Description

Technical Field

[0001] This utility model relates to the field of valve cover technology, specifically a valve cover with a bidirectional sealing structure. Background Technology

[0002] The valve cover is one of the main components of various valve types, including check valves, control valves, gate valves, and others. When installing the valve cover, it is generally connected and sealed with a sealing ring or gasket. However, the existing sealing ring or gasket has only a single working surface. When the operating environment changes, the sealing effect of the gasket changes and becomes unstable. At the same time, the existing valve cover does not have the function of shielding and protecting the nut, which means that the nut connected to the valve cover after it is fixed to the valve body is exposed to the environment and is prone to corrosion and rust. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a valve cover with a bidirectional sealing structure. This solves the problem mentioned in the background art, where existing valve covers are generally connected and sealed with sealing rings or gaskets when installed with the valve body. However, existing sealing rings or gaskets only have a single working surface. When the usage environment changes, the sealing effect of the gasket changes and the sealing effect becomes unstable. At the same time, existing valve covers do not have the function of shielding and protecting the nut, which leads to the nut being exposed to the environment after the valve cover and valve body are fixedly installed, making the nut susceptible to corrosion and rust.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a valve cover with a bidirectional sealing structure, comprising a valve cover structure, wherein a protective structure is provided on the surface of the valve cover structure;

[0005] The valve cover structure includes a valve cover body as the main body, and a sealing gasket is provided below the valve cover body, and a groove is provided on the surface of the sealing gasket.

[0006] An annular groove is provided on the inner side of the sealing gasket.

[0007] By adopting the above technical solution, the sealing gasket is set to achieve opening on the inside and outside.

[0008] Preferably, the protective structure includes a through-hole plate as the main body, and a bellows cover is fixedly installed at the bottom of the through-hole plate. At the same time, the through-hole plate is fixedly installed on the surface of the valve cover body.

[0009] By adopting the above technical solution, the valve cover body is installed to achieve a matching and fixed installation.

[0010] Preferably, the groove is rectangular in shape.

[0011] By adopting the above technical solution, the grooves created achieve the superposition of force compression.

[0012] Preferably, the depth range of the annular groove is set to 0.5-0.8 cm.

[0013] By adopting the above technical solution, the annular groove is created to achieve the effect of being squeezed and indented by force.

[0014] Preferably, the through-hole plate has an overall shape of "inner circle and outer square".

[0015] By adopting the above technical solution, the through-hole plate is used to achieve a matching and fixed installation.

[0016] Preferably, there are two sets of corrugated pipe covers, and the corrugated pipe covers are arranged symmetrically.

[0017] By adopting the above technical solution, the corrugated pipe cover provides protection.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the valve cover with a bidirectional sealing structure,

[0019] (1) This case solves the problem of the existing valve cover and valve body are generally connected and sealed by sealing rings or sealing gaskets when they are installed. However, the existing sealing rings or sealing gaskets only have a single working surface. When the usage environment changes, the sealing effect of the sealing gasket changes and the sealing effect is unstable. When the valve cover and valve body are sealed by the sealing gasket with grooves and annular grooves, the grooves and annular grooves are simultaneously subjected to pressure and compression during the pressure compression process. When the grooves and annular grooves are subjected to pressure and compression, the sealing gasket forms a double-layer structure inside and outside, which effectively achieves bidirectional sealing inside and outside.

[0020] (2) By setting up a protective structure, the existing valve cover does not have the function of shielding and protecting the nut, which leads to the nut being exposed to the environment after the valve cover and valve body are fixedly installed, which is prone to corrosion and rust. When the valve cover and valve body are fixedly installed, the operator can manually wrap the bellows cover and the fixed nut to avoid the fixed nut being exposed to the external environment.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a valve cover with a bidirectional sealing structure, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a valve cover structure 1, which comprises a valve cover body 101 as its main body. A sealing gasket 102 is disposed below the valve cover body 101, and a groove 103 is formed on the surface of the sealing gasket 102. The groove 103 is rectangular in shape. Because the structure is rectangular, it extends along the perimeter of the sealing gasket 102. By utilizing the groove 103 formed around the perimeter of the sealing gasket 102, the original single-sided sealing gasket 102 is transformed into a double-layer sealing gasket 102. The sealing gasket 102 provides a one-way double-layer seal to the outside. An annular groove 104 is provided on the inner side of the sealing gasket 102. The depth range of the annular groove 104 is set to 0.5-0.8cm. By setting the depth of the above structure to 0.5cm, it is possible to avoid the sealing gasket 102 from being easily penetrated when the depth of the above structure is too deep. Furthermore, the opening depth of the above structure is 0.5cm, which also effectively forms a double-layer setting on the inner side of the sealing gasket 102. When the sealing gasket 102 has double layers on both the inner and outer sides, it effectively provides a one-way double-layer seal to the inside and outside.

[0028] In the above scheme, when the valve cover 101 is installed with the valve body, the two of them squeeze the sealing gasket 102, the annular groove 104 and the groove 103, thereby making the sealing gasket 102 unidirectional double-layer seal both inside and outside.

[0029] like Figure 4As shown, a protective structure 2 is provided on the surface of the valve cover structure 1. The protective structure 2 includes a through-hole plate 201 as the main body. The through-hole plate 201 has an overall shape of "inner circle and outer square". When the above-mentioned components adopt the "inner circle and outer square" shape, it not only facilitates the through-fixation of the above-mentioned components to the surface of the valve cover body 101, but also effectively allows the bellows cover 202 installed below the through-hole plate 201 to cover the through-hole connection hole on the surface of the valve cover body 101, so as to facilitate the subsequent covering and protection of the fixing nut. The bellows cover 202 is fixedly installed at the bottom of the through-hole plate 201. There are two sets of bellows cover 202, and the bellows cover 202 is symmetrically arranged. When the above-mentioned components are arranged in two sets of four, it not only reflects the symmetry of the installation of the above-mentioned components, but also reflects the covering and protection of the installation of the above-mentioned components. When the above-mentioned components are arranged in two sets of four, it effectively reflects the practicality of the installation of the above-mentioned components. At the same time, the through-hole plate 201 is fixedly installed on the surface of the valve cover body 101.

[0030] In the above scheme, after the valve cover 101 is fixedly installed with the valve body, the operator can manually wrap and cover the bellows cover 202 with the fixing nut.
