Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a front-type valve for regulating flow. Background Art

[0002] Valves are common mechanical structures, such as faucets and valves at gas stove locations. Taking the valve in the faucet application scenario as an example, the valve needs to take on tasks such as opening and closing the faucet and regulating the flow of water. Frequent twisting is particularly likely to cause its simple structure to wear out and then quickly become scrapped, which will obviously bring inconvenience to users. If the existing faucet valve only performs one task, such as only making the existing valve responsible for opening and closing the faucet, while the flow regulation is completed by other structures, the wear rate of the existing valves and other structures can be effectively slowed down through task allocation. Based on this situation, how to realize the separate execution of opening and closing the faucet and regulating the flow, while slowing down the wear rate of existing valves and related structures, is becoming an increasingly urgent problem that relevant technical personnel need to solve.

[0022] Furthermore, a screw rod 3 is rotatably arranged at the center position of the valve sleeve 10, the valve core is threadedly connected to the screw rod 3, a limit plate 2 is arranged at a position corresponding to the screw rod 3 and the outer upper plate 9, the limit plate 2 is slidably connected to the outer upper plate 9, a rotating wheel 1 is fixedly arranged on the upper part of the screw rod 3, an inner chamber 14 is arranged inside the connecting seat 4, a fixed seat 5 is fixedly arranged at a position corresponding to the inner chamber 14 and the screw rod 3, and the lower part of the screw 3 is rotatably connected to the fixed seat 5.

[0023] Furthermore, the slide rails 11 are symmetrically arranged inside the valve sleeve 10 , and the sliders 23 are symmetrically fixedly arranged on both sides of the inner upper plate 16 , and the sliders 23 are slidably connected to the slide rails 11 .

[0024] Furthermore, a slide groove 8 is provided on the inner side of the outer lower plate 12 , a clamping block 6 is slidably provided inside the slide groove 8 , and clamping holes 24 are provided on the outer sides of the upper seat 22 , the middle seat 21 , and the lower seat 20 , and the clamping holes 24 correspond to the positions of the clamping blocks 6 .

[0025] Furthermore, the number of the card blocks 6 is 4 groups, and the 4 groups of card blocks 6 are equidistantly arranged in a ring shape.

[0026] Furthermore, the end of the block 6 close to the hole 24 is hemispherical, and the end of the block 6 away from the hole 24 is horizontally provided with a transverse groove, an annular spring 7 is provided inside the transverse groove, and the annular spring 7 fits in the transverse groove position of the block 6.

[0027] The working principle of a front-mounted valve for regulating flow of the utility model is as follows: the valve is installed between the existing valve of the faucet and the pipeline by connecting the inlet 13 and the outlet 15 of the seat 4. The valve is in a no-flow state by default. At this time, the clamping block 6 is clamped with the clamping hole 24 at the position of the lower seat 20, and the inner lower plate 19 is located in the middle position between the inlet 13 and the outlet 15 and separates the two. Even if the user opens the existing valve, water will not flow out of the faucet position. The wheel 1 is turned, and the wheel 1 drives the screw 3 to rotate. Combined with the sliding limit of the slide 23 by the slide rail 11, the valve core moves downward stably and vertically. When the clamping block 6 is clamped with the clamping hole 24 at the position of the middle seat 21, the inlet 1 3-lower through hole 18-outlet 15 are connected, and the existing valve is opened to obtain water flowing out at a small flow rate at the faucet position. The wheel 1 is continued to be turned until the block 6 is engaged with the hole 24 at the position of the upper seat 22, and the inlet 13-upper through hole 17 and the lower through hole 18-outlet 15 are connected. The existing valve is opened to obtain water flowing out at a large flow rate at the faucet position. The expansion of the annular spring 7 allows the valve core to move up and down smoothly, and the contraction of the annular spring 7 allows the block 6 to be engaged with the hole 24 to keep the valve core stable. In this way, the opening, closing and flow regulation of the faucet are respectively implemented, and at the same time, the wear speed of the existing valve and the valve is effectively slowed down.

[0028] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
