Description
Technical field
The utility model relates to a kind of shut-off valve, specifically a kind of flange form shut-off valve.
Background technique
Shut-off valve is also known as pipe valve valve, belongs to forced seal formula valve, so when valve is closed, it is necessary to apply to flap and press
Power is not leaked with forced seal face.When medium is by entering valve below flap, the resistance overcome required for operating force, is valve
The frictional force of bar and filler and the thrust as caused by the pressure of medium, the power of closing valve is bigger than the power of valve opening door, so valve rod
Diameter it is big, the failure of valve rod bending otherwise can occur.It is divided into three kinds by connection type: flanged joint, screwed connection, welding
Connection.
Present flange form shut-off valve is typically all only one medium channel, is unfavorable for the adjusting of rate-of flow, is adjusted
Range is relatively narrow.Therefore, those skilled in the art provide a kind of flange form shut-off valve, mentioned above in the background art to solve
Problem.

The side for stating the nearly valve body center of filler is provided with filler washer, and the valve body upper and lower ends are provided with valve rod, the valve rod
One end is provided with hand lever, is equipped with flush end holding screw inside the right side of the hand lever, the left end of the flush end holding screw with
Valve stem contacts, the other end of the valve rod sequentially pass through gland, filler and filler washer and are arranged in valve inner, and
The end that valve rod is located at valve inner is equipped with flap.
As a further solution of the present invention: the valve body left side central portion is set as import, and valve body right side central
It is set as exporting.
It is opened up between two flaps and outlet in the valve body as a further solution of the present invention,
There is exit passageway.
The valve rod outer surface is provided with external screw thread, and gland as a further solution of the present invention,
Middle inside is provided with internal screw thread.
Pass through external screw thread and internal screw thread between the valve rod and gland as a further solution of the present invention,
It is threadedly coupled.
Compared with prior art, the utility model has the beneficial effects that
There are two mutually isostructural valve control devices for tool in the utility model, and medium flow field can be made by opening one or two
It is logical, it is easy to use, while two channels are conducive to the adjusting to rate-of flow, unlike other valve mechanisms, other valves
Door cannot can only be carried out again after valve fully opens by the flow of the Space adjustment medium between spool and valve body
It adjusts, and the valve in the utility model can increase the flow of valve by increasing medium channel, make its flow adjustment range
Bigger, structure design is simple, novel, practical.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of flange form shut-off valve.
In figure: 1- valve body, 2- filler washer, 3- filler, 4- gland, 5- valve rod, 6- hand lever, 7- flush end clamp screw
Nail, 8- flap, 9- six square nuts.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, in the utility model embodiment, a kind of flange form shut-off valve, including valve body 1, about 1 valve body
Both ends are provided with gland 4, and one end setting of the gland 4 covers inside valve body 1, and on the gland 4
Equipped with six square nuts 9, the six square nuts 9 are threadedly coupled gland 4, and the side of six square nuts 9 is contacted with valve body 1,
Medial surface in the valve body 1 in gland 4 is provided with filler 3, and the side at nearly 1 center of valve body of the filler 3, which is provided with, to be filled out
Backing strap circle 2,1 upper and lower ends of valve body are provided with valve rod 5, and one end of the valve rod 5 is provided with hand lever 6, the hand lever 6
Flush end holding screw 7 is installed inside right side, the left end of the flush end holding screw 7 is contacted with valve rod 5, the valve rod 5 it is another
One end sequentially passes through gland 4, filler 3 and filler washer 2 and is arranged inside valve body 1, and valve rod 5 is located in valve body 1
The end in portion is equipped with flap 8.
1 left side central portion of valve body is set as import, and 1 right side central of valve body is set as exporting.
Exit passageway is offered between two flaps 8 and outlet in the valve body 1.
5 outer surface of valve rod is provided with external screw thread, and 4 middle inside of gland is provided with internal screw thread.
It is threadedly coupled between the valve rod 5 and gland 4 by external screw thread and internal screw thread.
The working principle of the utility model is:
In the utility model the inside of valve body 1 up and down two sides be provided with filler washer 2, filler 3, gland 4, valve rod 5,
Hand lever 6 and flap 8 are structure symmetrical above and below, i.e., there are two valve control devices, the utility model to exist for installation in valve body 1
When work, opening any one valve control device can be such that valve is connected, but must be by two valve controls to close valve
