Description

Rigid density high temperature ball valve for easy installation

technical field

The utility model relates to the technical field of valves, in particular to a hard density high temperature ball valve which is easy to install.

Background technique

At present, with the massive construction of industrial facilities, more and more valves are used, and there are more and more types of valves with more and more functions. Among them, the use of hard-sealed high-temperature ball valves is also increasing. As a component used to realize on-off and flow control of pipeline systems, it has been widely used in many fields such as petroleum, chemical industry, metallurgy, and hydropower. In the hard-sealed high-temperature ball valve, the ball and the valve seat are tightly matched. After long-term use, the valve body parts are prone to offset, resulting in misalignment of the ball and the valve seat, resulting in internal leakage; at the same time, the valve stem is fixed on the bracket during installation. However, the installation of the bracket is troublesome. At present, screws are generally used for fixing, and the screws are not easy to align with the screw holes during installation.

Utility model content

The utility model aims to solve the above-mentioned problems in the prior art, and provides an easy-to-install hard-density high-temperature ball valve, which is easy to install and has a reasonable structural design.

The technical solution adopted by the utility model to solve its technical problems: this easy-to-install hard-density high-temperature ball valve includes a middle body and side bodies installed on the left and right sides of the middle body. A ball is installed in the side body, and the ball is connected to the valve stem. Installed on the bracket, the outer side of the middle body is provided with a card slot, and the side body is provided with a raised part that is stuck in the card slot; the bottom of the middle body is equipped with a support block, which penetrates into the middle body and is supported on the sphere At the bottom, the support blocks are bolted to the midbody. In this structure, the cooperation between the middle body and the side body is more firm. Through the cooperation between the card slot and the raised part, the side body is prevented from shifting. Fit between ball and seat.

For further improvement, a limit installation part is provided on the outside of the support block, and an installation groove for the limit installation part to be embedded is provided at the bottom of the middle body. In this way, the support block is more firmly fixed on the middle body, and the mounting groove can prevent the support block from shifting.

As a further improvement, a matching slot and block structure is provided between the top surface of the limit installation part and the installation groove. This makes the installation of the support block and the middle body more firm.

Further improvement, the bracket includes an upper bracket and a lower bracket, the lower bracket is fixed on the middle body, one side of the lower bracket is positioned on the middle body by positioning pins, the other side of the lower bracket is fixed on the middle body by screws, and the upper bracket is fixed by bolts On the lower support, a worm gear is fixed on the upper support. The installation is more convenient and easy like this. Firstly, one side of the lower bracket is positioned by positioning pins, and then the other side of the lower bracket is fixed by screws.

The beneficial effects of the utility model are: the utility model installs and connects the middle body and the side body more firmly, the support block on the middle body is supported on the sphere, prevents the position of the sphere from shifting, and makes the gap between the sphere and the valve seat long-term sealing fit,
