Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The simple overflow valve shown in fig. 1 comprises a valve body 1, a valve head 2 is arranged on one side of the valve body 1, a plugging component 3 is arranged on the other side of the valve body 1, and the simple overflow valve is characterized in that: in order to facilitate the subsequent overflow control, a plurality of overflow ports 4 are arranged on one side of the valve body 1, which is located on the valve head 2, and the overflow ports 4 can be configured with corresponding overflow pipelines during use. Meanwhile, in order to perform automatic overflow control according to the current flow pressure, a stopper 5 is provided inside the valve body 1. Specifically, the head end of the limiting plug 5 is connected with a limiting seat 6 through an elastic device, and an adjusting plug 7 is installed on the limiting seat 6. Therefore, in the default state, the adjusting plug 7 abuts against the valve head 2, and the side end of the adjusting plug 7 blocks the overflow opening 4. Therefore, the overflow valve can be kept in a closed state in a normal use state. When the pressure of the fluid flowing into the valve head 2 exceeds a preset value, the adjusting plug 7 overcomes the elastic force of the elastic device and starts to move inwards. The plug 7 is then adjusted away from the overflow 4 to allow fluid to drain from the overflow 4.

Combine the utility model discloses an embodiment of preferred sees, in order to possess the elastic support effect of preferred, and can effectively return back after the pressurized exceeds the limit value, resilient means is including the spring holder 8 who links to each other with stopper 5, and the cover is equipped with spring unit 9 on the spring holder 8. Meanwhile, the spacing seat 6 is inserted into the spring assembly 9. Therefore, the limiting seat 6 can be inserted to stably support the adjusting plug 7, unnecessary deflection of the adjusting plug 7 is avoided, and the overflow effect is improved.

Further see, the utility model discloses an adjust end cap 7 including the end cap body, the end cap body extends to the outside has the shutoff limit, is provided with the contact cock post on the end cap body, and when being in acquiescence state, the contact cock post supports valve head 2, and outer overflow mouth 4 is plugged up on the shutoff limit.

In connection with practical implementation, the valve head 2 is of flared configuration. Therefore, the fluid is convenient to introduce, and the connection with the reserved interface in the pipeline can be effectively realized. Meanwhile, the valve head 2 has a contact receiving wall extending inward. Therefore, the contact air tightness between the valve head 2 and the adjusting plug 7 can be better.

Still further, a sealing assembly 10 is arranged between the plugging assembly 3 and the valve body 1, and the sealing assembly 10 is an O-ring. Meanwhile, the plugging component 3 and the valve body 1 are combined stably and conveniently. And, valve body 1 periphery cover is equipped with supplementary constant head tank 11, and the valve body 1 of being convenient for links to each other with outside locating component, avoids valve body 1 to appear great swing because of fluid strikes during the use. Furthermore, a limit expansion ring 12 is arranged between the limit plug 5 and the valve body 1. Like this, can realize both stable interference fit, when preventing to suffer excessive impact, the shake appears in spacing stopper 5.
