    • 专利摘要:
    Two gases are fed to a mixing valve having two outlets, and the proportions of the two gases, at each of the said outlets, is varied inversely in accordance with the position of a moveable portion of the mixing valve. If the back pressure at the two outlets is equal, and if the supply pressure of the two gases is equal, the proportioning of the two gases will be accurately determined by the adjustment of the valve. Thus, in an automatically controlled system requiring the presence of gases in time-variable proportions, proper proportioning can be achieved by the use of a mechanical valve, without the necessity of a gas testing analyzer and a feedback system for controlling an ordinary mixture proportioning valve.

    I
    This invention relates to mechanical engineering, in particular to pneumatic and hydraulic distribution systems.
    A mixing valve is known, containing a translational plate moving one relative to the other and a distribution plate mounted on it, with two inlet and four throttling channels hydraulically connected in pairs with inlet channels in the base, and two output channels in the plate and along each of them a communication channel which is hydraulically connected with it and which goes to a surface in contact with the base; the base throttling channels are made with rounded ends 1 J.
    However, the known valve has an insufficient adjustment accuracy, 20 due to the fact that with a slight relative movement of the plate and the base, the ratio of the liquids to be mixed changes significantly .25
    The purpose of the invention is to improve the accuracy of regulation.
    The goal is achieved by the fact that the cross sections of the four throttling channels of the base are made in the shape of a triangle, which in one-pair of these channels face each other vertices and in the other - bases.
    FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, longitudinal section; on .fig. 3 is a section A-A in FIG. 2; in fig. 4 - base without bronze plates, general appearance; on fkg. 5 - section bb of FIG. four; in fig. 6 - bronze lining, general view; in fig. 7 and 8 - channel slits in the plate and base.
    The valve contains a base and a distribution plate 2, while the bases have input channels 3 and 4 supplying mixed media (for example, oxygen and nitrogen), which are hydraulically connected to throttling channels 5-8, made in the form of facing each other and -1 mi triangle, gb :. The contacting surfaces of the base 1 and the plate 2 are fastened using a bonding material 9 on a thickness of 2 layers of elastic material 10 and plastic (for example, from a polytetra of fluoroethylene), and on the basis of a strip 12 of bronze bronze, and the channels 5-8 are made in this gasket 12, Plate 2 has a groove 13, which interacts with the ball 14, connected to the plate 13, which is adapted to the drive b. I. The plate 2 is pressed against the base with the help of the cover 17, in which the loaded balls 18 are mounted, while the cover 17 moves along the beam. Yugdim 19 In plastic, output channels 20 and 2 i dp of the output of media environments are made, communication channels 22 and 23, 1Spapan, work as follows. When the screw 16 is rotated, the pusher 15 with the help of the ball 14 moves the plate 2 attached to the base I of the ball 8, size. Den11№r in the key J7. Channels 3 and 4 of the basic I are supplied with clean cMeiBHBaei-ffljie media (for example, oxygen and nitrogen), which pass through the dropping channels 5–8 .and, mixing, pass through the weekend paths of channels 20 and 21 in Ipastine 2. So as channels 5-8 are made in the form of a triangle-shkov and the bases are turned to each other. And we have done so, then the media are mixed in an inversely proportional ratio, with 5 this can be very precise adjustment of the ratio of the mixed media. The presence on the contacting surfaces of the base 1 and plastish 2 of gaskets made of beryl bronze 12 and plastic 1 reduces frictional forces k, therefore, the drive power. invention mixing valve containing progressively displacing one relative to another, the base if installed on it distribution gshastina, at the base there are two input and four throttling channels, hydraulically connected in pairs with the input channels and the exit shch1-gx on the contact surface with the plate, and in the plate - two output channels and two outlets on the contact surface of the communication channel with the base, hydraulically removed from the outgoing channels and perpendicular to the throttle body channels, about tl and h ay Bj; and in order to increase the accuracy of regulation, four throttling channels are based on van and made in the form of triangles, with one pair of channels being vertically connected to each other, and the other with triangle bases.

    Claim
    A mixing valve containing progressively moving one relative to the other, a base AND a distribution plate mounted on it, at the base there are two inlet and four throttling channels, hydraulically connected in pairs with the inlet channels and exiting onto the surface in contact with the plate, and two output channels in the plate and When the screw 16 is rotated, the pusher 15, using the ball 14, moves the plate 2 pressed against the base I by balls 18, schennymi in the lid 17. The net miscible medium is supplied to the channels 3 and 4 of the base 1 (e.g., oxygen and nitrogen) that pass through the throttle channels 5-8 and mixed, are held in the output channels 20 and 21 in the plate

    2. Since the channels 5-8 are made in the form of triangles and obrazation channels, hydraulically connected to the output channels and perpendicular to the throttling channels, characterized in that, in order to improve the regulation accuracy, the four throttling channels of the base are made in the form of triangles, while one a pair of channels faces each other with vertices, and the other with the bases of the triangles.
