Problems solved by technology

[0002] The ball valve is one of the common valves. Its opening and closing part is a sphere, and the flow is opened in the sphere. The valve stem drives the sphere to rotate, and the flow channel of the sphere is connected or disconnected from the flow of the front and rear valve seats to realize the valve opening and closing. The flow path of the traditional ball valve ball and the flow paths of the front and rear valve seats are all circular flow paths. The flow rate of the medium is very fast at the moment the valve is opened, and the erosion of the ball port is very serious, which is easy to cause damage to the ball, thereby causing damage to the valve. Shorten the service life of the valve and increase the cost of daily maintenance

Abstract

The invention relates to a high-temperature hexagonal hole wear-resisting ball valve. The high-temperature hexagonal hole wear-resisting ball valve comprises a valve body, a valve deck, a ball body and a valve rod, the ball body is arranged in an inner cavity of the valve body, the valve deck is fixed on the front side of the inner cavity of the valve body, the valve rod is connected with the upper end of the ball body, a front valve seat and a rear valve seat are arranged on positions, located on the front side and the rear side of the ball body, of the inner cavity, the rear valve seat is pressed tightly and fixed in the valve body through a valve seat pressing ring, the valve seat pressing ring is fixed in the valve body through a bolt, the front valve seat is arranged in the valve deckin a penetrating manner, a belleville spring set which enables the front valve seat to press tightly the ball body is arranged between the valve deck and the front valve seat, hexagonal hole runnersare formed in the ball body, the hexagonal hole runners are formed in the front valve seat and the rear valve seat which are matched, a valve rod bearing is installed between the valve rod and the valve body in a sealing manner, the upper end of the valve rod extends to the outer side of the valve body and is connected with a driving sleeve in a key manner, the driving sleeve is rotationally connected with a bracket, and the bracket is fixed on the upper end of the valve body. According to the high-temperature hexagonal hole wear-resisting ball valve, the flow area at the moment of opening isincreased, the medium flow speed is reduced, the scouring resistance of the ball body is improved, the service life of the valve is prolonged, and the daily maintenance cost is reduced.

Description

technical field [0001] The invention relates to a ball valve, in particular to a high-temperature wear-resistant ball valve with hexagonal holes. Background technique [0002] The ball valve is one of the common valves. Its opening and closing part is a sphere, and the flow is opened in the sphere. The valve stem drives the sphere to rotate, and the flow channel of the sphere is connected or disconnected from the flow of the front and rear valve seats to realize the valve opening and closing. The flow path of the traditional ball valve ball and the flow paths of the front and rear valve seats are all circular flow paths. The flow rate of the medium is very fast at the moment the valve is opened, and the erosion of the ball port is very serious, which is easy to cause damage to the ball, thereby causing damage to the valve. Shorten the service life of the valve and increase the cost of daily maintenance. Contents of the invention [0003] In view of the above shortcomings,...
