows:
Eccentric half-ball valve, comprise the valve body be combined into by the first half valve bodies, the second half valve bodies, one side of valve body is provided with liquid entering hole, opposite side is provided with liquid outlet, be provided with the hemisphere spool in valve body, the two ends up and down of hemisphere spool are arranged on valve body by rotating shaft respectively, and wherein the outside of valve body is extended in a rotating shaft, valve interior wall at liquid entering hole is provided with projection, is provided with the seal groove inserted for projection on the hemisphere spool; Be provided with in valve body with the hemisphere spool and switched the filter element that the medium through liquid entering hole is filtered.
Further, described filter element comprises the framework be fixedly installed between above-mentioned rotating shaft, and is arranged in the filter screen in framework.When rotating shaft is rotated, framework can be followed rotating shaft and be rotated together; When the hemisphere spool is the valve body cut-out to valve body liquid entering hole formation sealing, filter element is positioned at hemisphere spool one side, when make the hemisphere spool leave liquid entering hole by rotating shaft, while making liquid entering hole and liquid outlet conducting, filter element rotates to the liquid entering hole position, wherein, framework gets lodged in around liquid entering hole, and the filter screen in framework just can be filtered the medium entered from liquid entering hole.
Further, be provided with the frame seal groove inserted for above-mentioned projection on described framework.After projection in valve body is inserted the frame seal groove like this, form sealing between framework and valve body, prevent that medium is from seepage between valve body and framework.
Further, between described the first half valve bodies, the second half valve bodies, be bolted together, and the fitting surface place between the first half valve bodies and the second half valve bodies is provided with seal ring.Very convenient when installation, dismounting; Simultaneously due to the setting of seal ring, guaranteed not there will be seepage between the first half valve bodies, the second half valve bodies.
Adopted above-mentioned scheme, valve body is combined by the first half valve bodies, the second half valve bodies, is convenient to be installed on dismounting; And be provided with projection near liquid entering hole in valve body, and be provided with the seal groove inserted for projection on the hemisphere spool, after projection is inserted seal groove, form between valve body and hemisphere spool and seal, the medium in liquid entering hole is just by by passing through like this; And filter element is set in rotating shaft, and leaving liquid entering hole at the hemisphere spool, after the unimpeded state of liquid entering hole and liquid outlet, filter element can rotate to the liquid entering hole position, and the medium through liquid entering hole is filtered.The utility model is simple in structure, easy installation and removal, and when dissengaged positions, good sealing effect, when unimpeded state, can be filtered the medium through wherein.
