Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
The embodiment discloses a water inlet joint for a gas water heater, and as shown in fig. 1-5, the water inlet joint comprises a joint body 10, a flow blocking member 20, a fixing member 30 and an adjusting device 40. Wherein, the joint body 10 is a cylindrical structure having a flow passage therein, and a sidewall of the joint body 10 has a communication hole 101 communicating with the flow passage. The flow blocking member 20 is fitted to the communication hole 101. The fixing member 30 is coupled to the connector body 10, and the flow blocking member 20 is slidable between a first position and a second position with respect to the fixing member 30 by the hydraulic pressure. Wherein at least a portion of the baffle 20 extends into the interior of the fitting body 10 when the baffle 20 is in the first position. When the flow blocking member 20 is in the second position, an end of the flow blocking member 20 close to the joint body 10 is located in the communication hole 101.
Wherein, when the flow blocking member 20 is in the second position and the water pressure exceeds the preset value, the flow blocking member 20 acts on the adjusting means 40, so that the adjusting means 40 acts on the flow passage to partially block or completely block the flow passage.
In the present embodiment, when the water pressure is not high, the flow blocking member 20 is in the first position, at least a part of the flow blocking member 20 is located inside the joint body 10, and the flow blocking member 20 can function as a flow blocking member to restrict the water flow; when the water pressure is higher and higher, the flow blocking member 20 moves upward relative to the fixing member 30, the water flow rate is higher and higher, when the flow blocking member 20 is at the second position, the flow blocking member 20 moves out of the flow passage inside the joint body 10, the flow blocking member 20 does not play any flow blocking role, and the water flow rate is maximum; when water pressure exceeds the preset value, the flow blocking piece 20 acts on the adjusting device 40, and according to the size of the water pressure, the adjusting device 40 can block or completely block the flow channel, so that the water flow used for entering the gas water heater can be controlled or limited, and the expansion crack of the water inlet pipe can be prevented when the water pressure is too large. The structure is simple, the integral structure of the gas water heater is simplified, and the cost is reduced.
As shown in fig. 1 and 3-5, the fixing member 30 is provided with a blocking member 50, and the blocking member 50 can be switched between an initial state and a retracted state by an external force. When the water pressure does not exceed the preset value, the blocking member 50 is in an initial state, and the blocking member 50 extends out of the fixing member 30. When the water pressure exceeds a preset value, the blocking member 50 is in a retracted state, and at least a portion of the blocking member 50 is located inside the fixing member 30.
Wherein, when the flow blocking member 20 is in the second position as the water pressure increases, if the water pressure does not exceed the preset value, the blocking member 50 can block a portion of the regulating device 40 from acting (moving) and block the flow passage; when the water pressure exceeds a preset value, corresponding structures in the regulating device 40 apply an external force to the blocking member 50 to press the blocking member 50 and move along the blocking member 50. Under the action of the blocking member 50, the water flow is stable within a certain water pressure range, so that the water flow stabilizing device plays a role in stabilizing pressure and has a strong function of resisting water pressure fluctuation.
In an alternative embodiment, the outer wall surface of the blocking member 50 for receiving the external force is a slope, and the included angle between the slope and the central axis of the joint body 10 is an acute angle.
Here, with respect to the inclined direction of the slope, it can be understood that the outer wall surface of the blocking member 50 is gradually distant from the fixing member 30 in the flowing direction of the water. The outer wall surface of the blocking member 50, which bears the external force, is set to be an inclined surface, so that on one hand, the stability of the movement of the corresponding part in the adjusting device 40 along the blocking member 50 can be improved; on the other hand, the corresponding portion of the adjustment device 40 moves along the slope with a larger stroke than the flat surface, so that a larger adjustment range can be achieved in a smaller space.
As will be understood by referring to fig. 1 and 3 to 5, an end of the flow blocking member 20 remote from the joint body 10 is connected to the fixed member 30, and the adjusting device 40 includes a first sliding member 401, an elastic member 402, and an adjusting member, the first sliding member 401 being provided on the fixed member 30 and being slidable with respect to the fixed member 30. The elastic member 402 is fitted over the outside of the fixed member 30 and is positioned between the first sliding member 401 and the flow blocking member 20. When the flow blocking member 20 is in the first position, the elastic member 402 is in a natural state, and the first sliding member 401 is in the initial position. When the flow blocking member 20 is at the second position and between the first position and the second position, and the water pressure does not exceed the preset value, the elastic member 402 is compressed, and the first sliding member 401 is at the initial position.
When the water pressure exceeds a preset value, the elastic member 402 has a maximum compression amount, and the first slider 401 slides relative to the fixed member 30 and acts on the regulating member so that the regulating member partially blocks or completely blocks the flow passage.
When the water pressure is not high, the flow blocking member 20 is in the first position, at least a part of the flow blocking member 20 is located inside the joint body 10, the flow blocking member 20 can act as a flow blocking member to limit the water flow, the elastic member 402 is in a natural state, and the first sliding member 401 is in an initial position (as shown in fig. 3); when the water pressure is higher and higher, the flow blocking member 20 moves upward relative to the fixed member 30, the water flow rate is higher and higher, the elastic member 402 is compressed, when the flow blocking member 20 is in the second position, the flow blocking member 20 moves out of the flow passage inside the joint body 10, the flow blocking member 20 does not have any flow blocking function, the water flow rate reaches the maximum, the elastic member 402 reaches the maximum compression amount, if the water pressure does not exceed the preset value, the blocking member 50 blocks the first sliding member 401, the first sliding member 401 is still in the initial position (as shown in fig. 4), and the water flow rate is stable within a certain water pressure range; when the water pressure exceeds a preset value, the first slider 401 acts on the blocking member 50 and moves along the blocking member 50 and acts on the regulating member (shown in fig. 5) which can block or completely block the flow passage according to the magnitude of the water pressure. It should be noted that when the water pressure is reduced or absent, the components in the water inlet joint are reset under the action of the gravity of the flow blocking member 20 and the first sliding member 401 by the thrust of the elastic member 402.
Specifically, in the present embodiment, the elastic member 402 is a spring.
As shown in fig. 1 and 3 to 4, when the first slider 401 is in the initial position, the end of the blocking member 50 abuts against the first slider 401.
Because the movement of the first sliding member 401 drives the movement of the adjusting member, and the movement of the adjusting member partially blocks or completely blocks the flow channel, if there is a gap between the end of the blocking member 50 and the first sliding member 401, when the flow blocking member 20 is at the second position and the water pressure is close to the preset value, the first sliding member 401 may move, and because there is no function of the blocking member 50, the first sliding member 401 drives the adjusting member to move, so as to block the flow channel in advance. Therefore, the adoption of the structure is beneficial to avoiding unnecessary blockage of the flow channel as much as possible.
In an alternative embodiment, as shown in fig. 1-5, the adjustment member includes a second slide 403, a transmission assembly, and an adjustment assembly. The first slide 401 is connected to the second slide 403 by a first connecting rod 60, and the transmission assembly is drivingly connected between the second slide 403 and the adjustment assembly. Wherein the transmission assembly is used for converting the linear motion of the second sliding member 403 into a rotary motion.
When the first sliding member 401 moves, the second sliding member 403 also moves under the action of the first connecting rod 60, and at this time, the adjusting assembly rotates under the action of the transmission assembly, so that the adjusting assembly acts on the flow passage to partially block or completely block the flow passage.
In this embodiment, the adjustment assembly achieves partial or full blockage of the flow passage by rotation relative to the fitting body 10. In an alternative embodiment, the adjustment assembly may also be achieved by linear movement relative to the fitting body 10, e.g. by extending the adjustment assembly into or out of the flow passage.
In an alternative embodiment, the transmission assembly comprises a rack 404 and a gear 405, which are engaged with each other, the rack 404 is connected to the second slide 403, and the gear 405 is used for driving the adjustment assembly to rotate synchronously.
The second sliding member 403 moves to drive the rack 404 to move, and the rack 404 moves to drive the gear 405 to rotate, so as to drive the adjusting component to rotate synchronously. The gear 405 and the rack 404 are used as transmission components, the structure is simple, and the conversion from linear motion to rotary motion can be reliably realized.
As shown in fig. 1 to 5, the rack 404 is connected to the middle of the second slider 403 by the second connecting rod 70. In other alternative embodiments, the rack 404 may be directly connected to the end of the second slide 403.
When the rack 404 is connected to the middle of the second sliding member 403, the rack 404 and the second sliding member 403 may be arranged side by side, which is beneficial to increase the overall rigidity of the adjusting member and occupies less space compared to the structure connected to the end of the second sliding member 403.
As shown in fig. 1 and fig. 3 to 5, the adjusting assembly includes a rotating shaft 406 and an adjusting member connected to the rotating shaft 406, the adjusting member is located inside the connector body 10, and the gear 405 is sleeved outside the rotating shaft 406. The adjusting part comprises a ball valve 407, and the range of the rotation angle of the ball valve 407 is 0-90 degrees.
Wherein, when the ball valve 407 rotates 90 degrees, the ball valve 407 will block the flow channel completely, so as to block the inlet water completely, so that the water flow does not enter the inside of the gas water heater.
In an alternative embodiment, the adjusting member may be provided to include a fixed disk provided with a first through hole for communicating with the flow passage and a rotating disk. The rotating disc is connected to the rotating shaft 406, a second through hole used for being communicated with the first through hole is formed in the rotating disc, and the rotating disc is attached to the fixed disc so as to open or close the first through hole. Wherein the regulating member completely blocks the flow passage when the first through-hole is completely covered by a portion of the rotary disk where the second through-hole is not provided.
As shown in fig. 1-5, the second slide 403 is connected to the fixed member 30 by a connecting sleeve 80. Wherein, the connection between the fixed member 30 and the second sliding member 403 is facilitated by the connecting sleeve 80, and the connection is reliable.
