Referring to fig. 1-7, the present invention provides a technical solution:

a drain valve with a detachable valve core comprises an upper valve body 1, wherein the upper valve body 1 is of a hollow structure, two sides of the upper valve body 1 are respectively provided with a fluid inflow channel 10 and a fluid outflow channel 11, a filter screen 12 fixedly connected with the upper valve body 1 is arranged in the upper valve body 1, the bottom of the upper valve body 1 is provided with a lower valve body 2, the lower valve body 2 is locked and fixed on the upper valve body 1 through a bolt and a nut 5, the lower valve body 2 is of a hollow structure, one side of the lower valve body 2, which is positioned at the fluid outflow channel 11, is provided with a valve seat 20, the bottom end of the valve seat 20 is provided with a through hole, a water drainage piece 22 is arranged in the through hole, the top of the water drainage piece 22 penetrates through the inside of the lower valve body 2, the top of the water drainage piece 22 is provided with a first water drainage channel 220, the tail end of the water drainage piece 22 is provided with a second water, the inside a plurality of support columns 21 that are equipped with of lower valve body 2, the inside top that is located support column 21 of lower valve body 2 is equipped with globular case 6, and the top of going up valve body 1 is equipped with valve gap 3, and valve gap 3 passes through screw 4 locking and fixes on last valve body 1.

In this embodiment, the bottom of going up valve body 1 and the top of lower valve body 2 all are equipped with heavy groove, and are equipped with the first sealing washer 7 rather than the looks adaptation in the heavy groove, and the top of going up valve body 1 is equipped with the recess, and is equipped with the second sealing washer 8 rather than the looks adaptation in the recess, prevents that the inside condensate water of trap and steam from spilling over.

In addition, spherical case 6 is the hollow spheroid of stainless steel, and the top of spherical case 6 is less than filter screen 12, guarantees that spherical case 6 can rise and float along with the water level of condensate water rises, opens the first drainage channel 220 at drainage 22 top, and fluid inflow passageway 10 runs through to supreme valve body 1 inside for mixed fluid can get into inside the trap, and second drainage channel 221 is linked together with fluid outflow passageway 11, makes the inside condensate water of trap can follow fluid outflow passageway 11 and flow out.

Further, the number of the support columns 21 is at least two, the support columns 21 and the drainage pieces 22 are arranged at equal intervals, the spherical valve core 6 is supported on the tops of the support columns 21 and the drainage pieces 22, and the contact points of the support columns 21 and the drainage pieces 22 and the spherical valve core 6 are equal in height, so that when the condensed water in the drain valve is not enough to float the spherical valve core 6, the spherical surface of the spherical valve core 6 can close and seal the first drainage channel 220 on the top of the drainage pieces 22.

Specifically, the valve seat 20 is located below the liquid level of the condensed water, and can form a water seal to prevent the leakage of steam during the first issue of the book.

When the drain valve with the detachable valve core is used, workers can install the drain valve in a steam pipeline for use; mixed fluid in the steam enters the drain valve, and condensed water is filtered and dripped by the filter screen 12 and gradually accumulated at the bottom of the lower valve body 2; when the water level of the condensed water gradually rises to be enough to float the ball-shaped valve core 6, the valve is opened, the condensed water flows in from the first drainage channel 220 and then flows into the fluid outflow channel 11 through the second drainage channel 221 to be discharged; along with the drainage of the condensed water, the ball-shaped valve core 6 gradually returns to the bottom, the first drainage channel 220 is blocked and sealed again, and a new period is started; when the steam trap goes wrong, the main valve of the steam pipeline is closed, the bolt and the nut 5 are loosened, the upper valve body 1 and the lower valve body 2 are separated, the interior and the spherical valve core 6 are inspected, meanwhile, the locking piece 23 can be detached, the drainage piece 22 is taken out to inspect the drainage piece, the drainage piece is assembled after the problem is solved, the locking piece 23 and the bolt and the nut 5 are locked, and finally, the main valve of the steam pipeline is opened, so that the steam pipeline continues to work.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
