Abstract

The invention relates to a drain valve and provides a guild rail type free float drain valve which uses a three-point positioning sealing mode. The valve comprises a valve body, a valve cover, an air exhaust device, a filtering screen, a separating cover, a snap spring, a floating ball, a sewage draining bolt, a guild rail, a main valve seat, a main valve seat gasket and an outer plug, wherein the valve cover is installed at the upper end of the valve body, a wound gasket is arranged between the valve body and the valve cover, the air exhaust device is connected with a threaded hole of the lower end face of the valve cover, the floating ball is arranged in the inner cavity of the valve body, the separating cover and the filtering screen are respectively installed on a boss of the inner cavity of the valve body, the snap spring is pressed on the filtering screen and is arranged in a groove of the snap spring, the sewage draining bolt is sleeved in the wound gasket and is installed in a sewage draining threaded hole of the side lower end of the valve body, the guild rail is arranged on the two side surfaces of the bottom of a valve cavity and is connected with the valve body into a whole, an axle center of the guild rail and a main valve seat hole are coaxial, the cambered surface of the guild rail is the same as the radian of the outer diameter of the floating ball, the main valve seat is sleeved in the main valve seat gasket and is connected with the main valve seat threaded hole of the valve body, and the outer plug is sleeved in the wound gasket and is in threaded connection with the lower side end of the valve body.

Description

technical field [0001] The invention relates to a high-precision steam trap, in particular to a guide rail type free-floating ball steam trap. Background technique [0002] Existing steam traps include steam traps and air traps, and steam traps include mechanical, thermostatic, and thermodynamic types. Most air traps are mechanical. Mechanical traps include free float traps, lever float traps, inverted bucket traps, etc. The mechanical trap is developed by using the principle of density difference between steam and condensed water or steam (gas) and liquid. Since the density of steam (gas) and liquid is very different, the buoyancy is also different. Using this feature, Make the float play a role, so as to open and close the valve, and achieve the function of blocking steam (gas) and draining water. Compared with lever float traps and inverted bucket traps, free float traps have the advantage of not having a lever structure, which overcomes the problems of friction, easy ...
