Abstract

The utility model relates to a filtering ball valve for preventing dirt in a medium from accumulating in a pipe. Mainly, a filter casing is arranged in a valve ball communicating cavity of an ordinary ball check, and the side wall of a valve body is provided with a sewage draining exit. When the ball valve is closed, the filter casing is just opposite to the sewage draining exit; as long as a pipe closer of the sewage draining exit is opened, dirt in the pipe closer can be cleared away. The utility model has the advantages of reasonable structure, convenient installation and blowdown, low cost, etc. and can be widely used in a pipeline system in medicine, chemical engineering, refrigeration, metallurgy, etc.

Description

Filtering ball valve

The utility model relates to a kind of valve that conveyance conduit opens and closes of controlling, and particularly can prevent the Filtering ball valve that dirt in the medium or other impurity accumulate in pipe.

At present, move the machine or the parts of working in pipe-line system by flowing medium, the purity of convection cell all has certain requirement, in order to prevent fluid dirt deposition or to the influence of machine part on pipeline, be everlasting filter member be installed on the pipeline in addition, as on August 12nd, 1998 bulletin the patent No. be 97213508, name is called the " patent of piping filter.But this type of filter member all will be on pipeline mounted valve, this just makes troubles to installation, and has increased cost.

The purpose of the utility model is to provide a kind of impurity in can the filter pipe medium, can make things convenient for the ball valve of blowdown again.

The technical solution of the utility model is such: it by three way valve, be contained in sealing seat in the valve body, valve ball, valve rod, valve gap, the careful material of sealing etc. and form.Wherein in the conducting chamber of valve ball filter bowl is housed, the port of valve body vertical cavity is as sewage draining exit, and pipe plug is housed.During use, pipeline medium is deposited on dirt or impurity on the filter bowl through filter bowl; During blowdown, close ball valve, filter bowl over against the valve body vertical cavity, is opened pipe plug under valve ball drives, can remove deposit dirt easily.

Obviously, the utlity model has rational in infrastructurely, install, blowdown is convenient, low cost and other advantages can be widely used on the industry pipe-line systems such as medicine, chemical industry, refrigeration, metallurgy.

Below in conjunction with embodiment shown in the drawings, the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structural representation that Fig. 1 closes the dress attitude.

Fig. 3 is the A-A sectional view of Fig. 2.

Referring to Fig. 1, Fig. 2, Fig. 3, Filtering ball valve is contained in the sealing seat 2 in the valve body 1 by valve body 1, valve ball 3, and valve rod 5, valve gap 4, seal ring 6, the careful material 7 of sealing and the handle 11 that is connected with valve rod 5 are formed.

Valve body 1 is a three way valve, and the port of the vertical cavity on it is as sewage draining exit, and seal ring 12 and pipe plug 13 are housed; Filter bowl 8 places in the conducting chamber 9 of valve ball 3, and is fixed on its inwall with jump ring 10; The gap that certain distance is arranged between filter bowl 8 and the conducting chamber 9 still can be unimpeded after passing through filter bowl 8 to guarantee medium.When removing dirt, close ball valve, at this moment, the filter bowl 8 in the valve ball 3 is opened pipe plug 13 just over against the port of vertical cavity, removes jump ring 10, can take out filter bowl 8 blowdowns, thereby realizes the purpose of the utility model.
