Abstract
The utility model relates to a liner type safety valve. The liner type safety valve comprises an inlet-side valve body, an outlet-side valve body, a valve seat, a valve flap, a valve rod, a valve cover, a spring, a sealing component and an installing component, wherein a groove is formed at the upper end of the inlet-side valve body; a groove is formed at the lower end of the outlet-side valve body; and the valve seat is fixedly installed at the groove at the upper end of the inlet-side valve body and the groove at the lower end of the outlet-side valve body. According to the utility model, anticorrosive plastic is lined inside inner cavities of the inlet-side valve body and the outlet-side valve body, so that the valve body can be made of cast iron, cast steel and other low-cost materials which are not corrosion-resistant; and the liner type safety valve has the advantages of good corrosion resistance, low cost of products and the like and is a safety protection valve applicable to working conditions with corrosive media.
Description
Technical field
The utility model relates to a kind of valve field, especially a kind of safety valve.The utility model is applicable to the Korrosionsmedium operating mode.
Background technique
At present the valve seat of safety valve is that form fix through screw thread or welding is on valve body; At the operating mode medium is under the situation of strong corrosive mediums such as hydrochloric acid, sulfuric acid, and whole valve material all is that nickel-base alloy, super stainless steel or the integral body selecting to be able to bear strong corrosion are selected materials such as teflon for use.The major defect of this structure is: body cavity can't the anti-corrosion plastics of liner, are directed at whole valve material and all select the high material of corrosion resistance for use, and cost is high.
Summary of the invention
The purpose of the utility model is the shortcoming that exists to existing technology, and a kind of good corrosion resistance, lined safety valve that cost is low are provided.
The utility model is realized through following scheme:
This lined safety valve mainly comprises suction side valve body, outlet side valve body, valve seat, flap, valve rod, valve gap, spring, Sealing and assembling set; Suction side valve body upper end is provided with groove; The outlet side valve body lower end is provided with groove; Valve seat is fixedly mounted on suction side valve body upper end groove and outlet side valve body lower end groove, mainly is to be lined with anti-corrosion plastics at suction side valve body and outlet side body cavity.
The utility model has the advantages that suction side valve body and outlet side body cavity are lined with anti-corrosion plastics, valve body can be selected lower cost materials such as not corrosion resistant cast iron, cast steel, and its corrosion resistant performance is good, product cost is low.
