Abstract
The invention provides a flange connection sealing device, which comprises a flange seat and a flange cover, and is characterized in that a passage is arranged on the inner wall of the flange seat, the upper end of the passage is communicated with a liquid suction pipe, and the lower end of the passage is communicated with a tank body. The passage is formed on the inner wall of the flange seat of the flange connection sealing device, the lower part of the passage is communicated with a gas phase space of the tank body, and the upper part of the passage is communicated with the gas phase space of the liquid suction pipe, so the pressure of the gas phase space in the tank body can always keep a balanced state with the pressure of the gas phase space of the liquid suction pipe in the work process, media cannot be pressed out of a liquid suction device by the internal pressure of the tank body, a sealing pad is fixed in a groove of the flange cover through a press cover, a T-shaped groove is arranged on the flange cover, the press cover is tightly pasted with the flange cover though a fastener, and the sealing pad can be effectively prevented from dropping.
Description
Technical field
The present invention relates to a kind of joint seal of flanges device, relate in particular to a kind of flange connecting apparatus.
Background technique
The following several modes of existing joint seal of flanges:
1, at the pumping pipe top a pair of convex surface or male and female flange are set, realize sealing with bolton.
2, on pumping pipe top blind flange, flange seat are set, flange seat upper edge Flange Plane substantially horizontal is provided with lug, realize sealing by bolt flange lid and flange seat, an end of blind flange cooperates with the flange seat bearing pin, and blind flange is to be that running shaft rotarily opens by this bearing pin.
More than two kinds of joint seal of flanges devices all have following shortcoming:
1, flange is fastening by the bolt manual operation, has the poorly sealed hidden danger that may cause leakage.Flow container in use owing to reasons such as temperature rising media expansion, causes the tank body internal pressure to be higher than barometric pressure, and pressure causes medium liquid level rising in the pumping pipe, and pumping device is poorly sealed may to cause dielectric leakage.
2, sealing gasket might come off or lose.
In addition, also having a kind of sealing means that connects is on the basis of above-mentioned first kind or the second way, at pumping device top flange lid flexible pipe is set, and the other end of flexible pipe communicates with the liquid pipe, is used for the pressure of equilibrium liquid tank body gas-phase space and pumping pipe gas-phase space.Though this mode makes moderate progress to eliminating leakage hidden danger, and is limited to Korrosionsmedium such as concentrated sulphuric scid role, and flexible pipe working life and very short.
Summary of the invention
In order to solve existing technical problem in the background technique, the present invention proposes a kind of joint seal of flanges device, solved the technical problem of the poorly sealed possibility of flange connecting apparatus leakage in the background technique.
Technical solution of the present invention is: the joint seal of flanges device, comprise flange seat and blind flange, it is characterized in that: described joint seal of flanges device, the flange seat inwall is provided with passage, the upper end of described passage is communicated with pumping pipe, and the lower end of described passage is communicated with tank body.
Above-mentioned passage is two, and symmetry is along the inwall setting of flange seat respectively.
Be provided with gland in the above-mentioned groove, leave between described gland and the passage and make the breach that gas communicates in passage and the flange seat.
Be provided with sealing gasket between above-mentioned gland and the blind flange groove, described gland closely is connected with sealing gasket by fastening piece.
Above-mentioned flange seat radially is vertically installed with lug, and described blind flange is provided with pin-and-hole, and described lug is connected with pin-and-hole.
Groove on the above-mentioned blind flange is a T-slot.
Advantage of the present invention is:
1) forms a passage at the flange seat inwall, the passage bottom communicates with the tank body gas-phase space, passage top communicates with the pumping pipe gas-phase space, gas-phase space pressure and pumping pipe gas-phase space pressure total energy keeps balance in the tank body so in the course of the work, and medium is unlikely to be extruded outside the pumping device by tank interior pressure.
2) sealing gasket is fixed in the blind flange groove by gland, and a T-slot is arranged on the blind flange, and gland is close to blind flange by fastening piece, can effectively avoid sealing gasket to come off.

Embodiment
Referring to Fig. 1, Fig. 2, the joint seal of flanges device that the present invention proposes, comprise flange seat 1, blind flange 2, be provided with passage 14 at flange seat 1 inwall, passage 14 is two, respectively along the interior edge of flange seat 1, one end of passage 14 communicates with the tank body gas-phase space, the other end of passage 14 communicates with the pumping pipe gas-phase space, so in the course of the work, gas in the tank body flows to the pumping pipe gas-phase space by passage 14, and gas-phase space pressure and pumping pipe gas-phase space pressure total energy keeps balance in the tank body, and medium is unlikely to be extruded outside the pumping device by tank interior pressure.
The setting of in the present invention flange seat 1 internal channel adapts, sealing configuration between flange seat 1 and blind flange 2 has also been done corresponding adjustment, one side of flange seat 1 is provided with pivot hole, one end of blind flange 2 is connected with flange seat 1 by pivot hole, radially be vertically installed with lug 13 along flange seat 1, lug 13 is positioned at the outer of flange seat 1; T-slot 27 is set on the blind flange 2, fastening piece 5 is housed in the T-slot 27, gland 4 is close on the blind flange 2 by fastening piece 5, and sealing gasket 3 is fixed in the groove 28 of blind flange 2 by gland 4.The joint of pivot hole is " L " shape, is symmetrical arranged 4 pairs of lugs.Blind flange 2 is provided with handle 26, and handle 26 is an integral piece with blind flange 2.
In envelope during blind flange, the pin-and-hole 25 of blind flange 2 upper sheds with along the radially vertically disposed protruding 13 ears coupling of flange seat 1, fixing with clamping bolt 6; When opening the joint seal of flanges lid, unclamp clamping bolt 6, and open clamping bolt 6 along the opening of pin-and-hole 25, pulling handle 26, handle 26 and blind flange 2 around pivot hole along flange seat 1 radially Vertical direction rotate.
