Abstract
The utility model relates to a shock resisting pressure gauge for measuring pressure of uncorroded liquid, gas and smoke; mainly comprising a gauge case, a case shell, a case core, a draw rod, a scale, an indicating needle and joints. The utility model is characterized in that a screw type reed pipe and damping medium are arranged in the gauge so that the gauge can correctly measure medium pressure when the measured medium fluctuates with an impact quick change and in a shock environment, and the gauge is provided with a safety device. The utility model has the advantages of convenient installation, low cost, high reliability and stable performance.
Description
The utility model is a kind of shock-proof pressure gauge, is applicable to the pressure of measuring free from corrosion liquid, gas and steam.
At present, the tensimeter great majority that use in the domestic various press equipment belong to ordinarily manometer." industrial automation instrument product sample " that first Ministry of Machine-Building Industry that publishes according to China Machine Press edits and the retrieval of other interrelated data show, ordinarily manometer is divided into the capsule pressure gauge diaphragm manometer, single-coil spring hook gauge and other special pressure tables, capsule pressure gauge is used to the minute-pressure and the negative pressure of the gas measuring air and aldary is not played corrosive attack, it generally is used for air duct more, burner and other similar equipment upper diaphragm tensimeter are applicable to that measurement is to copper, aldary, steel, alloy steel has corrosive attack and the bigger pressure medium of powder degree, the single-coil spring hook gauge then is by measuring system (joint, single-coil spring pipe and gear drive), indicating section (pointer, scale) and housing parts (watchcase) (thin bezel ring, and fixed screw) three parts form, general as friction, measure the non-liquid that solidifies in the environment of top shake, the pressure of gas or steam, more than several tensimeters in use have two big shortcomings, the one, when measuring the pressure of pulsatile impact load medium, the 2nd, when the pressure medium in the fiercer place of measurement environment vibrations, the pressure measurement indication is waved and is not stopped, can't correctly indicate, thereby influence normal measuring accuracy, and tensimeter is extremely short serviceable life in above two kinds of situations.
The purpose of this utility model is the many weak points at above several ordinarily manometers existence, and on the basis of existing individual pen formula bourdon gauges, improve, designed the pressure medium of the fast varying load of a kind of energy measurement pulsatile impact system and the shock-proof pressure gauge that measurement environment shakes the pressure in fiercer place.
The basic configuration of this shock-proof pressure gauge and structure and common single-coil spring hook gauge are similar, mainly form by watchcase, movement, pull bar, scale, pointer and joint, its principal character is with the single-coil spring pipe in the alternative common bourdon gauges of tin-phosphor bronze one circle half dish type spiral reed pipe, tin-phosphor bronze of welding or red copper damper tube connect a slice damping fin at an end of pull bar between end of joint and spiral reed pipe head end, and inject resisting medium in the table chamber.General be lower than under-20 ℃ the working environment select for use silicone oil under working environment more than-20 ℃, to select for use glycerine as resisting medium, whole tensimeter housing is all-sealed, the displacement of spiral reed pipe pipe end chooses 2.5～3.5, ratio of gear then chooses 12～14, linkage magnification system chooses modulus 0.2, the central shaft number of teeth 14, assembly center is apart from 24, according to different amplification ratios, shock-proof pressure gauge is divided into 6MPa by measuring the upper limit, 10MPa, 16MPa, 25MPa, 40MPa, six kinds of specifications of 60MPa, when joint is connected with relevant press equipment pressure source when starting working, under the effect of measured medium pressure, pulsing and having the medium that impacts the speed change at first enters bronze damper tube by joint, impels end generation corresponding elastic deformation--the displacement of spiral reed pipe behind damper tube yoke stream again.Then by the effect of pull bar through the transmission of the gear drive on the movement and amplified again and will on scale, be indicated by measuring pressure by the pointer that is fixed on the wheel shaft; one end of pull bar links to each other with the spiral reed pipe; the other end is except that connecting movement; adding in a slice damping fin table chamber makes pointer can be in steady pendulum state all the time at the environment of vibration behind the injection resisting medium; safe oil sealing is equipped with in the watchcase top; whole tensimeter is played the safeguard protection effect; if because the factors such as hypertonia of measured medium cause watchcase weld seam sealing-off etc. table chamber internal pressure is raise, when the table cavity pressure is increased to 0.15MPa, can wash safe oil sealing pressure release automatically open.
The shock-proof pressure gauge that improves after designing removes the fundamental measurement system that keeps original common single-coil spring hook gauge, outside indicating section and the housing parts, increased the steady pendulum device of damping yoke stream buffering, it is become in pressure medium pulsation speed boosts, remain the pressure measurement indicating correct under release and the vibration environment situation, steady and audible, this shock-proof pressure gauge simplicity of design, economical, durable in use, easy for installation, alternative fully general common bourdon gauges, can use with the press coordinative composition of equipments, the precision that can clearly demonstrate complete machine makes complete machine more perfect, has improved work efficiency greatly.
Accompanying drawing has been represented a specific embodiment of the present utility model.
