Abstract
The utility model discloses a one way valve for fluid injection, which belongs to the one way valve for fluid injection on pipelines of pipe jacking tunnelling machines. The utility model is characterized in that inner rings of a valve body are provided with steps; the middle part of the inner rings is provided with pressing stripes which are matched with valve plates; two sides of the pressing stripes are provided with fixing holes which are mutually fixed with the valve plates; the middle part of the valve plates is provided with a reinforcing rib; two sides of the reinforcing rib are in a semicircle shape; the middle part of the reinforcing rib is respectively provided with concave mouths; the valve plates contact with the valve body on steps, and the one-way opening is formed. The utility model is suitable for high-pressure occasions.
Description
The utility model relates to the pipe-jacking technology field in the civil construction, belongs to the pipe jacking tunnelling machine and the interior a kind of row's grouting one way valve of duct wall that cut the soil body specifically.
The one way valve that is provided with in pipe jacking tunnelling machine and duct wall at present is membrane flap type, can not be used for high hydraulic pressure, meets the occasion of high pressure, and one way valve is easily washed out by the earth slurries, and the slurries that injected in the anti-pipeline in pipe jacking tunnelling machine soil cabin are difficult for discharging simultaneously, can influence effectiveness.
The purpose of this utility model provides a kind of can reach the interior slurries of pipeline in the pipe jacking tunnelling machine cabin and discharge smoothly, and extraneous slurries can entering the grouting one way valve in cabin and the pipeline under the high pressure occasion.
For finishing the technical scheme that above-mentioned purpose adopts: step is set in the valve body, the centre is provided with the press strip that is cooperated with valve block, the fixing hole that interfixes with valve block is established in the press strip both sides, pass through bolt, the valve block that is provided with in the valve body, centre are that reinforcing rib both sides respectively are semicircle, and valve block is contacted with on the step of valve body, screw thread is established in the valve body outside, is used to be installed in development machine and the duct wall.
The utility model is owing to fix with the valve body press strip in the middle of the valve block, and the semicircle sheet in both sides can unidirectionally be opened, and discharges in the cabin so the slurries energy is unidirectional, and can use in the high pressure occasion, and reliability is better.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structure sectional view;
Fig. 2 is the utility model structure chart.
According to illustrated in figures 1 and 2, valve body 3 inner rings are provided with step 4, the centre is provided with the press strip 6 that is cooperated with valve block 2, wrench when this press strip 6 can be used as one way valve and is screwed into or screws out, the fixing hole 7 that interfixes with valve block 2 is established in press strip 6 both sides, by bolt 1 valve body 3 and valve block 2 are interfixed, above-mentioned valve block 2 usefulness polypropylenes are made, and the centre is a reinforcing rib 8, and reinforcing rib 8 both sides are semicircle, respectively there is a recess 9 centre, valve block is opened easily, and valve block 2 is contacted with on the step 4 of valve body 3, draws into unidirectional Push And Release, screw thread 5 is established in valve body 3 outsides, is used to be installed on the side of development machine and the duct wall use.
