Abstract

The utility model discloses a gate valve, and belongs to the field of mechanical equipment. The gate valve is communicated with a blanking pipe of an electric furnace, and comprises a gate valve shell, a hydraulic cylinder support, a water cooling tank, a shutter, an aggregate bin, a manual shutter, the blanking pipe of the electric furnace, a water inlet pipe, a water outlet pipe, a dredging pipe, a hydraulic cylinder and a piston rod, wherein the hydraulic cylinder support is connected with the gate valve shell, the aggregate bin is communicated with the gate valve shell, and the manual shutter is arranged on the aggregate bin; the blanking pipe of the electric furnace is communicated with one end of the gate valve shell, the water inlet pipe and the water outlet pipe are communicated with the blanking pipe of the electric furnace, the dredging pipe is communicated with the gate valve shell, the hydraulic cylinder is connected with the hydraulic cylinder support and the piston rod is connected with the hydraulic cylinder. According to the gate valve provided by the utility model, the aggregate bin is arranged, so that the volume of the aggregate bin can be increased, the capacity can be improved, mineral aggregates are free from flow resistance and play a role in communicating with air and reducing vapour; furthermore, the collected mineral aggregates can be taken out by timely opening a warehouse, and the gate valve is unlikely to be blocked.

Description

A kind of push-pull valve
Technical field
The utility model relates to machinery field, particularly a kind of push-pull valve.
Background technique
Push-pull valve is weighlock plate valve, sluice valve or gate etc. also, is installed in the discharge port place or pipeline of vacuum, various powder material hoppers, plays a part to open and turn-off, and also can control by adjusting aperture size the flow of its gas, material.Push-pull valve is the important mechanism on mine thermoelectricity furnace feeding pipe, for controlling turning on and off of feeding pipe, while opening, carries out feed to electric furnace; Turn-off and stop blanking.Its driving mode is that hydraulic control drives.Working principle is, when push-pull valve work, by Driven by Hydraulic Cylinder piston rod, piston rod drives flashboard side-to-side movement, moving direction is vertical with electric furnace feeding pipe, opens blanking and shutoff stops blanking, and the clout on flashboard falls into feed back pipe, flow into electric furnace feeding pipe by feed back pipe, automatically complete collection clout.Because operating ambient temperature is high, need to pass through intake pipe water flowing push-pull valve wall water channel, water flowing water pipe connects water-cooling groove and push-pull valve wall water channel, and water flowing is carried out cooling to push-pull valve, then is flowed out by outlet pipe.
Feed back pipeline
Figure DEST_PATH_IMAGE001
mm is less than normal, has the angle of turning round, the resistance that the dirty existence of mineral aggregate is certain simultaneously; The cooling generation temperature difference of push-pull valve water flowing again, makes water vapour in valve pocket form water droplet inflow feed back pipe, and then the increase of mineral aggregate viscosity, deposits in pipeline crook.Through depositing for a long time, feed back pipe is just filled, and results in blockage, and produces fault.Conventional handling is to knock feed back pipe and open maintenance pipe, clears up; Mineral aggregate bonding, stops up and seriously needs to open the cleaning of valve body entirety.Maintenance ambient temperature is high, dust is large, and while opening maintenance pipe, the toxic gases such as coal gas composition CO, the SO2 in material pipe easily make maintainer poisoning.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides one not allow susceptible to plugging push-pull valve.Described technological scheme is as follows:
The utility model embodiment provides a kind of push-pull valve, described push-pull valve is communicated with electric furnace feeding pipe, described push-pull valve comprises push-pull valve housing, the hydraulic cylinder leg being connected with described push-pull valve housing, be arranged on the water-cooling groove on described push-pull valve housing, be arranged on the flashboard in described push-pull valve housing, the collecting bin being communicated with described push-pull valve housing, be arranged on the manual flashboard on described collecting bin, the electric furnace feeding pipe being communicated with described push-pull valve shell end, the intake pipe and the outlet pipe that are communicated with described electric furnace feeding pipe, the water flowing water pipe being communicated with described push-pull valve housing, the oil hydraulic cylinder being connected with described hydraulic cylinder leg, the piston rod being connected with described oil hydraulic cylinder.
Particularly, described collecting bin dimensional parameters is: heavy caliber 500 × 400mm, small-bore 110 × 110mm, high 750mm.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
By collecting bin is set, collecting bin volume increases, and charging capacity increases, and mineral aggregate, without flow resistance, plays and air communication simultaneously, reduces the effect of water vapour; Timing opens a position and takes out the mineral aggregate of collecting, and push-pull valve is not easy to stop up.
Brief description of the drawings
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model mode of execution is described in further detail.
Embodiment
The utility model embodiment provides a kind of push-pull valve, referring to Fig. 3, Fig. 4, described push-pull valve is communicated with electric furnace feeding pipe 7, described push-pull valve comprises push-pull valve housing 1, the hydraulic cylinder leg 2 being connected with push-pull valve housing 1, be arranged on the water-cooling groove 3 on push-pull valve housing 1, be arranged on the flashboard 4 in push-pull valve housing 1, the collecting bin 5 being communicated with push-pull valve housing 1, be arranged on the manual flashboard 6 on collecting bin 5, the electric furnace feeding pipe 7 being communicated with push-pull valve housing 1 end, the intake pipe 8 being communicated with electric furnace feeding pipe 7 and outlet pipe 9, the water flowing water pipe 10 being communicated with push-pull valve housing 1, the oil hydraulic cylinder 11 being connected with hydraulic cylinder leg 2, the piston rod 12 being connected with oil hydraulic cylinder 11.
Preferably, collecting bin 5 dimensional parameters are, heavy caliber 500 × 400mm, small-bore 110 × 110mm, high 750mm.
The beneficial effect that the technological scheme that the utility model embodiment provides is brought is:
