Detailed description of the invention
Below in conjunction with accompanying drawing 1 and accompanying drawing 2, further illustrate principle of the present utility model and structure by embodiment.A kind of single connection-rod linkage dual-valve body dosing pump, its concrete structure consists of: cylinder 1 is fixed on cylinder rack 2, is connected with dosing pump cylinder rack 7 and interlock plate 4 respectively by guide rod 5, cylinder plunger 3.The upper end of A plunger 20 and B plunger 8 is separately fixed at the two ends of interlock plate 4 and is assembled into one, and plunger lower end is positioned at cylinder body 6, and cylinder body 6 is fixed on cylinder rack 7.Two plungers are equipped with seal combination with the junction of cylinder body, seal 21 including upper cover 23, sealing group ring 22 and scraper, and the left and right sides at A, B cylinder body is respectively equipped with charging aperture 9, is connected with A cylinder sleeve 19 and B cylinder sleeve 10 between cylinder body and plunger respectively.A, it is connected with A check valve body 16 and B check valve body 14 respectively bottom B cylinder sleeve, in B check valve body 14, B check valve assembly 11 is connected bottom B cylinder sleeve 10, in the bottom of core assembly equipped with spring 12, in A check valve body 16, A valve seat 18 is connected bottom A cylinder sleeve 19, and A spool 17 is connected on A valve seat 18, is also equipped with spring bottom spool.A, B two the left and right sides of check valve body be respectively equipped with discharging opening 13, be additionally provided with drain hole 15 at A, B seat bottom portion.
A, B two plunger be assembled into one in parallel by interlock plate, can move under the effect of interlock plate simultaneously, and control at sustained height the most simultaneously.Two kinds of fluids enter in A, B cylinder by the charging aperture of side of cylinder block respectively, can regulate the proportioning of two kinds of fluids according to the diameter ratio of two plungers and cylinder sleeve.
Plunger and cylinder body junction equipped with seal combination in, upper cover, sealing group ring and scraper seal compact siro spinning technology successively, when sealing group ring and scraper sealing being caused mild wear due to the upper and lower motion of plunger, the height of upper cover can be regulated, again realize the sealing of dosing pump, improve anti-wear performance and the service life of equipment.When described scraper seals and sealing group ring can effectively prevent spool from rising, solution remains in core surface, reduces the extent of corrosion of spool face.Meanwhile, seal combination has certain length, has good guide effect to plunger.A, B two the junction of cylinder sleeve and check valve body be equipped with O RunddichtringO, be also beneficial to improve further the sealing property of dosing pump.
It is respectively arranged with spring, closed mode of can being rebounded by spool after plunger completes a quantitative revolution in the bottom of A, B core assembly.
The drain hole being provided with at A, B seat bottom portion can be used for experiment sampling checking A, B two the metering precision of Sets of Measurement pump it can also be used to the air in emptying dosing pump or unnecessary feed liquid.
During metering distribution and pumping metering, in two kinds of liquid are injected separately into A, B cylinder by the charging aperture of cylinder body both sides after, regulate switching cylinder, A, B two plunger pass through interlock plate and start to move downward under pneumatic action.Now, fluid is made spool move down by the pressure that plunger moves downward, and is formed between valve seat and keep a fixed gap.Fluid is flowed out from discharging opening by the space of spool with valve seat.Time bottom plunger motion to cylinder sleeve, again regulating switching cylinder, make plunger start to move upward, the power that now spool is moved downward by fluid and plunger disappears, and spool is bounce back into initial closed mode by spring.In the uphill process of plunger, fluid continues through charging aperture and has respectively entered in A, B cylinder, and after fluid injection terminates, regulation switching cylinder makes plunger start to move downward, and starts new round metering distribution and pumping quantitative revolution.
