Description

Technical Field

[0001] This utility model relates to the field of cylinder head sealing technology, and in particular to a reinforced sealing structure for cylinder heads. Background Technology

[0002] A cylinder is a cylindrical metal component that guides a piston in a linear reciprocating motion within the cylinder. In an engine cylinder, air expands, converting thermal energy into mechanical energy; in a compressor cylinder, gas is compressed by the piston, increasing its pressure. To prevent leaks caused by gaps between the cylinder block and cylinder head, a seal is required.

[0003] Traditional cylinder head and cylinder block sealing structures typically use a set of sealing gaskets for sealing. The sealing line is relatively simple, and when a local failure occurs, it will affect the overall sealing performance. Moreover, it is not easy to increase the contact pressure between the sealing gasket and the cylinder head. Over time, the contact may become loose, leading to leakage. Utility Model Content

The stainless steel gasket is fixedly disposed on the bottom surface of the outer sealing frame, and the graphite gasket is fixedly disposed on the bottom surface of the stainless steel gasket. The stainless steel gasket and the graphite gasket are used to seal the connection between the outer sealing frame and the outer sealing channel.

[0014] (III) Beneficial Effects

[0015] This utility model provides a reinforced sealing structure for cylinder heads, which has the following beneficial effects:

[0016] 1. The cylinder head uses a reinforced sealing structure. Through the setting of silicone sealing gasket, titanium alloy memory spring sheet and connecting cover assembly, the connecting cover assembly is inserted into the insertion channel. The main cover and sealing strip increase the contact area with the silicone sealing gasket, forming multiple sealing lines. Even if there is a partial failure, there is still a redundant sealing path, resulting in good sealing effect. The titanium alloy memory spring sheet increases the contact pressure between the silicone sealing gasket and the connecting cover assembly, further enhancing the sealing performance.

[0017] 2. The cylinder head uses a reinforced sealing structure. With the setting of the outer sealing frame and sealing components, when the cylinder head is connected to the cylinder body, the outer sealing frame is inserted into the outer sealing channel.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a reinforced sealing structure for cylinder heads, including a cylinder body 1, an insertion channel 2 on the top surface of the cylinder body 1, a silicone sealing gasket 3 fixedly disposed on the inner wall of the insertion channel 2, a plurality of cavities being formed inside the silicone sealing gasket 3, a titanium alloy memory spring sheet 4 being fixedly disposed inside the cavity, and a connecting cover assembly 5 being inserted into the insertion channel 2. By setting up the silicone sealing gasket 3, the titanium alloy memory spring sheet 4 and the connecting cover assembly 5, the connecting cover assembly 5 is inserted into the insertion channel 2. The main sealing cover 501 and the sealing strip 502 increase the contact area with the silicone sealing gasket 3, forming multiple sealing lines. Even if there is a partial failure, there is still a redundant sealing path, resulting in a good sealing effect. The titanium alloy memory spring sheet 4 increases the contact pressure between the silicone sealing gasket 3 and the connecting cover assembly 5, further enhancing the sealing performance.

[0026] A cylinder head 6 is fixedly installed on the top of the connecting cover assembly 5. An outer sealing frame 7 is fixedly installed on the edge of the bottom surface of the cylinder head 6. A sealing component 8 is fixedly installed on the bottom surface of the outer sealing frame 7. With the setting of the outer sealing frame 7 and the sealing component 8, when the cylinder head 6 is connected to the cylinder body 1, the outer sealing frame 7 is inserted into the outer sealing channel 9. The stainless steel gasket 801 and the graphite gasket 802 seal the bottom surface of the contact part between the outer sealing frame 7 and the outer sealing channel 9. Together with the silicone sealing gasket 3, a double seal is formed inside and outside, which makes the sealing effect between the cylinder head 6 and the cylinder body 1 better.

[0027] The connecting cover assembly 5 includes a main cover 501 and a sealing strip 502. The main cover 501 is inserted into the inside of the insertion channel 2. There are three sets of sealing strips 502, which are fixedly arranged on the surface of the main cover 501 from top to bottom.

[0028] By connecting the cover assembly 5, the main cover 501 and the sealing strip 502 increase the contact area with the silicone sealing gasket 3, forming multiple sealing lines. Even if there is a partial failure, there are still redundant sealing paths, resulting in a good sealing effect.

[0029] The sealing component 8 includes a stainless steel gasket 801 and a graphite gasket 802. The stainless steel gasket 801 is fixedly disposed on the bottom surface of the outer sealing frame 7, and the graphite gasket 802 is fixedly disposed on the bottom surface of the stainless steel gasket 801.

[0030] By setting the sealing component 8, the stainless steel gasket 801 and the graphite gasket 802 seal the bottom surface of the contact area between the outer sealing frame 7 and the outer sealing channel 9, forming a double seal inside and outside in conjunction with the silicone sealing gasket 3.

[0031] An outer sealing channel 9 is provided on the edge of the top surface of the cylinder body 1, and the outer sealing channel 9 is adapted to the outer sealing frame 7.

[0032] The outer sealing channel 9 facilitates the insertion of the outer sealing frame 7.

[0033] The number of titanium alloy memory spring sheets 4 is several sets, and the several sets of titanium alloy memory spring sheets 4 are distributed in a rectangular array inside the silicone sealing gasket 3.

[0034] By setting the titanium alloy memory spring sheet 4, the contact pressure between the silicone sealing gasket 3 and the connecting cover assembly 5 is increased, further enhancing the sealing performance.

[0035] Lower connecting plates 10 are fixedly installed around the top of the cylinder body 1. A connecting stud 11 is fixedly installed on the top surface of the lower connecting plate 10. A locking nut 12 is threaded onto the surface of the connecting stud 11.

[0036] By setting the upper connecting piece 10, tightening the locking nut 12 connects and fixes the upper connecting piece 10 and the lower connecting piece 13 together.

[0037] The cylinder head 6 has upper connecting pieces 13 fixedly installed around its bottom surface. The top surface of the upper connecting pieces 13 has a hole for easy insertion of the connecting studs 11.

[0038] The design of the socket facilitates the passage of the connecting stud 11.

[0039] In this invention, the working steps of the device are as follows:

[0040] First step: Insert the connecting cover assembly 5 into the insertion channel 2. The main cover 501 and the sealing strip 502 increase the contact area with the silicone sealing gasket 3, forming multiple sealing lines. Even if there is a partial failure, there is still a redundant sealing path, resulting in a good sealing effect. The titanium alloy memory spring sheet 4 increases the contact pressure between the silicone sealing gasket 3 and the connecting cover assembly 5, further enhancing the sealing performance.

[0041] The second step: When connecting the cylinder head 6 to the cylinder body 1, the outer sealing frame 7 is inserted into the outer sealing channel 9. The stainless steel gasket 801 and the graphite gasket 802 seal the bottom surface of the contact area between the outer sealing frame 7 and the outer sealing channel 9. Together with the silicone sealing gasket 3, a double seal is formed inside and outside, which makes the sealing effect between the cylinder head 6 and the cylinder body 1 better.

[0042] Third step: When connecting the cylinder head 6 to the cylinder body 1, the upper connecting piece 13 and the lower connecting piece 10 are in contact, the connecting stud 11 passes through the upper connecting piece 13, and the locking nut 12 is turned to fix the cylinder head 6 and the cylinder body 1 to each other.
