Abstract
The invention provides a metallic diaphragm for an instrument membrane valve. The metallic diaphragm is widely applied to the instrument membrane valve and is characterized in that according to the pressure, the temperature and the medium requirement of the membrane valve, a thin film which is 0.02-0.2mm thick is made by adopting a proper metallic material, and then, according to the flow (drift diameter) of the valve, the single-layer or equal-thickness multi-layer S-shaped, S circular arc-shaped, U-shaped or circular arc-shaped metallic diaphragm is processed by selecting proper geometrical shapes. The metallic diaphragm for the instrument membrane valve is a key component in the high-temperature and high-pressure toxic, flammable and explosive and radiative membrane valve which is possibly harmful to safety, environments or health and does not leak definitely.
Description
Technical field
The present invention relates to the design and the manufacturing of valve, be widely used in the industrial pipeline, the liquid in the instrumentation pipelines such as all kinds of flows in particularly controlling automatically, differential pressure, pressure, liquid level or the keying and the control gear of gas.
Background technique
At present, the diaphragm of the instrument membrane valve of extensive use mostly is to be processed by nonmetallic material such as rubber, teflon, and its working pressure is general≤1MPa, operating temperature is general≤and 180 ℃, but can't satisfy for Intermediate High Pressure and high temperature media.The present invention adapt to high temperature, high pressure, poisonous, inflammable, explosive, have radioactivity etc. never to allow the occasion that leaks outside to what safety, environment and healthy worked the mischief.
Summary of the invention
The object of the present invention is to provide a kind of high temperature, high pressure, poisonous, inflammable and explosive and have radioactivity etc. to cut off the key member that allows in the membrane valve that leaks outside of being applicable to what safety, environment or healthy worked the mischief; Process the metallic material that is fit on the diaphragm of definite shape with high temperature high voltage resistant; Be used for membrane valve, make medium and valve upper isolation, shielding.
Technological scheme of the present invention is:
1, laminate having good yield strength, antifatigue, radioresistance or high temperature resistant, anti-oxidant, corrosion resistant metallic material, its thickness is that 0.02～0.2mm does not wait.
2, geometrical shape has: S type, S circular arc type, U type and circular arc type are fit to select for use under the conditions such as various flows (latus rectum), pressure, temperature.
3, the thin plate of processing just being carried out shear forming processing according to the latus rectum size of valve and pressure, can be individual layer, also can be multilayer.According to big or small thickness in monolayer and the physical dimension of confirming diaphragm of the flow (latus rectum) of valve, flow (latus rectum) is big more, and it is thin more that the thickness in monolayer of diaphragm is then selected, and the physical dimension at each position is also just big more; Confirm the number of plies of diaphragm according to the thickness in monolayer of the pressure of valve height and diaphragm, pressure is high more, and the number of plies of equal thickness is just many more.During shaping operation, the diaphragm of equal thickness multilayer machines according to the number of plies of the confirming disposal molding that stacks up.
4, should keep the integrity of multilayer diaphragm after the shaping operation, can not misplace, the edge should be neat, and no burr keeps clean.
5, heat-treat, heat-treat, improve the due performance of metallic material according to the characteristic of different metal material.
Advantage of the present invention and beneficial effect:
1, the present invention adopts the metallic material manufacturing adapt, is applicable to high temperature, high pressure, poisonous, inflammable and explosive and have radioactivity etc. to cut off the key member that allows in the membrane valve that leaks outside to what safety, environment or healthy worked the mischief.
2, select the different metallic material according to different media, pressure, temperature requirement, comparatively ideal high-temperature yield strength, antifatigue, radioresistance, anti-oxidant, decay resistance are arranged.
3, geometrical shape has four kinds of S type, S circular arc type, U type and circular arc types, is suitable for selecting for use under the conditions such as various flows (latus rectum), pressure, temperature, medium.
Description of drawings
Figure one, be S type metal diaphragm.
Figure two, be the circular arc type metal diaphragm.
Figure three, be S circular arc type metal diaphragm.
Figure four, be U type metal diaphragm.
Figure five, metal diaphragm position in membrane valve.
Among the figure: 1, the uniform thickness number of plies of the external diameter n of handwheel 2, valve rod 3, metal diaphragm 4, valve gap 5, spring 6, spool 7, valve body D, diaphragm, diaphragm.
Embodiment
Below in conjunction with accompanying drawing and enforcement case the present invention is further specified.
The S type diaphragm of figure one is the stack up diaphragm of machine shaping of individual layer or equal thickness multilayer, and its circumference is parallel parallel to the middle center of circle to S type curve transition, is mainly used in the bigger membrane valve of flow (latus rectum).
The circular arc type diaphragm of figure two is processed into the diaphragm of circular arc type for individual layer or equal thickness multilayer stack up, its circumference is parallel carry out the transition in the middle of circular arc, be mainly used in the little membrane valve of flow (latus rectum).
The S circular arc type diaphragm of figure three is processed into the diaphragm of S circular arc type for individual layer or equal thickness multilayer stack up, and its circumference is parallel to S type curve transition to middle circular arc, is mainly used in the big membrane valve of flow (latus rectum).
The U type diaphragm of figure four is processed into the diaphragm of U type for individual layer or equal thickness multilayer stack up, and its circumference is parallel parallel to the middle center of circle to U type curve transition, is mainly used in the medium membrane valve of flow (latus rectum).
Figure five is routine instrument membrane valve structural drawing, illustrates the position and the effect at metal diaphragm place.Metal diaphragm 3 is the top that an elastic element places valve body 7, drives valve rod 2 rotations through handwheel 1 and moves up and down, and promotes spool 6 through metal diaphragm 3 and carries out closing of valve; When valve rod 2 rose, spring 5 resetted and promotes spool 6 and rises the implementation valve opening synchronously; Metal diaphragm 3 is fixed by valve gap 4 and valve body 7 tops and is sealed, the complete shield gasket of medium in the inside of valve body 7, in the valve opening and closing process; Metal diaphragm 3 is an elastic element; Be again a safety curtain, should bear next ducted HTHP, bear various poisonous, inflammable and explosive and the erosion of media such as radioactivity arranged again; Also will have good yield strength, antifatigue, radioresistance and high temperature resistant, anti-oxidant, corrosion resistant ability, be vital parts.
