The invention relates to a loop ligature device capable of continuously launching negative pressure to suck a haemorrhoid. The loop ligature device comprises a loop ligature device shell, a fixing tube, a pushing tube, a launching trigger and a gas inlet valve trigger. A cylinder is arranged in a handle of the loop ligature device shell, and a cylinder body of the cylinder and the loop ligature device shell are fixed. The bottom of a piston is connected with the gas inlet valve trigger through a movable pulling rod. A gas inlet one-way valve and a gas outlet one-way valve are arranged at the gas outlet of the cylinder. The gas inlet one-way valve is communicated with the fixing tube through a pipeline. A deflation valve is arranged on the pipeline between the gas inlet one-way valve and the fixing tube. A fixing threaded rod is arranged on the head of the fixing tube, a pushing threaded rod is arranged on the head of the pushing tube, a plurality of sliding grooves are evenly formed in the fixing threaded rod, and the pushing threaded rod is embedded into the sliding grooves of the fixing threaded rod. By means of the loop ligature device, continuous rubber gasket launching loop ligature can be achieved, pressure of the loop ligature device for adsorbing the haemorrhoid can be observed, and pains or discomfort of patients can be avoided.

The invention belongs to the technical field of device throwing and launching, and particularly relates to a launching device. According to the technical scheme, a pneumatic type launching device is characterized by comprising a launching cylinder (9), a relief valve installed in a cylinder body of the launching cylinder (9), an electromagnetic valve (1) and an air inlet nozzle (2), wherein the electromagnetic valve (1) and the air inlet nozzle (2) are installed on an end cover of the launching cylinder (9). According to the pneumatic type launching device, a high-pressure air source is communicated with an inner cavity of the relief valve to enable the inner cavity of the relief valve to form a high-pressure air cavity, the electromagnetic valve (1) is instantly opened through impulse voltage, a valve element of the relief valve is opened under the action of air pressure, pressure air in the high-pressure air cavity of the relief valve is relieved instantly in the launching cylinder (9), and the purpose of launching is realized. When the launching is completed, the valve element of the relief valve automatically returns to an original launching state rapidly, and continuous launching can be achieved by controlling the impulse voltage of the electromagnetic valve.

The invention discloses an automatic air gun for measuring oil well liquid level. The automatic air gun for measuring oil well liquid level comprises a pilot deflation electromagnetic valve, a valve cover, a valve body, a main valve combination arranged in the valve body, an adjusting spring, an inflation / deflation electromagnetic valve and a wellhead connector, wherein one side of the valve bodyis provided with the valve cover; the pilot deflation electromagnetic valve is arranged on the valve cover; the other side of the valve body opposite to the pilot deflation electromagnetic valve is provided with the wellhead connector; the side of the valve body in the wellhead connector is provided with a microphone; the valve body is further provided with a pressure sensor, a pressure gauge, a micro-sound sensor, a manual pressure relief valve and the inflation / deflation electromagnetic valve. A main valve rod is designed to be a stepped type, so that gas in a well and gas in a gas storage chamber both can be used as the gas sources for pushing the valve rod to move, and the implosion and explosion manners are combined together; the two gas sources are connected with a control cavity bydamping holes for inflating the control cavity, so that gas resetting of the main valve rod can be realized, continuous transmission also can be realized when PMW (pulse width modulation) signals aresupplied to the pilot deflation electromagnetic valve; the shortage that the traditional implosion / explosion air gun has a complicated structure and is difficult to assemble and disassemble is solved.

The invention relates to a continuous emission mechanism of a haemorrhoids loop ligature device.The continuous emission mechanism is characterized by comprising a fixed pipe (1), a pushing pipe (2) and an emission trigger (3), the fixed pipe (1) is sleeved with the pushing pipe (2), the tail of the pushing pipe (2) is connected with the emission trigger (3) through a pushing rod (4), a compressed spring (5) is arranged on the pushing rod (4), and the pushing pipe (2) can move along the fixed pipe (1) back and forth by triggering the emission trigger (3); a fixed threaded rod (6) is arranged on the head of the fixed pipe (1), pushing threaded rods (7) are arranged on the head of the pushing rod (2), multiple slide grooves are uniformly formed in the fixed threaded rod (6), and the pushing threaded rods (7) are embedded into the slide grooves in the fixed threaded rod (6).The fixed threaded rod and the pushing threaded rods which are embedded inside and outside are adopted in the head of the loop ligature device to continuously emit rubber rings, and the haemorrhoids loop ligature device is suitable for treating different patients.
