Abstract
The utility model discloses a novel ball valve which comprises a valve body. The valve body is provided with a liquid inlet pipe and a liquid outlet pipe, a perpendicularly-formed circular valve rod hole is formed in the valve body, a valve rod is arranged in the valve rod hole in a penetrating mode, and the bottom of the valve rod is connected with a ball-shaped valve element arranged in the valve body. The novel ball valve is characterized in that a circular sinking groove is formed in the top of the valve rod hole, teflon serving as packing is arranged at the position, located between the valve rod and the valve body, in the sinking groove, a gland for pressing the packing is arranged at the opening portion of the sinking groove and fixedly connected with the valve body through a pressing bolt, a Z-shaped operating handle or Z-shaped operating disc is arranged at the top of the valve rod, and the bottom of the valve rod is detachably connected with the valve element. The novel ball valve is simple in structure, low in cost, compact in overall structure, small in occupied area after being installed, good in structure matching, small in relative abrasion after long-time use, and low in leakage probability.
Description
Technical field
The utility model relates to a kind of valve, in particular to a kind of ball valve.
Background technique
Ball valve, open-shut device (spheroid) is driven by valve rod, and the valve rotating around the axis of valve rod.Be mainly used in blocking or connecting the medium in pipeline, also can be used for adjusting and the control of fluid, wherein firmly seal between its V-type ball core of V-type ball valve and the metal seat valve of pile-up welding hard alloy and there is very strong shearing force, be specially adapted to the media such as fibre-bearing, small solid particle.And multi-pass ball valve not only switching of the interflow of control media, shunting and the flow direction flexibly on pipeline, the while also can be closed arbitrary passage and two other passage is connected.This class valve generally should level be installed in pipeline.Ball valve of the prior art easily produces the problem of revealing after long-term use.
Model utility content
The problems referred to above that exist in order to solve prior art, the utility model provides a kind of ball valve.
To achieve these goals, the utility model adopts following technological scheme:
A ball valve, has valve body, and described valve body has liquid inlet pipe and drain pipe, is provided with vertically arranged circular valve rod hole on valve body, in described valve rod hole, wears valve rod, and described stem bottom is connected with the spherical spool in being located at valve body, it is characterized in that:
Described valve rod hole top is provided with circular deep gouge, in deep gouge and be positioned between valve rod and valve body and be provided with the teflon as filler, at described deep gouge oral area, is provided with for compressing the gland of filler, and described gland is fixedly connected with described valve body by hold-down bolt;
Described valve rod top is provided with " Z " font operating grip or operating panel, and described stem bottom and spool removably connect.
Further: described gland is ring bodies, it has the first column section and the second column section that is positioned at top that is positioned at below, and the first column section external diameter is less than the second column section external diameter.
Further: described liquid inlet pipe has liquid input section, contraction section and First Transition section along media flow direction, described drain pipe has the second changeover portion, extending section and fluid section along media flow direction.
Further: liquid inlet pipe ingress is provided with the first flange-interface, drain pipe outlet port is provided with the second flange-interface.
Further: liquid inlet pipe, drain pipe and spherical spool coaxial arrangement.
Compared to existing technology, the utlity model has following advantage: the utility model is simple in structure, cost is lower; Compact overall structure, after installing, floor space is less; Each respective outer side edges is good, and after long-term use, relative wear is less, produces the probability of revealing lower.
Accompanying drawing explanation
Fig. 1 is a kind of ball valve structural representation.
Fig. 2 is I place enlarged view in Fig. 1.
In figure, 1-valve body, 2-valve rod, 21-operating grip, 3-spool, 41-liquid input section, 42-contraction section, 43-First Transition section, 51-the second changeover portion, 52-extending section, 53-fluid section, 61-the first column section, 62-the second column section, 7-filler.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
In this case, in figure, the direction of arrow represents media flow direction.
As Fig. 1, shown in 2, a kind of ball valve, there is valve body 1, described valve body 1 has liquid inlet pipe and drain pipe, on valve body 1, be provided with vertically arranged circular valve rod hole, in described valve rod hole, wear valve rod 2, described valve rod 2 bottoms are connected with the spherical spool 3 in being located at valve body, described valve rod hole top is provided with circular deep gouge, in deep gouge and be positioned at the teflon being provided with as filler 7 between valve rod and valve body and (include but are not limited to teflon, also can adopt other fillers), at described deep gouge oral area, be provided with for compressing the gland of filler, described gland is fixedly connected with described valve body by hold-down bolt, it can be also operating panel that described valve rod top is provided with " Z " font operating grip 21(), described valve rod 2 bottoms and spool 3 removably connect.Liquid inlet pipe, drain pipe and spherical spool coaxial arrangement.
Filler plays seal action, therefore valve opening top there will not be medium leakage problem, comparatively speaking, polytetrafluoroethylene packing cost is lower, and sealing effect is better, and using scope is relatively wide.The operating grip that valve rod top arranges and operating panel are used for rotary valve rod, and then drive spherical valve core rotation, open and close valve.Valve rod and spool removably connect, convenient manufacture and dismounting.
Described gland is ring bodies, and it has the second column section 62, the first column section external diameters that are positioned at the first column section 61 of below and are positioned at top and is less than the second column section external diameter.
After the first column section is installed, its integral body is placed in deep gouge, and for compressing filler, the second column section is used for coordinating hold-down bolt, realizes gland is fixed on to valve body.
Described liquid inlet pipe has liquid input section 41, contraction section 42 and First Transition section 43 along media flow direction, and described drain pipe has the second changeover portion 51, extending section 52 and fluid section 53 along media flow direction.
Liquid inlet pipe ingress is provided with the first flange-interface (not shown), and drain pipe outlet port is provided with the second flange-interface (not shown).
This ball valve is used comparatively simple, that is: staff's operating operation handle, drives spherical valve core rotation in the time of rotary valve rod, and then realizes the switching of ball valve.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
