Abstract
The utility model discloses a press from both sides cover ball valve, including valve body and the flange of dress in the valve body both sides, be equipped with the flange through-hole on the flange, install a direct pipe between the flange of valve body both sides, the both ends of this direct pipe respectively with the flange through-hole connection of valve body both sides, direct intraductal bolt for the locking of installing, with the flange toward valve body direction locking, direct pipe is the steel pipe to through welding mode fixed mounting on the flange. The utility model discloses a set up direct pipe, can not produce extra pressure to the valve body during locking flange, reduce the intensity requirement of valve body.
Description
Technical Field
The utility model relates to a ball valve, specifically speaking are press from both sides cover ball valve.
Background
The jacket ball valve has good heat preservation and cold insulation characteristics, the drift diameter of the valve is consistent with the pipe diameter, and the heat loss of media in a pipeline can be effectively reduced. The device is mainly used in various systems such as petroleum, chemical engineering, metallurgy, pharmacy, food and the like to convey high-viscosity media which can be solidified at normal temperature. The jacket ball valve is characterized in that a metal jacket is welded on the basis of the ball valve and used for injecting steam or other heat-preservation and cold-preservation media to ensure that the media in the valve can work normally.
The existing clamping sleeve ball valve needs to be a blind hole and a threaded hole for preventing a heating medium in a clamping sleeve from leaking outwards after the clamping sleeve is welded. When adding man-hour, the time part is bored and is attacked the screw thread, can not guarantee that the screw hole of valve both sides is concentric completely, and is the screw hole, when the dress pipeline, has two power in other words and draws the valve toward both sides with the valve body, produces extra intensity requirement to the structure valve body that itself is just comparatively compact, simultaneously, when processing the screw hole, has the risk of boring through with the screw hole. As shown in the attached figure 1, the flanges 2 on the two sides of the valve body 1 are provided with flange holes 3 which are blind holes, and bolts are locked in the flange holes. When processing man-hour, each flange all separately drills and taps, is difficult to guarantee that the flange hole of valve body both sides flange is concentric, and when the dress pipeline, the flange hole of both sides all locks the bolt, just has two power to act on the valve body in other words, toward both sides pulling valve body to make the valve body that needs higher intensity.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a press from both sides cover ball valve.
In order to solve the technical problem, the utility model discloses take following technical scheme:
a jacket ball valve comprises a valve body and flanges arranged on two sides of the valve body, wherein flange through holes are formed in the flanges, a straight-through pipe is arranged between the flanges on the two sides of the valve body, two ends of the straight-through pipe are respectively connected with the flange through holes on the two sides of the valve body, and a locking bolt is arranged in the straight-through pipe and used for locking the flanges in the direction of the valve body.
The straight-through pipe is a steel pipe.
And two ends of the straight-through pipe are inserted into the flange through holes of the flanges at the corresponding sides.
The straight-through pipe and the flange are fixedly installed in a welding mode.
The axis of the straight-through pipe and the axis of the flange through hole are on the same horizontal line.
The utility model discloses a set up direct pipe, can not produce extra pressure to the valve body during locking flange, reduce the intensity requirement of valve body, reduce the processing degree of difficulty of valve body.

fig. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
As shown in the attached drawing 2, the utility model discloses a press from both sides cover ball valve, including valve body 1 and the flange 2 of dress in 1 both sides of valve body, be equipped with the flange through-hole on the flange, install a direct pipe 3 between the flange of valve body both sides, the both ends of this direct pipe are connected with the flange through-hole of valve body both sides respectively, and direct intraductal bolt for the locking of installing is locked the flange toward the valve body direction. The straight-through pipe is a steel pipe, so that the pipe is more durable, is not easy to damage and prolongs the service life.
And two ends of the straight-through pipe are inserted into the flange through holes of the flanges at the corresponding sides. The flanges on two sides of the valve body are symmetrically arranged on two sides of the valve body, flange holes are respectively arranged at corresponding positions of the flanges on two sides of the valve body, and the straight-through pipe is arranged at a position corresponding to the flange holes.
The straight-through pipe and the flange are fixedly installed in a welding mode, and installation stability is guaranteed.
The axis of the straight-through pipe and the axis of the flange through hole are on the same horizontal line. Through the assembly of the straight-through pipe, the flange holes of the flanges on the two sides of the valve body are ensured to be positioned on the same axis, and the concentricity is ensured.
A straight-through pipe is utilized, two ends of the straight-through pipe are respectively inserted into flange holes of flanges on two sides of a valve body between the flanges on the two sides of the valve body, and the port of the straight-through pipe and the port of the flange hole are kept flush, so that the structure is simpler and more compact. The straight-through pipe is of a straight-through structure, so that the straight-through pipe equivalently penetrates through the whole valve body. When the bolt is locked, the bolt is locked into the through pipe, the flange is locked in the direction of the valve body, the flange cannot be pulled outwards, therefore, extra acting force cannot be exerted on the valve body, and the strength requirement on the valve body is reduced.
It should be noted that the above is only a preferred embodiment of the present invention, and the present invention is not limited to the above, and although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be replaced with equivalents, but any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
