Abstract
The invention discloses a self-actuated regulator thermal bulb structure. By adopting the self-actuated regulator thermal bulb structure, the insertion depth of a measured object can be adjusted. The self-actuated regulator thermal bulb structure comprises a thermal bulb body, a capillary tube and a measuring bellow. A cavity is formed in the thermal bulb body. One end of the capillary tube extends into the cavity. The other end of the capillary tube is connected with the measuring bellow. One end of the thermal bulb is provided with an extension tube. The extension tube is formed by connecting a plurality of detachable branch tubes in an end-to-end mode. A via hole is formed in each branch tube. The via holes are communicated with the cavity. The capillary tube penetrates through the via holes. A threaded section is arranged on the periphery of each branch tube. A bolt is connected to one of the threaded sections. An annular connector used for mounting of the measured object is connected to the outer side of the bolt.
Description
Technical field
The present invention relates to self-operated regulator technology, be specifically related to a kind of self-operated regulator thermometer bulb structure.
Background technique
Self-operated regulator utilizes the feedback signal (pressure, pressure reduction, temperature etc.) of output terminal, is delivered to actuator and drives flap to change the aperture of valve, reach the object regulating pressure, flow, temperature by signal tube.Self-operated regulator can automatically regulate relative to manual modulation valve, and does not need external impetus.The basic structure of self-operated regulator comprises sensing element, pilot valve, actuator and controlling mechanism.At present, sensing element mainly comprises diaphragm, ball float and thermometer bulb, wherein diaphragm is mainly for detection of pressure, ball float is mainly for detection of buoyancy, thermometer bulb is mainly used in the detection of temperature, the main structure of existing thermometer bulb comprises for being inserted into by the thermometer bulb body in the thing of side, extend into the capillary tube of sensed pressure change in thermometer bulb body and the measuring bellow for the change of the pressure of perception being passed to pilot valve, filling liquid or gas in thermometer bulb body, when measured article temperature variation, the volume of the intrinsic gas of thermometer bulb or liquid will change, the pressure simultaneously acted on the capillary will change, the temperature variation of measured article is measured by the change of this pressure.But existing thermometer bulb structure often has the following disadvantages: its degree of depth be inserted in measured article cannot regulate, therefore cannot regulate insertion depth according to different measured article, to reach best measurement effect.
Summary of the invention
The invention is intended to the self-operated regulator thermometer bulb structure of the degree of depth that a kind of adjustable insertion measured article is provided.
Self-operated regulator thermometer bulb structure in this programme, comprise thermometer bulb main body, capillary tube and measuring bellow, in thermometer bulb main body, there is cavity, capillary tube one end extend in cavity, the other end of capillary tube is connected with measuring bellow, be provided with in one end of thermometer bulb main body and draw long tube, draw long tube to be formed by multiple dismountable end-to-end of being in charge of, each being in charge of interiorly all has via hole, described via hole communicates with cavity, capillary tube is through described via hole, thread section is equipped with in each periphery be in charge of, a thread section is connected with bolt wherein, bolt is externally connected with the joint for the ring-type of installing with measured article.
The invention has the advantages that: be provided with in one end of thermometer bulb main body and draw long tube, and draw long tube and formed by multiple dismountable end-to-end of being in charge of, thread section is equipped with in each periphery be in charge of, a thread section is connected with bolt wherein, bolt is externally connected with the joint for the ring-type of installing with measured article, said structure designs, when needing to regulate thermometer bulb main body to insert the degree of depth of measured article according to measured article difference, as long as pull down or install being in charge of of requirement, then bolt on the place of being in charge of specified connects, jointing again on bolt, be installed together by joint and measured article.
Further, metal bellows is provided with at described extracapillary.Due in use, capillary tube is easily bruised, and therefore must be protected, and can be played the effect of protection by metal bellows to capillary tube.
Further, between bolt and joint, there is gap, in described gap, be filled with asbestos layer.Asbestos layer is used for the use of the sealing between thermometer bulb main body and measured article.
Further, the clip of ring-type is provided with in the periphery of asbestos layer.Clip is for compressing the asbestos packing in asbestos layer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: thermometer bulb main body 1, capillary tube 2, clip 3, joint 4, bolt 5, metal bellows 6, draw long tube 7, asbestos layer 8, measuring bellow 9.
Embodiment is substantially as shown in Figure 1: the self-operated regulator thermometer bulb structure of the present embodiment, thermometer bulb main body is made with seamless steel pipe usually, and one end cover plate of thermometer bulb is welded, to form cavity, capillary tube is by copper or the cold drawn weldless tube formed of steel, in order to transmission of pressure.
The present embodiment is provided with at the other end of thermometer bulb main body and draws long tube, draw long tube by being formed by multiple dismountable end-to-end of being in charge of, the present embodiment selects two to be in charge of for example is described, each being in charge of interiorly all has via hole, via hole communicates with cavity, capillary tube one end extend in cavity, and capillary tube is through via hole.The present embodiment abrades in use in order to prevent capillary tube, is provided with metal bellows at extracapillary.
The present embodiment is equipped with thread section in each periphery be in charge of, and a thread section is connected with bolt wherein, and bolt is externally connected with the joint for the ring-type of installing with measured article.Between bolt and joint, there is gap, in gap, be filled with asbestos layer, be provided with the clip of ring-type in the periphery of asbestos layer.
In the present embodiment, the other end of capillary tube is connected with measuring bellow, and the pilot valve of actuator or manipulation actuator that the pressure that measuring bellow produces for being varied with temperature by working medium in the closed system of thermometer bulb main body and capillary tube composition passes to self-operated regulator gets on.Joint between capillary tube and measuring bellow be provided with supporting termination, supporting termination periphery be provided with flange, flange has tapped hole, for other anatomical connectivity.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
