Abstract
The utility model relates to a single-top and double-pressure sealing device for welding a sluice valve. The device comprises a valve body, wherein a base is arranged at the lower end of the valve body; the base is provided with an overhead beam; the device has the characteristics that a pair of two expansion blocks are distributed above the overhead beam; and the working ends of the two expansion blocks are correspondingly distributed at the two sides of the overhead beam. Therefore, the single-top and double-pressure structure is formed by the base and the two expansion blocks; a sealing surface of a seal pair is formed by a flashboard and the valve body, so as to reduce the abrasion and scratch on the sealing surface of the seal pair formed by the flashboard and the valve body caused by the movement of the flashboard when in sealing; and the service life of the sealing surface of the seal pair is prolonged.
Description
Technical field
The utility model relates to a kind of Dan Dingshuan means of press seals device, relates in particular to a kind of welding gate valve Dan Dingshuan means of press seals device.
Background technique
The welding gate valve be used for coal gas, the air of industries such as iron and steel, metallurgy, coking conveying, block, in use the medium of being carried is regulated, is blocked.
But, mainly be to adopt Single disc that fed sheet of a media is regulated, blocked now, can cause pulling, injuring in various degree to sealing pair during long-time running, easily produce seal failure, can not effectively seal, sealed medium take place leak generation, shorten the working life of gate valve.
The model utility content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of welding gate valve Dan Dingshuan means of press seals device is provided.
For realizing the purpose of this utility model, a kind of welding gate valve Dan Dingshuan means of press seals device, include valve body, described valve body lower end is provided with base, the top is installed on the described base carves, wherein: described top is carved the top and is distributed with the paired piece that rises, and the working end correspondence of two pieces that rise is distributed in the top and carves both sides.
Further, above-mentioned welding gate valve Dan Dingshuan means of press seals device, wherein, described valve interior wall is provided with flashboard, and the piece that rises is connected with flashboard.
Further, above-mentioned welding gate valve Dan Dingshuan means of press seals device, wherein, the described piece that rises is provided with mounting hole, and the piece that rises is connected with the flashboard pin, and pin is arranged in the mounting hole.
Further, above-mentioned welding gate valve wherein, is provided with the top and carves seat with Dan Dingshuan means of press seals device between carve on described base and top.
Again further, above-mentioned welding gate valve Dan Dingshuan means of press seals device, wherein, the described piece working end of rising is provided with lead-in chamfered.
Adopt technical solutions of the utility model; by base and the paired piece formation Dan Dingshuan pressure structure that rises; the sealing pair sealing surface that flashboard and valve body are formed; when sealing, reduce wearing and tearing and the scuffing of the motion of flashboard to flashboard and valve seal secondary sealing area; the protection sealing surface, the working life of prolongation sealing pair sealing surface.
The purpose of this utility model, advantage and characteristics will illustrate by following preferential embodiment's non-limitative illustration and explain that these embodiments only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the organigram of welding gate valve with Dan Dingshuan means of press seals device.
The implication of each reference character is as follows among the figure:
1 piece 2 pins that rise
3 flashboards, 4 valve bodies
5 tops are carved 6 tops and are carved seat
7 bases
Embodiment
As shown in Figure 1, a kind of welding gate valve Dan Dingshuan means of press seals device, include valve body 4, be provided with base 7 in valve body 4 lower ends, the top is installed on this base 7 carves 5, its unusual part is: adopt the top to carve 5 tops and be distributed with the paired piece 1 that rises, and the working end correspondence of two pieces 1 that rise is distributed in the top and carves 5 both sides.
In conjunction with the utility model one preferred implementation, realize effective interlock for the ease of relevant device, valve body 4 inwalls that the utility model adopts are provided with flashboard 3, and the piece 1 that rises is connected with flashboard 3.Like this, in actual moving process, when gate valve blocked, flashboard 3 promoted to drive the piece 1 that rises by valve rod and moves downwards.
Further, for firm connection the between better guarantee to rise piece 1 and the flashboard 3, the piece 1 that rises that the utility model adopts is provided with mounting hole, and the piece 1 that rises is connected with flashboard 3 pins 2, and pin 2 is arranged in the mounting hole.Thus, both can guarantee flashboard 3 and rise being connected between the piece 1, not influence the movement locus of the piece 1 that rises again.
And, consider that the top carves 5 impacts that piece 1 brings that may be subjected to during use rising, between base 7 and top carve 5, be provided with the top and carve seat 6, improve to push up with this and carve working life of 5.Simultaneously, in order to promote the work levels of precision of the piece 1 that rises, on the working end of piece 1 of rising, be provided with lead-in chamfered.
In conjunction with actual using process of the present utility model, when gate valve blocks.Meanwhile, flashboard 3 promote to drive the piece 1 that rises by valve rod and moves downwards.Then, when rise piece 1 and top on the flashboard 3 carve 5 contact after, the conical surface that carve on 5 on the top struts the piece 1 that rises gradually.Subsequently, the 1 pair of flashboard of piece 3 of rising after strutting forms an extruding force, makes the sealing of evenly fitting of the sealing surface of the sealing surface of flashboard 3 and valve body 4.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen; after adopting the utility model; by base and the paired piece formation Dan Dingshuan pressure structure that rises; the sealing pair sealing surface that flashboard and valve body are formed; when sealing, reduce wearing and tearing and the scuffing of the motion of flashboard to flashboard and valve seal secondary sealing area; the protection sealing surface, the working life of prolongation sealing pair sealing surface.
Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
