Description
The invention relates to the technical field of steam traps, in particular to a two-stage lever steam trap.
Background
The steam trap (simply called trap) is used for automatically removing non-condensable gases such as steam condensate and air in heating equipment or a steam pipeline, and steam is not leaked. Because the drain valve has the function of steam blocking and draining, the steam heating equipment can evenly supply heat, the latent heat of steam is fully utilized, and the occurrence of water hammer in the steam pipeline is prevented. Steam traps are widely used in setting machine equipment in printing and dyeing mills.
The existing steam trap commonly used in the market is a lever floating ball type steam trap, the lever floating ball type steam trap utilizes the lever principle, one fulcrum is arranged in the middle, one end is pressure generated by different pressures inside and outside a water outlet hole, and the other end is buoyancy generated by a floating ball in condensed water. The valve can be opened and closed as long as the following formula is satisfied: the pressure at the water outlet hole is multiplied by the length from one end of the lever to the fulcrum (the buoyancy of the floating ball-the gravity of the floating ball) and the length from the other end of the lever to the fulcrum. From the above formula we can see that for the formula to hold, the buoyancy of the float must be greater than the weight of the float. This limits the unrestricted increase in wall thickness of the float.
Therefore, the floating ball wall of the single-lever steam trap in the market is thinner, the floating ball is lighter, and the floating ball can be subjected to water pressure change after long-time use. Because the floating ball is lighter, the water outlet hole is difficult to firmly prop up through the lever, and the water pressure is often propped up, so that the valve is leaked.
