Description
Technical field:
This utility model relates to Outside screw stem rising through handwheel type gate valve field, particularly a kind of hard seal gate valve of rustless steel rising stem (RS.).
Background technology:
The opening and closing element of Outside screw stem rising through handwheel type gate valve is flashboard, and the direction of motion of flashboard is perpendicular with flow direction, and gate valve can only make standard-sized sheet and Quan Guan, it is impossible to makes adjustments and throttles.
The shortcoming of Outside screw stem rising through handwheel type gate valve is as follows:
Easily cause erosion and scratch between sealing surface, keep in repair relatively difficult；Overall dimensions is relatively big, opens and needs certain space, and opening/closing time is long；Structure is more complicated.
Utility model content:
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of hard seal gate valve of rustless steel rising stem (RS.) provided.
The technical solution adopted in the utility model is:
The hard seal gate valve of rustless steel rising stem (RS.), including valve body, it is characterized in that: be provided with kidney-shaped cavity in described valve body and be slidably fitted with flap, flap central authorities are provided with female thread, valve outer wall is provided with platform and is provided with fixing seat, is rotatablely equipped with screw rod in fixing seat, and screw rod is through flap and screws togather with it, the lower end of screw rod rotates and is installed on kidney-shaped cavity lower end inner wall, and the upper end of screw rod is connected to handle.
The described hard seal gate valve of rustless steel rising stem (RS.), it is characterised in that: described handle and screw rod upper end thereof.
Compared with prior art, the beneficial effects of the utility model are in that:
This utility model structural design is simple and ingenious, it is possible to effectively the structure of Outside screw stem rising through handwheel type gate valve simplified, and simple to operate, conveniently manufactures and uses, and under the premise ensureing gate valve function, structure is enough simple.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
Below in conjunction with accompanying drawing, by embodiment, this utility model is described in further detail:
The hard seal gate valve of rustless steel rising stem (RS.), including valve body 1, it is provided with kidney-shaped cavity in valve body 1 and is slidably fitted with flap 2, flap 2 central authorities are provided with female thread, valve body 1 outer wall is provided with platform and is provided with fixing seat 3, is rotatablely equipped with screw rod 4 in fixing seat 3, and screw rod 4 is through flap 2 and screws togather with it, the lower end of screw rod 4 rotates and is installed on kidney-shaped cavity lower end inner wall, and the upper end of screw rod 4 is connected to handle 5.
Above-described embodiment is only preferably embodiment of the present utility model, and in addition, this utility model can also have other implementations.It should be noted that under the premise conceived without departing from this utility model, any conspicuously improved and modification all should fall within protection domain of the present utility model.
