Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

It is to be understood that such description is merely exemplary and is not intended to limit the scope of the present invention.

The following describes an integrated nozzle type desuperheating water regulating valve provided by some embodiments of the present invention with reference to the accompanying drawings.

The first embodiment is as follows:

with reference to fig. 1 and 2, the utility model provides an integrated nozzle formula desuperheating water governing valve, including governing valve 100, filler subassembly 200 and drive assembly 300, governing valve 100 includes that upper valve body 110, fixed cover establish water inlet 120, the joint in upper valve body 110 top side at the lower valve body 130 of upper valve body 110 bottom. The regulating valve 100 is a main structure for controlling the fluid, and the upper water inlet 120 can facilitate the flow of the cooling medium to the inside of the upper valve body 110. The packing assembly 200 ensures a good seal at the top of the regulator valve 100 to prevent fluid and other media from leaking over the regulator valve 100. The actuating assembly 300 includes a control rod 310 installed in the upper valve body 110, a valve spool 320 integrally connected to the control rod 310 and located at the bottom end of the control rod 310, and a nozzle 330 installed at the bottom side of the upper valve body 110. The valve body 320 prevents the medium from being discharged from the nozzle 330 when it is engaged with the side surface of the nozzle 330, and loses a force for blocking the nozzle 330 when the nozzle 330 slides downward.

Specifically, the bottom end of the regulating valve 100 is provided with a flow pipe perpendicular to the regulating valve 100, and the nozzle 330 is located in the middle of the inner cavity of the flow pipe. Because the nozzle 330 is located in the middle of the inner cavity of the flow-through pipe, the nozzle 330 can cool the fluid in the flow-through pipe. The structural components of the regulator valve 100 and the drive assembly 300 are structural supports for controlling the cooling operation.

The water inlet 120 extends outwards and is provided with a flange at the end, and the diameter value of the inner wall of the water inlet 120 is equal to that of the control rod 310. The flange is mainly used for connecting the water inlet 120 with external pipelines and conveying media into the upper valve body 110. At the same time, the diameter values are equal to each other, so that the flow rate of the medium in the water inlet 120 and the control rod 310 can be ensured to be the same.

Further, the packing assembly 200 includes a packing gland 210 filled above the upper valve body 110, and a packing material 220 sleeved on the upper valve body 110 and located above the packing gland 210. The packing 220 can ensure that the packing gland 210 is tightly compacted above the regulating valve 100, and ensure good sealing effect above the regulating valve 100.

Example two:

referring to fig. 1 and 2, on the basis of the first embodiment, the control rod 310 includes an upper valve rod 311 and a lower valve rod 312, a connection portion of the upper valve rod 311 and the lower valve rod 312 is movably sleeved, and the upper valve rod 311 is tubular. The upper valve stem 311 is fixed in position in the regulator valve 100, but the upper valve stem 311 and the lower valve stem 312 are movably sleeved, so that when a medium is delivered to the lower portion of the inner cavity of the upper valve body 110, the lower valve stem 312 forces the valve element 320 to slide downward under the action of pressure, thereby facilitating the discharge of the medium through the nozzle 330. After the medium is completely conveyed, the valve core 320 is reset upwards due to the acting force of air pressure balance.

Specifically, the side surface of the valve core 320 is tightly attached to the inner wall of the upper valve body 110, and a gap is left between the valve core 320 and the bottom surface of the inner cavity of the upper valve body 110. Because the two are tightly attached, the sealing effect between the two can be ensured, and the reserved gap can facilitate the downward sliding of the valve core 320.

The utility model discloses a theory of operation and use flow: during the use, the fluid circulates in the flow tube below governing valve 100, when the cooling medium entered into supreme valve body 110 through water inlet 120 inside, the pressure of medium can force lower valve rod 312 activity downwards, make case 320 can move about can supreme valve body 110's the least significant end, the side of case 320 originally with nozzle 330 each other laminate, after case 320 lapse, the below of valve body 110 inner chamber can be filled with rapidly to the medium, and under the effect of pressure, finally outwards discharge through nozzle 330, the medium of discharge is sufficient in the flow tube, in order to realize carrying out the cooling operation to the interior fluid of flow tube.
