Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an improved valve structure to prevent misoperation. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid transport systems and have functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, and their varieties and specifications are quite numerous.

[0003] In practical use, especially in environments with dense personnel and equipment, valve handles are easily touched or turned due to accidental factors such as people passing by or material handling collisions. Such accidental touches can lead to unintended rotation of the valve's opening and closing components, resulting in internal leakage of the medium, causing material loss, energy waste, or product contamination. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an improved valve structure to prevent misoperation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An improved valve structure to prevent misoperation includes a valve body, a circular base plate on the top of the valve body, an annular plate on the top end face of the base plate, a detachable protective cover for protecting the valve handle on the annular plate, and two opposing locking mechanisms on the outer wall of the annular plate.

[0007] The locking mechanism includes a housing with a receiving groove inside. A pressure plate is slidably connected in the receiving groove. A locking rod extending to the inner side of an annular plate is provided on one side of the pressure plate, and a connecting rod is provided on the other side of the pressure plate. A drive plate is provided on the outer side of the housing at the end of the connecting rod away from the pressure plate.

[0008] As a further embodiment of this invention, the outer wall of the protective cover is provided with a locking hole for inserting a locking rod.

[0009] As a further embodiment of this utility model, the inner wall of the annular plate is provided with two opposing positioning plates, and the bottom of the outer wall of the protective cover is provided with a positioning groove that matches the positioning plates.

[0010] As a further embodiment of this utility model, a return spring is coaxially sleeved on the outer side of the connecting rod and located in the receiving groove. One end of the return spring is fixedly connected to the pressure plate, and the other end of the return spring is fixedly connected to the inner side wall of the housing.

[0011] As a further embodiment of this utility model, a plurality of inclined reinforcing plates are provided between the bottom end face of the base plate and the valve body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The protective cover of this utility model can effectively isolate the valve handle from the external environment. Whether it is accidental contact by personnel passing by or collision during material handling, the handle cannot be directly contacted, thereby avoiding safety accidents such as accidental valve opening and closing, media leakage or production interruption caused by accidental contact.

[0022] Example

[0023] refer to Figures 1-5 An improved valve structure for preventing misoperation includes a valve body 1. The valve body 1 has a circular base plate 101 on its top. The top end face of the base plate 101 has an annular plate 102. A protective cover 103 for protecting the valve handle is detachably provided on the annular plate 102. Two oppositely arranged locking mechanisms 104 are provided on the outer wall of the annular plate 102. The locking mechanisms 104 make the installation and removal of the protective cover 103 simple and quick, without the need for any tools, which facilitates daily inspection and maintenance.

[0024] The locking mechanism 104 includes a housing 105, a receiving groove 106 is provided in the housing 105, a pressure plate 107 is slidably connected in the receiving groove 106, a locking rod 108 extending to the inner side of the annular plate 102 is provided on one side of the pressure plate 107, and a connecting rod 109 is provided on the other side of the pressure plate 107. The end of the connecting rod 109 away from the pressure plate 107 extends to the outer side of the housing 105 and is provided with a driving plate 110.

[0025] Furthermore, the outer wall of the protective cover 103 is provided with a locking hole 111 for the locking rod 108 to be inserted. By inserting the front end of the locking rod 108 into the locking hole 111 of the protective cover 103, the protective cover 103 is firmly locked from both sides by the locking rod 108, ensuring that it cannot be lifted up, thereby achieving reliable locking of the protective cover 103.

[0026] Furthermore, the inner wall of the annular plate 102 is provided with two opposing positioning plates 112, and the bottom of the outer wall of the protective cover 103 is provided with a positioning groove 113 that fits with the positioning plates 112. By the arrangement of the positioning plates 112 and the positioning groove 113, it can be ensured that the protective cover 103 is accurately and quickly installed in the predetermined position, so that the locking rod 108 can be accurately aligned with the locking hole 111.

[0027] Furthermore, a return spring 114 is coaxially sleeved on the outer side of the connecting rod 109 and located in the receiving groove 106. One end of the return spring 114 is fixedly connected to the pressure plate 107, and the other end of the return spring 114 is fixedly connected to the inner side wall of the housing 105. The spring force of the return spring 114 realizes the automatic locking of the protective cover 103. After the protective cover 103 is installed, it can automatically enter the protective state without additional locking operation.

[0028] Furthermore, a plurality of inclined reinforcing plates 115 are provided between the bottom end face of the base plate 101 and the valve body 1, and the reinforcing plates 115 enhance the structural strength of the connection between the base plate 101 and the valve body 1.

[0029] The working principle of this utility model:

[0030] During installation, first pull the drive plate 110 on the locking mechanism 104 outward. The drive plate 110 drives the pressure plate 107 outward via the connecting rod 109. At the same time, the pressure plate 107 compresses the return spring 114 until the front end of the locking rod 108 is completely retracted into the annular plate 102. Next, align the positioning groove 113 at the bottom of the protective cover 103 with the positioning plate 112 on the inner side of the annular plate 102, and insert it downward from above the valve handle to ensure that the protective cover 103 is accurately and quickly installed in the predetermined position. At this time, the locking rod 108 of the locking mechanism 104 is aligned with the locking hole 111 of the protective cover 103. Then, release the drive plate 110. Under the natural elastic force of the return spring 114, the return spring 114 pushes the pressure plate 107 to reset, and the pressure plate 107 then drives the locking rod 108 to move horizontally inward. Finally, the front end of the locking rod 108 is fully inserted into the locking hole 111 of the protective cover 103, and the protective cover 103 is firmly locked from both sides by the locking rod 108, ensuring that it cannot be lifted upwards, thereby achieving reliable locking of the protective cover 103. At this time, the valve handle is completely enclosed inside the protective cover 103, and even if personnel or equipment collide with the protective cover 103 when passing by, they will not be able to touch the handle inside.

[0031] During disassembly, first pull the drive plate 110 on the locking mechanism 104 outward until the locking rod 108 is completely disengaged from the locking hole 111 of the protective cover 103. At this point, the locking state of the protective cover 103 is released. Next, lift the protective cover 103 upward and remove it. After removing the protective cover 103, the valve handle can be operated normally.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
