Embodiment

[0015] Such as figure 1 As shown, a high temperature resistant combined valve connection device of the present invention mainly includes a valve head 1, a valve stem 3, a spring seat 8, a spring 6, a valve sleeve 4 and a snap ring 5, and the valve stem 3 is provided with a valve head 1 , the upper end of the valve stem 3 is equipped with a spring seat 8, and the lower end of the spring seat 8 is equipped with a spring 6 and is connected with the valve seat 2. fixed.

[0016] The valve head 1 is made of ceramic material, has a frustoconical structure and a cylindrical head with an external thread on the top, and the cylindrical head of the valve head 1 is installed in the lower blind hole of the valve stem 3 . When working, this design realizes the high temperature resistance of the valve and the replaceability of the valve head 1, that is, the use of the high temperature resistance, heat insulation, high hardness and wear resistance of ceramic materials can reduce the high te...

Abstract

The invention provides a high-temperature resisting combined valve connecting device. The high-temperature resisting combined valve connecting device mainly comprises a valve head, a valve rod, a spring base, springs, a valve sleeve and clamping rings. The valve head is arranged at the lower end of the valve rod. The spring base is arranged at the upper end of the valve rod. The springs are arranged at the lower end of the spring base, and the spring base is connected with the valve base. The valve sleeve is arranged outside the valve rod. The valve sleeve is fixed through the clamping rings welded to the valve base. The high-temperature resisting combined valve connecting device is characterized in that the valve head can resist to the high temperature and can be replaced. By means of ceramic materials and the valve head with an external thread cylinder head, the high-temperature resistance and the replaceable valve head of a valve are achieved. By means of invar steel materials and the valve rod with an upper blind hole and a lower blind hole, the low expansion and low mass of the valve rod are achieved, and the work precision of the valve is guaranteed. By means of the valve sleeve made of aluminum alloy materials, rapid heat dissipation of the valve is achieved. The expansion deformation of the valve sleeve is restrained through the clamping rings made of the invar steel materials.

Description

technical field [0001] The invention relates to a high temperature resistant combined valve connecting device, in particular to a valve head which is made of ceramic material and provided with a cylindrical head with external threads, so as to realize the high temperature resistance of the valve and the replaceability of the valve head; The valve stem with upper and lower blind holes realizes low expansion and low quality of the valve stem and ensures the working accuracy of the valve; the rapid heat dissipation of the valve is realized through the valve sleeve made of aluminum alloy material; the expansion of the valve sleeve is restrained through the clasp ring made of constant steel material Deformation belongs to the technical research and development field of engine valves. Background technique [0002] As an important part of the engine, the valve is responsible for inputting air into the engine and discharging exhaust gas after combustion. However, due to the singlen...
