Description

Technical Field

[0001] The utility model relates to a regulating valve structure technical equipment, in particular to a regulating type modified asphalt regulating valve. Background Art

[0002] Modified asphalt refers to asphalt obtained by deep processing of coal tar or ordinary coal tar. It is a black solid at room temperature, and solidifies into a very brittle solid with a shell-like fracture at a certain temperature, showing a glass phase; it does not have a specific melting point, but melts within a certain melting point range, and has no thermal effect when solidifying. The components of asphalt are extremely complex, most of which are aromatic hydrocarbons with more than three rings, as well as heterocyclic compounds containing elements such as oxygen, nitrogen and sulfur, and a small amount of high molecular carbon substances.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0033] The application principle of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1 and Figure 2 As shown, it is an implementation scheme of the utility model, a control type modified asphalt regulating valve, comprising a valve body 1, a cavity is arranged in the valve body 1, and a spherical valve plate 2 is installed in the cavity, and the spherical valve plate 2 is "C" shaped; the upper and lower ends of the spherical valve plate 2 are installed with connecting parts 3, and the connecting parts 3 are respectively installed with a valve stem 4 and a bottom guide 5, and the bottom guide 5 is detachably fixed to the bottom of the valve body 1; a packing hole 6 is opened on the top of the valve body 1, and the lower end of the packing hole 6 is connected to the cavity, and a valve stem 4 is installed in the packing hole 6;

[0036] The two ends of the cavity are respectively a feed port 7 and a discharge port 8, a seal is installed at the feed port 7, a radial platform 9 is arranged inside the feed port 7, the radial platform 9 is connected to the seal, and the seal is movably connected to the spherical valve plate 2;

[0037] Compensation areas 21 are provided on both sides of the spherical valve plate 2 in a V shape, and the compensation area 21 is provided with a serrated edge line 22. Due to the different temperatures in the modified asphalt, the solid content of particles in different pipeline types is different, and some impurity particles are also included. The spherical valve plate will be washed during frequent use, causing wear of the valve plate. Therefore, the provision of a serrated spherical valve plate can, on the one hand, extend the length of the spherical valve plate and protect the connection effect between the spherical valve plate and the seal; on the other hand, it can cut or collide with some particulate matter to ensure the smoothness of the valve opening and closing during washing. The spherical valve plate 2 is also provided with a wear-resistant area 23, and the wear-resistant area 23 is movably abutted against the sealing ring 11. The wear-resistant area 23 can be a wear-resistant material or a sprayed wear-resistant material, such as Teflon material, to ensure wear resistance and not react with the modified asphalt.

[0038] A bottom sealing plate 14 is provided at the bottom of the bottom guide 5, and is fixed with a hexagonal bolt 15; a gasket 16 is installed between the bottom sealing plate 14 and the bottom guide 5.

[0040] Example 2

[0041] like Figure 3 As shown, it is another embodiment of the utility model. On the basis of Example 1, the sawtooth edge line 22 is located in the middle of the spherical valve plate 2, and the tooth thickness is higher than the tooth thickness near the two ends, and the tooth thickness gradually decreases from the middle to the two ends. Since the middle part of the spherical valve plate is opened first to cause contact when rotating, the gap is the first position to cause collision, and the gap is small and the extrusion is dense, which is more likely to cause collision and wear problems. Therefore, the sawtooth thickness in the middle position is increased to ensure strength.

[0042] Example 3

[0043] like Figure 4 and Figure 5 As shown, it is another implementation scheme of the utility model. On the basis of Example 1, the sealing member includes a pressure ring 10 and a sealing ring 11, and the pressure ring 10 is located on the outside of the sealing ring 11 and abuts against the sealing ring 11; the sealing member includes a pressure ring 10 and a sealing ring 11, and the pressure ring 10 is provided with a mounting hole 101, and the sealing ring 11 is provided with a mounting hole 2 111 on the side opposite to the pressure ring 10, and a spring 12 is installed between the mounting hole 101 and the mounting hole 2 111, and one end of the spring 12 is fixedly connected to the mounting hole 101, and the other end of the spring 12 is fixedly connected to the mounting hole 2 111.

[0044] The spring 12 is installed between the mounting hole 1 and the mounting hole 2 under compression, so after the spherical valve plate and the sealing ring 11 are worn, there is sufficient strength to support the sealing member 11 to maintain the sealing effect.

[0046] like Figure 6 and Figure 7 As shown, it is another embodiment of the present invention.

One side of the ring body 112 is fixedly connected to the radial platform 9, and a connecting cavity 114 is opened inside.

[0048] The pressure ring 10 is provided with a mounting hole 101, and the mounting hole 101 is communicated with the connecting cavity 114, and is connected with a spring 2 13, one end of the spring 2 13 is fixedly connected with the connecting ring portion 115, and the other end is fixedly connected with the mounting hole 101. A guide column is provided at the bottom of the ring body 1 and inserted into the ring body 2; and the height of the ring body 2 113 is lower than the height of the radial platform portion.
