Abstract
The invention relates to an improved high-precision crystallization-preventing ceramic filling pump which comprises a ceramic core body. A cylinder body is in interference fit with one end of the ceramic core body. A liquid inlet and a liquid outlet are formed in the circumference of the cylinder body, are symmetrical about the cylinder body and are communicated with an inner cavity of the ceramic core body. A liquid inlet nozzle and a liquid outlet nozzle are installed in the liquid inlet and the liquid outlet respectively. A rotating valve is inserted into the inner cavity in the end, with the cylinder body, of the ceramic core body. The end of the rotating valve is provided with a U-shaped valve bush. A liquid through hole is formed in the external circle of the rotating valve. A metering rod is inserted into the other end of the ceramic core body. Both the ceramic core body and the metering rod are made of ceramic materials. A water inlet and a water outlet are formed in the upper portion and the lower portion of the external circle of the ceramic core body respectively. A water guide groove is formed in the inner cavity of the ceramic core body. The water inlet and the water outlet are communicated with the upper end and the lower end of the water guide groove respectively. A plurality of grooves are evenly formed in the external circle of the metering rod. The improved high-precision crystallization-preventing ceramic filling pump is resistant to corrosion and high temperature, long in service life and stable in performance.
Description
Technical field
The present invention relates to pump technical field, particularly relate to a kind of accurate filling pump be made up of ceramic material.
Background technique
The Application comparison of existing medicine and chemical industry plunger pump is extensive, mostly present plunger pump is metal pump, the hardness of metal pump is low, wear-resisting, poor corrosion resistance, and non-refractory, because metal pump exists above-mentioned deficiency, cause its working life short, need regularly to change, cause cost of production higher.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, provide modified model high-accuracy crystallization-preventive ceramic filling pump, its structure is simple, corrosion-resistant, high temperature resistant, the life-span is long, stable performance.
The technical solution adopted in the present invention is as follows:
The high-accuracy crystallization-preventive ceramic filling pump of modified model, comprise ceramic core body, one end interference fit cylinder body of pottery core body, the circumference of cylinder body is with liquid entering hole and liquid outlet, liquid entering hole and liquid outlet are symmetrical and communicate with the inner chamber of ceramic core body about cylinder body, install liquid inlet port and liquid outlet respectively in liquid entering hole and liquid outlet; Pottery core body is inserted with rotating valve with in the inner chamber of cylinder body one end, and the end of rotating valve is with U-shaped valve pocket, and the cylindrical of rotating valve is with liquid-through hole, and the ceramic core body the other end is inserted with fule metering bar, and ceramic core body and fule metering bar are made by stupalith; The external circle of ceramic core is up and down respectively with water intake and water outlet, and the inner chamber of ceramic core body is with water chute, and water intake and water outlet communicate with the top and bottom of described water chute respectively, the uniform several groove of cylindrical of fule metering bar;
Further technological scheme is as follows:
Described liquid entering hole is all connected by nut with liquid inlet port and liquid outlet with liquid outlet;
Described cylinder body cylindrical is with a locating column, and locating column is in above liquid entering hole.
The invention has the advantages that: ceramic core body and fule metering bar are stupalith, have corrosion-resistant, high temperature resistant, the characteristic of long service life; With liquid-through hole on rotating valve, can control the flow of ceramicpump, and structure is simple, cost of production is low, stable performance.
Accompanying drawing explanation
Fig. 1 is explosive view of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes ceramic core body 1, one end interference fit cylinder body 2 of ceramic core body 1, cylinder body 2 cylindrical is with a locating column 21, and locating column 21 plays the fixing effect in location, cylinder body 2 circumference is with liquid entering hole 23 and liquid outlet 22, liquid entering hole 23 and liquid outlet 22 communicate with the inner chamber of ceramic core body 1 and symmetrical about cylinder body 2, liquid entering hole 23 with liquid inlet port 25 is installed respectively with liquid outlet 24 in liquid outlet 22 and is connected by nut 26, locating column 21 is positioned at above liquid entering hole 23, pottery core body 1 is inserted with rotating valve 4 with in the inner chamber of cylinder body 2 one end, the cylindrical of rotating valve 4 is with liquid-through hole 41, and the end of rotating valve 4, with U-shaped valve pocket 42, can make rotating valve 4 rotate by U-shaped valve pocket 42, the positive right or wrong of liquid-through hole 41 and liquid entering hole 23 is opened, the flow of control pump, the other end of pottery core body 1 is inserted with fule metering bar 3, and fule metering bar 3 can slide in the inner chamber of ceramic core body 1, measures the flow of pump and pressure etc., pottery core body 1 and fule metering bar 3 make by stupalith, make ceramicpump have corrosion-resistant, high temperature resistant, the life-span is long, the characteristic of stable performance, reduces cost of production, pottery core body 1 cylindrical is up and down respectively with water intake 32 and water outlet 31, the inner chamber of pottery core body 1 is with water chute, water intake 32 and water outlet 31 communicate with the top and bottom of described water chute respectively, fule metering bar 3 can slide in the inner chamber of Ceramic cylinder block 1, water from water intake 32 enter flow out from water outlet 31 time, the cylindrical of fule metering bar 3 is rinsed, prevent medicine or chemical liquid to fule metering bar 3 surface crystallization, affect the stability of ceramicpump, preferably, the uniform several groove 33 of cylindrical of fule metering bar 3, when fule metering bar 3 slides up and down along porcelain core body 1 inner chamber, especially when rotating fule metering bar 3, groove 33 and water chute can form larger free air space, advantageously in preventing fule metering bar 3 surface from producing crystallization.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
