Abstract
The utility model discloses a column through valve, and relates to an improvement on a plunger valve which controls the flow capacity of medium. The utility model comprises a valve body, a valve cover, a valve column, a support frame, an upper sealing ring, a lower sealing ring, a valve rod, and a driving mechanism. The valve column is provided with inner holes which are communicated. One end of the inner holes is communicated with an inlet, and the other end of the inner holes is communicated with an outlet. The inner holes are a hole A and a hole B which are vertically communicated. The utility model has the advantages that the isolation of the sealing ring and the medium is effectively guaranteed, the difficult problem of the internal leakage of the valve is solved, the applicable temperature range and the commonality of the medium are enlarged, and the service life of the valve is greatly improved.
Description
The utility model relates to the improvement of plunger valve, is applicable to the control of various flowing medium flows in all pipelines.
The plunger valve of producing, selling and uying both at home and abroad at present, the seal ring of its valve rod bottom directly contacts with medium for a long time in opening state, causes the sealing surface corrosion and damage, leaks in causing easily, simultaneously the valve rod opening state is in unidirectional support location, is subjected to the influence of pressure medium easily and damages seepage.
In view of the deficiency that prior art exists, the purpose of this utility model aims to provide the Column through valve of a kind of sealing surface and media isolated.
Another purpose of the present utility model aims to provide the Column through valve of the two-way location of a kind of valve rod.
The utility model is finished as follows: the utility model comprises valve body, valve gap, valve rod, support, upper and lower seal ring, valve rod, driving mechanism, described valve rod is provided with the endoporus that communicates, this endoporus one end communicates with inlet, and the other end communicates with outlet.
Hole A and the hole B of above-mentioned endoporus for vertically communicating, hole A is located at the bottom of valve rod, and the one end communicates with inlet, and hole B is located at the sidepiece of valve rod, and its other end communicates with outlet.
The quantity of above-mentioned endoporus can design a plurality of according to demand.
The utility model has compared with prior art been realized effective isolation of medium and seal ring, has solved the difficult problem of the easy seepage of valve, has increased the Applicable temperature and the Applicable scope of medium, the working life of having improved valve greatly.
The utility model has following accompanying drawing
Fig. 1 is the utility model opening state structural representation
Fig. 2 is the utility model closed condition structural representation
Fig. 3 is the structural representation of valve rod in the utility model
Accompanying drawing has been represented structure of the present utility model, in conjunction with the embodiments structure of the present utility model and principle thereof is further elaborated below again.The utility model comprises valve body 1, valve gap 2, valve rod 3, support 4, upper- lower seal circle 5,8, valve rod 6, driving mechanism 7, and described valve rod 3 is provided with the endoporus that communicates, and this endoporus one end communicates with inlet, and the other end communicates with outlet.Present embodiment adopts two hole A that vertically communicates and hole B, and hole A is located at the bottom of valve rod, and the one end communicates with inlet, and hole B is located at the sidepiece of valve rod, and its other end communicates with outlet, and the quantity of hole A and hole B can be a plurality of according to the Demand Design of valve.Medium enters from the valve rod 3 endoporus A of valve, flows out by valve rod 3 endoporus B, and by the size that driving mechanism is regulated rate-of flow arbitrarily, described driving mechanism can adopt drive units such as manual, pneumatic or electronic.In the utility model, the unlatching of valve, to close be finish by moving in the upper and lower seal ring of valve rod 3 in valve body, the position of valve rod 3 is in the upper and lower seal ring of support all the time, and carries out two-way location by upper and lower seal ring, reduces valve rod and is subjected to pressure medium and damages seepage.Adopt the utility model structure, utilize the endoporus that communicates on the valve rod dexterously, reach medium and seal ring and isolate, solved the interior easily difficult problem of leaking of valve, and medium Applicable temperature scope and media general have been enlarged, guaranteed the working life of valve rod and seal ring, its simple and ingenious structure, easy to use, sealing is tight, durable in use, be widely used, be one of traditional plunger valve to be created greatly change.
