Abstract
The utility model relates to the technical field of valves, in particular to a novel heating control stop valve without leakage. The novel heating control stop valve is characterized that the novel heating control stop valve comprises a valve body, a check valve plate, a valve sleeve, macromolecule sealing, a check spring, a connecting sleeve, a valve cover and a valve rod sleeve. In the novel heating control stop valve without leakage, the macromolecule sealing is arranged at the valve plate surface of the check valve plate; the macromolecule sealing is coated on the obverse side of the check valve plate to prevent a valve chamber from leaking and being corroded. Both ends of the check spring are provided with the valve sleeve and the valve rod sleeve, so that the check valve spring is protected by the valve sleeve and the valve rod sleeve; the upper end of the check spring is connected with the valve rod sleeve; the valve sleeve is arranged at the lower end of the check spring, so as to avoid the failure of the valve caused by the corrosion fracture at the weak and most easily corroded parts of both ends of the spring.
Description
Technical field
The present invention relates to valve technology field, especially a kind of new heat-supplying does not have the control of leakage stop valve.
Background technique
The rubber seal under High Temperature High Pressure of traditional stop valve is leaked easily, thereby has lost effect, and under the high temperature of long-term corrosion, spring two is the most perishable, causes spring to rupture easily, and rubber sealing also lost efficacy easily, and valve was lost efficacy easily.
Summary of the invention
At the problems referred to above, the utility model provides following technological scheme: a kind of new heat-supplying does not have the control of leakage stop valve, it is characterized in that, comprise: valve body 1, check valve plate 2, valve pocket 3, polymeric seal 4, check spring 5, connecting sleeve 6, valve gap 7, valve stem casing 8, described a kind of new heat-supplying does not have that to reveal the control stop valve be that valve plate face at check valve plate 2 is provided with polymeric seal 4, described polymeric seal 4 spreads upon the front by the check valve plate 2 of medium, prevents that valve pocket from revealing and corrosion.Described check spring 5 two are provided with valve pocket 3 and valve stem casing 8; make check spring 5 obtain the protection of valve pocket 3 and valve stem casing 8; described check spring 5 upper ends link to each other with valve stem casing 8; described check spring 5 lower ends are equipped with valve pocket 3; avoided the easiest corrosion place of spring two weakness; corrosion fracture causes valve invalidation.
The invention has the beneficial effects as follows: 1. strengthen anticorrosion effect; 2. avoided spring breakage; 3. save material and reach energy-saving effect.
Description of drawings
Fig. 1 is that a kind of new heat-supplying does not have the control of leakage stop valve structure schematic representation.
Valve body 1, check valve plate 2, valve pocket 3, polymeric seal 4, check spring 5, connecting sleeve 6, valve gap 7, valve stem casing 8.
Embodiment
Shown in Figure 1, described a kind of new heat-supplying does not have that to reveal the control stop valve be that valve plate face at check valve plate 2 is provided with polymeric seal 4, and described polymeric seal 4 spreads upon the front of check valve plate 2, is exactly the direction towards medium, prevents that valve pocket from revealing and corrosion.Described check spring 5 two obtain the protection of valve pocket 3 and valve stem casing 8, and described check spring 5 upper ends are provided with valve stem casing 8 and are attached thereto; described check spring 5 lower ends are equipped with valve pocket 3; avoided the easiest corrosion place of spring two weakness, corrosion fracture causes valve invalidation.
Claims (1)
1. a new heat-supplying does not have the control of leakage stop valve, it is characterized in that, comprise: valve body, check valve plate, valve pocket, polymeric seal, check spring, connecting sleeve, valve gap, valve stem casing, it is to be provided with polymeric seal at check valve plate that described a kind of new heat-supplying does not have the control of leakage stop valve, described polymeric seal is the front that spreads upon check valve plate, described check spring two is provided with valve pocket and valve stem casing, and described check spring upper end is provided with valve stem casing, and valve pocket is installed in the lower end.
