Compared with the existing high pressure valve, the utility model has the advantages that the pipe wall of the valve flap (2) is provided with a plurality of through hole (17); both sides of the valve flap (2) are caused to be simultaneously subjected to pressure of the water, and thus, the force subjected by both of the two sides of the valve flap (2) can be mutually counteracted, and the desired force for opening and closing is small. The novel ladder-shaped sealing ring (4) is adopted; working pressure is high; the service life is long, and dropping, overflowing, seeping, and leaking phenomena can not be provided. The utility model has the advantages of simple structure, small size, light weight, small opening and closing force, and convenient installation.
Description
The utility model is a kind of novel plunger-type minute-pressure difference high pressure right angle valve, is used for water delivery, urban pipe network, industries such as oil, chemical industry and long distance line.
At present big, the complex structure of existing all kinds of high pressure valve volumes, heaviness are put for the shop of pipeline and have been brought very big inconvenience.The principle of existing its sealing of high pressure valve is substantially as Fig. 5, on flap or valve body, be embedded with sealing material, utilize the tapering of flap and valve body to come the crush seal material, this structure, sealing material is squeezed, be out of shape very big, so the life-span is very low, so existing high pressure valve is often with in various degree the phenomenon of dripping, ooze, leaking; Be to realize its sealing effect when closing by very big extruding force, and with very big counterpressure, so in the process of opening and closing, time-consuming, effort.
The utility model is at the shortcoming and defect of above prior art, provide a kind of simple in structure, switch convenient, the effective high pressure valve of pressurize.
Plunger type of the present utility model right angle high pressure valve mainly comprises valve body (1), is positioned at the flap (2) of valve body, is installed in the axle sleeve (8) at valve body upper port place and passes the axle sleeve center hole and the top is equipped with the screw mandrel that is positioned at the valve body center (7) of handle, it is characterized in that: flap (2) is straight tube-like, and the inner tubal wall on flap (2) top is threaded with the outer tube wall of screw mandrel (7) bottom; Have water inlet (16) in the bottom of flap (2), and on the tube wall on flap (2) top, be provided with several through holes (17); Between the outer tube wall of valve body inner tubal wall and flap, be provided with two groups of seal rings (4) up and down, every group has more than one seal ring, seal ring (4) adopts T type or ladder-type seal ring all can, if adopt T its seal groove of RunddichtringO (18) to be located on the flap pipe outer wall, the position of seal ring this moment (4) is: when the valve complete opening, two groups of seal rings (4) are positioned at the into upside of water arm water inlet (15), when valve closing, two groups of seal rings (4) are positioned at the into both sides of water arm water inlet (15); If adopt the ladder-type seal ring, its seal groove (18) is located on the valve body, and seal ring this moment (4) is positioned at into water arm water outlet (15) both sides; The pin or the key (3) that play the guiding role are installed on valve body, on the outer tube wall of flap bottom, are provided with a guiding groove (19) accordingly and cooperate with it.
The utility model compared with prior art has following advantage: because be provided with through hole (17) with the water outlet fluid communication on flap (2), make the both sides of flap (2) be subjected to the pressure of water simultaneously, so the power that flap (2) both sides are subjected to is cancelled out each other, required unlatching or the power of closing are very little, and it is rapidly convenient to open or close; The pressure height that can bear.The utility model adopts novel T type or ladder-type seal ring (4), has reached the satisfactory sealing effect, under high pressure (65MP), the long-time interior phenomenon of dripping, emitting, ooze, leaking of not having.Advantages such as this valve also has reliable operation in addition, volume is little, simple in structure, cost is low, in light weight, long service life, installation and maintenance are extremely convenient.
