Embodiment Construction

[0013] As shown in the figure, a rotary non-follow-up angle valve is mainly composed of a valve body 2, an inner valve stem 3 and a push-pull screw 4. The valve body 2 is a sleeve type structure, and the inner valve stem 3 is fixed by the valve stem. The seat 6 is fixed in the valve body 2. One end of the inner valve stem 3 is connected to the sealing valve plate 1, and the other end of the inner valve stem 3 is connected to the push-pull screw 4 to form a screw sleeve type non-follow-up opening structure, rocker 5 Pass through the screw fixing seat 9 to connect with the push-pull screw 4, a convenient unloading joint 7 is arranged at the bottom of the valve body 2, and a sealing ring 8 is arranged on the surface of the sealing valve plate 1.

[0014] The working principle of the invention: the angle valve adopts metal direct pressure seal and is inlaid with a unique sealing structure. It has the characteristics of high temperature resistance and has been opened, which avoids the ...

Abstract

The unscrew non-follow-up angle valve is mainly composed of a valve body, an inner valve stem and a push-pull screw. The other end of the inner valve rod is connected with the push-pull screw to form a screw sleeve type non-follow-up opening structure. A rocker passes through the screw fixing seat to connect with the push-pull screw. A discharge valve is set at the bottom of the valve body. Easy connector. Aiming at the loading and unloading of high-temperature and high-viscosity chemical products, the invention adopts a novel and unique lead screw sleeve-type non-follow-up opening design, which has a large opening diameter, and the valve body filling rate is much better than conventional products. It has good sealing performance, high temperature resistance, and easy Advantages of opening and aesthetically compact.

Description

Technical field [0001] The invention relates to a valve, in particular to a screw-open non-follow-up angle valve used for loading and unloading high-temperature and high-viscosity materials on tank vehicles. Background technique [0002] With the continuous advancement of science and technology, the rapid development of the chemical industry has brought diversity in the transportation of chemical products. Due to the advantages of tank-type special-purpose vehicle transportation semi-trailers, it has become the leader in the conventional liquid chemical product transportation market. It has the huge advantages of safety, efficiency and convenience. [0003] With the advancement of chemical refining technology using petroleum, coal and other energy sources as raw materials, a large number of new chemical products have been continuously derived, and the diversity of physical properties of chemical products has also been continuously improved. Among them, chemical products with high v...
