Abstract

The utility model relates to the technical field of a floating-ball valve, in particular to a straight-through floating-ball valve which comprises a valve cover, a valve body, a valve rod, a valve plug and a ball chamber, and is characterized in that the valve body at the upper part of a flow channel hole is provided with a piston hole, and the valve body at the upper part of the piston hole is provided with the valve cover; the valve body at the lower part of a flow channel hole is provided with a vertical limiting groove corresponding to the position of the piston hole; the bottom of the limiting groove is provided with an axle hole; after the valve rod sequentially passes through the axle hole and the limiting groove, the top of the valve rod is connected with the metal valve plug; the bottom of the valve rod is positioned inside the ball chamber and is connected with a floating ball; a valve rod outer cover between the metal valve plug and the limiting groove is provided with a spring; the metal valve plug is externally covered with a sealing layer; and filler is arranged between the valve rod and the valve body. Compared with the prior art, the elastic function of the external spring is used for automatically compensating the working height, so that the whole floating-ball valve can freely move under the condition of stable work.

Description

The straight-through type float valve
[technical field]
The utility model relates to the float valve technical field, specifically a kind of straight-through type float valve.
[background technique]
Float valve is the variation by ball indoor liquid liquid level, drives ball float and moves up and down.Because the particularity of Environmental Conditions, the effect of its valve rod is outstanding especially, and particularly the scalability of valve rod directly causes the range that uses.Common float valve mostly is single lever-type, horizontal dress rod-type, linkage type, its complex structure, huge, and fluctuation of service.
[summary of the invention]
The purpose of this utility model is to overcome the deficiencies in the prior art, with connecting the nut of the stem bottom that spool uses, replaces with the structure with the valve rod integral type.Sheathed spring outside the valve rod between metal valve plug and restraining groove has directly solved the difficulty of valve rod operation.
For achieving the above object, the utility model designs a kind of straight-through type float valve, comprise valve gap, valve body, valve rod, valve plug, ball chamber, it is characterized in that: on the valve body on runner mouth top, establish a piston hole, establish a valve gap on the valve body on piston hole top, a vertical restraining groove is established in corresponding piston hole position on the valve body of runner mouth bottom, the restraining groove bottom is an axis hole, the metal valve plug was established in top connection one after valve rod passed axis hole, restraining groove successively, stem bottom is positioned at the indoor connection ball float of ball, sheathed spring outside the valve rod between metal valve plug and restraining groove; Described metal valve covers sealing layer beyond the Great Wall; Be provided with filler between described valve rod and the valve body.
The utility model is compared with prior art, utilizes the automatic compensation work height of elastic reaction of external spring, remains under the stable situation and works, and makes whole float valve motion freely.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Referring to Fig. 1,1 is ball float, and 2 is valve body, and 3 is filler, and 4 is valve rod, and 5 is valve gap, and 6 is the metal valve plug, and 7 is spring, and 8 is restraining groove, and 9 is sealing layer.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, on the valve body 2 on runner mouth top, establish a piston hole, establish a valve gap 5 on the valve body 2 on piston hole top, a vertical restraining groove 8 is established in corresponding piston hole position on the valve body 2 of runner mouth bottom, and restraining groove 8 bottoms are axis hole, and valve rod 4 passes axis hole successively, metal valve plug 6 is established in top connection one behind the restraining groove, valve rod 4 bottoms are positioned at the indoor connection ball float 1 of ball, sheathed spring 7 outside the valve rod 4 between metal valve plug 6 and restraining groove, behind spring stress, displacement of valve rod, direction of displacement upwards, this moment direct actuator, otherwise, after spring is stressed, the push rod displacement is downward, valve rod tightens, and reaction this moment float valve drives float valve to test.Metal valve covers sealing layer 9 beyond the Great Wall.Be provided with filler 3 between valve rod 4 and the valve body 2, sealing layer 9 and filler 3 can make valve rod 4 avoid wearing and tearing in movement process, and make between valve rod and the valve body and closely cooperate, and reach and do not leak, and valve rod has good airproof performance not by the purpose of locking simultaneously.
