Abstract

A stop valve with pilot manual ball valve comprises a main valve body (1), an inlet (2), an outlet (15), a valve core (13) and a valve core bottom hole (14), wherein, the periphery of the valve core (13) is provided with a guide sleeve (5) and a sealing ring (6); an upper clapboard (3) and a lower clapboard (18) are arranged inside the main valve body (1); the upper part of the main valve body (1) is provided with a cover plate (7); an upper chamber (10), an outer chamber (4) and an inner chamber (12) are respectively enclosed among the main valve body (1) together with the clapboards (3, 18), the valve core (13) and the cover plate (7); a central part between the valve core (13) and the cover plate (7) is provided with a spring (9); a stainless steel manual ball valve (8) is arranged on a flow guiding pipe (22) of the upper chamber (10) and the outer chamber of the main valve body (1). The stop valve can be widely applied to valves only needing direct manual operation in the industries such as oilfield, chemical engineering, beverage, medicine, tap water and natural gas, is especially suitable to be used as a fire valve, and has the advantages of flexible and laborsaving operation, high precision, fast motion, no corrosion, simple installation, long life-span, etc.

Description

The stop valve of band guiding manual ball valve

Technical field

The utility model relates to a kind of stop valve, particularly has the stop valve of the pilot valve of manual control ball valve, is suitable for doing fire valve especially.

Background technique

The fire-fighting open and close of stop valve, generally adopting the mechanical type handwheel to rotate at present realizes, these valves, indoor installation on the wall, outdoor mounted is in ad hoc shallow well, pull all inconvenience with hand is stubborn with spanner, mechanical handwheel rotates the open and close to stop valve, slow in one's movements, easy-to-rust, be difficult to open, operation inconvenience, when fire fighting finishes, bleed off the surplus water rate power of fire-extinguisher water hose, labor intensity is big, the be far from suitable needs of the fire-fighting fire fighting of racing against time, time-delay thereby damnous phenomenon are not rarely seen thus.

Through market survey and retrieval, find to adopt manual ball valve to control the material object and the related data of the open and close of the stop valve that fire-fighting uses as pilot valve as yet.

From the consideration that is close of relevant technologies such as simple installation and low cost, the utility model rotates the control stop valve with the mechanical type handwheel and opens and closes the contrast material of making prior art.

The model utility content

At the above-mentioned deficiency of prior art, the purpose of this utility model be design a kind of not corrosion, easily open and close, action is fast, sensitivity is good, the stop valve of band guiding manual ball valve.

The purpose of this utility model can realize by following measure:

It contains main valve body, import, outlet, last through-flow chamber, following through-flow chamber, spool, upper clapboard and lower clapboard, upper part of the main valve body has cover plate, be with chamber, mistress, inner room between dividing plate in main valve body wall and the main valve body, spool, the cover plate, spool is class alms bowl shape, the spool bottom outlet is arranged at the spool bottom, the spool periphery has guide sleeve, the last inwall of guide sleeve has seal ring, the central part of spool and cover plate is fixed with spring, the last chamber and the mistress of main valve body have honeycomb duct to be communicated with, and the stainless steel manual ball valve is installed on the honeycomb duct.

Base plate is arranged at the main valve body bottom, and base plate has pollutant exhaust hole, and this hole is equipped with sealing nut; The aperture of spool bottom outlet is less than the internal diameter of honeycomb duct; Pressure ring is arranged at spool top; Outer chamber walls has the dewatering orifice.

The beneficial effects of the utility model are: not corrosion, easily open and close, action is fast, bleed off surplus water in the water band convenient, simple, long service life be installed.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model scheme of installation.

Embodiment

The utility model is further specified below in conjunction with embodiment and with reference to accompanying drawing: the utility model contrasts the stop valve of the general mechanical type handwheel rotation of present fire valve and has done as above to improve: cancelled handwheel, valve rod, interior lifting nut, change guide pad and guiding groove into guide sleeve 5, change the cheese spool into class alms bowl shape spool 13, and open spool bore 14 in the bottom, the former valve rod hole of loam cake transformed into be pod apertures, because of increasing pressure ring 11, seal ring 6 and change spool 13 into class alms bowl shape, through-flow chamber is divided into goes up chamber 10, the mistress 4, inner room 12, be equipped with honeycomb duct 22 and stainless steel manual ball valve 8 in last chamber and mistress's outside, central part at the

cover plate

7 and 13 ends of spool adds spring 9, spool 13 tops add the pressure ring 11 that compresses seal ring 6, have the dewatering orifice on mistress 4 wall
