Abstract
The utility model relates to a floating ball valve, belonging to the technical field of hot water heating. The floating ball valve comprises a valve body, a valve core, a valve rod, a lever, a floating ball and a sealing ring. The floating ball valve is characterized in that the floating ball valve is provided with a valve body lining connected with the inner part of the valve body through a screw thread, a movable water passing ceramic chip and a static water passing ceramic chip. The valve core is arranged in the valve body lining. The static water passing ceramic chip is fixed on the valve body lining. The movable water passing ceramic chip is fixed on the valve core. The floating ball floats from top to bottom, which drives the valve core and the movable water passing ceramic chip to rotate, and the valve is controlled to be opened and closed. The utility model has the advantages of good sealing performance, and high durability.
Description
The utility model relates to the float valve that the water tank control water level is used, and belongs to the hot-water heating equipment technical field.
At present, the float valve that water tank is used is pusher float valve, and spool is the axial motion form.Mainly be made of valve body, spool, valve rod, lever, sealing gasket, ball float etc., sealing gasket is arranged on the top of spool, by the axial forward and back of spool, and the closing and opening of the water passage hole of control valve body.Whether the sealing of this float valve is mainly tight by the sealing between sealing gasket and the water passage hole, because rubber gasket is easily aging, particularly is subjected to the influence of high temperature, and easier generation is aging, causes poorly sealedly, forms leakage phenomenon.
The purpose of this utility model be to provide a kind of keying of radially rotating control valve by spool, good airproof performance, the float valve of long service life.
The purpose of this utility model is to realize by the improvement to existing float valve, float valve, comprise valve body, spool, valve rod, lever, ball float, seal ring, it is characterized in that float valve is provided with valve body lining and the dynamic and static ceramic water sheet of crossing of bringing osculum on the wall into, the valve body lining is threaded and is fixed in the valve body, spool is arranged in the valve body lining, the spool top was provided with ceramic water sheet and seal ring, moving the ceramic water sheet is plugged on the spool, the quiet ceramic water sheet of crossing is fixed on the valve body lining, and seal ring is fixed on the water passage hole and the quiet water of crossing of valve body and makes pottery between the comfortable sheet.Ball float just moves up and down with the water level in the water tank, and the ceramic water sheet that moved that drives spool and spool top rotates, and controls opening and closing of float valve.Said sound is crossed the ceramic water sheet, and for ceramic plate is provided with water passage hole, road, two ceramic plates relatively rotate several angle, reaches the perforation and the partition in water passage hole, road.
The utility model novel structure, reasonable, simple is manufactured easily, and ceramic plate is wear-resisting, and is durable in use, and seal ring is a fixed block, and is not fragile, and good airproof performance is the desirable Updated product of float valve.
Accompanying drawing 1 is the structural representation of valve body part of the present utility model, and 1 valve body, 2 spools, 3 valve bodies lining, 4 moved ceramic water sheet, 5 quiet ceramic water sheet, 6 seal rings, 7 valve rods, 8 rubber rings, 9 rubber rings, 10 nuts crossed among the figure.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
The valve body lining is set in valve body, and the valve body lining is established paddle hole for tubulose on the wall, and the valve body lining is threaded with valve body.Spool is arranged in the valve body lining, and the top of spool is provided with boss, moved on the ceramic water sheet groove is set, and the groove that moved the ceramic water sheet is inserted on the boss on spool top.On the valve body lining inwall axial notch is set, on the quiet outer wall of crossing the ceramic water sheet protruding stalk is set, the quiet protruding ridge of crossing on the ceramic water sheet is inserted in the groove on the valve body lining inwall.Seal ring is arranged on the water passage hole and quiet the mistake between the ceramic water sheet of valve body, and seal ring is inserted in the valve body lining.Between valve body and the valve body lining, spool is provided with rubber seal respectively between serving as a contrast with valve body.On valve rod, connect lever, ball float.For reducing the length of lever, at the middle part of lever one heavy ball can be set, ball float falls rapidly when guaranteeing in the water tank drawdown.
