Abstract

The invention relates to a three-sheet type manual ball valve, in particular to the three-sheet type manual ball valve used for disconnecting or connecting media in a pipeline, and belongs to the technical field of pipeline valves. The three-sheet type manual ball valve comprises a valve body and a valve ball, wherein the valve ball capable of rotating freely is arranged inside the valve body; valve decks are connected to the two ends of the valve body, and valve seats are arranged between the valve decks and the valve ball; a valve rod is connected to the upper end of the valve ball, the upper end of the valve rod extends out of the valve body, and a packing gland is arranged between the valve rod and the valve body; and the valve decks are provided with outer fluid through holes, and the valve ball is provided with an inner fluid channel. The three-sheet type manual ball valve is simple, compact and reasonable in structure, stable and reliable in work, good in sealing performance and convenient to maintain and can disconnect or connect the media in the pipeline, the effective drift diameter is greatly increased, and the fluid resistance is reduced.

Description

Three-chip type manual ball valve
Technical field
The present invention relates to a kind of three-chip type manual ball valve, is particularly used for blocking or connecting three of pipeline intermediary matter Formula manual ball valve, belongs to pipe valve technical field.
Background technology
It is general on the equipment or pipeline of conveying steam and air dielectric that valve is set, controlled by the opening and closing of valve The break-make of gas medium conveying.In prior art, conventional pipe valve effective drift diameter is less, easy shape after valve Long-Time Service Into obturation, normally using for pipeline is affected.
The content of the invention
It is an object of the invention to overcome above-mentioned weak point, so as to provide a kind of three-chip type manual ball valve, can block Or the medium connected in pipeline, effective drift diameter greatly improves, and fluid resistance diminishes, easy to maintenance.
According to the technical scheme that the present invention is provided, three-chip type manual ball valve includes valve body and valve ball, it is characterized in that:In valve body The valve ball that can freely rotate is provided with, valve body two ends connect respectively valve gap, and valve seat is provided between valve gap and valve ball;Valve ball upper end connects Valve rod is connect, valve body is stretched out in valve rod upper end, and gland is provided between valve rod and valve body;The valve gap is provided with outer fluid through hole, Valve ball is provided with fluid passage.
Further, valve rod upper end connection handle and valve stem nut, valve stem nut is fastened on handle on valve rod.
Further, valve gap, valve body and valve seat junction are provided with sealing ring.
Compared with the prior art the present invention has advantages below:
Present configuration is simple, compact, reasonable, stable and reliable in work, good airproof performance;Jie that can be blocked or connect in pipeline Matter, effective drift diameter is greatly improved, and fluid resistance diminishes, easy to maintenance.
Description of the drawings
Fig. 1 is front view of the present invention.
Description of reference numerals:1- valve bodies, 2- valve seats, 3- valve balls, 4- valve gaps, 5- sealing rings, 6- handles, 7- valve stem nuts, 8- valve rods, 9- glands, 10- outer fluid passages, 11- fluid passages.
Specific embodiment
Below the present invention is further described the embodiment combined in accompanying drawing:
As shown in figure 1, the invention mainly comprises being provided with the valve ball 3 that can freely rotate, valve body 1 in valve body 1 and valve ball 3, valve body 1 Two ends connect respectively valve gap 4, and valve seat 2 is provided between valve gap 4 and valve ball 3.
The upper end of valve ball 3 connects valve rod 8, and the upper end of valve rod 8 is stretched out valve body 1, gland 9 is provided between valve rod 8 and valve body 1.
The upper end of the valve rod 8 connects handle 6 and valve stem nut 7, and valve stem nut 7 is fastened on handle 6 on valve rod 8.
The valve gap 4 is provided with outer fluid through hole 10, and valve ball 3 is provided with fluid passage 11, and rotation valve rod is enabled to The outer fluid through hole 10 of valve gap 4 is connected or disconnected with the fluid passage 11 of valve ball 3.
The valve gap 4, valve body 1 and the junction of valve seat 2 are provided with sealing ring 5, and by sealing ring 5 sealing is improved.
The present invention operation principle be:During work, valve rod is caused to drive spheroid rotation by rotating handle, so that valve The outer fluid through hole of lid 4 is connected or disconnected with the fluid passage of valve ball.Present configuration is simple, compact, reasonable, working stability It is reliable, good airproof performance;The medium that can be blocked or connect in pipeline, effective drift diameter is greatly improved, and fluid resistance diminishes, maintenance side Just.
