Detailed Description
The present invention will be described below based on examples, but it should be noted that the present invention is not limited to these examples. In the following detailed description of the present invention, certain specific details are set forth in detail. However, for parts not described in detail, those skilled in the art can fully understand the present invention.
Furthermore, those skilled in the art will appreciate that the drawings are provided for purposes of illustrating the objects, features, and advantages of the invention and are not necessarily drawn to scale.
Also, unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, the meaning of "includes but is not limited to".
FIG. 1 is a schematic structural diagram of a gate of a metering room according to an embodiment of the present invention; fig. 2 is a schematic perspective view of a gate of the metering room according to the embodiment of the present invention; in fig. 1 and 2, a gate between metering chambers includes a fixed valve seat and an opening and closing member, the fixed valve seat is detachably connected with a movable valve seat 4, and the movable valve seat 4 is used for cooperating with the opening and closing member to complete the opening or closing of the gate.
In order to ensure the tightness of the gate, the contact surfaces of the movable valve seat 4 and the fixed valve seat are sealing surfaces, and the contact surfaces of the movable valve seat 4 and the opening and closing member are also sealing surfaces.
The gate between measurement of this embodiment, the movable valve seat has been connected in the higher authority of fixed disk seat can be dismantled, and the opening and closing piece of gate directly constitutes sealed vice with the movable valve seat, when the opening and closing piece is sat and is sealed on the movable valve seat, closes the circulation passageway of gate, when the opening and closing piece leaves the movable valve seat, opens the circulation passageway of gate, satisfies the normal operating requirement of gate.
The gate between measurement of this embodiment, in the use, because of can dismantle above the solid fixed valve seat and connect movable valve seat, opening or closing of gate is accomplished through the cooperation of opening and close piece and movable valve seat, so do not carry the medium to pass through between the sealed face of solid fixed valve seat and movable valve seat, also be the state of keeping sealed between the two always, carry the medium and can not corrode solid fixed valve seat's sealed face, the wearing and tearing of solid fixed base in the gate use have been avoided, therefore solid fixed valve seat's sealed face can not damaged usually.
When the gate of the embodiment is used for a period of time, if the gate is not tightly sealed, the sealing assembly connected with the valve body is disassembled, the opening and closing piece and the lead screw are taken out of the valve body, and the sealing surface of the opening and closing piece is corroded and damaged or the sealing surface of the movable valve seat is corroded and damaged or the sealing surfaces of the opening and closing piece and the movable valve seat are corroded and damaged, so that only the opening and closing piece or the movable valve seat which is corroded and damaged in the same type is needed to be replaced, the valve body with the fixed valve seat and higher volume and processing cost is not needed to be replaced, and the maintenance cost is saved.
In fig. 1 and 2, the side wall of the movable valve seat 4 is provided with a window for communicating with the flow passage of the shutter.
The movable valve seat 4 is arranged on the fixed valve seat, the height of the original fixed valve seat is increased, the cross-sectional area of a gate flow passage is inevitably reduced, and in order to reduce the influence of the height of the movable valve seat 4 as much as possible, a plurality of windows are arranged on the side wall of the movable valve seat 4, so that the flowing medium flowing through the gate flow passage can smoothly pass through the windows.
In fig. 1, the shutter is connected to a threaded spindle 1, by means of which spindle 1 the shutter is controlled to set or unseat from a movable valve seat 4 to complete the opening or closing of the gate.
The top end of the screw rod is preferably connected with a driving piece, the screw rod 1 is driven to rotate by the driving piece, and the screw rod 1 rotates to drive the opening and closing piece to be set or separated from the movable valve seat 4 so as to complete the opening or closing of the gate.
The driving member may be a hand wheel which is generally used.
As with the conventional metering chamber gate, the fixed valve seat is disposed within the valve body, i.e., the fixed valve seat is disposed on the flow passage of the valve body, and the fixed valve seat may be integrally formed with the valve body.
Because the lead screw 1 plays a role in controlling the opening and closing piece to sit or leave the movable valve seat 4 to complete the opening or closing of the gate, the opening and closing piece and the movable valve seat also need to be in the valve body 1, and meanwhile, the valve body also needs to be sealed, so a sealing structure needs to be arranged in a gap between the lead screw 1 and the valve body, therefore, the sealing assembly 2 is connected outside the lead screw 1, the gap between the sealed lead screw 1 and the valve body is sealed through the sealing assembly 2, and the sealing requirement inside the valve body is ensured.
Corresponding seal assembly 2's selection, this application embodiment compares the lead screw sealing mode of gate between current measurement and does not improve, specifically, this seal assembly 2 includes packing box and packing gland, and the packing box is used for built-in sealed packing, and sealed packing is used for the clearance of sealed lead screw 1 and valve body, and packing gland is used for fixing the packing box on the valve body.
In fig. 1 and 3, a shutter 3 is used as the shutter.
The shutter 3 is detachably connected to the shutter, for example, by screwing. When guaranteeing that the gate is sealed not tight, if it is tight because the flashboard 3 is corroded and damages the sealed that leads to, can change flashboard 3, only need during the change with flashboard 3 follow lead screw 1 dismantle to it can to change the flashboard 3 of the same specification.
Of course, if the lead screw 1 is damaged due to corrosion, the lead screw 1 is not flexible to rotate, and the opening or closing speed of the gate is affected, the lead screw 1 can be replaced, because the lead screw 1 and the gate plate 3 are detachably connected.
Meanwhile, the lead screw 1 and a driving part at the upper end, such as a hand wheel, also adopt a detachable connection mode so as to replace the lead screw 1.
The above-mentioned embodiments are merely embodiments for expressing the invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, substitutions, modifications, etc. can be made without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
