Description

Technical Field

[0001] This utility model relates to the field of control valve technology, and specifically to a combined control valve. Background Technology

[0002] A control valve, also known as a valve, is a control component in a fluid transport system. It functions to guide, cut off, regulate, throttle, prevent backflow, divert, or relieve pressure. It can be used to control various types of fluid flows, including air, water, steam, various corrosive chemical media, mud, liquid metals, and radioactive materials.

[0003] When installing control valves, they may be installed outdoors depending on the control requirements. However, outdoor control valves, lacking adequate protection, are susceptible to freezing in low winter temperatures, which can impair their control flexibility. Therefore, effectively preventing control valves from freezing in cold winter temperatures is a crucial issue that needs to be addressed in the design of modular control valves. Utility Model Content

[0004] This invention provides a combined control valve to solve the problem that control valves freeze due to low temperatures, thus affecting the flexibility of regulation.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a combined control valve, including a control valve, and further comprising:

[0007] A protective structure is provided on the control valve;

[0008] A top cover structure, wherein the top cover structure is mounted on the protective structure;

[0009] A snap-fit ​​structure is provided on both sides of the protective structure, and the top cover structure is fixed to the top of the protective structure through the snap-fit ​​structure.

[0010] Preferably, the protective structure includes a lower protective shell, an upper protective shell, a fixed arc plate, a first fixing block, a threaded rod, a nut, and a sealing gasket. The top of the upper protective shell is open. Fixed arc plates are fixedly connected to the side walls on opposite sides of the upper and lower protective shells. Sealing gaskets are fixedly connected to the inner side walls of the fixed arc plates. First fixing blocks are fixedly connected to the side walls on both sides of the fixed arc plates. Threaded rods are threadedly connected to the side walls of the first fixing block, and nuts are threadedly connected to both ends of the threaded rods.

[0011] In this technical solution, the upper and lower protective housings are fitted onto the outside of the control valve, the threaded rod is threaded onto the fixing block 1, and the nuts are threaded onto both ends of the threaded rod. Tightening these connections secures the upper and lower fixing blocks together, causing the fixing arc plate to press the sealing gasket tightly against the side wall of the control valve. This results in the upper and lower protective housings being fixedly connected to each other and fitted onto the outside of the control valve.

[0012] Preferably, two fixing blocks are fixedly connected to the side walls on both sides of the protective upper shell.

[0013] Preferably, the side wall of the second fixing block has a placement cavity.

[0014] Preferably, the snap-fit ​​structure includes a push block, a sliding rod, a second spring, a second sliding frame, a connecting rod, a snap-fit ​​block, and a fixing rod. The fixing rod is fixedly connected to the inner wall of the placement cavity. The side wall of the fixing rod is slidably connected to the snap-fit ​​block. The snap-fit ​​block is slidably connected to the side wall of the second fixing block. One end of the connecting rod is rotatably connected to the side wall of the snap-fit ​​block. The other end of the connecting rod is rotatably connected to the second sliding frame. The second sliding frame is slidably connected inside the placement cavity. The top of the second sliding frame is fixedly connected to the sliding rod. The sliding rod is slidably connected to the top side wall of the second fixing block. The top of the sliding rod is fixedly connected to the push block. A second spring is fixedly connected between the second sliding frame and the top inner wall of the placement cavity.

[0015] In this technical solution, the push block is pushed downward, causing the sliding rod to move downward. The sliding rod causes the second sliding frame to move downward, the second spring is stretched, the second sliding frame pushes the connecting rod to move, the connecting rod pushes the locking block to move, and the locking block moves outward along the fixed rod.

[0016] Preferably, the top cover structure includes a top cover, a handle frame, a sliding groove one, and a sliding groove two. The handle frame is fixedly connected to the side wall of the top cover. The length and width of the top cover are consistent with the length and width of the protective upper shell. A sliding groove one is provided on the side wall at the top of the handle frame, and two sliding grooves two are provided on the inner side walls on both sides of the handle frame.

[0017] In this technical solution, the top cover is fixed to the top side wall of the protective upper housing, and the control valve is completely covered inside by the protective upper housing, the protective lower housing, and the top cover for protection.

[0018] Preferably, the top cover structure includes a sliding frame, a sliding plate, and a spring. The sliding frame is slidably connected in two sliding grooves. The sliding plate is fixedly connected to the top side wall of the sliding frame. The sliding plate is slidably connected in the sliding groove. The spring is fixedly connected at equal distances between the sliding plate and the top inner side wall of the sliding groove.

[0019] In this technical solution, the hand grips the handle frame and the sliding frame 1. The sliding frame 1 moves upward, causing the sliding plate to move upward. The spring 1 is compressed, and the sliding frame 1 moves upward and no longer blocks the push block.

[0020] Preferably, the side walls at both ends of the handle frame are provided with snap-fit ​​grooves and square recesses.

[0021] Preferably, the square groove cooperates with the fixing block two, and the snap-fit ​​groove and the snap-fit ​​block cooperate with each other.

[0022] In this technical solution, the snap-fit ​​block snaps into the snap-fit ​​groove on the handle frame, so that the top cover is better fixed to the top side wall of the protective upper housing.

[0023] Preferably, the top cover, the upper protective shell, and the lower protective shell are all composed of a protective shell and a heat insulation layer. A cavity is formed in the side wall of the protective shell, and a heat insulation layer is fixedly installed in the cavity of the protective shell.

[0024] In this technical solution, the insulation layer can effectively insulate the internal cavities of the protective upper shell, the protective lower shell, and the top cover, preventing the control valve from freezing and affecting the flexibility of regulation when the temperature is too low in winter.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] 1. The protective upper shell and the protective lower shell are sleeved on the outside of the control valve, and the top cover is fixed on the top side wall of the protective upper shell. The control valve is completely covered inside by the protective upper shell, the protective lower shell and the top cover for protection. The insulation layer can effectively insulate the internal cavity of the protective upper shell, the protective lower shell and the top cover, so as to avoid the control valve from freezing when the temperature is too low in winter, which would affect the flexibility of regulation.

[0028] 2. By gripping the handle and sliding frame one, sliding frame one moves upward and no longer blocks the push block one. The stretched spring two retracts, causing sliding frame two to move upward. Sliding frame two pulls the locking block through the connecting rod, and the locking block leaves the locking groove and retracts into the cavity. The locking block no longer fixes or restricts the handle, thus the top cover is no longer fixed or restricted. Lifting the handle allows the top cover to be removed from the protective upper shell, making it convenient and quick to remove the top cover for control valve adjustment.

[0036] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0037] like Figure 1-5 As shown, the combined control valve includes control valve 1, and also includes:

[0038] Protective structure 2, wherein the protective structure 2 is disposed on the control valve 1;

[0039] Top cover structure 3, which is mounted on protective structure 2;

[0040] The snap-fit ​​structure 6 is provided on both sides of the protective structure 2, and the top cover structure 3 is fixed to the top of the protective structure 2 through the snap-fit ​​structure 6.

[0041] The protective structure 2 includes a lower protective shell 201, an upper protective shell 202, a fixed arc plate 203, a fixing block 204, a threaded rod 205, a nut 206, and a sealing gasket 207. The top of the upper protective shell 202 is open. The fixed arc plate 203 is fixedly connected to the side walls of the upper protective shell 202 and the lower protective shell 201 on opposite sides. The sealing gasket 207 is fixedly connected to the inner side wall of the fixed arc plate 203. Fixing blocks 204 are fixedly connected to the side walls on both sides of the fixed arc plate 203. The threaded rod 205 is threadedly connected to the side wall of the fixing block 204. The two ends of the threaded rod 205 are threadedly connected to the nuts 206.

[0042] By fitting the upper protective housing 202 and the lower protective housing 201 onto the outside of the control valve 1, and threading the threaded rod 205 onto the fixing block 204, and threading the nut 206 onto both ends of the threaded rod 205, the two fixing blocks 204 are tightly fixed together. This causes the fixing arc plate 203 to press the sealing gasket 207 tightly onto the side wall of the control valve 1, thereby fixing the upper protective housing 202 and the lower protective housing together and fitting them onto the outside of the control valve 1.

[0043] Two fixing blocks 4 are fixedly connected to the side walls on both sides of the protective upper shell 202.

[0044] The side wall of the second fixing block 4 has a placement cavity 5.

[0045] The snap-fit ​​structure 6 includes a push block 601, a sliding rod 602, a second spring 603, a second sliding frame 604, a connecting rod 605, a snap-fit ​​block 606, and a fixing rod 607. The fixing rod 607 is fixedly connected to the inner wall of the placement cavity 5. The side wall of the fixing rod 607 is slidably connected to the snap-fit ​​block 606. The snap-fit ​​block 606 is slidably connected to the side wall of the second fixing block 4. One end of the connecting rod 605 is rotatably connected to the side wall of the snap-fit ​​block 606. The other end of the connecting rod 605 is rotatably connected to the second sliding frame 604. The second sliding frame 604 is slidably connected inside the placement cavity 5. The top of the second sliding frame 604 is fixedly connected to the sliding rod 602. The sliding rod 602 is slidably connected to the top side wall of the second fixing block 4. The top of the sliding rod 602 is fixedly connected to the push block 601. The second spring 603 is fixedly connected between the sliding frame and the top inner wall of the placement cavity 5.

[0046] The push block 601 is pushed downward, causing the sliding rod 602 to move downward. The sliding rod 602 causes the second sliding frame 604 to move downward. The second spring 603 is stretched. The second sliding frame 604 pushes the connecting rod 605 to move. The connecting rod 605 pushes the locking block 606 to move. The locking block 606 moves outward along the fixed rod 607.

[0047] The top cover structure 3 includes a top cover 301, a handle bracket 302, a first sliding groove 303, and a second sliding groove 304. The handle bracket 302 is fixedly connected to the side wall of the top cover 301. The length and width of the top cover 301 are the same as the length and width of the protective upper shell 202. The first sliding groove 303 is provided on the side wall at the top of the handle bracket 302, and two second sliding grooves 304 are provided on the inner side walls on both sides of the handle bracket 302.

[0048] The top cover 301 is fixed to the top side wall of the protective upper housing 202, and the control valve 1 is completely covered inside by the protective upper housing 202, the protective lower housing 201 and the top cover 301 for protection.

[0049] The top cover structure 3 includes a sliding frame 311, a sliding plate 312, and a spring 313. The sliding frame 311 is slidably connected in two sliding grooves 304. The sliding plate 312 is fixedly connected to the top side wall of the sliding frame 311. The sliding plate 312 is slidably connected in the sliding groove 303. The spring 313 is fixedly connected at equal distances between the top inner side wall of the sliding plate 312 and the sliding groove 303.

[0050] The hand grips the handle 302 and the sliding bracket 311. The sliding bracket 311 moves upward, causing the sliding plate 312 to move upward. The spring 313 is compressed, and the sliding bracket 311 moves upward and no longer blocks the push block 601.

[0051] The handle bracket 302 has snap-fit ​​grooves 321 and square grooves 7 on the side walls at both ends.

[0052] The square groove 7 cooperates with the fixing block 4, and the snap-fit ​​groove 321 and the snap-fit ​​block 606 cooperate with each other.

[0053] The snap-fit ​​block 606 snaps into the snap-fit ​​groove 321 on the handle bracket 302, so that the top cover 301 is better fixed on the top side wall of the protective upper housing 202.

[0054] The top cover 301, the upper protective shell 202 and the lower protective shell 201 are all composed of a protective shell 2011 and a heat insulation layer 2012. A cavity is opened in the side wall of the protective shell 2011, and the heat insulation layer 2012 is fixedly installed in the cavity of the protective shell 2011.

[0055] The insulation layer 2012 can effectively insulate the internal cavities of the protective upper shell 202, the protective lower shell 201, and the top cover 301, preventing the control valve 1 from freezing and affecting the flexibility of regulation when the temperature is too low in winter.

[0056] In use, the protective upper housing 202 and the protective lower housing 201 are fitted onto the outside of the control valve 1, the threaded rod 205 is threaded onto the fixing block 204, and the nut 206 is threaded onto both ends of the threaded rod 205. Tightening these connections secures the two fixing blocks 204 together, causing the fixing arc plate 203 to press the sealing gasket 207 and secure it to the side wall of the control valve 1. This results in the protective upper housing 202 and the protective lower housing being fixedly connected to each other and fitted onto the outside of the control valve 1.

[0057] The snap-fit ​​block 606 snaps into the snap-fit ​​groove 321 on the handle bracket 302, so that the top cover 301 is better fixed on the top side wall of the protective upper shell 202. The control valve 1 is completely covered inside by the protective upper shell 202, the protective lower shell 201 and the top cover 301 for protection. The heat insulation layer 2012 can effectively insulate the internal cavity of the protective upper shell 202, the protective lower shell 201 and the top cover 301, so as to prevent the control valve 1 from freezing when the temperature is too low in winter, thus affecting the flexibility of regulation.

[0058] When adjusting the control valve 1, the hand grasps the handle bracket 302 and the sliding bracket 311. The sliding bracket 311 moves upward, causing the sliding plate 312 to move upward. The spring 313 is compressed, and the sliding bracket 311 moves upward and no longer blocks the push block 601. The stretched spring 603 retracts, causing the sliding bracket 604 to move upward. The sliding bracket 604 causes the sliding rod 602 and the connecting rod 605 to move upward. The sliding rod 602 pushes the push block 601 to move upward, and the connecting rod 605 pulls the locking block 606 to move. The locking block 606 slides along the fixed path, leaves the locking groove 321, and retracts into the placement cavity 5. The locking block 606 no longer fixes and restricts the handle bracket 302, so that the top cover 301 is no longer fixed and restricted. Lifting the handle bracket 302 allows the top cover 301 to be removed from the protective upper housing 202, making it convenient and quick to remove the top cover 301 for adjusting the control valve 1.
