Specific embodiment
We are described further a kind of split type valve cage structure described in the utility model in conjunction with attached drawing below.
As shown in Fig. 1 to Fig. 5, a kind of split type valve cage structure of the present embodiment, including it is sequentially connected from the bottom to top
Valve body 1, valve deck 2, mounting rack 3, executing agency 4 are equipped with valve cage structure 5, the valve cage structure 5 between the valve body 1 and valve deck 2
Including split type valve cage 51 and valve seat 52, the top of the valve cage 51 is equipped with the first through hole 511 of connection valve rod 6, the valve
The side of cage 51 is equipped with deflector hole 512, the spool 7 of connection valve rod 6 is equipped in the valve cage 51, the bottom of the valve cage 51 is equipped with
Cage mouth 513, the valve seat 52 are equipped with the second through-hole 521 of connection valve cage 51, and the top of the valve seat 52 is equipped with position limiting convex ring
522, the inside of the position limiting convex ring 522, which is equipped with, reinforces annular groove 523, and heap is welded with STL alloy seal ring in the reinforcement annular groove 523
524, the inside of the STL alloy seal ring 524 is equipped with the sealing slope 525 of corresponding valve core sealed cover 71.The position limiting convex ring
522 top is equipped with cricoid auxiliary seal step 526.The cross section of the auxiliary seal step 526 is trapezium structure, and auxiliary
The minimum diameter of sealed step 526 is helped to be less than or equal to the internal diameter for reinforcing annular groove 523.The inside of the auxiliary seal step 526
Auxiliary seal slope 527 equipped with corresponding valve core sealed cover 71.The outside of the auxiliary seal step 526 is equipped with fixed rubber pad
528.The top of the auxiliary seal step 526 is equipped with sealing rubber pad 529.
The service condition of the valve cage structure is as follows: when installation, first valve seat 52 being packed into valve body 1, then again by valve cage 51
Be packed into so that cage mouth 513 corresponds to position limiting convex ring 522, then after spool 7 and valve rod 6 are inserted into valve deck 2, by bolt by valve deck 2 with
Valve body 1 is connected and fixed, and valve cage 51 and valve seat 52 are compressed.
Fluid flows through valve core sealed cover 71 and STL alloy seal ring from the second through-hole 521 after the entrance of the inlet opening of valve body
Then 524 contact position flow to the upper inner cavity of valve body 1 by deflector hole 512, finally flowed out by the apopore of valve body.In valve
When core sealing surface 71 and 52 gap of valve seat are smaller, the flow velocity of fluid quickly increases, and biggish impact is caused to valve seat 52, due to heap
STL alloy seal ring 524 has been welded, to effectively enhance impact resistance, has extended the service life of valve seat 52.And pass through
Auxiliary seal step 526 is set on position limiting convex ring 522, since the minimum diameter of auxiliary seal step 526 is less than or equal to limit
The internal diameter of position bulge loop 522, and it is provided with the auxiliary seal slope 527 of corresponding valve core sealed cover 71, therefore, in STL alloy seal
Ring 524 does not receive in the case that larger abrasion is unable to complete sealing, and auxiliary seal step 526 not will receive that fluid is too big to be rushed
It hits, the backup seal structure after can be used as STL alloy seal ring 524 and can not working further extends making for valve cage structure
Use the service life.Fixed rubber pad 528 can reduce the technology processing request of auxiliary seal step 526, convenient for valve cage 51 and valve seat 52
Connection, sealing rubber pad 529 be used for cooperate valve core sealed cover 71 complete valve closure.Pass through point of valve cage 51 and valve seat 52
It is difficult to reduce technology convenient for the machining of the second through-hole 521 and the completion of built-up welding STL alloy seal ring 524 for the combination of body formula
Degree.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
