Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a take blowdown loose joint relief pressure valve, including valve body 1, 1 upper surface middle part of valve body is slope threaded connection has case 2, the tip threaded connection of valve body 1 has coupling nut 3, the inside joint of one end that valve body 1 is close to coupling nut 3 has filtering component 4, filtering component 4 sets up between valve body water inlet and case 2, the running water that gets into case 2 needs the filtration through filtering component 4, 1 lower surface threaded connection of valve body has with filtering component 4 complex loose joint 5 of slagging tap, it is used for supporting filtering component 4 to slag tap loose joint 5, when needs arrange the sediment, extract and slag tap loose joint 5, the inside impurity of filtering component 4 will be along the jack discharge valve body 1 of slag tap loose joint 5.

Filtering component 4 includes the joint at the snap ring 41 of 1 inner wall of valve body, fixed mounting is at the infiltration cover 42 of snap ring 41 one side and the collar 43 of fixed mounting in infiltration cover 42 one side, one side of collar 43 is fixed with holds bag 45, it is fixed with a sieve section of thick bamboo 46 to hold bag 45 one side, and sieve section of thick bamboo 46 lateral wall is annular array and has seted up a plurality of slag exits 47, be fixed with telescopic link 48 between a sieve section of thick bamboo 46 inner wall and the collar 43 lateral wall, flowing water is when filtering component 4, the inside impurity of flowing water can be filtered earlier on infiltration cover 42, then the impurity on the infiltration cover 42 gets into under the flowing water impact and holds bag 45 insidely, then flowing water sees through a sieve section of thick bamboo 46 and flows out filtering component 4.

In order to increase the contact area between the water seepage sleeve 42 and the flowing water, the diameter of the snap ring 41 is larger than that of the snap ring 41, and the water seepage sleeve 42 is arranged in a frustum shape.

A framework 44 abutting against the inner wall of the accommodating bag 45 is fixed between the side wall of the mounting ring 43 and the side wall of the screen cylinder 46, the framework 44 can expand the accommodating bag 46, the accommodating bag 46 is arranged in a spherical shape, and thus, flowing water forms vortex inside the accommodating bag 46, and impurities stay inside the accommodating bag 46 as much as possible.

The telescopic rod 48 comprises an outer cylinder 481 fixedly connected with the inner wall of the screen cylinder 46, a push rod 482 inserted at the end part of the outer cylinder 481 in a sliding manner, and a spring 483 arranged inside the outer cylinder 481, wherein two ends of the spring 483 are respectively abutted against the side wall of the push rod 482 and the inner wall of the outer cylinder 481, the end part of the push rod 482 is fixedly connected with the mounting ring 43, and the spring 483 can provide a force for the push rod 482 to the inside of the screen cylinder 46, so that the push rod 482 bends the framework 44 through the mounting ring 43, and the framework 44 is convenient to bend and support the accommodating bag 46.

Slag tap loose joint 5 includes the inserted bar 51 with valve body 1 joint, fixed mounting is at inserted bar 51 tip one side jump ring 52 and the first stagnant water circle 53 of joint in inserted bar 51 other end side, jump ring 52 can be with inserted bar 51 joint in valve body 1 bottom, first stagnant water circle 53 can seal the gap between inserted bar 51 and the valve body 1, effectively avoid leaking, the tip of inserted bar 51 extends to valve body 1 inner wall and butt in sieve section of thick bamboo 46 one side, the tip threaded connection of inserted bar 51 has threaded rod 54, the lateral wall joint of threaded rod 54 has second stagnant water circle 55, second stagnant water circle 55 can seal the gap between threaded rod 54 and the inserted bar 51, effectively avoid leaking, user of service need when arranging the sediment outwards extract inserted bar 51 can, inserted bar 51 is extracted to make sieve section of thick bamboo 46 not receive after conflicting, telescopic link 48 extension drives skeleton 44 and straightens, then slag tap 47 and the jack intercommunication of slag tap loose joint 5, it will be along 47 cocurrent flow through the valve body of slag tap 5 jack to hold the inside impurity of bag 45.

And those not described in detail in this specification are well within the skill of those in the art.

During operation, when flowing water passes through the filtering assembly, impurities in the flowing water can be filtered and stay in the accommodating bag 45 and the sieve cylinder 46, so that the impurities in the flowing water are prevented from entering the valve core 2; when needing 4 inside impurity blowdown to filtering component, extract inserted bar 51 and make it break away from the contact with a sieve section of thick bamboo 46, then telescopic link 48 extends under the effect of spring 483, the jack intercommunication at slag notch 47 and inserted bar 51 place this moment, because skeleton 44 straightens and the inside impurity of bag 45 that holds of extension will be along rivers outflow slag notch 47, and through inserted bar 51 installation jack outflow valve body 1, when needing to insert inserted bar 51 once more, need stop supplying water, then telescopic link 48 resets and just can insert inserted bar 51 back, it is the theory of operation of taking blowdown loose joint relief valve to go up.
