Abstract
The utility model provides a self-sealing type pressure gage joint. The self-sealing type pressure gage joint comprises a cylinder body; an inner cavity is arranged at the middle of the cylinder body; a first step and a second step are formed at two ends of the inner cavity; an inner screw thread is machined at one end of the cylinder body at the direction of the first step, so that a first connector can be formed; a screw thread is machined at the other end of the cylinder body, so that a second connector can be formed; a sealing component composed of a sealing head and a sealing rod is arranged in the inner cavity; an end surface of the sealing head is a hemispherical protruding surface; the diameter of the section of the hemispherical protruding surface is greater than the inner diameter of the first connector; the sealing component is provided with a spring; and the spring is pressed between the sealing head and the second step. The self-sealing type pressure gage joint of the utility model is simple in structure and can realize self sealing. With the self-sealing type pressure gage joint adopted, a pressure gage can be still successfully disassembled when a stop valve of the pressure gage is not completely closed, and liquid leakage can be prevented, and pipeline maintenance operation can be facilitated.
Description
Technical field
The utility model relates to hydraulic machinery technical field, particularly relates to a kind of joint of Bonding pressure table.
Background technology
Hydraulic system will be installed a lot of tensimeters, in order to show and conveniently to record the pressure of hydraulic system.At manometric front end, must arrange and control gate valve and the gate valve for bleeding off pressure, or use the Combined manual stop valve that there is control and bleed off pressure two kinds of functions.Because manometric screw thread is different with the thread forms that is connected stop valve, conventionally can adopt meter connector to connect.Current meter connector only has connection function, and when needs are changed tensimeter, the stop valve of necessary closing presure table, if manometric stop valve can not be closed tight because damaging, need to could change tensimeter by the emptying of whole pipeline flow process, has increased extra work burden.
Utility model content
The purpose of this utility model is to provide a kind of self-sealed pressure tapping, can be after dismounting downforce table, and joint is realized self sealss, and leakage while preventing that stop valve is not closed completely, is convenient to pipeline and safeguards.
The technical solution of the utility model is: a kind of self-sealed pressure tapping, comprise cylindrical shell, the middle part of described cylindrical shell is provided with inner chamber 3, two ends at inner chamber 3 form first step 2 and second step 4, cylindrical shell forms the first connector 1 at one end of first step direction machining internal thread, and other end machining screw forms the second connector 5; In described inner chamber 3, be provided with the seal being formed by seal head 8 and seal bar 6, the end face of described seal head 8 is semisphere convex surface, its diameter of section is greater than the internal diameter of the first connector, and spring 7 is installed on described seal, and described spring 7 is pressed between described seal head 8 and second step 4.
Further, the screw thread of described the second connector 5 is external thread.
Principle of work of the present utility model is: after dismounting downforce table, the seal head of packoff is pressed on first step under the effect of spring, has realized between inner chamber and the endoporus of the first connector and having sealed, and prevents leakage; Install after tensimeter, manometric screw thread mounting head is depressed seal head, and the endoporus of inner chamber and the first connector is communicated with, gauge measurement pipe system pressure.
The utility model is simple in structure, can realize self sealss, in the situation that stop valve for pressure gauge is not closed completely, still can unload smoothly tensimeter, prevents leakage, has facilitated pipeline attended operation.
Accompanying drawing explanation
Fig. 1 is the utility model structure cut-open view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described.
As shown in Figure 1, self-sealed pressure tapping of the present utility model, agent structure is cylindrical shell, at the middle part of cylindrical shell, be provided with inner chamber 3, the diameter of inner chamber 3 is greater than the internal diameter at cylindrical shell two ends, at the two ends of inner chamber, forms first step 2 and second step 4, cylindrical shell is at one end machining internal thread of first step 2 directions, form the first connector 1, other end machining screw forms the second connector 5, the second connectors 5 and preferably adopts external thread structure; In described inner chamber 3, be provided with the seal being formed by seal head 8 and seal bar 6, seal head 8 is fixedly connected with seal bar 6, also can be one, the end face of described seal head 8 is semisphere convex surface, its diameter of section is greater than the internal diameter of the first connector 1, in the seal bar 6 of seal, cover has spring 7, and described spring 7 is pressed between described seal head 8 and second step 6.
