Description
Technical field
The utility model belongs to mechanical assembly technique field, and in particular to one kind is pulled out for self-sealing check-valves self-sealing stone roller
Device out.
Background technique
Nuclear power station self-sealing check-valves is acted on due to long-play by high temperature and pressure, in breakdown maintenance, is existed certainly
The case where more difficult extraction, is cut or polish jade with an emery wheel in sealing.General way is to pound self-sealing stone roller downwards using copper rod, then takes out six directions ring, recycles
Lifting lug is screwed into the threaded hole of self-sealing stone roller, pulls out self-sealing stone roller by suspender belt and chain block, but since copper rod can only be pounded from close
The phenomenon that envelope stone roller edge, there are discontinuity, is not easy to cut or polish jade with an emery wheel self-sealing sometimes and pound down, cannot smoothly take out six directions ring, separately
Self-sealing cannot be cut or polish jade with an emery wheel sometimes through this method and smoothly be pulled out outside, the reason is that suspender belt is flexible, while limited valve on site
Door installation space, very multipoint valve installation site is bad, and narrow space is not available suspender belt and chain block.This method
The self-sealing stone roller disassembly problem of self-sealing check-valves cannot be carried out well.
Summary of the invention
The technical issues of the utility model solves:
In view of the deficiencies of the prior art, the utility model provides a kind of extract for self-sealing check-valves self-sealing stone roller and fills
It sets, solves the problems, such as that the bad equal working spaces of self-sealing check-valves installation site are limited.
The technical solution adopted in the utility model:
One kind cutting or polish jade with an emery wheel extracting apparatus, including snap ring one, snap ring two, fastening bolt, support for the self-sealing of self-sealing check-valves
Arm, snap ring one and snap ring two are semicircle, and snap ring one is crossed fastening bolt with snap ring two-way and is fixedly connected, snap ring one and snap ring two
Side wall be equipped with threaded hole, support arm is fixedly mounted on the side wall of snap ring one and snap ring two by bolt and threaded hole.
The middle position of the support arm is equipped with self-sealing stone roller and extracts bolt, and self-sealing stone roller extracts bolt under support arm
Side has back of the body cap.
The utility model has the beneficial effects that
(1) the utility model provides a kind of for self-sealing check-valves self-sealing stone roller extracting apparatus, and structure is simple, uses
It is convenient；
(2) the utility model is designed using self-sealing check-valves original structure, the threaded hole cut or polish jade with an emery wheel by self-sealing,
It is cut or polish jade with an emery wheel using under screw top with extraction self-sealing；
(3) the utility model provides a kind of small in size for self-sealing check-valves self-sealing stone roller extracting apparatus, the work needed
Industry space is small, can effectively solve the problems, such as that the bad equal working spaces of self-sealing check-valves installation site are limited.
Detailed description of the invention
Fig. 1 provides a kind of for self-sealing check-valves self-sealing stone roller extracting apparatus structural schematic diagram for the utility model；
In figure: 1. snap rings one, 2. snap rings two, 3. fastening bolts, 4. support arms, 5. self-sealings stone roller extract bolt.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the utility model, which provides one kind, cuts or polish jade with an emery wheel extracting apparatus, including snap ring for the self-sealing of self-sealing check-valves
One 1, snap ring 22, fastening bolt 3, support arm 4, self-sealing stone roller extract bolt 5, and snap ring 1 and snap ring 22 are semicircle, card
Ring 1 is fixedly connected with snap ring 22 by fastening bolt 3, and the side wall of snap ring 1 and snap ring 22 is equipped with threaded hole, support arm
4 are fixedly mounted on the side wall of snap ring 1 and snap ring 22 by bolt and threaded hole, and self-sealing stone roller extracts bolt 5 and is mounted on branch
The middle position of brace 4, self-sealing stone roller extract bolt 5 and have back of the body cap on the downside of support arm 4.
The working principle of the utility model are as follows:
Extraction bolt 5 is cut or polish jade with an emery wheel in self-sealing to be screwed into the upper corresponding threaded hole of self-sealing stone roller.Tightening 4 downside back of the body cap of support arm makes
Self-sealing stone roller extracts 5 stress of bolt, then proceedes to rotation back of the body cap, and pressure self-sealing stone roller removes six directions ring until six directions ring loosens
Afterwards, release 4 downside back of the body cap of support arm is extracted bolt 5 using the nut fastening self-sealing stone roller of 4 top of support arm, is pulled upwardly certainly
Sealing stone roller makes self-sealing stone roller leave valve body, completes the disassembly of self-sealing stone roller.
The utility model is explained in detail above in conjunction with drawings and examples, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of make a variety of changes.The prior art can be used in the content being not described in detail in the utility model.
