Abstract
The utility model relates to a washing unit to the sealed chamber of double entry pump especially relates to a water seal pipe device for double entry pump. The utility model discloses a setting up the ball valve no. One between cross and tee bend, setting up the ball valve no. Two in the other one end of three -way, when the quality of water of double entry pump output changed, the switching between two ball valves can light simply be realized to this water seal pipe device to it is clean to guarantee to get into sealed intracavity flush fluid.
Description
Technical field
The utility model relates to a kind of Rinsing unit to double suction pump Seal cage, especially relates to a kind of water sealing (sealing water) pipe device for double suction pump.
Background technique
The modal sealing means of double suction pump has packing seal and mechanical seal.Packing seal operationally, because the filler in Seal cage and axle (axle sleeve) occur that friction generates heat, must be introduced sealing fluid and carry out rinsing to take away heat in Seal cage; Equally, mechanical seal operationally, because the heat rubbed and stirring produces can cause the damage of mechanical seal, also needs in Seal cage, introduce clean sealing fluid and rinses, in order to prevent the formation of impurity buildups, air bag, maintenance and improvement lubrication etc.Existing double suction pump water sealing (sealing water) pipe device has significant limitation, and when the medium character change of transport pump, the using effect of water sealing (sealing water) pipe device can decline, thus the sealing of pump may be caused to decline.
Model utility content
For overcoming the above problems, the utility model provides a kind of water sealing (sealing water) pipe device being applicable to double suction pump fed sheet of a media change of properties.
The technical solution adopted in the utility model is:
A kind of water sealing (sealing water) pipe device for double suction pump, comprise threeway, four-way, foreign side's pipe plug and water sealing (sealing water) pipe, it is characterized in that: the two ends, left and right of described four-way are all connected with threeway, one end, two ends up and down of four-way connects spigot, spigot is for connecting water-pumping chamber, and the other end foreign side's pipe plug is blocked; Describedly between four-way and threeway, be provided with a ball valve; The other two ends of described threeway connect water sealing (sealing water) pipe and No. two ball valves respectively, and the other end of No. two ball valves is blocked with foreign side's pipe plug, and the other end of water sealing (sealing water) pipe is connected with pump seal chamber by nut.
As preferably, described four-way is reducing cross.
As preferably, described threeway is equal tee.
The beneficial effect that the utility model obtains is: the utility model by arranging a ball valve between four-way and threeway, in other one end of threeway, No. two ball valves are set, when the change of water quality that double suction pump exports, the easily switching of simple realization between two ball valves of this water sealing (sealing water) pipe device energy, thus it is clean to ensure to enter washing solution in Seal cage.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 1, a kind of water sealing (sealing water) pipe device for double suction pump of the present utility model, comprise threeway 2, four-way 1, foreign side's pipe plug 5 and water sealing (sealing water) pipe 6, four-way 1 is reducing cross, be provided with four ports altogether, two, the left and right port of four-way 1 is all connected with a threeway 2, four-way 1 be equipped with a port up and down, wherein lower end mouth is connected with water-pumping chamber by spigot 7, and upper end-hole foreign side's pipe plug 5 is blocked; A ball valve 3 is provided with between the left and right port and the connecting port of threeway 2 of four-way 1; Threeway 2 is equal tee, threeway 2 is provided with three ports altogether, and a port is connected with four-way 1, and two-port is connected with No. two ball valves 4 with water sealing (sealing water) pipe 6 respectively in addition, the other end of No. two ball valves 4 is blocked with foreign side's pipe plug, and the other end of water sealing (sealing water) pipe 6 is connected with pump seal chamber by nut.
Principle of the present utility model is: during use, during when double suction pump conveying clear water or containing solid particle less medium, closes No. two ball valves 4, opens a ball valve 1, is introduced Seal cage to be sealed machine or filler rinses by water-pumping chamber's water outlet; When double suction pump conveying is containing the medium that solid particle is more, Seal cage is entered for avoiding impurity, the foreign side's pipe plug 5 on No. two ball valves 4 is taken off before start, then No. two ball valves 4 are connected sealing water pipe, the extraneous clean medium of supply in sealing water pipe, close a ball valve 3 again, open No. two ball valves 4, just can pass into clean medium from the external world and machine envelope or filler are rinsed.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from model utility spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
