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 three-port check damper for absorption drier.
Background technology
Absorption drier combines the advantage of pressure-variable adsorption and Temp .-changing adsorption, 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 again (dry air heating) 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 tank forms, under the control of cyclelog, and two tank alternations, a tank adsorption moisture, another tank is resolved regeneration, the work of continuous circulation.Because the deficiency of valve member structure in the prior art, the outlet pipe of two tank tops connect comparatively complicated, need to install at least five air valves at pipeline and satisfy the demand that two tanks replace exhaust, one comes production cost high, 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; Valve plug spare in its structure relies on the pressure fast moving of left and right sides tank gas that left and right sides air inlet is sealed, can satisfy the demand that two tanks replace exhaust, but valve plug spare is the integral type parts, when two tanks all do not have gas output, 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 arrive easily affects its normal operation in the tank.In order to prevent that gas outlet place from having gas backstreaming to arrive in the tank, be to be provided with common check-valves at the place, gas outlet in the prior art, like this so that the system cost increase, and reduced Systems balanth.
Summary of the invention
The present invention solves the existing technical problem of above-mentioned prior art, and a kind of three-port check damper for absorption drier is provided
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of three-port check damper 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 respectively sealing pair 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 the left flap that can relatively move and right flap, the left surface of left flap and the inner port of left auxiliary valve body form sealing pair, and the first force application mechanism effect is so that the normally closed inner port place at left auxiliary valve body of the left surface of left flap; The right flank of right flap and the inner port of right auxiliary valve body form sealing pair, and the second force application mechanism effect is so that the normally closed inner port place at right auxiliary valve body of the right flank of right flap.When two tanks 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 tank alternate runs, gas pressure overcomes this force application mechanism so that sealing pair is opened, and the dry gas in two tanks alternately enters into air accumulator.
As preferably, the middle part is provided with for the triangular support that supports left and right sides flap in the described main valve body, the right-hand member cunning of its 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 consists of described the 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 consists of described the second force application mechanism.
The present invention has done further improvement in the structure of original triple valve, flap design is become the Split type structure of left flap and right flap, utilize force application mechanism left and right sides flap to be sealed in respectively the inner port place of left and right sides auxiliary valve body, when satisfying two tank 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 Systems balanth.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
