Abstract

The utility model discloses a gate valve with prolong long handle, including the ball valve body with install the handle in ball valve body upper end, still be provided with handle extension section, handle extension section is through the terminal swing joint of pivot and handle, is the rotation angle scope of handle extension section 0 90. Compared with the prior art, the utility model discloses is in the terminal active connection handles extension section of handle, and the rotation angle scope 0 90, the unable pivoted circumstances of handle is appearing, with handle extension section rotatory to with the laggard line operate of handle level, when having increased moment, guaranteed operating personnel's safety.

Description

With the gate valve for extending handle

Technical field

This utility model is related to a kind of gate valve, specifically a kind of with the gate valve for extending handle, belongs to ball valve technology neck Domain.

Background technology

Gate valve is the valve class wanted.Ball valve is mainly used in blocking or connects medium, it can also be used to the regulation and control of fluid, extensively The general operating mode for requiring strict cut-out suitable for oil, chemical industry, urban water supply and sewerage etc..

Existing gate valve, as use environment is mostly relatively more severe, its handle portion lease making often causes nothing because of extraneous corrosion Method is rotated, and generally requires external force, such as extends torque using sleeve pipe, and aforesaid way often because rubber sleeve or other operations not When danger is caused, harm is brought to operator personnel.

The content of the invention

For the problem that above-mentioned prior art is present, this utility model provides a kind of with the gate valve for extending handle, operation Simply, it is ensured that installation personnel safety.

To achieve these goals, this utility model includes ball valve body and the handle installed in ball valve body upper end, also Handle extension is provided with, handle extension is flexibly connected with handle end by rotating shaft, the anglec of rotation model of handle extension Enclose for 0 ° -90 °.

Further, handle extension arrange it is multiple, between by rotating shaft be flexibly connected, fold be arranged on handle end End；Handle extension rotation angle range from each other is 0 ° -90 °.

Further, handle prolongation segment length is consistent.

Further, layer protective layer is provided with the outside of handle extension, and described protective layer uses flannelette or rubber For material.

Further, retaining spring is carried in rotating shaft.

Contrast prior art, this utility model are flexibly connected handle extension in handle end, and rotation angle range is 0 ° -90 °, there is the situation that handle cannot be rotated, by handle extension rotate to handle level after operated, increased While torque, it is ensured that the safety of operator.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in figure 1, it is a kind of with the gate valve for extending handle, including ball valve body 1 and installed in 1 upper end of ball valve body Handle 2；Handle extension 3 is additionally provided with, described handle extension 3 is flexibly connected with 2 end of handle by rotating shaft 4, described Handle extension 3 rotation angle range be 0 ° -90 °.

Further improve as this utility model, handle extension 3 arranges multiple, between by the activity of rotating shaft 4 even Connect, fold installed in the end of handle 2；The rotation angle range from each other of handle extension 3 is 0 ° -90 °.

Further improve as this utility model, 3 length of handle extension is consistent.

Further improve as this utility model, the outside of handle extension 3 is provided with layer protective layer, described guarantor It is material that sheath uses flannelette or rubber.

Further improve as this utility model, in rotating shaft 4, carry retaining spring.
