Abstract
The utility model discloses a water power control valve, which is characterized in that an elastic sleeve and a membrane are arranged in a valve body and a flange cover provided with a supporting rod is arranged at the two sides of the valve body. As a sealing base and a supporting block are arranged between a left valve body and a right valve body, and the supporting rod is arranged at the two sides of a valve rod, the utility model improves the centering of a gate plate and rigidity of the gate plate and the valve rod to avoid shearing phenomenon of the sealing base and greatly improve the stress condition of the valve plate. The water power control valve not only has small hoist moment, but also has long service life, and improved sealing effects which meets requirements of clients.
Description
Technical field:
The utility model relates to the technical field of valve, specifically a kind of improved hydraulic control valve.
Background technique:
There is complex structure in present control valve, be installed in and mostly still have flow and the unmanageable deficiency of pressure in the pipeline, also there are the phenomenon of closing not closely, leaking in some electric gate valves or butterfly valve, make greatly reduce the working life of gate valve, at starting mode of pump or when out of service, also might produce the phenomenon of water hammer, this has influenced the using scope of control valve to a great extent.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved hydraulic control valve, and it can overcome some shortcomings of the prior art.
The technical solution of the utility model is achieved in that hydraulic control valve, it mainly comprises valve body, is contained in the spool in the valve body, is contained in the blind flange of valve body both sides, it is characterized in that: elastic sleeve and barrier film are housed in valve body, in the blind flange of valve body both sides, are provided with supporting rod.
The utility model is owing to be equipped with elastic sleeve and barrier film in valve body, in the blind flange of valve body both sides, be provided with supporting rod, utilize this barrier film, valve body is separated into two-chamber, thereby rely on the keying degree that is used for controlling barrier film of the pressure medium of fluid and pilot valve to reach comparatively desirable water control state, and improved sealing effect, long service life, easy and simple to handle reliable, also can prevent the phenomenon of water hammer, this control valve can be widely used in the fluid lines such as tap water, sewage, building, food, energy fire-fighting.
Description of drawings:
Fig. 1 is the utility model one embodiment's a structural representation
Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises valve body 1, be contained in the spool 2 in the valve body 1, be contained in the blind flange 3 of valve body both sides, it is characterized in that: elastic sleeve 4 and barrier film 5 are housed in valve body 1, make two control chambers of the interior formation of blind flange of both sides, in the blind flange 3 of valve body both sides, be provided with supporting rod 6; Barrier film is a tubular diaphragm during concrete enforcement, the two end part of this barrier film extend in the valve body and the joint of blind flange, neutral position near barrier film is sleeved in the elastic sleeve, the supporting rod that is arranged in the blind flange all extends in the valve body, the other end of the supporting rod 6 of present embodiment in valve body 1 one side flanges lid 3 extends in the valve body, one end of the supporting rod 6 in valve body 1 opposite side blind flange 3 passes spool and extends in the valve body, the supporting rod that promptly is arranged in the blind flange of valve body both sides all extends in the valve body, one end of the supporting rod in valve body one side flange lid is packed in the blind flange, the other end extends in the valve body, one end of the supporting rod in valve body opposite side blind flange passes spool and extends in the valve body, the other end of this supporting rod is packed in the blind flange, supporting rod passes nut 7 in the time of fixedly, makes supporting rod fixedly connected with spool.The utility model is under the situation that spool is under pressure, force the tubular diaphragm distortion, medium compressing control chamber, working as external pipeline during use closes, when water intake arrives control chamber, this moment, valve was closed condition, when the external pipeline standard-sized sheet, pressure in the control chamber is discharged into the outside, this time gating is the full open state, regulate the aperture of external pipeline pilot valve, be placed in the compressing of the qualification pressure in the outer controlled chamber of enhancing elastic sleeve of tubular diaphragm, control chamber only release portion pressure is extremely extraneous, this moment, the aperture of valve was intermediateness, according to the purpose of using, the difference of function and occasion, as dispose certain external control pipeline and secondary valve, this valve is applicable to remote control, decompression, buffer valve and other control aspect to flow.
