Problems solved by technology

[0003] First, the high-speed fluid will seriously erode the inside of the valve body and the valve stem, valve core and other parts, resulting in serious wear of the valve stem and valve core, and even leakage of the valve body
The high-speed impact or fluctuation of the fluid will cause the valve stem to vibrate. When the valve is close to fully closed, the valve stem hangs out the longest. Damage to the spool or seat
[0004] Second, when the valve needs to be overhauled, it is necessary to remove the linear actuator and the bonnet mounted on the top with a large size and weight as a whole.
However, in some workstations, the space at the top is limited, and the height of the linear actuator often exceeds the standard, which may easily cause installation difficulties.

Embodiment 1

[0021] see figure 1 , which is a schematic structural view of the full-lined ceramic angle valve of the present invention, the full-lined ceramic angle valve includes a valve body 1, and the side and bottom of the valve body 1 are respectively provided with a side flange 2 and a bottom flange 3, and the bottom flange 3 The bottom valve seat 4 is arranged in the center hole, and the upper valve seat 5 is arranged on the top of the valve body 1, and the center of the bottom of the upper valve seat 5 extends to the center chamber of the valve body 1 to form an upper valve seat cavity 6, and the upper valve seat valve There is a gap between the outer wall of the cavity 6 and the inner wall of the valve body 1, and the fluid medium flows through the side flange 2, passes through the gap between the outer wall of the upper valve seat valve cavity 6 and the inner wall of the valve body 1, and flows from the bottom valve seat 4 The central hole flows out, thereby forming a channel for...

Embodiment 2

[0029] The difference between this embodiment and Embodiment 1 is that, in this embodiment, a ceramic sheath 22 with an opening at the bottom is sheathed on the outer side of the valve chamber 6 of the upper valve seat. The ceramic sheath 22 can further protect the upper valve seat 5 to prevent the high-velocity fluid from severely eroding or cavitating the outer surface of the upper valve seat 5 , thereby causing damage to the outer surface of the upper valve seat 5 . The ceramic sheath 22 is made of ceramic material, which has a better effect of wear resistance and corrosion resistance. In this embodiment, a sealing ring 23 is provided between the cylindrical valve core 9 , the bottom end of the upper valve seat 5 and the opening of the ceramic sheath 22 , and the sealing ring 23 can prevent fluid medium from flowing into the valve chamber 6 of the upper valve seat. It needs to be explained here, such as figure 1 As shown in , when the drive table cover 8 is set in this emb...

Abstract

The invention discloses a full-lining ceramic angle valve and relates to the technical field of valves, a valve body is provided with a side flange and a bottom flange, a bottom valve seat is arranged in a center hole of the bottom flange, an upper valve seat is arranged at the top of the valve body, and the center of the bottom of the upper valve seat extends into a center cavity of the valve body to form an upper valve seat valve cavity; a gap exists between the outer wall of the valve cavity of the upper valve seat and the inner wall of the valve body, a driving table is arranged on the other side of the valve body, the end, located in the center cavity of the valve body, of the driving table is erected on a driving table sleeve, a cylindrical valve element vertically penetrating through the bottom end of the upper valve seat is arranged in the valve cavity of the upper valve seat, and the outline of the bottom end of the cylindrical valve element is matched with the shape of a center hole of the bottom valve seat. And the top end of the cylindrical valve core is connected with a gear transmission device. The cylindrical valve element is driven by the gear transmission device wrapped in the valve cavity of the upper valve seat and slides up and down in the valve cavity to open and close the center hole sealing face of the bottom valve seat, the valve rod and the valve element cannot be directly eroded and cavitated by a high-speed fluid medium, and absolute protection on the interior of the valve body is formed.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a fully lined ceramic angle valve. Background technique [0002] The traditional angle valve is equipped with a straight-stroke actuator at the top, the valve stem hangs out of the valve cavity for a long time, the valve core is installed at the bottom of the valve stem and moves up and down with the valve stem to adjust the sealing surface of the valve core and valve seat The throttling area realizes the flow control of the angle valve, but this structure often encounters the following technical problems in practical applications: [0003] First, the high-speed fluid will seriously erode the inside of the valve body, the valve stem, the valve core and other parts, resulting in severe wear of the valve stem and valve core, and even external leakage of the valve. The high-speed impact or fluctuation of the fluid will cause the valve stem to vibrate. When the valve is close to full...
