Abstract
The utility model discloses a control valve structure which is characterized in that a valve housing is arranged in a valve body; the valve housing is arranged in an inner cavity of the valve body in an inclined mode; one end of the valve housing is connected with a valve cover; the valve cover is arranged on the surface of the valve body and in a sealing connection with the valve body; the other end of the valve housing is arranged in an inner cavity of the valve body and is communicated with an inlet end; a slide bushing brake is arranged in the valve housing; a sealing seat is arranged at the other end of the valve housing; the valve cover is provided with a valve rod; and the valve cover is in the sealing connection with the valve rod. The control valve structure has the advantages that: a guide and a brake hole are combined to form the valve housing, parts are reduced, and the installation and the maintenance are simpler and convenient. The design of a flow passage of the brake hole is reasonable, an included angle of a pressure cavity of the valve body is minimized as far as possible so that the design of the flow passage is lower to reduce flow resistance, the area of the brake hole is larger than or equal to that of a valve port so that the flow resistance is low and the flow capacity is large, and the vibration of the flow capacity is linear so that the adjustment scope is wide. The sealing seat is in a pressure assisted type so that rubber is not easy to be damaged because of squeeze, and the service life of the sealing seat is long.
Description
Technical field:
The utility model relates to the technical field of valve, a kind of specifically control valve structure, particularly its mechanical connecting structure.
Background technique:
At present, the design of most control valves has following deficiency: 1, the valve seat area of traditional control valve causes the big flow of flow resistance little less than the import bore.2, their sealing is the design of resisting valve seat with valve plate stubbornly, and the sealing of extruding type damages easily, causes leakage easily.3, their component of having are many, the more complicated that has, and the part difficult more assurance of multimass and maintenance more is also complicated.
Because the defective of above-mentioned technology, so still need existing control valve body structure is further improved.
The model utility content:
The purpose of this utility model is to provide a kind of control valve structure, valve flowing channel is reasonable in design, the big flow resistance of flow is low, transfer stream accurately thereby reach, long, few in light weight, the easy purpose of maintenance of component of sealing seat life-span has overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of control valve structure, it mainly comprises valve body, one end of valve body is provided with entrance point, then the other end of valve body is provided with outlet end, it is characterized in that: be provided with valve pocket in the described valve body, the oblique body cavity that is arranged at of valve pocket, one end of valve pocket is connected with valve gap, valve gap is arranged at valve body surface and is connected with valve seal, and the other end of valve pocket places body cavity and is connected with entrance point, is provided with the sliding sleeve lock in the valve pocket, the valve pocket the other end is provided with sealing seat, the valve gap place is provided with valve rod, and valve gap is connected with valve stem seal, and valve rod runs through valve gap, one end of valve rod places the valve gap outside, and the other end of valve rod is fixedlyed connected with sliding sleeve pocket floor portion.
The utility model discloses a kind of control valve structure, its advantage is dexterously guiding and lock hole disjunctor to be formed valve pocket, has reduced part and has made installation and maintenance more simple and convenient.The flow passage design of valve body reduces to minimum to the angle of valve body pressure chamber as far as possible, makes runner design lowlyer, to reduce flow resistance, the area in lock hole is more than or equal to the area of valve port, so the flow resistance low discharge is big, and changes in flow rate is that linear therefore regulation range is big.Sealing seat is the pressure auxiliary type, therefore can rubber be damaged, and the sealing seat life-span is long, and product has outstanding substantive distinguishing features and remarkable progress compared to existing technologies.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is a kind of control valve structure, it mainly comprises valve body 1, one end of valve body 1 is provided with entrance point 8, then the other end of valve body 1 is provided with outlet end 9, it is different from prior art and is: be provided with valve pocket 3 in the described valve body 1, valve pocket 3 oblique valve body 1 inner chambers that are arranged at, one end of valve pocket 3 is connected with valve gap 2, valve gap 2 is arranged at valve body 1 surface and is tightly connected with valve body 1, and valve gap is fixed on valve pocket in the valve body, and the other end of valve pocket 3 places valve body 1 inner chamber and is connected with entrance point 8, be provided with sliding sleeve lock 4 in the valve pocket 3, valve pocket 3 the other ends are provided with sealing seat 5, and valve gap 2 places are provided with valve rod 7, and valve gap 2 is tightly connected with valve rod 7, valve rod 7 runs through valve gap 2, one end of valve rod 7 places valve gap 2 outsides, and the other end of valve rod 7 is fixedlyed connected with sliding sleeve lock 4 bottoms, during use as long as the aperture that actuate valve stem up and down can control valve.
In the specific implementation, described sliding sleeve lock 4 upper ends are provided with Sealing 6, and sliding sleeve lock 4 is slidingly connected with valve pocket 3 inner wall sealings, and described Sealing 6 is a seal ring.
In the specific implementation, described valve gap 2 centre bits are provided with valve rod 7, are connected for slipper seal between valve rod 7 and the valve gap 2.
In the specific implementation, described sliding sleeve lock 4 bottoms are provided with vent 10, in order to reduce the pressure reduction of sliding sleeve lock.
The critical piece of this control valve has only valve body, valve gap, valve pocket, sliding sleeve lock and sealing seat, does not have quick-wear part except Sealing, only needs when changing Sealing valve gap is opened, and taking out the sliding sleeve lock is replaceable Sealing.
Valve of the present utility model is little in the needs flow resistance, and flow is big, and when pressure reduction was little, entrance point and outlet end can exchange, and the valve body entrance point that is about to this valve uses as outlet end, and the valve outlet end of this valve is used as entrance point.
The outlet lock hole of valve of the present utility model can be designed according to different needs, and the high pressure energy dissipating then can be made up of many spray orifices if desired, and the shape that different if desired control curves then can change exit orifice achieves the goal
The utility model has the advantages that the flow passage design of valve body, guiding and lock hole disjunctor form valve pocket so that valve mechanism is simple, and installation and maintenance are convenient, the flow resistance low discharge is big, big and the changes in flow rate of adjustable range is linear, and it is easy to change seal, and the seal receptacle life-span is long. Can be according to different needs with electronic, hydraulic pressure or manually control.
