Description
Technical field
The utility model relates to high pressure cock valve accessory technical field, specially a kind of novel high-pressure plug valve sealing valve
Seat.
Background technique
Currently, high pressure cock valve is all made of curved surface sealing, by sealing arcs sealing ring and valve body curved face contact, curved surface is close
For envelope because the characteristic of contact form causes the sealing effect under high pressure operating condition bad, sealing arcs answer self-strength not high in high compression ring
Easily-deformable service life is shorter under border, and difficulty of processing is big, so that manufacturing cost is greatly increased, due to sealing in assembling process
Arcs require height using positioning finger setting and cooperation, lead to assembly difficulty, time-consuming and laborious, for this purpose, the utility model provides one
Kind novel high-pressure plug valve seal valve seat.
Utility model content
In view of the deficienciess of the prior art, the utility model aim is to provide a kind of novel high-pressure plug valve sealing valve
Seat, to solve the problems mentioned in the above background technology, the utility model is designed reasonably, the service life is longer, and sealing effect is more
It is good.
To achieve the goals above, the utility model is achieved through the following technical solutions: a kind of novel high-pressure revolves
Plug valve seal valve seat, including seal valve seat main body, the quantity of the seal valve seat main body are 2, in the seal valve seat main body
Radial seal groove and plane seal groove are offered, radial direction seal ring, the flat seal slot are inlaid in the radial seal groove
It is inside inlaid with planar seal ring, body cavity is offered in valve body, two seal valve seat main bodys are installed in body cavity
It is interior, cock is installed between two seal valve seat main bodys.
As a kind of preferred embodiment of the utility model, the position of two seal valve seat main bodys is corresponding.
As a kind of preferred embodiment of the utility model, the quantity of the flat seal slot and planar seal ring is 2.
The utility model has the beneficial effects that a kind of novel high-pressure plug valve seal valve seat of the utility model, including valve body,
Planar seal ring, seal valve seat main body, cock, radial direction seal ring, radial seal groove and plane seal groove.
1. this novel high-pressure plug valve seal valve seat is set by way of improving seal form and transformation sealing structure
Meter, seal valve seat body design are cylindrical structure, are changed to flat seal by curved surface sealing with valve body, sealing effect is more preferably, close
It seals valve seat body section sealing ring and uses double layer planar sealing ring, Xiang Xuansai thrust is bigger, and the service life is longer, and sealing effect is more
Good, seal valve seat main body adds radial direction seal ring again in addition to flat seal, forms sealing dual fail-safe, and seal valve seat body design is
Certain taper is easily installed and dismantles.
2. novel high-pressure plug valve seal valve seat is structurally reasonable, intensity is high, machining accuracy is high, precision size for this, and is not easy
Deformation, the service life is longer, is more suitable for high pressure, huge discharge occasion, seal valve seat main body and cock contact jaw are cambered surface, with cock
It fits closely, there is good locating effect, both limited the dynamic and axial movement of the radial-play of seal valve seat main body, there are also protect
Protect the effect of seal valve seat main body.
3. the seal valve seat main body of this novel high-pressure plug valve seal valve seat uses stainless steel making, it can be avoided to get rusty and lead
Cause seal failure.
Detailed description of the invention
Fig. 1 is a kind of scheme of installation of novel high-pressure plug valve seal valve seat of the utility model；
Fig. 2 is a kind of seal valve seat agent structure schematic diagram of novel high-pressure plug valve seal valve seat of the utility model；
In figure: 1- valve body, 2- planar seal ring, 3- seal valve seat main body, 4- cock, 5- radial direction seal ring, 6- are radially close
Sealing groove, 7- flat seal slot.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Fig. 1 to Fig. 2 is please referred to, the utility model provides a kind of a kind of novel high-pressure plug valve seal valve seat of technical solution,
Including seal valve seat main body 3, the quantity of the seal valve seat main body 3 is 2, offers radial direction in the seal valve seat main body 3
Seal groove 6 and plane seal groove 7 are inlaid with radial direction seal ring 5 in the radial seal groove 6, inlay in the flat seal slot 7
There is planar seal ring 2, body cavity is offered in valve body 1, two seal valve seat main bodys 3 are installed in body cavity,
Cock 4 is installed between two seal valve seat main bodys 3.
As a kind of preferred embodiment of the utility model, the position of two seal valve seat main bodys 3 is corresponding.
As a kind of preferred embodiment of the utility model, the quantity of the flat seal slot 7 and planar seal ring 2 is 2
It is a.
Working principle: seal valve seat main body 3 is designed as cylindrical structure, using stainless steel making, avoid get rusty cause it is close
Envelope failure is changed to flat seal by curved surface sealing with valve body 1, and the flat seal of seal valve seat main body 3 is close using double layer planar
Seal 2 forms double-layer seal, and 4 thrust of Xiang Xuansai is bigger, and when work, what the oriented cock 4 always of seal valve seat main body 3 moved becomes
Gesture guarantees sealing performance, sealing effect is more preferable, and service life is more so that seal valve seat main body 3 be enable to combine closely with cock 4
Long, seal valve seat main body 3 adds radial direction seal ring 5 again except planar seal ring 2 in addition to, forms sealing dual fail-safe, body cavity edge into
