Problems solved by technology

[0003] The traditional bonnet is not equipped with positioning pins. When it is installed and fixed, it is fixed on the valve by manual rotation. There is no positioning and fixing of the locating pins. Sometimes it is easy to cause the bonnet to be misplaced during installation and the installation is not tight. It is solid, which brings safety hazards, and the traditional bonnet is not equipped with heat dissipation fins, so that the bonnet does not have any heat dissipation function, and the applicable temperature of the bonnet is not high, which limits the working range of the bonnet

Abstract

The invention discloses a bonnet with positioning hinge pins. The bonnet with the positioning hinge pins comprises a bonnet body, a bonnet bottom support and a high-strength supporting column, whereina positioning hole a and a positioning hole b are separately formed in the top surface of the bonnet body; a positioning hinge pin a and a positioning hinge pin b are separately mounted in the positioning hole a; a connecting shaft is mounted at the bottom end of the bonnet body; the bonnet bottom support is mounted on the bottom of the connecting shaft through a connecting buckle; a round grooveis formed in the position of the center of circle of the bonnet body; an uncovering tooth groove is formed in the round groove; and the high-intensity supporting column is mounted in the connecting shaft. The positioning hinge pins are mounted in the bonnet, the bonnet can be positioned through the positioning hinge pins, the bonnet is fixed by tightening the positioning hinge pins, position accuracy of mounting of the bonnet is ensured, and furthermore, stability of mounting of the bonnet is also ensured.

Description

Technical field [0001] The invention belongs to the technical field of valve cover devices, and particularly relates to a valve cover provided with a positioning pin shaft. Background technique [0002] The bonnet is one of the main parts of the regulating valve, mainly related to the pressure-bearing, corrosion resistance, external leakage and sealing of the regulating valve and adapting to different working media and working temperatures. [0003] The traditional bonnet is not equipped with a positioning pin. When it is installed and fixed, it is fixed on the valve by manual rotation, and there is no positioning and fixing of the positioning pin. Sometimes it is easy to cause the valve cover to be installed incorrectly and not tightly installed. The valve cover does not have any heat dissipation function, and the applicable temperature of the valve cover is not high, which limits the working range of the valve cover. Summary of the invention [0004] The object of the present inv...
