Abstract
The utility model relates to a four-way valve for a sewage suction truck system, which includes a valve body, a valve core and a handle, wherein a valve cap is installed at the top of the valve body; the valve core is accommodated in the valve body; the handle is installed on the valve core through an inner hexagon screw, and can be used for pushing the valve core to rotate; O-shaped seal rings are arranged on the upper and the lower end surfaces of the valve core; and a sealing strip is arranged on the side surface of the valve core. Through arranging the O-shaped seal rings and the sealing strip in the four-way valve for the sewage suction truck system, the tightness inside the valve is guaranteed, and the suction performance of the system is improved; and the four-way valve has the advantages of flexibility, portability and convenience for operation, excellent sealing performance, high operating efficiency, solidness, durability and long service life.
Description
[technical field]
The utility model relates to the constituent elements of a kind of suction-type sewer scavenger system, is specifically related to a kind of four-way valve that is used for the suction-type sewer scavenger system.
[background technique]
The suction-type sewer scavenger system realizes the function of soil pick-up or pump drainage gas usually through vacuum pump.And air-breathing and conversion function exhaust are mainly accomplished through four-way valve in this system.
Yet the sealability of the four-way valve of existing technology is relatively poor, be easy to cause efficient air-breathing, exhaust lower, and working life is shorter.
Therefore, for solving the problems of the technologies described above, necessary a kind of structure improved four-way valve that is used for the suction-type sewer scavenger system that has is provided, to overcome said defective of the prior art.
[model utility content]
For addressing the above problem, the purpose of the utility model is to provide the four-way valve that is used for the suction-type sewer scavenger system of a kind of good airproof performance and long service life.
For realizing above-mentioned purpose, the technological scheme that the utility model is taked is: a kind of four-way valve that is used for the suction-type sewer scavenger system, and it comprises valve body, spool and handle; Wherein, in the top of said valve body one valve gap is installed; Said spool is contained in the valve body; Said handle is installed on the spool through a socket head screw, and it can promote valve core rotation; The upper and lower end face of said spool is provided with O-ring seals; The side of said spool is provided with Stamping Steel Ribbon.
The four-way valve that is used for the suction-type sewer scavenger system of the utility model further is set to: be provided with a pair of stop screw in said valve gap.
Compared with prior art, the utlity model has following beneficial effect: the four-way valve that is used for the suction-type sewer scavenger system of the utility model is through being provided with O-ring seals and Stamping Steel Ribbon, thereby guaranteed the tightness in the valve, improved the suction performance of system.This four-way valve has that flexible operation is light, the advantage of favorable sealing property, high working efficiency, sturdy and durable, long service life.

Fig. 2 is the plan view of the four-way valve that is used for the suction-type sewer scavenger system of the utility model.
Fig. 3 is the phase diagram of the four-way valve that is used for the suction-type sewer scavenger system when air-breathing of the utility model.
Fig. 4 is the phase diagram of the four-way valve that is used for the suction-type sewer scavenger system when exhaust of the utility model.
[embodiment]
See also shown in Figure of description 1 to the accompanying drawing 4, the utility model is a kind of four-way valve that is used for the suction-type sewer scavenger system, and it is made up of several parts such as valve body 1, spool 2 and handles 3.Wherein, said valve body 1 adopts the casting of high-quality grey cast iron with spool 2, thereby has strengthened wear-resisting property.Said handle 3 adopts Cast Steel, thereby has increased its resistance to flexure.
Wherein, the top of said valve body 1 is equipped with a valve gap 11, is provided with a pair of stop screw 12 in said valve gap 11.Further, be provided with 4 passages 13 in this valve body 1.
Said handle 3 is installed on the spool 2 through a socket head screw 4, and it can promote spool 2 and rotate, thereby air-breathing, the exhaust that realize this four-way valve are perhaps closed.
Said spool 2 is contained in the valve body 1, and it is communicated with 4 passages 13 in twos or this four-way valve is closed.The upper and lower end face of said spool 2 is provided with O-ring seals 21; The side of said spool 2 is provided with Stamping Steel Ribbon 22.Through said O-ring seals 21 and Stamping Steel Ribbon 22 are set, thereby guarantee the tightness in the valve, improved the suction performance of system.
The working principle of the four-way valve that is used for the suction-type sewer scavenger system of the utility model is following: during soil pick-up; With handle 3 to 45 ° of anticlockwises (through two stop screws 12; The angle of Joystick 3); At this moment vacuum pump produces negative pressure with the air sucking-off (see figure 3) in the filth storage can in jar, and the outer dirt of car passes through in another pipe inspiration jar of filth storage can.During blowdown, to 45 ° of right rotations, at this moment vacuum pump is thrown the air inspiration in the atmosphere in filth storage can (see figure 4) through this four-way valve with gas with handle 3, and the pressure in the filth storage can increases, and air pressure is discharged the dirt in the jar.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection domain of this creation.
Claims (2)
