[0026] As mentioned in the background, existing heat pumps have poorly designed steam flow channels, with fixed nozzle and throat sizes and unadjustable flow rates. Furthermore, the actuator-driven valve core can vibrate, whistle, and even break the valve stem during operation.
[0027] In order to solve this technical problem, the utility model provides a novel adjustable steam jet heat pump, which is applied to a steam jet heat pump.
[0028] Specifically, please refer to Figure 1 - Figure 3 The new adjustable steam jet heat pump specifically includes:
[0029] A valve body 1 is provided with a valve core guide sleeve 2 at one inner end of the valve body 1, and a valve core body 3 is movably connected to the interior of the valve core guide sleeve 2 along the axial direction. A first actuator 4 is provided at one end of the valve body 1 close to the valve body 1, and the telescopic end of the first actuator 4 is detachably connected to the valve core body 3;
[0030] A nozzle body 5 is provided inside the valve body main body 1 and at a position opposite to the valve core main body 3. The nozzle body 5 extends from one end of the valve core main body 3 to a position close to the diffuser body 6. The nozzle body 5 is detachably connected to the valve body main body 1, and the end of the valve core main body 3 is plug-connected to the nozzle body 5; a diffuser body 6 is provided at one end of the valve body main body 1 away from the first actuator 4. The diffuser body 6 is detachably connected to the valve body main body 1, and the diffuser body 6 is arranged in a trumpet shape.
[0031] The novel adjustable steam jet heat pump provided by the present invention, through the coordinated design of multiple structures, enables the device to achieve the effect of regulating the steam flow, and the valve core guide sleeve 2 can effectively enhance the guidance and protection of the valve core body 3, thereby effectively reducing the vibration, whistle sound, and even valve stem breakage of the valve stem of the first actuator 4 during operation.
[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] Example 1:
[0034] Please refer to Figure 1 - Figure 3 , a new type of adjustable steam jet heat pump, which includes:
[0035] The valve body 1 has a valve core guide sleeve 2 disposed at one inner end thereof, with a valve core body 3 movably connected thereto along the axial direction. A first actuator 4 is disposed at the end of the valve body 1 proximal to the valve body 1, with the telescopic end of the first actuator 4 detachably connected to the valve core body 3. To facilitate installation or removal of the valve core body 3, a bayonet 8 is provided at the end of the valve core body 3 distal from the nozzle body 5. The valve core body 3 is connected to the telescopic end of the first actuator 4 via the bayonet 8. It can be seen that the valve core guide sleeve 2 protects the valve core body 3. Thus, when the valve core body 3 moves up and down under the thrust of the first actuator 4, the valve core guide sleeve 2 protects it, preventing vibration of the valve core during movement.
[0036] A nozzle body 5 is disposed within the valve body 1, at a position opposite the valve core body 3. The nozzle body 5 extends from the end of the valve core body 3 to a position near the diffuser body 6. The nozzle body 5 is detachably connected to the valve body 1. Specifically, the nozzle body 5 is threadedly connected to the valve body 1, and the end of the valve core body 3 is plug-connected to the nozzle body 5. A diffuser body 6 is disposed at the end of the valve body 1 away from the first actuator 4. The diffuser body 6 is detachably connected to the valve body 1 and is shaped like a trumpet. It can be seen that the nozzle body 5 is mounted on the valve body 1 via a threaded connection, facilitating its installation and maintenance. The nozzle opening of the nozzle body 5 is close to the trumpet-shaped intake port of the diffuser body 6, resulting in low resistance to the flow of the inhaled low-pressure steam and generating greater pressure.
[0037] During the up and down movement of the valve core body 3, a closed air chamber is formed on the inner side of the valve core guide sleeve 2 and in the space away from the valve core body 3. In order to reduce the air pressure of the closed air chamber on the valve core body 3 during the upward movement and the vacuum suction force during the downward movement, a groove 7 is opened on the outer side of the valve core body 3, and the number of grooves 7 is multiple.
[0038] Example 2:
[0039] The novel adjustable steam jet heat pump provided in Example 1 is further optimized, specifically, as follows Figure 4 As shown, a second actuator 11 is provided on the outside of the diffuser body 6 , and the telescopic end of the second actuator 11 extends to the inside of the diffuser body 6 ; wherein, the second actuator 11 is located at the position of the diffuser body 6 where the diameter is the smallest.
[0040] Through the above structural design, the telescopic end of the second actuator 11 is extended into or retracted into the inner side of the diffuser body 6, thereby changing the size of the steam flow space in the diffuser body 6, thereby achieving regulation and control of the steam pressure.
[0041] Example 3:
[0042] The novel adjustable steam jet heat pump provided in Example 1 is further optimized, specifically, as follows Figure 2 As shown,
[0043] A guide groove 9 is provided on the inner side of the valve core guide sleeve 2, and the valve core body 3 is located on the inner side of the guide groove 9. A ventilation groove 10 connected to the guide groove 9 is provided on the outer side of the valve core guide sleeve 2, and the ventilation groove 10 is located at one end close to the first actuator 4. Through the ventilation groove 10 provided on the side of the valve core guide sleeve 2, the space inside the valve core guide sleeve 2 and away from the valve core body 3 no longer forms a closed air chamber, so there is no need to consider the air pressure of the closed air chamber on the valve core body 3 during the upward movement and the vacuum suction force during the downward movement.
