Integrated aqueous medium one-way valve

Abstract

The invention discloses an integrated aqueous medium one-way valve, which comprises an integrated block substrate of which the inside is provided with a group of channels; a port of each channel is fixedly connected with a flange which is used to communicate with an external pipeline; at least one channel inside the substrate is provided with a mounting hole in which an aqueous medium one-way valve is arranged; and the aqueous medium one-way valve consists of an upper valve body, a spring, a sliding sleeve, a valve ball, a valve seat and a lower valve body, wherein the upper and lower valve bodies are closely matched, butted and fixed in the mounting hole; the lower valve body is provided with the valve seat which is provided with the valve ball in a floating way; the sliding sleeve seatson the valve ball, and slides in an inner hole of the upper valve body; the spring is supported between the upper part of the sliding sleeve and the wall of an end flange; and the middle section of the upper valve body is provided with a group of through holes communicated with the channels in the substrate. The integrated aqueous medium one-way valve can adopt an insertion type mounting structural form, so that a plurality of aqueous medium one-way valves are arranged in the integrated block, and required functions are realized through different combinations; and the invention provides the aqueous medium one-way valve which can be used for aqueous medium, particularly sewage medium, and realizes one-way flowing of liquid.

Description

technical field [0001] The invention relates to a hydraulic transmission mechanical device, in particular to an integrated water medium check valve. Background technique [0002] Existing hydraulic check valves generally adopt the structure of a cone valve. This type of check valve can well control the one-way flow of oil in an oil medium hydraulic system, but in water medium (especially in sewage medium) Among them, the edge of the valve seat and the sealing contact surface of the valve core are prone to wear due to the large force of the line contact, so that the check valve of this form will puncture and leak in a short time, and lose the one-way flow function of the liquid. This type of check valve has high processing precision requirements for the contact parts, resulting in high processing difficulty and high processing costs, and the parts interchangeability of the sealing parts is also relatively poor, so standardized production cannot be realized.

[0002] Existing hydraulic check valves generally adopt the structure of a cone valve. This type of check valve can well control the one-way flow of oil in an oil medium hydraulic system, but in water medium (especially in sewage medium) Among them, the edge of the valve seat and the sealing contact surface of the valve core are prone to wear due to the large force of the line contact, so that the check valve of this form will puncture and leak in a short time, and lose the one-way flow function of the liquid. This type of check valve has high processing precision requirements for the contact part, resulting in high processing difficulty and high processing cost, and the parts interchangeability of the sealing part is also relatively poor, so standardized production cannot be realized

[0003] In addition, if multi-path valve control is to be realized, many valves need to be used, and many connected pipelines will take up a lot of space. Not only the manufacturing cost is high, but also the amount of inspection and maintenance is also large.
