Abstract
The utility model discloses a hydraulic double pipelines explosion prevention valve which includes a valve body, a valve cavity, the valve body is provided with a first pipe port, a second pipe port, a third pipe port, the first pipe port is connected with the valve cavity by the first channel, the second pipe port is connected with the valve cavity by the second channel, the third pipe port is perpendicular to the valve cavity, the valve cavity is installed with an activity valve core, the diameter of the activity valve core is larger than that of the first channel and the second channel, the two ends of the activity valve core are sleeved with compressed springs. The hydraulic double pipelines explosion prevention valve of the utility model has the beneficial effects that the explosion prevention valve can not only be used as a one inlet and two outlets explosion prevention valve, when one hydraulic pipeline blasts, thereafter the explosion prevention valve automatically gags the hydraulic pipeline, so the hydraulic pipeline not blasted continues keeping unblocked to guarantee that the whole hydraulic system works normally. Furthermore the explosion prevention valve can be used as a two inlets and one outlet, a one inlet and one outlet explosion prevention valve.
Description
Technical field
The utility model relates to a kind of explosion-proof valve, especially relates to a kind of hydraulic dual circuit explosion prevention valve.
Background technique
In Iron And Steel Plant, machinery adopts hydraulic system in a large number, in case the explosion of hydraulic system pipeline, machinery must out of service the maintenance.For easy to maintenance after the pipeline explosion, employing often is equipped with explosion-proof valve on pipeline, at present, the pipeline explosion-proof valve characteristics of using in the prior art are: have only an import and an outlet, in case during the hydraulic pipe line explosion, its pipeline explosion-proof valve can be blocked hydraulic pipe line, prevent that the fluid in the hydraulic pipe line from rushing down outward, but use such explosion-proof valve, still needing hydraulic pipe line to quit work could keep in repair, and can't guarantee that hydraulic system continues normal operation, function singleness.
The model utility content
The utility model is to have only an import and an outlet in order to overcome explosion-proof valve of the prior art, function singleness, after the hydraulic pipe line explosion, can't guarantee the shortcoming that hydraulic pipe line works on, provide a kind of have multi-functional, therein after pipeline explosion, can keep in repair the explosion pipeline, the while can guarantee the hydraulic dual circuit explosion prevention valve that the hydraulic pipe line of not explosion works on.
For realizing above purpose, the utility model is achieved through the following technical solutions:
Hydraulic dual circuit explosion prevention valve, comprise valve body, valve pocket, valve body are provided with first interface tube, second interface tube, the 3rd interface tube, first interface tube communicates with valve pocket by first passage, and second interface tube communicates with valve pocket by second channel, the 3rd interface tube is vertical with valve pocket, movable spool is installed in the valve pocket, and the moving valve core diameter is greater than first passage and second channel diameter, and movable spool two ends are with pressure spring respectively.
Preferably, described valve body two ends are equipped with the valve end cap, and first interface tube and second interface tube are separately positioned on two valve end caps.
Preferably, installation activity spool in the described valve pocket has two steps on the movable spool, have through hole on the step.
Preferably, between described valve end cap and the valve body O-ring seals is installed.
Preferably, it is characterized in that, on the described valve body pressure measuring tie-in is installed.
Hydraulic dual circuit explosion prevention valve beneficial effect in the utility model is: both can be as the explosion-proof valve of one-in-and-two-out, therein after hydraulic pipe line explosion, can block the explosion pipeline automatically, the explosion pipeline can not continue to keep unimpeded, guarantees whole hydraulic system proper functioning.Can also advance one as two in addition goes out and the one-in-and-one-out explosion-proof valve.

Embodiment
Below in conjunction with accompanying drawing specific embodiment of the utility model is done a detailed description:
Referring to Fig. 1, Fig. 2, hydraulic dual circuit explosion prevention valve, comprise valve body 1, valve pocket 10, valve body 1 two ends are separately installed with valve end cap 2,12, valve end cap 2 is provided with first interface tube 11, valve end cap 12 is provided with second interface tube 13, valve end cap 1,12 and valve body between O-ring seals 8 is installed, can prevent hydraulic fluid leak, first interface tube 11 communicates with valve pocket 10 by first passage 14, second interface tube 13 communicates with valve pocket 10 by second channel 15, movable spool 3 is installed in the valve pocket 10, and movable spool 3 diameters are greater than the diameter of first passage 14 and second channel 15, and movable spool 3 has two steps 6, have through hole 7 on the step 6, movable spool 3 two ends are with pressure spring 5 respectively, and pressure spring 5 one ends are fixing by the step on the movable spool 6, and the other end is fixed on the valve end cap 2.Have three interface tube 4 vertical on the valve body 1 with valve pocket 10.Pressure measuring tie-in 9 is installed on the valve body 1, utilizes pressure measuring tie-in 9 to carry out pressure measurement to the hydraulic oil in the valve pocket 10 and detect.
As Fig. 1, Fig. 2, shown in Figure 3, during use, two valve end caps 2,12 are connected with hydraulic oil pipe respectively, and the 3rd interface tube 4 is connected with hydraulic oil pipe.Select the 3rd interface tube 4 as import, hydraulic oil enters in the dual circuit from valve end cap 2 through through hole 7; When pipeline explosion that valve end cap 2 one ends connect, the pressure difference of utilizing step 6 both sides of movable spools 3 in the valve pocket 10 to exist is pushed movable spool 3 to valve end cap 12 1 sides and is blocked second channel 15, and the explosion pipeline can not keep unimpeded.When selecting first interface tube 11 as the hydraulic oil import, hydraulic oil is pressed to valve end cap 12 with movable spool 3, blocks another second channel 15, the three interface tubes 4 and exports as hydraulic oil.Also can be simultaneously with first interface tube 11 and second interface tube 13 as import because there is the hydraulic oil of uniform pressure in two ends, movable spool 3 can keep balance, with the 3rd interface tube 4 as outlet.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
