Abstract

The utility model relates to a handle butterfly valve, its characterized in that: the electric iron comprises a handle, the fluted disc, a valve body, valve rod and butterfly plate, the coaxial valve neck that passes valve body upper portion of valve rod, the ring flange coaxial fixed mounted fluted disc of valve neck upper end, rotate and sealing connection between valve stem end and the valve neck, the handle is adorned radially admittedly to the valve rod upper end, turning handle drive valve rod rotates, the butterfly plate is established in the valve body, valve rod and butterfly plate fixed connection, handle lower part hinge dress braking handle, braking handle front end is embedded into in the tooth of fluted disc, carry out rigidity to the handle, the fluorescent rubber wear strip is equipped with admittedly at upper surface interval at the handle. The utility model provides a handle butterfly valve is applicable to puts position relatively poor in the light condition or that light is insufficient, is equipped with the fluorescent rubber wear strip admittedly at handle upper surface interval, when daytime light not good, or the black matrix time, the user can be rapid finds the handle of valve, guarantees the security of pipeline.

Description

Handle butterfly valve

Technical field

The utility model belongs to valve field, is a kind of handle butterfly valve.

Background technology

Handle butterfly valve structure is simple, volume is little, lightweight, only formed by a few parts. And only need half-twist to get final product fast opening and closing, simple to operate, this valve has good fluid control characteristic simultaneously. Butterfly valve is in the time of full open position, and butterfly plate thickness is MEDIA FLOW unique resistance in the time of valve body, and the Pressure Drop therefore producing by this valve is very little, therefore have good metering characteristics.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, install convenient, under the condition of light difference, can know display position handle butterfly valve.

The technical scheme that the utility model is realized object is as follows:

A kind of handle butterfly valve, comprise handle, fluted disc, valve body, valve rod and butterfly plate, valve rod coaxially passes the valve neck on valve body top, the ring flange of valve neck upper end is coaxially fixedly mounted with fluted disc, between valve rod end and valve neck, rotate and be tightly connected, valve rod upper end is radially fixedly mounted with handle, turning handle actuate valve stem is rotated, butterfly plate is located in valve body, valve rod is fixedly connected with butterfly plate, handle bottom hinge dress brake handle, and brake handle front end is embedded in the tooth of fluted disc, handle is carried out to position and fix, be fixed with fluorescence rubber chafing strip at the upper surface interval of handle.

And, be shaped with direction fluorescence rubber arrow at fluted disc upper surface.

And, being shaped with annular groove at the upper surface interval of handle, fluorescence rubber bar is inlaid in annular groove.

The beneficial effects of the utility model are:

The handle butterfly valve that the utility model provides is applicable to be placed on the poor or insufficient position of light of light condition, be fixed with fluorescence rubber chafing strip at handle upper surface interval, when daytime light bad, or when black matrix, user can find the handle of valve rapidly, ensures the security of pipeline.

The handle butterfly valve that the utility model provides is fixedly mounted with two bar fluorescence rubber bars at fluted disc upper surface, can clearly indicate the direction of valve rotation, ensures the security of pipeline.

Brief description of the drawings

Fig. 1 is front view of the present utility model;

Fig. 2 is the top view of fluted disc part.

Detailed description of the invention

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of handle butterfly valve, comprise handle 1, fluted disc 2, valve body 5, valve rod (not shown) and butterfly plate 6, valve rod coaxially passes the valve neck 4 on valve body top, the ring flange 3 of valve neck upper end is coaxially fixedly mounted with fluted disc, between valve rod end and valve neck, rotate and be tightly connected, valve rod upper end is radially fixedly mounted with handle, turning handle actuate valve stem is rotated, butterfly plate is located in valve body, valve rod is fixedly connected with butterfly plate, handle bottom hinge dress brake handle, and brake handle front end is embedded in the tooth of fluted disc, handle is carried out to position and fix, carry out the Kai Heguan of butterfly plate in regulation valve body.

The application's innovation is:

1, be fixed with fluorescence rubber chafing strip 7 at the upper surface interval of handle, this fluorescence rubber bar has two benefits, can increase on the one hand the abrasionproof performance of handle, on the one hand can be under the condition of insufficient light, play the effect of instruction and warning, prevent that valve is by malfunction, also can help valve switch staff to find rapidly the position of valve, very convenient practicality.

2, be shaped with direction fluorescence rubber arrow 8 at fluted disc upper surface, instruction valve-off or open the direction of valve, arranges according to actual needs, brings great convenience to user.

3, more stable for rubber ring installation, can be shaped with annular groove at the upper surface interval of handle again, fluorescence rubber bar is inlaid in annular groove, ensure the stability of rubber ring.

Claims

1. a handle butterfly valve, it is characterized in that: comprise handle, fluted disc, valve body, valve rod and butterfly plate, valve rod coaxially passes the valve neck on valve body top, the ring flange of valve neck upper end is coaxially fixedly mounted with fluted disc, between valve rod end and valve neck, rotate and be tightly connected, valve rod upper end is radially fixedly mounted with handle, turning handle actuate valve stem is rotated, butterfly plate is located in valve body, valve rod is fixedly connected with butterfly plate, handle bottom hinge dress brake handle, and brake handle front end is embedded in the tooth of fluted disc, handle is carried out to position and fix, be fixed with fluorescence rubber chafing strip at the upper surface interval of handle.
