Abstract
The utility model provides a big lid of rotary valve seals packing, relates to a sealed packing, is equipped with outstanding piece (4) in the one end of packing (2), is equipped with recess (5) at the other end of packing (2), outstanding piece (4) and recess (5) is the phase -match structure, packing (2) form the annular structure after outstanding piece (4) and recess (5) contacts, outer fringe face in packing (2) of formation annular structure is equipped with cell body (3), sealing washer (1) and cell body (3) contacts, the utility model discloses a seal structure who uses the packing to encrypt the seal realizes the sealed of rotary valve and end cover, makes the rotary valve and the sealing performance of end cover improve by a wide margin, has reached the purpose that reduces the spillage of the interior dust of rotary valve.
Description
[technical field]
The utility model relates to a kind of sealed packing, especially relates to the large lid sealed packing of a kind of rotary valve.
[background technique]
Rotary valve equipment is the equipment that chemical industry production dust-like material often needs to use, generally adopted the aramid fiber material filler from cutting during rotary valve end bracket enclosed in the past, it is very inconvenient to install, filler and rotor are due to long contact friction after running a period of time, and filler there will be wearing and tearing in various degree, and without self-compensating property, along with the lengthening of service time, leakage rate strengthens gradually, and sealing effect progressively declines, and causes very large material from leakage.
[summary of the invention]
In order to overcome the deficiency in background technique, the utility model discloses the large lid sealed packing of a kind of rotary valve, the sealing of rotary valve and end cap is realized by the sealing configuration using packing to add seal ring, the sealability of rotary valve and end cap is significantly improved, reaches the object of the leakage rate reducing dust in rotary valve.
In order to realize described goal of the invention, the utility model adopts following technological scheme:
The large lid sealed packing of a kind of rotary valve, comprise seal ring and packing, projecting block is provided with in one end of packing, groove is provided with at the other end of packing, described projecting block and groove are the structure that matches, described packing forms ring structure after projecting block and groove contact, and be provided with cell body at the outer edge surface of the packing forming ring structure, described seal ring and cell body contact.
The large lid sealed packing of described rotary valve, the number of described cell body is at least one, and when cell body is multiple, multiple cell body interval is arranged.
The large lid sealed packing of described rotary valve, described seal ring and cell body are the structure that matches.
The large lid sealed packing of described rotary valve, the material of described packing is tetrafluoro.
The large lid sealed packing of described rotary valve, the material of described seal ring is elastic caoutchouc.
Owing to have employed technique scheme, the utility model has following beneficial effect:
The large lid sealed packing of rotary valve described in the utility model, the sealing of rotary valve and end cap is realized by the sealing configuration using packing to add seal ring, the sealability of rotary valve and end cap is significantly improved, when after packing wearing and tearing, projecting block and groove can provide surplus again, seal ring still can keep the sealing effect of packing by its elasticity, reaches the object of the leakage rate reducing dust in rotary valve; The utility model possesses the features such as structure is simple, practical, easy for installation rationally, wide market.

In figure: 1, seal ring; 2, packing; 3, cell body; 4, projecting block; 5, groove.
[embodiment]
Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples, and open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model;
The large lid sealed packing of rotary valve by reference to the accompanying drawings described in 1 ~ 4, comprise seal ring 1 and packing 2, the material of described packing 2 is tetrafluoro, the material of described seal ring 1 is elastic caoutchouc, projecting block 4 is provided with in one end of packing 2, groove 5 is provided with at the other end of packing 2, described projecting block 4 and groove 5 are the structure that matches, described packing 2 forms ring structure after projecting block 4 and groove 5 contact, cell body 3 is provided with at the outer edge surface of the packing 2 forming ring structure, the number of described cell body 3 is at least one, when cell body 3 is multiple, multiple cell body 3 interval is arranged, described seal ring 1 and cell body 3 contact, described seal ring 1 and cell body 3 are the structure that matches.
Implement the large lid sealed packing of rotary valve described in the utility model, the ring structure formed after being contacted according to projecting block 4 and groove 5 by packing 2 is socketed on the rotor of rotary valve, on the cell body 3 that outer edge surface seal ring 1 being socketed in the packing 2 forming ring structure is provided with, after rotary valve uses packing 2 to wear and tear for a long time, projecting block 4 and groove 5 can provide surplus again, and seal ring 1 still can keep the sealing effect of packing 2 by its elasticity.
The non-detailed portion of the utility model is prior art.
