Abstract
The utility model relates to a gas trap valve for a pipeline, which is suitable for the automatic air exhaust of various low pressure liquid conveying pipelines, particularly hot-water heating systems and household traditional radiators. The utility model is composed of a joint, a valve body, a valve core, a check ring, and a filter screen. A round table on the lower part of the inner wall of the valve body is in sequence provided with the filter screen and the check ring; the valve core with a conic body is positioned above the check ring; the joint is positioned in the valve body and is integrally welded with the upper end of the valve body in a sealing way. The utility model has the advantages of simple and compact structure, low cost, convenient installation, automatic air exhaust and water seaing, and strong sensitivity and reliability.
Description
The utility model relates to and a kind ofly is applicable to that various low pressure liquid-transport pipe-line discharge cycle working procedure produce, and influence the gas of normal liquid conveying; Especially be applicable to the hot-water heating heating system of central heat supply and the automatic vent of family expenses soil heating installation.Belong to pipeline float stop valve manufacturing technology field.
Report according to Chinese patent literature, be used to solve the exhausting problem of various low pressure liquid-transport pipe-line normal circulation at present, particularly the automatic control pressure vent of the hot-water heating heating system of central heat supply and family expenses soil heating installation is not rarely seen, as utility model patents such as disclosed 90220882.9, No. 90218225.0 of Chinese patent communiques, their design is complicated and simple to differ, and structure is different.The problem that exists is: or complex structure, manufacturing cost height, or sensitivity is low, poor reliability, have in addition inconvenience is installed, make to apply to be subjected to very big influence.
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of simple and compact structure is provided, and manufactures easyly, with low cost, and automatic vent is stable and reliable for performance and install and use automatic pipeline vapor cock very easily.
Goal of the invention of the present utility model can be achieved by the following technical programs: this pipeline vapor cock that is applicable to various low pressure liquid-transport pipe-line exhausting air, form by spool 3, check ring 4 and the filter screen 5 of joint 1, valve body 2, band cone.Filter screen 5 and check ring 4 are housed on the round platform of valve body 2 inwall bottoms successively, the spool 3 of band cone place check ring 4 above, joint 1 is loaded among the valve body 2, and is welded as a whole with the sealing of the upper end portion of valve body 2.Evenly be provided with the exhaust port 7 more than at least 2 on the spool 3 of band cone.The outer wall of valve body 2 bottoms has tapering simultaneously, and is shaped on screw thread.
The utility model advantage compared with prior art is: the one, since simple and compact for structure, manufacture conveniently, with low cost; The 2nd, owing to adopt the seal welding mode of the design of float directly controlled type, valve body 2 and joint 1, make its automatic vent highly sensitive, stable and reliable for performance, test shows, in various low pressure liquid-transport pipe-lines, adopt this practicality, novel because gathering steam in the blowdown piping automatically at any time makes whole circulation system unblocked, particularly, improved the heating heat release rate greatly for hot-water heating heating system and family's soil heating installation.Next is easy to install, does not need professional technique.
Accompanying drawing and drawing explanation:
Figure of description is an overall structure schematic representation of the present utility model;
Wherein: 1-joint 2-valve body 3-spool 4-check ring
5-filter screen 6-tapered thread 7-exhaust port
Embodiment: the 5th part of this specification and in conjunction with Figure of description to have provided complete embodiment of the utility model.So no longer repeat here.If the exhaust port on the utility model spool 3 is set to 3,4,5 ..., just can constitute other a plurality of embodiments of the present utility model.Make the utility model and remove joint 1 and valve body 2 employings 20
#Outside the steel, spool 3 adopts nylon material, and filter screen selects for use zinc plated mild carbon steel silk cloth to make.The little mounting type head-up that the utility model must adopt vertical type is installed in addition, on the heating installation main pipe of promptly directly valve body 2 external taper screw threads being packed into or user's radiator exhaust port place.Simultaneously can enter container or indoor and outdoor as required at microcephaly's attaching plastic tube of valve body, with humidity in the conditioning chamber, not need the user to align during use, when gas was arranged, the steam body was discharged automatically by the exhaust port 7 on the spool 3.After gas had been arranged, flowing liquid floated nylon spool 3, in the taper hole of the top insertion joint of the circular cone on the spool 31 central authorities, realized closing automatically.When system pressure reduced promptly to produce gas, nylon spool 3 fell after rise by deadweight, and valve body is opened automatically simultaneously, begins automatic vent again, and circulation so repeatedly realizes automatic vent and closes apolipsis liquid.
