Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment high-pressure cleaning machine gun valve;
Fig. 2 is the schematic side view of the utility model embodiment high-pressure cleaning machine gun valve;
Fig. 3 is the structural representation of high-pressure cleaning machine gun valve under the on state of the utility model embodiment water route.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public concrete enforcement.
As depicted in figs. 1 and 2, the rifle control valve unit of jetting machine comprises rifle valve pocket 10, comprising: rifle valve pocket 10, is provided with the passage of band water intake 1011 and water outlet 1031; Seal valve 20, is arranged in the described passage of described rifle valve pocket 10, for opening and closing the described passage in described rifle valve pocket 10; Spring 30, is located at the influent side of described seal valve 20, and one end of described spring 30 is butted on the inwall of described rifle valve pocket 10, and the other end of described spring 30 is butted on described seal valve 20; And plug 40, be arranged in described rifle valve pocket 10, inside is formed with a part for described passage, and has and coordinate with described seal valve 20 surface closing described passage.
Wherein, described seal valve 20 valve rod 202 that comprises flap 201 and be connected with described flap 201.In the present embodiment, flap 201 and valve rod 202 one-body molded.In other embodiments, flap and valve rod also can be connected by fixed block.
In one embodiment, between the matching surface of described flap and described plug, be provided with seal ring 50, thus improve sealing effect.In the present embodiment, as can be known from Fig. 1, under described spring action, described flap 201 closes described passage with the matching surface of described plug 40, and described valve rod 202 runs through plug 40, and is exposed to outside described rifle valve pocket 10.In order to increase sealing effect, between valve rod 202 and plug 40, be provided with seal ring.
In one embodiment, described plug end surface with between described flap for conical surface coordinates.And be located at the influent side of jetting machine hydraulic giant due to described spring, seal valve acts on while being subject to spring force and influent side water pressure, seal valve is contacted with plug, thus produce sealing, spring only provides initial pressure, thered is provided by water pressure afterwards, thus improve sealing effect, and sealing effect improves along with the increase of water pressure.
In one embodiment, as shown in Figure 3, rifle valve pocket 10 comprise there is water intake 1011 feed-water end 101, accommodate the middle part valve pocket 102 of seal valve 20 and plug 40 and there is the waterexit end 103 of water outlet 1031.Middle part valve pocket 102, seal valve 20 and plug 40 three are coaxial.
In order to reduce the axial length of rifle valve pocket 10, plug 40 adopts bottom end face axially locating.Plug 40 is that screw-thread fit plug 40 has screens groove 60 with the inner chamber of middle part valve pocket, during assembling, by this screens groove, tightens plug.
As shown in Figure 1, when water route is in off state, seal valve, under the acting in conjunction of spring force and influent side water pressure, makes seal valve be squeezed and disconnects water route.。
Move axially when producing under the effect of seal valve 20 in external force, as shown in Figure 3, spring 30 is squeezed shortening, and one end of seal valve 20 and plug 40 (i.e. both contact the conical surface) departs from, water route conducting.
The utility model additionally provides a kind of jetting machine, and described jetting machine comprises above-mentioned rifle control valve unit, and the interaction between the parts that described rifle control valve unit comprises and each parts, as above-mentioned, does not repeat them here.
The above-mentioned rifle control valve unit for jetting machine and jetting machine, by spring is located at influent side, pressure needed for sealing is provided by the pressure of spring and influent side water, improve sealing effect, not easily produce phenomenons such as leaking, and structure is simple, accuracy of manufacturing requires relatively low, effectively can also reduce the axial length of rifle valve pocket.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
