Abstract
The utility model relates to a two-purpose stop valve, which belongs to a pipe line valve and is suitable for a pressure machine with the working medium of flow fluid. The utility model has the main structure that a valve core seat (5) and a valve rod (7) sheathed with a guide sleeve (6) are arranged in a valve body (3) with a liquid inlet (1) and a liquid outlet (2); a flange gland (8) and a screw seat (9) are threaded out of the upper end of the valve rod (7) and connected with a handle (10); a lower valve seat (11) and an upper valve seat (12) are arranged on a liquid outlet of a liquid inlet (1), and the lower valve seat (11) and the upper valve seat (12) are arranged at the lower end of the flange gland (8) respectively. The utility model is characterized in that the valve body (3) is provided with a liquid return hole (13) and the valve core seat (5) is provided with an upper valve core (14); the circumference of the guide sleeve (6) is provided with a plurality of liquid return grooves (15); a hole (16) which is cut on the flange gland (8) is communicated with a reflux hole (13).
Description
The utility model relates to a kind of pipeline valve, and specifically a kind of to be used at working medium be the valve that uses on the press of fluid.
When in pressure mechanism, adopting manually-operated gate control fluid, need two stop valves to control feed liquor and fluid respectively usually, make maintenance and operation inconvenience especially, to make the valve stem seal place very easily leak because valve is in the high pressure.Need constantly to change sealing material, influence the life-span and the use of valve.
The purpose of this utility model provides a kind of maintenance and easy to use, and the function of holding two valves is in the dual-purpose stop valve of the turnover of one.
The utility model (being embodiment) is achieved in that valve core case 5 that has lower valve core 4 and the valve rod 7 that is with guide pin bushing 6 is housed in the valve body 3 that has inlet opening 1 and liquid outlet opening 2, the upper end of valve rod 7 passes flange gland 8 and is connected with handle 10 with nut seat 9, the lower end of the liquid outlet of inlet opening 1 and flange gland 8 is equipped with lower valve base 11 and upper valve base 12 respectively, have hole for back flow 13 on the said valve body 3, upper valve core 14 is housed on the valve core case 5, the periphery of guide pin bushing 6 has several liquid return troughs 15, flange gland 8 has hole 16 that communicates with hole for back flow 13 and the groove 17 that communicates with hole 16, and above-mentioned valve rod 7 is a double thread screw.
Rotate counterclockwise handle 10 during use, upper valve core 14 is contacted with upper valve base 12 sealings, liquid enters press from inlet opening 1 inflow and through lower valve base 11 and liquid outlet opening 2; When clockwise rotating handle 10, lower valve core 4 is contacted with lower valve base 11 sealings, liquid enters hole for back flow 13 from the pressure mechanism outflow and through liquid outlet opening 2 and liquid return trough 15, finally flows out valve body 3.
The utility model both can be manual, also can be pneumatic or electronic, have rational in infrastructure, maintenance and easy to use, and the advantage of a valve dual-purpose is suitable for using in the various high, medium and low pressure scopes, has solved the problem that easily leak at the medium-term and long-term valve stem seal place that exists of high pressure valve.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is an A-A face sectional view.
Accompanying drawing 3 is a B-B face sectional view.
