Abstract
The utility model relates to a fluid level control valve, belonging to a lifting valve that a floating ball drives a valve rod to act. The utility model has dual-cavity structure, the valve rod with a valve flap vertically passes through a valve cavity, and the floating ball is arranged at the lower end of the valve rod. The fluid level control valve can solve the problems of the existing water level control valve that the valve flap is easy to wear out, the valve is closed loosely, the floating ball and the valve rod are easy to fall, etc. The fluid level control valve has the advantages of compact structure, low cost, small size, good sealing effect, long service life, wide ranges of application, etc.
Description
The utility model belongs to a kind of poppet valve by ball float actuate valve stem action, valve body that it comprises a bivalve seat and the ball float that just is connected with valve rod.
Known heavy pull-type altitude valve and float valve are by valve body basically, formations such as lever, ball float, and the lifting driving ball float action by water level makes it to drive leverage and opens and closes control valve, realizes the automatic control and the automatic water inlet of cistern water level.But this class valve is the unlatching that the deadweight by ball float comes control valve, and flap is worn and torn easily, causes tight, the phenomenon such as leak of valve closing, and when water tank did not have water in addition, ball float was sagging, made ball float break away from lever easily, reduced working life.
The purpose of this utility model is to provide a kind of compact structure, good sealing effect, long service life, broad-spectrum high water tank control valve.
The utility model is made up of ball float, valve body, valve seat, valve rod, and its valve body is the dual chamber structure, and is provided with four desk fans in the epicoele, the valve rod of flap vertically passes valve pocket, and hollow float is installed in its valve rod lower end, when water tank does not have water, action of gravity owing to ball float and valve rod is lifted off a seat flap, and is located by the shoulder of valve body epicoele, valve open, to the water tank water filling, after the water tank fills with water,, buoyancy of water rises because driving ball float, the drive valve rod rises, and makes flap and valve seat closure.
Advantage of the present utility model is compact structure, and parts are less in addition, and volume is little, and is easy to process, cheap, valve opening is easily closed, and the power of closing is less, and its ball float is less, good sealing effect is difficult for leaking, and increases the service life applied range.
Accompanying drawing is the fluid level control valve schematic representation.
Implementation example: as shown in drawings, be provided with four shoulders in the upward pressure chamber in the two-chamber valve body 2 that forms by spheroidal graphite cast iron casting, valve rod 10 is a multidiameter shaft, flap 9 is packed in flap 9 and seal washer 8 on the valve rod 10 with lining 3 and 7 for having the annulus of breach, and is tight with nut 5 back ofs the body, the lower end car of valve rod 10 has screw thread, ball float 1 is housed, the water inlet end of valve body 2 respectively car screw thread is arranged, nut 4 and upper press cover 6 are housed.
Its valve body also can adopt cast iron, cast copper, nylon, plastic or other material to make in the utility model.
Claims (2)
1, fluid level control valve is by ball float, two-chamber valve body, valve seat, and valve rod is formed, and it is characterized in that being provided with in the uuper valve chamber four shoulders, and valve rod vertically passes valve pocket, and flap is housed on the valve rod, and hollow float is equipped with in the lower end.
2, according to claims 1 described fluid level control valve, it is characterized in that being equipped with on the valve rod two flaps, the valve seat with the valve body upper and lower cavity matches respectively.
