Abstract
A valve mounting for securing a valve body between two spaced apart mounting members having hydraulic studs which are elongated by pressure for release of the clamping engagement of the valve body for its quick and easy installation and removal. A preferred form of the present invention includes the application of a plurality of valve modules connected to the exterior of an elongate block manifold body through the use of hydraulic studs to control the flow into one of the longitudinal passages extending through the manifold body.
Claims6
A valve and valve mounting comprising
- a first mounting member,
- a second mounting member spaced from said first mounting member,
- a valve having a body, a valve member and a valve actuator,
- a plurality of hydraulic tensioning members secured by securing means to each of said mounting members, said hydraulic tensioning members having a connection for the supply of hydraulic fluid under pressure whereby said tensioning members are elongated by such pressure,
- said mounting members being spaced sufficiently apart to allow said valve body to pass therethrough when said tensioning members are elongated by hydralic pressure,
- the body of said valve having a width slightly smaller than the distance between said first and second mounting members when said tensioning members are elongated by hydraulic pressure, and
- means on said tensioning members for tightening the securing means to one of said mounting flanges while said tensioning members are elongated under pressure whereby with said valve body positioned between said flanges release of the hydraulic pressure on said tensioning members moves said flanges into tight engagement with said valve body.

A block manifold comprising
- an elongate body having a first longitudinal passage extending therethrough,
- means at one end of said elongate body for connecting to said first passage,
- a first transverse passage through said body communicating with said first longitudinal passage,
- a valve having a body, a passageway therethrough, a valve member and an actuator,
- said valve positioned against said body with its passage in alignment with said first transverse passage,
- a flow line having an end flange spaced from the side of said manifold body by a distance slight more than the width of said valve body,
- a plurality of hydraulic stud tensioners extending through said flange, past said valve body in spaced relation thereto and threadedly engage within said manifold body around the opening of said transverse passage, and
- a nut on each of said hydraulic stud tensioners engaging the side of said flange facing away from said manifold body,
- hydraulic pressure being supplied to said tensioners to cause them to elongate during the installation and removal of said valve body from engagement with said manifold body and venting of hydraulic pressure from said tensioners clamping said valve body tightly between said flange and said manifold body.
