Abstract
A manual three-way valve is a shunt three-way valve, comprising valve body, valve seat, valve shaft, valve plate and outer pipes. Isolating plate with a opening in the middle is welded in the middle of valve body. Both sides of valve plate have grooves and sealing rings used for soft sealing between valve plate and valve body or isolating plate. By-pass pipe and by-pass valve are fixed on the outside of valve body. The utility model has simple technology, compact structure, small size and weight, low cost and good seal ability without leakage.
Description
Technical field
The utility model relates to the valve in the mechanical engineering, is specifically related to the manual three-way valve that carries out system's shunting or switch in the water, steam, wet goods non-aggressive medium pipeline of a kind of being applicable to≤180 ℃.
Background technique
Gong Ying two-way electronic valve is cast structure in the market, and volume is big, and valve core sealed cover is metallic seal and heavy, and leak-down rate is big, poor sealing performance, and cracking pressure is big, and impulsive load is also big when closing, and easily clamping stagnation, fault are many, the cost height.
Summary of the invention
Technical problem to be solved in the utility model is: at above-mentioned the deficiencies in the prior art, and provide that a kind of manufacturing process is simple, in light weight, cost is lower, unlatching is laborsaving, reliable operation, nothing are leaked, the manual three-way valve of good seal performance.
The technical solution adopted in the utility model is: this manual three-way valve is made up of valve body, valve seat, valve shaft, valve plate, externally connected pipe, be welded with dividing plate in the middle of the valve body, open the heavy caliber tap hole in the middle of the dividing plate, the spool two sides is processed with sealing plane and seal groove, dress rubber seal in the groove, with valve body and dividing plate be the plane soft seal; The valve body outside is fixedly connected with bypass tube, and the bypass tube two ends are communicated with two outlets of valve body, and bypass valve is installed in the bypass tube.
The utility model welds the manufacturing process manufacturing owing to valve body adopts carbon steel tube, compact structure, and volume is little, and is in light weight; Again because spool is to be processed with sealing surface and ladder-type trough on the corrosion resistant plate two sides, the groove built-in ring, with valve body and dividing plate be the plane soft seal, sealing is reliable, leak-down rate and rate of fault are extremely low; Be welded with stainless steel separator in the utility model valve body, valve body is divided into two hydroeciums, two outer outlet ports of valve body have installed tubule footpath bypass tube and bypass valve additional, open release during high pressure in advance, the pressure that balance is imported and exported, thus valve plate can easily be opened.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, this manual three-way valve is the bypass type three-way valve, by valve body 4, valve body top board 5, valve seat 7,11, valve shaft 8, valve plate 17, bypass tube 14, bypass valve 15, externally connected pipe 1,2,12,13,28,29, valve bonnet 20 is formed, wherein 7 is upper valve base, 11 is lower valve base, 1,2 is inlet flange and inlet connection, 12,13 is warm water discharge connection and warm water outlet(discharge) flange, 28,29 are cooling water outlet adapter and cooling water outlet flange, valve body 4 adopts the carbon steel tube welding to make, the centre is welded with dividing plate 3, have the heavy caliber tap hole in the middle of the dividing plate 3, the valve body both sides are communicated, spool is the stainless steel weld assembly, the two sides is processed with sealing plane and ladder type seal groove, in dress ladder type rubber seal 18, valve shaft 8 and valve plate 17 are connected by connecting sleeve, valve shaft 8 end machining have arc surface, guaranteed that valve plate circumference when closing is evenly stressed, sealed more reliable.The other end of valve shaft 8 is a square head, be used for turning the switch valve plate, the lower end of valve plate 17 is welded with guide rod 21, with guide sleeve 22 Spielpassung in the cooling water outlet adapter 28, stablize the spool group and under the impact of medium, can not rock, valve can also can laterally be installed in vertical installation.Valve body 4 outsides are fixedly connected with tubule footpath bypass tube 14, and bypass tube 14 two ends connect two outlets 12,28 of valve body, and bypass valve 15 is installed in the bypass tube 14, and bypass valve 15 is general manually operated valve.When valve plate need be opened, at first open bypass hand valve 15, behind the pressure reduction of balance valve plate both sides, open the spool valve plate again, operating method is opposite when closing, and closes big valve plate earlier, closes bypass hand valve again, because the unlatching of valve plate is to carry out after the release, so can easily open.The valve bonnet 20 that is threaded is equipped with in the outside of valve shaft 8, the sealing surface of protection valve shaft, and the sealing of valve shaft 8 and valve body 4 realizes by a plurality of seal rings.Valve shaft 8 connects transmission at valve Cuo 7,11 internal threads, and the swivel nut on the valve Cuo is the tin bronze material of high hardness wear-resisting, can effectively prevent thread biting locking, and screw thread adopts built-in tight by the keyway edge, makes the unlatching space that simply can reduce installation again.Manual three-way valve is the bypass type structure, unloads safety cover during operation earlier, turns valve shaft with special spanner again, and valve plate is closed down outlet downwards during forward rotation, and fluid up side outlet is taken over outflow.During the backward rotation valve shaft, valve shaft drives valve plate and up closes upper outlet, and fluid down discharge connection flows out.When inlet pressure is too high, drive bypass valve earlier, open main valve again, under high pressure can easily open.The safety cover of valve shaft installs at ordinary times.The weld seam of valve body is all taked the welding method of welding by both sides or one side welding with back formation.
