The check valve in the prior art includes a valve body, a piston and a pressure cap, the piston is arranged in the inner cavity of the valve body, the pressure cap is screwed tightly with the valve body, and one end of the valve body is provided with an air inlet, so One end of the pressure cap is provided with an air outlet. The one-way valve with the above structure has the following disadvantages: since both ends of the one-way valve are connected to the pipeline, in some occasions where the length of the pipeline has been determined, and the height of the one-way valve has been determined, it cannot be installed. If the pipeline is replaced again, the material cost and installation cost will be increased; if another one-way valve is replaced, it cannot be guaranteed to obtain a one-way valve that is just at the same height as the distance between the two pipelines, resulting in failure to install normally .
发明内容Contents of the invention
本发明要解决的技术问题是，提供一种在一定长度范围内能保证正常安装在两根管路之间、且能降低材料成本和安装成本的单向阀。The technical problem to be solved by the present invention is to provide a one-way valve which can ensure normal installation between two pipelines within a certain length range and can reduce material cost and installation cost.
本发明的技术方案是，提供一种具有以下结构的单向阀，包括阀体、活塞和压帽，所述活塞设在阀体的内腔，所述阀体的一端设有进气口，所述压帽的一端设有出气口，所述阀体与压帽之间还设有能调整单向阀高度的调整结构。The technical solution of the present invention is to provide a check valve with the following structure, including a valve body, a piston and a pressure cap, the piston is arranged in the inner cavity of the valve body, and an air inlet is provided at one end of the valve body, One end of the pressure cap is provided with an air outlet, and an adjustment structure capable of adjusting the height of the one-way valve is also provided between the valve body and the pressure cap.
所述调整结构是指，所述压帽套接在阀体上，所述阀体的外螺纹上旋合有锁紧螺母，所述锁紧螺母与压帽的端面相抵，并用多枚螺栓周向固定，所述阀体的内螺纹孔旋紧有螺帽，所述螺帽与阀体密封，所述螺帽与压帽密封。The adjustment structure refers to that the pressure cap is sleeved on the valve body, and a lock nut is screwed on the external thread of the valve body. fixed in the direction, the inner threaded hole of the valve body is screwed with a nut, the nut is sealed with the valve body, and the nut is sealed with the pressure cap.
所述螺帽与阀体密封是指，所述螺帽与阀体之间设有密封圈。The sealing between the nut and the valve body means that a sealing ring is provided between the nut and the valve body.
所述螺帽与压帽密封是指，所述螺帽与压帽之间设有密封圈。The sealing between the nut and the pressure cap means that a sealing ring is provided between the nut and the pressure cap.
采用上述结构后，本发明单向阀与现有技术相比，具有以下优点：由于所述阀体与压帽之间还设有能调整单向阀高度的调整结构，在一定范围内，通过旋转压帽就可以改变单向阀的高度，而压帽的上下伸缩，通过螺帽上的密封件的作用，均能保证单向阀的内通道的密封，这样在一定长度范围内，能保证正常安装在两根管路之间，避免重新更换管路或者单向阀，能降低材料成本和安装成本。After adopting the above structure, compared with the prior art, the check valve of the present invention has the following advantages: since there is an adjustment structure capable of adjusting the height of the check valve between the valve body and the pressure cap, within a certain range, through The height of the one-way valve can be changed by rotating the pressure cap, and the up and down expansion and contraction of the pressure cap can ensure the sealing of the inner channel of the one-way valve through the function of the seal on the nut, so that within a certain length range, it can ensure It is normally installed between two pipelines, avoiding replacement of pipelines or check valves, which can reduce material costs and installation costs.
