Problems solved by technology

Although the above-mentioned patent can realize the one-way throttling function, when throttling, it only changes the size of the flow area and has no pressure compensation function. When the load changes, the output flow changes greatly; and when the one-way function is realized, the oil also To flow through the throttling groove, the flow resistance is relatively large, so it is not suitable for use in low-pressure hydraulic systems

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Such as Figure 1 to Figure 2 Shown is the structural representation of the present invention,

[0017] The reference signs are: port A, port B, valve body 1, first flow hole 1a, second flow hole 1b, first flow groove 11, second flow groove 12, partition plate 13, valve Core 2, orifice 2a, spring 3, retaining ring 4, the direction of the arrow in the figure indicates the direction of fluid flow.

[0018] Such as Figure 1 to Figure 2 as shown,

[0019] A one-way throttle valve, including a valve body 1, a first flow groove 11 and a second flow groove 12 are arranged in the valve body 1, and a first flow groove 11 and a second flow groove 12 are arranged between the first flow groove 11 and the second flow groove 12 There is a partition 13, the outer wall of the valve body 1 is provided with a first flow hole 1a communicating with th...

Abstract

The invention discloses a one-way throttle valve which comprises a valve body. A first through-flow groove and a second through-flow groove are formed in the valve body. A partition plate is arrangedbetween the first through-flow groove and the second through-flow groove. A first through-flow hole communicating with the first through-flow groove is formed in the outer wall of the valve body. A second through-flow hole communicating with the second through-flow groove is further formed in the outer wall of the valve body. A valve element capable of axially moving is arranged in the valve body.A spring is arranged in the valve element in a sleeved manner. A throttle hole is formed in the valve element. When the valve element moves leftwards, the spring is compressed, the second through-flow groove is cut off by the valve element, and the opening degree of the first through-flow groove can be controlled. When the valve element moves rightwards, the first through-flow groove and the second through-flow groove are connected. The one-way throttle valve has the advantages that a one-way valve and a throttle valve are integrated, the structure is reasonable and compact, and flow resistance is small.

Description

technical field [0001] The invention relates to the technical field of throttle valve manufacturing, in particular to a one-way throttle valve. Background technique [0002] The function of the ordinary one-way valve is to make the hydraulic oil flow in one direction only, and it is not allowed to flow backwards. The function of the ordinary throttle valve is to control the flow of the fluid by changing the throttle section or length If the throttle valve and the check valve are connected in parallel, they can be combined into a one-way throttle valve, that is, the check valve can be opened in a specific direction without throttling effect, and the check valve cannot be opened in the direction opposite to the specific direction, only the throttle valve Outflow has a throttling effect. The current general one-way throttle valve is basically composed of two components, a valve sleeve with the function of a one-way valve and a valve core with a throttle hole. Larger, it is di...
