Description
Technical field
The invention relates to a kind of combination has manometric thermometer, and it can obtain a combined instrument that is combined by spring-tube pressure gauge and bimetal type thermometer.Pressure scale and temperature scale are separately positioned on the marking panel with rectangle or circular enclosure.The combination that provides a kind of divergence type has manometric thermometer, and wherein separate at the center of pressure pointer and temperature pointer.The combination that provides a kind of mating type has manometric thermometer, and wherein pressure pointer and temperature pointer are based on same central point and use together.It is moving and obtain that above-mentioned two structures are based on double-handle and two-track.
Background technology
In general, the size of capacity, speed, vibration, temperature, pressure, calorie and length or physical state all are based on certain data (numerical value) and measure, with certain measuring instrument records and demonstration.
Surveying instrument as the pressure of a kind of energy measurement liquid or gas or gravity, mercury manometr with certain counterweight and title is arranged, the spring-tube pressure gauge of flexible member with elastic force and the title that has relevant static load is arranged and utilize physical phenomenon to change the electric resistance manometer of realizing based on aperture and pressure.
In above-mentioned pressure gauge, it is the most extensive that spring-tube pressure gauge is employed, because it can directly read the corresponding scale value of pressure institute, and uses simple.
In addition, as thermometer, usually be used from the oxidation and the coating tool of semiconductor fabrication process with above-mentioned pressure gauge one, the thermal vibration thermometer that can use the power measurement temperature is arranged, thereby this electric power is encapsulated coil that forms by the end that connects two kinds of metals and the temperature that changes two tie points to be produced, mercury thermometer is the thermal expansion that utilizes mercury, and the realization of temperature sensor is that to utilize the temperature range be widely used in its energy measurement of industrial purposes be that 400 ℃-1400 ℃ thermoelectricity connects.
Yet in above-mentioned thermometer and pressure gauge, thermometer separates installation with pressure gauge.Therefore, for thermometer and pressure gauge, all need an additional installing space.In addition, because they are to separate to install, so can not while detected temperatures meter and pressure gauge.The pressure and temperature of liquid should be measured simultaneously in the water pipe, yet its pressure and temperature is measured respectively, so increased error range.Many problems in safeguarding surveying instrument can cause the inconvenience of measuring operation, and safety problem is arranged, so but reduced practicality.
Summary of the invention
Therefore, one object of the present invention is exactly to overcome above-mentioned traditional problem.
Another object of the present invention provides the multiple measurement instrument of a kind of gaging pressure simultaneously and temperature, promptly uses a surveying instrument while gaging pressure and temperature on same point.Provide the double-handle that is connected on the different circuits, so as between pressure and temperature without any interference.The pressure and temperature pointer is shared.Use can reach the two-track of accurate indicated value to be moved, and realizes the purpose that the present invention is desired thus.
To achieve the above object, provide the multiple measurement instrument of a kind of gaging pressure simultaneously and temperature, wherein the pressure and temperature pointer is based on that divergence type and mating type realizes, on portion's structure and the parts difference is arranged within it because of the method for indicating based on force value indication and temperature value.
In order to arrive above-mentioned purpose, the combination that provides a kind of divergence type has manometric thermometer, comprises a cover of gaging pressure and temperature therein.Thermometer comprises that a bimetallic devices and the upper outside with feeler that is connected with temperature pointer 11 meshes also the fixedly double-handle of process chamber.Pressure gauge comprises a jack that passes thermometer double-handle bottom, survey the pressure of liquid and transmit the pressure of liquid, bourdon tube is attached on the jack and based on pressure and moves, two-track kinetic energy enough greatly amplifies cooperate between spring and the bourdon tube little and moves, the indicated pressure value on display disc of spool cooperating that pressure pointer and two-track are moving.
Double-handle is a path, the pressure and temperature of liquid can be sent on the surveying instrument, realize that based on the method that the hole is set in the heart thick between center pit and outside screw is provided with a hole, with two holes pressure and temperature is realized compatible operations with this in double-handle.Also have another method, the temperature feeler is inserted into the center of double-handle, being to be provided with hole of 1mm size between the outside of feeler and the double-handle inwall around the feeler, so that the circular port around the feeler is used as the path of fluid pressure.
Therefore, have in the manometric thermometer, only used double-handle in the combination of divergence type of the present invention.Do not adopt two-track moving.In other words, adopt common two-track moving.
Combination in mating type of the present invention has in the manometric thermometer, and force value and temperature value are realized in a housing.In this thermometer, the feeler with bimetallic devices passes the center of double-handle, and contacts with the liquid of double-handle outside.
Here, bimetallic devices detects the temperature and the reduced and expansion of liquid.Above-mentioned variation is sent to axle, and axle passes the interior diameter of the moving sun gear shaft of two-track, moves the pointer that is connected axle head thus, so just indicated temperature.Compare with the diameter of the temperature feeler that is installed in central part, the diameter of double-handle is greater than 1mm, so that will be used as the path of pressure fluid (model 1) in the slit of the 1mm between the wall of feeler and double-handle.At the center of double-handle a hole is set, a hole is set between center and outside nut.In other words, two holes are set altogether.Hole is the setting of temperature feeler, and another hole is that the path for press rods is provided with, so that realize compatible.
The liquid that passes through in the above described manner moves the pointer of the outside that is connected the moving central gear of two-track, indicated pressure therefrom.
So, have in the manometric thermometer in the combination of mating type of the present invention, adopt double-handle and two-track moving, obtain desirable effect thus.
