Abstract
Provided is a novel ball valve. The problem that an existing ball valve cannot change the diameter of a connecting port is mainly solved. The novel ball valve is characterized in that two sides of a valve body are provided with pipe connectors, the valve body is tightly adhered to the pipe connectors, and the circumferential faces of the outer sides of the pipe connectors are provided with bosses. Fastening covers are arranged at the connecting positions where the valve body is connected with the pipe connectors, and annular buttons clamped with the bosses of the pipe connectors are arranged on the fastening covers. The fastening covers are fixed on the outer side faces of the valve body and a valve cover. After the size of a pipeline in a system is changed, the whole ball valve is not required to be replaced, only the pipe connectors of the ball valve are replaced, and novel pipe connectors are installed.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of ball valve.
Background technique
The open-shut device of ball valve (spheroid) is driven by valve rod, and around the valve that the axis of valve rod rotates, and is mainly used in blocking or connect the medium in the pipeline, also can be used for adjusting and the control of fluid.Ball valve has and revolves the action that turn 90 degrees, and faucet body is spheroid, manhole or passage is arranged by its axis.Ball valve is mainly used to make cut-out, distributes and change the flow direction of medium in pipeline, only need just can close tightly with revolving the operation that turn 90 degrees and very little moment of rotation.
The main feature of ball valve is compact structure own, sealing is reliable, simple in structure, easy to maintenance, sealing surface and the sphere closed state of being everlasting, be difficult for by the medium erosion, easy operating and maintenance are applicable to general work media such as water, solvent, acid and rock gas, but also are applicable to the medium that operating conditions is abominable, as oxygen, hydrogen peroxide, methane and ethene etc., be widely used in every profession and trade.Ball valve body can be whole, also can be knockdown.
But the connection mouth diameter of existing ball valve is fixed, and when the pipeline of whole system changes, can only discard whole ball valve and uses the ball valve of other diameters instead, like this for resource waste very.
The model utility content
In order to overcome disadvantages of background technology, the utility model provides a kind of ball valve, has mainly solved the problem that existing ball valve can not change the connection mouth diameter.
The technological scheme that the utility model adopts is: a kind of ball valve, comprise valve body, valve gap, spheroid, valve rod and operating device, described valve rod downside is connected with spheroid, upside is connected with operating device, described valve body both sides are provided with pipe joint, described valve body and pipe joint are close to, and described pipe joint outer circumference face is provided with boss; The joint of described valve body and pipe joint is provided with fastening cover, and described fastening cover is provided with the ring buckle that the boss with pipe joint blocks mutually; Described fastening cover is fixed on the outer side surface of valve body and valve gap.
Be provided with sealing seat between described pipe joint and the spheroid, described sealing seat and spheroid joint are provided with sealing gasket, and described sealing gasket is rubber.
Described fastening cover is fixed on the outer side surface of valve body and valve gap by screw thread.
Be provided with the O RunddichtringO between described valve body and the pipe joint.
The beneficial effects of the utility model are: owing to take technique scheme, after the pipeline size in the system has become, do not need the integral replacing ball valve, only need be changed the pipe joint of this ball valve, load onto again to get final product.

Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
As shown in Figure 1, a kind of ball valve, comprise valve body 1, valve gap 2, spheroid 3, valve rod 4 and operating device 5, described valve rod 4 downsides are connected with spheroid 3, upside is connected with operating device 5, described valve body 1 both sides are provided with pipe joint 6, and described valve body 1 is close to pipe joint 6, and described pipe joint 6 outer circumference faces are provided with boss 7; Described valve body 1 is provided with fastening cover 8 with the joint of pipe joint 6, and described fastening cover 8 is provided with the ring buckle 9 that the boss 7 with pipe joint 6 blocks mutually; Described fastening cover 8 is fixed on the outer side surface of valve body 1 and valve gap 2.Described fastening cover 8 is fixed on the outer side surface of valve body 1 and valve gap 2 by screw thread.Be provided with sealing seat 10 between described pipe joint 6 and the spheroid 3, described sealing seat 10 is provided with sealing gasket 11 with spheroid 3 joints, and described sealing gasket 11 is rubber.Be provided with O RunddichtringO 12 between described valve body 1 and the pipe joint 6.
When this ball valve of assembling, at first sealing gasket 11 is put in the valve body 1, cover valve gap 2 then, be close to the valve body both sides with pipe joint 6, the ring buckle 9 with fastening cover 8 blocks with boss 7 then, be spun on again on valve body 1 and the valve gap 2 and fix, so just finished the assembling of ball valve, when needs are changed pipe joint 6, otherwise operation gets final product, do not need the integral replacing ball valve, saved resource.
Every technician's notice: though the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
