Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of resistance minimum, can measure different medium, and structure is simple, easy to maintenance, a kind of S bend pipe bending flowmeter of long service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of S bend pipe bending flowmeter, comprise straight tube, straight tube center section is provided with bend pipe, be welded with malleation in the middle of the side that bend pipe radian is large and measure laminate, be welded with negative pressure in the middle of the side that bend pipe radian is little and measure laminate, malleation measures laminate and negative pressure and measures in laminate and be connected with needle-like stop valve, needle-like stop valve connects disk type condenser, disk type condenser connects pressure guiding pipe, needle-like stop valve is provided with in the middle of pressure guiding pipe, pressure guiding pipe end is connected with threeway plug valve, and threeway plug valve connects differential pressure transmitter.
Further improvement of the utility model is: described straight tube is constituted by middle bend pipe and levels off to the horizontal pipe of 180 °.
Further improvement of the utility model is: described straight tube and bend pipe are generally level and install, and described differential pressure transmitter should be arranged on the below of bend pipe.
Further improvement of the utility model is: must be arranged on above Bending Tube Sensor if field condition is differential pressure transmitter, pressure guiding pipe need be installed downwards, and then gradual turning upwards.
The utility model compared with prior art has the following advantages:
Without any choked flow piece in elbowmeter straight tube and bend pipe, medium is relative with bend pipe smooth and easy, level and smooth by winding pipe flow rate timing straight tube, is not easy to cause excessive wear; Malleation measures laminate and negative pressure and measures laminate and be fixed on bend pipe by the mode of welding, largest benefit is that safety is with reliable, especially can solve the incidental evaporating, emitting, dripping or leaking of liquid or gas problem when measuring the such special media flow of such as high temperature, high pressure steam, simultaneously directly welded type installation can make in-site installation more convenient, more economically, more reliable, a little repair; Needle-like stop valve have structure simple, lightweight, easy to maintenance, open and close rapidly, sealing surface is not easy to wear, scratch, sealing is better, the life-span is long feature, the main high temperature fluid erosion of high pressure can be born simultaneously; Disk type condenser is convenient to be measured steam; The installation of pressure guiding pipe makes its environmental suitability and antijamming capability improve further, contributes to the environmental suitability strengthening elbowmeter; Threeway plug valve can blowdown, blowback, prevent blocking; Differential pressure transmitter is one of transducing unit that current antijamming capability is the strongest, and it is round-the-clock measurement instrument that differential pressure transmitter is known as, and it is also very good for the adaptability of environment; Straight tube is constituted by middle bend pipe and levels off to the horizontal pipe of 180 °, and the drag losses produced only has very little numerical value, and measuring accuracy is high, belongs to energy-saving flow measurement device; Straight tube and bend pipe are generally level and install, and differential pressure transmitter should be arranged on the below of bend pipe, and the gas discharging in pressure guiding pipe can be made to get back in straight tube.
accompanying drawing illustrates:
