Abstract
The utility model relates to a diaphragm mud valve provided with a valve rod protecting cover. The diaphragm mud valve provided with the valve rod protecting cover comprises a valve rod (1), a valve plate (2) and a diaphragm (3); a stepped groove (5) is arranged at the center of the valve plate (2) of a sealing seat (4); a half snap ring (6) is arranged inside the groove (5); a fixed half snap ring plate (7) is arranged above the half snap ring (6); the lower end of the valve rod (1) is fixedly connected with the half snap ring (6); the upper end of the valve rod (1) is fixedly connected with the diaphragm (3); a protecting cover (8) is fixedly connected outside the valve rod (1); the upper end of the protecting cover (8) is fixedly connected with the sealing seat (4), and the lower end of the protecting cover (8) is fixedly connected with the fixed half snap ring plate (7). After the technical scheme is adopted, sediment is prevented outside the protecting cover and does not enter a diaphragm seat through a gap between the upper end of the valve rod and the diaphragm seat when the diaphragm mud valve removes sludge or waste water. Therefore, the diaphragm is protected, and meanwhile, the situation that the valve rod is not corroded is also ensured, and the service life of the device is prolonged.
Description
Technical field
The utility model relates to a kind of Diaphram type mud discharging valve that is provided with protective housing.
Background technique
Soil discharging valve has another name called and covers valve, be usually used in the deposition tank of city water factory, sewage treatment works at the bottom of discharging mud use.The Applicable media of soil discharging valve is native sewage water, and the temperature of medium generally should be less than 50 ℃, and its operating depth is less than 10 meters, and soil discharging valve also is used for water treatment plant as mud and waste water in the discharging pond.Diaphram type mud discharging valve is that a kind of angle type of doing actuator by hydraulic power or pneumatic source blocks the class valve, usually in a row is installed in deposition tank bottom outside wall, in order to get rid of silt particle and the dirt of precipitation at the bottom of the pond.Membrane type quick-opening mud valve is divided into two chambers by nylon reinforcing rubber barrier film with valve, connects hydraulic pressure or pneumatic source, adopts electronic or manual two-position four way change valve control, realizes beginning to rehearse soon mud.
Membrane type quick-opening mud valve generally contains the compositions such as valve gap, diaphragm pressing plate, diaphragm, diaphragm seat, valve rod, valve plate, valve body, two-position four-way solenoid directional control valve.Existing Diaphram type mud discharging valve is when getting rid of mud and waste water, valve rod is corroded by waste water easily on the one hand, solid particle in the waste water often enters the diaphragm seat by the slit between valve rod upper end and diaphragm seat easily on the other hand, solid particle is Impact Diaphragm under the effect of pressure, diaphragm is damaged cause leaking and then causes equipment to work easily like this.
The model utility content
The utility model is corroded easily in order to solve valve rod, the solid particle in the waste water often easily by valve rod upper end and the problem that the slit between the diaphragm seat enters diaphragm seat damage diaphragm, provides a kind of Diaphram type mud discharging valve that is provided with protective housing.
The technical solution adopted in the utility model is: a kind of Diaphram type mud discharging valve that is provided with the valve rod protective housing, it comprises valve rod, valve plate, diaphragm, sealing seat, described valve plate central authorities are provided with step-like groove, it is characterized in that being provided with in the described groove half snap ring, half snap ring top is provided with fixes half snap ring plate, described valve rod lower end is fixedly connected with half snap ring, and the valve rod upper end is fixedly connected with diaphragm; Described valve rod is connected with protective housing outward, and the upper end of protective housing is fixedly connected with sealing seat, the lower end with fix half snap ring plate and be fixedly connected with.
As further improvement of the utility model, described protective housing is bellows.
The beneficial effect that the utility model adopts is: after having adopted this technological scheme; owing to outside valve rod, be provided with protective housing; Diaphram type mud discharging valve is when getting rid of mud and waste water; silt can be blocked in outside the protective housing; and can not enter the diaphragm seat by the slit between valve rod upper end and diaphragm seat; protected like this diaphragm, guaranteed that also valve rod can not be corroded, and has prolonged the working life of equipment simultaneously.
Description of drawings
Fig. 1 is the utility model schematic representation.
Shown in the figure: 1, valve rod, 2, valve plate, 3, diaphragm, 4, sealing seat, 5, groove, 6, half snap ring, 7, fix half snap ring plate, 8, protective housing.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, a kind of Diaphram type mud discharging valve that is provided with the valve rod protective housing, it comprises valve rod 1, valve plate 2, diaphragm 3, sealing seat 4, described valve plate 2 central authorities are provided with step-like groove 5, it is characterized in that being provided with in the described groove 5 half snap ring 6, half snap ring top 6 is provided with fixes half snap ring plate 7, and described valve rod 1 lower end is fixedly connected with half snap ring 6, and valve rod 1 upper end is fixedly connected with diaphragm 3; Be connected with protective housing 8 outside the described valve rod 1, the upper end of protective housing 8 is fixedly connected with sealing seat 4, and the lower end is fixedly connected with fixing half snap ring plate 7, and described protective housing 8 is bellows.
After having adopted this technological scheme; owing to outside valve rod, be provided with protective housing; Diaphram type mud discharging valve is when getting rid of mud and waste water; the solid particles such as silt can be blocked in outside the protective housing; and can not enter the diaphragm seat by the slit between valve rod upper end and diaphragm seat; protected like this diaphragm, guaranteed that also valve rod can not be corroded, and has prolonged the working life of equipment simultaneously.
