Abstract

The invention provides a high temperature resistant combined valve connecting device, which mainly includes a valve head, a valve stem, a spring seat, a spring, a valve cover and a snap ring, the valve head is installed at the lower end of the valve stem, and the spring seat is installed at the upper end of the valve stem, and The lower end of the spring seat is equipped with a spring and is connected with the valve seat, and the valve stem is equipped with a valve cover, and the valve cover is fixed by a snap ring welded on the valve seat. Its characteristic is that the valve head is resistant to high temperature and can be replaced. The invention realizes the high temperature resistance of the valve and the replaceability of the valve head through the ceramic material and the valve head provided with the external thread cylindrical head; through the valve stem made of constant steel material and containing the upper and lower blind holes, the low expansion of the valve stem is realized , low quality and ensure the working accuracy of the valve; the rapid heat dissipation of the valve is realized through the valve cover of aluminum alloy material; the expansion and deformation of the valve cover is restrained by the snap ring made of constant steel material.

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...
