The high pressure steam stop valve comprises a keep plate, the valve body, a valve flap, a valve flap pressing sleeve, a valve stem, a filling pad, a flexible graphite packing, a valve deck, a straight pin, a filling pressing sleeve, an eyelet bolt, a stuffing ring, a hexagonal nut, a flap gasket, a bearing support, a thrust bearing and the like; the valve flap pressing sleeve and the valve flap are installed on the valve stem, and the valve flap pressing sleeve, the valve flap and the valve stem are installed on the valve body together; the keep plate is installed and fixed on the valve body; the filling pad, the flexible graphite packing and the filling pressing sleeve are arranged on the valve stem; the valve deck is arranged at the upper part of the valve body; the eyelet bolt is inserted in a hole at the left side of the valve deck and is connected with the hole through the straight pin; the stuffing ring penetrates the valve stem and the eyelet bolt from the upper part at the same time; the thrust bearing and the bearing support are installed on a valve-stem nut, and the thrust bearing, the bearing support and the valve-stem nut are arranged on the valve stem and the valve deck together; a handwheel is arranged at the top of the valve stem and is connected with the valve-stem nut; and an oil cup is installed at lower lateral part of the handwheel. The high pressure steam stop valve has advanced design and reasonable structure, prolongs the service life, leads the valve stem and the valve flap to be in tensioned state all the time, prevents a sealing pair from leakage, and has good sealability.
Description
Technical field: a kind of valve body that the utility model relates in the fields such as the limited boats and ships of working space, aviation adopts the high-pressure steam stop valve that divides body structure.
Background technique: because fields such as stop valve extensive use oil, chemical industry, metallurgy, electric power, fire-fighting, pharmacy, food, boats and ships.Therefore, China industrial pipeline system is a large amount of at present uses by the class valve.Stop valve is a kind of closed circuit valve that switches on or off pipeline fully, and it generally is made up of major parts such as actuator (handwheel), valve rod, valve body, valve gap, flap (closure member) and filler devices.Handwheel links to each other with valve rod, and passes to flap by valve rod, makes flap along the to-and-fro motion of valve seat axial direction, thereby pipeline is switched on or off.But, traditional design by the class valve, make valve rod and flap when valve closing, be in pressured state all the time, the pressure direction that promptly be situated between to end is subjected to force direction opposite with valve rod and flap, if sealing surface has damage slightly or because accident when causing pretightening force to reduce, its medium will leak from sealing vice division chief under the effect of self pressure, and will be particularly serious when medium is high pressure steam.
Along with the sustainable development of Chinese national economy, China's energy industry has been proposed very urgent requirement, the angle of collateral security energy security is set out, and action in the state of accident is a big technical problem of being badly in need of solution in related domain promptly and accurately.Will cause the generation of the significant wastage and the serious accident of the energy like this.Therefore the high-pressure steam stop valve of developing a kind of valve body employing branch body structure is a new problem anxious to be solved always.
The model utility content: the purpose of this utility model provide a kind of valve body adopt divide body structure, have installation, maintenance convenient, dwindled small product size, reduced product weight, be applicable to that the valve body in fields such as the limited boats and ships of working space, aviation adopts the high-pressure steam stop valve that divides body structure.
The purpose of this utility model is achieved in that valve body adopts the high-pressure steam stop valve that divides body structure, whole device is by pressing plate, valve body, flap, the flap gland, valve rod, Packing seat, flexible graphite stuffing, valve gap, straight pin, the filler gland, swing bolt, Gland, hexagon nut, plain washer, bearing support, thrust-bearing, Stem Mut, lubricating cup, handwheel is formed, flap gland and flap are being installed on the valve rod and are being installed in it on valve body together, pressing plate and fixing is installed on valve body, Packing seat is installed on valve rod, flexible graphite stuffing and filler gland, valve gap is installed in valve body top, swing bolt inserted in the valve gap left hole and with straight pin connect, Gland is penetrated valve rod and swing bolt simultaneously from top, plain washer is installed on swing bolt and is tightened up with hexagon nut, be installed in together on valve rod and the valve gap at installed thrust bearing and bearing support on the Stem Mut and with it, handwheel is installed in the top of valve rod and is connected, lubricating cup is installed in the side lower part of handwheel with Stem Mut; The center of valve body is a through hole, and valve body adopts and divides the valve body of body structure to be connected with pressing plate.
Main points of the present utility model are the structural type and the working principle of its product.Its working principle is: the sealing surface of high-pressure steam stop valve flap is below valve body sealing surface, when valve closing, the pressure direction of medium is subjected to force direction identical with valve rod and flap, make the sealing pair of valve be in the optimal seal state all the time, not only guarantee reliable sealing performance, improved the working life of valve simultaneously.Valve body adopts a minute body structure, has the installation, maintenance convenience, has dwindled small product size, reduces product weight, is applicable to fields such as the limited boats and ships of working space, aviation.
The high-pressure steam stop valve of valve body employing branch body structure compared with prior art, have advanced design, rational in infrastructure, improve working life, make valve rod and flap be in tension state all the time, prevent to seal vice division chief and leak, have advantages such as good seal performance, will be widely used in the fields such as the limited boats and ships of working space, aviation.
Description of drawings: concrete structure of the present utility model is provided by following example and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model valve body.
