Abstract
A stop valve comprises a valve body, a valve seat mounted inside the valve body, a valve disc mounted inside the valve seat, two guide rods mounted at the lower end of the valve disc, a valve rod provided with a boss at the lower end part, a valve disc cover connected onto the valve disc through threads, a check washer mounted between the valve disc and the valve disc cover, a valve deck mounted on the upper end face of the valve body through a fastening bolt, packing rings mounted between the valve body and the valve deck, packing mounted between the valve rod and the inner part of the valve deck, a packing gland mounted on the valve deck through a bolt, a valve rod nut of which the internal thread and the external thread are respectively connected with the valve rod and the valve deck, a set screw used for fastening the valve rod nut, and a rotary hand wheel mounted at the top end of the valve rod. The stop valve is low in friction force, wearable, small in opening height, easy to manufacture, convenient to use, simple to mount and dismount, easy to maintain, high in guide precision, tight in sealing, and long in service life, so that the stop valve can be widely applied to a pipeline system taking water as an industrial medium.
Description
Technical field the present invention relates to a kind of stop valve, can be widely used in pipe-line system that industrial media is water.
The stop valve that background technique is traditional, its valve disc Center an axis of guide, guiding accuracy is poor, the tightness of valve is also poor, life of valve is short.
Summary of the invention the object of the present invention is to provide that a kind of frictional force is little, wear-resisting, Lift is little, easy to manufacture, easy to use, installing/dismounting simple, maintenance easily, guiding accuracy is high, sealing is tight, the stop valve of long service life.
In order to achieve the above object, stop valve of the present invention, comprise valve body, be arranged on the valve seat in valve body, be arranged on the valve disc in valve seat, be arranged on two guide rods of valve disc lower end, underpart is with the valve rod of boss, be arranged on stem lower portion and be threaded connection the valve disc lid on valve disc, be arranged on the lock washer between valve disc and valve disc lid, be arranged on valve rod and be arranged on the valve gap of valve body upper-end surface by clamping bolt, be arranged on the packing ring between valve body and valve gap, be arranged on the filler between valve rod and valve gap inside, being positioned at filler top is arranged on valve rod and by bolt and is installed to the Gland on valve gap, internal thread, outside thread respectively with valve rod, the Stem Mut that valve gap connects, at the Cock screw for fastening Stem Mut of valve gap and the installation of Stem Mut screw thread junction, the rotation handwheel of installing in valve stem tip.
Stop valve of the present invention, said valve seat, its material is tin bronze.
Stop valve of the present invention, said valve disc, comprises valve disc ectosome, is threaded connection the valve disc endosome that is arranged on ectosome inside.
Stop valve of the present invention, said valve disc ectosome, its material is tin bronze.
Stop valve of the present invention, its working principle is: the valve disc interplanting open-shut device driving with valve disc also moves along valve seat axis, to realize switching motion.The handwheel of rotation valve rod top, the pressure that relies on the rotation of valve rod to produce valve disc, fits tightly valve disc cover sealing surface and sealing surface of seat, and valve closing, stops medium circulation.Rotate counterclockwise, open valve, medium circulation.
Stop valve of the present invention, switch sealing surface valve seat, valve disc ectosome are tin bronze material, wear-resisting, anti-corrosion, for high load, medium Sliding velocity.
Stop valve of the present invention, due in switching process between sealing surface frictional force little, wear-resisting, Lift is little, easy to manufacture, easy to use, employing is threaded, installing/dismounting is simple, maintenance easily.
Stop valve of the present invention, is mainly used in blocking fluid, and the not high occasion of adjusting performance requirement also can be used for adjusting flow.Be not only applicable to mesolow, and be applicable to high pressure.
Stop valve of the present invention, is two by one, traditional valve disc center axis of guide design update, i.e. easy processing has improved again the validity of the guiding of valve disc lifting, makes the sealing of valve tight, long service life simultaneously.
In sum, stop valve of the present invention, frictional force is little, wear-resisting, and Lift is little, easy to manufacture, easy to use, and installing/dismounting is simple, and easily, guiding accuracy is high in maintenance, and sealing is tight, long service life.
Brief description of the drawings is further described the present invention below in conjunction with accompanying drawing and embodiment.
Fig. 1 is structural representation of the present invention.
Embodiment is in Fig. 1, stop valve of the present invention, comprise valve body 1, be arranged on the valve seat 2 in valve body, be arranged on the valve disc 3 in valve seat, be arranged on two guide rods 4 of valve disc lower end, underpart is with the valve rod 5 of boss, be arranged on stem lower portion and be threaded connection the valve disc lid 6 on valve disc, be arranged on the lock washer 7 between valve disc and valve disc lid, be arranged on valve rod and be arranged on the valve gap 8 of valve body upper-end surface by clamping bolt 15, be arranged on the packing ring 9 between valve body and valve gap, be arranged on the filler 10 between valve rod and valve gap inside, being positioned at filler top is arranged on valve rod and by bolt 16 and is installed to the Gland 11 on valve gap, internal thread, outside thread respectively with valve rod, the Stem Mut 12 that valve gap connects, at the Cock screw 13 for fastening Stem Mut of valve gap and the installation of Stem Mut screw thread junction, the rotation handwheel 14 of installing in valve stem tip.
Stop valve of the present invention, said valve seat, its material is tin bronze.
Stop valve of the present invention, said valve disc, comprises valve disc ectosome 3-1, is threaded connection the valve disc endosome 3-2 that is arranged on ectosome inside.
Stop valve of the present invention, said valve disc ectosome, its material is tin bronze.
