DETAILED DESCRIPTION

[0036] Embodiment 1:

[0037] Please refer to Figures 1 to 11 As shown, the present invention provides a high-pressure sealing valve body, including a valve seat 1, sealing seats 111 are symmetrically arranged on both sides of the valve seat 1, and the outer sides of the two sealing seats 111 are fixedly connected to a connecting pipe 120; the outer sides of the two connecting pipes 120 are both slidably connected to a group of control racks 126 in an annular array; the inner sides of the two sealing seats 111 are both fixedly connected to a group of receiving guide rails 127 in an annular array; the two groups of receiving guide rails 127 are respectively aligned with the positions of the two groups of control racks 126; the inner sides of the two groups of control racks 126 are both fixedly connected to A group of connecting springs 128; the ends of the two groups of connecting springs 128 are respectively fixedly connected in the two groups of storage guide rails 127; the interiors of the two connecting tubes 120 are both rotatably connected with a group of connecting shafts 122 in a circular array; the exteriors of the two groups of connecting shafts 122 are both centrally fixedly connected with a group of clamping seats 123; the inner sides of the two groups of clamping seats 123 are both fixedly connected with rubber blocks 124; the exteriors of the two groups of connecting shafts 122 are both fixedly connected with a group of control gears 125; the two groups of control gears 125 are respectively meshed with the two groups of control racks 126.

[0038] It should be noted that the control rack 126 is squeezed by the external pipe, and the control rack 126 is pushed to the inner side of the receiving guide rail 127 under the action of the connecting spring 128. At this time, due to the meshing relationship between the control rack 126 and the control gear 125, the control gear 125 will drive the connecting shaft 122 to rotate, thereby causing the clamping seat 123 and the rubber block 124 inside thereof to move inward, until the rubber block 124 is tightly fitted on the sealing surface of the valve seat 1 to form an effective seal. When the valve body needs to be opened, the control rack 126 can be pushed by an external mechanism to overcome the elastic force of the connecting spring 128 and move outward. At this time, the control gear 125 will reverse, drive the connecting shaft 122 and the clamping seat 123 to move outward, and the rubber block 124 will leave the sealing surface, and the valve body can be opened. The operation is simple and fast, which is convenient for the staff to quickly install and fix the high-pressure sealing valve body, reduces the labor intensity of the staff, effectively improves the convenience of the high-pressure sealing valve body, and is more convenient to use.

[0039] Among them, a group of locking slots 129 are opened on the outer side of the two groups of control racks 126; a group of mounting slide blocks 130 are slidably connected in the two groups of storage guide rails 127; the head ends of the two groups of mounting slide blocks 130 are fixedly connected with locking wedges 131; the two groups of locking wedges 131 are respectively aligned with the positions of the two groups of locking slots 129; the outsides of the two groups of storage guide rails 127 are fixedly connected with a group of mounting frames 132; the ends of the two groups of mounting slide blocks 130 are fixedly connected with a group of return springs 133; the ends of the two groups of return springs 133 are respectively fixedly connected to the inner sides of the two groups of mounting frames 132.

[0040] It should be noted that in the design of the high-pressure sealing valve body, locking slots 129 are additionally provided on the outer sides of the two sets of control racks 126, and a mounting slider 130 and a locking wedge 131 thereon are slidably connected in the receiving guide rail 127, so as to further enhance the sealing stability and safety of the valve body;

[0041] During the installation process, the high-pressure sealing valve body is brought close to the pipeline in the area where the underwater vehicle is to be installed. As the connecting pipe and the pipeline inside the underwater vehicle are constantly approaching each other, the pipeline inside the underwater vehicle will squeeze the control rack 126. When the control rack 126 moves inward under the action of the connecting spring 128 and drives the clamping seat 123 and the rubber block 124 to fit tightly on the sealing surface of the valve seat 1, the locking wedge 131 will slide inward along the storage guide rail 127 under the elastic force of the return spring 133 until its front end is inserted into the corresponding locking slot 129, which not only further fixes the position of the control rack 126 and prevents it from accidentally moving due to external pressure or vibration, thereby ensuring the reliability of the seal; it also indicates that the valve body is currently in a sealed state;

[0042] When the valve body needs to be opened, the locking wedge 131 is first pulled out of the locking slot 129 to control the outward movement of the rack 126, and then the connecting shaft 122 and the clamping seat 123 are driven to rotate by the control gear 125, so that the rubber block 124 leaves the sealing surface.

[0043] In this embodiment, the outer sides of the two sets of mounting slide blocks 130 are fixedly connected with a set of mounting slide bars 134 ; the two sets of mounting slide bars 134 are respectively slidably connected in the two sets of mounting frames 132 ; the ends of the two sets of mounting slide bars 134 are fixedly connected with a set of auxiliary handles 135 .

[0044] It should be noted that in order to further facilitate operation and maintenance, installation slide bars 134 and auxiliary handles 135 are added to the outer sides of the two sets of installation slide bars 130, so that the operator can more easily control and operate the locking mechanism. When the valve body needs to be opened or closed, the operator can hold the auxiliary handle 135 to easily slide the installation slide bar 130 and the locking wedge 131 thereon along the installation slide bar 134 in the storage guide rail 127; this not only simplifies the locking and unlocking process, but also improves the accuracy and efficiency of the operation.

[0045] The top end surface of the valve seat 1 in this embodiment is boltedly connected to a gland 101; a valve stem 102 is rotatably connected inside the gland 101; the top end surface of the valve stem 102 is fixedly connected to a control hand wheel 103; the bottom end surface of the valve stem 102 is fixedly connected to a valve core ball 104; the valve core ball 104 is arranged in the valve seat 1.

[0046] It should be noted that when the operator rotates the control hand wheel 103, the valve stem 102 will rotate accordingly; since the valve stem 102 and the valve core ball 104 are fixedly connected, the valve core ball 104 will also rotate with the rotation of the valve stem 102. When the through hole on the valve core ball 104 is aligned with the flow channel on the valve seat 1, the valve is in an open state and the fluid can pass smoothly; when the through hole on the valve core ball 104 is offset from the flow channel on the valve seat 1, the valve is in a closed state and the fluid is cut off.

[0047] In this embodiment, one side of the two sealing seats 111 opposite to each other is fixedly connected with a flow tube 121; the two flow tubes 121 are both inserted into the valve seat 1; and the two flow tubes 121 are aligned with the position of the valve core ball 104; the outside of the valve seat 1 is symmetrically fixedly connected with two groups of first ear plates 109 in a circular array; the outer sides of the two groups of first ear plates 109 are fixedly connected with a group of fastening bolts 110.

[0048] The upper part of the valve seat 1 in this embodiment is fixedly connected to a water collecting seat 105 ; the top surface of the water collecting seat 105 is fixedly connected to a water retaining ring plate 106 ; the connection between the water retaining ring plate 106 and the gland 101 is aligned.

[0049] Among them, a float switch 107 is fastened and connected with the inner bolts of the water collecting seat 105; an alarm 108 is fastened and connected with the outer bolts of the water collecting seat 105; the position of the alarm 108 and the float switch 107 are aligned; and the alarm 108 and the float switch 107 are electrically connected.

[0050] It should be noted that a water collecting seat 105 is additionally provided on the upper part of the valve seat 1 for monitoring and warning of possible leakage of the valve. A water retaining ring plate 106 is fixedly connected to the top surface of the water collecting seat 105. The water retaining ring plate 106 is aligned with the connection position of the pressure cover 101, and is used to collect and guide the fluid medium that may leak from the valve. The water collecting seat 105 is internally bolted to a float switch 107, and the float switch 107 can float up and down with the rise and fall of the liquid level in the water collecting seat 105. When the valve leaks, the fluid medium flows into the water collecting seat 105 and causes the liquid level to rise, the float switch 107 will also rise and trigger its internal switch contacts. At the same time, the external bolts of the water collecting seat 105 are fastened to an alarm 108, and the alarm 108 is aligned with the position of the float switch 107, and the two are electrically connected to achieve signal transmission. When the float switch 107 triggers the switch contact, an electrical signal is sent to the alarm 108. After receiving the signal, the alarm 108 immediately sends out an audible and visual alarm to remind personnel to pay attention to possible leakage problems of the valve.

[0051] Among them, two fixed sleeves 116 are symmetrically fixedly connected in the valve seat 1; a group of feed springs 117 are fixedly connected to the inner sides of the two fixed sleeves 116; the ends of the two groups of feed springs 117 are fixedly connected to an auxiliary sealing sleeve 118; the two auxiliary sealing sleeves 118 are respectively slidably connected in the two fixed sleeves 116; the ends of the two circulation pipes 121 are respectively arranged in the two fixed sleeves 116; a sealing ring 119 is arranged in the two fixed sleeves 116; the two sealing rings 119 are respectively in contact with the two circulation pipes 121.

[0052] Among them, the outside of the two sealing seats 111 are fixedly connected with a group of second ear plates 114 in a circular array; the two groups of second ear plates 114 are respectively aligned with the positions of the two groups of first ear plates 109; the two groups of fastening bolts 110 are respectively arranged in the two groups of second ear plates 114; the outside of the two groups of fastening bolts 110 are threadedly connected with a group of fastening nuts 115.

[0053] It should be noted that two fixed sleeves 116 are symmetrically fixedly connected in the valve seat 1. The two fixed sleeves 116 not only provide a sliding track for the auxiliary sealing sleeve 118, but also provide continuous elastic support for the auxiliary sealing sleeve 118 through the internal feed spring 117. The end of the feed spring 117 is fixedly connected to the auxiliary sealing sleeve 118, so that the auxiliary sealing sleeve 118 can slide in the fixed sleeve 116 and fit tightly to the end of the flow pipe 121 as required to form an additional sealing layer; at the same time, a sealing ring 119 is provided in each of the two fixed sleeves 116, and the two sealing rings 119 are respectively connected to the two flow pipes 121. The contact further enhances the sealing performance between the circulation tube 121 and the valve seat 1. When the valve core ball 104 rotates to the closed state, the auxiliary sealing sleeve 118 and the sealing ring 119 work together to ensure that the fluid medium cannot leak from the gap between the circulation tube 121 and the valve seat 1; in addition, the outside of the two sealing seats 111 are fixedly connected to a group of second ear plates 114 in an annular array. The positions of these second ear plates 114 are aligned with the first ear plates 109, and a firm connection between the valve seat 1 and the sealing seat 111 is achieved through the combination of fastening bolts 110 and fastening nuts 115. It is not only simple and reliable, but also convenient for subsequent disassembly and maintenance.

[0054] Working principle:

[0055] By turning the control hand wheel 103, the control hand wheel 103 drives the valve stem 102 to rotate, and the rotation of the valve stem 102 drives the valve core ball 104 to rotate to control the opening and closing of the high-pressure sealing valve body. When the gland 101 and the valve seat 1 leak, the water collecting seat 105 will collect the leaked liquid to prevent the leaked liquid from polluting the surrounding environment. At the same time, the leaked liquid can be blocked by the setting of the water retaining ring plate 106 to prevent it from splashing. In the process of the water collecting seat 105 collecting the leaked liquid, the float switch 107 will float as the liquid level of the liquid collected in the water collecting seat 105 rises, and once the float switch 107 floats, the alarm 108 will be activated to make the alarm 108 sound a warning. , reminding the staff that there is leakage at the gland 101 of the high-pressure sealing valve body. When the valve core ball 104 is opened, the auxiliary sealing sleeve 118 will be pressed against the valve core ball 104 under the action of the elastic potential energy of the feed spring 117, and the valve core ball 104 is softly sealed. The setting of the sealing ring 119 can increase the direct sealing effect between the auxiliary sealing sleeve 118 and the flow pipe 121, and increase the sealing performance of the high-pressure sealing valve body to adapt to the working environment with higher fluid pressure. When the valve core ball 104 is closed, the valve core ball 104 will squeeze the auxiliary sealing sleeve 118, so that the auxiliary sealing sleeve 118 slides in the fixed sleeve 116 and squeezes the feed spring 117. At this time, the sealing ring 119 will be compressed under the action of its own elastic potential energy, and the sealing ring 119 will be rotated to The fastening nut 115 is tightened to move the fastening nut 115 along the fastening bolt 110. As the fastening nut 115 is continuously screwed, the second ear plate 114 is tightly fitted with the first ear plate 109 to ensure the sealing effect between the valve seat 1 and the sealing seat 111. During the installation of the high-pressure sealing valve body, as the connecting pipe 120 and the pipeline inside the underwater vehicle are constantly approaching, the pipeline inside the underwater vehicle will squeeze the control rack 126, causing the control rack 126 to slide in the connecting pipe 120 and squeeze the connecting spring 128. The excess control rack 126 can be stored by setting the storage guide rail 127. During the movement of the control rack 126, the control gear 125 meshing with it will be driven to move. The connecting shaft 122 is rotated by the rotation of the control gear 125, and the clamping seat 123 is turned over by the rotation of the connecting shaft 122, so that the clamping seat 123 is clamped on the outside of the flange of the pipeline, and the connecting pipe 120 and the pipeline are pressed tightly. At the same time, the setting of the rubber block 124 can increase the squeezing force of the clamping seat 123 on the pipeline flange, so that the connecting pipe 120 and the pipeline are tightly fitted to complete the installation of the high-pressure sealing valve body. When the control rack 126 slides in the receiving guide rail 127, the locking wedge 131 is squeezed, so that the locking wedge 131 drives the installation slider 130 to slide in the receiving guide rail 127 and squeeze the reset spring 133. When the locking slot 129 moves to the position of the locking wedge 131,Under the action of the elastic potential energy of the reset spring 133, the installation slider 130 will be reset. As the installation slider 130 is reset, the locking wedge 131 is inserted into the locking slot 129 to fix the control rack 126, and then the turned-over clamping seat 123 is locked and fixed to prevent the clamping seat 123 from rebounding. When the high-pressure sealing valve body needs to be replaced, the auxiliary handle 135 is pulled to drive the installation slide bar 134 to slide in the installation frame 132. As the installation slide bar 134 slides, the installation slider 130 drives the locking wedge 131 to disengage from the locking slot 129. At this time, the staff can flip the clamping seat 123 to release the fixation between the high-pressure sealing valve body and the pipeline inside the underwater vehicle.

[0056] Embodiment 2:

[0057] Based on Example 1, please refer to Figures 4 to 5 As shown, it includes: elastic blocks 112 and positioning grooves 113, the inner sides of the two sealing seats 111 are fixedly connected with a group of elastic blocks 112 in a circular array; the outer side of the valve seat 1 is symmetrically provided with two groups of positioning grooves 113 in a circular array; the two groups of elastic blocks 112 are aligned with the positions of the two groups of positioning grooves 113 respectively.

[0058] In this embodiment, the elastic block 112 is made of an elastic material, such as rubber or silicone, which mainly provides additional sealing effect and buffering effect to reduce the impact and vibration generated by the fluid medium when passing through the valve. The outside of the valve seat 1 is symmetrically provided with two groups of positioning grooves 113 in an annular array. The shape and size of the positioning grooves 113 match the elastic block 112, so that when the sealing seat 111 and the valve seat 1 are assembled, the elastic block 112 can be accurately embedded in the positioning groove 113, which not only ensures the precise positioning between the sealing seat 111 and the valve seat 1, but also further enhances the sealing effect between the two through the elastic deformation ability of the elastic block 112. When the valve is in a closed state, the valve core ball 104 fits tightly on the sealing seat 111, and the elastic block 112 can fill the tiny gap between the valve core ball 104 and the sealing seat 111 due to its own elastic deformation ability, thereby preventing leakage of the fluid medium. At the same time, the elastic block 112 can also absorb the impact and vibration generated when the fluid medium passes through the valve, protecting the internal structure of the valve from damage.

[0059] Specific usage and function of this embodiment: In the present invention, when the sealing seat 111 is connected to the valve seat 1, the elastic block 112 will first be inserted into the positioning groove 113 to position the sealing seat 111, so as to facilitate subsequent staff to connect and fix the sealing seat 111 and the valve seat 1.

[0060] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
