Abstract
The utility model relates to a can restrict disk seat pivoted parallel single-disc gate valve. This parallel single flashboard gate valve is including valve body, valve rod, disk seat and flashboard, its characterized in that: the lower part of disk seat is equipped with the regulating block, the bottom of regulating block has the adjustment tank, the bottom of valve body is equipped with the guide block, the guide block is located the adjustment tank, be equipped with the restriction piece that is used for restricting the regulating block on the guide block. The parallel single-flashboard gate valve can prevent the valve seat from rotating, thereby ensuring the sealing performance of the gate valve.
Description
Technical Field
The utility model relates to a valve, concretely relates to parallel single-disc gate valve.
Background
The gate valve is a commonly used valve, and generally comprises a valve body, a valve rod, a valve seat and a gate plate. The valve rod drives the flashboard to move up and down, the flashboard acts on the valve seat, and when the flashboard is separated from or partially separated from the valve seat, the gate valve is opened. However, the valve seat of the existing gate valve only leans against the valve body by the spring, and under the action of the medium and the gate plate, the valve seat may slightly rotate around the axis, and the rotation of the valve seat has the effect of affecting the sealing effect.
Disclosure of Invention
In view of the deficiencies in the prior art, the utility model discloses the innovation provides a can restrict parallel single flashboard gate valve of disk seat pivoted. This parallel single flashboard gate valve is including valve body, valve rod, disk seat and flashboard, its characterized in that: the lower part of disk seat is equipped with the regulating block, the bottom of regulating block has the adjustment tank, the bottom of valve body is equipped with the guide block, the guide block is located the adjustment tank, be equipped with the restriction piece that is used for restricting the regulating block on the guide block.
The limiting piece is connected to the guide block through a bolt.
The valve is characterized in that a plurality of spring grooves are formed in the outer side face of the valve seat along the circumference, a spring is arranged in each spring groove, a limiting groove for limiting outward movement of the valve seat is formed in the valve body, and the spring acts on the side face of the limiting groove.
And an O-shaped sealing ring is arranged on the valve seat and acts on the side surface of the limiting groove.
The valve seat is provided with a fire collar which acts on the bottom of the limiting groove.
The fire collar is a graphite braided rope.
According to the utility model provides a pair of parallel single-disc gate valve can prevent that the disk seat from rotating to guarantee the sealing performance of gate valve.

Detailed Description
As shown in fig. 1-3, the parallel single-gate valve includes a valve body 10, a valve rod 11, a valve seat 2 and a gate plate 1, wherein an adjusting block 3 is disposed at a lower portion of the valve seat 2, an adjusting groove is disposed at a bottom of the adjusting block 3, a guide block 6 is disposed at a bottom of the valve body 10, the guide block 6 is located in the adjusting groove 30, and a limiting member 5 for limiting the adjusting block 3 is disposed on the guide block 6. When the gate valve is closed, the valve seat 2 acts on the gate plate 1; when the gate valve is opened, the gate plate 1 moves upwards, the valve seat 2 moves on the guide block 6 through the adjusting block 3 to realize axial floating, and the limiting piece 5 limits the valve seat 2 to float within a certain range because the guide block 6 is positioned in the adjusting groove 30 of the adjusting block 3. The guide block 6 also functions to restrict the rotation of the valve seat 2, thereby ensuring the stability and sealing of the valve seat 2.
In order to adjust the height of the limiting member 5, the limiting member 5 is connected to the guide block 6 by means of bolts 4. By adjusting the bolts 4, the height of the limiting piece 5 can be adjusted.
In order to enable the valve seat 2 to have a floating effect, a plurality of spring grooves are formed in the outer side face of the valve seat 2 along the circumference, a spring 7 is arranged in each spring groove, a limiting groove for limiting outward movement of the valve seat 2 is formed in the valve body 10, and the spring 7 acts on the side face of the limiting groove.
In order to obtain a sealing effect, an O-ring 8 is arranged on the valve seat 2, and the O-ring 8 acts on the side surface of the limiting groove.
In order to enable the gate valve to have a fireproof function, a fireproof ring 9 is arranged on the valve seat 2, and the fireproof ring 9 acts on the bottom of the limiting groove. The fire collar 9 is a graphite braided rope.
