Abstract
The utility model discloses a pneumatic and hydraulic cone valve for high-pressure water descaling, belonging to the technical field of design and manufacture of the hydraulic cone valve used for a high-pressure water descaling system. A main valve consists of a valve body and a valve cover, wherein a shuttle valve is arranged at one side of the main valve; and a throttle stop valve is arranged at the other side of the main valve. A two-position three-way pneumatic reversing valve is arranged on the throttle stop valve. A soft sealing seat is arranged between inner and outer sheathes. The cone valve is an important part in the high-pressure water descaling system for rolling steel and is arranged at the outlet end of a pump to form an outlet valve group with a balance check valve. A valve rod is rotated to limit the opening position of a valve core, so as to adjust the medium flow of a water outlet. The high-pressure water of the system is utilized as a power source to realize the on/off of the valve. The sealing seat is made of soft sealing materials, so that impurity particles are pressed in a matched conical surface of the sealing seat and the valve core when the valve is off, the sealing conical surface of the valve core is protected, and the water purity requirement is greatly reduced, therefore, the service life of the valve is prolonged. As a hydraulic oil station is removed, the overall structure of the valve is compact, the processing and manufacturing difficulty is greatly reduced, and the installation and centralized maintenance are convenient.
Description
Technical field
The utility model belongs to design and the manufacturing technology field of high-pressure water descaling system with the cone valve that surges.
Background technique
What each steel mill generally used in the high-pressure water descaling system outlet valve group of rolled shape at present is the cone valve that surges, and the hydraulic control mode that is adopted need dispose hydraulic oil unit power source is provided.The cone valve that surges is made of valve body, gland, gland nut and valve cup, spool and valve rod.Because spool is longer, need run through whole valve body from top to bottom, all increased difficulty for processing and assembling.What adopt between spool and valve cup simultaneously is hard seal form, makes the processing of sealing cone also have certain degree of difficulty, and also higher to the degree of purity requirement of high pressure water when using.Because seal point is many, cause the place of easy leakage to increase in addition, this has increased many difficulty all for the manufacturing and working service thereupon.Therefore except manufacture cost was higher, it was safeguarded and also has certain difficulty.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of spool that can effectively prevent by the high-pressure water descaling gas control cone valve of foreign particles mill card.To solve the problem that existing product exists.
Structure of the present utility model is as shown in drawings: main valve is made up of valve body and valve gap.Valve body connects by bolt mutually with valve gap.On a side of main valve, a shuttle valve is arranged.One throttling stop valve is arranged on the main valve opposite side.On throttling stop valve, have the two-position three way air operated reversing valve.One valve cup is arranged in valve body.There is the inboard that one inner sheath is arranged in the bottom of valve cup.Have oversheath in the inner sheath outside.Between interior oversheath, have the soft seal seat.Have the conical surface on the soft seal seat.One spool is arranged in the valve cup.The bottom of spool is taper.There is a closure gasket groove outside, middle part at spool, and a seal ring is arranged in the annular groove.On seal ring top one guide ring is arranged.On the top of spool one gland is arranged, at gland bottom suit one spring.On spool, have a valve rod.Have threaded bushing in the valve rod outside.One handwheel 1 is arranged at the top of valve gap.One guide pin bushing is arranged between gland and valve rod.One V-arrangement combined seal ring is arranged in the guide pin bushing.Bottom at valve body has outlet pipe.Side at valve body has water intake, has water outlet at the opposite side of valve body.The utility model is the vitals in the rolled shape high-pressure water descaling system, be installed on the delivery side of pump end and form the outlet valve group with the balance check valve, during work, high-pressure medium is entered by water intake through the overbalance check valve, form thrust upwards and overcome the spring force of spring and corresponding surface friction drag and promote spool and lift on the spool ring surface, valve is opened.Rotation valve rod can limit the enable possition of spool, and adjusts the rate-of flow at the mouth of a river with this.The utility model has adopted a kind of brand-new composite structure form, no longer need to dispose hydraulic oil unit as power source, but adopted self contained hydraulic control mode, promptly by the pilot-actuated valve of configuration, the high pressure water that makes full use of system self is realized the switch motion of valve as power source.Though sealing valve port has still adopted the cone valve structure form simultaneously; but what sealing seat used is soft sealing material; impurity particle in the system high pressure water can be pressed into when valve is closed in sealing seat and the conical surface that spool cooperates; greatly protected the sealing cone of spool; degree of purity to system high pressure water requires also to reduce greatly, thus the working life of having improved valve.The utility model makes the overall structure of valve become compact more owing to removed hydraulic oil unit, and the manufacturing difficulty reduces significantly, thereby greatly reduces the cost of raw material and manufacture cost.Installation and Centralized maintenance are all very convenient.
