[0026] A groove 12 is provided inside the head body 1 .

[0027] The sealing ring 7 is fixedly connected to the bottom of the connecting pipe 8 .

[0028] The reinforcing rib 2 and the head body 1 are connected by welding, and the head body 1 and the connecting flange 3 are connected by welding.

[0029] The head body 1, the reinforcing ribs 2, the connecting flange 3 and the pressure relief valve 11 are made of stainless steel.

[0030] The pressure relief valve 11 includes a connecting plate 111 , a valve seat 112 is fixedly connected to the bottom of the connecting plate 111 , a valve body 113 is fixedly connected to the bottom of the valve seat 112 , and a pressure relief pipe 114 is provided at the bottom of the valve body 113 .

[0031] The sealing ring is made of rubber or fluororubber.

[0032] In this embodiment, the head design includes a head body 1, on which a plurality of reinforcing ribs 2 are fixedly connected to enhance structural strength and stability, and can withstand higher pressure and temperature changes. A connecting flange 3 is fixedly connected to the upper part of the head body 1, and is provided with bolt holes 4, bolts 5 and gaskets 6 to ensure the tightness of the connection parts. The sealing rings 7 on the connecting flange and the connecting pipe enhance the sealing and improve safety and reliability. In addition, an inner lining layer 9 is provided inside the head body 1 to improve wear resistance, and an outer protective layer 10 is provided outside to enhance corrosion resistance. A pressure relief valve 11 is also provided at the bottom, which can automatically release pressure when the pressure is abnormal, reducing the risk of safety accidents. The design of this new head effectively extends the service life of the equipment, reduces maintenance costs, improves production efficiency, and better meets the needs of industrial production.

[0033] The sealing ring 7 is made of rubber or fluororubber, which has good elasticity and chemical corrosion resistance. One end of the sealing ring 7 fits tightly with the groove on the connecting flange 3, and the other end is fixedly connected to the bottom of the connecting pipe 8, ensuring a tight sealing interface between the two.

[0034] The reinforcing ribs 2 are distributed in an annular pattern on the outer surface of the head body 1 and are firmly connected to the head body 1 by welding, thereby increasing the rigidity and pressure resistance of the head body 1. The head body 1 and the connecting flange 3 are also connected by welding to ensure the stability and sealing of the connection between the two.

[0035] The pressure relief valve 11 is mounted on the bottom of the head body 1 and primarily consists of a connecting plate 111, a valve seat 112, a valve body 113, and a pressure relief pipe 114. The connecting plate 111 is bolted to the head body 1, with the valve seat 112 tightly connected to the connecting plate 111. The valve body 113 is mounted below the valve seat 112 and contains a spring and valve core. When the system pressure exceeds a preset value, the valve core is pushed open, releasing the excess pressure through the pressure relief pipe 114.

[0036] When in use, first, connect the head body 1 to the pipeline or other equipment components through the connecting flange 3 on its upper part, and use the multiple bolt holes 4 on the connecting flange 3 to tighten with the bolts 5 and gaskets 6. The sealing ring 7 on the connecting flange 3 and the connecting pipe 8 ensures that the connection is tight and leak-free. The protective layer 10 on the outside of the head body 1 and the lining layer 9 on the inside can effectively resist the erosion of high temperature, high pressure and corrosive media, improving the durability and stability of the head. When the internal pressure of the system exceeds the safe range, the pressure relief valve 11 at the bottom of the head will automatically start, quickly releasing the overpressure and ensuring the safe operation of the entire system. This not only significantly improves the performance of the equipment, but also effectively reduces maintenance costs.
