Abstract

The utility model discloses a float valve, particularly relates to a float valve with a thread ball valve as a main unit, and belongs to the technical field of float valves. The float valve comprises a seal gasket, a valve stem, a connecting rod, a float ball, a valve body, a hole and a ball, and is characterized in that both ends of the valve body are provided with threads, the seal gasket and the ball are arranged in the valve body, the hole is reserved on the ball, the ball is connected with the valve stem, and the connecting rod is arranged between the valve stem and the float ball and is perpendicular to the axis of the hole. During use of the float valve, the float valve is mounted on an orifice of a liquid outlet pipe along a liquid inlet direction of the valve body, is turned on and off automatically along with lifting and falling of the float ball, and has the advantages of large pipe diameter, compact structure, good sealability and reliability and high practicability.

Description

A kind of float valve

Technical field

The utility model relates to a kind of float valve, relates in particular to that a kind of the screw thread ball valve is arranged is the float valve of main body, belongs to the float valve technical field.

Background technique

Float valve is regulated liquid supply rate through the control liquid level, cursory all to float on all the time waterborne, when the water surface goes up, cursory also and then rising; Float rising and also rise with regard to drivening rod, connecting rod links to each other with the valve of the other end, and when rising to certain position, connecting rod is propped the rubber piston pad; The sealing water source, when drawdown, cursory also decline, connecting rod drives piston pad again and opens; Present float valve exists the keying latus rectum little, the shortcoming that liquid outlet quantity is little, and in actual use, the fire water tank of tall building is being used water state; Because the latus rectum of float valve is little, fluid infusion velocity is far smaller than operating speed, causes and sees water, and water tank uses up the danger that can not put out a fire; The characteristics of existing ball valve are that latus rectum is big, and fluid resistance is little, and the ball valve in all-pass footpath does not have flow resistance basically; Before the utility model was not made, not having had that a kind of the screw thread ball valve is arranged is that the float valve of main body uses, and it is open that the patent searching document does not have the new technological scheme of this technology.

Summary of the invention

Have in order to overcome in the existing technology not have that a kind of the screw thread ball valve is arranged is that the float valve of main body is not enough; The purpose of the utility model is that a kind of the screw thread ball valve is arranged is the float valve of main body in order to provide; This floating ball valve structure is compact, and sealing is reliable, and is simple in structure; Purpose easy to maintenance, as to be widely used in every profession and trade.

The technological scheme that its technical problem of the utility model solution is taked is: be made up of sealing gasket, valve rod, connecting rod, ball float, valve body, hole, spheroid, it is characterized in that there is screw thread at two of valve body, sealing gasket and spheroid are arranged in the valve body; Hole is arranged on the spheroid, and spheroid is connected with valve rod, between valve rod and the ball float connecting rod is arranged; The axis of connecting rod and hole becomes 90 degree, during use the utility model valve body feed liquor direction is installed in the mouth of pipe of drain pipe, and valve rod is parallel with liquid level; When ball float dropped to the liquid level that is lower than designing requirement, the ball float drivening rod descended, and connecting rod drives valve rod and makes the spheroid rotation; The sphere of spheroid and sealing gasket dislocation, the hole on the spheroid forms path with the valve body both sides, and liquid promptly flows out from the liquid outlet of valve body; When liquid made ball float rise to the liquid level of design, the ball float drivening rod rose, and connecting rod drives valve rod and makes the spheroid rotation; The sphere and the sealing gasket of spheroid revert to closed position, and the hole on the spheroid can not make the valve body both sides form path, and liquid is promptly by choked flow.

The beneficial effect of the utility model is a compact structure, and sealing is reliable, and simple in structure, easy to maintenance, practicability is bigger.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the schematic representation of the utility model.

1. sealing gaskets among Fig. 1,2. valve rod, 3. connecting rod, 4. ball float, 5. valve body, 6. hole, 7. spheroid.

Embodiment

The utility model is made up of sealing gasket 1, valve rod 2, connecting rod 3, ball float 4, valve body 5, hole 6, spheroid 7, and there is screw thread at its two that it is characterized in that valve body 5, and sealing gasket 1 and spheroid 7 are arranged in the valve body 5; Hole 6 is arranged on the spheroid 7, and spheroid 7 is connected with valve rod 2, between valve rod 2 and the ball float 4 connecting rod 3 is arranged; The axis of connecting rod 3 and hole 6 becomes 90 degree, during use the utility model valve body 5 feed liquor directions is installed in the mouth of pipe of drain pipe, and valve rod 2 is parallel with liquid level; When ball float 4 dropped to the liquid level that is lower than designing requirement, ball float 4 drivening rods 3 descended, and connecting rod 3 drives valve rod 2 and makes spheroid 7 rotations; The sphere of spheroid 7 and sealing gasket 1 dislocation, the hole 6 on the spheroid 7 forms path with valve body 5 both sides, and liquid promptly flows out from the liquid outlet of valve body 5; When liquid made ball float 4 rise to the liquid level of design, ball float 4 drivening rods 3 rose, and connecting rod 3 drives valve rod 2 and makes spheroid 7 rotations; The sphere of spheroid 7 and sealing gasket 1 revert to closed position, and the hole 6 on the spheroid 7 can not make valve body 5 both sides form path, and liquid is promptly by choked flow.

Claims

1. float valve, it is made up of sealing gasket (1), valve rod (2), connecting rod (3), ball float (4), valve body (5), hole (6), spheroid (7), it is characterized in that; There is screw thread at two of valve body (5); Sealing gasket (1) and spheroid (7) are arranged in the valve body (5), hole (6) is arranged on the spheroid (7), spheroid (7) is connected with valve rod (2); Between valve rod (2) and the ball float (4) connecting rod (3) is arranged, the axis of connecting rod (3) and hole (6) becomes 90 degree.
