A kind of lumen over-pressure safety device of harshness operating condition gate valve; including triple-valve body; runner A, runner B and runner C are offered in triple-valve body; runner A is connected to the lumen of gate valve; core member B and core member C are installed in runner B and runner C; spherical valve chamber is formed between core member B and core member C, globe valve is intracavitary to be equipped with sphere, and core member B and core member C are bolted and are sealed in triple-valve body；Spherical valve chamber is connected with the runner A, opens up medium deflector hole B and medium deflector hole C, medium deflector hole B and medium deflector hole C on valve core part B and core member C respectively and is connected by pipeline respectively at the runner D of gate valve and runner E.The beneficial effects of the present invention are: the installation direction of device is not limited by upstream and downstream direction, the function of lumen pressure release is equally may be implemented in exchange upstream and downstream direction, and pressure leak process is not necessarily to manual operation, securely and reliably.
Description
Technical field
The present invention relates to a kind of gate valve, the lumen over-pressure safety device of especially a kind of gate valve.
Background technique
Gate valve has many advantages, such as that structure is simple, sealing performance is reliable, is widely used in electric power, in chemical engineering piping systems.But
The phenomenon that lumen pressure anomaly can be generated under certain special operation conditions, as medium be high-temperature, high pressure fluid when, if upstream side liquid
Temperature increases, and lumen fluid can synchronize raising, and since middle cavity volume can not expand, closure may rapid gas in the fluid of lumen
Change, causes pressure sharply to increase, so as to cause the damage and damage of pipe-line equipment.
There are two types of traditional lumen pressure release modes, one is pressure release passage is opened up on valve plate, makes lumen and upstream line
It is connected, pressure releasing can be made into upstream line by pressure release passage when cavity pressure increases in the middle；Another kind is in valve
Relief pipeline is added outside body, that is, lumen is connected outside valve body with upstream by pipeline, and is provided with cut-off on pipeline
Valve, the truncation for lumen and upstream line.Above two method all must be noted that installation direction is asked in actual use
Topic, i.e., pressure release passage must be communicated with upstream, if not installing not only the effect that can not achieve pressure release as required, but also will lead to lock
Valve cannot achieve the function of truncation, and there are security risks.
Summary of the invention
The purpose of the present invention is to provide a kind of structurally reasonable, lumen over-pressure safety devices not limited by installation direction.
The technical solution adopted by the present invention to solve the technical problems is a kind of lumen over-voltage guarantor of harshness operating condition gate valve
Protection unit, including triple-valve body, offer runner A, runner B and runner C in triple-valve body, and the lumen of runner A and gate valve connects
It is logical, core member B and core member C are installed in runner B and runner C, form spherical valve chamber between core member B and core member C, it is spherical
Sphere is equipped in valve chamber, the internal diameter of spherical valve chamber is slightly larger than sphere outer diameter, and core member B and core member C are bolted sealing
In triple-valve body；Spherical valve chamber is connected with the runner A, opened up respectively on core member B and core member C medium deflector hole B and
Medium deflector hole C, medium deflector hole B and medium deflector hole C are connected by pipeline respectively at the runner D of gate valve and runner E；
When runner D is upstream end, and runner E is downstream, pressure is greater than at medium deflector hole C at medium deflector hole B
Pressure, sphere push core member C under the action of medium power, and the lumen of gate valve is connected to by runner A with runner B；
When runner E is upstream end, and runner D is downstream, pressure is greater than at medium deflector hole B at medium deflector hole C
Pressure, sphere push core member B under the action of medium power, and the lumen of gate valve is connected to by runner A with runner C.
The beneficial effects of the present invention are: the installation direction of device is not limited by upstream and downstream direction, upstream and downstream direction is exchanged
The function of lumen pressure release equally may be implemented, and pressure leak process is not necessarily to manual operation, securely and reliably.

Specific embodiment
As shown in Figure 1, 2, a kind of lumen over-pressure safety device of harsh operating condition gate valve, including triple-valve body 5, triple valve
Runner A6, runner B1 and runner C11 are offered in body 5, runner A6 is connected to the lumen 14 of gate valve, runner B6 and runner C11
It is inside separately installed with core member B3 and core member C10, forms spherical valve chamber 7, spherical valve chamber between core member B3 and core member C10
Sphere 8 is equipped in 7, the internal diameter of spherical valve chamber 7 is fixed by bolt 2 slightly larger than 8 outer diameter of sphere, core member B3 and core member C10
It is sealed in triple-valve body 5；Spherical valve chamber 7 is connected with the runner A6, opens up medium respectively on core member B3 and core member C10
Deflector hole B4 and medium deflector hole C9, medium deflector hole B4 and medium deflector hole C9 pass through pipeline respectively at the runner with gate valve
D12 is connected with runner E13；
When runner D12 is upstream end, and runner E13 is downstream, pressure is greater than medium deflector hole at medium deflector hole B4
Pressure at C9, since the internal diameter of spherical valve chamber 7 is slightly larger than 8 outer diameter of sphere, the internal diameter of general spherical shape valve chamber 7 is than 8 outer diameter of sphere
Big 1-2mm, moment under the action of medium power of sphere 8 push core member C10 to, so that runner B1 and runner C11 truncation, gate valve
Lumen 14 is connected to by runner A6 with runner B1, realizes releasing for 14 pressure of lumen；
Ibid principle, pressure, which is greater than, when runner E13 is upstream end, and runner D12 is downstream, at medium deflector hole C9 is situated between
Pressure at matter deflector hole B4, moment under the action of medium power of sphere 8 pushes core member B3 to, so that runner B1 and runner C11
The lumen 14 of truncation, gate valve is connected to by runner A6 with runner C11, realizes releasing for 14 pressure of lumen.
