Fig. 1 to 6 schematically disclose a gate valve provided in this embodiment, which includes a valve body 1 and a valve plate 2 movably disposed on the valve body 1, where the valve plate 2 moves to different positions to realize opening and closing of a valve port. Specifically, the gate valve in the embodiment of the disclosure is a vacuum gate valve, and a driving structure is mounted at the upper end part of the valve body 1 of the gate valve, and the driving structure can be divided into a cylinder driving mode, an oil cylinder driving mode, a motor driving mode and the like according to the use working conditions. The driving structure in this embodiment is driven by a cylinder. Referring to fig. 4 and 5, the valve body 1 of the gate valve at least comprises an upper valve body and a lower valve body which are mutually butted, a valve port is reserved at the butted position of the upper valve body and the lower valve body, and a pipeline and the like are clamped at the valve port. Further, an accommodation space is formed at the intermediate position of the upper valve body and the lower valve body along the movement direction of the valve plate 2, and the valve plate 2 is disposed in the accommodation space and is reciprocally movable up and down in the accommodation space.

It will be appreciated that in the embodiment of the present disclosure, the movement form of the valve plate 2 in the valve body 1 is a linear reciprocating movement, and as a variant embodiment, the valve plate 2 may also reciprocate or rotate in the valve body 1. Obviously, based on the different movement forms of the valve plates 2, the form of the driving structure and the form of the transmission structure between the valve plates 2 need to be changed correspondingly, for example, when the valve plates 2 adopt a swinging form, the transmission structure can adopt the forms of a hinging seat and a hinging rod.
It will be appreciated that the basic structural form of the gate valve of the present disclosure may also be other types of valve structures, such as common ball valve structures, and the like.
For a clearer understanding of the present disclosure, explanation is made below of at least one design background of a gate valve in an embodiment of the present disclosure:
The gate valve of the present disclosure is used on a beam transport line in accelerator technology. The beam current measurement on the beam line is realized by adopting a Faraday cage, the basic principle is that the beam current reaches the metal receiving body to generate current, the intensity of the beam current is judged according to the magnitude of the current, and the Faraday cage is generally arranged on the beam current transmission line at intervals to measure the beam current, so that the accuracy of beam current transmission is ensured, and the Faraday cage is also used as the basis for selecting parameters of a beam adjustment component on the beam line. The vacuum between each section of pipeline is sealed by using a gate valve on the beam transmission line, and the gate valve is generally arranged in front of and behind the key parts or at intervals. The common characteristics of the two are that the sealing valve plate of the gate valve and the Faraday cylinder measuring body are both oriented to the beam direction; in the beam adjustment and measurement processes, the Faraday cage measuring body and the gate valve plate are inserted into a beam pipeline, and the center of the Faraday cage measuring body and the center of the gate valve plate are overlapped with the center of the pipeline; when the beam passes, the Faraday cylinder measuring body and the gate valve plate are lifted, so that the smooth flow path of the beam is ensured. In some special beam segments, only a gate valve can be installed to isolate vacuum, and no space is provided for a Faraday cage.
Based at least on the above design background, the gate valve in the embodiments of the present disclosure further includes: a measuring body 3, which is arranged on the valve plate 2, and the measuring body 3 is suitable for being arranged facing the beam current to detect the intensity change of the beam current when the gate valve is in an operating state; and the insulator 4 is arranged on the valve plate 2 and is used for separating the measuring body 3 and the valve plate 2, so that the beam intensity is measured.
Referring to fig. 2, a measuring body 3 in an embodiment of the present disclosure includes: a receiver 31 disposed on the valve plate 2 for receiving the beam and generating a signal change; and a guide body 32 connected to the receptor 31 for guiding the signal change to an external beam intensity detection mechanism. It should be noted that, based on the detection principle, after the receptor 31 receives the beam, a current is generated on the receptor 31, and the intensity of the beam is determined according to the current change, and in the embodiment of the present disclosure, the receptor 31 is made of a metal material, which has conductivity, preferably, the receptor 31 is made of metal copper. The copper material has low cost and mature processing technology.
It is understood that the structural form of the receiving body 31 is not limited, and may be a sheet, a block, a ball, a protrusion, a cylinder, etc., and for convenience of description, the receiving body 31 in the embodiment of the present disclosure is a metal copper sheet.
It will be appreciated that there may be a plurality of locations where the receptor 31 is mounted on the valve plate 2, such as a snug fit on the end face of the valve plate 2; for another example, the outer surface of the valve plate 2 is coated; for another example, a gap is reserved between the end face of the valve plate 2 and the end face of the valve plate 2; for example, it is fitted to an end surface of the valve plate 2. When the valve plate 2 closes the pipeline at the valve port, the receptor 31 on the valve plate 2 can be ensured to receive the beam.
It will be appreciated that there may be a variety of contoured shapes for the receiving body 31, such as square, circular, triangular, etc. In order to ensure good sealing performance, the metal copper sheet in the embodiment of the disclosure is round, square and other structures with sharp corners are easy to damage subsequent insulating structures.
The receiver 31 is mounted on the valve plate 2 in various ways, such as by gluing, based on the above-mentioned mounting positions. As shown in fig. 2 and 3, in the embodiment of the present disclosure, the end surface of the valve plate 2 is provided with a groove 22, and preferably, the shape of the groove 22 is consistent with the shape of the receptor 31, such as the groove 22 is machined into a circular shape.
It should be noted that, the external dimension of the receptor 31 needs to be smaller than the dimension of the groove 22, for example, when the shapes of the groove 22 and the receptor 31 are circular, it is necessary to ensure that the diameter of the receptor 31 is smaller than the diameter of the inner groove of the groove 22, so as to prevent the receptor 31 from adhering to the inner groove wall of the groove 22, and thus the current generated by the receptor 31 is guided to the valve plate 2.
It should be noted that, when the receiving body 31 is mounted on the groove 22, preferably, the receiving body 31 is integrally embedded in the groove 22, and the depth of the groove 22 is ensured to be larger than the thickness of the receiving body 31 during design. As a variant embodiment, the receptor 31 may be only partially embedded in the groove 22, and the end surface of the valve plate 2 is partially protruded, so that when the service life of the receptor 31 is limited or damaged, the receptor 31 is conveniently detached from the valve plate 2 to replace the receptor 31.
Based on the above, one dimensional form of the valve plate 2 as disclosed in fig. 2 is: a circular groove having a diameter of 22mm and a depth of 1mm was removed at the center of the end face of the valve plate 2. The adopted metal copper sheet has the size of 20mm in diameter and 0.5mm in thickness, and the fixing mode is gluing.
The center of the receptor 31 is arranged coincident with the center of the valve plate 2 in the embodiment of the present disclosure. When the gate valve is basically designed, in order to ensure the plugging effect on a pipeline, the center of the valve plate 2 is overlapped with the center of a pipeline, wherein the center of the pipeline is a center point of a graph on the cross section of the pipeline, and the center of the valve plate 2 is the center of the outline shape of the end face of the valve plate 2. The center of the receptor 31 is the center of the contour shape of the end face of the receptor 31 facing the beam. When the beam is transmitted in the beam pipe, the beam is influenced by the wall resistance of the inner surface of the pipe, so that the intensity of the beam near the wall resistance is unstable. The center of the receptor 31 is coincident with the center of the valve plate 2, namely, the center of the receptor 31 is coincident with the center of the beam pipeline, so that the receptor 31 can better receive the beam at the center of the pipeline, and the detection precision is ensured.
In order to prevent the current generated by the susceptor 31 by the beam from being conducted to the valve plate 2 in the embodiment of the present disclosure, an insulator 4 is provided between the valve plate 2 and the susceptor 31. Referring to fig. 2, the insulator 4 includes: a first insulator 41 disposed between the receptor 31 and the recess 22; specifically, the first insulator 41 covers at least the groove bottom and the groove wall of the groove 22, so as to cover the end surface of the butt-joint receptor 31 facing the groove bottom and the circumferential surface in the thickness direction, and effectively prevent the butt-joint receptor 31 from directly contacting the valve plate 2.
Further, in the embodiment of the present disclosure, the first insulator 41 is configured as an insulating film, and a vacuum sealant is disposed between the insulating film and the groove 22, so that the insulating film has good ductility and insulation, and the first insulator 41 is more conveniently laid in the groove 22 when the insulation effect is ensured. The use of the vacuum sealer can further enhance the insulating effect and effectively fix the insulating film on the groove 22.
In the embodiment of the present disclosure, when the receptor 31 is mounted in the groove 22, firstly, a vacuum sealant is coated on the bottom and the wall of the groove 22, the first insulator 41 is pasted, the vacuum sealant is coated on the exposed end surface of the first insulator 41 again, and the receptor 31 is pasted, so that the assembly between the receptor 31 and the valve plate 2 is completed.
With continued reference to fig. 2, the guide 32 in the embodiments of the present disclosure is configured as a metal lead, and the material is copper, as well as other conductive materials. Further, the main body portion of the metal lead is arranged along the movement direction of the valve plate 2 in the embodiment of the present disclosure. As described above, the valve plate 2 is linearly reciprocated by the driving structure, the metal lead wire is connected to the receiver 31 on the valve plate 2, and there is a process of contraction and expansion of the metal lead wire as the valve plate 2 moves. In order to prevent the metal lead from interfering with the structure inside the valve body 1 to cause the problems of winding, interference fracture and the like when contracting and expanding, the main body part of the metal lead is arranged along the movement direction of the valve plate 2, avoiding the inner structure of the valve body 1 and allowing the metal lead to move along with the valve plate 2 so as to solve the problems.
Referring to fig. 2, the metal lead is disposed on the end surface of the receptor 31 facing away from the beam, so as to prevent the metal lead from directly contacting with the beam, and prevent a part of the beam from flowing to the receptor, thereby causing a problem of inaccurate measurement.
With continued reference to fig. 2, in order to implement installation of the metal lead, in this embodiment of the present disclosure, a first lead hole, a second lead hole, and a third lead hole are respectively and correspondingly provided on the valve plate 2, the first insulator 41, and the receiving body 31, and one end of the metal lead is sequentially inserted into the first lead hole, the second lead hole, and the third lead hole. When the receptor 31 is mounted on the groove 22, the centers of the first lead hole, the second lead hole and the third lead hole are overlapped, so that the metal leads can be conveniently penetrated in the first lead hole, the second lead hole and the third lead hole.
In the embodiment of the disclosure, the end of the metal lead is fixed in the third lead hole in a welding manner, and the end of the metal lead can partially penetrate out of the third lead hole for the convenience of welding. As a variant embodiment, riveting and terminal clamping can be adopted to prevent the welding process from forming welding spots on the end face of the receptor 31 facing the beam current to influence the detection result.
It will be appreciated that the metal lead needs to be connected to the receiving body 31 through a first lead hole, and that in order to prevent the current conducted on the metal lead from being directed to the valve plate through the wall of the first lead hole, the insulator 4 in the embodiment of the present disclosure further comprises a second insulator 42 disposed in the first lead hole for isolating the metal lead from the valve plate 2. For example, an insulating layer is protected over the metal lead and a vacuum sealer is applied within the first lead hole.
It will be appreciated that in the embodiment of the present disclosure, the gate valve is a vacuum gate valve, there may be unequal pressure differences between the left and right sides of the valve plate 2, and the pressure generated by the pressure differences acts on the receptor 31 via the metal lead and the second insulator 42, so that the receptor 31 is damaged or falls off. Preferably, the first insulator 424 is configured as a "T" shaped insulating sleeve, the edge of which is crimped on the end surface of the valve plate 2 facing away from the beam, and when a pressure difference exists, the pressure acts on the "T" shaped insulating sleeve, and the acting force is conducted to the valve plate 2 and does not act on the receptor 31.
It will be appreciated that, in order to ensure the effect of the valve plate 2 on the blocking of the pipeline, the gate valve in the embodiment of the present disclosure further comprises: and a sealing ring 5 is arranged on the end face of the valve plate 2 facing the beam, and the sealing ring 5 is arranged outside the groove 22.
As shown in fig. 4 and 5, the gate valve in this embodiment works as follows:
When the pipeline needs to be in a normal circulation state, as shown in fig. 4, the driving structure drives the valve plate 2 to ascend, after the preset ascending distance is reached, the center of the through hole 21 on the valve plate 2 is ensured to coincide with the center of the pipeline, and the beam in the pipeline flows into the pipeline at the rear through the through hole 21, as indicated by an arrow in the figure. At this time, the beam does not act on the measuring body 33 located above the via 21.
When the pipeline is required to be plugged, as shown in fig. 5, the driving structure drives the valve plate 2 to execute descending motion relative to the position shown in fig. 4, and after the preset distance is descended, the center of the sealing ring 5 on the valve plate 2 is ensured to be overlapped with the center of the pipeline, so that the plugging operation of the pipeline is completed. It should be noted that three positions may be provided on the valve plate 2 along the movement direction, and the via hole 21 in fig. 4 is located at the blocking position of the via hole 21 and at the beam intensity detection position above the blocking position. In fig. 5, in order to reduce the size of the valve plate 2 in the moving direction, the blocking position and the beam intensity detection position are designed to be the same position, and the beam is received by the receiver at the blocking position, thereby completing the detection of the intensity thereof.
In other embodiments, a single plugging position may be provided on the valve plate 2, so as to be used only when a pipeline is required to be plugged, and detection is not required.
The intensity of the beam detected by the receptor 31 of the metal copper sheet is that the magnitude of the current generated by the metal copper sheet is transmitted to the beam intensity detection mechanism through the guide body, and the accuracy of the current value is limited by the accuracy of the current value, and only the relative change of the beam intensity at the position can be fed back, so that the accurate detection of the beam intensity value cannot be realized.
Based on the above-described problem of detection accuracy, as shown in fig. 7 to 9, another gate valve is provided, the basic structure of which is substantially the same as that of the gate valve shown in fig. 1 to 6, except that:
as shown in fig. 7 and 8, the measuring body 3 in the present embodiment is configured as a faraday cage 6, and the faraday cage 6 has a function of accurately measuring the beam intensity. The valve plate 2 is provided with a through hole, the position of the nozzle of the Faraday cage 6 is arranged on the through hole, when the valve plate 2 is arranged at the beam intensity detection position, the position of the nozzle of the Faraday cage 6 faces the beam, and the beam flows through the through hole and enters the Faraday cage 6, so that the accurate measurement of the intensity of the beam is realized.
It will be appreciated that in order to prevent direct contact between the beam receiving drum in the faraday cage 6 and the valve plate 2, the insulator 4 is in embodiments of the disclosure configured as an insulating platen with one end disposed at the edge of the through-hole and one end disposed on the opening.
It can be understood that the axial center of the faraday cage 6 is coincident with the center of the valve plate 2, so as to further improve the accuracy of detecting the beam intensity.
As shown in fig. 9, a detection process of the beam intensity by the gate valve in the embodiment of the present disclosure is substantially the same as the detection process by the gate valve in fig. 1 to 6, and is not described herein. Since the faraday cage 6 has a certain length, which corresponds to an increase in the thickness of the valve plate 2, when the valve plate 2 is lifted, it is necessary to expand the width of the structure of the conventional valve body 1, as shown in fig. 9, the position of the faraday cage 6 at the broken line position, and the structure of the valve body 1 at the position needs to widen the accommodating space to prevent interference between the faraday cage 6 and the valve plate 2 when the valve plate 2 is lifted.
Embodiments of the present disclosure also provide an accelerator system comprising: a beam current transmission line 7; and a gate valve arranged on the beam transmission pipeline and used for detecting the intensity of the beam in the beam transmission pipeline and the opening and closing of the beam pipeline.
Although a few embodiments of the present general inventive concept have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
