Abstract
The utility model relates to a novel valve bellow seal structure, which is characterized by comprising a seal bellow which is provided with a seal disc, a valve core and a locknut, wherein the seal bellow which is provided with the seal disc is placed in the valve body, the valve core is placed in the seal bellow which is provided with a seal disc, the locknut is sleeved on a metal valve rod, the metal valve rod which is provided with the locknut is connected with the valve core, a valve lid is placed on a seal disc of the metal bellow tube for fixing a sleeve. The novel valve bellow seal structure has the advantages that 1. the valve core and the bellow are composed individually and are convenient to change and reduce cost when damaged, 2. the bellow doesn't expose in the dielectric sprue, thereby lengthening use life, 3. the groove shape of the bellow is changed and adopts the inclined angular groove, which is easier to prepare and doesn't generate chip jam in the preparation procedure.
Description
Technical field
The utility model relates to a modulating valve, particularly a kind of novel valve sylphon seal structure.
Background technique
Therefore the sealing configuration of existing modulating valve valve bellows, seal bellows and spool are structure as a whole and are exposed in the medium runner, have media particles easily in the bellows slit and are subjected to the erosion of medium, cause bellows to damage; The flute profile of seal bellows is a U-groove bevel, causes smear metal to stop up the processing inconvenience in course of working easily.
Summary of the invention
In view of the deficiency that prior art exists, it is that split is formed with bellows that the utility model provides a kind of corrosion-resistant, spool, and bellows is not exposed to the interior a kind of novel valve sylphon seal structure of medium runner.
The technological scheme that the utility model is taked for achieving the above object is, a kind of novel valve sylphon seal structure, comprise the overcoat that valve body is housed, the spool that is connected as a single entity with seal bellows, metal valve stem, valve gap, it is characterized in that: also comprise the seal bellows of being with seal disc, spool and locknut, the bellows of described band seal disc places in the valve body, described spool places in the seal bellows that has seal disc, described locknut is inserted on the metal valve stem, the metal valve stem that has locknut is connected with spool, and described valve gap places on the seal disc of metal bellows and fixes with overcoat.
The utility model beneficial effect is:
1, spool and bellows are that two-part are formed, and change convenient and minimizing expense during damage.
2, bellows is not exposed in the medium runner, has prolonged working life.
3, the flute profile of bellows changes, and has adopted the angle groove that tilts, and processing is more prone to, and can not cause smear metal obstruction in the processing.
Description of drawings
Fig. 1 is the utility model structural representation and as Figure of abstract.
Embodiment
The valve body 2 of the fluoroplastic material of in metal-coating 4, packing into as shown in Figure 1, two ends clamp with 1 pair of the metal flange that metal retainer 3 is housed joins, the spool 6 of PTFE material is put into the seal bellows 5 of PTFE material, locknut 7 is screwed on the metal valve stem 8, the metal valve stem 8 that will have locknut 7 again is threaded with spool 6, with locknut 7 spool 6 is locked then, this moment, locknut 7 and spool 6 clamped the upper end of seal bellowss 5, integral body was put into valve body 2 after more than assembling was finished, this moment, inserted in the valve seat orifice of valve body 2 at the tip of spool 6, at last, buckle valve gap 9, valve gap 9 one ends are pressed on the seal disc of seal bellows 5, and this moment, valve gap 9 clamped the seal disc of seal bellowss 5 with valve body 2, and valve gap 9 and overcoat 4 are fixed with stud nut.During use metal valve gap 9 is opened, the disc head of outside connecting rod is inserted in the T-slot of metal valve stem 8, in the most advanced and sophisticated valve seat orifice of inserting valve bodies 2 of spool 6, metal valve gap 9 clamps seal bellowss 5 and fastening with stud nut with valve body 2.
The groove of above-mentioned seal bellows 5 has adopted the angle groove 10 (being in the shape of the letter V) that tilts.
The active sulfur body medium flows into valve body 2 from import, and valve rod 8 drives the spools 6 motion controls mouthful switching amount of damming, thus the control rate of discharge.In stream, the spool 6 and seal bellows 5 materials that contact with the active sulfur body medium are PTFE, and valve body 2 materials are fluoroplastic, have guaranteed good anti-corrosion.
Claims (4)
1, a kind of novel valve sylphon seal structure, comprise the overcoat (4) that valve body (2) are housed, the spool (6) that is connected as a single entity with seal bellows (5), metal valve stem (8), valve gap (9), it is characterized in that: also comprise the seal bellows (5) of being with seal disc, spool (6) and locknut (7), the bellows of described band seal disc (5) places in the valve body (2), described spool (6) places in the seal bellows (5) that has seal disc, described locknut (7) is inserted on the metal valve stem (8), the metal valve stem (8) that has locknut (7) is connected with spool (6), and described valve gap (9) places on the seal disc of metal bellows (5) fixing with overcoat (4).
2. according to the described novel valve sylphon seal of claim 1 structure, it is characterized in that described valve body (2) is the fluoroplastic material.
3. according to the described novel valve sylphon seal of claim 1 structure, it is characterized in that described spool (6), seal bellows (5) are the PTFE material.
