Abstract
The utility model relates to a hydraulic rubber-lining stop valve with abrasion resistance, and belongs to the universal machinery. The utility model is composed of a valve body, a bottom cap, a big valve clack, a small valve clack, a valve rod, a hydraulic cylinder, a piston, etc., wherein, the interior of the valve body is lined with the abrasion resistance rubber. The utility model has the advantages of advanced and reasonable structure, superior performance, safe utilization, abrasion resistance and long service life, and is suitable for the industries of metallurgy mines, power plants, chemical industry, coal mines, etc.
Description
The utility model is a kind of rubber lined globe valve that surges, and belongs to universal machine.
At present, stop valve is owing to be subjected to structural limitations, and its valve rod axial force is big, and general stop valve mostly is only limited to small-bore, and present metallurgical mine, industries such as power plant, chemical industry, colliery are badly in need of heavy caliber, automatic stop valve.
The purpose of this utility model provides a kind of heavy caliber, automatic stop valve.
The utility model is realized with following technological scheme: little valve distinguishes that 7 are contained in the head of valve rod 2, little valve distinguishes that 7 are contained in big valve and distinguish in 8, big valve distinguishes that the sealing surface of 8 primary sealing areas and valve body 6 forms sealing pair, and little valve distinguishes that 7 sealing surface distinguishes 8 secondary sealing area composition sealing pair with big valve, with valve rod 2, little valve distinguishes 7, big valve distinguishes that 8 pack in the valve body 6, and with the Sealing 4 bottom 5 sealed letter places of packing into, bottom 5 cooperates with valve body 6, bottom 5 promptly is the valve gap of stop valve, is again the bottom of oil hydraulic cylinder 1.Piston 3 is contained in the oil hydraulic cylinder 1 of packing on the valve rod 2 and is mated.Sealing cover and valve rod 2 place's seal arrangements are equipped with in oil hydraulic cylinder 1 top, owing to adopt big or small two groups of valves to distinguish sealing configuration.Can reduce the switching power of valve itself greatly, can correspondingly reduce the diameter of oil hydraulic cylinder, reduce the suffered axial force of valve rod.Little valve is distinguished and can be distinguished middle slip at big valve.Oil hydraulic cylinder makes the piston action in the oil hydraulic cylinder by outside four-way change-over valve, drives little valve earlier and distinguishes keying, when reaching certain position, drives big valve again and distinguishes keying, makes the medium circulation or ends.The pressure of oil hydraulic cylinder derives from shaft gland of sand pumps water.Body cavity is lined with abrasive rubber.
It is rationally advanced to the utlity model has structure, superior performance, and safe and reliable, wear-resistant, the life-span is long.
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is that the utility model master looks sectional view.
Fig. 1 is the utility model specific embodiment.Little valve distinguishes that 7 are contained in the head of valve rod 2, little valve distinguishes that 7 are contained in big valve and distinguish in 8, big valve distinguishes that 8 primary sealing area forms sealing pair with the sealing surface of valve body 6, and little valve distinguishes that 7 sealing surface distinguishes 8 secondary sealing area composition sealing pair with big valve, with valve rod 2, little valve distinguishes 7, big valve distinguishes that 8 pack in the valve body 6, and with the Sealing 4 bottom 5 sealed letter places of packing into, bottom 5 cooperates with valve body 6, fastening by link, bottom 5 is parts of valve gap and the comprehensive one of oil hydraulic cylinder bottom.Piston 3 is contained on the valve rod 2, and the oil hydraulic cylinder 1 of packing into is mated.Sealing cover and valve rod 2 place's seal arrangements are equipped with in oil hydraulic cylinder 1 top.
