Abstract
A water feed non-return valve comprises an upper valve body and a lower valve body. A water inlet is arranged in the upper valve body, and a water outlet is arranged in the lower valve body. The water feed non-return valve is characterized in that a valve spool rack is arranged on the inner walls of the upper valve body and the lower valve body, a location hole is arranged in the valve spool rack, a valve spool is arranged in the location hole, a valve cap is arranged at the upper end of the valve spool, a compression spring is arranged between the valve cap and the valve spool rack, and a valve plate is arranged at the lower end of the valve spool and hermetically contacts with the valve spool rack. During operation, water enters the valve body from the water inlet of the upper valve body to impact on the valve plate, and overcomes the elastic force of the compression spring arranged between the valve cap and the valve spool rack to enable the valve plate to detach from the valve spool rack, so as to connect the water inlet and the water outlet of the non-return valve. When water stops entering the valve body, the valve plate automatically returns to the original position under the action of the elastic force of the compression spring to close the non-return valve, so as to prevent water from backwardly flowing.
Description
Technical field
The utility model relates to a kind of Water Check Valve of going up, and belongs to valve field, is mainly used in the vertical watering pipeline.
Background technique
Safety check claims reflux valve, back pressure valve, one-way valve etc. again, this class valve is that tube road medium itself flows the power produced and opens automatically, belong to a kind of automatic valve, has strict directivity, safety check is used for pipe-line system, it mainly acts on is to prevent that the medium in the pipeline from flowing backwards, and therefore can be widely used in oil, chemical industry, mineral products, plumbing and every profession and trades such as food, pharmacy, and in people's daily life.Along with the development of society, little high level, tall building get more and more, because the building storey height, as direct water from the pipeline of ground, can run into because of pressure of supply water is not enough and cause current little, perhaps cause shortcomings such as water inconvenience, more so the roof of tall building is equipped with wet pit because of cutting off the water.In giving the wet pit water storage process of eminence,, need in pipeline straight up, safety check be installed for preventing to stop suddenly or pipeline blockage down flows backwards water because of supplying water.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of and be applied in the vertical watering pipeline, is the last Water Check Valve that prevents to stop suddenly because of supplying water or pipeline blockage down flows backwards water.
The technological scheme of Water Check Valve is on the utility model: comprise upper valve body and following valve body, be shaped on water intake in the upper valve body, be shaped on water outlet in the following valve body, it is characterized in that on described upper valve body and the following valve interior wall valve core frame being installed, be shaped on positioning hole in the valve core frame, spool is installed in the hole in the position, top, bonnet is installed in the upper end of spool, between bonnet and the valve core frame pressure spring is installed, is shaped on valve block in the lower end of spool, valve block contacts with the valve core frame sealing.
The Water Check Valve of going up of the present utility model, on described upper valve body and following valve interior wall, valve core frame is installed, be shaped on positioning hole in the valve core frame, spool is installed in the hole in the position, top, bonnet is installed in the upper end of spool, between bonnet and the valve core frame pressure spring is installed, is shaped on valve block in the lower end of spool, valve block contacts with the valve core frame sealing.During work, current enter valve body impact valve block from the water intake of upper valve body, and overcome the elastic force of the pressure spring of installing between bonnet and the valve core frame, and valve block and valve core frame are disengaged, thus the entery and delivery port of conducting safety check; After current stop to enter valve body, automatically reset at the elastic force effect lower valve of pressure spring, close safety check, current can not flow backwards.
The Water Check Valve of going up of the present utility model is shaped on sealing surface on the described valve core frame, and seal ring is installed on the valve block, and seal ring contacts with sealing surface, has had seal ring to contact with the sealing surface of valve core frame, and sealing effect is better.Described upper valve body and following valve body are that pvc material is made, and pvc material intensity is good, and is anti-aging, corrosion-resistant, long service life.
Description of drawings
Fig. 1 is the structural representation of Water Check Valve on the utility model.
Embodiment
The utility model relates to a kind of Water Check Valve of going up, be mainly used in the vertical watering pipeline, as shown in Figure 1, comprise upper valve body 1 and following valve body 2, be shaped on water intake 3 in the upper valve body, be shaped on water outlet 4 in the following valve body, it is characterized in that installing on described upper valve body 1 and following valve body 2 inwalls valve core frame 5, be shaped on positioning hole 6 in the valve core frame, spool 7 is installed in the hole in the position, top, and bonnet 8 is installed in the upper end of spool, and pressure spring 9 is installed between bonnet 8 and the valve core frame 5, be shaped on valve block 10 in the lower end of spool 7, valve block 10 contacts with valve core frame 5 sealings.During work, current enter valve body impact valve block 10 from the water intake 3 of upper valve body 1, and overcome the elastic force of the pressure spring of installing between bonnet 8 and the valve core frame 59, and valve block 10 and valve core frame 5 are disengaged, thus the entery and delivery port of conducting safety check; After current stop to enter valve body, automatically reset at the elastic force effect lower valve 10 of pressure spring 9, close safety check, current can not flow backwards.Be shaped on sealing surface 11 on the described valve core frame, seal ring 12 is installed on the valve block 10, seal ring 12 contacts with sealing surface 11, has had seal ring to contact with the sealing surface of valve core frame, and sealing effect is better.Described upper valve body 1 and following valve body 2 are that pvc material is made, and pvc material intensity is good, and is anti-aging, corrosion-resistant, long service life.
