Abstract
The invention discloses a three-way check valve for an adsorption type drier. In the check valve, a left auxiliary valve body and a right auxiliary valve body are arranged at two sides of a main valve body respectively; a valve clack in the main valve body is formed by a left valve clack and a right valve clack which can move relative to each other; the left side of the left valve clack and the inner port of the left auxiliary valve body form a sealed pair, and the action of a first force application mechanism ensures that the left side of the left valve clack is normally closed at the inner port of the left auxiliary valve body; and the right side of the right valve clack and the inner port of the right auxiliary valve body form a sealed pair, and the action of a second force application mechanism ensures that the right side of the right valve clack is normally closed at the inner port of the right auxiliary valve body. In the three-way check valve, further improvement is carried out on the structure of the conventional three-way valve, the valve clack is designed to be of a split structure comprising the left valve clack and the right valve clack, and the left valve clack and the right valve clack are sealed at the inner port of the left auxiliary valve body and the inner port of the right auxiliary valve body respectively by the force application mechanisms, so that a common check valve at the air outlet can be saved, the three-way check valve has the function of the check valve while the requirement that two tanks of the adsorption drier alternately work and exhaust is met.
Description
Technical field
The present invention relates to a kind of parts of absorption drier, specifically relate to a kind of threeway check-valves that is used for absorption drier.
Background technology
Absorption drier combines the advantage of transformation absorption and alternating temperature absorption, absorption (work) under the high vapor partial pressure of normal temperature, under the low vapor partial pressure of higher temperature, resolve (regeneration), be the moisture content that adsorbent adsorbs in adsorption process, rely on the acting in conjunction of high-quality thermal diffusion of producing (dry air heating) again and two kinds of mechanism of low dividing potential drop and be able to thorough removing in regenerative process.Equipment is made generally in two jars of forms, under the control of cyclelog, and two jars of alternations, one jar of adsorption moisture, another jar resolved regeneration, continuously the work of circulation.Because the deficiency of valve member structure in the prior art, the outlet pipe of two tank tops connect comparatively complicated, on pipeline, need to install at least five air valves and satisfy two jars of alternately demands of exhaust, one comes the production cost height, installation and maintenance are also inconvenient, and two come parts to connect complexity, and performance is understable.This China invites the person applied for " triple valve that is used for absorption drier " (patent No.: patent 200920121418.2) on May 31st, 2009, with the structure of its advantages of simple, replaced and connected the discharge duct of two tank tops of absorption drier and at least five air valves on the pipeline in the prior art; The pressure fast moving of jar gas sealed left and right sides air inlet about valve plug spare in its structure relied on, can satisfy two jars of alternately demands of exhaust, but valve plug spare is the integral type parts, when all not having gas output for two jars, valve plug spare can not be about to the sealing of left and right sides air inlet certainly, and the place, gas outlet has gas backstreaming to influence its operate as normal in arriving jar easily.In order to prevent that the place, gas outlet from having gas backstreaming to arrive in the jar, in the prior art be to be provided with common check-valves at the place, gas outlet, make system cost increase like this, and reduced the stability of system.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical problem, and a kind of threeway check-valves that is used for absorption drier is provided
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of threeway check-valves that is used for absorption drier, comprise main valve body, the main valve body both sides are respectively equipped with left auxiliary valve body and right auxiliary valve body, flap in the main valve body forms sealing pair respectively with the inner port of left auxiliary valve body and right auxiliary valve body respectively, flap in the described main valve body is made of left flap that can relatively move and right flap, the inner port formation sealing pair of left surface and the left auxiliary valve body of left side flap, and the first force application mechanism effect makes the normally closed inner port place at left auxiliary valve body of left surface of left flap; The right flank of right flap and the inner port of right auxiliary valve body formation sealing pair, and the second force application mechanism effect makes the normally closed inner port place at right auxiliary valve body of right flank of right flap.When two jars of absorption drier did not all have gas output, left flap and right flap can relatively move under the force application mechanism effect respectively the inner port sealing of left auxiliary valve body and right auxiliary valve body; During two jars of alternate runs, gas pressure overcomes this force application mechanism makes sealing pair open, and the dry gas in two jars alternately enters into air accumulator.
As preferably, the middle part is provided with the triangular support that is used to support left and right sides flap in the described main valve body, the right-hand member cunning of wherein left flap valve rod fits in the centre bore of triangular support, and the left end cunning of left flap valve rod fits in the centre bore of the left flap triangular support in the left auxiliary valve body; The left end cunning of right flap valve rod fits in the centre bore of triangular support, and the right-hand member cunning of right flap valve rod fits in the centre bore of the right flap triangular support in the right auxiliary valve body.
As preferably, be provided with left flap back-moving spring between the left side of the right side of described left flap and triangular support, left flap back-moving spring constitutes described first force application mechanism; Be provided with right flap back-moving spring between the right side of the left side of described right flap and triangular support, right flap back-moving spring constitutes described second force application mechanism.
The present invention has done further improvement on the structure of original triple valve, flap design is become the branch body structure of left flap and right flap, utilize force application mechanism left and right sides flap to be sealed in the inner port place of left and right sides auxiliary valve body respectively, when satisfying two jar alternations of absorption drier exhaust demand, also had the function of check-valves.The present invention replaces original triple valve structure, can save the general check valve at the place, gas outlet, has simplified system architecture, has reduced equipment cost, has also improved the stability of system.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
