Abstract

The utility model belongs to an automatic valve of a small hardware class, comprising components of a rectangular valve base (1), a valve core (3), a pressing spring (5), a valve core block (6), a lever (7) and a float ball (8), etc. The principle of the utility model is that the float ball which is arranged on both ends of the lever on a head end of the valve core causes the valve to open and close on the function of a liquid material flotage. The utility model has the advantages of simple structure, easy manufacture, and good liquid level control effect. The utility model is suitable for the valve installation for various liquid material storage tanks.

Description

Auto-valve

The utility model belongs to the hardware class.

At present, the valve that is used for liquid storage pool mostly is manual or automatically controlled, if meet hermetic pot for storing up liquid accumulation liquid except adopting electric control valve, adopting manually-operated gate is to be difficult to the control liquid level, adopts electric control valve can cause fire or blast if the liquid material is a combustible material.

The purpose of this utility model is to overcome the problem that above-mentioned two kinds of valves in use exist and designs.

The utility model is to adopt the principle of mechanical lever and the floating function of liquid material to make valve opening and closing, and its composition is to float parts such as ball to constitute by the Different Weight that is located at spool and the spool lever in the valve seat and is located at two ends.Its function be when the channel flow of liquid material from valve seat out-of-date, the relative liquid material that makes with pipe diameter in spool pore aperture that is located on the center spool passes through, at this moment lever at one end quality big float under the ball action of gravity to quality big float direction of bowl inclination 45, i.e. the state that is out of valve.When liquid storage pool or jar in when holding full liquid material because the liquid level of liquid material rises, float ball and under the floating function of liquid material, lever be the level of state, the spool pore turns to 45 ° to avoid the valve seat pipeline opening, valve is the state of closing.Following drawings attached describes structure of the present utility model.

Fig. 1 is a structure cut-away view of the present utility model.

1 is the foundry goods valve seat among Fig. 1, its outward appearance is rectangular, its inside is the duct 2 that two decussate through hole pipelines 2 and installing spool are used "; the duct is the through hole that is taper type; it is cylindrical being provided with head end in the duct; tail end is the spool 3 of taper type and middle band through hole; the through hole in the middle of the spool 3 is a spool pore 4; then be provided with stage clip 5 and spool stifled 6 in the duct, rear portion of spool 3, the part of extending outside valve seat 1 at the head end of spool 3 is provided with the lever 7 with spool pore 4 angles at 45, the two ends of lever 7 be provided with the band strut and vary in weight float ball 8.

Fig. 2 is a user mode cut-away view of the present utility model.Lever 7 states shown in Fig. 2 are level, spool pore 4 is 45 with lever 7 and pipe hole 2, and this state is to make the ball 8 that floats that is located at lever 7 two ends be up to the standard and form under the floating function of liquid material because the liquid material in the liquid storage pool is filled with the rising of liquid level afterwards.Its state is the valve closing state.

The utility model is a kind of autocontrol valve of machinery, its advantage be need not be manually or electric energy monitor the situation of filling with of liquid material, can be according to the keying of the lifting situation by-pass valve control of liquid level, the utility model also has simple in structure, be easy to the advantage of fabrication and installation, applied range.

Claims (2)

1, a kind of automatic valve is by valve seat 1, spool 3, stage clip 5, spool is stifled 6, lever 7 and float ball 8 and constitute, and it is characterized in that: valve seat 1 is rectangular, is provided with the pipe hole 2 of two intersections and the duct 2 that the installing spool is used in valve seat 1, in duct 2, be provided with spool 3, stage clip 5, spool stifled 6.

2, automatic valve according to claim 1, it is characterized in that: spool 3 its head ends that are located in valve seat 1 duct 2 are cylindrical, tail end is a taper type, rear-end neutrality line is provided with spool pore 4, the head end of spool 3 leans out a wall and the part that leans out is provided with lever 7 with spool pore 4 angles at 45, the two ends of lever be two band struts that vary in weight float ball 8.
