But in this ball valve, for thermometer is installed, separately establish a through hole on valve body, lengthened the length of valve body, thermometer gauge outfit has also occupied certain space, and therefore, this class ball valve takes up room larger, use inconvenient.
Bimetallic thermometer is a kind of Site Detection instrument of measuring temperature, can directly measure various medium temperatures.The main element of bimetallic thermometer be two or more metal film stacks of use force together composition multilayered metal film, utilize the different metal principle work that degrees of expansion is different in the time of temperature change.In the time of the expanded by heating of multilayered metal film one end, drive pointer rotation, dial plate is showing temperature value just.
For example, the Chinese utility model patent specification (patent No.: 93200064.9, notice of authorization number: CN2148319Y) disclosed a kind of Double metal bar type thermometer (bimetallic thermometer), comprise top cover, gland, trim ring, protecting jacket, indicator, there is the dial plate of center hole, mandrel, helical bimetallic temperature sensor, on dial plate, there is temperature scale mark, also have a tube wall upper end to have the sleeve pipe of step, insert in dial plate center hole sleeve pipe upper end, and rivet with dial plate, lower end is fixedly connected with helical bimetallic temperature sensor one end, mandrel is through sleeve pipe, helical bimetallic temperature sensor and dial plate center hole, its upper end is fixedly connected with indicator, lower end is fixedly connected with the other end of bimetallic temperature sensor, protecting jacket bottom tubular portion is one, the indicator connecting together, mandrel, helical bimetallic temperature sensor, sleeve pipe, dial plate is arranged in protecting jacket.
Existing bimetallic thermometer is all similar above-mentioned structure.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of ball valve with thermometer of compact structure.
The purpose of this utility model can realize by following technical proposal:
A kind of ball valve with thermometer; the valve ball that comprises valve body, make by metallic material and valve rod; described valve ball is positioned at valve body; the lower end of described valve rod is fixed on valve ball, and the upper end of described valve rod passes valve body, it is characterized in that; in described valve rod, be the mounting hole of bar shaped along being axially arranged with of valve rod; this ball valve also comprises the bimetallic thermometer fixing with valve rod, the protecting jacket that described bimetallic thermometer comprises dial plate and arranges perpendicular to dial plate, and described protecting jacket inserts in mounting hole.
Because the material of valve ball and valve rod is metal; in the time that fluid is flowed through ball valve, the heat of fluid is delivered to the protecting jacket place of bimetallic thermometer, the bimetal temperature distortion in protecting jacket through valve ball, valve rod; drive pointer in dial plate to rotate, the dial plate of bimetallic thermometer just can show the temperature of fluid.Due in this valve, thermometer is arranged in valve rod, makes the overall structure of this ball valve comparatively compact, does not affect the length of valve body.
In the above-mentioned ball valve with thermometer, the protecting jacket of described bimetallic thermometer reclines mutually with valve rod mounting hole madial wall.Protecting jacket reclines mutually with valve rod, makes the temperature that bimetallic thermometer can more accurate reacting fluid.
In the above-mentioned ball valve with thermometer, the upside of described valve body is provided with handwheel, and described handwheel comprises ringwise assembly department, the shape of described assembly department and the shape of dial plate matches and dial plate is positioned at assembly department.Dial plate is arranged in handwheel assembly department, increases the stability of bimetallic thermometer index dial structure, handwheel also plays the effect of protection dial plate, makes dial plate in use not fragile.
In the above-mentioned ball valve with thermometer, described handwheel also comprises and is positioned at assembly department downside and tubular limited part, and described limited part madial wall has convex shoulder, and described valve rod upper side has confined planes, and described convex shoulder reclines mutually with confined planes.Like this, make handwheel and valve rod circumferentially fixing.In the time rotating handwheel, because the confined planes on convex shoulder and valve rod in limited part leans, handwheel can be with ovable valve stem to rotate.Confined planes on convex shoulder and valve rod in handwheel is set, makes handwheel can be with ovable valve stem to rotate, avoid using bimetallic thermometer band ovable valve stem to rotate so that bimetallic thermometer stressed excessive and damage.
In the above-mentioned ball valve with thermometer, described valve rod upper end outer side surface has annular groove, is provided with back-up ring and back-up ring and is positioned at the convex shoulder upside of handwheel limited part in described annular groove.After handwheel is arranged on valve rod, set up back-up ring, make stable being fixed on valve rod of handwheel energy, increase the stability of this ball-valve structure.
In the above-mentioned ball valve with thermometer, the outer side surface of the assembly department of described handwheel is arranged with handwheel sleeve in the form of a ring, and described handwheel sleeve outer side surface is evenly distributed with multiple depressed parts for gripping.In the time that operator rotate handwheel, operator's finger embeds the depressed part of handwheel sleeve and rotates handwheel.Be provided with the handwheel sleeve of depressed part, easy-to-operat.
In the above-mentioned ball valve with thermometer, the top of described handwheel sleeve has the bulge loop inwardly stretching out, and described bulge loop is positioned at dial plate upside.Because bulge loop upper side position is higher than dial plate, bulge loop can play a protective role on dial plate, avoids dial plate to damage.
In the above-mentioned ball valve with thermometer, described handwheel assembly department outer side surface has some projections, has and the recess of protruding relative set on the madial wall of described handwheel sleeve, and described projection embeds in recess.Recess on projection and handwheel sleeve on handwheel is set, and what make that handwheel sleeve can be comparatively stable fixes with handwheel, improves the stability of this ball-valve structure.
In the above-mentioned ball valve with thermometer, the upside of described valve body has the limiting stopper one of protrusion, and described handwheel limited part lower end has the limiting stopper two of protrusion, in the time of hand wheel rotating described in limiting stopper one can lean with limiting stopper two.Limiting stopper one and limiting stopper two are set, and easy-to-operat personnel know the switching situation of ball valve.Generally, in the time of ball valve standard-sized sheet and complete shut-down, limiting stopper one and limiting stopper two all can lean.
In the above-mentioned ball valve with thermometer, between described valve rod and valve body, there is stuffing box packing, on described valve rod, be arranged with pressure cap in the form of a ring, described pressure cap be connected with valve body screw thread and the lower end abutment of pressure cap in stuffing box packing.Pressure cap and stuffing box packing are set, increase the sealing between valve rod and valve body.Pressure cap also plays an effect, exactly valve rod is positioned on valve body, avoids valve rod to come off from valve body.
Compared with prior art, in this ball valve with thermometer, the protecting jacket of bimetallic thermometer is positioned at valve rod inside, makes the structure of this ball valve more compact, takes up room less.
