Description
Technical Field
The utility model relates to a modularization press mold structure with adjustable belongs to proportional valve technical field.
Background
The pilot valve is an important device for controlling large-flow fluid, most of the existing pilot valves separate a pilot pressure balance space by a diaphragm, the diaphragm is generally and directly arranged between a valve seat and a valve cover, and the diaphragm is clamped by the valve seat and the valve cover when the valve seat and the valve cover are arranged; although this structure is simple, it is difficult to adopt different diaphragm compression parameters for different flow rates, and it is inconvenient to customize various types of diaphragms according to different customer requirements.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an adjustable modularization press mold structure in order to overcome prior art not enough.
In order to achieve the above purpose, the utility model adopts the technical scheme that: an adjustable modular film pressing structure comprises a diaphragm, an outer ring pressing component, an outer ring supporting component, an outer ring gasket, an inner ring pressing component, an inner ring supporting component and an inner ring gasket; the outer ring pressing part and the outer ring supporting part are matched with the outer ring gasket to clamp the outer ring part of the diaphragm, and the inner ring pressing part and the inner ring supporting part are matched with the inner ring gasket to clamp the inner ring part of the diaphragm.
Preferably, the outer ring pressing part is located on the upper side of the outer ring supporting part, the inner ring pressing part is located on the upper side of the inner ring supporting part, and the outer ring gasket and the inner ring gasket are both arranged on the upper side of the diaphragm.
Preferably, the outer ring supporting component is arranged in the valve shell, and the outer ring pressing component is matched with the valve shell through a thread structure.
Preferably, the inner ring supporting component is a valve core, the inner ring pressing component is a valve rod, and the valve core is installed at the lower end of the valve rod through a thread structure.
Preferably, pilot holes are arranged on the valve rod and the valve core, and the pilot holes are used for communicating the space on the lower side of the valve core with the space on the upper side of the diaphragm.
Because of above-mentioned technical scheme's application, compared with the prior art, the utility model have the following advantage:
the utility model discloses modularization press mold structure with adjustable scheme compresses tightly the diaphragm through inner circle and outer lane two parts structure, forms modular diaphragm guide structure, and the design adjustability is very abundant, can optimize parameter and life-span, greatly reduces design and use cost.
Drawings
The technical scheme of the utility model is further explained by combining the attached drawings as follows:
fig. 1 is a schematic structural diagram of an adjustable modular film pressing structure according to the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the adjustable modular film pressing structure of the present invention comprises a diaphragm 1, an outer ring pressing component 2, an outer ring supporting component 3, an outer ring gasket 4, an inner ring pressing component 5, an inner ring supporting component 6 and an inner ring gasket 7; the outer ring pressing part 2 and the outer ring supporting part 3 are matched with an outer ring gasket 4 to clamp the outer ring part of the diaphragm 1, and the inner ring pressing part 5 and the inner ring supporting part 6 are matched with an inner ring gasket 7 to clamp the inner ring part of the diaphragm 1.
Preferably, the outer ring pressing part 2 is positioned on the upper side of the outer ring supporting part 3, the inner ring pressing part 5 is positioned on the upper side of the inner ring supporting part 6, and the outer ring gasket 4 and the inner ring gasket 7 are both arranged on the upper side of the diaphragm 1; this scheme is through upper and lower compact structure, and the cooperation gasket forms the adjustable structure of packing force of diaphragm.
The outer ring pressing part 2, the outer ring supporting part 3, the outer ring gasket 4, the inner ring pressing part 5, the inner ring supporting part 6 and the inner ring gasket 7 are all made of metal materials, and the diaphragm 1 is made of nonmetal materials, so that the diaphragm made of nonmetal materials is in intermetallic friction when being adjusted and pressed, the diaphragm is protected, and the service life of the diaphragm is greatly prolonged.
As an implementation mode, the structure of the scheme is used in a high-flow pilot valve, the outer ring supporting part 3 is arranged in the valve housing 8, and the outer ring pressing part 2 is matched with the valve housing 8 through a threaded structure; the inner ring supporting part 6 is a valve core, the inner ring pressing part 5 is a valve rod, pilot holes 9 are formed in the valve rod and the valve core, the space on the lower side of the valve core is communicated with the space on the upper side of the diaphragm 1 through the pilot holes 9, the valve core is installed at the lower end of the valve rod through a thread structure, and the tightness adjustment of the inner ring and the outer ring is achieved through the thread structure.
The large-flow valve requires large valve port area, so the differential pressure is large, the force required by the execution component is large, and the power of the execution component is large.
The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited at all; all the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
