Abstract
The utility model relates to a high-pressure water scale removal balance check valve, which belongs to the technical field of design and manufacture of check valves used for a high-pressure water scale removal system. The high-pressure water scale removal balance check valve consists of a valve cover and a valve body, and a soft sealing seat is arranged between an outer protection sleeve and an inner protection sleeve. The utility model is an important component of the high-pressure water scale removal system for rolling steel, is arranged at a pump outlet to be used as a check valve, and forms an outlet valve group with a hydraulic cone valve. When the check valve works, high-pressure water of the system enters a lower cavity of the valve through a water inlet for pushing a valve core to be lifted up, the water inlet and a water outlet are communicated, and the valve is opened. When the combined force of the pressure of media entering an upper cavity from the water outlet end through a through hole arranged at the lower end of the valve core and the reset spring force exceeds the thrust of the lower cavity and the corresponding frictional resistance, the valve core fast falls down, the conical surface of the valve core is completely pasted with the sealing seat, the water outlet is disconnected from the water inlet, and the valve is closed. The sealing seat of the utility model is made of soft materials, has high pressure-bearing performance, and is embedded at the joint part of the bottom part of a valve sleeve and a valve body through being clamped by the outer protection sleeve. When the valve is closed, impurity particles can be pressed into the valve once entering the sealing surface, the sealing effect is not influenced, the sealing conical surface of the valve core is also protected from being damaged, and the service life of the valve core is prolonged. The utility model solves the problems of the existing products.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of the safety check that high-pressure water descaling system uses.
Background technique
The safety check that present each iron and steel enterprise generally uses at the pump discharge place of the high-pressure water descaling system of rolled shape is the balance check valve, and constitutes the outlet valve group with the cone valve that surges.This balance check valve is made of gland, valve body, valve pocket, valve seat and Returnning spring and spool etc.Because valve port adopts the hard seal form of the conical surface, so the impurity particle in the system high pressure water causes damage to valve port easily, particularly leave very big gap between spool top and valve pocket, in case Returnning spring occurs tired cracked, tiny fragment very easily falls to the valve port place and spool is blocked, and valve can't be closed, but also can cause damage to the valve port conical surface, even removed the jam thing so later on, also very easily produce the not tight consequence of valve seal.The targeting part of spool bottom is a flap and shorter in addition, the situation that unbalance stress when impacted by high-pressure water flow, can occur, make that spool is not very nimbly and freely when moving up and down, especially easily cause the pass threshold sensitivity slow relatively, and these unfavorable factors bring bad influence all will for the normal operation of whole system.
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 balance check 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: be made of valve gap and valve body.Valve gap and valve body are fixed by bolt.At valve inner one valve pocket is arranged, a spool is arranged in valve pocket.In the outside of spool one annular seal groove is arranged.One seal ring is arranged in the annular seal groove.On the top of seal ring one guide ring is arranged.In the bottom of valve pocket one oversheath is arranged.There is an inner sheath oversheath inboard.Between oversheath and inner sheath, have the software sealing seat.On the top of valve pocket one upper spring seat is arranged.Suit Returnning spring on upper spring seat.One lower spring cup is arranged in spool.Suit one spring on the lower spring cup.Have water intake in valve body one side, have water outlet at opposite side.Water intake and water outlet are connected by body cavity.The utility model is the vitals in the rolled shape high-pressure water descaling system, is installed in pump discharge and constitutes the outlet valve group with the cone valve that surges as safety check usually.During work, system high pressure water enters into the valve cavity of resorption via water intake, and acts on the conical surface of spool lower end, and formed upwards thrust overcomes the spring force of Returnning spring and corresponding surface friction drag and promotes spool and lift, water intake and water outlet conducting, valve is opened.When by water outlet end by spool lower end through hole enter the pressure medium of epicoele and Returnning spring power make a concerted effort to surpass the thrust of cavity of resorption and corresponding surface friction drag the time, spool will fall fast, its conical surface and sealing seat are fitted fully, and water outlet and water intake disconnect, and valve is closed.The utility model has still adopted cone valve structure, has just cancelled valve seat, and valve pocket is designed to the structure that the fixing seal seat can be inlayed in the bottom.The sealing seat is a soft material system, has high-strength load performance, is embedded in the junction point of valve pocket bottom and valve body by inside and outside sheath clamping.When in a single day having impurity particle to enter sealing surface when closing valve, can be pressed in it, promptly not influence sealing effect, protect the sealing cone of spool not to be damaged again, prolong the working life of spool.Solved the problem that existing product exists.
