Abstract
The utility model relates to an anti-explosion valve capable of verifying the anti-explosion effect for a hydraulic pump station, comprising an anti-explosion valve body which is connected with an oil return tank, the end part of the anti-explosion valve body is provided with an oil transportation port, and an electromagnetism ball valve is arranged on the oil line of the oil transportation port. The utility model has the beneficial effects that by additionally arranging the oil transportation port and the electromagnetism ball valve on the anti-explosion valve, oil can directly return to the oil return tank through the electromagnetism ball valve; when the setting effect of the anti-explosion valve needs to be verified, the electromagnetism ball valve can be opened after being powered on, the oil can directly return to the oil return tank through a large pipeline, the process be equivalent to the process of simulating the frature of an oil pipe; if the anti-explosion valve is set correctly, an anti-explosion core moves downwards, thus the oil line is closed; and if the anti-explosion valve is set incorrectly, the electromagnetism ball valve can be closed, and satisfied anti-explosion effect can be realized by testing repeatedly.
Description
Technical field
The utility model relates to a kind of explosion-proof valve, relates in particular to the explosion-proof valve that explosion-proof effect was used and can be verified to a kind of hydraulic power unit.
Background technique
When the hydraulic jack load-carrying moves up and down, if the oil pipe cracking, can make weight out of control and tenesmus at full speed is easy to lead to serious accident.For preventing this type of accident, usually at oil cylinder (referring to the chamber that drops) dress explosion-proof valve, but existing explosion-proof valve need be set throttling damping (differential pressure close value) according to conditions such as the oil cylinder movement velocity at scene and heavy burdens, and can't verify the actual effect of its setting; If set excessively, can cause sport efficiency to reduce, the fluid heating is big, even causes the oil cylinder can't proper functioning; If set too smallly, explosion-proof valve then lacks explosion-proof effect, exists the potential safety hazard of pipeline rupture.
The model utility content
At above defective, the utility model provides a kind of hydraulic power unit that helps improving explosion-proof effect, help verifying repeatedly to use and can verify the explosion-proof valve of explosion-proof effect, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
The explosion-proof valve of explosion-proof effect is used and can be verified to a kind of hydraulic power unit, comprises explosion-proof valve body, and explosion-proof valve body is connected with oil sump tank, and described explosion-proof valve end of body is offered an oil transportation mouth, on this oil transportation mouth place oil circuit Solenoid ball valve is housed.
Hydraulic power unit described in the utility model with and can verify that the beneficial effect of the explosion-proof valve of explosion-proof effect is: by on explosion-proof valve, setting up a hydraulic fluid port and Solenoid ball valve be housed, by the direct oil sump tank of this valve oil liquid; When needs checking explosion-proof valve is set effect, to open after Solenoid ball valve is charged, fluid can pass through the direct oil sump tank of large pipeline, is equivalent to the simulated oil tracheal rupture; If explosion-proof valve is set correct, this moment, explosion-proof spool promptly moved downward, and closed oil circuit; If set mistake, then can close solenoid valve, repetition test reaches till the satisfied explosion-proof effect always.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the inner connection diagram of explosion-proof valve that explosion-proof effect was used and can be verified to the described hydraulic power unit of the utility model embodiment.
Among the figure:
1, explosion-proof valve body; 2, Solenoid ball valve; 3, oil sump tank; 4, oil transportation mouth.
Embodiment
As shown in Figure 1, the explosion-proof valve of explosion-proof effect is used and can be verified to the described hydraulic power unit of the utility model embodiment, comprise explosion-proof valve body 1, explosion-proof valve body 1 is connected with oil sump tank 3, and an oil transportation mouth 4 is offered in described explosion-proof valve body 1 end, on these oil transportation mouth 4 place oil circuits Solenoid ball valve 2 is housed, when needs are verified the setting effect of explosion-proof valve, open after Solenoid ball valve 2 is charged, fluid can directly enter oil sump tank 3 by large pipeline, is equivalent to the simulated oil tracheal rupture; If explosion-proof valve is set correct, this moment, explosion-proof spool will move downward, and closed oil circuit; If it is not right to set, can close solenoid valve, repetition test reaches till the satisfied explosion-proof effect always.
