Description

Technical Field

[0001] The utility model relates to the technical field of hydrophobic regulating valves, and more particularly to an anti-scouring hydrophobic regulating valve. Background Art

[0002] The steam trap regulating valve is suitable for valves in high-temperature and high-pressure steam trap pipelines. Its basic function is to discharge condensate and steam in the steam system in a timely manner; at the same time, it prevents steam leakage as much as possible to reduce heat loss.

[0003] Since most of the existing valves are manually adjusted, if the valve is closed for a long time and then opened, it may rust. If it is rusted or the operator tightened it too much last time, it will be difficult to open it again. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-scouring hydrophobic regulating valve to solve the problems raised in the above background technology:

[0005] Since most of the existing valves are manually adjusted, if the valve is closed for a long time and then opened, it may rust. If it is rusted or the operator tightened it too much last time, it will be difficult to open it again.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] The anti-scouring hydrophobic regulating valve comprises a valve body, a valve core, a valve stem and a handle, the interior of the handle is fixedly connected to a round tube, and the guide hole in the valve body has a height difference, which can avoid direct scouring of the fluid medium, thereby achieving the purpose of anti-scouring. The interior of the round tube is slidably connected to a force rod, and the force rod helps the operator to better rotate the handle. A first slide groove is provided inside the round tube, and a second slide groove is provided inside the round tube and on one side of the first slide groove. A third slide groove is provided inside the round tube and on the other side of the first slide groove. The second slide groove and the third slide groove are both communicated with the first slide groove, the second slide groove and the third slide groove are parallel to each other, and the first slide groove is perpendicular to the second slide groove and the third slide groove. The interior of the second slide groove is slidably connected to a sliding rod, and the sliding rod is fixedly connected to the force rod, and the first slide groove, the second slide groove and the third slide groove cooperate with the sliding rod to limit the force rod.

[0008] Preferably, the slide rod is made of a magnet. Since the handle and the round tube are both made of iron, the slide rod used to limit the force rod is magnetic and can be directly adsorbed on the round tube, thereby preventing the force rod from sliding by itself.

[0009] Preferably, a strip groove is provided on a side of the inside of the circular tube away from the first chute. The strip groove can prevent foreign matter from entering the circular tube, making it convenient for an operator to clean out foreign matter from the circular tube.

[0010] Preferably, a ball is fixedly connected to the outer end of the force rod away from the sliding rod, and the ball makes it convenient for the operator to push and pull the force rod.

[0011] Preferably, a groove is provided inside the handle, and the groove is used in conjunction with the ball. When the force rod is completely retracted into the round tube, the ball at one end of the force rod will also enter the groove. Due to the presence of the groove, the ball at one end of the force rod will not protrude too much from the handle.

[0012] Preferably, the outer wall of the force rod fits with the inner wall of the round tube. The force rod is a round rod, which can not only slide back and forth in the round tube, but also twist back and forth in the round tube. Since the force rod fits tightly with the round tube, shaking between the force rod and the round tube can be prevented.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The operator pulls out the force rod through the ball, and the slide rod will enter the first slide groove from the second slide groove. Then, the force rod is slightly rotated, and the slide rod will enter the third slide groove. Finally, it is gently pushed back a short distance to control the slide rod to engage with the third slide groove. At this time, the force rod is limited by the third slide groove and the slide rod, and then the operator can rotate the handle through the force rod to prevent the handle from being unable to be turned due to excessive tightening. The force rod can be retracted by reverse operation. Moreover, the force rod is operated by pulling and pulling, which will not take up too much operating space and has low requirements for operating space. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 6 The anti-scouring hydrophobic regulating valve includes a valve body 1, a valve core 2, a valve stem 3 and a handle 4. The handle 4 is fixedly connected to a round tube 5 inside, and a force rod 6 is slidably connected to the inside of the round tube 5. The force rod 6 helps the operator to rotate the handle 4 better. A first slide groove 7 is opened inside the round tube 5, and a second slide groove 8 is opened inside the round tube 5 and on one side of the first slide groove 7. A third slide groove 9 is opened inside the round tube 5 and on the other side of the first slide groove 7. The second slide groove 8 and the third slide groove 9 are both connected to the first slide groove 7, and the second slide groove 8 and the third slide groove 9 are parallel to each other. The first slide groove 7 is perpendicular to the second slide groove 8 and the third slide groove 9. The second slide groove 8 is slidably connected to the inside of the second slide groove 8. The slide rod 10 is fixedly connected to the force rod 6, and the first slide groove 7, the second slide groove 8 and the third slide groove 9 cooperate with the slide rod 10 to limit the force rod 6.

[0024] Furthermore, the slide rod 10 is made of a magnet. Since the handle 4 and the round tube 5 are both made of iron, the slide rod 10 used to limit the force rod 6 is magnetic and can be directly adsorbed on the round tube 5. When the force rod 6 is completely retracted into the round tube 5, it can prevent the force rod 6 from sliding out automatically.

[0025] Furthermore, a strip groove 11 is provided on the side of the inside of the circular tube 5 away from the first chute 7. The strip groove 11 can prevent foreign matter from entering the circular tube 5. The strip groove 11 can facilitate the operator to clean out foreign matter in the circular tube 5.

[0026] Furthermore, a ball 12 is fixedly connected to the outer end of the force rod 6 away from the slide rod 10 . The ball 12 facilitates the operator to push and pull the force rod 6 , and is helpful for the operator to pull the force rod 6 out of the round tube 5 .

[0027] Furthermore, a groove 13 is provided inside the handle 4, and the groove 13 is used in conjunction with the ball 12. When the force rod 6 is completely retracted into the circular tube 5, the ball 12 at one end of the force rod 6 will also enter the groove 13. Due to the presence of the groove 13, the ball 12 at one end of the force rod 6 will not protrude too much from the handle 4, thereby not affecting the operator's hand.

[0028] Furthermore, the outer wall of the force rod 6 fits with the inner wall of the circular tube 5. The force rod 6 is a round rod, which can not only slide back and forth in the circular tube 5, but also twist back and forth in the circular tube 5. Since the force rod 6 fits tightly with the circular tube 5, shaking between the force rod 6 and the circular tube 5 can be prevented, thereby ensuring the overall stability of the force rod 6.

[0029] When the operator pulls the lever 6 out of the way, the lever 6 will be in the first position and the lever 6 will be in the second position, so that the lever 6 can be pulled out of the valve body 5.
