Abstract
The utility model relates to an indicating brake-valve with contact opened when electrified, comprising a valve body, a sealing ring, a valve gate board, a valve rod, a valve cover, an oil immersed hemp packing root, a padding gland, a dustproof cover, an opening indicating plate, a travel switch assembly, a switch supporting plate, a hand wheel, etc. The indicating plate of the utility model is arranged at the upper end part of the valve rod via screw threads, the switch supporting plate is fixedly connected with the valve cover, and the travel switch assembly is arranged on the switch supporting plate and sealed by the dustproof cover. The utility model can monitor the opening state and the closing state of the brake-valve according to whether a red light and a green light in a control room is turned on or not. The indicating brake-valve with contact opened when electrified having simple structure, reliable motion and low cost is especially suitable for a fire control system.
Description
The utility model relates to a kind of gate valve, and particularly a kind of live contact is opened the indication gate valve.
Original gate valve is in the state of opening or closing, and does not know in the control room; Also have some gate valves that indication mechanism has been installed in the control room, but its complex structure is heavy, so can not get applying.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of opening or closing of gate valve that can show in the control room is provided, and simple and reasonable, lower-cost live contact is opened the indication gate valve.
The purpose of this utility model can reach by following measure: the utility model comprises valve body, seal ring, valve flashboard, valve rod, valve gap, oil immersion fiber crops packing, Gland, position limit switch assembly, handwheel, it is characterized in that: also have dust-proof cover, aperture indicator board, switch support plate, the aperture indicator board is loaded on the upper end portion of valve rod by screw thread, switch support plate and valve gap are affixed, the position limit switch assembly is loaded on the switch support plate, and covers by dust-proof cover.
The purpose of this utility model can also reach by following measure: the trundle in the position limit switch assembly can be oppressed in the right side of aperture indicator board, and spring one end in the position limit switch assembly links to each other with support arm, and the other end links to each other with the switch support plate.
Fig. 1 is structure of the present utility model (an analysing and observe) schematic representation.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, the utility model is made up of valve body 1, seal ring 2, valve flashboard 3, valve rod 4, valve gap 5, oil immersion fiber crops packing 6, Gland 7, dust-proof cover 8, aperture indicator board 9, position limit switch assembly 10, switch support plate 11, handwheel 12 etc.Position limit switch assembly 10 comprises trundle 13, support arm 14, spring 15, contact 16 etc.; Also have red light 17, green light 18, power supply in addition, be loaded in the control room.
It is 1 millimeter left hand thread that pitch is arranged in valve rod 4 upper end portions, and it is the aperture indicator board 9 of 1 millimeter levogyrate inner thread that pitch is installed on the bar, and valve flashboard 3 and valve rod 4 are to be that 4 millimeters left-handed trapezoidal thread meshes with pitch.By handwheel 12 rotation valve rods 4, valve flashboard 3 moves upward 4 millimeters, and aperture indicator board 9 moves up 1 millimeter.Position limit switch assembly 10 is loaded on the neck of gate valve, is positioned at below the handwheel 12, relies on three button-headed screws of switch support plate 11 usefulness firmly to be connected with valve gap 5.Dust-proof cover 8 is placed on the position limit switch assembly 10.
When valve flashboard 3 whole passes were dead, current were cut off, and at this moment aperture indicator board 9 is in the lowest positions (see figure 1) on valve rod 4.On the trundle 13 of its aperture indicator board 9 right-hand members compressing in position limit switch, and force spring 15 to elongate, support arm 14 clockwise rotates, the contact 16 on the right is in conjunction with (left side disconnections), red light circuit the connection at this moment and green light circuitry cuts is reflected in the control room, red light is bright, and green light goes out.
When rotating handwheel 12, valve flashboard 3 raises up, and current are logical.When valve flashboard 3 increases by more than 50, aperture indicator board 9 also promotes over half, at this moment the plate ramp partly contacts with trundle 13, support arm 14 inhour under the effect of spring force is rotated, and drive contact point arm, the green light circuit is connected, and the red light circuit cuts off, and knows just that in the control room gate valve opens.
The utility model has following advantage compared to existing technology:
1, knows namely that according to being loaded on light on and off red in the control room, green light gate valve is in the state of opening or closing, supervise easy to use.
2, simple and reasonable, reliable in action, cost is lower, is specially adapted in the fire-fighting system.
Claims (2)
1, a kind of live contact is opened the indication gate valve, comprise valve body 1, seal ring 2, valve flashboard 3, valve rod 4, valve gap 5, oil immersion fiber crops packing 6, Gland 7, position limit switch assembly 10, handwheel 12, it is characterized in that: also have dust-proof cover 8, aperture indicator board 9, switch support plate 11, aperture indicator board 9 is loaded on the upper end portion of valve rod 4 by screw thread, switch support plate 11 is affixed with valve gap 5, position limit switch assembly 10 is loaded on the switch support plate 11, and covers by dust-proof cover 8.
2, gate valve according to claim 1 is characterized in that: the trundle 13 in the position limit switch assembly 10 can be oppressed in the right side of aperture indicator board 9, and spring 15 1 ends in the position limit switch assembly 10 link to each other with support arm 14, and the other end links to each other with switch support plate 11.
