Abstract
The utility model relates to an improved disk type steam trap valve, which comprises a valve cap, a valve body, a valve core, a valve sheet and a casing. A steam inlet and a draining port are respectively arranged on two sides of the valve body; the casing is arranged above the valve body; the valve core fixed on the valve body is arranged in the casing; the valve sheet is arranged at the upper end of the valve core; the valve cap fixed on the valve core is arranged above the valve sheet; the valve core is respectively provided with a damping hole and a ventilation channel; the damping hole is communicated with a water drain port on the valve body through a valve body channel on the valve body; and symmetrical capillary slots passing through the circle center are formed on the lower end face of the valve sheet in the valve cap, which is positioned at the upper end face of the valve core. With the scheme, the area of the mirror surface of the valve sheet is reduced; the time for ejecting the valve sheet is prolonged; condensing water can be smoothly drained from the part between the capillary slots; and work steam generates secondary steam through the capillary grooves to prevent the work steam from escaping. Through the proof of by practice, the service life of the disk type steam trap valve is prolonged by over 9000 hours.
Description
Technical field
The utility model relates to a kind of drain valve, especially relates to a kind of modified model Shemostatic team trap.
Background technique
TD series drain valve in the prior art is made up of parts such as valve block, valve body, valve gap, plugs, and it is simple in structure, and valve block smooth decreasing when drain valve is closed is untimely but this drain valve is closed, and steam leakage is very serious.PIN series drain valve is by valve body, valve block, valve gap, plug, part such as moist closet and bimetallic strip is formed, cool air and condensed water when this drain valve can be got rid of initial launch in heating system or the heating equipment, the hot gas thermal insulation apparatus has been adopted in the valve block upper end, the frequency of valve block opening and closing descends, this drain valve reduces relatively than the serial drain valve steam leakage of TD, but this trap leaking amount still can not be satisfactory, and this drain valve only is provided with a weep hole, and weep hole is not arranged on the position of centre of gravity of valve block again, therefore, it is uneven steady to descend when valve block is closed, and easily produces eccentric wear, has shortened the working life of drain valve.
The inventor has applied for utility model patent in 1987 to State Intellectual Property Office, patent name is the heat power drain valve, the patent No. is ZL87201764, its task is to eliminate the shortcoming of above-mentioned two kinds of power drain valves, further reduce the leakage of steam, provide a kind of steam leakage few, the novel heat power drain valve of long service life, model utility heat power drain valve, through application and practice for many years, after nearly 6000 hours of work, the fastness between valve block and the spool, pick up bump ten thousand times through number, become mirror-like, condensed water just pushes away not open valve block, has promptly smothered, thereby cause valve can not get rid of condensed water, drain valve lost efficacy.
The model utility content
In view of this, the technical problems to be solved in the utility model is to provide a kind of modified model Shemostatic team trap, pass through the technical program, on valve block, be provided with the center of circle, and the capillary channel of symmetry, thereby the area of minute surface on the valve block reduced, prolong and back down the time, capillary channel has made things convenient for the discharge of condensed water, and has effectively stoped the leakage of working steam, thereby has effectively remedied the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that a kind of modified model Shemostatic team trap, include valve gap, valve body, spool, valve block and shell, described valve body both sides are respectively arranged with suction port and drain opening, above valve body, be provided with shell, be provided with the spool that is fixed on the valve body in the described shell, upper end at spool is provided with valve block, be provided with the valve gap that is fixed on the spool above the valve block, on spool, be respectively arranged with damping hole and air vent, described damping hole is connected with drain opening on the valve body, described damping hole is connected with drain opening by the valve channel on the valve body, and the lower end surface that is arranged on the valve block that is positioned at the spool upper end surface in the valve gap was provided with the capillary channel of the symmetry in the center of circle.
In the valve channel in the described valve body and the drain opening inboard of valve body is provided with the porous damping plate.
Be provided with filter screen between lower case and the spool in the described shell.
The technique effect that the utility model reaches is as follows: a kind of modified model Shemostatic team trap, the garden of crossing heart symmetry capillary channel by the technical program setting, reduced the minute surface area, prolong the time of backing down valve block, condensed water can successfully be discharged between capillary channel, and working steam but produces secondary steam by capillary channel, stops the escape of working steam, through facts have proved, the life-span extended to more than 9000 hours.
Description of drawings
Fig. 1 is a whole sectional structure schematic representation of the present utility model.
Among the figure, 1 shell, 2 valve gaps, 3 valve blocks, 4 capillary channel, 5 damping holes, 6 filter screens, 7 valve bodies, 8 suction ports, 9 porous damping plates, 10 drain opening, 11 valve channels, 12 air vents, 13 spools.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the modified model Shemostatic team trap that the utility model relates to, include valve gap 2, valve body 7, spool 13, valve block 3 and shell 1, described valve body 7 both sides are respectively arranged with suction port 8 and drain opening 10, above valve body 7, be provided with shell 1, be provided with the spool 13 that is fixed on the valve body 7 in the described shell 1, be provided with valve block 3 in the upper end of spool 13, be provided with the valve gap 2 that is fixed on the spool 13 above the valve block 3, on spool 13, be respectively arranged with damping hole 5 and air vent 12, described damping hole 5 is connected with drain opening 10 on the valve body 7, described damping hole 5 is connected with drain opening 10 by the valve channel on the valve body 7 11, and the lower end surface that is arranged on the valve block 3 that is positioned at spool 13 upper end surfaces in the valve gap 2 was provided with the symmetrical capillary channel 4 in the center of circle.
In the valve channel 11 in the described valve body 7 and drain opening 10 inboards of valve body 7 are provided with porous damping plate 9.
