Abstract
The utility model relates to a horizontal one-way valve for pulp. The horizontal one-way valve for the pulp comprises a valve body, a spring seat, a valve piece, a valve seat and a spring. The spring seat and the valve seat are respectively fixedly arranged in the valve body, the valve piece is contacted and connected with the valve seat, the spring is connected with the valve piece and the spring seat, and a hole passage is arranged in the middle of the valve seat. The horizontal one-way valve for the pulp can stably exert a function of one-way stopping in a horizontally arranged pipeline horizontally arranged on a pulp injection pump, and is simple in structure, reliable, and easy to realize.
Description
Technical field
The utility model relates to the horizontal one-way valve of a kind of slurry.
Background technique
In grouting pump, usually adopt non-return valve, and all be arranged in the vertical pipeline, yet for the dual-fluid synchronous slip casting pump that has adopted double-acting cylinder, the one-way valve of level need to be set, non-return valve can not be stablized owing to off-centre the function of its unidirectional cutoff of performance when horizontal positioned.Therefore need a kind of one-way valve that under horizontal service position, still can stablize operation.
Summary of the invention
The utility model purpose is to address the above problem, and a kind of horizontal one-way valve of slurry that can still can stablize operation under horizontal service position is provided, and is specifically realized by following technological scheme.
The horizontal one-way valve of a kind of slurry, this slurry comprises valve body, spring seat, valve block, valve seat and spring with horizontal one-way valve, described spring seat and valve seat are fixedly installed on respectively in the valve body, described valve block is connected with the valve seat contact, described spring connects described valve block and described spring seat, and described valve seat middle part is provided with the duct.
The horizontal one-way valve of described slurry, it further designs and is that the surface of contact of described valve block and valve seat is conical surface shape, and described valve body is provided with a notch, and described surface of contact connects described duct and notch.
The utility model can be stablized the function of performance unidirectional cutoff in being horizontally set on the horizontally disposed pipeline of grouting pump, and simple and reliable for structure, is easy to realize.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is further specified.
This slurry comprises valve body 1, spring seat 2, valve block 3, valve seat 4 and spring 5 with horizontal one-way valve, spring seat 2 and valve seat are fixedly installed on respectively in the valve body and both are relative, valve block is connected with the valve seat contact, and spring connects valve block and spring seat, and the valve seat middle part is provided with duct 41.Be provided with the pressure piece 6 that send valve block for the top in the duct, the surface of contact of valve block and valve seat is conical surface shape, and valve body 1 is provided with a notch 11, and surface of contact connects duct 41 and notch 11.
During operation, when the duct slurry pressure was higher than notch pressure, spool was backed down by slurry, so that the slurry in the duct flow to notch; When slurry when the pressure of notch is higher than in the duct slurry pressure, this moment is because the surface of contact of valve block and valve seat is conical surface shape, valve block still can be connected with the valve seat contact under the pressure of spring and slurry exactly, so that slurry can not flow to the duct from notch, thereby realizes unidirectional cutoff function.
The utility model can be stablized the function of performance unidirectional cutoff in being horizontally set on the horizontally disposed pipeline of grouting pump, and simple and reliable for structure, is easy to realize.
Claims (2)
