Problems solved by technology
Equipped with a natural gas ball valve flowmeter measurement system, it can manage the natural gas quantitatively, which is convenient for the unit to measure the energy for its own use. The ball valves in the natural gas ball valve flowmeter mostly use motors, speed change mechanisms and screw structures. Although they can control natural gas pipelines But there are the following problems: 1. The speed of opening and closing is slow, and it is generally used in medium and low pressure pipelines; 2. The manufacturing process is complicated and the cost is high; 3. The energy consumption is large; 4. It is difficult to open and close in high-pressure pipelines

Embodiment Construction
[0029] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0030] A ball valve structure based on cam control, including a valve cover 23, a valve body 1, and a valve core 17. A sealing rubber ring 12 is installed, and the sealing rubber ring cooperates with the valve core, and a camshaft 20 is rotated on the bonnet, and a camshaft sleeve 5 is installed between the camshaft and the bonnet, between the camshaft sleeve and the camshaft A sealing ring 13 is installed between them, a cam 10 is fixed at the lower end of the camshaft, and a shift fork 9 is fixed on the camshaft between the cam and the valve cover. In this embodiment, the shift fork passes through the positioning key 8 on the camshaft and The camshaft is fixed, and the upper part of the spool is coaxially fitted with the lower part of a sw...

The invention relates to a high-pressure gas ball valve based on cam control. The high-pressure gas ball valve comprises a valve deck, a valve body and a valve element. The valve deck is fixedly arranged on the valve body. The valve element is installed on a universal seat in the valve body. A camshaft is installed on the valve deck. A cam is fixedly arranged at the lower end of the camshaft. A shifting fork is fixedly arranged at the portion, between the cam and the valve deck, of the camshaft. The lower portion of a swing rod is coaxially sleeved with the upper portion of the valve element so that the valve element can swing. The swing rod is sleeved with a spring. A center groove matched with the cam is formed in the upper end face of the swing rod so that the swing rod can swing. A side groove matched with the shifting fork is formed in the circumference of the upper end face of the swing rod so that the swing rod can rotate. The high-pressure gas ball valve of a ball valve structure and based on cam control is simple in structure, scientific and reasonable in design, low in manufacturing cost, safe, reliable, accurate in action, convenient to control, small in energy consumption, good in sealing performance and capable of effectively achieving the high-pressure gas opening and closing function.
Description
[0001] This application is a divisional application for an invention patent titled cam-based control ball valve structure and ball valve, the patent application number is 201210176327.5, and the patent application date is 2012.05.31. technical field [0002] The invention belongs to the field of ball valves, in particular to a high-pressure gas ball valve based on cam control. Background technique [0003] Natural gas ball valve flowmeter is widely used in various fields of national economy such as metallurgy, electric power, chemical industry, textile, food, medicine, catering and people's daily life. It is mainly used to measure the flow of natural gas. Equipped with a natural gas ball valve flowmeter measurement system, it can manage the natural gas quantitatively, which is convenient for the unit to measure the energy for its own use. The ball valves in the natural gas ball valve flowmeter mostly use motors, speed change mechanisms and screw structures. Although they can ...
