Description
Technical Field
The utility model relates to a blind plate valve field, more specifically the utility model relates to a high temperature blind plate valve that says so.
Background
The blind plate valve switches between the blind hole plate and the through hole plate and seals the valve seat and the blind hole plate or the through hole plate by adjusting the gap between the valve seat and the valve plate, can realize the cutting of a pipeline and the isolation of related equipment, and has the advantages of single-person operation, no need of special tools, low labor intensity of workers and short switching time.
The existing blind plate valve has defects, both the blind plate valve and the through plate valve comprise a valve ring and two sealing rings which are respectively positioned on two end faces of the valve ring, and in a high-temperature environment, the sealing rings are easily heated and have elastic failure, so that the sealing rings are broken under the pushing of a high-pressure medium to cause leakage.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a blind plate valve suitable for high temperature environment and leakproofness are stable.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a high temperature blind plate valve, includes the valve body, with valve plate, two valve rings of valve body swivelling joint on the valve plate and the blind plate of being located one of them valve ring, two all be provided with first sealing washer on two terminal surfaces of valve ring, two all be provided with on two terminal surfaces of valve ring with the coaxial setting of first sealing washer and the second sealing washer that hinders heat, two the maximum diameter of second sealing washer all is less than the minimum diameter of first sealing washer.
As a further improvement of the utility model, two the first sealing ring is made of fluororubber material.
As a further improvement of the utility model, two the second sealing washer all adopts ceramic fiber material to make.
As a further improvement, two still be provided with the third sealing washer the same with first sealing washer material and the fourth sealing washer the same with the second sealing washer material, two on two terminal surfaces of valve collar the internal diameter of fourth sealing washer all is greater than the external diameter of first sealing washer, two the internal diameter of third sealing washer all is greater than the external diameter of fourth sealing washer.
The utility model has the advantages that: all be provided with on two terminal surfaces of two valve rings with first sealing washer coaxial setting and hinder hot second sealing washer, the maximum diameter of two second sealing washers all is less than the minimum diameter of first sealing washer, first sealing washer and second sealing washer all form sealedly with the valve body, so the design is compared the design that prior art only adopted a sealing washer and can be formed soft or hard double seal, the second sealing washer that adopts to hinder hot material to make simultaneously has good heat-proof quality, effectively avoid heat conduction to go up first sealing washer, thereby the life of first sealing washer has been improved indirectly, the sealing stability of first sealing washer has been ensured.
Drawings
Fig. 1 is a front view of the present invention;
FIG. 2 is a right sectional view of the present invention;
fig. 3 is an enlarged view of a portion a in fig. 2.
Reference numerals are as follows: 1. a valve body; 2. a valve plate; 3. a valve ring; 4. a blind plate; 5. a first seal ring; 6. a second seal ring; 7. a third seal ring; 8. and a fourth seal ring.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. In which like parts are designated by like reference numerals.
Referring to fig. 1 to 3, the high-temperature blind plate valve of the present embodiment includes a valve body 1, a valve plate 2 rotatably connected to the valve body 1, two valve rings 3 positioned on the valve plate 2, and a blind plate 4 positioned in one of the valve rings 3, wherein two end surfaces of the two valve rings 3 are both provided with a first sealing ring 5;
based on the prior art, two end faces of the two valve rings 3 are respectively provided with a second sealing ring 6 which is coaxial with the first sealing ring 5 and is heat-resistant, the maximum diameter of the two second sealing rings 6 is smaller than the minimum diameter of the first sealing ring 5, the two first sealing rings 5 are both made of fluororubber materials, the two second sealing rings 6 are both made of ceramic fiber materials, in the using process, the two first sealing rings 5 are both attached to the end faces of the valve body to form soft sealing, the two second sealing rings 6 are both attached to the end faces of the valve body to form hard sealing, and the first sealing rings 5 and the second sealing rings 6 have a gap;
compared with the prior art, the design of only adopting a sealing ring can form soft and hard dual seal, and the second sealing ring 6 made of ceramic fiber material has good pressure resistance and heat insulation performance, thereby effectively avoiding heat conduction to the first sealing ring 5, indirectly prolonging the service life of the first sealing ring 5 and ensuring the sealing stability of the first sealing ring 5.
As an improved specific embodiment, referring to fig. 3, two end faces of the two valve rings 3 are further provided with a third seal ring 7 made of the same material as the first seal ring 5 and a fourth seal ring 8 made of the same material as the second seal ring 6, inner diameters of the two fourth seal rings 8 are both greater than an outer diameter of the first seal ring 5, and inner diameters of the two third seal rings 7 are both greater than an outer diameter of the fourth seal ring 8, so that the two seal rings made of the two materials can be alternately arranged, after the first seal ring 5 and the second seal ring 6 are damaged, effective soft and hard double sealing is formed by the third seal ring 7 and the fourth seal ring 8, sealing stability is further ensured, and the maintenance period of the valve plate 2 is prolonged.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
