Therefore, the utility model provides a transfer and flow air-vent valve has solved the relatively poor problem of operation in-process stability.

In order to achieve the purpose, the utility model is realized by the following technical proposal:

a flow-regulating pressure-regulating valve comprises a hollow valve body with openings at two ends, a cylindrical flow guide body with an opening at one end is arranged at the center of the valve body, a sleeve capable of sliding along the flow guide body is hermetically connected in the flow guide body, a flow guide pipe is coaxially arranged on the sleeve at the opening end of the flow guide body, a plurality of waist round holes axially arranged along the flow guide pipe are uniformly arranged on the circumferential side surface of the flow guide pipe, a valve seat is arranged on the valve body at one side where the flow guide pipe is arranged, transmission shafts radially distributed along the flow guide body are hermetically arranged on the flow guide body, a crank connecting rod mechanism is arranged on the transmission shaft in the flow guide body, the output end of the crank connecting rod mechanism is connected on a sliding block, the sliding block is fixedly connected with the flow guide pipe and the sleeve, when the crank connecting rod mechanism moves, the waist round hole extends out of the valve seat completely, and the sleeve is abutted to the valve seat.

Preferably, the slider has a ring-shaped fixed ring and a plurality of connecting pieces extending to the center of the fixed ring, and the crank link mechanism is connected to the connecting piece at the center of the fixed ring.

Preferably, the installation face of disk seat and valve body is the ladder face, the sealing washer has been inlayed on the installation face of disk seat and valve body, works as when sleeve and disk seat looks butt, the sleeve is inlayed and is in on the ladder face and with the sealing washer is inconsistent.

By adopting the technical scheme, the beneficial effects of the utility model are that: the utility model discloses a structure of evenly circling cloth waist round hole on slidable honeycomb duct, the honeycomb duct, when the regulation, through the open interval of changing waist round hole change fluidic flow and pressure, this kind of structure fluidic flow and pressure when adjusting compare in traditional structure more even, especially when the valve is opened and close, can keep the interior fluidic stability of valve body and pipeline, reduce the production of swirl, water hammer, protected the life-span of pipeline and valve.

Detailed Description

The following detailed description will be given with reference to specific embodiments, so as to solve the technical problems by applying technical means, and to fully understand and implement the technical effects of the present invention.

Examples

Referring to fig. 1 and 2, a flow-regulating pressure-regulating valve includes a hollow valve body 1 with two open ends, a cylindrical flow guide body 2 with one open end is disposed at the center of the valve body 1, a sleeve 3 capable of sliding along the flow guide body 2 is hermetically connected in the flow guide body 2, a flow guide pipe 4 is coaxially mounted on the sleeve 3 at one open end of the flow guide body 2, a plurality of waist-shaped holes 41 axially disposed along the flow guide pipe 4 are uniformly formed on the circumferential side surface of the flow guide pipe 4, a valve seat 5 is disposed on the valve body at one side where the flow guide pipe 4 is mounted, a transmission shaft 6 radially disposed along the flow guide body is hermetically mounted on the flow guide body 2, a crank-link mechanism 7 is mounted on the transmission shaft 6 disposed in the flow guide body 2, the output end of the crank-link mechanism 7 is connected to a slide block 8, the slide block 8 and, The sleeve 3 is fixedly connected, when the crank link mechanism 7 moves to the limit in the direction out of the guide fluid 2, the waist circular hole 41 extends out of the valve seat 5 completely, and the sleeve 3 is abutted to the valve seat 5.

In this embodiment, the slider 8 has an annular fixed ring and a plurality of connection pieces 81 extending toward the center of the fixed ring, and the crank link mechanism 7 is connected to the connection pieces 81 at the center of the fixed ring. According to the structure, the connection of the sliding block 8, the sleeve 3 and the flow guide pipe 4 is more compact, the connection points are uniformly distributed, when the transmission shaft 6 is used for transmission, the transmission direction of the crank connecting rod mechanism 7 is located at the center of the whole structure, the structure is more stable when the sleeve 3 is pushed to slide, and the problem that the sleeve 3 is unsmooth in sliding due to uneven stress when the sleeve 3 slides is avoided.
