Description
technical field:
The utility model relates to one-way valve, particularly relates to a kind of one-way valve with elastic sealing structure.
background technique:
One-way valve mainly comprises the structures such as valve body, valve seat, spool, valve rod, valve gap, sleeve and filler assembly.Sleeve one-way valve in the market mostly can the sealing of visual cognitive ability between spool and valve rod, ensure in its sealability, but the sealing that have ignored between valve rod and valve gap, sealing between valve rod and valve gap adopts packing seal mostly, in packing seal Long-Time Service process, gap between filler and valve rod is increasing, and sealability can be deteriorated relatively, causes one-way valve shortening in working life.
model utility content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of one-way valve with elastic sealing structure, effectively can ensure the sealability of one-way valve, the work of stability and high efficiency in Long-Time Service process.
The technical solution of the utility model is as follows:
With the one-way valve of elastic sealing structure, comprise valve body, the two ends, left and right of valve body are respectively equipped with liquid entering hole and liquid outlet, it is characterized in that: in described body cavity, draw-in groove is slidably fitted with the valve seat of UNICOM's feed liquor and fluid cavity, the upper end of valve body is provided with valve gap, valve rod is slidably fitted with in valve gap, annular space is provided with between the upper semisection of valve gap and valve rod, from bottom to top filler baffle ring is installed successively in annular space, spring, lower liner, tetrafluoro filler, upper liner, Gland, the expansion cylinder that water swelling rubber is made also is provided with in the middle part of described tetrafluoro filler, the top of Gland is provided with the pressing plate be sleeved on valve rod, pressing plate and described valve gap upper-end surface are fixed by Stud connection part, the lower end of described valve rod is connected with the spool matched with valve seat.
The described one-way valve with elastic sealing structure, is characterized in that: the upper end outer wall of described valve gap is also combined with nut lock gripping members, and nut lock gripping members is positioned at the below of pressing plate.
The described one-way valve with elastic sealing structure, it is characterized in that: the shank of described spool is set with guide sleeve, guide sleeve is installed on the upper edge hole of valve body, the lower end surface of described valve gap is withstood in guide sleeve upper end, the lower end of guide sleeve is positioned at valve pocket, is tightly connected between guide sleeve and valve gap, valve body.
The utility model has the advantages that:
The utility model novel in structural design is reasonable, expansion cylinder is set up by setting up in spring and filler in the annular space between valve rod and valve gap, make tetrafluoro filler axially and radial direction tight, the installation good stability of valve seat, effectively can ensure the sealability of one-way valve, the work of stability and high efficiency in Long-Time Service process.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
