Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage control valve technology, specifically to a novel connection control valve for water supply and drainage design. Background Technology
[0002] A drain control valve is a device used to regulate and control the flow of liquids. It is mainly used in drainage systems. It can adjust the flow rate in the pipeline to ensure drainage or fluid control when needed, and prevent excessive flow or excessive pressure.
[0003] Chinese patent discloses a novel connection control valve for water supply and drainage design (Publication No.: CN215806418U). This device, through an adjustment mechanism, allows the user to adjust the valve when drainage is needed. Pulling the adjustment rod causes it to displace spring A, generating elastic force. The adjustment rod then disengages from the inner wall of the adjustment hole, releasing the rotating rod. This releases the rotating wheel, causing the rotating rod to rotate. The rotating rod then drives a gear, which in turn moves a rack, which in turn moves the valve plate, thus adjusting the device and stably restricting the control valve. This prevents the valve from rotating due to water flow impact, a common problem in many control valves. However, the device still has the following issues during use:
[0004] The aforementioned device limits the rotation of the rotating rod by inserting the adjusting rod into the inner wall of the adjusting hole, thereby adjusting and controlling the opening and closing of the valve plate. Although the device fixes the opening and closing of the valve plate to prevent water flow from affecting the device, it is more troublesome to adjust the valve closure because it requires both fixing and unfixing steps during adjustment. Utility Model Content
[0005] The technical problem to be solved by this utility model is as follows:
[0006] Valve adjustment is complicated because it requires taking into account both the steps of releasing and fixing the valve.
[0007] The objective of this utility model can be achieved through the following technical solutions:
[0008] A novel connection control valve for water supply and drainage design includes a control valve body, and an adjustment mechanism is provided on the top of the control valve body;
[0009] Its characteristic is that it further includes:
[0010] The adjusting mechanism includes a connecting seat, a rotating rod rotatably connected to the middle of the inner wall of the connecting seat, the bottom end of the rotating rod passing through the connecting seat, and valve baffles fixedly installed on both sides of the bottom outer wall of the rotating rod, with the valve baffles on both sides arranged symmetrically.
[0011] The top end of the rotating rod passes through the connecting seat, and springs are fixedly installed on both sides of the top outer wall of the rotating rod. On one side, the end of the spring away from the rotating rod is fixedly connected to a slider one, and on the other side, the end of the spring away from the rotating rod is fixedly connected to a slider two.
[0012] Both slider one and slider two are fixedly connected to ratchet pawls at the outer wall ends away from the spring, and the ratchet pawls on the outer walls of slider one and slider two are arranged in opposite directions, and the lowest point of the ratchet pawl on the outer wall of slider one is located above the highest point of the ratchet pawl on the outer wall of slider two.
[0013] As a further embodiment of this utility model: the outer wall of the rotating rod and the outer side of slider one and slider two are fixedly connected to limit plates. Two limit plates are provided and are symmetrically arranged. The inner side of the outer wall of the limit plates on both sides is slidably connected to slider one and slider two.
[0014] As a further embodiment of this utility model: a top cover is rotatably connected to the top of the connecting seat and outside the slider one and slider two. The inner wall of the top cover is hollowed out, and a ratchet two is fixedly installed at the bottom of the inner side wall of the top cover. A ratchet one is fixedly connected to the inner side wall of the top cover and above the ratchet two.
[0015] As a further embodiment of this utility model: ratchet one and ratchet two have ratchet teeth arranged in a ring on their inner sidewalls, and the ratchet teeth on the inner wall of ratchet one and ratchet two face opposite directions. The ratchet one is engaged with the pawl of slider one at the ratchet teeth on its inner wall, and the ratchet two is engaged with the pawl of slider two at the ratchet teeth on its inner wall.
[0016] As a further embodiment of this utility model: both slider one and slider two have grooves on their tops, and one side of the inner wall of the groove of both slider one and slider two is set as an inclined surface, and the inclined surfaces of slider one and slider two face opposite directions.
[0017] As a further embodiment of this utility model: a control rod is rotatably connected to the top center of the top cover, the bottom end of the control rod passes through the top cover and is fixedly connected to a rotating plate, and push shafts are fixedly connected to both sides of the bottom of the rotating plate. The outer wall of the bottom end of the push shaft on one side is slidably connected to the inner wall of the groove of slider one, while the outer wall of the bottom end of the push shaft on the other side is slidably connected to the inner wall of the groove of slider two.
[0018] As a further embodiment of this utility model: the control valve body includes a valve shell, with connecting pipes extending through both sides of the outer wall of the valve shell, a limiting shaft fixedly connected to the bottom center of the inner wall of the valve shell, the outer side wall of the limiting shaft being movably connected to a valve baffle, the middle part of the inner wall of the valve shell being rotatably connected to a rotating rod, and the inner side wall of the valve shell being slidably connected to the valve baffle.
[0019] The beneficial effects of this utility model are:
[0020] (1) This utility model controls the water flow through the control valve by rotating the rod to drive the valve baffles on both sides to flip. The top two sides of the rotating rod are provided with pawls, and ratchet wheels with different orientations are provided on the outer wall of each pawl. This makes it impossible for the valve baffles to drive the rotating rod to move when the pawls and ratchet wheels are engaged with each other, thereby preventing the water flow through the control valve from affecting the opening and closing of the valve baffles.
[0021] (2) An adjustment mechanism is set above the main body of the control valve. When it is necessary to switch or adjust the opening and closing of the valve baffle, you only need to turn the top control rod directly to drive the valve baffle below to rotate gradually. When you stop turning the control rod, the water flow will not affect the valve baffle, which is convenient for operation and use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figure 1-5 As shown, a novel connection control valve for water supply and drainage design includes a control valve body 1, with an adjusting mechanism 2 mounted on the top of the control valve body 1; it also includes: wherein the adjusting mechanism 2 includes a connecting seat 201, a rotating rod 209 rotatably connected to the middle of the inner wall of the connecting seat 201, the bottom end of the rotating rod 209 passing through the connecting seat 201, and valve baffles 210 fixedly installed on both sides of the bottom outer wall of the rotating rod 209, the valve baffles 210 being symmetrically arranged on both sides; wherein the top end of the rotating rod 209 passes through the connecting seat 201, and the top outer wall of the rotating rod 209 is fixedly installed on both sides of the bottom outer wall. Springs 211 are fixedly installed on both sides. On one side, a slider 212 is fixedly connected to the end of spring 211 furthest from the rotating rod 209. On the other side, a slider 213 is fixedly connected to the end of spring 211 furthest from the rotating rod 209. Both sliders 212 and 213 have ratchet pawls fixedly connected to their outer walls furthest from springs 211. The ratchet pawls on the outer walls of sliders 212 and 213 face opposite directions, and the lowest point of the ratchet pawl on the outer wall of slider 212 is located above the highest point of the ratchet pawl on the outer wall of slider 213. Figures 3-4 As shown, the springs 211 on both sides push slider 1 212 and slider 2 213 to move outward, so that slider 1 212 and slider 2 213 engage with ratchet 1 206 and ratchet 2 207 respectively.
[0031] Limiting plates 208 are fixedly connected to the outer wall of the rotating rod 209, located outside the first slider 212 and the second slider 213. Two limiting plates 208 are provided symmetrically. The inner sides of the outer walls of the two limiting plates 208 are slidably connected to the first slider 212 and the second slider 213. Figure 4 As shown, the limiting plate 208 limits the movement trajectory of slider 1 212 and slider 2 213;
[0032] A top cover 202 is rotatably connected to the top of the connecting seat 201 and outside the slider 1 212 and slider 2 213. The inner wall of the top cover 202 is hollow, and a ratchet 207 is fixedly installed on the bottom of the inner side wall of the top cover 202. A ratchet 1 206 is fixedly connected to the inner side wall of the top cover 202 above the ratchet 207. Both ratchet 1 206 and ratchet 207 have ratchet teeth arranged in a ring on their inner side walls. The ratchet teeth on the inner wall of ratchet 1 206 face opposite directions to the ratchet teeth on the inner wall of ratchet 207. The ratchet 1 206 engages with the pawl of slider 1 212 at the ratchet teeth on its inner wall, and the ratchet 207 engages with the pawl of slider 2 213 at the ratchet teeth on its inner wall. Figures 3-4 As shown, ratchet 1 206 and ratchet 2 207 limit the rotation rod 209 in different directions through pawls;
[0033] Both slider 1 (212) and slider 2 (213) have grooves on their tops, and one side of the inner wall of the grooves of both slider 1 (212) and slider 2 (213) is set as a slope, with the slopes of slider 1 (212) and slider 2 (213) facing opposite directions. Figures 4-5 As shown, the push shaft 205 pushes the inclined surfaces of slider 1 212 and slider 2 213, thereby pushing slider 1 212 and slider 2 213 to move inside the limiting plate 208.
[0034] A control rod 203 is rotatably connected to the top center of the top cover 202. The bottom end of the control rod 203 passes through the top cover 202 and is fixedly connected to a rotating plate 204. Push shafts 205 are fixedly connected to both sides of the bottom of the rotating plate 204. The outer wall of the bottom end of one push shaft 205 is slidably connected to the inner wall of the groove of slider one 212, while the outer wall of the bottom end of the other push shaft 205 is slidably connected to the inner wall of the groove of slider two 213. Figure 4 As shown, the push shaft 205 pushes the inclined surfaces of slider 1 212 and slider 2 213 during rotation;
[0035] The control valve body 1 includes a valve housing 101. Connecting pipes 102 are connected through the outer walls of the valve housing 101 on both sides. A limiting shaft 103 is fixedly connected to the bottom center of the inner wall of the valve housing 101. The outer wall of the limiting shaft 103 is movably connected to a valve baffle 210. The middle of the inner wall of the valve housing 101 is rotatably connected to a rotating rod 209, and the inner wall of the valve housing 101 is slidably connected to the valve baffle 210. Figure 2 As shown, the limiting shaft 103 blocks the valve baffle 210, thereby limiting the rotation angle of the rotating rod 209.
[0036] The working principle of this utility model:
[0037] When the device is in use, the connecting pipes 102 on both sides are connected to the inlet pipe and the outlet pipe respectively. When it is necessary to adjust the flow rate of the liquid passing through the control valve body 1, the control rod 203 is rotated first, which drives the rotating plate 204 to rotate. As a result, the push shafts 205 on both sides move in the top grooves of slider 1 212 and slider 2 213 respectively. When the push shafts 205 move, they push the inclined surface on one side of the groove of slider 1 212 and slider 2 213, so that slider 1 212 and slider 2 213 are subjected to the force in the length direction of the limiting plate 208. As a result, slider 1 212 and slider 2 213 rotate toward the rotating rod 209 under the constraint of the limiting plate 208. At this time, the spring 211 is compressed and stores elastic potential energy, and slider 1 212 and slider 2 213 separate from ratchet 1 206 and ratchet 2 207 respectively during the movement.
[0038] Secondly, with slider 1 212 and slider 2 213 separated from ratchet 1 206 and ratchet 2 207, the rotating plate 204 continues to drive the push shaft 205 to rotate, which in turn pushes the limiting plate 208, causing the limiting plate 208 and the rotating rod 209 to rotate. The limiting plate 208 then pushes the internal slider 1 212 and slider 2 213 to rotate. Under the push of the spring 211, the pawls on the sides of slider 1 212 and slider 2 213 re-engage with ratchet 1 206 and ratchet 2 207. By repeating the above steps, the rotating rod 209 gradually rotates and drives the valve baffle 210 to rotate inside the valve housing 101, thereby changing the area of controllable liquid flow inside the control valve body 1.
[0039] Furthermore, when the flowing liquid directly impacts the valve baffle 210, the rotating rod 209 cannot be pushed because the slider 1 212 and slider 213 on both sides of the rotating rod 209 are engaged with the ratchet 1 206 and ratchet 207 respectively.
[0040] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
