Abstract
The utility model relates to a multipurpose corrugated pipe gate valve which comprises a valve body, a gate plate, a valve cap and valve rods, wherein the valve cap is fixedly connected with the valve body and the valve rods and the gate plate which are movably connected with the valve cap are in transmission connection. The valve rods are divided into an upper valve rod and a lower valve rod, wherein the upper valve rod is radially and movably, and axially and fixedly connected with the valve cap, the upper end of the lower valve cap is in thread and transmission connection with the upper valve rod and the lower end of the lower valve rod is fixedly connected with the gate plate. The utility model has the advantages that because the valve rods are composed of the upper valve rod and the lower valve rod which are connected in thread transmission, the condition that the original sliding channel of the lifting switch of the blind rod type gate valve is arranged in the gate valve is changed into the condition that the original sliding channel is in thread transmission of the upper and the lower valve rods; the gate plates and the valve bodies of the open rod type and the blind rod type gate valves are unified, and the interchange ability can be realized; the product specification is uniform; the cost is low; the production management is simplified. The valve cap and the valve rods use corrugate pipes to be sealed, the dynamic seal is changed into the static seal so that the sealing effect is good and the zero leakage can be realized.
Description
Technical field:
The utility model relates to a kind of valve, relates in particular to a kind of gate valve.
Background technique:
As everyone knows, gate valve is a kind of common valve, generally comprise valve body, valve rod, valve gap, open-shut device (flashboard) etc., open-shut device (flashboard) moves and the function that realizes opening and closing along the Vertical direction of path center line, main rising cut off the mobilization that is transferred medium on pipeline, the gate valve of prior art can be divided into two kinds by structure, and a kind of is the blind rod type gate valve, and another kind is a rising stem gate valve.Porose in the middle of the flashboard of blind rod type gate valve, the flashboard body is thick, and the flashboard of rising stem gate valve is solid, middle atresia, the flashboard body is thin, thereby the valve body supporting with it also has nothing in common with each other, the flashboard and the valve body of two kinds of gate valves do not have interchangeability, have the production management complexity, the shortcoming that cost is high.
Summary of the invention:
The purpose of this utility model is to propose the bellows gate valve of a kind of flashboard and the light and shade dual-purpose that valve body can exchange, cost of production is low.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: Multi-purpose Corrugated Pipe Discharge Gate, comprise valve body, flashboard, valve gap and valve rod, valve gap is fixedlyed connected with valve body, the valve rod and the flashboard that flexibly connect with valve gap are in transmission connection, described valve rod is divided into upper valve rod and lower valve rod, upper valve rod is radially movable with valve gap, axial restraint is connected, and the upper end of lower valve rod and upper valve rod screw thread are in transmission connection, and fixedlys connected with flashboard in the lower end of lower valve rod.
The beneficial effects of the utility model are: because valve rod is made up of upper valve rod that is in transmission connection as screw thread and lower valve rod, the sliding channel that makes the original direction switch of blind rod type gate valve is by in flashboard and during the screw thread transmission of transferring to upper valve rod and lower valve rod cooperates, the flashboard and the valve body of rising stem (RS.) and inside screw non-rising stem type gate valve are united, realize interchangeability, thereby the utlity model has the advantage that product specification is unified, cost of production is low, production management is simplified.As further improvement, adopt sylphon seal between valve gap and the valve rod, change is sealed into static seal, makes sealing effect better, can realize zero leakage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, Multi-purpose Corrugated Pipe Discharge Gate, comprise valve body 1, flashboard 2, valve gap 3 and valve rod, valve gap 2 is fixedlyed connected with valve body 1, the valve rod and the flashboard 3 that flexibly connect with valve gap 2 are in transmission connection, and described valve rod is divided into upper valve rod 4 and lower valve rod 5, and upper valve rod 4 is radially movable with valve gap 2, axial restraint is connected, the upper end of lower valve rod 5 and upper valve rod 4 screw threads are in transmission connection, and fixedly connected with flashboard 3 in the lower end of lower valve rod 5.Be arranged with the bellows component 6 with valve gap 2 fixed seal connections on the described lower valve rod 5, lower valve rod 5 and also fixed seal connection of bellows component 6.
Its working procedure is as follows: rotate handwheel 7 drive upper valve rods 4 then mobile, its termination trapezoidal thread drives lower valve rod 5.Bellows component 6 compress bellows and mention the unlatching that flashboard 2 has been finished gate valve.When rotation hand wheel 7 round about, then drive upper valve rod 4 round about then do not move, its termination trapezoidal thread promotes flashboard 2 and has finished closing of gate valve because of rotation drives lower valve rod 5.
