Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, so that the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, the type, quantity and proportion of the components in actual implementation can be changed freely, and the layout of the components can be more complicated.
The method, the system and the device for calculating the ship pipe system fastener are used for accurately calculating the specification and the number of the fasteners required by the installation of pipelines and valves.
As shown in fig. 1a, in one embodiment, the method for calculating a ship pipe system fastener of the present invention comprises the following steps:
and step S11, acquiring the system information of the gasket according to the three-dimensional model of the gasket.
In particular, the three-dimensional model of the shim is obtained based on existing information. For example, the pre-acquired piping model structure tree acquires a three-dimensional model of all shims under the structure tree. The three-dimensional model of the gasket is a three-dimensional model comprising a gasket structure and a flange or valve member structure connected with the gasket structure. The three-dimensional model contains much information, including: and system information, wherein the system information refers to information of a system to which the gasket belongs, and different systems correspond to fasteners with different configuration information.
And step S12, acquiring system fastener configuration information according to the system information.
Specifically, the configuration information of the fastener corresponding to the system may be obtained according to the system information. I.e., different systems correspond to fasteners of different configuration information. The system fastener configuration information includes: name, material, standard number and weight information of the gasket; name, material, standard number and weight information of the bolt; name, material, standard number and weight information of the nut. The system information is acquired. Different systems correspond to different configurations of fasteners, which are preset.
And step S13, acquiring the connection form of the flange or the valve member connected with the gasket according to the three-dimensional model of the gasket.
Specifically, acquiring space coordinate values of connection points of all gasket, flange, valve member and valve accessory models related to the gasket according to the three-dimensional model of the gasket, and reading screw hole attributes of the flange, the valve member and the valve accessory, wherein the screw hole attributes comprise screw hole specifications and screw hole quantity, and the screw hole specifications can reflect the outer diameter of a screw hole; the length of the bolt penetrating through the part model with the screw hole is the connection length; an identifier representing the form of the connection is also included. After reading the part connection point coordinate values and the screw hole attributes of each part, the information is written into a database. It should be noted that the screw hole attribute should be well defined when modeling the flange or valve member model, and belongs to the known attribute.
Specifically, the method further comprises the steps of obtaining space coordinates of the three-dimensional model of the gasket, and inquiring a flange or a valve connected with the gasket within a preset distance range in a database based on the space coordinates. The shim and its associated part model are sometimes not at the same stage, the associated part is typically a flange or valve member, and when calculating the fastener, only parts such as a gasket model, a flange or a valve and the like in the current stage model structure tree can be matched with connected parts in other stage models directly according to the space coordinates of the current gasket model, therefore, the connection parts need to be matched by a method of inquiring the database, the information of the parts connected with the gasket needs to be matched by the inquiry database according to the coordinate value of the connection point of the gasket, because the parts to which the shim is attached are sometimes not fully contiguous when designed, there may be a gap of less than 3mm in the middle, therefore, when the coordinates are matched, the distance range is set to be within 3mm, the connecting part is calculated, the information of the connecting part is matched, if the coordinates of the connection points at the two ends of the gasket are matched with the connection part at one end, the connection part at the other end is the same as the connection part at the other end by default. According to the connection part information of the gasket, what part is connected with the gasket can be obtained, and the connection form can be obtained.
Specifically, the gasket model is arranged at the position where the pipeline is fastened by the bolt, and the bolt and nut data and the gasket data are reflected in the same data list, so that the number and the specification of the bolt and nut are calculated according to the gasket model.
Specifically, the connection form includes: non-butt-clamped and butt-clamped. And acquiring the connection form based on the identification of the connection form. A butt-clamped version and a non-butt-clamped version. As shown in fig. 1b, the non-butt clamp type is a non-butt clamp type, in which two ends of a gasket 101 are connected to a common flange 102 or a common valve member, and all bolts 103 pass through screw holes and nuts 104. As shown in fig. 1c, in a butt-clamp fashion. The butt-clamping mode is generally used for fastening a butt-clamping valve 105, two gaskets 101 are connected to two ends of the butt-clamping valve, the two gaskets are connected with the two flanges 102, long bolts can penetrate through the two flanges, the two gaskets and the middle butt-clamping valve, short bolts 106 cannot penetrate through the two flanges, and only the flange screw holes penetrate through the middle of the butt-clamping valve screw holes. The number of fasteners counted and the bolt length are not the same in both forms.
And step S14, acquiring the screw hole attribute of the flange or the valve member according to the connection form.
Specifically, the screw hole attributes include screw hole specifications and screw hole quantity, and the screw hole specifications include screw hole outer diameters. Based on the screw hole attributes, the attributes and number of nuts and bolts that are paired with the screw hole attributes can be known. The properties of the bolt include the bolt outer diameter and the nut properties include the nut outer diameter, which are all derived from the screw hole properties, since the screw hole outer diameter, the bolt outer diameter and the nut outer diameter are all correspondingly paired. The screw hole specification further includes: the valve body screw specification, the length of the bolt penetrating through the valve member, the gasket thickness flange screw specification, the length of the bolt penetrating through the flange, and the nut length. Screw quantity includes: the number of valve body screw holes and the number of flange screw holes.
Step S15, when the connection form is a non-butt clamp form, judging whether extra thickness needs to be added, and when the extra thickness does not need to be added, calculating the length of the bolt based on a first non-butt clamp preset fastener calculation formula according to the property of the screw hole so as to obtain the number and specification information of the fasteners; when extra thickness needs to be added, calculating the length of the bolt based on a second non-butt clamp preset fastener calculation formula according to the screw hole attribute and the extra thickness, so as to obtain the number and specification information of the fasteners; when the connection form is a butt clamp form, judging whether extra thickness needs to be added, and when the extra thickness does not need to be added, calculating to obtain the length of the bolt according to the property of the screw hole and based on a first butt clamp preset fastener calculation formula, so as to obtain the number and specification information of the fasteners; when extra thickness needs to be added, the length of the bolt is calculated and obtained based on a calculation formula of the second pair of clamp preset fasteners according to the screw hole attribute and the extra thickness, and therefore the number and specification information of the fasteners are obtained. Wherein, fastener quantity and specification information include: the number of the gaskets (generally one), the number and specification of the nuts (the number of the nuts is determined by the number of the screw holes, the diameter specification of the nuts corresponds to the diameter specification of the screw holes), and the number and specification of the bolts (the number of the bolts is determined by the number of the screw holes, and the diameter specification of the bolts corresponds to the diameter specification of the screw holes).
Specifically, when no extra thickness needs to be added and when the connection form is a non-butt clamp form, the first non-butt clamp pre-set fastener calculation formula is as follows: the bolt length is equal to the thickness of the penetrating flange multiplied by 2+ the thickness of the gasket + the length of the nut + the pitch of the first preset multiple. And the number of the nuts is the same as that of the screw holes (the number of the valve body screw holes or the number of the flange screw holes), and the number of the bolts is also the same as that of the screw holes. The first preset multiple is 2-3 times. The non-butt clamp is typically a two-piece flange clamp with a gasket, or a valve member and a flange with a gasket therebetween. In the embodiment, the sizes and the quantities of the screw holes of the flange part models connected with the two ends of the gasket are consistent. For example, the specification of a flange screw hole is M12, the number of the screw holes is 4, the thickness of a bolt penetrating through the flange is 16mm, namely, the connection length is 16mm, the thickness of a gasket is 3mm, the specification of the screw hole corresponds to the thread pitch and the nut length and is provided with a nut specification configuration file, the thread pitch of an M12 thread can be obtained by reading the nut specification configuration file according to the nut specification M12, the nut length is 10.8mm, the bolt length can be calculated according to the parameters, and the bolt penetrating through the nut usually keeps 2-3 thread lengths, so the calculated bolt length is: thickness X2+ gasket thickness + nut length +2-3 times the pitch of the screw thread, so bolt length L16X 2+3+10.8+ 1.75X 2.5 is 50.175mm, bolt length generally takes 5mm as the gear, the part less than 5mm needs to be increased to 5mm gear, so bolt length should be 55mm, the number of screw holes is 4, so the fastener that this gasket is correlated with has 1 gasket, 4 nuts of M12 (the nut quantity is determined by the screw hole quantity, the nut diameter specification corresponds to the screw hole diameter specification), 4 bolts of M12X55 (the bolt quantity is determined by the screw hole quantity, the bolt diameter specification is also determined by the screw hole diameter specification), thereby obtain the fastener quantity and specification information. Therefore, the acquisition of the number and specification information of the fasteners under the condition that the connection mode of the flanges or the valves connected by the gaskets is a non-butt-clamping mode is realized.
Specifically, when no additional thickness needs to be added and when the connection form is a butt-clamp form, the first butt-clamp preset fastener calculation formula is: the length of the long bolt is equal to the length of the bolt penetrating through the valve, the length of the bolt penetrating through the flange is equal to 2+ the thickness of the gasket is equal to 2+ the length of the nut, and the distance between the first preset times of threads + the reserved distance. The length of the short bolt is equal to the length of the bolt penetrating through the valve element, namely 0.5+ the length of the bolt penetrating through the flange + the thickness of the gasket-a reserved distance. For example, the specification of screw holes and the number of screw holes are obtained based on the property of the screw holes, the counter clamp valve is set to be a butterfly valve, the specification of the screw holes is M16, the number of the screw holes of the valve body is 4, the length of bolts penetrating through the counter clamp valve is 56mm, the thicknesses of gaskets at two ends are respectively 3mm, the specification of screw holes of flanges at two ends is M16, the number of the screw holes is 8, and the length of the bolts penetrating through the flanges is 20 mm. According to the screw hole information, the fastening combination form has long bolts and short bolts, the short bolts penetrate through the flange screw holes and penetrate through the valve member screw holes in half, the valve member screw holes are used for the short bolts, the number of the long bolts and the number of the short bolts are determined according to the difference value between the number of the paired valve screw holes and the number of the flange screw holes, the number of the long bolts is obtained by subtracting the number of the valve member screw holes from the number of the flange screw holes, namely n1 is 8-4 and 4, the number of the short bolts is obtained by multiplying the number of the valve member screw holes by 2, namely n2 is 4 and 2 and 8, and the length of the long bolts is calculated as: the length of the bolt penetrating through the valve piece + the length of the bolt penetrating through the flange X2+ the thickness of the gasket X2+ the length of the nut +2-3 times the pitch + the reserved distance, the pitch of the M16 threads is 2mm by reading the nut specification configuration file according to the nut specification M16, the length of the nut is 14.8mm, so the length of the long bolt L1 is 56+20 + 2+3+ 2+14.8+ 2+ 2.5+5mm is 126.8mm, the length of the long bolt is 130mm, because only bolts with lengths of 125mm and 130mm are screwed in the flange screw hole, the short bolt only penetrates through half of the valve screw hole, and the length of the short bolt needs to be withdrawn by 5mm (the reserved distance) in order to prevent the short bolts at two ends of the valve screw hole from being abutted, the nut is not needed, so the short bolt has the calculated length as follows: the length of the bolt penetrating through the valve is 0.5+ the length of the bolt penetrating through the flange is + the thickness of the gasket-a reserved distance, so that the length of the short bolt L2 is 56 × 0.5+20+30-5mm is 47mm, the length is 50mm, and only bolts with the length of 45mm or 50mm are used, so that the connecting type fastener comprises 2 gaskets (two gaskets in a non-butt-clamping mode), 4 long bolts with the specification of M16X125 (the number of the long bolts is the number of the flange screw holes minus the number of the valve screw holes), 4 nuts with the specification of M16 and 8 short bolts with the specification of M16X50 (the number of the short bolts is the number of the valve screw holes multiplied by 2). Therefore, the connection mode of the flange or the valve member connected by the gasket is the acquisition of the number and specification information of the fasteners in the clamping mode. It should be noted that, when the number of screw holes of the pinch valve is the same as the number of screw holes of the flange connected thereto, the above calculation method is also applicable, and when the number of screw holes of the pinch valve is 0, all the screw holes are through-type long bolts, the above calculation method is also applicable.
Specifically, it also includes the specific range that the judgment of the bolt length falls into, and the existing bolts are generally manufactured according to the classification of the length of 5mm, for example, 15mm bolts, 20mm bolts, 25mm bolts, etc., so that after the bolt length is calculated, it is necessary to judge the actual bolt length according to the calculated bolt length, for example, the calculated bolt length is 21mm, then the actual bolt length is 25mm,
in particular, the additional thickness comprises: a double-headed nut thickness, a flat washer thickness, and/or a jumper thickness. When extra thickness needs to be added and the connection form is a non-butt clamp form, the second non-butt clamp preset fastener calculation formula is as follows: the bolt length is equal to the length of the bolt penetrating through the valve piece + the length of the bolt penetrating through the flange + 2+ the thickness of the gasket + the length of the nut + the pitch of the first preset multiple of the screw teeth + the extra thickness. When extra thickness needs to be added and the connection form is a butt clamp form, the second butt clamp preset fastener calculation formula is as follows: the length of the long bolt is equal to the length of the bolt penetrating through the valve, the length of the bolt penetrating through the flange is equal to 2, the thickness of the gasket is equal to 2, the length of the nut is equal to the length of the first preset multiple of the pitch of the threads, the reserved distance and the extra thickness; the length of the short bolt is equal to the length of the bolt penetrating through the valve element, namely 0.5+ the length of the bolt penetrating through the flange, the thickness of the gasket, the reserved distance and the extra thickness. Triggering the pipeline fastener through a program interaction interface to calculate, wherein the fastener calculates special conditions based on the two fastening combination forms in addition to the two fastening combination forms, the special conditions can be selected and confirmed through the calculation interface, the special conditions are that extra thickness needs to be added, and the thickness of the double-head nut is increased: the double-end stud type is that nuts are arranged at two ends of a bolt, 2 times of the length of the nuts need to be considered when the length of the bolt is calculated, the two ends exceed the distance of the threads of the nuts by 2-3, and the number of the nuts is doubled compared with that of the ordinary type; increasing the thickness of the flat gasket: the flat washer adding mode is that one bolt in one group of fasteners needs to be matched with two flat washers, and compared with the common mode, the quantity of the two flat washers is increased, wherein the thickness of the two flat washers needs to be considered in the calculation of the length of one bolt, and the thickness of the flat washers is also obtained on the inner surface and the outer surface of the nut specification configuration; thickness of the jumper: the jumper is added, namely one bolt in a group of fasteners needs to be matched with one jumper, compared with the common type, the jumper is added by one jumper amount, the length of one bolt needs to consider the thickness of one jumper, and the thickness and the specification of the jumper are obtained on the front surface and the back surface of the nut. Through the combination of the interactive interface and the configuration table, more calculations of the fastener accessories can be expanded, and the fastener accessories are similar to flat washers and jumpers. The calculated fastener data are written into a database, and the data can be conveniently checked at any time. Of course, the thickness of the stud nut, the thickness of the flat washer and/or the thickness of the jumper may be selected from only one or any number of the additional thicknesses, all according to specific requirements.
It should be noted that the vessel piping fastener calculation method provided by the embodiment can be applied to not only the calculation of the vessel piping fastener, but also the calculation of the piping fastener of an aircraft, a train or an automobile.
