The technical solution of the utility model is achieved in that a kind of ball valve with spring energy storage sealing configuration, it comprises valve body, valve gap, end cap, valve rod, back shaft, spheroid, valve seat, offer passage in the described end cap, described valve seat is arranged on the inwall of end cap, described spheroid is arranged on the valve body lumen, the left and right sides of described spheroid contacts with valve seat respectively, the upper end of described spheroid is connected with valve rod, the lower end of described spheroid is connected with back shaft, the left and right sides of described valve body is connected with end cap respectively, the upper end of described valve body is connected with valve gap, the lower end of described valve body is connected with back shaft, described valve rod passes top and the valve gap of described valve body, the bottom of described valve rod links to each other with spheroid, described back shaft passes the bottom of described valve body, and the top of described back shaft links to each other with spheroid, between the top and valve gap of described valve body, between valve body and the end cap, between described valve seat and the end cap, be respectively arranged with one group of spring energy storage seal ring between the bottom of described valve body and the back shaft.
Preferably, between the top and valve gap of described valve body, between valve body and the end cap, between described valve seat and the end cap, be respectively arranged with a circle seal groove between the bottom of described valve body and the back shaft, described spring energy storage seal ring is located in the described seal groove.
Preferably, described spring energy storage seal ring comprises elastic skeleton, energy-storaging spring, is provided with circle " U " type groove on the described elastic skeleton, and described energy-storaging spring is arranged in described " U " type groove.
The utility model has the advantages that: simple in structure, after the spring energy storage seal ring is installed in the seal groove, the energy-storaging spring pressurized, make elastic skeleton and seal groove surface close contact, form thus sealing, energy-storaging spring provides permanent elastic force to elastic skeleton, and can remedy skew or off-centre that sealing material weares and teares and is mated part, and sealability is effective.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Fig. 1 is the structural representation of the present embodiment;
Fig. 2 is the partial enlarged drawing at A place among Fig. 1;
Fig. 3 is the partial enlarged drawing at B place among Fig. 1;
Fig. 4 is the partial enlarged drawing at C place among Fig. 1;

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
Consult Fig. 1 to shown in Figure 5, a kind of ball valve with spring energy storage sealing configuration of the present embodiment, it comprises valve body 1, valve gap 2, end cap 3, valve rod 4, back shaft 5, spheroid 6, valve seat 7, offer passage 9 in the end cap 3, valve seat 7 is arranged on the inwall of end cap 3, spheroid 6 is arranged on valve body 1 lumen, the left and right sides of spheroid 6 contacts with valve seat 7 respectively, the upper end of spheroid 6 is connected with valve rod 4, the lower end of spheroid 6 is connected with back shaft 5, the left and right sides of valve body 1 is connected with end cap 3 respectively, the upper end of valve body 1 is connected with valve gap 2, the lower end of valve body 1 is connected with back shaft 5, valve rod 4 passes top and the valve gap 2 of valve body 1, and the bottom of valve rod 4 links to each other with spheroid 6, and back shaft 5 passes the bottom of valve body 1, the top of back shaft 5 links to each other with spheroid 6, between the top of valve body 1 and the valve gap 2, between valve body 1 and the end cap 3, between valve seat 7 and the end cap 3, be respectively arranged with one group of spring energy storage seal ring 11 between the bottom of valve body 1 and the back shaft 5.
Wherein, between the top of valve body 1 and the valve gap 2, between valve body 1 and the end cap 3, between valve seat 7 and the end cap 3, be respectively arranged with a circle seal groove 10 between the bottom of valve body 1 and the back shaft 5, spring energy storage seal ring 11 is located in the seal groove 10.
Extremely shown in Figure 5 such as Fig. 2, the structure of the spring energy storage seal ring 11 in the present embodiment is: spring energy storage seal ring 11 comprises elastic skeleton 12, energy-storaging spring 13, be provided with a circle on the elastic skeleton 12 " U " type groove 8, energy-storaging spring 13 is arranged on " U " in the type groove 8.
When spring energy storage seal ring 11 be installed to seal groove 10 interior after, energy-storaging spring 13 pressurizeds, energy-storaging spring 13 behind the pressurized gives the power of 12 1 bounce-backs of elastic skeleton, force the surperficial close contact of elastic skeleton 12 and seal groove 10, form thus sealing, energy-storaging spring 13 provides permanent elastic force for elastic skeleton 12, and can remedy skew or the off-centre of sealing material wearing and tearing and mating parts, when the pressure medium that is subject to ball valve inside is done the time spent, can convert pressure medium to sealing force, pressure medium is larger, sealing force is just larger, and sealing is just more reliable, so no matter to be in the situation that low pressure or high pressure, the spring energy-storage seal ring will under spring force and pressure medium effect, can both be realized reliable sealing.
