Abstract
The utility model relates to a discharging valve, particularly to a straight-tube type unidirectional discharging valve, which comprises a discharging valve seat, a discharging spring, a spring ejector rod, a steel ball, an opening and closing valve seat, and a discharging gasket group. A discharging gasket is arranged at one end of the discharging valve seat; in the discharging valve seat, the steel ball, the spring ejector rod and the discharging spring are sequentially arranged along the inner side of the discharging gasket; and a sealing ring is arranged outside the discharging valve seat. The discharging valve is characterized in that a straight tube-shaped space is formed inside the discharging valve seat, and the spring ejector rod and the discharging spring are arranged inside the straight tube-shaped space, The tube space inside the discharging valve seat, which is used for arranging the spring ejector rod and the discharging spring, adopts a straight structure, that is, no steps are formed on the inner wall of the discharging valve seat, so that the discharging spring can not lose function after being impacted by the return high pressure of the discharging spring.
Description
Technical field
The utility model is a kind of unidirectional discharge valve, particularly a kind of unidirectional discharge valve of straight-tube that is used for spray coating mechanical or spray gun.
Background technique
Existing discharge valve, its structure as shown in Figure 1, it is made up of discharging valve seat 1, discharging spring 2, spring spindle 3, steel ball 4, switching valve seat 5, discharging pad 6, discharging spring 2 and spring spindle 3 are located in the tubular space of discharging valve seat 1, there is a step 7 in the central authorities of tubular space, one side that tubular space is thinner is provided with discharging spring 2, one side the thicker spring spindle 3 that is provided with.The shortcoming of this kind structure is when beating high pressure, and discharging spring 2 is subject to that high pressure backwashes and on the stuck step 7 in the discharging valve seat, causes herein one-way valve to lose efficacy and effectively suction and discharge.
Summary of the invention
The purpose of this utility model is in order to overcome the effectively defective of suction and discharge of existing discharge valve, to invent the unidirectional discharge valve of straight-tube that the interior tubular space of a kind of discharging valve seat is straight-tube shape.
The purpose of this utility model realizes as follows: the unidirectional discharge valve of described straight-tube, form by discharging valve seat, discharging spring, spring spindle, steel ball, switching valve seat, discharging pad, the discharging pad is located at an end of discharging valve seat, in the discharging valve seat, inboard along the discharging pad is provided with steel ball, spring spindle and discharging spring successively, the outside of discharging valve seat is provided with seal ring, it is characterized in that: be provided with tubular space always in the discharging valve seat, spring spindle and discharging spring are arranged in this straight tube-like space.
Good effect of the present utility model is as follows: owing to be used to be provided with the tubular space of spring spindle and discharging spring in the discharging valve seat is the straight tube-like structure, and just the inwall of discharging valve seat does not have step, so avoided the discharging spring to lose efficacy because of high pressure backwashes.
Description of drawings
Fig. 1 is existing discharge valve structural drawing
Fig. 2 is the utility model structural drawing
Among the figure: 1 discharging valve seat, 2 discharging springs, 3 spring spindles
4 steel balls 5 open and close valve seat 6 discharging pads
7 steps, 8 seal rings, 9 straight tube-like spaces
Embodiment
As shown in Figure 2, the unidirectional discharge valve of described straight-tube, form by discharging valve seat 1, discharging spring 2, spring spindle 3, steel ball 4, switching valve seat 5, discharging pad 6, discharging pad 6 is located at an end of discharging valve seat 1, in the discharging valve seat 1, inboard along discharging pad 6 is provided with steel ball 4, spring spindle 3 and discharging spring 2 successively, the outside of discharging valve seat 1 is provided with seal ring 8, it is characterized in that: be provided with tubular space 9 always in the discharging valve seat 1, spring spindle 3 and discharging spring 2 are arranged in this straight tube-like space 9.
During use, water is entered by discharging pad 6 places, and steel ball is backed down by water, makes spring spindle push down the discharging spring inwards; When not intaking, the pressure of discharging spring makes steel ball push down the switching valve seat.
