Description

Technical Field

[0001] The utility model relates to the technical field of oxygen delivery, in particular to a novel oxygen-specific regulating valve. Background Art

[0002] Oxygen is one of the elements for the survival of animals and plants. Animals and plants need to breathe, inhale oxygen and then expel carbon dioxide for metabolism, but the role of oxygen is not limited to this. Oxygen is also used in both medicine and industry. For example, in industrial production, oxygen is used as a combustion aid or oxidant to play an auxiliary role. In medicine, oxygen is usually used to supply patients with vital signs. Whether in industrial production or medical fields, oxygen needs to be transported through pipelines to move oxygen from oxygen storage equipment or oxygen production equipment to oxygen-using equipment, and various valves are usually installed on the pipeline to control the flow, pressure, flow rate, on-off, etc. of oxygen. For example, a regulating valve is a common oxygen flow regulating device.

[0003] When some existing oxygen regulating valves are in use, the valves are installed on oxygen storage tanks to control on-off and flow. The control structure is usually a handwheel plunger type. Oxygen storage tanks are usually slender and placed together, or there are equipment around them. For example, oxygen storage tanks in medical facilities are placed next to oxygen machines. There are many pipes, equipment, power cords, other oxygen storage tanks and other items nearby, which may result in a small operating space for the valve, making it inconvenient for staff to operate the valve to adjust the flow. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a new oxygen-specific regulating valve to solve the technical problem of being inconvenient to use in a narrow space.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of oxygen-specific regulating valve, comprising a valve body and a handwheel, a control component is arranged on the top of the handwheel, and the control component comprises a bracket, a top plate is connected to the top of the bracket, a latch tooth is arranged on the outer ring of the bracket, a movable sleeve is connected to the top of the bracket, and a clamping frame is connected to the inside of the movable sleeve, a button is connected to the outer surface of the clamping frame through a linkage rod, a spring is sleeved on the outside of the linkage rod, and a handle is connected to the outer surface of the movable sleeve.

[0006] By adopting the above technical solution, first hold the handle and place a finger on the button surface. When the handwheel needs to be turned, hold the handle with force, and at the same time press the button with the finger to displace the button. After the button is displaced, the bracket is displaced through the linkage rod. At this time, the bracket and the latch teeth are against each other. Then, force is applied to the handle to rotate the movable sleeve. When the movable sleeve rotates, the torque is transmitted through the bracket and the latch teeth to drive the bracket to rotate. After the bracket rotates, the handwheel is driven to rotate. When the narrow operating space causes the handle to be unable to continue to rotate horizontally, do not hold the handle with force and stop pressing the button. At this time, the bracket, linkage rod and button are driven to reset by the spring, so the bracket and the latch teeth are separated and no torque is transmitted, so that the handle can return to the operable space alone for the next rotation. By reciprocating the above operation several times, the valve core can be adjusted to the specified position to control the flow or on and off of oxygen.

[0007] Furthermore, the movable sleeve is rotatably connected to the bracket and the top plate respectively, and the button and the linkage rod are slidably connected to the handle.

[0008] By adopting the above technical solution, the user holds the handle with force and presses the button with his fingers to move the button. After the button is moved, the card frame is moved through the linkage rod, and then the user applies force to the handle to rotate the movable sleeve.

[0009] Furthermore, the clamping frame abuts against the clamping teeth, and the clamping frame is slidably connected to the movable sleeve.

[0010] By adopting the above technical solution, the clamping frame and the clamping teeth are against each other, so when the movable sleeve rotates, the torque is transmitted through the clamping frame and the clamping teeth to drive the bracket to rotate.

[0011] Furthermore, the latching teeth are provided in plurality, and the plurality of latching teeth are distributed in a ring array.

[0012] By adopting the above technical solution and providing a plurality of latching teeth, the latching frame can transmit torque against the latching teeth after being reset by the spring no matter to which angle it is rotated.

[0013] Furthermore, a limiting plate is connected to the bottom of the bracket, a nut is connected inside the limiting plate, and a bolt passes through one side of the limiting plate.

[0014] By adopting the above technical solution, after the bracket rotates, the handwheel is driven to rotate through the limit plate, and the rotation of the handwheel drives the valve stem to rotate, thereby causing the valve core to move upward or downward in the valve body to adjust the oxygen flow or on and off. Due to the setting of the limit plate and the bolt, the control component is prevented from falling off the handwheel, and the control component can be replaced after being damaged.

[0015] Furthermore, the limiting plates, bolts and nuts are provided in plurality, and the plurality of limiting plates, bolts and nuts are distributed in a ring array.

[0016] By adopting the above technical solution, due to the setting of the limit plate and the bolt, the control component is prevented from falling off the handwheel, and the control component can be replaced after being damaged.

[0017] Furthermore, the limit plate and the bolt are both in contact with the hand wheel, and the nut is fixedly connected to the limit plate.

[0018] By adopting the above technical solution, the limiting of the limiting plate is ended by removing the bolts, and then the control component can be removed and replaced by lifting the bracket upwards.

[0019] Furthermore, a valve seat is connected to the top of the valve body, and a valve stem passes through the top of the valve seat, a valve core is connected to the bottom of the valve stem, the handwheel is connected to the top of the valve stem, an oxygen inlet is provided on one side of the valve body, and an oxygen outlet is provided on the other side of the valve body.

[0020] By adopting the above technical solution, the rotation of the handwheel drives the valve stem to rotate, thereby causing the valve core to move upward or downward in the valve body to adjust the oxygen flow rate. Oxygen enters the valve body from the oxygen storage tank through the oxygen inlet, and then the valve core controls the on-off and flow rate. When oxygen passes through the valve core, it can be discharged from the oxygen outlet into the oxygen supply pipe.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model adopts the setting of the control component, firstly, the hand holds the handle and places a finger on the button surface, when the hand wheel needs to be turned, the hand holds the handle with force, and at the same time, the finger presses the button to displace the button, after the button is displaced, the clamping frame is displaced through the linkage rod, at this time, the clamping frame and the clamping teeth are against each other, and then the movable sleeve is rotated by applying force to the handle, when the movable sleeve rotates, the torque is transmitted through the clamping frame and the clamping teeth to drive the bracket to rotate, and after the bracket rotates, the hand wheel is driven to rotate, when the narrow operating space causes the handle to be unable to continue to rotate horizontally, the handle is not held with force and the button is stopped, at this time, the clamping frame, the linkage rod and the button are driven to reset by the spring, so that the clamping frame is separated from the clamping teeth and no torque is transmitted, so that the handle can be returned to the operable space alone for the next rotation, and the valve core can be adjusted to the specified position to control the flow rate or on-off of oxygen by reciprocating the above operations several times; it is convenient to operate in a narrow space, and the increased force arm has a labor-saving effect.

After the bracket 801 rotates, the hand wheel 7 is driven to rotate through the limit plate 9; the outer surface of the bracket 808 is connected to the button 805 through the linkage rod 806, and the outer side of the linkage rod 806 is sleeved with a spring 807. The button 805 and the linkage rod 806 are both slidably connected to the handle 804, and the outer surface of the movable sleeve 802 is connected to the handle 804. After the button 805 is displaced, the bracket 808 is driven to displace through the linkage rod 806, and at this time, the bracket 808 and the latch tooth 809 are against each other.

[0034] See also Figure 1 and Figure 5In the above embodiment, a valve seat 2 is connected to the top of the valve body 1, a valve stem 3 passes through the top of the valve seat 2, a valve core 4 is connected to the bottom of the valve stem 3, a hand wheel 7 is connected to the top of the valve stem 3, an oxygen inlet 5 is provided on one side of the valve body 1, and an oxygen outlet 6 is provided on the other side of the valve body 1. The oxygen inlet 5 is connected to the oxygen storage tank, and the oxygen outlet 6 is connected to the oxygen supply pipe. After the regulating valve is opened, oxygen enters the valve body 1 from the oxygen storage tank through the oxygen inlet 5, and when the oxygen passes through the valve core 4, it can be discharged from the oxygen outlet 6 into the oxygen supply pipe.

[0035] Embodiment 2:

[0036] Based on the above embodiment 1, refer to Figure 1-Figure 4 A limiting plate 9 is connected to the bottom of the bracket 801, and a bolt 10 passes through one side of the limiting plate 9. The limiting plate 9 and the bolt 10 are both in contact with the handwheel 7. A nut 11 is connected inside the limiting plate 9, and the nut 11 is fixedly connected to the limiting plate 9. There are multiple limiting plates 9, bolts 10 and nuts 11, and the multiple limiting plates 9, bolts 10 and nuts 11 are distributed in a ring array. Due to the setting of the limiting plate 9 and the bolt 10, the control component 8 is prevented from falling off the handwheel 7, and the control component 8 can be replaced after it is damaged.

[0037] The implementation principle of the utility model is as follows: first, the user connects the oxygen inlet 5 to the oxygen storage tank, and the oxygen outlet 6 to the oxygen supply pipe. After the regulating valve is opened, oxygen enters the valve body 1 from the oxygen storage tank through the oxygen inlet 5, and when the oxygen passes through the valve core 4, it can be discharged from the oxygen outlet 6 into the oxygen supply pipe;

[0038] When it is necessary to adjust the oxygen flow or close the regulating valve, the user first holds the handle 804 and places a finger on the surface of the button 805. When it is necessary to turn the handwheel 7, the user holds the handle 804 with force and presses the button 805 with his finger to displace the button 805. After the button 805 is displaced, the bracket 808 is displaced through the linkage rod 806. At this time, the bracket 808 and the latching teeth 809 are against each other. Then, the user applies force to the handle 804 to rotate the movable sleeve 802. When the movable sleeve 802 rotates, the torque is transmitted through the bracket 808 and the latching teeth 809 to drive the bracket 801 to rotate. After the bracket 801 rotates, the handwheel 7 is driven to rotate through the limit plate 9. The rotation of the handwheel 7 drives the valve stem 3 to rotate, thereby causing the valve core 4 to move upward or downward in the valve body 1 to adjust the oxygen flow or switch on and off. Due to the setting of the limit plate 9 and the bolt 10, the control component 8 is prevented from falling off from the handwheel 7, and the control component 8 can be replaced after it is damaged.

[0039] When the narrow operating space makes it impossible for the handle 804 to continue to rotate horizontally, the user no longer holds the handle 804 tightly and stops pressing the button 805. At this time, the spring 807 drives the bracket 808, the linkage rod 806 and the button 805 to reset, so that the bracket 808 is separated from the latch tooth 809 and no longer transmits torque. Then the user applies an opposite force to the handle 804, so that the handle 804 returns to the operable space alone for the next rotation. By reciprocating the above operation several times, the valve core 4 can be adjusted to the specified position to control the flow or on / off of oxygen.
