Abstract

The utility model relates to a blind plate, including the blind plate body, blind plate body center is equipped with central slotted hole, is equipped with the seal positioning ring groove on the blind plate body, and the seal positioning ring inslot is equipped with seal ring, and central slotted hole position is equipped with the tight passageway of locating clip to blind plate body outward flange on the blind plate body. Compared with the prior art, the utility model has following advantage: overall structure is simple, and the manufacture craft is simple and convenient, has reduced the limitation of connecting, has prolonged life, has also practiced thrift the cost, connects reliably, has increased blind plate's fastness, leakproofness and compressive capacity.

Description

A kind of blind plate

Technical field

This utility model relates to a kind of blind plate.

Background technology

The canonical name of blind plate is blind flange, also referred to as blind flange or the pipe plug having.It is middle flange the most with holes, For blocking pipe mouth.The function played is the same with end socket and pipe cap, and only blind plate sealing is a kind of dismountable Sealing device, and the sealing of end socket does not prepare to open again.The form kind of sealing surface is more, has plane, convex surface, concavo-convex Face, tongue and groove and ring joint face.Material has carbon steel, rustless steel, steel alloy, copper, aluminum, PVC and PPR etc..

Blind plate is a kind of part for blocking pipe mouth.At present, all use in the pipeline of industry-by-industry every field Arrive blind plate.In chemical industry, often touching some has pollution to environment, the liquid being hazardous to the human body, these liquid Body conveying is the most careful.In the prior art, blind plate is only connected with pipeline by bolt, although the simplest in operation and dismounting Single, but when the pressure of the liquid of conveying is excessive, it is easy to blind plate is caused huge impact so that these have dirt to environment Dye, the liquid being hazardous to the human body can flow out pipeline, and environment and the mankind will be caused imponderable injury by this.Therefore, blind plate Fastness and sealing very important.

Therefore, it should provide a kind of new technical scheme to solve the problems referred to above.

Summary of the invention

This utility model provides a kind of blind plate.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is:

A kind of blind plate, including blind plate body, blind plate body central is provided with center slotted eye, and blind plate body is provided with sealing location Ring recess, is provided with seal washer in sealing location ring recess, and on blind plate body, central channel hole site is provided with to this outer rim of blind plate and determines Position clamping channel.

The relevant content of technique scheme is explained as follows:

In technique scheme, it is circular for sealing location ring recess, seals location ring recess and arranges with center slotted eye concentric circular.

Further technical scheme, location clamping channel communicates between the ring recess of location with sealing.

Preferably, location clamping channel is angularly arranged along center slotted eye.

Owing to technique scheme is used, this utility model compared with prior art has the advantage that

Overall structure is simple, and processing technology is easy, reduces the limitation of connection, extends service life, also saves Cost, connects reliable, adds the fastness of blind plate, sealing and anti-pressure ability.

Accompanying drawing explanation

Accompanying drawing 1 is this utility model schematic diagram.

In the figures above: 1, blind plate body；2, center slotted eye；3, location ring recess is sealed；4, seal washer；5, location clamping Passage.

Detailed description of the invention

Below in conjunction with the accompanying drawings and this utility model is further described by embodiment:

Embodiment one:

As it is shown in figure 1, a kind of blind plate of the present utility model, including blind plate body 1, blind plate body 1 center is provided with central channel Hole 2, blind plate body 1 is provided with sealing location ring recess 3, and it is circular for sealing location ring recess 3, seals location ring recess 3 and center slotted eye 2 Concentric circular is arranged, and is provided with seal washer 4 in sealing location ring recess 3, and on blind plate body 1, center slotted eye 2 position is outside blind plate body 1 Edge is provided with location clamping channel 5, quickly positions, and location clamping channel 5 communicates between the ring recess 3 of location with sealing, location clamping Passage 5 angularly arranges (for the 120 ° of settings in interval in Fig. 1) along center slotted eye 2, and overall structure is simple, and processing technology is easy, fall The low limitation connected, extends service life, also saves cost, connects reliable, adds the fastness of blind plate, sealing Property and anti-pressure ability.Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with this The personage of item technology will appreciate that content of the present utility model and implements according to this, can not limit protection of the present utility model with this Scope.All equivalence changes made according to this utility model spirit or modification, all should contain in protection of the present utility model Within the scope of.
