Abstract
The utility model discloses a defeated grey seal valve pneumatic valve connection structure, including first connecting rod, second connecting rod, round pin axle and axle sleeve, the round pin axle inserts set up downthehole on first connecting rod and second connecting rod, the axle sleeve cover is established at round pin off -axial end. This defeated grey seal valve pneumatic valve connection structure replaces original brass bushing with the roller bearing cover and as wear -resistant material, has reached the damage of avoiding the wearing and tearing of connecting rod hookup location structure and then leading to the fact the connecting rod, overall structure is simple, and the practicality is strong, and the security is high, easily uses widely.
Description
Technical field
This utility model relates to pneumatic operated valve attachment structure applied technical field, is specially a kind of defeated ash and seals valve pneumatic operated valve attachment structure.
Background technology
In water-tube boiler ash-transmission system application, pneumostop ball valve often occurs that bulb, pressing plate and Fructus Musae sealing ring are washed away by grey gas mixed airflow at a high speed, causes the situation of heavy wear.Accessory owing to damaging is more, needs integral replacing, costly, and above-mentioned situation occurred the most again less than three months every time time serious, and serious threat is to safety in production.
Through repeatedly in-situ processing, the former connecting rod junction that reason the is pneumatic means use pyrite copper sheathing of discovery fault is as high-abrasive material, but there is bigger friction between brass bushing and axle, and copper sheathing heavy wear after life-time service, time serious, mill leads to bar.Causing pneumatic means pneumatic bulb switch not in place, produce slit source ash, heat ash, under the effect of gases at high pressure, inside impact pneumatic means, and then damages the accessories such as whole seal ball-valve, pressing plate, rubber seal.
Utility model content
The purpose of this utility model is to provide a kind of defeated ash to seal valve pneumatic operated valve attachment structure, and it can effectively solve the problem that problem present in background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of defeated ash seals valve pneumatic operated valve attachment structure, including first connecting rod, second connecting rod, bearing pin and axle sleeve；Described bearing pin is inserted on first connecting rod and second connecting rod in the hole offered；Described axle sleeve is set in bearing pin outer end.
Further, described axle sleeve is ball bearing socket.
Compared with prior art, the beneficial effects of the utility model are: this defeated ash seals valve pneumatic operated valve attachment structure, replace original brass bushing as high-abrasive material with roller bearing sleeve, have reached the damage avoiding connecting rod link position structural wear in turn result in connecting rod；Overall structure is simple, practical, and safety is high, it is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of defeated ash seals valve pneumatic operated valve attachment structure, including first connecting rod 1, second connecting rod 2, bearing pin 3 and axle sleeve 4；Described bearing pin 3 is inserted on first connecting rod 1 and second connecting rod 2 in the hole offered；Described axle sleeve 4 is set in bearing pin 3 outer end.
Further, described axle sleeve 4 is ball bearing socket.
Of the present utility model when design: to use roller bearing sleeve to replace original brass bushing as high-abrasive material, reached the damage avoiding connecting rod link position structural wear in turn result in connecting rod；A large number of maintenance cost is saved by the company that is not only, and service work the most from now on opens brand-new innovation mode on " repairing the old and utilizing scraps, technology innovation ".
Embodiment the most of the present utility model, for the ordinary skill in the art, being appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can carry out multiple change, revise, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
