Compared with the prior art, the utility model has the following beneficial effects:

1. No water leakage, the utility model has the double sealing effect of water pressure and thread, so that when the faucet is closed, the thread driving force and the water pressure jointly press the conical joint surface of the valve core and the valve body, so as to ensure that the faucet is worn out for a long time. No water leaks either.

2. Long service life, the use of cone-sealed valve, its joint surface is not afraid of wear, the more worn the joint surface is, the tighter the joint surface will be, and the service life will be extended.

3. The utility model is simple in structure and low cost. The valve core has a four-claw cone surface structure, which has the functions of reducing drag and passing water, supporting the valve core, shockproof and bearing water pressure. When the faucet is opened, the water flow is smooth, and the valve core is supported firmly Vibration, the water pressure presses the joint surface of the threaded driving pair through the valve core to ensure that the screw driving handle does not leak water. The faucet has only three components, including the elbow valve body, the valve core and the rotating handle, which makes the faucet simple in structure, reliable in function and low in cost. cost.

Detailed ways

Embodiment 1: This embodiment is described with reference to FIG. 1. This embodiment provides a threaded hydraulic double-sealed faucet, including an elbow valve body connected to the water pipe through an external thread, and a threaded connection with the elbow valve body and a conical surface. The sealed valve core 6 and the rotary handle 10 connected with the valve core 6 by four-edge screws; the elbow valve body includes a reducing joint 1 connected with the external thread of the water pipe and a main elbow connected with the internal thread of the reducing joint 1 Valve body 2; the middle of the inner cavity of the water inlet section of the main elbow valve body 2 is provided with a valve body sealing cone surface 4, which is used in conjunction with the valve core 6, and the main elbow valve body 2 is provided with a 90° faucet outlet. Section 7, the connecting section between the outlet section 7 of the faucet and the sealing cone surface 4 of the valve body is the throat 5, and the mounting section of the handle of the main elbow valve body 2 is provided with an internal thread hole 9 for controlling the movement of the valve core 6 The inner threaded hole 9 is arranged on the axis of the valve body sealing cone 4, the valve core 6 and the valve body sealing cone 4 form a cone sealing valve, and the valve core 6 and the inner threaded hole 9 form a threaded drive pair. Make the faucet have the double sealing effect of water pressure and thread.

In this embodiment, the reducing joint 1 considers the assembly of the valve core 6 and the connection of the main elbow valve body 2 and the water pipe with different diameters.

In this embodiment, because the diameter of the valve core 6 occupies the water flow space, the diameter of the main elbow valve body 2 is increased.

Embodiment 2: Referring to FIG. 1 , this embodiment will be described. This embodiment further defines Embodiment 1. In this embodiment, the valve core 6 includes the functions of conical sealing, supporting shockproof, bearing water pressure and diverting flow. The four-claw cone surface structure 3, the external thread rod 8 that drives the valve core 6 to move, and the four-edge thread structure 11 that fixes the rotary handle 10; the valve body sealing cone surface 4 of the main elbow valve body 2 and the four-claw cone surface Structure 3 forms a cone-sealed valve, and the internal threaded hole 9 of the main elbow valve body 2 cooperates with the externally threaded rod 8 to form a threaded drive pair, and the rotation of the threaded drive pair controls the opening and closing of the cone-sealed valve. Other components and connection methods are the same as in the first embodiment.

In this embodiment, the four claws 31 of the four-claw conical surface structure 3 play a supporting role and maintain the balance of the valve core 6 together with the threaded driving pair. When the valve is opened, the side clearance and the conical surface of the four claw 31 The water flow space is formed with the valve body sealing cone surface 4 of the main elbow valve body 2, and flows to the outlet section 7 of the faucet through the space between the valve core 6 and the throat 5.

Embodiment 3: This embodiment is described with reference to FIG. 2 . This embodiment further defines Embodiment 2.
