Abstract
The utility model discloses a reversal valve. A cavity body, wherein, one end of which is provided with an inlet is arranged in a valve body of the utility model. A ball valve is abutted in the inlet. The other end of the ball valve is abutted on a spring, the other end of which is abutted on the top part of the cavity body, the lateral wall of which is provided with a water channel, the other port of which is through to the outer part of the valve body to form an outlet. The spring of the utility model and the inlet and the outlet of the valve body are not positioned on the same straight line, and therefore, when the utility model is used, the impact force received by the spring from concrete or water can be reduced, which leads the service life of the spring to be extended and leads the production efficiency to be improved.
Description
Technical field
The utility model relates to a kind of Reversal valve.
Background technique
The patent No. is 00243756.2, " a kind of forming concrete pile equipment that shakes " by name, a kind of forming concrete pile equipment that shakes is disclosed, this equipment such as Fig. 2, shown in Figure 3, be to be linked to be in-line by vibrating impacter 2 and vibrating impacter vibration damper 11, vibrating impacter guide rod 12, and connect whole external parallel at it and be provided with material guiding pipe 3, the top of material guiding pipe 3 has material feeding mouth 15, and the bottom has discharge port 9.When adopting this equipment to be carried out to pile driving construction, the material feeding mouth with material guiding pipe is connected with the concrete pump outlet of coagulation soil pressure filling device earlier, uses vibrating impacter pore-creating again, after the pore-creating, send the concrete pile with pump by material guiding pipe simultaneously at the lifting vibrating impacter.This model utility is to adopt vibrating impacter pore-creating, the soil body is had good compacted, the jolt ramming effect, and by the vibrating impacter vibrated concrete, can improve concrete degree of compaction, and the mandatory blending of slush and inter-pile soil, thereby native frictional force of stake week improved to pile body.In the above-mentioned forming concrete pile equipment that shakes, two critical components are arranged, one is Reversal valve, another is that unidirectional water is towards valve.Reversal valve and unidirectional water are the same towards the structure of valve, just are located at the position difference in the forming concrete pile equipment that shakes.Its structure all is to support card ball valve 24 in the inlet of valve body 21 as shown in Figure 3, and card spring 25 is supported on the top of ball valve 24, and the outlet port that is stuck in the valve body 21 is supported in the upper end of spring 25.As shown in Figure 3, unidirectional water is located in the water channel outlet of vibrating impacter 2 towards valve 18, and with vibrating impacter 2 pore-creating the time, the water of the water channel in the vibrating impacter 2 is washed unidirectional water open towards valve 18, one side pore-creating, one side water cooling.This moment, Reversal valve was closed.Shown in Figure 2, Reversal valve 10 is arranged in the discharge port of material guiding pipe 3, rises at vibrating impacter 2, and when using pump concrete, Reversal valve in the material guiding pipe 3 10 is washed open delivering concrete by concrete.Water channel in the vibrating impacter 2 stops to supply water at this moment, and unidirectional water is closed towards valve.Since Reversal valve or unidirectional water in the valve spring and the inlet/outlet of valve body become straight line, therefore, spring constantly is subjected to the impact of concrete or water in use, make that the working life of spring is very short, in the use, because spring is subjected to the infringement of concrete or water slug, and the normal operation of influence, be forced to stop work and production, change Reversal valve or unidirectional water, manufacturing efficiency is reduced towards valve.
Summary of the invention
The Reversal valve that the purpose of this utility model provides a kind of long service life, can enhance productivity.For achieving the above object, the utility model is taked following design proposal: a kind of Reversal valve, has the cavity that an end has import in its valve body, in this import, support the card ball valve, the other end of ball valve supports the card spring, and the other end of spring supports the top that is stuck in cavity, has water channel at the sidewall of cavity, the another port of water channel is led to outside the valve body, forms outlet.Because the spring in the Reversal valve and the inlet/outlet of valve body are not point-blank, therefore, the spring impact force that is subjected to concrete or water can reduce greatly in use, makes the growth in working life of spring.
In the utility model, described water channel is some.
In the utility model, be preferably: described water channel is two, and is symmetrical in the both sides of cavity.
The utility model has the advantages that: the spring in the Reversal valve of the present utility model and the inlet/outlet of valve body are not point-blank, therefore, the spring impact force that is subjected to concrete or water can reduce greatly in use, makes increase the working life of spring, has improved manufacturing efficiency.

Embodiment
As shown in Figure 1, structure of the present utility model is that the inlet in valve body 2 is provided with threaded collar 1, support card ball valve 3 by threaded collar 1, the other end of ball valve 3 supports card spring 5, and the other end of spring 25 supports the top that is stuck in cavity 6, has water channel 4 at the sidewall of cavity 6, the another port of water channel 4 is led to outside the valve body 2, form outlet, water channel 4 is two, and is symmetrical in the both sides of cavity 6.One end of cavity 6 is import, the other end sealing of cavity 6, after concrete or water back down ball valve 3 and enter cavity 6, directly flow away by the outlet of water channel 4 from water channel 4, reduced concrete or water impact force so widely to spring 5, make increase the working life of spring 5, thereby improved manufacturing efficiency.
As Fig. 2, shown in Figure 3, Reversal valve of the present utility model can be replaced the Reversal valve 10 in the former forming concrete pile equipment that shakes; Simultaneously, Reversal valve of the present utility model can be used as unidirectional water and uses towards valve, replaces in the former forming concrete pile equipment that shakes unidirectional water towards valve 18.Can improve the forming concrete pile efficiency of equipment of shaking widely like this.
Claims (3)
1, a kind of Reversal valve, it is characterized in that: have the cavity that an end has import in its valve body, in this import, support the card ball valve, the other end of ball valve supports the card spring, the other end of spring supports the top that is stuck in cavity, sidewall at cavity has water channel, and the another port of water channel is led to outside the valve body, forms outlet.
