Abstract

The utility model discloses a water conservation leak protection valve, including one -level case and second grade case, the one -level case includes one -level valve cap and one -level valve rod, the water service pipe has transversely been placed to the lower part of one -level valve rod, and the terminal vertical inner chamber middle part of locating the water service pipe of inserting in the bottom of one -level valve rod, the terminal surface in bottom of one -level valve rod has still been seted up and has been run through the through -hole, the inside of one -level valve rod is the vertical inner chamber of having seted up still, threaded structure is seted up to the internal surface of inner chamber, the lower part of second grade valve rod connects to insert through the helicitic texture soon locates interior intracavity, the movable joint is all installed at the both ends of water service pipe. This water conservation leak protection valve adds the mesh of establishing that the through -hole has reached current -limiting and water conservation that runs through in the bottom of one -level case for fluidic speed is even, uses through the combination of one -level case and second grade case to make the throttle effect show more, and it is controllable also to make fluidic speed reach.

Description

A kind of water saving, leak-proof valve

Technical field

This utility model relates to manually-operated gate technical field, is specially a kind of water saving, leak-proof valve.

Background technology

Valve is the control parts in fluid delivery system, has cut-off, regulation, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of fluid control systems, various valves used from simplest stop valve to extremely complex robot control system(RCS), its kind and specification are the most various.Manually-operated gate is extremely difficult to the purpose of current limliting in actual applications, and general valve is all single spool structure, it is not easy to reach the purpose of current limliting and water saving, and the speed of fluid is not easy to control.

Utility model content

The purpose of this utility model is to provide a kind of water saving, leak-proof valve, with the problem solving to propose in above-mentioned background technology.

nullFor achieving the above object，This utility model following technical scheme of offer: a kind of water saving, leak-proof valve，Including one-level spool and secondary valve core，Described one-level spool includes one-level bonnet and one-level valve rod，The top of described one-level valve rod is fixing with in the middle part of the lower surface of one-level bonnet to be connected，The lower, transverse of described one-level valve rod is placed with water service pipe，And the bottom end of one-level valve rod is vertically inserted in the middle part of the inner chamber of water service pipe，The bottom end outer surface of described one-level valve rod is further opened with running through through hole，The inside of described one-level valve rod the most vertically offers inner chamber，The inner surface of described inner chamber offers helicitic texture，Described secondary valve core includes secondary valve bar and secondary valve cap，The top of described secondary valve bar is fixing with in the middle part of the lower surface of secondary valve cap to be connected，The bottom of described secondary valve bar is spun by helicitic texture and is inserted in interior intracavity，The two ends of described water service pipe are mounted on movable joint.

Preferably, the outer wrap of described secondary valve core has elastomeric material.

Preferably, the external device (ED) of described water service pipe has frost retarding layer.

Preferably, it is mounted on filter screen at described movable joint

Preferably, the outer surface of described secondary valve bar also offers helicitic texture, and adaptive with the helicitic texture of the inner surface of inner chamber

Compared with prior art, the beneficial effects of the utility model are: what this water saving, leak-proof valve added in the bottom of one-level spool run through through hole has reached the purpose of current limliting and water saving, the speed making fluid is uniform, it is applied in combination so that restriction effect is more significantly by one-level spool and secondary valve core, also makes the speed of fluid reach controlled.

Accompanying drawing explanation

Fig. 1 is this utility model schematic diagram；

Fig. 2 is this utility model movable joint cross-sectional view.

In figure: 1 one-level spool, 11 one-level bonnets, 12 one-level valve rods, 2 water service pipes, 3 run through through hole, 4 inner chambers, 5 secondary valve cores, 51 secondary valve bars, 52 secondary valve caps, 6 movable joints, 7 frost retarding layers, 8 filter screens.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.

nullRefer to Fig. 1-2，A kind of technical scheme of this utility model offer: a kind of water saving, leak-proof valve，Including one-level spool 1、One-level bonnet 11、One-level valve rod 12、Water service pipe 2、Run through through hole 3、Inner chamber 4、Secondary valve core 5、Secondary valve bar 51、Secondary valve cap 52、Movable joint 6、Frost retarding layer 7 and filter screen 8，One-level spool 1 includes one-level bonnet 11 and one-level valve rod 12，The top of one-level valve rod 12 is fixing with in the middle part of the lower surface of one-level bonnet 11 to be connected，The lower, transverse of one-level valve rod 12 is placed with water service pipe 2，The outside of water service pipe 2 is lined with frost retarding layer 7，Fluid in the case of low temperature is made to be not susceptible to icing phenomenon by adding frost retarding layer 7，And the bottom end of one-level valve rod 12 is vertically inserted in the middle part of the inner chamber of water service pipe 2，The bottom end outer surface of one-level valve rod 12 is further opened with running through through hole 3，Run through through hole 3 is equipped with passing through of beneficially fluid，The inside of one-level valve rod 12 the most vertically offers inner chamber 4，The inner surface of inner chamber 4 offers helicitic texture，The stability making valve body by adding helicitic texture effectively improves，Avoid valve rod to slip to cause the accident，Secondary valve core 5 includes secondary valve bar 51 and secondary valve cap 52，The outer wrap of secondary valve core 5 has elastomeric material，The throttling leakage prevention making valve body by adding elastomeric material is strengthened，The top of secondary valve bar 51 is fixing with in the middle part of the lower surface of secondary valve cap 52 to be connected，The outer surface of secondary valve bar 51 also offers helicitic texture，And it is adaptive with the helicitic texture of the inner surface of inner chamber 4，The bottom of secondary valve bar 51 is spun by helicitic texture and is inserted in inner chamber 4，The two ends of water service pipe 2 are mounted on movable joint 6，Facilitate the installation and removal of water pipe，The opening inner side of movable joint 6 is mounted on filter screen 8，By add filter screen 8 avoid impurity enter water service pipe 2 result in blockage.
