Abstract
The utility model relates to an underwater electric shutoff valve comprising a valve body, a valve spool, a valve seat and a valve cover. An inwardly recessed step groove is arranged at the central portion of the valve body, and the bottom of the valve seat is in threaded connected with a first groove surface of the valve body and is sealed by a seal ring; an inwardly recessed circular groove is opened at the central portion of the valve seat, the circular groove is internally provided with the valve core, the outer wall surface of the valve core is in gap fit with the surface of the inwardly recessed circular groove opened in the valve seat, and the top portion of the valve core is provided with a return spring; electromagnetic coils are sleeved on the outer periphery of the valve seat and are fixed and locked tightly through a locking nut; and the valve cover is fastened on the valve body through screws and sealed by the seal ring. The underwater electric shutoff valve is simple in structure and reliable in sealing, can work normally underwater, can be widely applied to stop and conduct oil, gas and water media in systems of buoyancy adjusting systems, hydraulic pressure systems, etc., of underwater robots.
Description
Technical field
The utility model relates to valve, especially has sealability and is applicable to the Electric Actuated Stop Valves of underwater operation.
Background technique
Stop valve is as using a kind of widely General valve in all trades and professions, it mainly is used for making cut-out, distributes and change the flow direction of medium in pipeline.Electric Actuated Stop Valves commonly used at present is made up of electric actuator and stop valve two-part; Through the keying of the mobile realization pipeline of spool in valve body, because Electric Actuated Stop Valves need bear very big internal pressure in the course of the work and do not leak, still; The existing conventional Electric Actuated Stop Valves is because no pressure-resistant apparatus and sealability; All there is the phenomenon of leaking, the electric part of Electric Actuated Stop Valves proper functioning under water especially, need it is installed in the dry chamber or be soaked in the oil usually could proper functioning; Increased cost, troublesome poeration.
The model utility content
The applicant does not have sealing and withstand voltage shortcoming to stop valve in the above-mentioned existing technology; Provide a kind of rational in infrastructure, have the Electric Actuated Stop Valves under water of better sealability, thus can be to outside reliable sealing; Even under the situation of bearing very high internal pressure, also can move flexibly.
The technological scheme that the utility model adopted is following:
A kind of Electric Actuated Stop Valves under water comprises valve body, spool, valve seat and valve gap, and said valve body middle part is provided with the indent step trough, and said valve seat bottom is through being threadedly connected to the first groove surface place of valve body, and through the seal ring sealing; Said valve seat middle part has the indent circular groove, and spool is installed in the said circular groove, and said spool outer wall becomes Spielpassung with the indent circular groove face that valve seat is opened, and said spool top is provided with Returnning spring; Electromagnetic coil is set on the excircle of valve seat, and through the locking nut fixing and locking; Valve gap is anchored on the valve body through screw, and through the seal ring sealing.
Its further technological scheme is:
The even O RunddichtringO of said seal ring and seal ring.
The beneficial effect of the utility model is following:
Because valve seat and valve body be through being threaded, and seal through seal ring, thereby prevented the generation of stop valve internal leakage; Valve gap is anchored on the valve body through screw, and through the seal ring sealing, thereby make the stop valve integral sealing, prevented external leakage; Be that the utility model is functional,, can play sealing and withstand voltage effect, when in the deep-sea, using, resist the pressure of extraneous seawater and prevent that seawater from getting in the valve body because sealing is provided with valve gap on the valve body; The utility model is simple in structure, and sealing is reliable, can be directly proper functioning under water, can be widely used in the medium and the conducting of oil, gas, aqueous medium in the systems such as underwater robot buoyancy regulating system, hydraulic system.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model is described.
As shown in Figure 1; The described Electric Actuated Stop Valves under water of the utility model comprises valve body 9, spool 8, valve seat 3 and valve gap 1, and valve body 9 middle parts are provided with the indent step trough; Valve seat 3 bottoms are through being threadedly connected to the first groove surface place of valve body 9, and through 7 sealings of O RunddichtringO; Valve seat 3 middle parts have the indent circular groove, and spool 8 is installed in the circular groove, and spool 8 outer wall become Spielpassung with the indent circular groove face that valve seat 3 is opened, and spool 8 tops are provided with Returnning spring 5, and the bottom of spool 8 is structure coning; Electromagnetic coil 4 is set on the excircle of valve seat 3, and through locking nut 2 fixing and lockings; See Fig. 2, valve gap 1 is anchored on the valve body 9 through screw 10, and through 6 sealings of O RunddichtringO; Valve body 9 bottoms are provided with into the import P and outlet T of plumbness.
This practical working principle is following:
As shown in Figure 1, under the normality, because the effect of spool 8 top Returnning springs 5 makes spool 8 be in shown position, the conical structure and the valve body 9 of the bottom of spool 8 make contact to closed condition at this moment, i.e. not conducting between the import P of stop valve and the outlet T; When giving electromagnetic coil 4 energisings, its generation suction pulling spool 8 moves up, and makes spool 8 and valve body 9 break away from, and then valve port is opened, at this moment conducting between the import P of stop valve and the outlet T; After electromagnetic coil 4 power supplies were cancelled, its suction disappeared, and spool 8 resets under the effect of Returnning spring 5 thrusts, and the conical structure of spool 8 bottoms becomes closed condition again with valve port, ends again.Promptly through just realizing the conducting of valve port easily to the power supply of electromagnetic coil 4 and outage and closing.
Spool and valve body all adopt metallic material to process, thereby when spool is connected with valve body, produce sealing effect through metal and Metal Contact, reach the form of metal hard-sealing; So the good sealing effect of the utility model can be suitable for by water, gas, the various media of wet goods, and because the existence of seal ring 1 and seal ring 6, make electromagnetic coil 4 and extraneous effective isolation, so the utility model can directly be worked under water.
More than describing is the explanation to the utility model, is not the qualification to model utility, and the utility model institute restricted portion within the protection domain of the utility model, can be done any type of modification referring to claim.
