Abstract
The utility model provides a lumen overvoltage protector of harshness gate valve for operating mode, includes triple -valve body, has offered runner A, runner B and runner C in the triple -valve body, and runner A feeds through with the lumen of gate valve, installs case spare B and case spare C in runner B and the runner C, forms spherical valve pocket between case spare B and the case spare C, and the spherical valve intracavity is equipped with the spheroid, and case spare B and case spare C pass through bolt fixed seal in triple -valve body, spherical valve pocket with runner A links to each other, sets up medium water conservancy diversion hole B and medium water conservancy diversion hole C on valve case spare B and the case spare C respectively, and medium water conservancy diversion hole B and medium water conservancy diversion hole C pass through the pipeline and link to each other in runner D with the gate valve and runner E respectively. The beneficial effects of the utility model are that: the installation direction of device does not receive the restriction of upstream and downstream direction, and exchange upstream and downstream direction equally can realize the function of lumen pressure release, and the pressure release process need not manual operation, safe and reliable.
Description
Art
The utility model is related to a kind of gate valve, the lumen over-pressure safety device of particularly a kind of gate valve.
Background technology
Gate valve has the advantages that simple structure, sealing property are reliable, in being widely used in electric power, chemical engineering piping systems.But
The phenomenon of lumen pressure anomaly can be produced under some special operation conditions, when such as medium is high-temperature, high pressure fluid, if upstream side liquid
Temperature is raised, and lumen fluid synchronous can be raised, and because middle cavity volume cannot expand, the fluid blocked in lumen may gas rapidly
Change, cause pressure drastically to raise, so as to cause the damage and damage of pipe-line equipment.
Traditional lumen pressure release mode has two kinds, and one kind is that pressure release passage is opened up on valve plate, makes lumen and upstream line
It is connected, pressure releasing can be made in upstream line by pressure release passage when central cavity pressure is raised；Another kind is in valve
External body sets up relief pipeline, i.e. by pipeline lumen is connected with upstream outside valve body, and cut-off is provided with pipeline
Valve, for blocking for lumen and upstream line.Above two method all must be noted that in actual use installation direction is asked
Topic, i.e., pressure release passage must be communicated with upstream, if do not install on request can not only realize the effect of pressure release, and can cause lock
Valve cannot realize the function of blocking, and there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of rational in infrastructure, the lumen overvoltage protection dress not limited by installation direction
Put.
The utility model solves the technical scheme that its technical problem adopted, a kind of lumen mistake of harsh operating mode gate valve
Pressure protection device, including triple-valve body, offer runner A, runner B and runner C, in runner A and gate valve in triple-valve body
Chamber connects, and in runner B and runner C core member B and core member C are provided with, and spherical valve pocket is formed between core member B and core member C,
Spheroid is provided with spherical 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
It is sealed in triple-valve body；Spherical valve pocket is connected with the runner A, opens up medium pod apertures in core member B and core member C respectively
B and medium pod apertures C, medium pod apertures B and medium pod apertures C are by pipeline respectively at the runner D with gate valve and runner E phases
Even；
When runner D is upstream end, and runner E is downstream, pressure is more than at medium pod apertures C at medium pod apertures B
Pressure, spheroid pushes core member C in the presence of medium power, and the lumen of gate valve is connected by runner A with runner B；
When runner E is upstream end, and runner D is downstream, pressure is more than at medium pod apertures B at medium pod apertures C
Pressure, spheroid pushes core member B in the presence of medium power, and the lumen of gate valve is connected by runner A with runner C.
The beneficial effects of the utility model are：The installation direction of device is not limited by upstream and downstream direction, exchanges upstream and downstream
Direction can equally realize the function of lumen pressure release, and pressure leak process is without the need for manual operation, safe and reliable.

Specific embodiment
As shown in Figure 1, 2, a kind of lumen over-pressure safety device of harsh operating mode 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 with the lumen 14 of gate valve, runner B6 and runner C11
Core member B3 and core member C10 are inside separately installed with, spherical valve pocket 7, spherical valve pocket are formed between core member B3 and core member C10
Spheroid 8 is provided with 7, the internal diameter of spherical valve pocket 7 is slightly larger than the external diameter of spheroid 8, and core member B3 and core member C10 are fixed by bolt 2
It is sealed in triple-valve body 5；Spherical valve pocket 7 is connected with the runner A6, opens up medium in core member B3 and core member C10 respectively
Pod apertures B4 and medium pod apertures C9, medium pod apertures B4 and medium pod apertures C9 are by 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 more than medium pod apertures at medium pod apertures B4
Pressure at C9, because the internal diameter of spherical valve pocket 7 is slightly larger than the external diameter of spheroid 8, the internal diameter of general spherical valve pocket 7 is than the external diameter of spheroid 8
Big 1-2mm, the moment in the presence of medium power of spheroid 8 pushes core member C10 to so that runner B1 and runner C11 are blocked, gate valve
Lumen 14 is connected by runner A6 with runner B1, realizes releasing for the pressure of lumen 14；
Ibid principle, when runner E13 is upstream end, and runner D12 is downstream, pressure is more than Jie medium pod apertures C9 at
Pressure at matter pod apertures B4, the moment in the presence of medium power of spheroid 8 pushes core member B3 to so that runner B1 and runner C11
Block, the lumen 14 of gate valve is connected by runner A6 with runner C11, realizes releasing for the pressure of lumen 14.
