Accompanying drawing to be herein merged in manual and to form the part of this manual, shows the embodiment meeting the application, and is used from manual one principle explaining the application.
Detailed description of the invention
Also by reference to the accompanying drawings the application is described in further detail below by specific embodiment."front", "rear" described in literary composition, "left", "right", " on ", D score all with the laying state of the gate sealing system in accompanying drawing for reference.
The embodiment of the present application provides a kind of gate sealing system, comprise gate 1, P type weather strip 2, one way valve 3 and injection device 4, wherein, gate 1 is the core component of dam, is arranged in river course and can controls the water level of upstream river and the speed of downstream transport.P type weather strip 2 is arranged on the edge of gate 1, for the sealing between gate 1 and sealing part.
For different types of gate, P type weather strip 2 can have different set-up modes.As shown in Figure 1, if gate 1 is hinge movable dam, then P type weather strip 2 need are vertically arranged on the both sides of the edge of hinge movable dam; As shown in Figure 4, and if gate 1 is flashboard, then P type weather strip 2 needs take the shape of the letter U the parcel both sides of flashboard and bottom margin.
As shown in Fig. 2,3,5, be provided with cushion hole 20 in P type weather strip 2, in the related, the two ends of cushion hole 20 all communicate with the external world, and P type weather strip 2 obtains higher elastic module by cushion hole 20.And in the present embodiment, cushion hole 20 is set to closed structure, its inside is used for holding filler.Because the cushion hole 20 in correlation technique only has two ends to communicate with the external world, therefore only closed at both ends just can need be realized the integral sealing of cushion hole 20.The mode closing cushion hole 20 end is a lot, such as, block its open-ended realization sealing by rubber stopper, or close its port realization sealing by fluid sealant.
In the present embodiment, injection device 4 is communicated with by one way valve 3 with cushion hole 20, for injecting filler in cushion hole 20,3, one way valve can carry out unidirectional cutoff to infusion by cushion hole 20 process of flowing out, and the filler be injected into is remained within cushion hole 20.Injection device 4 can directly be connected with wherein one end of cushion hole 20, this eliminates the trouble arranging connecting hole in addition.For the ease of operation, injection device 4 is preferably connected with the side, top of cushion hole 20.And for the gate 1 of flashboard type, because P type weather strip 2 takes the shape of the letter U, therefore the two ends of cushion hole 20 are all positioned at top, and now injection device can be connected with any one end.
For the ease of injecting, filler is generally the better gas of mobility or liquid, such as air, water, hydraulic pressure wet goods.According to the kind of filler, injection device 4 selects corresponding gas injection apparatus or fluid infusion apparatus.
When there are wearing and tearing in the O shape sealing surface of P type weather strip 2, utilize injection device 4 to inject filler in cushion hole 20, filler can support large cushion hole 20, and then O shape sealing surface is expanded outwardly, and and be restored to sealing state between sealing part, thus avoid the generation of drainage.Operate very easy.
Because P type weather strip 2 does not need to carry out injection operation at any time, so there is no necessary injection device 4 be kept connection status with cushion hole 20 at any time, only need when needs inject filler, the two to be connected.Therefore, gate sealing system in the present embodiment is also provided with joint 5, joint 5 is arranged on P type weather strip 2, and be positioned at the side of one way valve 3 away from cushion hole 20, joint 5 is communicated with cushion hole 20, injection device 4 can be connected with joint 5 when needed, and injection device 4 can be separated with joint 5 after injection.Joint 5 can adopt quick connector etc. to realize quick linkage function.
As shown in Fig. 2,3,5, in order to simplify structure, joint 5 and one way valve 3 integratedly can be set to one-way valve type piecing, namely one way valve 3 are integrated in the inside of joint 5, can simplify external structure like this, be convenient to assembling work.On the outer peripheral face of one end of one-way valve type piecing, the outer peripheral face of namely one end of joint 5 is provided with pawl 50, this end of one-way valve type piecing extend in cushion hole 20, pawl 50 can with cushion hole 20 inwall close contact, to realize the fixing and function that is tightly connected.In addition, the projection 52 with two-way spigot surface also can be set at the other end of joint 5, when this end of joint 5 extend into the inside of such as device 4, protruding 52 can with the inwall close contact of injection device 4, realize sealing function.And when when plugging such as device 4, the spigot surface of protruding 52 can play again guide effect, prevent projection 52 and injection device 4 stuck.
In the present embodiment, one-way valve type piecing directly can adopt the I type one-way valve type piecing of straight tube-like, and this structure is comparatively simple, and cost is lower.But because the top of joint 5 with cushion hole 20 is connected, as shown in Figure 2, if adopt I type one-way valve type piecing, the bearing of trend of joint 5 also keeps consistent with cushion hole 20, then the outer end of joint 5 can be caused too high, cause joint 5 inconvenient with the connection of injection device 4.Therefore, as shown in Fig. 3,5, adopt L-type one-way valve type piecing in the present embodiment, be more convenient to attended operation.
As shown in Figure 4, for the gate 1 of flashboard type, because the length of cushion hole 20 is longer, and the middle part that there is bending, therefore may cause the partial occlusion of cushion hole 20.Once partial occlusion occurs cushion hole 20, when only having one joint 5, obstructive position may face the problem injecting difficulty away from a section of joint 5, cause sealing effectiveness to recover.In order to tackle this situation, in the present embodiment, an one way valve 3 and a joint 5 are respectively set at the two ends of the cushion hole 20 of U-shaped, when assigned address cannot be arrived by the filler that wherein one end is injected, injection device 4 can be connected with the joint 5 of the other end, make filler be injected by the other end and arrive assigned address, thus improve the reliability of gate sealing system.
The gate sealing system that the present embodiment provides effectively can avoid the generation of drainage, and structure is simple, and integrated level is high, simple operation, reliability are strong.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for a person skilled in the art, the application can have various modifications and variations.Within all spirit in the application and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the application.
