Description

Technical Field

[0001] The utility model belongs to the technical field of spring valves and relates to a new spring valve. Background Art

[0002] The spring valve is a common control valve. Its working principle is to control the opening and closing of the valve by manual pressure. The hand-pressure spring valve is usually used in some small water pipes, gas pipes and other pipeline systems. It can be easily controlled manually, and the operation is simple and convenient. The structure of the hand-pressure valve is relatively simple, usually consisting of a valve body, a valve core, a spring, a handle and other parts. When the handle is pressed, the valve core will be compressed, so that the valve is closed; when the handle is released, the spring will bounce the valve core back to the desired position, and the valve will open. The opening and closing speed of the hand-pressure valve depends on the pressure of the handle and the elasticity of the spring. The contact between the valve stem and the handle can easily cause wear and tear on both, which can easily cause damage to the handle. Its replacement is relatively cumbersome, and the replacement cost is increased. At the same time, its function is single, so it cannot meet the use requirements. Summary of the invention
