Abstract

The invention discloses a stop valve with a pilot ball valve. The stop valve comprises a valve body, a bonnet and a valve clack. The bonnet is arranged on the valve body, the valve clack is arranged in the valve body, a guide sleeve is arranged between the valve clack and the valve body, a ball valve is arranged on the bonnet, a spring is arranged between the bonnet and the valve clack, and a diversion tube is connected between the ball valve and the valve body. The stop valve has the advantages of being capable of achieving basic functions of common stop valves, flexible and effort-saving to operate, high in accuracy, quick in action, anti-corrosion, simple to mount, long in service life, convenient to maintain and the like.

Description

With the stop valve of guide's ball valve
Technical field
The present invention relates to stop valve design field, be specifically related to a kind of stop valve with guide's ball valve.
Background technique
Stop valve domestic at present adopts handwheel or Electric actuator to drive mostly, when adopting handwheel drive stop valve to open or close, slow in one's movements, labor intensity is large, automaticity is low, is unfavorable for the integrating control of valve, and easily causes the security incident because misoperation causes, when adopting common electric device to open and close stop valve, mechanism is huge, and energy consumption is large, and cost is high, time on the pipeline being applied in oil transportation or chemical industry flammable and explosive fluid, inconvenience maintenance and there is accident potential.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of stop valve with guide's ball valve is provided.
The technological scheme that the present invention is adopted for achieving the above object is: the stop valve of band guide ball valve, comprise valve body, valve gap, flap, described valve gap is arranged on valve body, described flap is arranged in valve body, between described flap and valve body, guide sleeve is installed, described valve gap is provided with ball valve, between described valve gap and flap, spring is installed, between described ball valve and valve body, be connected with honeycomb duct.
Between described guide sleeve and flap, seal ring is installed.
Feature of the present invention is: the fundamental function that can reach common stop valve, have that flexible operation is laborsaving, precision is high, action soon, not corrosion, simple, long service life and the advantage such as easy to maintenance are installed.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention;
Fig. 2 is side view of the present invention.
Wherein: 1, valve body 2, guide sleeve 3, seal ring 4, valve gap 5 ball valve 6 spring 7, flap 8, honeycomb duct.
Embodiment
As shown in Figure 1, 2, the present invention includes valve body 1, valve gap 4, flap 7, described valve gap 4 is arranged on valve body 1, described flap 7 is arranged in valve body 1, between described flap 7 and valve body 1, guide sleeve 2 is installed, between described guide sleeve 2 and flap 7, seal ring 3 is installed, described valve gap 1 is provided with ball valve 5, between described valve gap 1 and flap 7, spring 6 is installed, between described ball valve 5 and valve body 1, is connected with honeycomb duct 8.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technological scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
