Description
Technical field
This utility model relates to a kind of relief valve, particularly relates to a kind of ripple be applicable to mechanical industry pipe-line system
Pipe fall lift type spring safety valve.
Background technology
At present, spring loaded safety valve is that one is applied on the pressurized equipment such as boiler, pressure vessel as overpressure protection dress
Put, when container or pipeline internal medium overpressure, act on active force on flap more than spring force or weight power after, flap
Automatically rise, valve opening, define a pressure release passage, high voltage relief is fallen.Treat that container or manifold pressure fall below
Blowdown pressure of safety valve, flap automatically falls on valve seat, valve closing, stops gas discharge, container or pipeline to recover normal work
Make.
Corrugated tube in corrugated tube relief valve can eliminate the back-pressure surges impact on valve performance, moreover it is possible to protection spring and
Other internals are from the corrosion of medium.Existing ripple relief valve corrugated tube waveform uses S-shaped, and some small-bore relief valve needs
Want the corrugated tube that internal diameter is little, and the corrugated pipe forming difficulty that internal diameter is little, so common S type corrugated tube is not suitable for some bore
The bellows springs formula relief valve little, nominal pressure is little, structural volume is less and valve stroke is little.Therefore research and development one is suitable for little
The corrugated tube that the spring loaded safety valve of bore is suitable for, is a problem in the urgent need to address.
Summary of the invention
The purpose of this utility model is to provide a kind of corrugated tube fall lift type spring safety valve, and this utility model is rational in infrastructure,
He meets the requirement of the bellows springs formula relief valve that pressure is little, structural volume is less and valve stroke is little, and it has safety
Energy-conservation, good airproof performance, avoid serious accident to occur, raising system is run safety and is had the feature of dual-seal simultaneously.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
Corrugated tube fall lift type spring safety valve, it includes valve body, valve seat and bellows component, wherein bellows component be by
Flap, corrugated tube, fairlead are constituted, and corrugated tube is to be welded, by blocks of ripple section of jurisdiction, the double S type structures constituted.
The wave number of above-mentioned corrugated tube is 25, and thickness is 0.1mm.
Above-mentioned corrugated tube upper and lower side is arranged on corrugated header, the corrugated header of upper and lower side respectively with fairlead and flap
Being welded to connect, molten a width of 0.2-0.4mm of weld seam, fusion penetration is 0.1-0.2mm.
Owing to using technique scheme so that this utility model has the advantage that and effect:
Through verification experimental verification, this utility model uses corrugated tube double S type design structure, and the sealing property of valve is more preferable.With
Prior art is compared, and he meets wanting of the bellows springs formula relief valve that pressure is little, structural volume is less and valve stroke is little
Ask, and there is advanced design, rational in infrastructure, energy-saving safe, raising service life, meet and use requirements, good airproof performance, avoid evil
Sexual behavior thus occur, reduce pressure loss in piping, improve system run all right there is the advantage of dual-seal simultaneously, be suitable for application
In the industries such as electric power, metallurgy, oil, chemical industry, applied range.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model corrugated tube fall lift type spring safety valve.
Fig. 2 is the structural representation of bellows component in Fig. 1.
In figure, 1, valve body, 2, valve seat, 3, bellows component, 4, flap, 5, corrugated tube, 6, fairlead, 7, corrugated header.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.Following example are only tool of the present utility model
Body embodiment, but design concept of the present utility model is not limited thereto, all utilizes this design that this utility model is carried out non-solid
The change of matter, all should belong to the behavior invading this utility model protection domain.
As depicted in figs. 1 and 2, this utility model corrugated tube fall lift type spring safety valve, it includes valve body 1, valve seat 2 and ripple
Stricture of vagina pipe assembly 3, wherein bellows component 3 is to be made up of flap 4, corrugated tube 5, fairlead 6, and corrugated tube 5 is by blocks of ripple
Double S type structures that section of jurisdiction welding is constituted.The optimal wave number of corrugated tube 5 is 25, and thickness is 0.1mm, and this cannot be used for limiting this reality
With in novel protection valve.
Corrugated tube 5 upper and lower side is arranged on corrugated header 7, and the corrugated header 7 of upper and lower side welds with fairlead 6 and flap 4
Connecting, molten a width of 0.2-0.4mm of weld seam, fusion penetration is 0.1-0.2mm.
Design principle of the present utility model is as follows:
Corrugated tube 5 is the double S types design being made up of the welding of blocks of ripple section of jurisdiction, carries out at Vacuum Heat after bellows-welding
Reason, decrement is more than 6mm.Have employed three Dimensional CAD Design technology, set up valve body, corrugated tube, the mechanical model of flap part, and
Above part is carried out finite element analysis and calculating, draws best design parameter.
Through verification experimental verification, the sealing property of the valve of corrugated tube double S type design is used to reach better seal effect.This
Illustrate double S-shaped corrugated tube for the design structure of bellows springs formula relief valve be reasonably, performance be reliable, be entirely capable of full
Foot uses requirement.
