Embodiment Construction

[0010] Such as figure 1 The forged steel Y-type globe valve shown includes a valve body 3, a valve seat 8, a valve cover 15, a valve disc 9, a valve stem 10, a transmission mechanism, seals and mounting parts, and a filter is provided in the outlet channel of the valve body 4. The filter device is composed of a filter chamber 5 communicated with the outlet channel, a filter screen 6 installed in the filter chamber 5 and a filter chamber end cover 2. When the disc 9 is opened, the medium enters the filter screen 6 from the inlet channel of the valve body 3 through the valve seat 8 to be filtered, and then flows out from the outlet channel of the valve body 3, so that the outlet medium is purified and filtered. The filter screen 6 is made into a cylindrical shape by wire mesh, and a filter element 7 is set inside the wire mesh. The filter element 7 is a porous stainless steel cylinder with the same shape as the wire mesh, which is installed close to the wire mesh to increase the...

Abstract

The invention relates to the technical field of valves, in particular to a forged steel Y-shaped valve. The forged steel Y-shaped valve comprises a valve body (3), a valve seat (8), a valve cover (15), a valve flap (9), a valve rod (10), a transmission mechanism, a sealing piece and a mounting piece. The valve is characterized in that an outlet channel of the valve body (3) is provided with a filter device consisting of a filter room (5) communicated with the outlet channel, a filter net (6) arranged in the filter room (5) and a filter room end cover (2) inside. Compared with prior art, the valve has the advantages that the outlet channel of the valve body is provided with the filter device inside which allows a medium to pass through the valve seat and then the filter device, so that the valve can filter and purify the medium.

Description

[technical field] [0001] The invention relates to the technical field of valves, in particular to a forged steel Y-shaped valve. [Background technique] [0002] Globe valves are widely used in pipeline control or switch valves in petroleum, chemical, metallurgy, electric power, water treatment and other production fields. Filtration and purification, therefore, for working conditions that require high purity of the medium, another filter needs to be installed on the pipeline. [Content of the invention] [0003] The purpose of the present invention is to provide a forged steel Y-type stop valve with the function of filtering and purifying the medium in view of the shortcomings of the prior art. [0004] The technical solution for realizing the purpose of the present invention includes valve body, valve seat, valve cover, valve disc, valve stem, transmission mechanism, seal and mounting parts, mainly a filter device is arranged in the outlet channel of the valve body, and t...
