Description
Technical Field
[0001] The utility model relates to the technical field of steam, in particular to a steam faucet structure. Background Art
[0002] A steam faucet is a component in a steam boiler or a steam generator. Its function is to control the output of steam. The steam faucet controls the steam flow generated by the boiler by adjusting the opening degree of a valve, so as to meet different production or living needs. The common steam faucet is opened by rotation. By making the transmission pin threadedly connected to the knob cooperate with the annular groove at the end of the valve stem, the valve stem is driven to displace. The threaded fit requires turning several circles to complete the opening and closing, and the operation is relatively cumbersome, and the opening and closing efficiency is low.

[0022] As shown in the appended Figure 1 and appended Figure 2 figures, the steam faucet structure of the present utility model includes a hollow valve body 1. An inlet steam cavity 11, a steam passage cavity 12 and a control cavity 13 that are sequentially communicated are formed inside the valve body 1. The inlet steam cavity 11, the steam passage cavity 12 and the control cavity 13 are on the same straight line. The diameter of the steam passage cavity 12 is smaller than the diameters of the inlet steam cavity 11 and the control cavity 13 respectively. The valve body 1 also has a steam outlet 14 communicated with the steam passage cavity 12. The steam outlet 14 is connected with a steam outlet pipe 2. A steam nozzle 3 is installed at the end of the steam outlet pipe 2. Steam enters the steam passage cavity 12 from the inlet steam cavity 11, and then sprays out from the steam outlet 14 along the steam outlet pipe 2 through the steam nozzle 3.
[0023] An inlet steam joint 4 is installed at one end of the inlet steam chamber 11 away from the steam passage chamber 12. A plug 5 is provided in the inlet steam chamber 11 for blocking the connection between the inlet steam chamber 11 and the steam passage chamber 12. One end of the plug 5 is formed with a connecting rod 51 extending towards the steam passage chamber 12. A control block 7 and a first return spring 6 are installed in the control chamber 13. The control block 7 is slidably connected to the control chamber 13. One end of the control block 7 extends into the steam passage chamber 12 and is connected to the connecting rod 51. The other end of the control block 7 is formed with a driving surface 73. The first return spring 6 applies a force to the control block 7 away from the steam passage chamber 12 to make the control block 7 pull the plug 5 close to the steam passage chamber 12. A second return spring 30 is installed in the inlet steam chamber 11 and abuts against the plug 5 to further provide a force for the plug 5 to seal the inlet of the steam passage chamber 12. The connecting rod 51 and the control block 7 are connected by threads.
[0024] The valve body 1 is connected with a driving member 8. The driving member 8 includes a contact rod 81 in contact with the driving surface 73 and a pressing rod 82 extending to the outside of the valve body 1. When an external force acts on the pressing rod 82, as shown in the appendix Figure 3 shown, the contact rod 81 slides along the driving surface 73 and pushes the control block 7 towards the inlet steam chamber, causing the plug 5 to leave the steam passage chamber 12, so that steam flows from the inlet steam chamber 11 into the steam passage chamber.
[0025] A control seat 9 is installed in the control chamber 13. A spherical cavity is formed in the control seat 9. A spherical support portion 83 is connected between the contact rod 81 and the pressing rod 82. The support portion 83 is embedded in the cavity to rotatably connect the driving member 8 with the control seat 9. The control seat 9 includes a vertical inner port and an outer port 91 communicating with the cavity. When no external force acts, the contact rod 81 contacts the lower end of the inner port, and the pressing rod 82 contacts the upper end of the outer port 91. When the pressing rod 82 is pressed by an external force, the contact rod 81 contacts the upper end of the inner port, and the pressing rod 82 contacts the lower end of the outer port 91. As shown in the appendix Figure 4 shown, the inner port and the outer port 91 play a limiting role to prevent the pressing rod 82 from shaking randomly, improve the movement accuracy of the driving member 8, and prevent the plug 5 from moving excessively or failing to fit with the inlet of the steam passage chamber 12, so as to avoid steam leakage.
[0026] The control block 7 includes a first section 71 with a diameter adapted to the steam passage chamber 12 and a second section 72 with a diameter adapted to the control chamber 13. A wedge block is formed on one side of the second section 72 away from the first section 71. The inclined surface of the wedge block is the driving surface 73. The end of the contact rod 81 is spherical to contact the driving surface 73 more smoothly and reduce wear.
[0027] A guide seat 10 is installed at one end of the control cavity 13 close to the steam passage cavity 12. The guide seat 10 has an opening through which the first section 71 of the control block 7 can pass, making the movement of the control block 7 smoother and more stable. A sealing ring 20 is installed between the opening and the first section 71 to improve the sealing performance and prevent steam from entering the control cavity 13 from the steam passage cavity 12 and affecting the use. The first return spring 6 is sleeved on the first section 71 of the control block 7 and abuts against the side surfaces of the guide seat 10 and the second section 72 respectively.
[0028] In the steam faucet structure of the present utility model, when not affected by external forces, the plug 5 and the control block 7 are respectively affected by spring forces, so that the plug 5 fits tightly with the entrance of the steam passage cavity 12, disconnecting the steam flow passage and preventing steam from entering the steam passage cavity 12 from the steam inlet cavity 11. When a downward force is applied to the pressing rod 82 of the driving member 8, the contact rod 81 pushes the control block 7 forward, causing the plug 5 to disengage from the steam passage cavity 12, and the steam inlet cavity 11 and the steam passage cavity 12 are connected, and steam can smoothly enter the outlet pipe 2. When the pressing rod 82 is not stressed, the plug 5 re-blocks the steam passage cavity 12 under the action of the spring, quickly resets, and quickly disconnects the steam passage. The operation is convenient, without the need for screwing actions, and the function of quickly switching the steam flow state is realized.
[0029] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
