Description
Technical field
The utility model relates to air valve, relates in particular to the adjustable manual air valve of dumping car industry and hydro-pneumatic field.
Background technique
At present, have similar manual air valve now owing to long-term pressurized causes the defective of the easy ageing failure of sealed member, thereby cause the airtight performance of air valve to reduce, if things go on like this directly influence the normal operation of the safety and the pneumatic system of gas transmission.The widely used manual air valve of domestic dumping car industry, it falls function slowly is improved on former control power take-off function, needs to operate respectively with two handles, inconvenient operation, and manually the handle of air valve adopts metallic material to make more, and is heavy, poor operability.
Summary of the invention
The utility model is at manually the air valve airtight performance is not good in the prior art, shortcomings such as complicated operation, provide a kind of and connected valve body and switch block by rotating shaft, and between valve body and switch block, be provided with sealing gasket, and the handle that adopts the high-density plastic to make, can effectively improve the seal of air valve and the adjustable manual air valve of operability.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The adjustable manual air valve, comprise valve body and handle, decline interface, gas source interface, lifting interface are set on the valve body, described valve body is provided with switch block, valve body is connected by rotating shaft with switch block, and rotating shaft is provided with the jackscrew nut, between jackscrew nut and the switch block flat gasket is set, handle comprises handle and is arranged on interior bar of handle and the button that is arranged on the handle rear end that bar is connected with switch block.
As preferably, be provided with plural straight pin between described valve body and the switch block, be provided with an elastic cylindrical pin between valve body and the handle.Fix by straight pin between valve body and the switch block,, very stable, firm when making pneumatic valve work between valve body and the handle by the elastic cylinder finger setting.
As preferably, be provided with sealing gasket between described valve body and the switch block.Sealing gasket is that rubber is made, owing to be provided with sealing gasket, has strengthened the airtight performance of air valve greatly, has prevented entering of profit in the operate outside environment, has protected manual air valve internal components, has prolonged the working life of manual air valve.
As preferably, described rotating shaft is provided with a fixing pin.Fix by straight pin between rotating shaft and the valve body.
As preferably, described handle is provided with the round platform table top.Handle is provided with the round platform table top that increases, and can strengthen feel, improves the operability of manual air valve greatly, and can with the button better fit, thereby the laying of more favourable and spring.
As preferably, be provided with spring between described handle and the button.
As preferably, described jackscrew nut is provided with perforate, and fastening screw trip bolt is installed in the perforate.On the jackscrew nut fastening screw trip bolt has been installed, has been made connection more stable.The plastics that handle adopts are high density polyethylene (HDPE) (code name HDPE), the advantage that the hardness with HDPE is big, fusing point is high, corrosion resistance is strong.The material of handle can also be aluminum or aluminum alloy, adopts aluminum or aluminum alloy to have stable performance, durable advantage.
The utility model is owing to adopted above technological scheme, have significant technique effect: the utility model connects valve body and switch block by rotating shaft, and between valve body and switch block, be provided with sealing gasket, and the handle that adopts the high-density plastic to make, can effectively improve the seal of air valve and the adjustable manual air valve of operability.
