Abstract
The utility model discloses a pneumatic valve case structure, it contains one valve rod (1), and this valve rod (1) whole to be hollow tubular structure, the one end of valve rod (1) is provided with out air cock (2), and the round is outwards extended rather than endocentric boss (3) in near of this air cock (2), valve rod (1) other end pass and link to each other with locating lever (5) rather than clearance sliding fit valve barrel (4), the outer disc department of valve barrel (4) is provided with the round external screw thread, several and valve rod (1) inside communicating air vent (6) have been offered to the tip of locating lever (5), the bottom of locating lever (5) links to each other with case (7), the bottom of case (7) is outwards extended one and can be connect complex location boss (8) with return spring set. The utility model relates to a rationally, convenient to use lays hitting for a long time of counter weight ring, and the valve rod of pneumatic valve case is difficult to take place to warp to the life of pneumatic valve case has been prolonged at to a great extent.
Description
Technical field
This utility model relates to a kind of air valve component, is specifically related to a kind of air valve core structure.
Background technology
Air valve core is the critical piece controlling air valve break-make, the most structure of existing air valve core is relatively simple, air-tightness overall during using is poor, when under the long-term impact of counterweight ring, the valve rod of existing air valve core is susceptible to bigger deformation, thus shorten the service life of air valve core to a great extent, the problem that therefore a kind of new technical scheme of exigence solves above-mentioned existence.
Utility model content
This utility model purpose is to provide a kind of air valve core structure, and it can efficiently solve the problem in the presence of background technology.
In order to solve the problem in the presence of background technology, it comprises a valve rod 1, the tubular structure of this valve rod 1 generally hollow, one end of described valve rod 1 is provided with outlet nozzle 2, junction between this outlet nozzle 2 and valve rod 1 extends outward the concentric boss of a circle 3, described valve rod 1 other end is connected through the valve pocket 4 with its clearance sliding fit with location bar 5, a circle external screw thread it is provided with at the periphery of described valve pocket 4, the end of described location bar 5 offers several passage 6 of communicating internal with valve rod 1, the bottom of described location bar 5 is connected with spool 7, the bottom of described spool 7 extends outward one can be socketed, with back-moving spring, the positioning boss 8 coordinated.
Being arcuate structure at described spool 7 and the contact surface of valve pocket 4, the end of described valve pocket 4 is the arcuate structure docked with spool 7.
Owing to have employed above technical scheme, this utility model has the advantages that reasonable in design, easy to use, under the long-term impact of counterweight ring, the valve rod of air valve core is also less likely to occur deformation, thus extends the service life of air valve core to a great extent.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model, below in conjunction with accompanying drawing, embodiment is briefly described.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.
Referring to Fig. 1, this detailed description of the invention is to be achieved by the following technical solutions, it comprises a valve rod 1, the tubular structure of this valve rod 1 generally hollow, one end of described valve rod 1 is provided with outlet nozzle 2, junction between this outlet nozzle 2 and valve rod 1 extends outward the concentric boss of a circle 3, described valve rod 1 other end is connected through the valve pocket 4 with its clearance sliding fit with location bar 5, a circle external screw thread it is provided with at the periphery of described valve pocket 4, the end of described location bar 5 offers several passage 6 of communicating internal with valve rod 1, the bottom of described location bar 5 is connected with spool 7, the bottom of described spool 7 extends outward one can be socketed, with back-moving spring, the positioning boss 8 coordinated.
Being arcuate structure at described spool 7 and the contact surface of valve pocket 4, the end of described valve pocket 4 is the arcuate structure docked with spool 7.
Owing to have employed above technical scheme, this detailed description of the invention has the advantages that reasonable in design, easy to use, under the long-term impact of counterweight ring, the valve rod of air valve core is also less likely to occur deformation, thus extends the service life of air valve core to a great extent.
Last it is noted that above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit；Although being described in detail this utility model with reference to previous embodiment, it will be understood by those within the art that, the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
Claims (2)
1. an air valve core structure, it is characterized in that it comprises a valve rod (1), the tubular structure of this valve rod (1) generally hollow, one end of described valve rod (1) is provided with outlet nozzle (2), junction between this outlet nozzle (2) and valve rod (1) extends outward the concentric boss of a circle (3), described valve rod (1) other end is connected through the valve pocket (4) with its clearance sliding fit with location bar (5), a circle external screw thread it is provided with at the periphery of described valve pocket (4), the end of described location bar (5) offers several passage (6) of communicating internal with valve rod (1), the bottom of described location bar (5) is connected with spool (7), the bottom of described spool (7) extends outward one can be socketed, with back-moving spring, the positioning boss (8) coordinated.
