The harsher pipe-line system of the operating mode such as compressor and mammoth pump in large-scale ethylene plant, it is desirable to from quick closedown, compared with low pressure loss
And the check-valves of noise, especially gas phase media, it is necessary to using special shape axial flow type check valve, to ensure above-mentioned pipeline system
System safely and effectively operation.Current axial flow type check valve guide sleeve is easily blocked by solid particle, causes check-valves to open
Or close, and medium easily forms eddy flow after valve opening, and destruction is produced to the inner body of valve.
Utility model content
In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of axial-flow type is provided
Check-valves.
The purpose of this utility model is achieved through the following technical solutions：A kind of axial flow type check valve, including valve body,
The supporting part and valve element being arranged in valve body；It is characterized in that：Valve element includes the flap and guide sleeve being fixedly connected；The support
Portion is provided with through hole, and one end of through hole is fixed with end cap, and guide sleeve is slidably arranged in through hole through the through hole other end, guide sleeve
The spring being inside provided between flap and end cap, the cylindrical of guide sleeve are fixed with distance collar and cleaning between through-hole wall
Ring, distance collar is between wiper ring and end cap；The valve interior wall is circumferentially arranged to be had between flap and supporting part
Gusset, gusset extend to the cylindrical of flap from valve interior wall.
Preferably, the supporting part is structure as a whole with valve body.
Preferably, the gusset is evenly arranged with multiple.
Preferably, the gusset is structure as a whole with valve body.
Preferably, mandrel is provided with the spring, one end of mandrel is fixed on end cap, and the length of mandrel is less than spring
Length.
The beneficial effects of the utility model are：
First, wiper ring, which can strike off, is attached to the cylindrical impurity of guide sleeve, prevents impurity enters from blocking bullet in guide sleeve
Spring so that valve element can not be slided smoothly, cause check-valves to open or close；
2nd, the medium channel in valve pocket can be divided into multiple by gusset, and after valve is opened, medium flows from multiple medium channels
Go out, eddy flow will not be produced, avoid damage of the eddy flow to valve internal part, extend the service life of valve.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the scope of protection of the utility model is not limited to
It is as described below.
As shown in Fig. 1 ~ 4, a kind of axial flow type check valve, including valve body 1, the supporting part 2 and valve element 3 that are arranged in valve body 1；
It is characterized in that：Valve element 3 includes the flap 4 and guide sleeve 5 being fixedly connected；The supporting part 2 is provided with through hole 6, and the one of through hole 6
End is fixed with end cap 7, and guide sleeve 5 is slidably arranged in through hole 6 through the other end of through hole 6, is provided with guide sleeve 5 positioned at flap
Spring 8 between 4 and end cap 7, distance collar 9 and wiper ring 10, spacing are fixed between the inwall of cylindrical and through hole 6 of guide sleeve 5
Ring 9 is between wiper ring 10 and end cap 7；The inwall of valve body 1 is circumferentially arranged to be had between flap 4 and supporting part 2
Gusset 11, gusset 11 extend to the cylindrical of flap 4 from the inwall of valve body 1, and valve pocket is divided into multiple runners, prevent medium from forming rotation
Stream.
Using being welded to connect between flap 4 and guide sleeve 5, using being welded to connect between wiper ring 10 and supporting part 2, clean
The end face of ring 10 flushes with the left end of supporting part 2.
The supporting part 2 is structure as a whole with valve body 1, and gusset 11 is structure as a whole with valve body 1, casting integrated shaping；Muscle
Plate 11 is evenly arranged with multiple, and such as Fig. 3, preferable gusset 11 is provided with three；It is provided with mandrel 12 in spring 8, the one of mandrel 12
