Abstract
A combination special-form seal element belongs to the auxiliary component technical field of mechanical industry, which comprises a seal element body provided with a pressure support slot, wherein the top end of the pressure support slot is provided with two notches, a spring is provided in the pressure support slot and the notches. The combination special-form seal element is characterized in that the section of the seal element body (1) is in Y-shape, the pressure support slot (2) at the upper part is in U-shape, the notches are set as (4), (5), the spring is arranged in the pressure support slot (2) and the two notches (4, 5). Compared with the prior art, the combination special-form seal element has firm fixation of the spring and reasonable force on the lip, to avoid the separation between filled polytetrafluoroethylene and the metal spring under impact load. The combination special-form seal element has the advantages of simple installment and detachment.
Description
Technical field
Combined type Idiotype Sealing belongs to mechanical industry auxiliary element field.
Background technique
In recent years, along with the develop rapidly of science and technology, the innovation of manufacturing technology, equipment is maked rapid progress, must be suitable mutually with the special operation condition condition as the Sealing of mechanical movement auxiliary element.Traditional manufacturing mechanism and manufacturing process are seriously restricting the Sealing quality, and we see this situation by Zibo love section Sealing, introduce up-to-date production technology---no die numerical control processing and fabricating in the world today.Iron And Steel Company's rolling mill working condition is more abominable, and Sealing is required than higher, and the Sealing of traditional fabrication can not meet the demands, and owing to the wearing and tearing of cylinder body, accessory is also inapplicable at random, needs the enough elasticity of Sealing that surplus is arranged simultaneously.That is to say, need novel Sealing in the actual production.
The model utility content
The technical problems to be solved in the utility model is, overcome the problem that prior art exists, it is fixed to design a kind of spring, lip is stressed more reasonable, make Sealing can not fill poly-tetrafluoro when being subjected to impact load and separate with metal spring, installation and removal are combined type Idiotype Sealing eaily.
The technological scheme that its technical problem that solves the utility model adopts is: this combined type Idiotype Sealing, comprise on Sealing body, the Sealing body and have the pressure support groove, pressure support groove top is provided with bayonet socket, spring is installed in pressure support groove and the bayonet socket, it is characterized in that: the Sealing body section is " U " shape for " Y " shape upper pressure support slot 2, bayonet socket is a dual-mouth, and spring is installed in pressure support groove and two bayonet sockets.
The pressure support groove also can be designed to " V " shape, and the top is a dual-mouth.
Compared with prior art, the utility model combined type Idiotype Sealing advantage and good effect are:
The Sealing body section is " Y " shape, and bayonet socket is a dual-mouth, and spring is installed in pressure support groove and two bayonet sockets.Spring is fixed, and lip is stressed more reasonable, makes Sealing can not fill poly-tetrafluoro when being subjected to impact load and separates with metal spring.Installation and removal are more convenient, because be that dual-mouth is stressed, when Sealing was subjected to external force, spring stress was even.Satisfy the requirement of high standard sealing under the special operation condition condition, fill up the blank in manufacturing mechanism field.
Description of drawings
Fig. 1 is that the structure of the utility model combined type Idiotype Sealing is cutd open and shown schematic representation.It is most preferred embodiment of the present utility model.Wherein: 1 Sealing body, 2 pressure support grooves, 3 springs, 4,5 bayonet sockets.
Embodiment
Be described further below in conjunction with 1 pair of the utility model combined type of accompanying drawing Idiotype Sealing:
With reference to Fig. 1
At the seal request under the special operation condition condition, as steel rolling production-line, its temperature is about 250 ℃, pressure 70MPa, speed 5m/s, corrosive medium are strong etc., and requirement designs, and this combined type Idiotype Sealing is made up of Sealing body 1, pressure support groove 2, spring 3, bayonet socket 4,5.Sealing body 1 cross section is that " Y " shape upper pressure support slot 2 is " U " shape, and pressure support groove 2 tip designs are dual-mouth 4,5, and spring 3 is installed in pressure support groove 2 and the bayonet socket 4,5.Spring 3 adopts stainless steel to make, and Sealing body 1 adopts teflon to make.
According to design and equipment needs, pressure support groove 2 also can be designed to the structure that " V " shape etc. can well cooperate with spring, and the top is a dual-mouth.
During use, this combined type Idiotype Sealing is installed in desired area, realizes sealing.Because Cross section Design adopts two-sided bayonet socket 2, lip is stressed more reasonable, and spring 3 is fixed, makes Sealing can not fill poly-tetrafluoro when being subjected to impact load and separates with metal spring.Installation and removal are more convenient, because be that dual-mouth is stressed, when Sealing was subjected to external force, spring stress was even.
Claims (2)
1, combined type Idiotype Sealing, comprise on Sealing body, the Sealing body and have the pressure support groove, pressure support groove top is provided with bayonet socket, spring is installed in pressure support groove and the bayonet socket, it is characterized in that: Sealing body (1) cross section is " U " shape for " Y " shape upper pressure support slot (2), bayonet socket is dual-mouth (4), (5), and spring is installed in pressure support groove (2) and bayonet socket (4), (5).
2, combined type Idiotype Sealing according to claim 1 is characterized in that: pressure support groove (2) is " V " shape, and the top is dual-mouth (4), (5).
