Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the capsule cover, specifically point to a kind of full-closed type floating disc PU capsule cover. BACKGROUND

[0002] Capsule cover, as a kind of elastic sealing structure, is widely used in industrial equipment, especially in full-closed type floating disc plays a key role, capsule cover is usually made of wear-resistant, aging-resistant material, its inside can be filled with gas or liquid, to realize the support and sealing of floating disc.

[0003] However, the existing floating disc capsule cover has significant deficiencies in sealing, due to improper material selection, manufacturing process limitations or long-term use of wear and tear, the sealing performance of the capsule cover often cannot reach the ideal state, which leads to the problem of medium leakage in the use process of floating disc, not only affects the normal work of floating disc, but also may cause pollution to the surrounding environment. INVENTION CONTENTS

[0004] In order to solve the above problems, the utility model provides a kind of full-closed type floating disc PU capsule cover.

[0005] The technical scheme adopted by the utility model is as follows: the utility model provides a kind of full-closed type floating disc PU capsule cover, including capsule cover, the inside of the capsule cover is equipped with keel.

[0006] Further, the capsule cover is made of PU material.

[0007] Further, the keel is made of 304 spring steel wire material.

[0008] The utility model has the beneficial effects as follows by adopting the above structure:

[0009] (1) the capsule cover is made of pu material, PU material itself has excellent wear resistance, so that the capsule cover can resist the loss caused by friction in the use process, prolong the service life, has excellent elasticity and recovery, even after being extruded or stretched by external force, it can also quickly recover to original state, maintain the integrity and function of the capsule cover.

[0010] (2) the capsule cover is made of pu material, PU material can effectively prevent liquid or gas penetration, ensure that the medium in the capsule cover does not leak, meet the high requirement of full-closed type floating disc on sealing, PU material has good resistance to a variety of chemicals, can prevent the capsule cover from being damaged due to contact with corrosive substances.

[0011] (3) The sheath is made of PU material, which is relatively light, facilitating installation and transportation. Meanwhile, the strength of the sheath is sufficient to support the normal operation of the floating disc, ensuring that the floating disc can work stably under various working conditions. The PU material has good resistance to environmental factors such as ultraviolet rays, high temperature and low temperature, enabling the sheath to maintain stable performance in various harsh environments.

[0012] (4) The keel is made of 304 spring steel wire material, which has high strength and toughness, can enhance the supporting force of the sheath, and can quickly restore the original state when the sheath is subjected to external pressure or deformation, thereby ensuring the stability and reliability of the floating disc. The spring has good buffering and damping effect, which can effectively protect the floating disc when it encounters vibration or impact, reducing the damage risk of the sheath and the floating disc.

[0013] (5) The keel is made of 304 spring steel wire material. Since the spring can disperse the pressure borne by the sheath and reduce the burden of the PU material, the service life of the sheath can be prolonged, and the cost of frequent replacement of the sheath can be reduced. The supporting effect of the spring helps to maintain the shape of the sheath, preventing it from deforming due to external force, thereby ensuring that the sealing performance of the sheath is not affected. The elasticity of the spring enables the sheath to better adapt to changes in different working conditions, such as temperature and pressure changes, improving the adaptability of the sheath.
