Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Embodiment 1
As shown in figure 1, the present embodiment protects a kind of anti-vacuum relief valve, the anti-vacuum relief valve includes being provided with The valve body 2 of inner chamber 1, include inlet 3 and liquid outlet 4 on valve body 2, be provided with the side wall of valve body 2 with The air ventilation passage and fluid flow paths that inner chamber 1 connects, interior be provided with of air ventilation passage control its opening and closing The anti-component of vacuum valve element 5, the component of pressure releasing valve core 15 for controlling its opening and closing is provided with fluid flow paths.
The anti-vacuum relief valve, anti-vacuum function and decompression function are combined on a valve body 2, overcome It is complicated that installation procedure existing for anti-vacuum valve and relief valve is installed respectively in the past, leak source caused by joint is more is more The problem of, and reduce the number of valve, cost is saved, while the anti-vacuum relief valve can prevent heat The water tank of hydrophone is taken out flat because negative pressure is excessive, and can prevent from causing water because internal liquid pressure is excessive Case bursts.
Lower mask body introduces the concrete structure of anti-vacuum core assembly and pressure releasing valve core component in the present embodiment.
As shown in figure 1, anti-vacuum core assembly includes anti-vacuum valve element 5 and anti-vacuum spring 6, gas circulation It is respectively equipped with the side wall at passage both ends to first annular raised 7 radially extended and the second annular protrusion 8, the One annular protrusion 7 is away from inner chamber 1, and when air ventilation passage circulates without gas, anti-vacuum valve element 5 is resisted against On one annular protrusion 7, anti-one end of vacuum spring 6 is connected on anti-vacuum valve element 5, and the other end is connected to In second ring projection 8.Air ventilation passage is by the gas stream that is opened up in the side wall of valve body 2 in present embodiment The anti-vacuum valve seat 9 of through hole 10 and installation on the side wall is formed, and the anti-vacuum valve seat 9 is away from valve body 2 The inwall of one end is provided with first annular raised 7 and cooperated with valve element, the diameter of above-mentioned gas opening 10 Less than the internal diameter of valve seat, so the side wall of valve body 2 of the border of gas communication hole 10 forms the second annular protrusion 8.
The first guide rod 11 is connected with anti-vacuum valve element 5, the first guide rod 11 passes through first annular raised 7, It is oriented to by movement of first guide rod 11 to anti-vacuum valve element 5, ensures that the anti-vacuum valve element 5 moves Stabilization, prevent failure.
O-ring seal 12 is provided with close to first annular raised 7 side on anti-vacuum valve element 5, for anti-true Sealing is formed between empty valve element 5 and first annular raised 7, prevents from leaking under normal circumstances.
As shown in figure 1, pressure releasing valve core component includes pressure release nut 13, pressure release spring 14 and pressure releasing valve core 15, One end side wall of the fluid flow paths close to inner chamber 1 is provided with to the 3rd annular protrusion 16 radially extended, is let out Pressure nut 13 is threaded in the one end of fluid flow paths away from inner chamber 1, when aneroid in fluid flow paths When body circulates, pressure releasing valve core 15 is resisted against on the 3rd annular protrusion 16, and the one end of pressure release spring 14, which is connected to, lets out On pressure valve core 15, the other end is connected on pressure release nut 13.Wherein, pressure release nut 13 can adjust and the The distance between three annular protrusions 16 so that the pressure releasing valve core component realizes the pressure release under different liquids pressure.
The second guide rod 17 is connected with pressure releasing valve core 15, the second guide rod 17 passes through the 3rd annular protrusion 16, Second guide rod 17 is that pressure releasing valve core 15 play the guiding role, and ensures the stabilization in the moving process of pressure releasing valve core 15. Pressure releasing valve core 15 is provided with O-ring seal 12 close to the side of the 3rd annular protrusion 16 so that pressure releasing valve core 15 with Sealing is formed between 3rd annular protrusion 16, prevents from leaking under normal circumstances.
When occurring negative pressure in water tank, due to the suction inside valve body 2, the anti-forced compression of vacuum valve element 5 is prevented Vacuum spring 6, anti-vacuum spring 6 shorten so that occur between anti-vacuum valve element 5 and first annular raised 7 Gap, extraneous air is entered in the anti-vacuum relief valve by air ventilation passage, and then enters water tank, Keep the pressure in water tank will not be too small, it is therefore prevented that water tank is taken out flat;When the pressure in water tank is excessive, by In the effect of fluid pressure, pressure releasing valve core 15 receives pressure, and compression pressure release spring 14, pressure release spring 14 contracts It is short, occur gap between the annular protrusion 16 of pressure releasing valve core 15 and the 3rd, the liquid in water tank is by liquid communication Passage is discharged to outside, reduces the pressure inside water tank, it is therefore prevented that water tank bursts.
Embodiment 2
The present embodiment and the difference of embodiment 1 are, non-return valve core component is additionally provided with inner chamber 1.
As shown in Fig. 2 non-return valve core component includes bearing pin 18 and baffle plate 19, the upper end of baffle plate 19 is provided with pin Hole, the upper end of baffle plate 19 are fixed on valve body 2 by bearing pin 18, and the lower end of baffle plate 19 is free end, gear The side wall of the inner chamber 1 of the upstream of plate 19 is provided with fourth annular projection 20, for limiting the rotation of baffle plate 19. When there is normal liquid to be flowed from inlet 3 to liquid outlet 4 in the valve body 2, baffle plate 19 is in working fluid In the presence of, lower end is lifted, liquid outflow, when liquid stops outwards flowing, and has backflow, the gear Plate 19 is because Action of Gravity Field lower end falls, and because the effect of withdrawing fluid is resisted against fourth annular projection 20 On, the flowing of liquid in inner chamber 1 is blocked, prevents excess pressure to be back to water tank and water tank is burst.Preferably, O-ring seal 12 is provided with close to the side of fourth annular projection 20 on baffle plate 19, ensures baffle plate 19 and the 4th Sealing is formed between annular protrusion 20 to coordinate.
