Description

Adjustable multichannel valve

Technical Field

The invention relates to a multi-channel valve, in particular to an adjustable multi-channel valve.

Background

Multi-channel valves are widely used. At present, the valve port of a valve core of the hydraulic steering priority valve adopts a non-full-circumference opening, namely a throttling groove structure and a full-circumference opening form under a large opening, and the structure has the valve port area gradient mutation, so that the problems of steering hydraulic impact, system vibration, noise, system power consumption and the like are easily caused, the motion damping in the valve core reversing process is only ensured by arranging a single damping hole form, the asymmetry of the bidirectional motion of the valve core cannot be completely matched, in addition, the existing hydraulic steering priority valve only considers one working form of static signal type or dynamic signal type, the problem of easy modification of the structure between the two is not considered, and the universality of the element is reduced.

In addition, as the number of channels increases, the structure tends to be more complex, and the control of the overall structure can be realized only by the linkage structure.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Examples:

an adjustable multi-channel valve as shown in fig. 1 to 4 comprises a valve body 1. The valve body 1 is composed of a mixing valve body 11 and one or more intake passage valve bodies 12. The mixing valve 11 has an output port 111 and a mixing chamber 112. The inlet passage valve body 12 is divided into a fitting pipe 123, a plug body 125, an elastic member 127, a rotary base 122, and an inlet pipe 124. The fitting pipe 123 has a feed end 121 at one end thereof. The plug 125 is movably sleeved in the matching pipe 123, and the rotary base 122 is sleeved on the other end of the matching pipe 123. The elastic member 127 is provided between the plug body 125 and the rotary base 122. One end of the liquid inlet pipe 124 is communicated with the middle part of the matching pipe 123, the other end is communicated with the mixing chamber 112, and a communication port 128 is arranged at the communication position of the liquid inlet pipe 124 and the mixing chamber 112. A check valve 129 is provided adjacent to the communication port 128.

In order to avoid the disconnection from the whole structure, a limiting slope 126 is also provided in the above-mentioned mating pipe 123. The inner diameter of the limiting slope 126 is smaller than the outer diameter of the plug 125, and the limiting slope 126 can effectively limit the movable range of the plug 125.

In order to increase the tightness, the annular edge of the limiting slope 125 is matched with the front annular edge of the plug 125.

To reduce the material of the rotating base 122, the material of the plug 125 is reduced, and at the same time, the compression space of the elastic member 127 is increased, reducing the resilience thereof. An upper accommodating cavity is formed in the plug 125, and the elastic member 127 is partially disposed in the upper accommodating cavity; the rotary base 122 has a lower accommodating chamber inside, and the elastic member 127 is partially disposed in the lower accommodating chamber.

As a preferred aspect of the present invention: the rotary base 122 is screwed with the fitting pipe 123, the elastic force of the elastic member 127 is adjusted by rotating the rotary base 122 with the fitting pipe 123, and the tightness of the elastic member 127 in the rotary base 122 is adjusted by adjusting the fitting depth of the rotary base 122 and the fitting pipe 123, so that the actual elastic force of the elastic member 127 can be adjusted.

In order to limit the rotary bottom piece (122) to carry out rotary adjustment, the bottom of the rotary bottom piece 122 is also provided with a fixed collar 13 in a matching way. The fixing collar 13 is composed of a fixing collar seat 131 and an extending fixing post 132. The rotary base 122 is provided with a first slot 1221 that mates with the extension fixing post 132. The above-mentioned mating pipe 123 is further provided with a second clamping groove 1231 matched with the extending fixing column 132, in order to avoid that the rotating base 122 is subjected to the reaction force of the elastic member 127 during the long-term use, the rotating base 122 rotates, so that the elastic force is weakened, and after the fixing collar 13 is clamped into the first clamping groove 1221 and the second clamping groove 1231, the rotating base 122 and the mating pipe 123 are stably mated, so that when the fixing collar 13 is not separated from the second clamping groove 1231, the rotating base 122 cannot be rotated and adjusted.

In order to further improve the stability of the fixing collar 13 and the mating tube 123, the extending fixing post 132 and the second clamping groove 1231 are provided with a plurality of clamping grooves, and the number of the extending fixing posts 132 may be equal to or greater than the number of the first clamping grooves 1221 and the second clamping grooves 1231.

As a further preferred aspect of the present invention: the length of the plug 125 is longer than the length of the sum of the inner diameter of the liquid inlet pipe 124 and the distance between the liquid inlet pipe 124 and the limiting slope 126, when the plug 125 contacts with the limiting slope 126, the side of the plug 125 contacting with the liquid inlet pipe 124 can completely cover the inlet end of the liquid inlet pipe 124, so as to avoid the liquid inlet pipe 124 flowing back into the movable section of the elastic member 127, and besides avoiding flowing back, the elastic force of the elastic member 127 floats, resulting in instability.
