Background technology
The down-hole paste body filling equipment of prior art, many straight tubes of its filling pipe route are formed by connecting through pipe clamp, establish a threeway at a distance from a segment distance, and threeway is blocked through bolt with sealing plate when normal filling.When the plugging accident takes place, often adopt manual blowing mode, manually in the blowing process, need the 3rd mouth of pipe of interface threeway on the filling pipeline be disassembled with spanner, reach the purpose of blowing.Though this kind blowing discharge way is feasible technically, safety is not high, and adopts manual blowing, wastes time and energy.The pressure of existing in addition filling pipeline in can't signal piping can not detect the pressure of whole pipeline, causes production accident easily.
Summary of the invention
The present invention is directed to defective of the prior art, a kind of paste body filling plugging discharge gate that has the pressure detecting function be provided, this gate can not only be when plugging quickly discharging material automatically, but also can detect the pressure in the filling pipeline.
Its technical solution is: a kind of paste body filling plugging discharge gate that has the pressure detecting function, comprise the trunk line that is connected on the filling pipeline, and the tube wall of trunk line is provided with the discharge pipe that is connected with trunk line; Offer discharge port on the tube wall of discharge pipe; The end of discharge pipe is connected with hydraulic cylinder, and the piston rod of hydraulic cylinder is towards discharge pipe, and the end of piston rod is provided with circular baffle plate; The outer wall of baffle plate contacts with the inner wall sealing of discharge pipe; When piston rod stretches out, in the discharge pipe of baffle plate between trunk line and discharge port, trunk line is sealed; When piston rod is withdrawn, in the discharge pipe of baffle plate between the end of discharge port and discharge pipe; Above-mentioned hydraulic cylinder is furnished with the hydraulic system of control piston motion.
Above-mentioned hydraulic system comprises fuel tank; Fuel tank is connected with oil pump through pipeline; Oil pump is connected with first interface of three position four-way electromagnetic valve through pipeline, and second interface of three position four-way electromagnetic valve is connected with the loculus of hydraulic cylinder through pipeline, and the 3rd interface of three position four-way electromagnetic valve is communicated with the big chamber of hydraulic cylinder through pipeline; Pipeline between the 3rd interface and the big chamber is provided with pressure sensor, and the 4th interface of three position four-way electromagnetic valve is connected with fuel tank through pipeline.
Above-mentioned pressure sensor is electrically connected with single-chip microcomputer, and single-chip microcomputer is electrically connected with three position four-way electromagnetic valve.
The invention has the beneficial effects as follows: when normal filling, in the discharge pipe of circular baffle plate between trunk line and discharge port, the lotion slip flows to the filling operation position through trunk line; When the plugging accident takes place when, the increased pressure in the trunk line, compressing baffle plate, pressure sensor detect in the big chamber of hydraulic cylinder pressure and with pressure signal transmission to single-chip microcomputer; Single-chip microcomputer according to pressure signal with preestablish numerical value and compare, judge whether to take place the plugging accident, if the plugging accident takes place, single-chip microcomputer is given the three position four-way electromagnetic valve signal of telecommunication; Make the three position four-way electromagnetic valve switching-over, make the oil return of big chamber, the loculus oil-feed; Baffle plate moves in the discharge pipe between discharge port and the discharge pipe end, opens discharge port and accomplishes the discharging blowing, accomplishes the function of plugging discharging automatically; When single-chip microcomputer is confirmed the detected pressure signal of pressure sensor less than preset value, can think that discharging is accomplished and the transmission signal is given three position four-way electromagnetic valve, make the three position four-way electromagnetic valve switching-over; Big chamber oil-feed, the loculus oil return makes baffle plate that discharge port is sealed; Proceed filling operation, realized unmanned management, improved security performance.
