Specific embodiment

With reference to the accompanying drawing and specific embodiment, the utility model can be better described.

As shown in Figure 1, a kind of inverted bucket steam trap, including valve body 1, valve deck 2, reverse bucket 3, be equipped in the valve body 1 into Oral cavity 101, water collection chamber 102, outlet plenum 103, are equipped with guide wire 4 in the middle part of the valve body 1,4 both ends of guide wire be opening and It is separately connected entrance cavity 101 and water collection chamber 102, the reverse bucket 3 is set in outside the guide wire 4, the side wall of the guide wire 4 Equipped at least one port 401.At least one port is set by the side wall in guide wire, makes steam and condensate liquid preferentially from logical Water collection chamber is flowed at mouthful, percussion can be formed to reverse bucket to avoid meeting in this way.

The port 401 is four contour and be uniformly arranged on the side wall of guide wire 4.Steam and condensate liquid can be equal Water collection chamber is flowed into from passage port evenly.

Be equipped with check-valves 5 in the guide wire 4, the check-valves 5 be arranged in guide wire 4 bottom and the port 401 Between.When ensure that pipe negative pressure, condensed water will not be flow backwards, and prevent from flowing backwards the harm to system, especially water hammer harm.

As shown in Fig. 2, the check-valves 5 includes check valve body 501, guide holder 502, valve rod 503, the first flap 504, 4 lower end of guide wire is equipped with internal screw thread, and the check valve body 501 is connect with 4 lower thread of guide wire, the check-valves valve Body 501 is threadedly coupled with guide holder 502, and the valve rod 503 is connect with the first flap 504, and the valve rod 503 passes through the guiding Seat 502 and the relatively described company of guide holder 502 axial displacement, are equipped with spring 505 between the guide holder 502 and the first flap 504. It is simple in construction, easy to disassemble and assemble.Mounting groove can be set in 501 rear surface of check valve body, convenient for being rotated by tool It is mounted in guide wire 4.

First flap 504 is up big and down small circular platform type, and the check valve body 501 is equipped with 506 He of access road The inclined-plane being adapted to 504 side of the first flap.When such closure of check ring, sound is small, wears less, good airproof performance.

503 lower end of valve rod is connected with the second flap 507, is equipped between first flap 504 and the second flap 507 Ladder-shaped sealing ring 508 is matched when second flap 507 is located in the access road 506 with 506 gap of access road It closes.Ladder-shaped sealing ring surface is slightly convex in the first flap 504, and ladder-shaped sealing ring 508, which is arranged, can be enhanced leakproofness, while the second valve With 506 clearance fit of access road after the entrance access road 506 of valve 507, the first flap 504 and trapezoidal sealing can be prevented It is not exclusively bonded to form gap between circle 508 and check valve body 501.It is close that ladder-shaped sealing ring 508 also could alternatively be O shape Seal,

The valve rod 503 is integrally formed with the first flap 504, and second flap 507 connects with 503 screw thread of valve rod It connects.When assembling in this way, now by 508 sets of ladder-shaped sealing ring under the first flap 504, then by 507 valve rod of the second flap, 503 screw thread Connection, fixed ladder-shaped sealing ring 508, can be improved production efficiency.It can also be by valve rod 503, the first flap 504 and the second flap 507 it is entire be integrally formed, by the elasticity of ladder-shaped sealing ring 508 itself be inserted in the first flap 504 and the second flap 507 it Between, relatively laborious in this way, efficiency is lower, and also has certain influence to the service life of ladder-shaped sealing ring 508.

The valve deck 2 is detachably connected with the valve body 1, and fluid channel 201 is equipped in the valve deck 2, and the fluid is logical Road 201 is connected to water collection chamber 102 and outlet plenum 103, and valve seat 6 is equipped in the fluid channel 201, is equipped with and hangs below the valve seat 6 Trestle 7 is equipped with hook 301 above the reverse bucket 3, is connected between the hanger column 7 and hook 301 by lever 8, the thick stick Bar 8 is equipped with spool 9, and the spool 9 forms sealing pair with valve deck 2.

Filter screen 10 is equipped in the entrance cavity 101, the filter screen 10 is located at 4 lower section of guide wire.

The valve body 1 is equipped with the entrance 104 of connection entrance cavity 101 and the outlet 105 that is connected to outlet plenum 103, it is described enter Internal screw thread is equipped in mouth 104 and outlet 105.

The foregoing is merely an embodiment of the present invention, are not used to limit the protection scope of the utility model； The protection scope of the utility model is limited by the claim in claims, and all according to equivalent made by utility model Variation and modification, all within the protection scope of the utility model patent.
