Abstract
The invention relates to a self-reliance exhaust balance valve which comprises a T-shaped valve body provided with three channels, wherein one of the channels is an exhaust channel, and the other two channels are output channels. The self-reliance exhaust balance valve is characterized in that a valve core is transversely arranged at the center of the inner chamber of the T-shaped valve body, the middle part of the valve core is a flange part the two sides of which are provided with matching surface matched with the inner chamber wall of the T-shaped valve body to form a valve gate; the two output channels of the T-shaped valve body are internally provided with a press cap respectively; and the two caps prop against the two transverse end faces of the valve core through pressure springs so as to fix the position of the valve core. The self-reliance exhaust balance valve has the advantages of novel structure, small size, light weight, high sensitivity, long service life and multiple functions, and can operate without control.
Description
Technical field
The present invention relates to a kind of self-powering type exhaust equilibrium valve.
Background technique
Equilibrium valve is a kind of valve of specific function, and the thing special way of valve own only is that function of use and place have any different.In some industry, because medium (all kinds of flowable materials) exists bigger pressure difference or difference in flow in the various piece of pipeline or container, for reducing or this difference of balance, between corresponding pipeline or container, install valve, in order to regulate the relative equilibrium of pressure at both sides, or reaching the balance of flow by the method for shunting, this valve just is equilibrium valve.Existing equilibrium valve volume is bigger and heavier, often needs manager works, and labor intensity is big, also can produce the valve flow regulating error.
Summary of the invention
In view of the deficiencies in the prior art, the object of the present invention is to provide a kind of self-powering type exhaust equilibrium valve of novel structure, the volume of this equilibrium valve is little, in light weight, need not personnel's control, and highly sensitive, the life-span is long.
Technological scheme of the present invention is: a kind of self-powering type exhaust equilibrium valve, comprise T-valve body with three passages, three passages are respectively an exhaust passage and two output channels, it is characterized in that: the lumen centers of described T-valve body has been horizontally set with spool, the middle part of described spool is a lip part, two sides of lip part are provided with the fitting surface that matches with T-valve intracoelomic cavity wall to form valve, be respectively equipped with pressure cap in two output channels of described T-valve body, two pressure caps withstand the position of two horizontal end faces of spool with fixed spool through stage clip respectively.
The fitting surface that described spool matches with the T-valve body is conical surface, plane or hemisphere face.
Described spool is made by resistant material.
Described fitting surface is provided with seal ring, and described seal ring is teflon or silica gel material.
Described pressure cap is the adjustable seamless cap that is used to finely tune rate-of flow, and described adjustable seamless cap has the outside thread that matches with the internal thread of output channel.
Compared with prior art, the present invention has the following advantages: the spool that (1) this equilibrium valve adopts resistant material to process, long service life; (2) this equilibrium valve adopts teflon or silica gel sealing ring, and sealability is reliable; (3) this equilibrium valve novel structure gets final product work by the pressure of self medium, and volume is little and in light weight, but multi-purpose valve; (4) adjustable seamless cap is located spool through stage clip, and balancing speed is fast, highly sensitive and need not personnel control; (5) can be widely used in industries such as oil, light textile and medicine, be specially adapted to the deep-sea aquaculture field.
Description of drawings
Fig. 1 is the organigram of the embodiment of the invention.
Embodiment
With reference to figure 1, a kind of self-powering type exhaust equilibrium valve, comprise T-valve body 1 with three passages, three passages are respectively an exhaust passage 11 and two output channels 12, it is characterized in that: the lumen centers of described T-valve body 1 has been horizontally set with spool 2, the middle part of described spool 2 is a lip part, two sides of lip part are provided with the fitting surface that matches with T-valve body 1 internal chamber wall, be respectively equipped with 3, two pressure caps 3 of pressure cap in two output channels 12 of described T-valve body 1 and withstand the position of two horizontal end faces of spool 2 through stage clip 4 respectively with fixed spool 2.
The fitting surface that above-mentioned spool 2 matches with T-valve body 1 is conical surface, plane or hemisphere face, and the spool 2 ventilation forms of this exhaust equilibrium valve can be diversified.
Above-mentioned spool 2 is made by resistant material, long service life.
Above-mentioned fitting surface is provided with seal ring 5, and above-mentioned seal ring 5 is teflon or silica gel material, and sealability is reliable.
Above-mentioned pressure cap 3 is for being used to finely tune the adjustable seamless cap of rate-of flow, and above-mentioned adjustable seamless cap has the outside thread that matches with the internal thread of output channel 12, and the user can regulate the position of pressure cap 3 according to actual needs.
This self-powering type exhaust equilibrium valve is to utilize differential pressure action to come the aperture of regulating valve, utilize the change in location of spool to remedy the variation of loine pressure, when working conditions change, can keep pressure reduction constant thereby make, its principle is in certain range of flow, the pressure reduction that can control controlled system effectively is constant, promptly when the pressure reduction of two pipelines that connect output channel increases, automatic displacement action by spool, guarantee the controlled system pressure balance, when pressure reduction reduces, spool automatically resets, and still keeps the constant pressure of two pipelines.
Working principle of the present invention is: when valve did not have pressure, because the effect of stage clip, spool mediated all the time, and the sectional area of its both sides output channel is equated; When valve working, two media that delivery outlet is exported simultaneously, flow to mixing duct from the exhaust passage, when the pressure of two delivery outlets changes, spool is subjected to the promotion of high voltage terminal pressure to the low voltage terminal displacement, strengthened the delivery outlet sectional area of high voltage terminal, reduced the delivery outlet sectional area of low voltage terminal, thereby accelerated the gas output of high voltage terminal, when pressure drops to when identical with low voltage terminal,, make spool travel because the pressure on both sides equates, reach new balance, spool is got back to the neutral position again; When this self-powering type exhaust equilibrium valve is used as two position three-way valve, need not extraneous control, need only a output medium at two delivery outlets, one of them is subjected to the effect of thrust and will closes automatically.
The present invention is specially adapted to the combined balance system of two media on the production technology.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to the present patent application claim change and modify, and all should belong to covering scope of the present invention.
