Abstract

The utility model discloses a valve body structure of a vacuum-resistant lining regulating valve, which comprises a valve body and a sealing cover, wherein a through-type middle cavity is arranged in the valve body in a hollow manner, medium flowing channels communicated with the through-type middle cavity are respectively arranged at the left end and the right end of the valve body, the opposite ends of the two medium flowing channels are respectively communicated with connecting flanges fixed on the valve body, and anti-vacuum linings are respectively arranged on the two medium flowing channels, the outer end surfaces of the two connecting flanges and the inner wall of the through-type middle cavity. In the device, the middle cavity of the valve body is of a straight-through structure, the middle cavity has no dead angle, the lining layer has good fluidity, the lining effect is more stable, and the bottom port of the valve body is sealed by the PTFE gasket and the sealing cover.

Description

Valve body structure of vacuum-resistant lining regulating valve
Technical Field
The utility model particularly relates to the technical field of valves, in particular to a valve body structure of a vacuum-resistant lining regulating valve.
Background
The valve is a control part in a pipeline fluid conveying system, is used for changing the section of a passage and the flowing direction of a medium, and has the functions of diversion, cut-off, throttling, non-return, shunt or overflow pressure relief and the like; at present, due to different working conditions, the valve seat of the existing regulating valve is very limited, so that the lining layer of the valve seat is easy to deform in a vacuum environment.
SUMMERY OF THE UTILITY MODEL
Therefore, the present invention provides a valve body structure of a vacuum-resistant lining regulating valve to solve the problems in the background art.
In order to achieve the purpose, the utility model provides the following technical scheme: a vacuum-resistant lining regulating valve body structure comprises a valve body and a sealing cover, wherein a through type middle cavity is arranged in the valve body in a hollow mode, medium flowing channels communicated with the through type middle cavity are arranged at the left end and the right end of the valve body, connecting flanges fixed on the valve body are respectively communicated with the opposite ends of the two medium flowing channels, and vacuum-resistant linings are arranged on the two medium flowing channels, the outer end faces of the two connecting flanges and the inner wall of the through type middle cavity;
the closing cap is sealed set up in the bottom port department of valve body to adopt a plurality of bolts to fix.
Preferably, a teflon gasket is disposed between the bottom end surface of the valve body and the top end surface of the sealing cover.
By adopting the technology, compared with the prior art, the utility model has the following beneficial effects:
1. in the device, the middle cavity of the valve body is of a straight-through structure, the middle cavity has no dead angle, the lining layer has good fluidity, the lining effect is more stable, and the bottom port of the valve body is sealed by the PTFE gasket and the sealing cover.
2. In the device, when the valve body is lined, the upper lining layer and the lower lining layer of the valve body are firmly limited through a circle of vertical through holes, and the inner lining layer of the valve body is ensured not to deform in a vacuum environment.
3. In the device, the outer end faces and the middle cavity of the two connecting flanges are both designed with vacuum-proof inlays so as to ensure that the inner lining layer is damaged by the internal and external pressure difference when the valve is internally vacuumized.
Drawings
FIG. 1 is a schematic cross-sectional view of a valve body structure of a vacuum-resistant lining regulator valve;
fig. 2 is a schematic cross-sectional view a-a of fig. 1.
In the figure: 1. a valve body; 2. a straight-through lumen; 3. a tetrafluoro spacer; 4. a bolt; 5. sealing the cover; 6. a connecting flange; 7. a medium flows through the channel; 8. prevent the vacuum and inlay the lining.
Detailed Description
The technical solution of the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Example (b): referring to fig. 1 and 2, the present invention provides a technical solution: a valve body structure of a vacuum-resistant lining regulating valve comprises a valve body 1 and a sealing cover 5, wherein a through type middle cavity 2 is arranged in the valve body 1 in a hollow mode, medium flowing channels 7 communicated with the through type middle cavity 2 are arranged at the left end and the right end of the valve body 1, the opposite ends of the two medium flowing channels 7 are respectively communicated with connecting flanges 6 fixed on the valve body 1, and vacuum-resistant linings 8 are arranged on the outer end faces of the two medium flowing channels 7 and the outer end faces of the two connecting flanges 6 and the inner wall of the through type middle cavity 2 so as to ensure that when the valve is in vacuum inside, the inner lining layer is damaged by the inner and outer pressure difference; specifically, when the valve body 1 is lined, the upper lining layer and the lower lining layer of the valve body 1 are firmly limited through a circle of vertical through holes, and the lining layer of the valve body 1 is ensured not to deform in a vacuum environment;
the sealing cover 5 is arranged at the bottom port of the valve body 1 in a sealing mode and is fixed by a plurality of bolts 4.
In this embodiment, a tetrafluoro gasket 3 is provided between the bottom end surface of the valve body 1 and the top end surface of the cap 5.
During specific implementation, the middle cavity of the valve body 1 is of a straight-through structure, the middle cavity has no dead angle, the lining layer has good fluidity, the lining effect is more stable, and the bottom port of the valve body 1 is sealed by the PTFE gasket 3 and the sealing cover 5.
The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
