笼式单座调节阀
本技术属于管道阀门领域，特别涉及一种无内漏、使用效果好的笼式单座调节阀。
技术介绍
调节阀在管道里是非常常见的，调节阀中密封性是一个非常重要的，密封性能对调节阀的使用有重大的影响，我司在2011年公开申请了一种笼式单座调节阀，通过增设缠绕垫来大大提高密封性能，这样改变虽然增强了密封性能，但在实际使用中还是发现了某些不足，不同厂家或不同材质的缠绕垫，其压缩量不能很好的控制，而密封性能对压缩量要求是非常精确的，所以密封性能还是不稳定，没办法精准控制，同时还有可能发生内漏，对调节阀正常使用带来影响，使用非常不便。本技术要解决的技术问题是提供一种密封性能好、压缩量控制精准、不易发生内漏的新型笼式单座调节阀。
技术实现思路
为解决上述现有技术密封性能不好、压缩量控制不精准、易发生内漏、使用不方便等问题，本技术采用如下技术方案：本技术提供一种笼式单座调节阀，包括阀体、阀盖、笼状套筒、阀杆和阀塞，所述阀盖固定连接设置在阀体顶部轴心处，所述阀盖内设有填料弹簧，所述阀体内设有第一腔室和第二腔室，所述笼状套筒设于阀体内且位于第一腔室与第二腔室之间，所述笼状套筒上设有连接第一腔...
