Abstract
The utility model discloses a unidirectional throttle valve which comprises the following components: a valve body, a pressure gauge, and a valve core which controls unidirectional conduction of the valve body. The valve core is provided with an elastic component which keeps a unidirectional closing trend of the valve body. As an improvement of the unidirectional throttle valve, the unidirectional throttle valve furthermore comprises a fine adjusting device which is matched with the valve core for adjusting opening degree of the valve core. According to the unidirectional throttle valve, through equipping the fine adjusting device on the valve body, a minimum flow and a minimum pressure of the unidirectional throttle valve can be adjusted accurately, thereby preventing incapability of opening the valve body because of insufficient pressure of the inlet liquid. The unidirectional throttle valve compensates the insufficiencies of the prior-art unidirectional throttle valve, complements and enriches the functions of the valve body.
Description
Technical field
The utility model relates to a kind of one-way throttle valve, the especially a kind of one-way throttle valve that can finely tune flow.
Background technique
One-way throttle valve is through changing the restriction area of passage, and then can regulate enters into the flow of hydraulic pressure or pressure system, when importing and exporting transposing; Rely on liquid or gas pressure; Open throttle valve, throttle valve is opened and must be satisfied liquid or gas pressure greater than spring force and frictional force sum, otherwise can not open; As a rule, this individual event throttle valve is difficult to satisfy the needs of producing regulation and control.
Summary of the invention
The utility model is for solving existing technology in use, and the defective of existence provides a kind of not enough one-way throttle valve of existing valve body that remedies.
The technological scheme that the utility model solves existing issue is: a kind of one-way throttle valve; Comprise valve body, pressure gauge, the spool of the unidirectional conducting of control valve body; Described spool is provided with the elastic member that keeps the unidirectional closed trend of valve body; Improve as the utility model, comprise that also one cooperates the vernier device of regulating spool unlatching with spool.
As the further improvement of the utility model, described vernier device is arranged on the valve body, and vernier device comprises the catch bar of valve body displacement relatively, and catch bar matches with spool.
As the further improvement of the utility model, described vernier device is provided with the block of location catch bar, and described block is bolted on the valve body.
As the further improvement of the utility model, described catch bar is provided with the screw thread that cooperates with block or valve body.
As the further improvement of the utility model, described elastic member is the spring that is arranged in the valve body and acts on spool.
As the further improvement of the utility model, described vernier device is provided with the swing handle that is connected on the catch bar.
As the further improvement of the utility model, described one-way throttle valve is provided with the pressure gauge that can read pressure.
The utility model compared with prior art, its beneficial effect is through vernier device being set on valve body, can accurately regulating the minimum discharge and the pressure of one-way throttle valve, being unlikely to can't open valve body because of the underpressure of import liquid.The utility model has remedied the deficiency of one-way throttle valve, replenishes and has enriched the valve body function.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, this case study on implementation comprises: valve body 1, pressure gauge, the spool 2 of control valve body 1 unidirectional conducting, spool 2 are provided with the elastic member 3 that keeps valve body 1 unidirectional closed trend, cooperate the vernier device that regulating spool 2 is opened with spool 2.For easy to use, elastic member 3 is the spring that is arranged in the valve body 1 and acts on spool 2.
Be specially in this case study on implementation, vernier device is arranged on the valve body 1, and vernier device comprises the catch bar 41 of valve body 1 displacement relatively, and catch bar 41 matches with spool 1.Vernier device is provided with the block 42 of location catch bar 41, and block 42 is bolted on the valve body 1, and catch bar 41 is provided with the screw thread that cooperates with block 42 or valve body 1.
For the ease of using, vernier device is provided with the swing handle 43 that is connected on the catch bar 41, twisting swing handle 43; Driving catch bar 41 rotates; Catch bar 41 moves under the effect of valve body 1 or the screw thread location on 42 of blocking a shot, and reaches fine setting and promotes spool 2; Change the trend of spool 2 closures, thus accurate control valve body flow.
