Fig. 1 is a kind of explosive view of relief valve, and Fig. 2 is the longitudinal section cross-sectional view after relief valve shown in FIG. 1 assembling.This is let out Pressure valve includes valve body 100 and spool 200, is equipped with valve chamber 110 in valve body 100, wherein spool 200 is placed in valve chamber 110, valve Core 200 includes the first spool 210 and the second spool 220.The water inlet line for being connected to the valve chamber 110 is provided in valve body 100 120, the outlet conduit 130 of the valve chamber 110 and the relief pipeline 140 for being connected to valve chamber 110 are connected to.
Referring to Fig. 3 and Fig. 4, when water inlet line 120 is intake, the first spool 210 and the second spool 220 described in hydraulic drives It moves synchronously to block the relief pipeline 140 and be connected to the water inlet line 120 and the outlet conduit 130;Referring to Fig. 5, When hydraulic pressure is greater than the specified pressure of the relief valve, 220 further movement of the second spool described in hydraulic drives is described to be connected to Water inlet line 120, outlet conduit 130 and relief pipeline 140, achieve the effect that pressure release;Referring to Fig. 6, when the water inlet line 120 When stopping water inlet, first spool 210 blocks the water inlet line 120 with 220 return of the second spool and is connected to institute Outlet conduit 130 and the relief pipeline 140 are stated, prevents siphonage.
Specifically, referring to fig. 2, water inlet line 120, relief pipeline 140 and outlet conduit 130 are respectively straight pipe The internal diameter of the pipeline in road, three is identical.Wherein, water inlet line 120 is arranged below relief pipeline 140, the water inlet line 120 Extending direction is parallel with the extending direction of the relief pipeline 140, for example, water inlet line 120 and relief pipeline 140 are along level Direction extends.First spool 210 and the second spool 220 are arranged along the vertical direction, with water inlet line 120 stop intake when, valve Core 200 can be in return under self gravity to block water inlet line 120 and be connected to outlet conduit 130 and relief pipeline 140.Water outlet The extending direction for extending perpendicularly to water inlet line 120 of pipeline 130, for example, water inlet line 120 is horizontally extending When, outlet conduit 130 extends along the vertical direction.
Referring to fig. 2, through-hole 211 is provided on the first spool 210, the second spool 220 can block the through-hole 211, normally When water inlet, the second spool 220 keeps blocking the state of the through-hole 211, and referring to Fig. 3 and Fig. 4, the cross section of the first spool 210 is big In the cross section of the second spool 220.Water is intake since in water inlet line 120, and water flow is pressing against the first spool 210 and passing through through-hole 211 press the second spool 220.When pressure is identical, pressure is directly proportional to cross section, due to the cross section of the first spool 210 Greater than the cross section of the second spool 220, thus the pressure acted on the first spool 210 be greater than act on the second spool 220 Pressure.The pressure of water can be by the picking-up synchronous with the second spool 220 of the first spool 210.
Referring to Fig. 1, relief valve further includes valve deck 300 and elastic component 310, and valve deck 300 includes the bonnet, 301 being fixedly connected With bottom flange 302, referring to fig. 2, the second spool 220 is slidably arranged between bonnet, 301 and bottom flange 302, the first spool 210 It is fixed on bottom flange 302, elastic component 310 is supported between bonnet, 301 and the second spool 220 so that the second spool 220 blocks Through-hole 211.It, when hydraulic pressure, which increases to pressure, can overcome the elastic force of elastic component 310, will be pushed away referring to Fig. 5 when hydraulic pressure increases Dynamic second spool, 220 compression elastic piece 310, i.e. the second spool 220 described in hydraulic drives are moved further up described in connection Water inlet line 120, outlet conduit 130 and relief pipeline 140.Referring to Fig. 6, when hydraulic pressure is decreased to less than the specified pressure of relief valve When, elastic component 310 extends first and drives the second spool 220 be repositioned to the second spool 220 blocks through-hole 211 again downwards.When When hydraulic pressure continues to be decreased to the stopping water inlet of water inlet line 120, the first spool 210 and the second spool 220 are whole under gravity Body falls and resets, and first spool 210 blocks the water inlet line 120 with 220 return of the second spool and is connected to The outlet conduit 130 and the relief pipeline 140.
Further, referring to Fig. 3, buffering pipe 150, buffering pipe are provided between water inlet line 120 and valve chamber 110 150 diameter is greater than the diameter of through-hole 211.Thus the water entered from water inlet line 120 is in addition to directly passing through through-hole 211 and second Spool 220 contacts outer, additionally it is possible to contact with the first spool 210, when intaking in this way, and be not up to the specified pressure of relief valve in hydraulic pressure Qiang Shi, water energy are enough stable by the first spool 210 jack-up synchronous with the second spool 220.Elastic component in one of the embodiments, 310 elastic force be greater than the first spool 210 and the second spool 220 total force, in this way water inlet when and hydraulic pressure not up to let out When the rated pressure of pressure valve, the first spool 210 and the second spool 220 can be synchronized to jack up always.The diameter of buffering pipe 150 is also Greater than the diameter of water inlet line 120, so make buffering pipe 150 uniformly certain balanced water pressure fluctuations the advantages of.
Further, referring to Fig. 3, valve chamber 110 further includes interconnected slow pressure chamber 111 and accommodating cavity 112, buffering pipe 150 are connected to the slow pressure chamber 111, and the outlet conduit 130 is connected to the slow pressure chamber 111, the relief pipeline 140 and institute State the connection of accommodating cavity 112.Slow pressure chamber 111 has bigger volume, has the ability of buffering water pressure fluctuations.
Further, referring to Fig. 1, valve body 100 includes upper cover 101 and lower cover 102, referring to Fig. 3, delays and presses 111 a part of chamber In upper cover 101, another part is arranged in lower cover 102 for setting, together with upper cover 101 is connected by screw to lower cover 102, so just In casting and forming, also facilitate the assembling of relief valve.Preferably, spool 200 is made of rubber material, can so increase spool 200 close leakproofness when each pipeline.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
