Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve which is convenient for controlling flow. Background Art

[0002] A valve is a device used to control the flow of gases, liquids, gases or liquids containing solid powders in various pipelines and equipment. A valve is usually composed of a valve body, a valve cover, a valve seat, a start-stop part, a drive mechanism, a seal and fasteners. The control function of the valve is achieved by driving the start-stop part to lift, slide, swing or rotate by a drive mechanism or fluid to change the size of the flow area. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valves and other valve materials according to their materials. However, existing valves have some shortcomings, such as:

[0003] Announcement No.: CN217713848U is a valve for controlling flow. The device is convenient for installing the turntable on the transmission shaft by setting an installation structure, so as to facilitate use and avoid the inconvenience caused by non-professionals' random operation. However, in actual use, since the device is difficult to effectively lock the valve switch during the process of rotating the valve, the water flow may rush to the valve body and cause the valve switch of the device to twist automatically, thereby reducing the accuracy of the device in adjusting the valve;

[0004] Therefore, we propose a valve that is easy to control flow in order to solve the above problems. Utility Model Content

[0008] The worm is rotated to drive the turbine to rotate, and the turbine drives the threaded rod to rotate, so that the threaded rod rotates inside the threaded sleeve, and the threaded sleeve drives the block to rise and fall, thereby opening the gap in the middle of the baffle. When the worm is not rotating, the worm and the turbine have self-locking properties when they are engaged, so that the worm can lock the turbine to avoid the possibility of the turbine rotating on its own, thereby increasing the accuracy of the device during adjustment.

[0009] As the preferred technical solution of the utility model, a first bolt is connected to the left end of the valve body, and the left end of the valve body is fixedly connected to the liquid inlet flange through the first bolt, and a second bolt is connected to the right end of the valve body, and the valve body is fixedly connected to the liquid outlet flange through the second bolt.

[0010] The adoption of the above technical solution can make the valve body more stable when connected with the liquid inlet flange and the liquid outlet flange, thereby increasing the firmness of the device.

[0011] As a preferred technical solution of the present utility model, sealing bolts are provided on the outer side of the second sealing flange, and the second sealing flange is fixedly connected to the first sealing flange through the sealing bolts.

[0012] The adoption of the above technical solution can make the first sealing flange and the second sealing flange more secure when connected, thereby increasing the protection of the equipment.

[0013] As a preferred technical solution of the utility model, a sealing gasket is provided on the top of the connecting pipe, and the threaded sleeve passes through the sealing gasket and is threadedly connected to the threaded rod, and the threaded sleeve and the sealing gasket are slidably connected.

[0015] As a preferred technical solution of the utility model, a fixing box is provided on the top of the device tube, and the device tube is fixedly connected to the worm and the turbine through the fixing box.

[0016] The adoption of the above technical solution can make the device more secure when fixing devices such as a worm and a turbine, thereby increasing the stability of the device during adjustment.

[0017] As a preferred technical solution of the utility model, a group of valve switches are provided on the front side of the worm, and the valve switches are fixedly connected to the worm.

[0018] The adoption of the above technical solution can make it more convenient for the user to twist the worm, thereby increasing the operability of the device.

[0019] As a preferred technical solution of the utility model, a pressure relief port is provided at the bottom of the valve body, and the pressure relief port and the bottom of the valve body form a detachable threaded connection, and the pressure relief port can be set as an air leakage structure.

[0020] The above technical solution can discharge the air pressure inside the valve body through the pressure relief port when the pressure inside the valve body is too high, thereby avoiding the problem of excessive pressure inside the valve body affecting use.

[0021] Compared with the prior art, the utility model has the following beneficial effects: the turbine is driven to rotate by rotating the worm, so that the turbine drives the threaded rod to rotate, so that the threaded rod rotates inside the threaded sleeve, so that the threaded sleeve drives the block to rise and fall, thereby opening the gap in the middle of the baffle. When the worm does not rotate, the worm and the turbine have self-locking properties when meshing, so that the worm can lock the turbine, avoiding the possibility of the turbine rotating on its own, thereby increasing the accuracy of the device during adjustment.

[0022] Furthermore, by setting the valve switch, when the user turns the worm, the valve switch can drive the worm to rotate, so that the user can adjust the valve more conveniently.

[0023] Furthermore, by setting the pressure relief port, when the pressure inside the valve body is too high, the air pressure inside the valve body can be discharged from the pressure relief port, thereby avoiding the problem of excessive pressure inside the valve body affecting use.
