Description
Technical field
The utility model relates to a kind of valve, specifically, particularly relates to a kind of modified model spring micro-opening safety valve.
Background technique
The roughness requirements of valve body sealing surface is higher, and general roughness will reach Ra0.2, if roughness does not reach requirement, safety valve in use just there will be leakage, and sealability can not be guaranteed.Conventional springs Low lift safety valve is integral type, namely valve seat and valve body as a whole, the sealing surface of this integrated safe valve is at body cavity, and difficulty of processing is large, and the roughness of Ra0.2 is more difficult reaches requirement, and the product reject ratio caused thus also remains high.
Summary of the invention
The utility model discloses a kind of modified model spring micro-opening safety valve, for solving, conventional springs is micro-opens the large problem of sealing surface of safety valve roughness difficulty of processing.
The utility model is achieved through the following technical solutions:
Modified model spring micro-opening safety valve, comprise valve body, valve seat, flap, pipe joint is provided with between valve seat and pipe joint nut, the sealing surface of valve seat contacts with the sealing surface of flap, be provided with the spring with spring seat between flap and spring guide sleeve, be provided with the regulating nut be connected with valve body screw thread outside spring guide sleeve, described valve body and valve seat are two individual components, valve body adopts with valve seat and is threaded, and is provided with gasket seal between described valve body and valve seat.
The inner wall thickness of described valve seat is 3-5mm.
The inner wall thickness optimum value of described valve seat is 4mm.
The outside thread model that described valve seat is offered is M24*1.5-6g.
The internal thread model that described valve body is offered is M24*1.5-6H.
Described gasket seal material is red copper.
The width of described gasket seal is 2mm-4mm, and thickness is 0.8mm-1.2mm.
The width optimum value of described gasket seal is 3mm, and thickness is 1mm.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model opens valve body of safety valve be divided into two micro-for conventional springs, is respectively valve seat and valve body, directly can processes sealing surface on valve seat, and processing easily, is guaranteed roughness, thus be ensure that the sealability that safety valve is good;
2. the utility model structure is simple, low cost of manufacture, only need change slightly on traditional spring micro-opening safety valve;
3. the utility model use value is high, and application prospect is wide.
