Description
Art
The present invention relates to a kind of gate valve, the lumen over-pressure safety device of a kind of gate valve.
Background technology
Gate valve has the advantages such as simple in construction, sealing property be reliable, is widely used in electric power, chemical engineering piping systems.But
The phenomenon of lumen pressure anomaly can be produced under some special operation condition, when being high-temperature, high pressure fluid such as medium, if upstream side fluid
Temperature raises, and lumen fluid can synchronize to raise, and owing to middle cavity volume cannot expand, blocking the fluid at lumen may gas rapidly
Change, cause pressure drastically to raise, thus cause damage and the damage of pipe-line equipment.
Traditional lumen pressure release mode has two kinds, and one is to offer pressure release passage on valve plate, makes lumen and upstream line
It is connected, when central cavity pressure raises, pressure releasing can be made in upstream line by pressure release passage；Another kind is at valve
External body sets up relief pipeline, i.e. is connected with upstream by lumen outside valve body by pipeline, and is provided with cut-off on pipeline
Valve, for blocking of lumen and upstream line.Above two method the most all must be noted that installation direction is asked
Topic, i.e. pressure release passage must communicate with upstream, if installing the effect that not only can not realize pressure release the most on request, and can cause lock
Valve cannot realize the function blocked, and there is potential safety hazard.
Summary of the invention
It is an object of the invention to provide lumen over-pressure safety device a kind of rational in infrastructure, that do not limited by installation direction.
The technical solution adopted for the present invention to solve the technical problems is, the lumen overvoltage of a kind of harsh operating mode gate valve is protected
Protection unit, including triple-valve body, offers runner A, runner B and runner C in triple-valve body, runner A connects with the lumen of gate valve
Logical, in runner B and runner C, core member B and core member C are installed, between core member B and core member C, form spherical valve pocket, spherical
Being provided with spheroid in valve pocket, the internal diameter of spherical valve pocket is slightly larger than spheroid external diameter, and core member B and core member C are bolted sealing
In triple-valve body；Spherical valve pocket is connected with described runner A, core member B and core member C are offered respectively medium pod apertures B and
Medium pod apertures C, medium pod apertures B and medium pod apertures C are connected respectively at the runner D and runner E with gate valve by pipeline；
When runner D is upstream extremity, and runner E is downstream, at medium pod apertures B, pressure is more than the pressure at medium pod apertures C,
Spheroid pushes core member C under the effect of medium power to, and the lumen of gate valve is connected with runner B by runner A；
When runner E is upstream extremity, and runner D is downstream, at medium pod apertures C, pressure is more than the pressure at medium pod apertures B,
Spheroid pushes core member B under the effect of medium power to, and the lumen of gate valve is connected with runner C by runner A.
The invention has the beneficial effects as follows: the installation direction of device is not limited by upstream and downstream direction, exchange upstream and downstream direction
Equally can realize the function of lumen pressure release, and pressure leak process is without manual operation, safe and reliable.

Detailed description of the invention
As shown in Figure 1, 2, the lumen over-pressure safety device of a kind of harsh operating mode gate valve, including triple-valve body 5, triple-valve body 5
Inside offering runner A6, runner B1 and runner C11, runner A6 connects with the lumen 14 of gate valve, divides in runner B6 and runner C11
Core member B3 and core member C10 are not installed, form spherical valve pocket 7 between core member B3 and core member C10, in spherical valve pocket 7
Being provided with spheroid 8, the internal diameter of spherical valve pocket 7 is slightly larger than spheroid 8 external diameter, core member B3 and core member C10 by bolt 2 fixing seal
In triple-valve body 5；Spherical valve pocket 7 is connected with described runner A6, and core member B3 and core member C10 are offered medium water conservancy diversion respectively
Hole B4 and medium pod apertures C9, medium pod apertures B4 and medium pod apertures C9 by pipeline respectively at the runner D12 of gate valve and
Runner E13 is connected；
When runner D12 is upstream extremity, and runner E13 is downstream, at medium pod apertures B4, pressure is more than at medium pod apertures C9
Pressure, owing to the internal diameter of spherical valve pocket 7 is slightly larger than spheroid 8 external diameter, the internal diameter of general spherical valve pocket 7 is than the spheroid 8 big 1-of external diameter
2mm, spheroid 8 moment under the effect of medium power pushes core member C10 to so that runner B1 and runner C11 blocks, the lumen of gate valve
14 are connected with runner B1 by runner A6, it is achieved releasing of lumen 14 pressure；
Ibid principle, when runner E13 is upstream extremity, and runner D12 is downstream, at medium pod apertures C9, pressure is led more than medium
Pressure at discharge orifice B4, spheroid 8 moment under the effect of medium power pushes core member B3 to so that runner B1 and runner C11 cuts
Disconnected, the lumen 14 of gate valve is connected with runner C11 by runner A6, it is achieved releasing of lumen 14 pressure.
