Description

Improved structure of gate valve

This creation relates to an improved structure of a gate valve, especially an improved structure of a gate valve that can truly achieve the effect of preventing leakage, and can make the knob rotate more smoothly, thereby preventing the generation of noise.

Press; the gate valve is a kind of valve that uses a circular water stop piece to open and close, and rotates with the knob to open, close and adjust the fluid channel. As shown in FIG. 1, the conventional gate valve is provided with a main body 1, and the main body 1 is provided with a water outlet 11 and a water inlet 12, and an accommodation space which communicates with the water outlet 11 and the water inlet 12 and is in a vertical direction. An opening section 13 extends upward from the accommodating space, and a screw rod 14 is arranged inside the main body 1. After the screw rod 14 is penetrated with elements such as a tightening ring 15 and a sleeve 16, a circular water-stop sheet is locked at the bottom end of the screw rod 14. 17. The top is locked with a knob 18. By turning the knob 18, the water stopper 17 is rotated around the axis, and the rotation angle is between 0° and 90°. When it is rotated to 90°, the water stopper 17 is fully open. , changing the deflection angle of the water stop piece 17, the flow of the medium can be controlled and completely closed. The gate valve has the advantages of fast switching speed, less openness, less blockage, and good control ability. It is suitable for throttling and switching, especially for large flow control and regulation.

The conventional gate valve and the knob 18 only rely on the screw 14 and the tightening ring 15 and other components to form the tightening state, and lack buffering effect. Therefore, when the knob 18 is tightened, only the external screw 14 is tightened, which not only causes the lack of smooth rotation, but also causes noise due to the unsmoothness. In view of this, the applicant, through continuous research and experimentation, came to design an improved structure of the gate valve, so as to achieve the anti-leakage effect, and the knob can be rotated more smoothly, thereby preventing the generation of noise.

The main purpose of this creation is to provide an improved structure of the gate valve, so that the gate valve can indeed achieve the anti-leakage effect during use, and the knob can be rotated more smoothly, thereby preventing the generation of noise.

The improved structure of the aforementioned gate valve is provided with a main body, the main body is provided with an outlet and a water inlet, and an accommodating space communicated with the outlet and the water inlet and is in a vertical direction, and an opening section extends upward from the accommodating space, and is located in the accommodating space. A screw through a tightening ring, a sleeve, etc. is placed in the opening section, and a water-stop sheet is fixed at the bottom end of the screw, and a knob is arranged on the top edge of the screw. It is parallel to the water outlet and the water inlet to form a channel to open, or to block the water inlet and the water outlet by the water stop sheet to close the water outlet. Wherein, the screw is provided with a surrounding protruding wall at an appropriate position, and a surrounding inserting groove is arranged above the protruding wall for embedding a water-stop O-ring, so as to form a certain anti-leakage effect, and make the knob in the It rotates more smoothly, thus preventing the generation of noise.

In the improved structure of the aforementioned gate valve, the screw rod is placed in the opening section of the main body, and the upper part of the screw rod is set as a penetration section for passing through a tightening ring and a sleeve, so that the top end is locked to the knob; It is a thread segment for locking on the water stop.

In the improved structure of the aforementioned gate valve, the protruding wall of the screw rod is arranged between the penetration section and the screw thread section.

Please also refer to FIG. 2 and FIG. 3 , which are a three-dimensional view and a three-dimensional exploded view of this creation. As shown in the figure, the present creation system is provided with a main body 2, the main body 2 is provided with a water outlet 21 and a water inlet 22, and a accommodating space communicated with the water outlet 21 and the water inlet 22, and is in a vertical direction. An opening section 23 extends upward from the space, and an upper cover 24 is locked at the top edge of the opening section 23 .

The main body 2 is provided with an annular water-stop sheet 25, and a screw 26 whose bottom end is fixed on the water-stop sheet 25. The screw 26 is placed in the opening section 23 of the main body, and the upper part thereof is set to pass through. Section 261, the lower part is set as a screw thread section 262 for locking on the water stop piece 25. After a washer 27 and an upper cover 24 are respectively pierced through the piercing section 261, a tightening ring 28 and a sleeve 29 are pierced so that the top ends are locked to a knob 30, and a nut 31 and a C Type buckle 32 is positioned up and down. Through the rotation of the knob 30, the hole of the water stopper 25 is parallel to the water outlet 21 and the water inlet 22 to form a channel to open, or the water stopper 25 blocks the water outlet 21 and the water inlet 22 to form a structure. closure.

The screw 26 of the present invention is fastened between the penetration section 261 and the screw thread section 262, and is provided with a surrounding protrusion 263, and a surrounding insert groove 264 is arranged above the protrusion for the insert groove 264. A water-stop O-ring 33 is embedded to form a sure anti-leakage effect, and make the knob 30 rotate more smoothly, thereby preventing the generation of noise.

Please refer to Figure 4, which is a cross-sectional view of this creation. As shown in the figure, the screw 26 of the present invention is placed in the opening section 23 of the main body, the upper part is set as a penetration section 261, and the lower part is set as a screw thread section 262 for locking on the water stop piece 25. After a washer 27 and an upper cover 24 are respectively pierced through the piercing section 261 , a tightening ring 28 and a sleeve 29 are pierced so that the top end is locked to a knob 30 . When the knob 30 is rotated, the water-stop sheet 17 can rotate around the axis with the screw 26, and the rotation angle is between 0° and 90°. When it rotates to 90°, the water-stop sheet 17 is fully open. The deflection angle of the water stop piece 17 can control the flow of the medium and completely close it to achieve throttling and switching. Among them, because a water-stop O-ring 33 is arranged between the penetration section 261 of the screw 26 and the screw thread section 262, the water-stop O-ring 33 is supported on the tightening ring 28. When the knob 30 rotates the screw 26 , the water-stop O-ring 33 can be used to form a buffering effect, in addition to achieving a certain anti-leakage effect, the knob 30 can be rotated more smoothly, thereby preventing the conventional gate valve from being tightened only by the screw resulting in the absence of noise.

The foregoing examples are only to illustrate the preferred implementations of the present creation, rather than limiting the scope of the present creation. All modifications and changes are made without losing the essence of the present creation, nor deviating from the spirit of the present creation.

To sum up, in this creation, a screw with an embedded groove and a water-stop O-ring embedded in the embedded groove constitute an improved structure of the gate valve, so that the gate valve can indeed achieve the anti-leakage effect during use, and it is also The knob can be rotated more smoothly, thereby preventing the lack of noise generated when the conventional gate valve is rotated. It is a practical design, and it is a creation of novelty. I should file a patent application in accordance with the law, and I pray that the bureau will review it and grant the patent as soon as possible.
